System for controlling Refrigerating circuit and air-conditioning circuit of saloon car chill box

Abstract

A system for controlling the refrigeration circuit and air-conditioning circuit of a car refrigerator, including a compressor, a condenser, a liquid receiver, a tee, an A solenoid valve, a B solenoid valve, capillary tubes, a refrigerator evaporator, a gas-liquid separator, and thermal expansion Valves, cabin evaporators, controllers, temperature sensors. The device controls the opening and closing of two electromagnetic valves according to the temperature signal collected by the temperature sensor. When the interior temperature of the car meets the requirements and the refrigerator still needs to be refrigerated, the car air conditioner controller turns off the solenoid valve A and opens the solenoid valve B so that the refrigerant only passes through the evaporator of the refrigerator; when the refrigerator does not need refrigeration, the car room needs air conditioning At the same time, the A solenoid valve is opened, and the B solenoid valve is closed at the same time. The refrigerant enters the evaporator of the car compartment through the thermal expansion valve and starts to refrigerate. The agent passes through the refrigerator evaporator and the car compartment evaporator to absorb the heat in the refrigerator and the car compartment respectively until the requirements are met.

Description

Technical field [0001] The present invention relates to a system for controlling the refrigeration circuit and air conditioning circuit of a car refrigerator, in particular to a system for the car refrigerator refrigeration circuit and air conditioning circuit that can realize the independent control of the temperature in the refrigerator and the temperature of the car indoor air conditioning, and belongs to the refrigeration system. And automotive air conditioning technology. technical background [0002] With the improvement of people's living standards, cars have entered the family. People not only have higher and higher requirements for the comfort of cars, but also have more and more requirements for their functions. For example, when people drive out for sightseeing, summer vacation, vacation, or visiting relatives and friends, they often need to carry some items that need refrigeration. The portable refrigerator on the car is not only limited in volume, but also takes up a...
