Abstract

The invention discloses a heat pump type air conditioner, and a defrosting control method and a defrosting control device of the heat pump type air conditioner. The defrosting control method of the heat pump type air conditioner comprises the following steps that the detection temperature of an indoor environment temperature wrap is obtained; the coil temperature of an indoor heat exchanger is obtained; an equivalent temperature difference is obtained according to the temperature difference between the detection temperature of the indoor environment temperature wrap and the coil temperature of the indoor heat exchanger and an equivalent temperature difference coefficient, and integral calculation is made on time by using the equivalent temperature difference, so as to obtain the average heat output of the whole process; and the heat pump type air conditioner is subject to defrosting control according to the average heat output of the whole process. Through using the defrosting control method, the stability and the timeliness of defrosting judgment can be guaranteed.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a heat pump air conditioner and its defrosting control method and device. Background technique [0002] In order to save costs and simplify the controller design and electrical connection, most heat pump air conditioners currently use the comprehensive judgment of the indoor unit ambient temperature sensor and the indoor unit heat exchanger coil temperature temperature sensor for defrosting. [0003] For the above-mentioned fixed-frequency heat pump air conditioner, since the defrosting control logic has a strong dependence on the operating parameters of the air conditioner, specific parameters need to be set to determine whether the unit is frosted. Therefore, after the system configuration changes, the defrosting effect will also occur. Changes may lead to unclean defrosting or frequent defrosting due to untimely defrosting. The self-adaptive ability is not good, and it is easy ...
