AIR CONDITIONER AND CONTROL METHOD THEREFOR

WIPO Patent Application WO/2022/017546

A1

An air conditioner and a control method therefor. A first coil temperature sensor and a second coil temperature sensor are arranged on an indoor heat exchanger, the first coil temperature sensor being located at a minimum temperature position of the indoor heat exchanger when the exchanger is acting as an evaporator, and the second coil temperature sensor being located at a maximum temperature position of the indoor heat exchanger when the exchanger is acting as an evaporator. When the air conditioner is in a cooling state, a first coil temperature serves as a control parameter for the air conditioner, thus being able to ensure that the minimum temperature of the indoor heat exchanger is within a set range and not too low so to cause freezing and leakage of water. When the air conditioner is in a heating state, a second coil temperature serves as a control parameter for the air conditioner, thus being able to ensure that the maximum temperature of the indoor heat exchanger is within a set range so as to not cause a system overload.
