Abstract

The invention discloses a running and parking integrated air conditioner and a control system thereof. The running and parking integrated air conditioner comprises a running compressor, a parking compressor, an air blower, a controller, a speed regulation module, a condenser, an expansion valve, an evaporator and an indoor temperature sensor. The running compressor is a power take-off compressor, the parking compressor is an electric compressor, the driving compressor and the parking compressor are communicated with the condenser through a one-way valve, the liquid outlet end of the condenser is communicated with the liquid inlet end of the expansion valve, the air outlet end of the expansion valve is communicated with the air inlet end of the evaporator, the running compressor and the parking compressor are communicated with the evaporator through a three-way connector, and the running and parking integrated air conditioner judges the refrigeration mode through the controller. The design not only can automatically judge the air-conditioning mode and realize the effect of economically operating the air conditioner, but also can reduce the space occupation of the air-conditioning system, improve the usable space of the cab and effectively improve the comfort of the driver.

Description

technical field [0001] The invention relates to a vehicle air conditioner, in particular to a walk-station integrated air conditioner and its control system, which is particularly applicable to a walk-station dual-purpose air-conditioning system for improving fuel economy. Background technique [0002] With the gradual improvement of living standards, car drivers have higher and higher requirements for the comfort of the cab, especially in the hot summer, the good cooling performance of car air conditioners plays a vital role in the entire driving process; currently commercial vehicles The parking air conditioning system in the market is divided into two categories, one is to use a fuel generator to drive the compressor, and the other is to use a battery to directly drive a household air conditioner or a top-mounted air conditioner that is independent of the driving air conditioning system. [0003] These two kinds of parking air conditioners can both adjust the temperature ...
