Abstract
A control system for use in an air conditioner including a room heat-exchanger and an outside heat-exchanger. For controlling the room temperature, the control system sets a plurality of cooling start temperatures and a plurality of heating start temperatures and compares the room temperature, sensed by a temperature sensor, with the plurality of cooling start temperature and the plurality of heating start temperatures so as to control the outside heat-exchanger in accordance with the comparison results. The plurality of cooling or heating start temperatures includes a first cooling or heating start temperature and a second cooling or heating start temperature lower or higher than the first cooling start temperature. The control system first performs the temperature control on the basis of the first cooling or heating start temperature and then controls it on the basis of the second cooling or heating start temperature under predetermined conditions.
