Problems solved by technology

Existing air conditioners generally use the running time + outdoor coil temperature to judge whether to enter defrosting, but this method does not directly reflect the actual heating capacity of the air conditioner, and what really affects the user is the heating capacity of the air conditioner

Embodiment Construction

[0017] In order to make the embodiments, technical solutions and advantages of the present invention more obvious, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Example. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0018] Such as figure 1 As shown, the air conditioner defrosting control method of the present invention includes the following steps: S110, starting from the first time the air conditioner enters the defrosting mode after starting up, calculate the cumulative heating capacity Q of the air conditioner in real time 累计 ; S120, compare the cumulative heating capacity Q 累计 With the preset heati...

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner defrosting control method. In order to prevent excessive room temperature fluctuation during defrosting, the defrosting control method comprises the following steps that the accumulated heating capacity Q accumulation of the air conditioner is calculated in real time, and the calculation starts from the time when the air conditioner enters the defrosting mode for the first time after the air conditioner is started; and the accumulated heating capacity Q accumulation is compared withthe preset heating capacity Q, and whether the air conditioner enters the defrosting mode again or not is judged according to the comparison result, wherein the time for entering the defrosting modeof the air conditioner for the first time after the air conditioner is started is determined according to the following modes that the time T for entering the defrosting mode of another air conditioner consistent with the air conditioner in model for the first time after each starting in the same environment and under the same operating condition is acquired, and the time for entering the defrosting mode of the current air conditioner for the first time after the current air conditioner is started is determined according to the time T. According to the air conditioner defrosting control method, the time for entering the defrosting mode of the air conditioner for the first time after the air conditioner is started can be judged more accurately, and the influence on the indoor temperature inthe defrosting process can be reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner defrosting control method. 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. When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and affec...
