Heating and air conditioner 100 according to embodiments of the present invention being described in detail below with reference to Fig. 1, this heating and air conditioner 100 has refrigeration mode and heating mode. Specifically, heating and air conditioner 100 can be transducer air conditioning.
As it is shown in figure 1, heating and air conditioner 100 according to embodiments of the present invention, including: compressor 1, commutation assembly 2, outdoor heat exchanger 3, subcooler 4, indoor heat exchanger 5, restricting element 6 and the radiating subassembly 7 for electronic control module is dispelled the heat. Wherein compressor 1 is provided with air vent a and gas returning port b, it is to be understood that the structure of compressor 1 and operation principle have been prior art, are not just described in detail here.
Commutation assembly 2 includes the first valve port c to the 4th valve port f, one of them connection in first valve port c and the second valve port d and the 3rd valve port e, another connection in 4th valve port f and the second valve port d and the 3rd valve port e, the first valve port c is connected with air vent a, and the 4th valve port f is connected with gas returning port b. It is to say, then the 4th valve port f and the three valve port e connection when the first valve port c and the second valve port d connects, then the 4th valve port f and the second valve port d connection when the first valve port c and the three valve port e connection. Preferably, commutation assembly 2 is cross valve. As long as of course, it should be understood that commutation assembly 2 may be formed as other structures and has the first valve port c to the 4th valve port f and can carry out commutating.
First end of outdoor heat exchanger 3 and the second valve port d are connected. Subcooler 4 includes the first refrigerant passage 4a and the second refrigerant passage 4b of mutual heat exchange, and first end of the first refrigerant passage 4a is connected with the second end of outdoor heat exchanger 3, and first end of the second refrigerant passage 4b and the 3rd valve port e are connected. The two ends of indoor heat exchanger 5 are connected with second end of the second refrigerant passage 4b and the first end of restricting element 6 respectively, specifically, restricting element 6 plays the effect of reducing pressure by regulating flow, and alternatively, restricting element 6 is the combination of capillary tube, electric expansion valve, heating power expansion valve or said elements.
Radiating subassembly 7 is connected between the second end and second end of restricting element 6 of the first refrigerant passage 4a, the running status that electronic control module is connected with commutation assembly 2 and compressor 1 to control commutation assembly 2 and compressor 1.
When heating and air conditioner 100 is in refrigeration mode, the first valve port c and the second valve port d connection and the 4th valve port f and the three valve port e connect. as illustrated by the arrows in fig. 1, the coolant discharged from compressor 1 is drained into outdoor heat exchanger 3 by the first valve port c and the second valve port d and carries out condensation heat radiation, the coolant that heat exchanger 3 is discharged outdoor is drained in the first refrigerant passage 4a, it is drained into radiating subassembly 7 so that electronic control module is dispelled the heat from the first refrigerant passage 4a coolant discharged, it is drained into after the reducing pressure by regulating flow of restricting element 6 indoor heat exchanger 5 from the coolant of radiating subassembly 7 discharge and is evaporated heat absorption, the coolant that heat exchanger 5 is discharged indoor is drained in the second refrigerant passage 4b, it is expelled back into compressor 1 from the second refrigerant passage 4b coolant discharged through the 3rd valve port e and the four valve port f.
Owing to the temperature of the coolant in the second refrigerant passage 4b is lower than the temperature of the coolant in the first refrigerant passage 4a, therefore the first refrigerant passage 4a and the second refrigerant passage 4b carries out heat exchange, make the coolant in the first refrigerant passage 4a supercool, the supercool loss making coolant pass through not result in when radiating subassembly 7 cools down electronic control module refrigerating capacity.
Simultaneously because coolant in the first refrigerant passage 4a is through the cooling of the second refrigerant passage 4b, ensure that the temperature of the coolant entered in radiating subassembly 7 can effectively reduce the temperature of electronic control module, can also effectively cool down even if electronic control module temperature is higher.
Heating and air conditioner 100 according to embodiments of the present invention, the coolant that heat exchanger 3 outdoor is discharged by the coolant that heat exchanger 5 is discharged indoor is adopted to carry out supercool during refrigeration, it is possible not only to the loss avoiding causing refrigerating capacity during cooling electronic control module, the temperature of electronic control module can also be effectively reduced, simultaneously simple in construction, reasonable in design, cost is low.
In the concrete example of the present invention, as it is shown in figure 1, heating and air conditioner 100 also includes outdoor fan 10, outdoor fan 10 is located at the side of outdoor heat exchanger 3 to direct the air to outdoor heat exchanger 3, such that it is able to improve the heat transfer effect of outdoor heat exchanger 3.

