Defrosting control method of air conditioner and air conditioner

Abstract

The invention belongs to the technical field of air conditioners and provides a defrosting control method of an air conditioner and the air conditioner in order to solve the problem that an existing air conditioner cannot select the optimal defrosting mode by judging conditions. The defrosting control method comprises the following steps that whether the photovoltaic voltage is larger than or equal to a first preset voltage or not is judged; if the photovoltaic voltage is larger than or equal to the first preset voltage, the air conditioner is made to enter in a first defrosting mode; if the photovoltaic voltage is smaller than the first preset voltage, whether the battery voltage is larger than or equal to a second preset voltage or not is judged; if the battery voltage is larger than or equal to the second preset voltage, the air conditioner is made to enter in a second defrosting mode; and if the battery voltage is smaller than the second preset voltage, the air conditioner is made to enter in a third defrosting mode. By judging the conditions of the photovoltaic voltage and the battery voltage, the air conditioner is made to adopt the optimal defrosting mode, thus the defrosting effect of the air conditioner is guaranteed, the heating effect of the air conditioner at the time of defrosting is improved, and accordingly the comfort degree of the indoor environment is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner defrosting control method and the air conditioner. Background technique [0002] As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased by the refrigerant passing through the circulation pipeline through high-pressure / low-pressure / gas / liquid state transitions, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. Under heating conditions, the outer coil of the outdoor unit (evaporator) of the air conditioner is prone to frost, and the frost on the outer coil will lead to a decline in the performance of the refrigeration system, thereby affecting the heating effect of the air conditioner and reducing the indoor temperature. The comfort of the environment affects the user experience. Th...

Problems solved by technology

[0005] In order to solve the above problems in the prior art, that is, in order to solve the problem that the existing air conditioner cannot select the optimal defrosting mode by judging the conditions, the present invention provides a defrosting control method for the air conditioner, which includes the following steps : When the air conditioner is in heating mode, judge whether the photovoltaic voltage is greater than or equal to the first preset voltage; if the photovoltaic voltage is greater than or equal to the first preset voltage, make the air conditioner enter the first defrosting mode; if the photovoltaic voltage If the voltage is less than the first preset voltage, it is further judged whether the battery voltage is greater than or equal to the second preset voltage; if the battery voltage is greater than or equal to the second preset voltage, the air conditioner enters the second defrosting mode; The second preset voltage will make the air conditioner enter the third defrosting mode
