Automatic constant temperature device of electric controlled area of bus air conditioning compressor

Abstract

The invention discloses an automatic constant temperature device of an electric controlled area of a bus air conditioning compressor comprising a vaporization zone composed of an evaporator and an evaporation fan, a condensation zone composed of a condenser and a condenser fan, and a compression zone composed of a compressor, a four-way valve, a gas-liquid separator and an electronically controlled control zone. The device is characterized in that the electronically controlled control zone comprises an electric cabinet and an automatic constant temperature device, wherein the automatic constant temperature device comprises a suction fan, an exhaust fan and an automatic constant temperature controller; the suction fan and the exhaust fan both comprise ventilating openings, constant temperature blower fans and dust screens; the automatic constant temperature controller is electrically connected with the constant temperature fans; the suction fan is installed between the vaporization zone and the electrically controlled control zone; the exhaust fan is installed between the condensation zone and the electrically controlled control zone. The device of the invention has the advantages that: the automatic constant temperature device improves the adaptability and the stability of the air-conditioning of the bus, so as to realize the effect of positive pressure, dust-free and constant temperature of the electric cabinet.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an automatic constant temperature device for an electronically controlled control area of ​​a passenger car air-conditioning compressor. Background technique [0002] At present, the working environment of the passenger car air conditioner is relatively harsh, and the requirements for the electronic control system of the air conditioner are high. Especially in the hot summer weather, the reliability and stability of the electronic control are extremely important. In high temperature weather, due to the high ambient temperature and the passenger car air conditioner installed on the top of the bus, the internal temperature of the air conditioner rises sharply, and the electric control is prone to high temperature protection, resulting in shutdown and affecting normal use. In addition, due to the influence of the evaporating fans and condensing fans on both sides of the electric...

AI Technical Summary

Problems solved by technology

In high temperature weather, due to the high ambient temperature and the passenger car air conditioner installed on the top of the bus, the internal temperature of the air conditioner rises sharply, and the electric control is prone to high temperature protection, resulting in shutdown and affecting normal use

In addition, the electric control control area of ​​the passenger car air conditioner in the market is affected by the evaporating fans and condensation fans on both sides, so that the electric control control area is in a negative pressure state for a long time, and there are no dust-proof measures, resulting in the electric control box being covered with dust , affect heat dissipation, accelerate corrosion and oxidation, and increase the failure rate of passenger car air conditioners
