Embodiment

[0015] Example: such as figure 1 As shown, a refrigeration system with a tank valve 5 for an automobile air conditioner includes an evaporator 1 , an oil spill pipe 2 , a compressor 3 , a condenser 4 and a tank valve 5 .

[0016] In this embodiment, the evaporator 1 is connected to the compressor 3, the compressor 3 is connected to the condenser 4, the condenser 4 is connected to the tank valve 5, and the tank valve 5 is connected to the evaporator 1 to form a cycle system.

[0017] In this embodiment, the whole system is connected into a closed loop through the oil spill pipe 2 .

[0018] In this embodiment, the tank valve 5 includes an expansion valve, a pressure valve and a storage drier, and the expansion valve and the pressure valve are installed on the upper part of the storage drier. The high-temperature refrigeration vapor output by the compressor 3 is cooled and liquefied by the condenser 4, then enters the tank valve 5, throttles down and then enters the evaporator ...

Abstract

The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioning tank valve refrigerating system. The automobile air conditioning tank valverefrigerating system comprises an evaporator, an oil overflow pipe, a compressor, a condenser and a tank valve. The temperature of the evaporator is controlled through a valve tank. The valve tank ischaracterized in that an expansion valve and a pressure valve are mounted on the upper portion of a storage liquid dryer, and one part is formed by the expansion valve, the pressure valve and the storage liquid dryer, so that pipelines and the space are saved, and the performance is reliable. The piston stroke of the compressor can be changed according to the ratio of high pressure and low pressure to directly influence the compression ratio of the compressor and further to adjust the output amount of a refrigerant, and the refrigerating efficiency is changed. Under the normal working condition, the compressor is continuously operated, a compressor clutch does not perform clutch operation, and it is ensured that the surface of the evaporator is not frozen.

Description

technical field [0001] The invention relates to the technical field of automobile air conditioners, in particular to an automobile air conditioner tank valve refrigeration system. Background technique [0002] Automobile air conditioner refers to the air-conditioning device installed on the automobile, which can cool, heat, ventilate and purify the air in the compartment, provide a comfortable riding environment for the passengers, reduce the fatigue intensity of the driver, and improve driving safety , The air conditioning unit has become one of the signs to measure whether the car is fully functional. [0003] It generally includes refrigeration device, heating device and ventilation device. This combination device makes full use of the limited space inside the car. It has a simple structure and is easy to operate. It is a modern car air-conditioning system popular in the world. [0004] The output of the refrigerant in the existing automobile air-conditioning refrigerati...
