Air conditioning system of electric transport vehicle

Abstract

The invention discloses an air conditioning system of an electric transport vehicle, which comprises a frequency converter, an electric compressor, a liquid storage tank, a reversing valve, an outer condenser, an inner condenser, an inner evaporator, an electronic expansion valve and a waste heat recovery device, the frequency converter is electrically connected with the electric control end of the electric compressor through a lead; the electric compressor is connected with the liquid storage tank, the outer condenser, the inner condenser and the inner evaporator through a conduit to form a loop; the reversing valve is arranged between the heat exchanger and the electric compressor; the electronic expansion valve is arranged between the inner condenser, inner evaporator and the outer condenser. According to the invention, by arranging the waste heat recovery device, the waste heat of the driving motor of the vehicle can be recovered, so that the heat exchange with a refrigerant is carried out, the loss of energy is reduced, and when a group of condensers and an evaporator are arranged in the vehicle, the problem of frost on the windshield, when the cold mode and the hoe mode are switched, is solved.

Description

technical field [0001] The invention belongs to the field of equipment manufacturing, and more specifically relates to an air-conditioning system for an electric transport vehicle. At the same time, the invention also relates to a control method of the air conditioning system of the electric transport vehicle. Background technique [0002] As people's requirements for cars continue to improve, people always hope that they can maintain a relatively comfortable state in the compartment. The function of the car air conditioner is to keep the temperature, humidity, air cleanliness and air fluidity in the car in a comfortable state. Compared with traditional fuel vehicles, electric vehicles use batteries as driving power. Due to the limited capacity of batteries used as driving power, the performance of electric vehicles is seriously affected by the energy saving of the air conditioning system. The traditional electric vehicle air conditioning system is generally composed of co...

AI Technical Summary

Problems solved by technology

The traditional electric vehicle air conditioning system is generally composed of compressors, condensers, evaporators and connecting pipelines. Its high power consumption greatly reduces the battery life of electric vehicles. Therefore, we need an electric vehicle with lower energy consumption. air conditioning system to solve the above problems
