AIR CONDITIONING SYSTEM AND ITS OPERATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an air conditioning system in which heat consumption due to dehumidification operation can be suppressed while sustaining the humidity within a correct range without relying upon a humidity sensor. SOLUTION: The air conditioning system 1 comprises an indoor unit 4 including a heat exchanger 5 for cooling and a heat exchanger 6 for heating, a setter 40 which can designate a dehumidification mode as an operating mode of the indoor unit 4, and a controller 31 controlling the indoor unit 4 to perform dehumidification operation for cooling the air by supplying cold water from a cold heat source 2 to the cooling heat exchanger 5 in response to designation of dehumidification mode from the setter 40 and heating the cooled air by supplying hot water from a hot heat source 3 to the heating heat exchanger 6 wherein dehumidification operation is executed intermittently for a specified limit time at a time while interposing a specified interruption period when dehumidification operation is designated.
