Abstract

PURPOSE: To reduce a room cooling or a room heating load of an air-conditioner by a method wherein a return duct drawing cool air in an cold area is provided with a switching device for discharging the air to outside of a shop in an air-conditioning system in a supermarket which is displaying an open showcase therein.
CONSTITUTION: Cool air in an cold area 5 is sucked into a return duct 18 and is introduced into an air-conditioning machine 21 through a duct switching device 23 switched to a position A upon room cooling or dehumidifying and the air-conditioning machine 21 is operated for the room cooling or the dehumidifying to cool or dehumidify the air which is blown off into a shop through a supply duct 40. In intermediate seasons such as spring, autumn or the like, the air-conditioning machine 21 is not operated and the air is recirculated directly into the shop. In a room heating operation, the switching device 23 is positioned at a position B and a switching device 26 is positioned at a position D while the cool air in the cold area 5 is discharged to outside of the shop and the air-conditioning machine 21 is operated for room heating and warm air is blown off through a supply duct 40. Thereby, the cool air in the cold area is utilized effectively in accordance with the temperatures four seasons and a load for the air-conditioning machine may be reduced.
