Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2010/128557
Kind Code:
A1
Abstract:
Provided is a multi-chamber air conditioner which can perform simultaneous cooling and heating operations while preventing refrigerant having a risk of influence on human body from leaking into rooms where indoor units are installed, and can prevent degradation in performance due to a refrigerant flow controller or degradation in cooling performance of the indoor units.
A multi-chamber air conditioner comprises a heat source side refrigerant circuit (A) where a compressor (11), an outdoor heat exchanger (13), a second refrigerant flow controller (25b), a first intermediate heat exchanger (21), a first refrigerant flow controller (25), a second intermediate heat exchanger (22), and a third refrigerant flow controller (25c) are connected in series; and a utilization side refrigerant circuit (B) where the first intermediate heat exchanger (21) and the second intermediate heat exchanger (22) are connected in series, respectively, with each indoor heat exchanger (31). The first intermediate heat exchanger (21) and the second intermediate heat exchanger (22) perform heat exchange between a heat source side refrigerant circulating through the heat source side refrigerant circuit (A) and a utilization side refrigerant circulating through the utilization side refrigerant circuit (B).
