Control method of parking air conditioner

Abstract

The invention relates to the technical field of parking air conditioners, in particular to a control method for parking air conditioners. The invention aims to solve the problem of unreasonable operation mode of the existing parking air conditioner. For this purpose, the control method of the parking air conditioner of the present invention includes: detecting the output voltage U of the storage battery and the outdoor ambient temperature T ao ; compare the outdoor ambient temperature T ao The size of the preset temperature T; compare the output voltage U with the rated operating voltage U of the compressor n Based on the comparison result, determine the operating frequency f of the compressor and the operating speed r of the internal fan; control the compressor and the internal fan to operate at the operating frequency f and operating speed r respectively. Through the above control method, the parking air conditioner control method of the present application can reasonably adjust the operation mode of the parking air conditioner based on the outdoor ambient temperature and the battery voltage, and control the transportation cost of the vehicle.

Description

Technical field[0001]The invention relates to the technical field of parking air conditioners, in particular to a control method of parking air conditioners.Background technique[0002]With the development of the transportation industry, parking air conditioners are installed in transport trucks, RVs, buses, etc. Compared with traditional car air conditioners, parking air conditioners do not need to be started by the vehicle engine, but are directly driven by the on-board battery. The car runs in an off state, which is a more energy-saving and environmentally friendly air conditioner.[0003]However, the number of charging and discharging of the battery is limited, and additional fuel needs to be consumed to charge the battery when driving. Frequent use of parking air conditioners will not only affect the service life of the battery, but also increase the transportation cost due to fuel consumption. Therefore, how to control the parking air conditioner to operate more reasonably is very...
