Title:
MULTIPLE-TYPE AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/026025
Kind Code:
A1
Abstract:
This multiple-type air conditioner (100) is provided with a first indoor unit (110A) and a second indoor unit (110B). In a case where the first indoor unit (110A) is stopped and the second indoor unit (110B) operates while a second indoor heat-exchanger (111B) functions as a condenser, when the ratio between a difference between a temperature sensed by a first heat-exchange intermediate temperature sensing unit (112A) and a temperature sensed by a first heat-exchange outlet temperature sensing unit (113A), and a difference between an air temperature and a temperature sensed by the first heat-exchange intermediate temperature sensing unit (112A) is greater than a target value, the opening of a first indoor expansion valve (140A) is increased, and when the ratio is lower than the target value, the opening of the first indoor expansion valve (140A) is decreased.
