Description

FIELD OF THE INVENTION [0001] The present invention relates to a system and a method for preventing condensation using IoT combined heat lines,

Disclosed herein are systems and methods for preventing condensation, and more particularly, systems and methods for preventing condensation using IoT coupled heat lines.

Dew condensation refers to a kind of wet state in which the temperature of the air falls below the dew point temperature to become a saturated state that can no longer contain water vapor, and the extra water vapor becomes water droplets. The causes of condensation include indoor and outdoor temperature differences, excessive humidity in the room, and lack of ventilation. This condensation occurs at the dew point temperature determined by temperature and humidity, and humidity plays an important role in health.

Methods for maintaining adequate room humidity include the construction of mechanical forced ventilation, the use of electronic products such as humidifiers and dehumidifiers, and the use of chemicals that require periodic replacement, such as moisture removal agents.

On the other hand, when indoor humidity is high, dew condensation occurs on the outer wall of the housing structure. When there is a part where the insulation is not continuous on the outer wall of the house structure, floor, roof, etc., or where there is a part where the thermal conductivity is large at the corner part of the outer wall of the building, (Thermal bridge).

Thermal bridging is the part of the structure that causes heat exchange to lower the overall insulation value of the structure due to its high thermal conductivity. It is also referred to as "cold bridge" in terms of heat loss due to the thermally weak parts of these structures.

The rim of the building, the uppermost slab roof, and the protruding part of the balcony are vulnerable to continuous heat insulation, which is difficult to maintain continuously. Condensation may occur due to heat bridging due to heat entering and leaving. And the like.

Thus, in the case of condensation occurring outside the building, it is very difficult to prevent condensation from forced ventilation equipment, ordinary humidification and dehumidification electronic products and chemical products.

Accordingly, a new method for preventing condensation occurring on the outside of a building or the like needs to be devised.

FIG. 2 is a block diagram of a hot wire 1 and a hot wire operating device 100, which are components of a dew condensation preventing system using an IoT-coupled hot wire according to an embodiment of the present invention.

The heating wire (1) is a heating cable called a constant temperature wire. Unlike the conventional heating cable, the heating wire is heated by plastic semiconductors containing carbon, coefficient.

The PTC characteristic is a kind of natural phenomenon. It shows a phenomenon in which the calorific value is automatically increased or decreased as the ambient temperature changes. The constant temperature wire is a special heating element having a continuous parallel circuit structure using a conductive polymer. Self-regulating heating cable designed to automatically increase or decrease the amount of heat generated by controlling the temperature.

The constant-temperature electric wire is a self-regulated heater developed by applying the PTC principle. It has the advantage of minimizing the electric consumption because the heat is much colder in cold weather and less heat in colder weather.

If heat is generated by the hot-wire operating part 170 of the hot-wire operating device 100 in a state where the hot-wire 1 is wrapped around or attached to a site where thermal cross-linking occurs, the thermal cross- .

In addition to residential areas such as houses, condensation often occurs in outdoor facilities such as warehouses, indoor swimming pools, farms, cages, etc., and ships operated in marine environments. Even in this environment, the IoT- Condensation can be prevented by arranging it appropriately.

The hot wire operating device 100 is a component that controls the operation of the hot wire 1 by supplying power to the plurality of hot wires 1 and transmits the operation state information of each hot wire 1 to the hot wire operating device 200.

In the case of a structure in which a plurality of heat bridging occurrence sites exist, a hot wire 1 is disposed at each heat bridging occurrence site, and one heat wire operating device 100 is provided for a plurality of hot wires to control the operation of each hot wire 1. [ . In the case of a large structure or a complex structure, one or more hot-wire operating devices 100 are required. Each hot-wire operating device 100 controls the operation of a plurality of hot-wire lines 1, 200).

The power supply unit 110 includes an AC-DC converter that converts AC power into AC power and a fuse that cuts off an overcurrent. The power supply unit 110 uses an AC power source 100, and applies the generated at least one driving voltage to the corresponding component. Thus, the operation of the hot-wire operating device 100 can be performed. The power source AC applied to the power source unit 110 is preferably 80 V to 240 V and a commercial power source having a frequency of 50 Hz or 60 Hz.

The power supply unit 110 includes a temperature switch (not shown) which is a bimetal switch that is turned on or off according to the ambient temperature. The temperature switch maintains the on state when the ambient temperature is below the set temperature and remains off when the ambient temperature exceeds the set temperature. The size of the set temperature can be changed if necessary.

When the temperature switch is maintained in the ON state, the external power source AC is supplied to the power source unit 110 through the temperature switch to start the operation of the hot-wire apparatus 100. When the temperature switch is kept in the OFF state, The external power source AC supplied to the power source unit 110 is not applied to the power source unit 110 but is interrupted by the temperature switch to stop the operation of the hot-

The operation of the power source unit 110 is controlled by the operation of the temperature switch so that the power of the power source unit 110 is automatically shut off when the ambient temperature exceeds the set temperature, The application of the voltage is interrupted, so that a waste of standby power consumed in each component of the hot-wire device 100 is prevented, and unnecessary power consumption in the hot-wire device 100 is prevented.

