Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2012/101676
Kind Code:
A1
Abstract:
An air conditioner capable of saving energy by using energy efficiently, even if a non-azeotropic refrigerant mixture is used, is provided. The air conditioner (100) is provided with: a heating medium flow rate regulating device (25) that regulates the flow rate of a heating medium circulating in utilization-side heat exchangers (26); a temperature sensor 34 and a temperature sensor 31 that are disposed on an input-side flow path and an output-side flow path of the utilization-side heat exchangers (26), and that detect the temperature of the heating medium; and a control device (60) that controls the heating medium flow rate regulating device (25) in such a manner that the temperature difference between the detected value of the temperature sensor 34 and the detected value of the temperature sensor 31 reaches a target value. A refrigerant that flows through a refrigerant-side flow path of inter-heating-medium heat exchangers (15) flows counter to the heating medium that flows through a heating-medium-side flow path of the inter-heating-medium heat exchangers, and the control device (60) changes the first target value in response to the operating state of a refrigerant circulation circuit (A).
