Cold-producing medium is not by abundant liquefaction when the refrigeration to the heat pump air conditioner of prior art, and refrigerating efficiency is poor; Be prone to frosting when heating, the problem that running is ended occurs heating, the condenser of the utility model is used for heat pump air conditioner.
Fig. 7 is the loop diagram of the heat pump air conditioner cooling operation of the utility model specific embodiment; Fig. 8 is the loop diagram that the heat pump air conditioner of the utility model specific embodiment heats running; With reference to figure 7 and Fig. 8, the heat pump air conditioner of the utility model comprises: compressor 10; Cross valve 11 is connected with compressor 10 through pipeline 41,48; Off-premises station heat exchanger 12 and heat exchanger indoor unit 13 are connected with cross valve 11 through pipeline 42,47 respectively; Refrigeration decompressor 15, one ends that only when refrigeration, start are connected with heat exchanger indoor unit 13 through pipeline 46; Decompressor 14, one ends that heat that only when heating, start are connected with off-premises station heat exchanger 12 through pipeline 43; Condenser 30, the first interfaces are connected with the other end that heats decompressor 14 through pipeline 44, and second interface is connected through the other end of pipeline 45 with refrigeration decompressor 15.First interface of condenser 30, second interface are first interface, second interface of condenser pipe 31.
The decompressor 14 that heats when heating is included in configuration first check-valves 17 arranged side by side and first capillary 16 on pipeline 43 and the pipeline 44.First check-valves 17 is closed condition for desire from the cold-producing medium that pipeline 44 flows to pipeline 43.When shown in Figure 8 heating turned round, in the refrigeration decompressor 15 when refrigeration, second check-valves 19 was opening.Therefore, the cold-producing medium that heats when running flows out from pipeline 46, is not through second capillary 18 but flows to pipeline 45 through second check-valves 19, can not be depressurized.Be specially: first check-valves, 17, one ends are connected with off-premises station heat exchanger 12 through pipeline 43; First capillary, 16, one ends are connected with off-premises station heat exchanger 12 through pipeline 43; First interface of condenser 30 is connected with the other end of said first check-valves 17, the other end of first capillary 16 through pipeline 44.
In the utility model specific embodiment, condenser 30 is close to parallel setting with off-premises station heat exchanger 12, is arranged on the inlet side of off-premises station heat exchanger 12.Condenser 30 utilizes the suction wind of outdoor machine fan to make cold-producing medium heat release, condensation.
In the utility model specific embodiment, the pipeline 44,43 of off-premises station heat exchanger 12 is the single hole copper pipe, and in order to improve the radiating efficiency of condenser 30, the material of condenser 30 is an aluminium.
With reference to figure 7; During cooling operation; Cold-producing medium is discharged from compressor 10; Through pipeline 41, cross valve 11, pipeline 42, off-premises station heat exchanger 12, pipeline 43, first check-valves 17, pipeline 44, condenser 30, pipeline 45, second capillary 18, pipeline 46, heat exchanger indoor unit 13, pipeline 47, cross valve 11 and pipeline 48, return compressor 10 again.In the air conditioner refrigerating process, owing to cooling operation causes the off-premises station environment temperature high, and under the situation about can not fully dispel the heat owing to the aluminium fin deterioration of off-premises station heat exchanger 12, cold-producing medium can not fully liquefy in off-premises station heat exchanger 12.When the cold-producing medium that in off-premises station heat exchanger 12, can not liquefy passed through condenser 30, the heat-sinking capability of condenser 30 was very good, can make the cold-producing medium heat release, the liquefaction that do not have liquefaction.The air conditioner refrigerating efficient that so also just can avoid occurring in the prior art is poor, causes sending the temperature of the cold-producing medium that returns compressor high, vicious circle occurs, pressure is risen and causes that high pressure shuts down such problem.
In order to make condenser 30 have good heat radiation, heat absorption capacity; Therefore has many stands condenser pipe in the condenser pipe in the condenser 30; In the utility model embodiment, each sub-condenser pipe area of section the area of section of off-premises station heat exchanger 12 30% in.In addition, the area of section of the cross section total area ratio off-premises station heat exchanger 12 of a plurality of sub-condenser pipes is big more than 5%, eliminates the resistance of flow of refrigerant.To second interface, the temperature of cold-producing medium is cooled off more than 3 ℃ from first interface of condenser 30, and cold-producing medium is able to condensation thus, thereby can carry out the highly effective refrigeration running.Thus, cold-producing medium can liquefy in condenser 30 during owing to cooling operation, so can improve the indoor set heat-exchange capacity.Through making cold-producing medium liquefaction, can reduce running pressure, reduce compressor load, through under low current, turning round, can reduce power consumption.
With reference to figure 8; When heating running; Cold-producing medium is discharged from compressor 10; Through pipeline 48, cross valve 11, pipeline 47, heat exchanger indoor unit 13, pipeline 46, second check-valves 19, pipeline 45 condensers 30, pipeline 44, first capillary 16, pipeline 43, off-premises station heat exchanger 12, pipeline 42, cross valve 11 and pipeline 41, return compressor 10 again.When heating running, ambient temperature is low usually, will frosting on the off-premises station heat exchanger 12.In the present embodiment, for preventing 12 frostings of off-premises station heat exchanger, set up condenser 30; Carry through first check-valves 17 owing to supply to the cold-producing medium of condenser 30 from heat exchanger indoor unit 13, be not depressurized, so; The cold-producing medium process condenser 30 that temperature is higher, the wind that becomes warm through condenser 30 is transported to off-premises station heat exchanger 12, makes the frosting of off-premises station heat exchanger 12 be difficult to produce; Thus, the defrosting running reduces, thereby can carry out the high efficiency running that heats.Certainly, do not heat the switching of running, defrosting running yet, make power consumption descend.
Heat exchanger indoor unit and off-premises station heat exchanger when cooling operation with heat when running, it makes the function of condensation of refrigerant and the function of gasification take place to replace.Therefore, must make the capacity of off-premises station heat exchanger and heat exchanger indoor unit roughly the same.Condenser is assisted the condensation of off-premises station heat exchanger when cooling operation, and when heating running, carries out condensation, the heat radiation of indoor heat converter.That is, realized changing off-premises station and indoor set the heat-exchange capacity balance, carry out the structure of high-efficient operation.
