Abstract

PURPOSE: To prevent cold draft in a room and finely adjust the temperature of air in the room, by energizing an auxiliary heater while a pole change compressor is temporarily stopped at the time of its pole change in heating.
CONSTITUTION: When the number of poles of the pole change compressor of a heat pump is shifted by a pole change relay 7, the compressor is temporarily stopped by a delayed relay 6 whose energization is controlled by a thermal timer 9. The energization of the auxiliary heater is controlled by the delayed relay 6 and the pole change relay 7. An inside unit is equipped with the auxiliary heater. The auxiliary heater is energized while the compressor is temporarily stopped in heating.
