Abstract

The invention relates to the technical field of parking air conditioners, and in particular relates to a control method of a parking air conditioner. The invention aims to solve the problem that existing parking air conditioners have an unreasonable operation mode. To solve the above problem, the control method of the parking air conditioner of the present invention comprises the steps of detecting an output voltage U of a storage battery and an outdoor ambient temperature Tao; calculating the difference between the outdoor ambient temperature Tao and a set temperature T; comparing the outputvoltage U with a rated operating voltage Un of a compressor; based on the comparison result, determining an operating frequency f of the compressor and an operating speed r of an internal fan; and controlling the compressor and the internal fan to operate according to the operating frequency f and the operating speed r, respectively. Through the above control method, the control method of the parking air conditioner of the present application can reasonably control the operation mode of the parking air conditioner based on the outdoor ambient temperature and the voltage of the storage, and control the transportation cost of vehicles.

Description

technical field [0001] The invention relates to the technical field of parking air conditioners, in particular to a control method for parking air conditioners. Background technique [0002] With the development of the transportation industry, parking air conditioners are installed in transport trucks, RVs, and buses. Compared with traditional automotive air conditioners, parking air conditioners do not need to be started by the vehicle engine, but are directly driven by the vehicle battery. It is a more energy-saving and environment-friendly air conditioner when the car is turned off. [0003] However, the charge and discharge times of the battery are limited, and additional fuel is required to charge the battery while driving. Frequent use of the parking air conditioner 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 ...