Specifically, when controlling valve 8 and opening, corresponding heat dissipation channel 7a and the first refrigerant passage 4a connection, it is to say, by the unlatching number controlling valve 8, it is possible to control to carry out the quantity of the heat dissipation channel 7a of heat exchange with electronic control module, such that it is able to control the radiating subassembly 7 radiating effect to electronic control module, can meet the radiating requirements of different condition, and then the radiating effect of the electronic control module that heating temp is higher can be effectively ensured, electronic control module can also be avoided simultaneously to produce dew condensation phenomenon. Preferably, controlling valve 8 is electromagnetic valve.
In further embodiment of the present invention, heating and air conditioner 100 also includes temperature-detecting device for detecting electronic control module temperature (not shown go out), and electronic control module is connected with temperature-detecting device and controls the unlatching number of multiple control valves 8 with the testing result according to temperature-detecting device. Specifically, the temperature of electronic control module is more high, and the number controlling valve 8 of unlatching is more many, such that it is able to be effectively ensured the radiating effect of the electronic control module that heating temp is higher, electronic control module can also be avoided to produce dew condensation phenomenon simultaneously. It is appreciated of course that, electronic control module can also control the unlatching number of valve 8 according to other testing conditions, for instance can detect outdoor environment temperature, control the unlatching number of valve 8 according to outdoor environment temperature, outdoor environment temperature is more low, and the unlatching number controlling valve 8 is more few; Or the unlatching number of valve 8 can also be controlled according to the temperature of outdoor environment temperature and electronic control module.
In some specific embodiments of the present invention, presetting three temperature ranges in electronic control module, controlling valve 8 is three, and electronic control module controls the unlatching number of valve 8 according to the temperature range that the testing result of temperature-detecting device is corresponding. specifically, in electronic control module, preset first temperature is interval, second temperature range, 3rd temperature range, the temperature of temperature < the 3rd temperature range of temperature < second temperature range of the first temperature range, when the result of temperature-detecting device detection is positioned at the first temperature range, only control one of them control valve 8 to open, when the result that temperature-detecting device detects is positioned at the second temperature range, control two of which control valve 8 to open, when the result of temperature-detecting device detection is positioned at three temperature ranges, control three control valves 8 to be all turned on. such that it is able to effectively ensure the radiating effect to electronic control module, electronic control module can also be avoided to produce dew condensation phenomenon simultaneously.
Wherein it is understood that the actual temp scope of three temperature ranges can be defined according to practical situation. Such as the first temperature range can be 50 DEG C～60 DEG C, and the second temperature range can be 60 DEG C～70 DEG C, and the 3rd temperature range can be 70 DEG C～85 DEG C. When the temperature of electronic control module reaches more than 70 DEG C, control three control valves 8 to open simultaneously and cool down electronic control module, when the temperature of electronic control module is lower than 60 DEG C, cause electronic control module that condensation occurs to prevent electronic control module sub-cooled, control one of them control valve 8 and open.
When the coolant entered in heat exchanger is the mixing coolant including gaseous coolant and liquid refrigerants, owing to gaseous coolant is not involved in heat exchange but takies the space of heat exchanger, the heat transfer effect of heat exchanger can be reduced, therefore as shown in Figure 1, in some embodiments of the invention, heating and air conditioner 100 also includes fluid reservoir 9, fluid reservoir 9 is provided with first interface n and the second interface m, first interface n is positioned at the top of fluid reservoir 9, second interface m is positioned at the bottom of fluid reservoir 9, first interface n and the second valve port d is connected, and the second interface m is connected with the first end of outdoor heat exchanger 3.
Specifically, fluid reservoir 9 can play the effect of gas-liquid separation, when heating and air conditioner 100 is in refrigeration mode, enter into from the second valve port d coolant discharged and in fluid reservoir 9, carry out gas-liquid separation, liquid coolant escapes and enter from the second interface m and carries out heat exchange outdoor heat exchanger 3, such that it is able to reduce the amount of the gaseous coolant entered in outdoor heat exchanger 3, and then the ratio of the coolant being not involved in heat exchange can be reduced, improve the heat transfer effect of outdoor heat exchanger 3. When heating and air conditioner 100 is in heating mode, the coolant that heat exchanger 3 is discharged outdoor is drained in fluid reservoir 9 and carries out gas-liquid separation, gaseous coolant is discharged from first interface n and is passed through commutation assembly 2 and is drained into compressor 1, such that it is able to avoid to a certain extent, because liquid refrigerants enters compressor 1, liquid hit phenomenon occurs.

Owing to the temperature of the coolant in the second refrigerant passage 4b is lower than the temperature of the coolant in the first refrigerant passage 4a, therefore the first refrigerant passage 4a and the second refrigerant passage 4b carries out heat exchange, make the coolant in the first refrigerant passage 4a supercool, the supercool loss making coolant pass through not result in when radiating subassembly 7 cools down electronic control module refrigerating capacity.
