Control method and system of air source heat pump and air source heat pump

Abstract

The invention provides a control method and system of an air source heat pump and the air source heat pump. The air source heat pump comprises an outdoor unit. The outdoor unit comprises a compressor, a fan and a heat exchanger. The control method of the air source heat pump includes the steps that when a starting and/or stopping instruction of the compressor are/is received, the running power and/or running current of the fan are/is obtained; whether the running power and/or running current meet/meets a preset condition or not is judged; and when the running power and/or the running current meet/meets the preset condition, a reminding signal for reminding a user to clean the heat exchanger is sent. By means of the control method and system of the air source heat pump and the air source heat pump, the user and after-sales service staff of manufacturers are reminded in time to clean the fin heat exchanger of the outdoor unit and check to solve the problem of too high load of the fan of the outdoor unit, the good heat exchanging effect of the heat exchanger of the outdoor unit is guaranteed, the situation that the electric appliance line is too hot due to too high load of a motor, then the motor is damaged, and consequently economic loss is caused is avoided, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of air source heat pumps, in particular, to a control method for an air source heat pump, a control system for an air source heat pump, and an air source heat pump. Background technique [0002] For the air-cooled heat pump water heater unit (especially the air source heat pump unit in the northern coal-to-electricity transformation), due to the irregular environment around the outdoor unit, the cooling effect around the fin heat exchanger is not good, resulting in high temperature and heat of the motor. If the heat exchanger of the outdoor unit has not been cleaned for a long time, too much dust will accumulate on the surface of the fin heat exchanger, which will cause the air volume of the outdoor unit to be too small, and will also cause the motor load of the outdoor unit to be too large. Especially in the north, due to the serious smog pollution, after each defrosting of the outdoor unit in winter, under...

[0002] For the air-cooled heat pump water heater unit (especially the air source heat pump unit in the northern coal-to-electricity transformation), due to the irregular environment around the outdoor unit, the cooling effect around the fin heat exchanger is not good, resulting in high temperature and heat of the motor. The heat exchanger of the outdoor unit has not been cleaned for a long time, resulting in excessive dust accumulation on the surface of the finned heat exchanger, resulting in too small air volume of the outdoor unit, and excessive load on the motor of the outdoor unit
