Description

 The invention relates to refrigeration and may find application in domestic refrigerators.

A known method of controlling a thermoelectric refrigerator, in which the temperature inside the refrigerator is set, the current value of the same temperature is measured, their difference is determined according to which the control signal of the thermoelectric battery is generated, heat is removed from the refrigerator through the external radiator of the thermoelectric battery [1]
Also known is a control system for its implementation, comprising a temperature setter inside the refrigerator, a sensor of the same temperature, a subtracting element, a control device and a thermoelectric battery with an external radiator [1]
This method and control system, based on the Peltier effect using a thermoelectric battery, have several advantages compared to compression refrigerators, namely, they are environmentally friendly, noiseless, more reliable. However, due to the low efficiency with a significant temperature difference in the heated room where the refrigerator is installed and inside the refrigerator (usually not lower than 15 ^o C), this method and the control system that implements it consumes significantly more electricity compared to refrigerators compression and even adsorption type.

 The formation of the control signal according to the relay principle, which is used in the aforementioned method and system, further aggravates this drawback.

 Any means to reduce the temperature difference inside and outside the refrigerator in this method and control system is not provided.

 A known method of controlling a thermoelectric refrigerator [2] using information about the temperature outside the refrigerator, at which the temperature outside the refrigerator (in the room where it is installed) is measured, and the temperature inside the refrigerator, their difference is determined, the threshold for switching the operating modes of the thermoelectric battery is set, if exceeded temperature differences of a given threshold translate the operation of the thermoelectric battery into maximum cooling capacity, and when this difference decreases below a predetermined threshold in their maximum coefficient of the thermopile.

 A known control system that implements this method [2] containing sensors inside and outside the refrigerator, a subtracting element, a control device with a threshold element, a switching device and a thermoelectric battery.

 In this method and system, in comparison with the above, the energy consumption is somewhat reduced due to the use of information about the temperature outside the refrigerator, since if it decreases (although within a small range of its change in a heated room), the thermal battery is switched to a large refrigerated mode coefficient.

 However, as in the previous method and system, the relay control principle is applied here, in which when the thermopile is switched off (or in the mode of maximum refrigeration coefficient) there is an excessive outflow of "cold" from the refrigerator, to make up for it when the thermopile is turned on (especially in the maximum cooling capacity) electricity is wasted unproductive. In both cases, the accuracy of maintaining the temperature in the refrigerator is low, in addition, they can only work at a positive ambient temperature.

A known method of controlling a refrigerator (heater) with a thermoelectric battery, in which the temperature inside the refrigerator (heater) is set, the current temperature is measured by sensors installed inside and outside the refrigerator (heater), the temperature differences between the set and measured inside the refrigerator (heater) are determined and between the external temperature and the set inside the refrigerator (heater), they form a control signal for the thermoelectric battery in the form of its supply voltage, heat (or cold) from the cold odnolnika (heater) is diverted through a thermoelectric battery [3]
A known control system [3] implements this method, comprising a series-connected temperature setpoint in the refrigerator (heater), a first adder, an amplifier-converter and a thermoelectric battery with external and internal radiators, temperature sensors installed inside and outside the refrigerator (heater), a second adder the inputs of which are connected to the outputs of the temperature setter and temperature sensor outside the refrigerator (heater), connected simultaneously to the input of the first adder.

 In this method and the control system that implements it, control is carried out according to the two-circuit principle. In the first (open) circuit, the control signal of the thermoelectric battery is formed by the difference between the external temperature and the set inside the refrigerator (heater), which monitors the change in external temperature. In the second (closed) circuit, the set value of the internal temperature of the refrigerator (heater) is stabilized, it is controlled by the difference between the set and measured internal temperatures by changing the thermal resistance between the surface of the thermoelectric battery and its internal radiator due to the corresponding movement of the radiator in the control process.

 In this method and system, the necessary control accuracy is provided, the operation of the refrigerator (heater) is allowed when the external temperature decreases below a predetermined internal temperature. In this case, the refrigerator switches to heating mode. In addition, they reduce energy consumption due to the linear principle of regulation (instead of the relay) and by monitoring the external temperature in the primary circuit in a relatively small range of changes in the external temperature, acceptable for a heated room.

