Pure electric roof-top air conditioner

Abstract

The invention discloses a pure electric roof-top air conditioner. According to the technical scheme, the pure electric roof-top air conditioner mainly comprises a condenser cavity, a compressor electric appliance cavity and an evaporator cavity, wherein the condenser cavity comprises a condenser shell, a parallel flow condenser and condensate fans; the compressor electric appliance cavity comprises an air flow separator, a secondary shock absorption mechanism, an electric scroll compressor, a pre-charger-discharger and a DC-DC converter; the evaporator cavity comprises evaporation blowers, a dry filter with a visual liquid lens, a thermal expansion valve and four parallel flow evaporators; the thermal expansion value located in the evaporator cavity is connected with the parallel flow evaporators through pipes to control the parallel flow evaporators, and the parallel flow evaporators are made of aluminum alloy and are in a V shape. The pure electric roof-top air conditioner has the advantages of improving the working efficiency, reducing the weight, saving space, improving the heat dissipating and transferring efficiency and increasing the energy efficiency ratio of an air conditioning unit.

Description

technical field [0001] The invention relates to an air conditioner, more specifically, it relates to a pure electric ceiling air conditioner. Background technique [0002] The refrigeration system of electric vehicle air conditioners is basically the same as that of traditional vehicles. It is mainly composed of five major components, including an integrated compressor, condenser, expansion valve, evaporator, and liquid storage dryer. Due to the limited energy of the power battery of the electric vehicle, in order to ensure sufficient mileage of the electric vehicle, the air conditioning system used in the electric vehicle must have a high energy efficiency ratio, and the energy consumption of the air conditioning system should be reduced as much as possible under the premise of meeting the performance of the vehicle air conditioning system. The existing electric vehicle air-conditioning system still has shortcomings in the layout of the vehicle. Some air-conditioning units ...

AI Technical Summary

Problems solved by technology

The existing electric vehicle air-conditioning system still has shortcomings in the layout of the whole vehicle. Some air-conditioning units have the condenser and the evaporator installation chamber close to each other, which seriously affects the heat dissipation and heat transfer efficiency of the two important components; the evaporation of some air-conditioning units The ventilation layout of the device core is unreasonable, which affects the heat dissipation efficiency
