Correspondingly, the cooling flow of air conditioner is as follows：
During refrigeration, compressor 1 discharges the refrigerant of high pressure gaseous, and refrigerant flows through four-way valve 2 to outdoor heat exchanger 3, led to
The rotation of outdoor fan 4 is crossed, will be changed as the air of cooling medium and the refrigerant of the high temperature high-pressure gaseous of outdoor heat exchanger 3
Heat, refrigerant is cooled to the refrigerant of middle temperature high-pressure liquid, and refrigerant flows through the first filter 5 and carries out contaminant filter, cold after filtering
Matchmaker is throttled by electric expansion valve 6, becomes the refrigerant of low-temp low-pressure vehicle repair major, and refrigerant passes through the second filter 7, first
Get in and change by liquid pipe (not shown in Fig. 2) and the corresponding refrigerant import magnetic valve (not shown in Fig. 2) of refrigeration mode afterwards
In hot device 9, by the rotation of indoor fan 10, by indoor hot-air and low-temp low-pressure vehicle repair major in indoor heat exchanger 9
Refrigerant is exchanged heat so that indoor hot air temperature declines, while successively passing through after refrigerant heat absorption evaporation in indoor heat exchanger 9
The corresponding refrigerant exit magnetic valve (not shown in Fig. 2) of refrigeration mode and tracheae (not shown in Fig. 2) outflow indoor heat exchanger 9,
Refrigerant enters vapour liquid separator 12 by four-way valve 2 again, returns compressor 1 and is circulated.
Specifically, during refrigeration, the refrigerant of low-temp low-pressure vehicle repair major successively passes through liquid pipe and the corresponding refrigerant of refrigeration mode
Inlet solenoid valve gets in heat exchanger 9, flows through the refrigeration distributor (not shown in Fig. 2) of indoor heat exchanger 9, and freeze distributor
Liquid coolant is distributed into the refrigerating capillary (not shown in Fig. 2) of indoor heat exchanger 9, after liquid coolant is by refrigerating capillary
Enter back into indoor heat exchanger 9, by the rotation of indoor fan 10, by indoor hot-air and low temperature in indoor heat exchanger 9

When heating, compressor 1 discharges the refrigerant of high pressure gaseous, and refrigerant flows through four-way valve 2, successively passes through tracheae and system
The corresponding refrigerant import magnetic valve (not shown in Fig. 2) of heat pattern, gets in heat exchanger 9, passes through turning for indoor fan 10
It is dynamic, indoor cold air and the refrigerant of the high temperature high-pressure gaseous of indoor heat exchanger 9 are exchanged heat so that cold air inside temperature
Rise, while being cooled to the refrigerant of middle temperature high-pressure liquid in indoor heat exchanger 9 after refrigerant radiating, refrigerant successively flows through heating mode
Corresponding refrigerant exit magnetic valve (not shown in Fig. 2) and liquid pipe outflow indoor heat exchanger 9, then carried out by the second filter 7
Contaminant filter, the refrigerant after filtering is throttled by electric expansion valve 6, becomes the refrigerant of low-temp low-pressure vehicle repair major, cold
Matchmaker passes through the first filter 5, into outdoor heat exchanger 3, then enters vapour liquid separator 12 by four-way valve 2, returns compression
Machine is circulated.
Specifically, when heating, the refrigerant of high pressure gaseous successively passes through tracheae and the corresponding refrigerant import of heating mode
Magnetic valve gets in heat exchanger 9, and flow therethrough into indoor heat exchanger 9 heats discharge (not shown in Fig. 2), and refrigerant is allocated
Got in into several streams in heat exchanger 9, by the rotation of indoor fan 10, by indoor cold air and indoor heat exchanger 9
The refrigerant of high temperature high-pressure gaseous is exchanged heat so that cold air inside temperature rises, while refrigerant radiates in indoor heat exchanger 9
It is cooled to the refrigerant of middle temperature high-pressure liquid afterwards, what refrigerant passed through indoor heat exchanger 9 heats capillary (not shown in Fig. 2), enters
Enter heating in distributor (not shown in Fig. 2) for indoor heat exchanger 9, then after the corresponding refrigerant exit magnetic valve of heating mode
Indoor heat exchanger 9 is flowed out from liquid pipe.
It can be seen that, when heating, refrigerant (temperature probably has 70 DEG C) and the temperature after heat exchange of the high pressure gaseous that compressor 1 is discharged
The higher room air (temperature probably has 40 DEG C) of degree is exchanged heat, and after cooling the relatively low refrigerant of temperature (temperature probably has 42
DEG C) exchanged heat with the room air (temperature probably has 20 DEG C) without heat exchange, logarithmic mean temperature difference (LMTD) is improved, improves and changes
The thermal efficiency, so as to improve the ability and efficiency of complete machine.
