Embodiment 1

[0053] figure 1 It is a schematic diagram of the steps of the air source heat pump control method provided by the embodiment of the present invention. The air source heat pump control method provided by this embodiment may specifically include the following steps:

[0054] S101. When it is determined that the air source heat pump in the heating working state needs to perform a defrosting operation, determine the heating parameters of the air source heat pump.

[0055] Specifically, when the heating mode of the air source heat pump is turned on, the outdoor unit absorbs heat and the indoor unit dissipates heat. When the general heating mode is started, the outdoor temperature is below 10°C. When the outdoor temperature is low, the outdoor unit still needs to absorb heat. , the temperature of the evaporator body will drop below 0°C, and the surrounding moisture will quickly condense into frost. Before defrosting, it is necessary to determine the heating parameters of the air sou...

Abstract

The invention relates to an air source heat pump control method and device and an air source heat pump. The air source heat pump control method comprises the steps that when it is determined that the air source heat pump in a heating working state needs to be subjected to defrosting operation, heating parameters of the air source heat pump are determined; and the air source heat pump is controlled to conduct heating according to the heating parameters, and after heating is completed, the air source heat pump is controlled to conduct defrosting operation. According to the air source heat pump control method and device and the air source heat pump, the influence of defrosting of the air source heat pump on the indoor temperature can be reduced, and the comfort degree of a human body is improved.

Description

technical field [0001] The invention belongs to the field of air source heat pumps, and in particular relates to an air source heat pump control method and device, and an air source heat pump. Background technique [0002] During the use of the air source heat pump, when the heating mode is turned on, the outdoor unit absorbs heat and the indoor unit dissipates heat. Generally, when the heating mode is started, the outdoor temperature is below 10°C. When the outdoor temperature is low, the outdoor unit still needs to absorb heat. When the heat is high, the temperature of the evaporator body will drop below 0°C, and the surrounding moisture will quickly condense into frost. If the air source heat pump is frosted, if the defrosting is not timely, it is easy to block the passage between the fins and increase the air flow resistance. 1. Increase the thermal resistance of the heat exchanger, decrease the heat exchange capacity, decrease the evaporation temperature, decrease the e...
