Abstract

PURPOSE:To economically operate an engine driven type room airconditioner by automatically controlling the rotating speed of an engine which drives a coolant compressing compressor of a coolant circuit in response to the cooling/heating load, thereby suitably obtaining the colling/heating capacity responsive to the load. CONSTITUTION:The captioned airconditioner has a compressor 2 driven by an engine 1, a hot water heat exchanger 20 in a hot water tank 18, an outdoor heat exchanger 3 and an indoor heat exchanger 4 in a coolant utilizing cooling/heating circuit. The cooler/heater also has an engine heat utilizing cooling/heating circuit which is composed of a hot water storage heat exchanger 19 for heating water for hot water with coolant of the engine 1 and the hot water in the tank 18, indoor and outdoor heat exchangers 7, 16 aligned in the vicinity of the heat exchangers 4, 3 and a circulation pump 15, etc. In tis case, a speed shifting mechanism 37 between the engine 1 and the compressor 3 is automatically decelerated in accordance with the engine operating state so that with at least cooling/heating load in low state the engine is not displaced from an adequate combustion range.
