A second object of the present invention is to provide an air conditioner, which solves the problem of high cost of the conventional air conditioner.
The third purpose of the invention is to provide an automobile, which solves the problems of poor performance and high cost of the traditional automobile air conditioner.
Embodiments of the present invention are implemented as follows:
a heat pump system, comprising:
the device comprises a compressor, a condenser, an outdoor heat exchanger, a gas-liquid separator, an evaporator, a first electromagnetic stop valve, a second electromagnetic stop valve, a first throttling device and a second throttling device;
the compressor outlet of the compressor is connected with the condenser inlet of the condenser through a first high-pressure pipeline;

the first electromagnetic stop valve is arranged on a second high-pressure pipeline connected with the inlet of the outdoor heat exchanger, and the first throttling device is arranged on a third high-pressure pipeline connected with the inlet of the outdoor heat exchanger;
the outlet of the outdoor heat exchanger is connected with the evaporator inlet of the evaporator through a fourth high-pressure pipeline, and the gas inlet of the gas-liquid separator is connected with the evaporator outlet of the evaporator through a first low-pressure pipeline;
the second throttling device is arranged on a fourth high-pressure pipeline connected with the inlet of the evaporator, and the second electromagnetic stop valve is arranged between the fourth high-pressure pipeline and the first low-pressure pipeline, so that after a first branch of the fourth high-pressure pipeline reaches the second electromagnetic stop valve, the second electromagnetic stop valve is connected with the first low-pressure pipeline, and after a second branch of the fourth high-pressure pipeline reaches the second throttling device, the second throttling device is connected with the inlet of the evaporator;
the compressor inlet of the compressor is connected with the gas outlet of the gas-liquid separator through a second low-pressure pipeline.
The inventor finds that the existing automobile heat pump system generally changes the existing HVAC (heating ventilation and air conditioning) water heating warm air core into a condenser, and the system is simple in structure and control, does not make special design for the heating capacity of the heat pump system, has poorer working temperature range and heat pump heating capacity than other heat pump systems (such as an air supplementing enthalpy increasing heat pump system), and is difficult to meet the heating requirement of the whole automobile. The air-supplementing enthalpy-increasing heat pump system adopts a 2-level throttling and gas-liquid separator and a special air-supplementing enthalpy-increasing compressor on the basis of the heat pump system, has complex structure, too many parts and control, and needs to adopt the special air-supplementing enthalpy-increasing compressor as a core part in the system, and the technology is mastered in the hands of few manufacturers internationally, so that the system has better performance in all aspects and very high cost.
The inventor designs the heat pump system, when the first electromagnetic stop valve and the second throttling device are closed, and the second electromagnetic stop valve and the first throttling device are opened, the high-temperature gaseous refrigerant is discharged by the compressor and passes through the condenser, the condenser cools the high-temperature refrigerant into a liquid state, a large amount of heat is generated and is emitted into the vehicle, the liquid refrigerant flows to the gas-liquid separator again, the gas-liquid separator realizes the enthalpy increasing function of the system, then flows to the first throttling device for throttling, and flows to the gas-liquid separator through the second electromagnetic stop valve after being evaporated by the outdoor heat exchanger, the gas-liquid separator realizes the enthalpy increasing of the system and ensures that the refrigerant flows out and is gaseous refrigerant, and finally the refrigerant returns to the compressor, thereby realizing the circulation of the heat pump heating mode. When the second electromagnetic stop valve is closed, the first electromagnetic stop valve, the first throttling device and the second throttling device are opened, the high-temperature gaseous refrigerant is discharged by the compressor, passes through the condenser, the condenser cools the high-temperature refrigerant into a liquid state, and simultaneously generates a large amount of heat to be emitted into the vehicle, the liquid state refrigerant flows out of the condenser and then is divided into two paths, wherein the first path flows to the gas-liquid separator, the gas-liquid separator realizes the enthalpy increasing function of the system, and then flows to the first throttling device; the second path flows to the first electromagnetic stop valve, then the second path and the refrigerant of the first path pass through the outdoor heat exchanger together, the refrigerant evaporated by the outdoor heat exchanger flows to the second throttling device for throttling, the pressure and the temperature of the throttled refrigerant are reduced, the throttled refrigerant enters the evaporator for evaporation into a gaseous state in a mist (tiny raindrop) form, the evaporation process absorbs heat for cooling, the dehumidification function is realized, then low-temperature low-pressure refrigerant vapor flows to the gas-liquid separator, the gas-liquid separator realizes the enthalpy increase of the system and ensures that the refrigerant flows out and is gaseous refrigerant, and finally the refrigerant returns to the compressor, so that the heating and dehumidification mode circulation is realized. The whole heat pump system does not need a special air supplementing enthalpy increasing compressor, high-temperature high-pressure refrigerant entering from a liquid inlet of the gas-liquid separator and low-temperature low-pressure refrigerant entering from a liquid inlet of the gas-liquid separator are subjected to heat exchange in the gas-liquid separator, so that the low-temperature low-pressure refrigerant enters the compressor after the temperature is increased, the air suction superheat degree of the compressor is increased, the supercooling degree of the refrigerant flowing out from a liquid outlet of the gas-liquid separator and entering the first throttling device is increased, the heat recovery function of the gas-liquid separator is realized, only one gas-liquid separator with the heat recovery function and two throttling devices are used, the cost is greatly reduced, and meanwhile, the use requirement of an automobile can be met.
