Problems solved by technology

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

Abstract

The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner defrosting control method. In order to prevent the room temperature from fluctuating too much during defrosting, the defrosting control method of the present invention includes the following steps: starting from the first time the air conditioner enters the defrosting mode after starting up, calculate the cumulative power consumption W of the air conditioner in real time 累计 and cumulative heating capacity Q 累计 ; compare Q 累计 / W 累计 The value of the value and the preset energy efficiency ratio C, and judge whether to make the air conditioner enter the defrosting mode again according to the comparison result. The present invention uses the preset energy efficiency ratio C as a benchmark to more accurately judge the timing of the air conditioner entering the defrosting mode, thereby avoiding frequent defrosting. And according to the value of Q accumulation / W accumulation, the impact on the indoor temperature during the defrosting process can be reduced to the greatest extent, so that the indoor temperature will not fluctuate greatly.

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...
