AI Technical Summary
Existing heat pump air conditioners experience frost formation during winter operation, leading to a decrease in energy efficiency ratio and heating capacity. Frequent defrosting also affects heating comfort, especially in low-temperature and high-humidity climates.
By triggering a rapid defrosting mode in the air conditioner's heating mode based on the ambient temperature, outdoor unit copper pipe temperature, indoor ambient temperature, and operating time, defrosting is performed using electric auxiliary heating and fan speed adjustment to reduce heat demand.
In the early stages of frost formation, a thin frost quick-melt working mode is adopted to reduce the heat demand for defrosting, improve the comfort of the heat pump air conditioner's heating operation, and avoid large fluctuations in indoor temperature.
