Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Compressor 1 outlet is connected with a end of four-way change-over valve 2, and the air inlet pipe of compressor 1 is connected with the b end of four-way change-over valve 2 after connecting device for drying and filtering 6; The c end of four-way change-over valve 2 connects indoor heat exchanger 3, d end junction chamber external heat exchanger 5; Between indoor heat exchanger 3 and outdoor heat exchanger 5, be connected heating power expansion valve 4; From compressor 1 blast pipe, drawing tube connector is connected with capillary 11 one end; Capillary 11 other ends connect 7 imports of antifrost pipe; Capillary 11 is imported and exported two ends bypass the 3rd magnetic valve 10; 7 outlets of antifrost pipe are divided into two-way, connect respectively the first magnetic valve 8 and the second magnetic valve 9; The first magnetic valve 8 outlets connect between indoor heat exchanger 3 and heating power expansion valve 4; The second magnetic valve 9 outlets connect between outdoor heat exchanger 5 and heating power expansion valve 4.
Specific works process:
1, when refrigerating operaton, the first magnetic valve 8, the 3rd magnetic valve 10 cuts out, the second magnetic valve 9 is opened, the a pipe of four-way change-over valve 2 communicates with d pipe, c pipe communicates with b pipe, enter outdoor heat exchanger 5 from compressor 1 most of higher pressure refrigerant gas out by four-way change-over valve 2, condensation of refrigerant heat exchange is liquid, refrigerant liquid is through heating power expansion valve 4 throttlings, become the refrigerant liquid of low-temp low-pressure laggard enter indoor heat exchanger 3, heat of vaporization in absorption chamber, low-temperature low-pressure refrigerant gas after evaporation is through four-way change-over valve 2, device for drying and filtering 6 is got back to compressor.
When refrigeration main road circularly cooling, blast pipe bypass out part high-temperature high-pressure refrigerant gas, through capillary 11 and antifrost pipe 7, is cooled to refrigerant liquid, by the second magnetic valve 9, before inflow expansion valve 4, this part bypass cold-producing medium participates in kind of refrigeration cycle.Two parts cold-producing medium participates in kind of refrigeration cycle simultaneously, improves unit efficiency.
2, when heating operation, the first magnetic valve 8, the second magnetic valve 9, the 3rd magnetic valve 10 Close Alls, the a pipe of four-way change-over valve 2 communicates with c pipe, b pipe communicates with d pipe, enter indoor heat exchanger 3 from compressor 1 higher pressure refrigerant gas out by four-way change-over valve 2, after condensing heat-exchange, refrigerant liquid is by heating power expansion valve 4 throttlings, become low-temperature low-pressure refrigerant liquid, enter outdoor evaporimeter 5 cold-producing mediums and from atmosphere, absorb heat of vaporization, low-temperature low-pressure refrigerant gas after evaporation is through four-way change-over valve 2, device for drying and filtering 6 is got back to compressor, complete and heat circulation.
3, when Defrost operation, the first magnetic valve 8, the 3rd magnetic valve 10 is opened, the second magnetic valve 9 cuts out, the a pipe of four-way change-over valve 2 communicates with d pipe, c pipe communicates with b pipe, enter outdoor heat exchanger 5 from compressor 1 most of higher pressure refrigerant gas out by four-way change-over valve 2, remove the frost of outdoor heat exchanger cohesion by warm refrigerant, condensation of refrigerant heat exchange is liquid, refrigerant liquid is through heating power expansion valve 4 throttlings, become the refrigerant liquid of low-temp low-pressure laggard enter indoor heat exchanger 3, low-temperature low-pressure refrigerant gas after evaporation is through four-way change-over valve 2, device for drying and filtering 6 is got back to compressor.
Exhaust bypass out part high-temperature high-pressure refrigerant gas directly passes into antifrost pipe 7 and carries out Defrost operation after the 3rd magnetic valve 10, is cooled to the cold-producing medium of liquid by the first magnetic valve 8, imports circulation main road.
4, when Defrost operation finishes, the first magnetic valve 8, the 3rd magnetic valve 10 continue to open, the a pipe of four-way change-over valve 2 communicates with c pipe, b pipe communicates with d pipe, enter indoor heat exchanger 3 from compressor 1 higher pressure refrigerant gas out by four-way change-over valve 2, after condensing heat-exchange, refrigerant liquid is by heating power expansion valve 4 throttlings, become low-temperature low-pressure refrigerant liquid, enter outdoor evaporimeter 5 cold-producing mediums and from atmosphere, absorb heat of vaporization, low-temperature low-pressure refrigerant gas after evaporation is got back to compressor through four-way change-over valve, device for drying and filtering, continues to heat circulation.
Exhaust bypass out part high-temperature high-pressure refrigerant gas directly passes into antifrost pipe 7 and carries out Defrost operation after the 3rd magnetic valve 10, and the cold-producing medium that is cooled to liquid flows into before expansion valve 4 by the first magnetic valve 8, imports circulation main road.This section of time remaining 5-10 minute.
