Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/132377
Kind Code:
A1
Abstract:
An air conditioning device comprising a refrigerant circulation circuit (A), a heat medium circulation circuit (B), and a heat medium converter control device (52) that circulates a heat medium through the heat medium circulation circuit (B) and executes a replacement operation whereby attached matter that has attached inside the heat medium circulation circuit (B) is stripped away. The refrigerant circulation path (A) comprises, connected by pipes: a compressor (10) that compresses a heat source-side refrigerant; a first refrigerant flow path switching device (11) for switching the circulation path for the heat source-side refrigerant; a heat source-side heat exchanger (12) for exchanging heat source-side refrigerant heat; a throttle device (16) for adjusting the pressure of the heat source-side refrigerant; and an inter-heat-medium heat exchanger (15) that exchanges heat between the heat source-side refrigerant and a heat medium that differs from the heat source-side refrigerant. The heat medium circulation path (B) comprises, connected by pipes: a pump (21) for circulating the heat medium pertaining to heat exchange by the inter-heat-medium heat exchanger (15); a usage-side heat exchanger (26) that exchanges heat between the heat medium and air for the space to be air conditioned; and flow path switching devices (22, 23) that switch between passage, to the usage-side heat exchanger (26), of heat medium that has been heated and heat medium that has been cooled. The heat medium circulation path (B) has a strainer (61) that captures foreign matter in the heat medium.
