Problems solved by technology

[0003] The traditional four-way reversing valve reverse defrosting technology has problems such as high energy consumption, low efficiency, and poor user experience. Defrost is carried out on the premise of ensuring the comfort of consumers under frosting conditions, which is based on the It is proposed under the premise that the defrosting does not stop in the heating condition and the indoor unit is running normally. The traditional reverse defrosting technology can no longer meet the needs of modern people.

Abstract

The invention provides a method and device for controlling ultrasonic defrosting, a storable medium and an air conditioner. Based on features like a high frequency, a short wave length and effective energy centralization of ultrasonic waves and the proper control method, defrosting is realized by the ultrasonic waves; effects of frost restraining and defrosting are reached; comfort demands of users in defrosting are satisfied; and efficient frost-free running of a heat pump air-conditioning unit can be expected. The control method comprises the steps that the air conditioner is started for heating, an outdoor environment temperature T<outer ring>, an outdoor heat exchanger coil temperature T<outer coil> and an outdoor environmental relative air humidity h are detected after normal runningfor first preset time t1; when the T<outer ring>, the T<outer coil> and h satisfy preset defrosting working conditions, the air conditioner starts an ultrasonic defrosting mode; and when the preset defrosting working conditions are not satisfied, the air conditioner can keep running under an original working mode, and the pre-set defrosting working conditions are judged for a time at an interval of second preset time t2.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method and device for ultrasonic defrosting, a storable medium and an air conditioner. Background technique [0002] For heat pump air conditioners operating in humid and cold areas, frosting often occurs on the condenser. The existence of frost increases the heat transfer resistance and air flow resistance of the evaporator, which reduces the performance coefficient of the unit and increases the energy consumption during operation. In order to ensure the continuous and efficient operation of the heat pump air conditioner, periodic defrosting is required. [0003] The traditional four-way reversing valve reverse defrosting technology has problems such as high energy consumption, low efficiency, and poor user experience. Defrost is carried out on the premise of ensuring the comfort of consumers under frosting conditions, which is based on the It is prop...
