Description

technical field

[0001] The invention relates to a radiant cooling and heating device for cooling and heating a room through a radiant panel emitting radiant heat through fluid circulation. Background technique

[0002] Conventionally, as a cooling and heating device for cooling and heating a room, generally, an air conditioner using an air conditioner instead of Freon (Fron) gas as a refrigerant is known. A device that blows cold or warm air from the outlet to the room for cooling and heating.

[0003] Furthermore, Patent Document 1 discloses an apparatus that uses water as a secondary refrigerant to generate hot and cold water in a heat source unit. In this device, the high-temperature and high-pressure refrigerant gas discharged by the compressor is condensed and liquefied through the air-side heat exchanger, and the refrigerant liquid is decompressed by the expansion valve to form a two-phase liquid in the liquid phase and gas phase, and passes through the water-side hea...
