AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2012/060227
Kind Code:
A1
Abstract:
This air conditioner appropriately controls the temperature of a radiant panel (radiant heat exchanger). The air conditioner has a compressor (60), an outdoor motor-operated valve (64), an outdoor heat exchanger (62), an indoor heat exchanger (20), and a radiant panel (30), and is provided with a coolant circuit (10) that is configured in a manner so that high-temperature coolant flows to the radiant panel (30) during a radiant heating operation. During the radiant heating operation, a panel-entry-temperature sensor (25) is provided to the piping upstream from the radiant piping of the radiant panel (30), and a panel-exit-temperature sensor (26) is provided to the piping downstream from the radiant piping of the radiant panel (30). An indoor motor-operated valve control unit controls an indoor motor-operated valve (23) provided upstream from the radiant piping of the radiant panel (30) on the basis of the temperatures detected by the panel-entry-temperature sensor (25) and the panel-exit-temperature sensor (26).
