Technical Field

The invention relates to the technical field of automobile air conditioners, in particular to a refrigeration system for a tank valve of an automobile air conditioner.

Background

The automobile air conditioner is an air conditioning device installed on an automobile, and can cool, heat, ventilate and purify air in a carriage, provide comfortable riding environment for passengers, reduce fatigue strength of drivers, and improve driving safety, and the air conditioning device becomes one of the signs for judging whether the functions of the automobile are complete or not.

Generally comprises a refrigerating device, a heating device and a ventilation device, the combined device makes full use of the limited space in the automobile, has simple structure and convenient operation, and is an internationally popular modern automobile air conditioning system.

The output of the refrigerant of the existing automobile air-conditioning refrigeration system is not easy to control, the refrigeration efficiency is low, and the surface of an evaporator is easy to freeze.

Disclosure of Invention

In order to solve the technical problem, the invention discloses a vehicle air conditioning tank valve refrigeration system, which adopts a valve tank to control the temperature of an evaporator, wherein the valve tank is formed by installing an expansion valve and a pressure valve on the upper part of a liquid storage dryer, and the expansion valve and the pressure valve form a component, so that the pipeline and the space are saved, and the performance is reliable.

In order to achieve the purpose, the invention adopts the following specific technical scheme:

A refrigeration system for a tank valve of an automobile air conditioner comprises an evaporator, an oil overflow pipe, a compressor, a condenser and a tank valve.

In a further development of the invention, the evaporator is connected to the compressor, the compressor is connected to the condenser, the condenser is connected to the tank valve, and the tank valve is connected to the evaporator, forming a cyclic system.

The invention is further improved, and the whole system is connected into a closed loop through an oil spill pipe.

In a further development of the invention, the tank valve comprises an expansion valve, a pressure valve and a storage dryer, the expansion valve and the pressure valve being mounted in the upper part of the storage dryer. High-temperature refrigeration vapor output by the compressor is cooled and liquefied by the condenser, enters the tank valve, is throttled and depressurized, enters the evaporator, is evaporated and absorbs heat to form low-pressure vapor, enters the tank valve to control the evaporation pressure of a refrigerant, then exits from the tank valve and enters the compressor, and a refrigeration cycle is completed. The tank valve controls the evaporating pressure of the refrigerant, so that the refrigerating system can keep the maximum refrigerating capacity under various working conditions, the evaporator is prevented from being frozen, and the refrigerating machine oil released from the bottom of the evaporator flows back to the compressor from the oil overflow pipe through the tank valve.

The invention has the beneficial effects that: compared with the existing automobile air-conditioning refrigeration system, the invention adopts the valve pot to control the temperature of the evaporator, the valve pot is that the expansion valve and the pressure valve are both arranged on the upper part of the liquid storage dryer, and the three form a component, thus saving the pipeline, saving the space and having reliable performance.
