HEAT PUMP HEATING APPARATUS

摘要

In a heat pump heating apparatus of this invention, a compressor included in a refrigerating cycle is operated at a speed corresponding to a blowoff temperature so that the temperature of air blown off into a room through an indoor fan from a condenser becomes close to a set value when a room temperature is less than its set value. The indoor fan is operated depending upon a room temperature, i.e., is operated under the state of a relatively great airflow when the room temperature is far lower than its set value and is operated under the state of a relatively small airflow when the room temperature is closer to its set value.
