<p>PURPOSE: To obtain comfortable feeling at the time of cooling even if an indoor unit is installed near a floor surface. CONSTITUTION: An indoor heat exchanger 9 is split to a first heat exchanger 9a of a lower side and a second heat exchanger 9b of an upper side, and a sub-electronic expansion valve 13 is provided between the exchangers 9a and 9b. At the time of cooling, refrigerant is passed from the exchanger 9a toward the exchanger 9b via the valve 13 to raise the evaporating temperature of the exchanger 9a to higher than the evaporating temperature of the exchanger 9b, and the temperature of the air diffused from a first air outlet 17 of the lower side through the exchanger 9a is raised higher than that of the air diffused from a second air outlet 19 of the upper side through the exchanger 9b, thereby preventing the excessively cooling at the foot at the time of cooling.</p> |
