CONTROL METHOD FOR INVERTER AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2021/223530
Kind Code:
A1
Abstract:
The present invention relates to a control method for an inverter air conditioner. When an inverter air conditioner enters a stable running state and runs at a first target frequency, under the condition that the outdoor temperature and the indoor temperature remain unchanged, the control method comprises controlling the inverter air conditioner to: run at the first target frequency for a first time period; after the first time period, run at a second target frequency lower than the first target frequency for a second time period, wherein the second time period is shorter than or equal to the first time period; and after the second time period, repeat the step of running at the first target frequency for the first time period. According to the control method, without affecting the cooling or heating effect of an inverter air conditioner, the frequency of the compressor is appropriately reduced to reduce the output power of the compressor, thereby achieving the purpose of energy saving. The control method also well embodies the concept of environmental protection and energy saving.
