Heat pump air conditioner control method and device, electronic equipment, storage medium and vehicle

Abstract

The invention relates to a heat pump air conditioner control method and device, electronic equipment, a storage medium and a vehicle, and relates to the technical field of air conditioners or automobile air conditioners. The control method comprises the steps that a heating control signal is received, and the external environment temperature, the first temperature of a first heat exchanger and thesecond temperature of a second heat exchanger are obtained; determining a heating mode according to the heating control signal, the second temperature and the environment temperature, and determiningwhether the first heat exchanger needs to be defrosted or not according to the heating mode and the first temperature; if defrosting is needed, whether the defrosting starting condition is met or notis determined according to the environment temperature and the second temperature; if the defrosting starting condition is met, the second heat exchanger and the defrosting assembly are controlled todefrost the first heat exchanger, and whether defrosting is completed or not is determined; and if yes, the first heat exchanger and the first heating assembly are controlled to enable the third heatexchanger to conduct heating. Defrosting of the heat exchanger can be realized.

Description

technical field [0001] The present disclosure relates to the technical field of air conditioners or automobile air conditioners, in particular to a heat pump air conditioner control method and device, electronic equipment, storage media, and vehicles, and in particular to an electric vehicle frost-free-new energy heat pump air conditioner system suitable for severe cold regions. Background technique [0002] With the improvement of people's lives, more and more families choose comfortable and fast cars. In recent years, with the rising energy costs, global warming and air pollution and other problems, the energy consumption and pollution problems of traditional cars have become increasingly prominent. Energy-saving and environment-friendly electric vehicles have emerged at the historic moment. After years of development and promotion, electric vehicles have become very popular. In response to extreme weather in severe cold regions, the proportion of energy consumption of ele...
