Title:
INDOOR AIR-CONDITIONING SYSTEM, INDOOR AIR-CONDITIONING METHOD USING IT, AND AIR-CONDITIONING UNIT
Document Type and Number:
Japanese Patent JP3432740
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the unbalance of the amount of wind and pressure in a room, and at the same time to effectively perform air-conditioning by connecting a second fresh air intake to an exhaust channel for connecting indoor and outdoor exhaust vents, and by sucking the amount of lacking ventilation to the indoor exhaust vent from the second fresh air intake to the exhaust channel for replenishment.
SOLUTION: A second fresh air intake 11 is connected to the upstream side of a sensible heat exchanger 18 of an exhaust channel 15 for connecting indoor and outdoor exhaust vents 9 and 10, and is connected to space under a floor. For example, when the operation of a range hood is switched to independent one for setting a medium or strong position for cooking, an exhaust value from the range hood is increased, and the amount of ventilation to the indoor exhaust vent 9 of an air- conditioning unit 6 is decreased by the exhaust value. The amount of suction and replenishment of air under the floor from the second fresh air intake 11 is decreased by the amount of decrease in the amount of ventilation, thus preventing the unbalance of the amount of wind and pressure in a room before and after switching, and continuing comfortable air-conditioning without allowing cold air with high humidity to enter a room in winter and rainy season, respectively.
