Abstract

PURPOSE:To maintain comfortable air conditioning by supplying outside air into an air conditioning space in a room from a bypassing path without heat exchange when a room temperature is higher than a set value in the heating operation. CONSTITUTION:In the heating operation, when the temperature of 2 dwelling room 1 rises by a specified value from the set temperature with a room temperature setting device 17, a fully closing signal is transmitted to a cold/hot water valve 5 from a control panel 10 of an air conditioner while a ventilation command using no total heat exchanger is transmitted to a control panel 11 of the total heat exchanger where the temperature of the air circulated as measured with a circulated air temperature sensor 15 is higher than the temperature of outside air as measured with an outside air temperature sensor 16 and the temperature of the outside air as measured with the outside air temperature sensor 16 is higher than the set temperature in a room. Then, a control panel 11 of the total heat exchanger transmits an opening signal to a total heat exchange bypass damper 14 and an exhaust damper 12 and a fully closing signal to an outside air damper 13 to perform a ventilation using no total heat changer 3. This prevents excessive rise in the room temperature thereby enabling the maintaining of comfortable environment in the room.
