AIR CONDITIONER AND RELAYING DEVICE

Document Type and Number:

WIPO Patent Application WO/2010/049998

Kind Code:

A1

Abstract:

An air conditioner which does not circulate the refrigerant to an indoor unit, saves energy and can be easily installed. A refrigeration cycle circuit is constituted by connecting a compressor (10), a four-way valve (11), a heat source side heat exchanger (12), expansion valves (16a-16e) and intermediate heat exchangers (15a, 15b) through piping, and a heating medium circulation circuit is constituted by connecting the intermediate heat exchangers (15a, 15b), pumps (21a, 21b) and utilization side heat exchangers (26a-26d) through piping. An outdoor unit (1) is installed in a space, e.g. outdoor of a building (9), and houses the compressor (10), the four-way valve (11) and the heat source side heat exchanger (12). A relay unit (3) is provided in a space (8), which is not to be air-conditioned and is different from the indoor space (7) in the installation floor separated by a plurality of floors from an outdoor unit and houses the expansion valves (16a-16e), the pump (21) and the intermediate heat exchangers (15a, 15b). The outdoor unit and the relay unit are connected by two pipings. The relay unit (3) and an indoor unit (2), which houses the utilization side heat exchangers (26a-26d) and located at a position capable of air-conditioning the indoor space (7), are connected by two pipings from the outside of a wall partitioning the indoor and the outdoor.