 However, when regulating the internal temperature by changing the thermal resistance, unproductive energy losses of the thermal battery occur, and the energy consumption in the system remains significant. In addition, the design of the second circuit of the system is complex and unreliable.

 The objective of the present invention is to eliminate the disadvantages noted above, to reduce (minimize) the energy consumption in the system through the use of natural cold (heat) in a wide range of changes in external temperature while simplifying the design and increasing the accuracy of maintaining a given internal temperature.

 This goal is achieved by the fact that in the known method of controlling the refrigerator (heater), in which the temperature inside the refrigerator (heater) is set, the current temperature values are measured by sensors installed inside the refrigerator (heater) and outside it, the temperature differences between the set and measured inside the refrigerator are determined (heater) and between the external temperature and the set inside the refrigerator (heater), form a control signal for the thermoelectric battery in the form of its supply voltage, heat (or cold) from the refrigerator (heater) is diverted through the thermoelectric battery, according to the invention, the control signal of the thermoelectric battery is formed by the difference between the set and measured temperature inside the refrigerator (heater), in addition, in the control process, the signal arriving at the thermoelectric battery is measured, the temperature difference outside the refrigerator is determined from the measured signal ( heater) and specified inside it, achieved by the control system at the time of measuring the control signal, compare the received the difference with the same difference determined from the measured value of the external temperature, the control signal is corrected by the thermoelectric battery according to the comparison results, and heat (or cold) is removed from the refrigerator (heater) through the thermoelectric battery to the outdoor atmosphere, the temperature of which is measured by a sensor installed outside refrigerator (heater).

 This problem is also achieved by the fact that in the known method of controlling the refrigerator (heater), in which the temperature inside the refrigerator (heater) is set, the current temperature values are measured by sensors installed inside and outside the refrigerator (heater), the temperature difference between the set and measured inside is determined refrigerator (heater), form the control signal of the thermoelectric battery in the form of its supply voltage, heat (or cold) from the refrigerator (heater) is removed through the thermoelectric with it, according to the invention, the control signal of the thermoelectric battery is formed by the difference between the set and measured temperatures inside the refrigerator (heater), in addition, in the control process, the difference in the measured temperatures outside and inside the refrigerator (heater) is determined, the signal arriving at the thermoelectric battery is measured, the difference value is determined from the measured signal temperature outside the refrigerator (heater) and set inside it, achieved by the control system at the time of measuring the control signal, comp The obtained value of the difference with the difference of the measured temperatures outside and inside the refrigerator (heater) is calculated, the control signal is corrected by the thermoelectric battery according to the comparison results, and heat (or cold) is removed from the refrigerator (heater) through the thermoelectric battery to the outside atmosphere, the temperature of which is measured by a sensor installed outside the refrigerator (heater).

 The specified goal in the proposed control system is achieved by the fact that in the known system comprising a series-connected temperature setpoint in the refrigerator (heater), a first adder, an amplifier-converter and a thermoelectric battery with an external radiator, temperature sensors installed inside and outside the refrigerator (heater) , the second adder, the inputs of which are connected to the outputs of the temperature setter and the temperature sensor outside the refrigerator (heater), according to the invention, a scaling low hour is introduced a different filter, the input of which is connected to the output of the amplifier-converter, the outputs of the temperature sensor inside the refrigerator, the scaling low-pass filter and the second adder are connected to the corresponding inputs of the first adder, the refrigerator (heater) or part thereof containing an external thermoelectric battery radiator and a temperature sensor outside refrigerator (heater) are installed in contact with the outside atmosphere.

