Document Type and Number:
WIPO Patent Application WO/2012/107947
Kind Code:
A1
Abstract:
An air-conditioning device (100) capable of a heating operation and having a cooling medium circulation circuit A, for which a compressor (10), a cooling medium flow path switching device (11), a cooling medium flow path for an inter-heating-medium heat exchanger (15) that exchanges heat between the cooling medium and the heating medium, a throttle device (16), and a heat source-side heat exchanger (12) are connected with cooling medium pipes to form a refrigeration cycle, and having a heating medium circulation circuit B, which is formed by connecting with heating medium pipes a heating medium flow path for the inter-heating-medium heat exchanger (15), a pump (21), and a usage-side heat exchanger (26). In addition, the air-conditioning device has: an opening/closing device (28), which is provided on a heating medium supply pipe (38) that supplies to the heating medium circulation circuit B a heating medium from outside of the circuit B, and which passes or blocks the flow of heating medium from the heating medium supply pipe (38) to the heating medium circulation circuit B; and air discharge devices (27), which are provided in the heating medium circulation circuit B, and which discharge residual air in the heating medium circulation circuit B. The heating operation is performed while the opening/closing device (28) and the air discharge devices (27) are open.
