とがある。(B) Conventional technology As an air conditioner for cooling and heating a plurality of rooms at the same time, for example, as shown in JP-B-51-11427, air for exchanging heat with a use-side heat exchanger installed in each room with room air is disclosed. A direct expansion method as a heat exchanger, and as shown in, for example, Japanese Utility Model Publication No. 52-47877, the use side heat exchanger is a water heat exchanger,
There is a chiller system in which cold and hot water cooled or heated by the water heat exchanger is circulated through a fan coil unit in each room to cool and heat.
