The invention relates to the technical field of parking air conditioners, and in particular relates to a self-cleaning control method of a parking air conditioner. The invention aims at solving a problem that existing parking air conditioners cannot perform self-cleaning. To solve the above problem, the self-cleaning control method of the parking air conditioner of the present invention includes the steps of: detecting an actual pressure P on a high pressure side of the parking air conditioner; based on an outdoor ambient temperature Tao, an operating frequency f of the compressor, an openingdegree B of a throttle valve, and an operating speed r1 of an external fan, determining a theoretical pressure Pc of the high pressure side of the parking air conditioner; comparing the actual pressure P with the theoretical pressure Pc; and based on the comparison result, selectively controlling the parking air conditioner to enter the self-cleaning mode. Through the above control manner, the control method of the present application can enable self-cleaning of the outdoor radiator in a timely and effective manner when an outdoor radiator is dirty, thereby ensuring the heat exchange effect ofthe outdoor radiator, and reducing the power consumption of batteries.
Description
technical field [0001] The invention relates to the technical field of parking air conditioners, in particular to a self-cleaning control method for parking air conditioners. Background technique [0002] With the development of the transportation industry, transport trucks, RVs, buses, etc. are equipped with automotive air conditioners. Traditional automotive air conditioners rely on the automotive engine to drive the mechanical compressor during operation or the automotive engine to generate electricity for the air conditioner compressor to operate. But in the engine-off state of the car, if the driver needs to turn on the air conditioner when resting in the car, he can only restart the car engine to drive the car air conditioner to run in a fuel-consuming manner. Obviously, such an operation method leads to a substantial increase in the transportation cost of the car. [0003] In order to solve the above problems, a parking air conditioner is provided in the prior art. C...
