Problems solved by technology

The air conditioning system is in a refrigeration cycle during defrosting operation. The air conditioning system needs to absorb the heat from the indoor side for defrosting. Periodic defrosting or frequent defrosting of the unit will make the unit unable to continue heating, resulting in a large indoor temperature. The longer the defrosting time is, the greater the fluctuation of the indoor temperature will be, which will affect the user's comfort experience

Abstract

The application relates to an air conditioner heating control method, a controller and an air conditioner, and belongs to the air conditioner heating technology field. The air conditioner heating control method includes: acquiring weather parameters, wherein the weather parameters comprise temperature and humidity; confirming if normal heating running is needed or defrosting heating running is needed according to the weather parameters; and performing heating running control according to a confirmed result, wherein under the normal heating running, all coolant output by a compressor flows towards an indoor heat exchanger, and under the defrosting heating running, a part of the coolant flows into the indoor heat exchanger, the other part of the coolant flows towards a part, confirmed to perform defrosting, of heat exchange units in an outdoor heat exchanger, and the other heat exchange units in the outdoor heat exchanger are in a normal work state. The air conditioner heating control method can achieve adaptive continuous heating control by using the weather parameters, facilitates grasp of switching time of the normal heating running and the defrosting heating running well, and then facilitates improvement of heating effect and improvement of comfort experience of users.

Description

technical field [0001] The present application belongs to the technical field of air conditioning and heating, and specifically relates to an air conditioning heating control method, a controller and an air conditioner. Background technique [0002] During the heating operation of the air-conditioning system, the indoor unit heat exchanger acts as a condenser, and the outdoor unit heat exchanger acts as an evaporator. Affected by weather factors, frost may form on the surface of the outdoor heat exchanger. Therefore, the air-conditioning system switches to the cooling operation mode after a period of heating, and relies on the high-temperature and high-pressure refrigerant vapor discharged from the compressor to defrost the outdoor heat exchanger. The air-conditioning system is in a refrigeration cycle during defrosting operation. The air-conditioning system needs to absorb the heat from the indoor side for defrosting. Periodic defrosting or frequent defrosting of the unit ...