These temperature switches can be omitted as needed. When the temperature switch is omitted, the power supply AC is supplied to the power supply unit 110 at all times, and the heating wire control unit 150 supplies the power to the heating wire control unit 170 through the heating wire operating unit 170 according to the temperature sensing signal output from the temperature sensing unit 120 And controls the operation of the hot wire (1).

The temperature sensing unit 120 is built in the hot wire operating device 100 and outputs a temperature sensing signal to the hot wire control unit 150. When the external temperature sensing unit (not shown) is additionally provided, the temperature sensing unit is intermittently disposed along the heating wire 1 in the structure in which the heating wire 1 is installed, and outputs a temperature sensing signal to the heating wire control unit 150.

Examples of the temperature sensing unit include a thermocouple, a temperature measuring resistor, a thermistor (NTC, PTC, CTR), a metal thermometer, a thermistor thermally sensitive ferrite, Ultrasonic sensors, and optical fiber sensors.

The humidity sensing unit 130 is built in the hot-wire operating device 100 and outputs a humidity sensing signal to the hot-wire control unit 1150. In addition, when an external humidity sensing unit (not shown) is provided, the humidity sensing unit is disposed around the temperature sensing unit 120 of the structure in which the heat sink 1 is installed, and outputs a humidity sensing signal to the heat line controller 150.

The GPS 140 collects position information of the hot-wire operating device 100. When a plurality of hot-wire operating devices 100 operate in conjunction with the hot-wire operating device 200, the hot-wire operating device 200 generates hot- The operation of the operating device 100 can be controlled.

The heating wire control unit 150 starts operation when a driving voltage required for operation is applied by the power supply unit 110 and receives a temperature sensing signal from the temperature sensing unit 120 and receives a humidity sensing signal from the humidity sensing unit 130 do.

Next, the heat ray controller 150 determines whether or not condensation occurs from the temperature value and the humidity value included in the temperature detection signal and the humidity detection signal, using the dew point calculation table stored in the storage unit 160 or using the built-in dew point calculation algorithm.

The storage unit 160 stores an identification number (ID) of the hot-wire operating device 100 belonging to itself as a memory, a temperature value sensed by the temperature sensing unit 120, It is necessary to perform the operation of the hot-wire operating device 100 such as the detected humidity value, at least one set temperature, at least one set humidity, a dew point calculation table for determining whether or not condensation exists, a dew point calculation algorithm, Data and data generated during operation are stored.

The hot wire operating part 170 may be composed of a switching element or a relay such as a triac (triode alternating current switch).

When the hot wire operating part 170 is made of triac, the risk of fire or explosion is prevented as compared with the case of using the relay. When a relay is used, there is a possibility that a flame may be generated in the operation of a physical switching contact of the relay, so that when the combustion material of a boiler or the like in which the hot wire operating part 170 is installed is a material having good flammability such as gas, May cause fire or explosion.

However, when the hot wire operating part 170 is a triac, which is a semiconductor element, there is no possibility of occurrence of such flame, so that the risk of a safety accident is solved. In addition, since the phase control using the triac is performed, abrupt current flow to the hot wire 1 is prevented, and the service life of the hot wire 1 also increases.

The control terminal of the hot wire operating part 170 is connected to the hot wire control part 150 and the output terminal is connected to the hot wire 1 and the input terminal is connected to the driving voltage generated by the power supply part 110. [

The operation of the hot wire operating part 170 is as follows.

First, when the heat line control unit 150 determines that the surrounding environment is in a condensation state, a control signal is output to the heat line operation unit 170 so that current flows to the heat line 1 so that the heat operation of the heat line 1 is performed do. At this time, the heat-ray control unit 150 controls the magnitude of the current applied to the hot-wire operation unit 170, the magnitude of the voltage, or the turn-on time based on the temperature value sensed by the temperature sensing unit 120.

When a current flows into the hot wire 1 by the operation of the hot wire operating part 170, the current value flowing through the hot wire 1 is fed back to the hot wire controlling part 150. The hot wire control unit 150 appropriately controls the hot wire operating unit 170 using the feedback current value and determines whether or not the hot wire 1 is disconnected based on the resistance value of the hot wire 1. [

Alternatively, when a current sensor is provided in the hot-wire operating unit 170, the current flowing through the hot-wire 1 can be checked in real time using the current sensor, the current consumption can be measured, can do.

The determination of the operating state of the heating wire 1 is performed by the heating wire control unit 150, and the determination result is stored in the storage unit 160. [
