Method for controlling defrosting of air conditioners by regions and air conditioning unit

Abstract

The invention discloses a method for controlling defrosting of air conditioners by regions and an air conditioning unit using the method. The method comprises the following steps of: storing defrosting operation control modes related to regional climate parameters on an air conditioning unit motherboard; Acquiring the historical climate parameters of the installation area of the air-conditioning unit through the wireless communication module; The historical climate parameters obtained are compared with the climate parameters stored in the motherboard and the defrosting model adapted to the region is selected. The invention can select the optimum frost operation mode adapted to the climate characteristics of the region according to the characteristics of the historical climate parameters ofthe specific region in which the air conditioning unit is installed, so that the actual operation of the unit is combined with the meteorological conditions of the region, the accuracy of defrostingoperation of the heat pump unit is improved, and the high efficiency of heating operation of the unit is ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method for controlling the defrosting of an air conditioner in different regions and an air conditioning unit using the method. Background technique [0002] my country has a vast territory, and the climatic conditions in different regions are quite different, especially in winter, due to the cold wave activity, the meteorological conditions between the north and the south are very different, and the actual operation of the air-conditioning heat pump system in different regions is also very different. In southern China where the temperature is above 7°C, the heating period in winter is short, the heat demand is small, the unit generally does not frost during operation, and the heating performance coefficient is high; while in the central and northern regions, the winter temperature is low, the air humidity is high, and the air conditioner heat pump runs Frost is easy to ...
