Technical field
The utility model is a kind of air conditioner heat pump system, belongs to the improvement technology of air conditioner heat pump system.
Background technology
In the prior art air conditioner heat pump system running, when indoor temperature reaches the air-conditioning design temperature, compressor is out of service, be in holding state, in order to guarantee the high and low pressure side pressure balancing of compressor, to reduce the moment of next compressor start, during this period, the refrigerant in the air-conditioning system will flow to low-pressure side from the high-pressure side under the height action of pressure generally more than 3 minutes compressor stand-by period out of service, thereby the pressure in the air-conditioning system reaches balance, make to start smoothly when compressor is started shooting once more, yet air-conditioning system is set up in the process of pressure reduction in startup, its efficiency is lower, has reduced the efficiency in the air-conditioning heat pump running.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of clean boot that guarantees compressor, the overall operation efficiency that improves air-conditioning system, energy-conservation air conditioner heat pump system is provided.
The technical solution of the utility model is: a kind of air conditioner heat pump system, comprise compressor, outdoor heat exchanger, throttle capillary tube, indoor heat exchanger, gas-liquid separator and cross valve, wherein the exhaust outlet of compressor is communicated with first interface of cross valve, second interface of cross valve is communicated with an end of outdoor heat exchanger, the other end of outdoor heat exchanger is communicated with throttle capillary tube, the other end of throttle capillary tube is communicated with indoor heat exchanger, indoor heat exchanger is communicated with the 4th interface of cross valve, the 3rd interface of cross valve is communicated with the return-air mouth of compressor by gas-liquid separator, it is characterized in that being equiped with magnetic valve on the pipeline between described outdoor heat exchanger and the throttle capillary tube, be equiped with high-pressure check valve on the gas exhaust piping between first interface of the exhaust outlet of compressor and cross valve, be equiped with low pressure check valves on the pipeline between the return-air mouth of gas-liquid separator and compressor.
Above-mentioned high-pressure check valve and low pressure check valves are check valve.
Above-mentioned magnetic valve is substituted by electric expansion valve.
The utility model is owing to adopt the structure that is equiped with magnetic valve, high-pressure check valve and low pressure check valves in system, therefore, it not only can guarantee the safety of compressor, start smoothly, also can make compressor after starting next time, the high and low pressure reduction of system is shorter than the time that pressure reduction is set up in common constant speed air-conditioning system start greatly Time Created, has improved the overall operation efficiency of air-conditioning system, reaches energy-conservation effect.
Description of drawings
Fig. 1 is the utility model air conditioner heat pump system figure;
The specific embodiment
Embodiment 1:
As shown in Figure 1, the utility model air conditioner heat pump system, comprise compressor 1, outdoor heat exchanger 2, throttle capillary tube 3, indoor heat exchanger 4, gas-liquid separator 5 and cross valve 6, wherein the exhaust outlet of compressor 1 is communicated with the first interface a of cross valve 6, the second interface b of cross valve 6 is communicated with an end of outdoor heat exchanger 2, the other end of outdoor heat exchanger 2 is communicated with throttle capillary tube 3, the other end of throttle capillary tube 3 is communicated with indoor heat exchanger 4, indoor heat exchanger 4 is communicated with the 4th interface d of cross valve 6, the 3rd interface c of cross valve 6 is communicated with the return-air mouth of compressor 1 by gas-liquid separator 5, be equiped with magnetic valve 7 on the pipeline between described outdoor heat exchanger 2 and the throttle capillary tube 3, be equiped with high-pressure check valve 8 on the gas exhaust piping between the first interface a of the exhaust outlet of compressor 1 and cross valve 6, be equiped with low pressure check valves 9 on the pipeline between the return-air mouth of gas-liquid separator 5 and compressor 1.
In the present embodiment, above-mentioned high-pressure check valve 8 and low pressure check valves 9 are check valve.
During the utility model compressor shutdown, closed electromagnetic valve blocks the high pressure refrigerant and flows to low-pressure side by throttling arrangement, maintenance system height pressure reduction; High-pressure check valve stops the high pressure refrigerant to flow to compressor from the high-pressure side; high pressure refrigerant between this check-valves and the exhaust outlet of compressor can be revealed to the return-air oral-lateral of compressor by the slit of compressor inside; low pressure check valves stops the inner coolant backflow of compressor to return the system low-voltage side; the pressure of compressor row, return-air mouth reaches balance in will be behind system-down very short time; as mentioned above; in the stopping process of air-conditioning system after start for the first time; intrasystem height pressure reduction is kept always, and the pressure of press row, return-air mouth balance rapidly in stopping process.Therefore, the utility model not only can guarantee the safety of compressor, start smoothly, also can make compressor after starting next time, the high and low pressure reduction of system is shorter than the time that pressure reduction is set up in common constant speed air-conditioning system start Time Created greatly, improve the overall operation efficiency of air-conditioning system, reached energy-conservation effect.