 The specified goal in the proposed control system is also achieved by the fact that in the known system comprising a series-connected temperature setpoint in the refrigerator (heater), a first adder, an amplifier-converter and a thermoelectric battery with an external radiator, temperature sensors installed inside the refrigerator (heater) and outside him, the second adder, the input of which is connected to the output of the temperature sensor outside the refrigerator (heater), according to the invention introduced a scaling low-pass filter, the input to the other is connected to the output of the refrigerator (heater), the scaling low-pass filter and the second adder are connected to the corresponding inputs of the first adder, the output of the temperature sensor inside the refrigerator (heater) is also connected to the corresponding input of the second adder, the refrigerator (heater) or part thereof containing an external radiator a thermoelectric battery and a temperature sensor outside the refrigerator (heater) are installed in contact with the outside atmosphere.

 The set of features that distinguish the claimed technical solution from the prototype, as applied to the purpose of the invention, is not known to the authors, and therefore, the proposed variants of the methods and control systems that implement them (united by a single technical design) satisfy the criteria of novelty and inventive step.

 The control method in General in cooling mode (at a positive ambient temperature) is as follows.

Set the temperature (Θ ₃ ) inside the refrigerator 4 with the help of a setpoint to the input of the system, measure the temperature inside the refrigerator (Θ _B ) and in the outside atmosphere (Θ _H ) with sensors 7 and 9. Using the appropriate summing elements 1, the difference (Θ ₃ -Θ _B ) of the set and measured inside the refrigerator temperature and the temperature difference (Θ _H- Θ ₃ ) measured in the outdoor atmosphere and set inside the refrigerator, or the temperature difference (Θ _H -Θ _B ), measured inside and outside the refrigerator. A control signal (σ) is generated in the converter amplifier 2 with a gain K, which is supplied to the input of the thermoelectric battery 3 in the form of a voltage or current of the corresponding polarity. The electrical energy in the thermoelectric battery 3 is converted with some delay, determined by the time constant ( _TB ), into the thermal energy corresponding to the signal σ, which is transmitted to the internal environment of the refrigerator with cooling capacity Q, determined by the parameters of the thermoelectric battery (see figure 2). The temperature in the refrigerator decreases and after a time determined by the time constant of the refrigerator T ₀ (depending on the specific heat of the refrigerator with the contents and its full thermal conductivity), it becomes equal to the set temperature (without taking into account the static error of the system). The heat accumulated by the refrigerator and its contents (Q ^* ), before turning on the system, is removed using the external radiator of the thermoelectric battery directly to the outdoor atmosphere.

 At a constant temperature of the outside atmosphere, in the process of lowering the temperature inside the refrigerator (due to the feedback signal), the control signal s proportionally decreases, the required cooling capacity Q decreases (see Fig. 2), and the refrigeration coefficient e of the thermal battery increases.

 In stationary mode, an equilibrium state is established in the system when the influx of thermal energy from the thermal battery is balanced by its leakage due to the thermal conductivity of the refrigerator.

In the control process, the control signal of the thermopile s is measured and determined using it using a scaling low-pass filter 5, the value of the temperature difference outside the refrigerator and set inside it, achieved by the control system at the time of measuring the control signal. The determination of this difference is carried out by converting the signal s in a scaling low-pass filter 5 with the transfer function W _Ф (Р) in the form of an aperiodic link К _Ф (Т _Ф P + 1), similar to the transfer function of the thermoelectric battery W _ТБ (Р) = К _ТБ / ( _{TB TB} +1).

The filter parameters are chosen so that K _F = K _TB • 1 / λ _o, and T _F = T _TB.
The difference obtained in the scaling low-pass filter 5 (ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ ) are compared in the summing element with the same temperature difference (ΔΘ _H-3 ), but obtained by measuring the temperature of the external atmosphere Θ _H or with the temperature difference inside and outside the refrigerator, determined by their measured values (ΔΘ _HB ). Based on the comparison results, the control signal σ is corrected.

In the steady-state control mode with a constant temperature of the external atmosphere and the absence of other disturbances, the signal difference ΔΘ _H-3 -ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ either ΔΘ _HB -ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ is zero, and the system remains in equilibrium, the control signal σ is not corrected, and the corresponding cooling capacity Q does not change.

When changing the temperature of the outside atmosphere Q _H , for example, its decrease, the difference ΔΘ _H-3 -ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ either ΔΘ _HB -ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ becomes negative because the change in signal ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ in the scaling low-pass filter 5 occurs with delay.

