Embodiment Construction

[0014] The embodiment of the present application provides an air conditioner defrosting control method and the air conditioner, and judges the frosting and defrosting on the outdoor heat exchanger according to the indoor coil temperature and the indoor coil temperature drop rate at the end of the air conditioner in this cycle. Frost situation, automatically adjust the heating operation time and defrosting time of the air conditioner in the next cycle, realize the dynamic adjustment of heating time and defrosting time, and solve the defrosting process existing in the defrosting process based on the indoor coil temperature control in the prior art Technical problems with unclean or false defrosting.

[0015] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0016] Such as figure 1 As shown, it is a flow chart of the air co...

Abstract

The invention provides an air conditioner defrosting control method and an air conditioner. The method comprises the following step: after the current defrosting operation period of the air conditioner finishes, calculating and determining the heating operation time and defrosting time of the air conditioner of the next period on the basis of the indoor coil pipe temperature drop rate: when the indoor coil pipe temperature drop rate is high, controlling the heating operation time of the air conditioner of the next period to be less than or equal to the heating operation time of the air conditioner of the current period, and controlling the defrosting time of the next period to be greater than the defrosting time of the current period; and when the indoor coil pipe temperature drop rate is low, controlling the heating operation time of the air conditioner of the next period to be greater than the heating operation time of the air conditioner of the current period, and controlling the defrosting time of the next period to be less than or equal to the defrosting time of the current period. The heating operation time and defrosting time of the air conditioner of the next period are adjusted on the basis of the indoor coil pipe temperature drop rate when the operation of the current period finishes, thereby implementing dynamic adjustment on the heating and defrosting, and solving the technical problem of unclean defrosting or false defrosting when the defrosting is controlled on the basis of the indoor coil pipe temperature.

Description

technical field [0001] The invention relates to the technical field of air conditioners, to an air conditioner defrosting control method and an air conditioner, and in particular to the field of fixed frequency air conditioners. Background technique [0002] During the heating operation of the fixed-frequency air conditioner, the refrigerant exchanges heat with the outdoor air through the outdoor heat exchanger, absorbs heat from the outdoor air and evaporates, and the compressor compresses the low-temperature and low-pressure refrigerant into high-temperature and high-pressure refrigerant vapor, which enters the room. The heat exchanger releases heat and heats the indoor air through the indoor heat exchanger. However, since the outdoor heat exchanger absorbs heat from the outdoor air, the temperature around the outdoor heat exchanger is low, and the water vapor in the air will condense into frost. Adhering to the surface of the outdoor heat exchanger affects the heat exchan...
