Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2011/104834
Kind Code:
A1
Abstract:
In order to exert cooling and heating abilities using a natural circulation cycle heat exchanger as the heat exchanger of a pressure cycle, the disclosed air conditioner has a configuration that can form at least three refrigeration cycles: a natural circulation cycle (TS1) formed in a loop by sequentially connecting with pipework a first heat-source-side heat exchanger (4), a first expansion valve (5), and a first use-side heat exchanger (6); a first pressure cycle (PC1) formed in a loop by sequentially connecting with pipework the discharge port (1b) of a compressor (1), a duct switching valve (2), a second heat-source-side heat exchanger (7), a second expansion valve (9), a second use-side heat exchanger (8), and the intake port (1a) of the compressor; and a second pressure cycle (PC2) formed in a loop by sequentially connecting with pipework the discharge port (1b) of the compressor, the duct switching valve (2), the second heat-source-side heat exchanger (7), the first heat-source-side heat exchanger (4), the first expansion valve (5), the first use-side heat exchanger (6), the second use-side heat exchanger (8), and the intake port (1a) of the compressor.