Signal Difference ΔΘ _H-3 -ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ either ΔΘ _HB -ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ with the opposite sign, it enters the system input and reduces (corrects) the control signal σ, cooling capacity of the thermopile (Q) by an appropriate value, increases the refrigeration coefficient (ε) of the thermopile, outpacing the response of the internal temperature sensor, thereby reducing energy consumption in the system and preventing it from being excessive spending.

 With an increase in the temperature of the outside atmosphere, the signal (σ) is corrected in the opposite direction, increasing the signal (σ), cooling capacity (Q), but decreasing the refrigeration coefficient (ε). In this case, of course, the power consumption of the system increases, but the outflow of “cold” accumulated in the refrigerator is not allowed due to its thermal conductivity, with the need for its subsequent replenishment. This also saves energy.

 At a negative ambient temperature, the control processes are similar to those described above, with the only difference being that the polarity of the signal σ changes and the thermopile generates “heat” rather than “cold”. The refrigerator becomes a heater.

 The choice of the option for generating a correction signal for the difference between the measured external temperature and the set or measured internal temperature depends on the required technical characteristics, parameters of the refrigerator (heater) and its operating conditions.

 The essence of the proposed technical solution is as follows. If you independently use the effect of reducing the temperature difference inside and outside the refrigerator (heater) by removing heat (cold) from the refrigerator (heater) directly to the outside atmosphere, when the temperature of the outside atmosphere is lower than the room temperature and when it is constant, energy consumption, as is obvious in the system decreases. However, with changes in the temperature of the outside atmosphere, in particular during its diurnal fluctuations, due to delays in the control loop, problems arise with maintaining the accuracy of temperature stabilization inside the refrigerator (heater) and, in addition, there is an excessive waste of electricity in the system during the fall of the outside temperature and leakage of "cold" ("heat") when it is increased, to make up for which electricity must also be expended. The total energy consumption in the system is increasing.

 Using information about changes in the temperature of the outside atmosphere to correct the control signal in conjunction with the removal of heat (cold) directly into the outside atmosphere based on the proposed method allows you to constantly keep the system in equilibrium, avoiding both excessive power consumption and leakage of cold (heat) from the refrigerator (heater). At the same time, the required accuracy of stabilization of the set temperature in the refrigerator (heater) is maintained, the required cooling capacity is reduced, the refrigeration coefficient of the thermal battery is increased, as a result, the energy consumption in the system is significantly reduced.

 Thus, the mathematical modeling of the average daily energy consumption in the proposed control system operated in the middle of Europe, taking into account daily and average monthly changes in atmospheric temperatures, showed that the energy consumption in this system is 3-4 times less compared to the known system operated in a heated indoors.

 The proposed control system (it also confirms the possibility of implementing the method) is depicted in figure 3.

The control system contains:
The temperature setpoint in the refrigerator (heater) 1, the first adder 2, the amplifier-converter 3, the thermoelectric battery 4 with an external radiator 5 and internal 6, a temperature sensor installed inside the refrigerator (heater) 7, the case of the refrigerator (heater) 8, temperature sensor 9 , the second adder 10, the scaling low-pass filter 11.

 The master 1, the first adder 2, the amplifier Converter 3 and the thermoelectric battery 4 are connected in series. The outputs of the sensors 7 and 9 are connected to one of the inputs of the first 2 and second 10 adders, respectively, the remaining inputs of the first adder 2 are connected to the output of the second adder 10 and to the output of the scaling low-pass filter 11. Either the output of the master 1 is connected to the second input of the second adder 10, or sensor output 7 (see dotted line). The case of the refrigerator (heater) or part thereof, in the wall of which is located the outer radiator 5 of the thermopile 4, and the temperature sensor 9 are installed in direct contact with the outside atmosphere.

In FIG. 3 are also indicated:
12 wall dividing the room and the refrigerator (heater) into internal and external parts;
s thermoelectric battery control signal;
Ds correction signal;
Q cooling capacity of a thermoelectric battery;
Q ^* heat discharged through an external radiator (cold);
Q _{s the} temperature set in the control system in the refrigerator (heater);
Θ _{B ′} , Θ _H temperature inside the refrigerator (heater) and the outside atmosphere, measured by the corresponding sensor;
ΔΘ _H-3 (ΔΘ _HB ) signal at the output of the second adder;
ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ signal at the output of the scaling low-pass filter.

