Description
Technical field
The utility model relates to a kind of low-temperature water heating device, relates in particular to the structure of this low-temperature water heating device.
Background technology
As seen from Figure 1: common water-heater system mainly is made up of evaporimeter 1, compressor 2, condenser 3,4 four parts of choke valve, also comprises: be connected flow separator 6 between reservoir 5, compressor and the evaporimeter between choke valve and the condenser, be connected between compressor and the condenser and the cross valve 7 between the flow separator evaporimeter and be connected pipeline between these above-mentioned parts.
When system was individual system, when temperature is low to moderate about-10 ℃, the evaporability of system descended, cause the pressure at expulsion of compressor to rise, pressure of inspiration(Pi) descends, and compression ratio increases, exceed the range of operation of compressor regulation this moment, damaged compressor easily, made unit damage.
Therefore the safe range of the operation of hot water machine of the prior art is generally all more than-5 ℃, and better unit also just can be low to moderate-10 ℃.Because these restrictions, common hot water machine all can only be on the south the Changjiang river the area use, and in East China one band, the efficient of hot water machine is poor in the time of winter, efficiency all can't reach 2.0, becomes a power consumption rich and influential family in winter again, brings big load again for the original nervous energy.
Summary of the invention
The utility model technical issues that need to address have provided a kind of ultralow temperature water heater that can be used for-25 ℃, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: first system; Described first system comprises: evaporimeter, first compressor, first condenser, first throttle valve, be connected first flow separator between reservoir, compressor and the evaporimeter between choke valve and the condenser, be connected between compressor and the condenser and the cross valve between the flow separator evaporimeter; Choke valve is between reservoir and evaporimeter; Also comprise: second system and be connected first system and second system between fluorine-fluorine plate-type heat exchanger; Described second system comprises: second compressor, second condenser, second choke valve and second flow separator; Fluorine-fluorine plate-type heat exchanger is connected between first condenser and reservoir and second choke valve and second flow separator; Second flow separator links to each other with second choke valve through second condenser by second compressor.
Compared with prior art, the beneficial effects of the utility model are: make the area of unit to the north of the Changjiang river also can adapt to use, and improved the Energy Efficiency Ratio of hot water machine when low temperature, save the energy, thereby satisfied the requirement of the energy-saving and emission-reduction of country's proposition now.
Description of drawings
Fig. 1 is a low-temperature water heating device structural representation in the prior art;
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: first system; Described first system comprises: evaporimeter 1, first compressor 2, first condenser 3, first throttle valve 4, be connected first flow separator 6 between reservoir 5, compressor and the evaporimeter between choke valve and the condenser, be connected to the cross valve 7 between compressor and the condenser and between the flow separator evaporimeter; Choke valve 4 is between reservoir and evaporimeter; Also comprise: second system and be connected first system and second system between fluorine-fluorine plate-type heat exchanger 8; Described second system comprises: second compressor 20, second condenser 30, second choke valve 40 and second flow separator 60; Fluorine-fluorine plate-type heat exchanger 8 is connected between first condenser 3 and reservoir 5 and second choke valve 40 and second flow separator 60; Second flow separator 60 links to each other with second choke valve 40 through second condenser 30 by second compressor 20.
First system is identical with common water-heating machine system in the utility model, all is made up of evaporimeter, compressor, condenser, four parts of choke valve and the copper pipe that is connected.Different with common hot water machine is to have increased by one second system, comprises compressor No. 2, No. 2 condensers, No. 2 choke valves and fluorine-fluorine plate-type heat exchanger and the pipeline that is connected.
The new parts that add all are prior aries in the utility model.
Ultralow temperature (25 ℃) water heater is by using two cover systems, use the first conventional service system when being higher than-5 ℃, this moment first service system compressor start, enter condenser by cross valve, carry out heat exchange with the water that enters condenser and produce hot water, through throttling, enter evaporimeter and air heat exchange, return compressor.At this moment the Energy Efficiency Ratio of air-conditioning is more than 2.5, and when being lower than-5 ℃ to-25 ℃, start first system and second system simultaneously, switch in the water route, this moment, first system was as thermal source, condenser is no longer produced hot water, but allow the condenser of fluorine-fluorine plate-type heat exchanger as first system, second compressor start of second system, enter second condenser and water and carry out heat exchange and produce hot water, enter fluorine-fluorine plate-type heat exchanger through second choke valve again, this moment, fluorine-fluorine plate-type heat exchanger was the evaporimeter of second system, carry out heat exchange with first system, return compressor.First system that so just guaranteed when low temperature condensation temperature and evaporating temperature in safety and efficient range of operation, and first system is because the decline of pressure at expulsion, the compression ratio of system descends, can not damage compressor, thereby make that complete machine can safe operation, realized in low temperature, can also normally producing hot water, and efficiency still maintains more than 2.0, realized energy-conservation greatly.
