Air conditioning apparatus

Abstract

When the outside air temperature is low, an air conditioner 1 performs a heating operation while a heating unit 2 performs a main heating operation. When the outside air temperature is high, the air conditioner 1 performs a main heating operation, and the heating unit 2 performs an auxiliary heating operation. While the air conditioner 1 performs a heating operation, the heating unit 2 is turned off before the room temperature reaches a set temperature. That is, the heating unit 2 is turned on for a longer time as the outside air temperature becomes lower. In this way, the heating unit 2 is operated under the situation to thereby supplement the heating capacity of the air conditioner 1 , so that comfortable heating is performed.