 In FIG. 3, the dotted line indicates the relationship for the option of generating a correction signal for the difference between the measured internal and external temperatures. In this case, there is no connection between the second adder and the set temperature.

 The control system operates as follows.

Using the knob 1, the set temperature (Θ ₃ ) is introduced into the system inside the refrigerator. When the temperature of the outside atmosphere exceeds a predetermined temperature, the control system operates in cooling mode, the refrigerator (heater) acts as a refrigerator.

From the output of the first adder 2 (when the system is turned on), the signal equal to the sum of signals Θ ₃ -Θ _B + ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ -ΔΘ _H-3 or Θ ₃ -Θ _B + ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ -ΔΘ _HB . This signal is amplified and converted in the converter amplifier 3 into a control signal σ and, for example, in the form of an electric voltage or current of the corresponding polarity is supplied to the input of the thermoelectric battery 4. The control signal s is simultaneously supplied to the input of the scaling low-pass filter 11, made, for example, on an operational amplifier with an RC chain in the amplifier feedback (see the book by I.M.Tetelbaum, Yu.R. Schneider. 400 circuits for AVM. M. Energy, 1978, p. 24, fig. 1-1, p. .26, tab. 1-1).

Thermoelectric battery 5 converts electrical energy into cold energy with cooling capacity Q, the value of which exponentially increases from zero at the beginning of the transition process from the time constant T _{TB of} thermopile 5 to the value corresponding to the control signal s. Heat is removed from the refrigerator through the external radiator 5 to the outdoor atmosphere.

During cooling, if the temperature of the outside atmosphere (наруж _H ) is constant, the signal at the output of the second adder 10 remains unchanged, and the output of the scaling low-pass filter increases exponentially with the time constant T _TB (see the method description above) from zero at the initial time to the value corresponding to the temperature difference ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ which the system would have achieved with a constant signal σ in the steady state. A constant signal (ΔΘ _H-3 ) or (ΔΘ _HB ) from the output of the second adder 10 and an increasing signal (ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ ) from the output of the scaling low-pass filter 11, each with its own sign goes to the inputs of the first adder, where the sum of these signals is formed.

At a certain point in time, determined by the parameters of the system, the sum of these signals will become equal to zero, and at the output of the first adder 2, a signal will be generated corresponding to the difference Θ _3- т.е. _B , i.e. the correction circuit according to the temperature of the outside atmosphere turns off. At the end of the transition process, an equilibrium state is established in the system when the influx of cold from the thermopile 5 becomes equal to its outflow due to the thermal conductivity of the refrigerator.

When the temperature of the outside atmosphere (Θ _H ) changes, for example, when it decreases, the signal at the output of the second adder 10 (ΔΘ _H-3 ) or (ΔΘ _HB ) proportionally decreases, and at the output of the scaling low-pass filter 11 (ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ ), the signal delayed by the filter grows, but with a lower speed. Therefore, at the output of the first adder 2, a positive signal Δσ corresponding to the difference ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ -ΔΘ _H-3 or ΔΘ $\genfrac{}{}{0ex}{}{\text{*}}{\text{H-3}}$ -ΔΘ _HB , which corrects the control signal σ in the direction of decrease. The control system "monitors" the change in external temperature, maintaining the state of the system in "equilibrium" when the influx of cold from the thermopile is balanced by its outflow due to the thermal conductivity of the refrigerator.

 In the case of an increase in the temperature of the outside atmosphere, the dynamics of the processes are similar to the case considered. When the refrigerator is operating at a negative temperature in the outside atmosphere, the polarity of the voltage (or current) supplied to the thermoelectric battery changes, and it goes into heating mode, the refrigerator becomes a heater. Otherwise, the dynamics of the process in heating mode in the control system remains the same.

 Other features of the proposed control system were noted in the description of the method.
