AI Technical Summary

Technical Problem

When an air conditioner switches to cooling mode during defrosting, the indoor temperature drops significantly, affecting user comfort.

Method used

By acquiring the air conditioner's operating mode, outdoor temperature, and outdoor heat exchanger coil temperature, the temperature difference is calculated. Based on these values, the target valve is activated to allow refrigerant inside the indoor heat exchanger to flow into the outdoor heat exchanger coil, preventing the system from switching to cooling mode, raising the outdoor unit coil temperature, preventing frost formation, and slowing down the drop in indoor temperature.

Benefits of technology

Maintaining heating mode prevents outdoor unit from frosting and slows down indoor temperature drop, improving user comfort when using the air conditioner.

Abstract

This application discloses an air conditioner control method, comprising: acquiring the air conditioner's operating mode, outdoor temperature value, and coil temperature value of the outdoor heat exchanger; determining the temperature difference between the outdoor temperature value and the coil temperature value when the operating mode is heating mode; and activating a target valve located on a target pipeline based on the outdoor temperature value, coil temperature value, and temperature difference value, so that refrigerant inside the indoor heat exchanger flows into the coil of the outdoor heat exchanger; wherein the target pipeline is used to connect a first port of the indoor heat exchanger and a second port of the coil. This method can raise the temperature of the outdoor unit's coil without switching the air conditioner to cooling mode, thereby slowing down the rate of indoor temperature decrease while defrosting or preventing frost buildup, thus improving user comfort when using the air conditioner.
