Heating and cooling system used in carriage of electric automobile

Abstract

The invention discloses a heating and cooling system in a carriage of an electric automobile, comprising a water way assembly, a shell with an air passage, and an air blower, wherein the water way assembly comprises a main water tank for heating or cooling and a water circulating tank; the main water tank is communicated with the water circulating tank so as to heat or cool return water of the water circulating tank; the water circulating tank is installed in the shell; and the air blower blows facing to the water circulating tank so as to introduce hot air or cold air into the carriage of the automobile through the air passage. When the heating and cooling system is used, different heating and cooling modes are selected, therefore, the heating and cooling system can respectively independently or comprehensively and simultaneously work without mutual influence, can effectively obtain heating and cooling effects of various modes, needs compressors or any chemical refrigerant and special lubricating oil no more, purifies the air, has simple use mode and long service life, is more beneficial to environment protection and energy saving, is suitable to industrialized production, and is an environment-friendly air conditioner which is not only suitable for use on electric automobiles, but also suitable for use on other aspects.

Description

technical field [0001] The invention relates to the cooling and heating technology of an automobile air conditioner, in particular to a heating and cooling system used in the compartment of an electric vehicle. Background technique [0002] At present, electric car air conditioners at home and abroad use electric drive compressors for air conditioning refrigeration, which are mainly composed of compressors, condensers, throttling devices, evaporators and other devices. After being extracted and compressed, it is sent to the condenser for cooling and condensation, and the heat is released into the air through the heat sink. The refrigerant also changes from gaseous state to liquid state, and the pressure increases. The refrigerant is throttled by the throttling device from the condenser, and then sprayed into the evaporator, the pressure drops suddenly, and the liquid refrigerant immediately turns into a gaseous state, absorbing a large amount of heat in the air through the h...

AI Technical Summary

Problems solved by technology

The wind from the fan turns into hot air after passing through the heating wire, and the hot air flows into the compartment through the channel. The heating wire currently used is prone to deformation in high temperature, and it is not easy to repair after deformation, the service life is short, and the electric energy of the battery needs to be consumed. Reduced driving range, high manufacturing cost, very unsuitable for use on electric vehicles
