Embodiment Construction

[0039] Below, based on figure 1 and figure 2 One embodiment of the radiant cooling and heating device of the present invention will be described. The radiant cooling and heating device 10 of this embodiment is as figure 1 As shown, it has: a ventilation device 12; a primary circuit 14 for cooling and heating; and a secondary circuit 16. First, the primary circuit 14 is provided with a heat source 18 that cools or heats water such as tap water as a heat exchange medium to generate and circulate cold water or hot water. The heat source 18 is, for example, an existing heat source for cooling and heating of a building or for hot water supply. In addition, a primary side circulation line 20 is formed so that water can be circulated to the heat source 18 and piped. The piping members forming the primary side circulation line 20 are made of highly durable metal pipes and the like, and metal parts such as valves are also made of corrosion-resistant materials such as stainless ste...

Abstract

A radiation type cooling and heating device having a primary side circulation pipe path (20) formed so that a heat exchange medium can circulate in it, a heat source (18) provided in the middle of the primary side circulation pipe path (20), a heat exchanger (30) to which the primary side circulation pipe path (20) is connected, a secondary side circulation pipe path (26) as a closed circuit, connected to the heat exchanger (30) and exchanging heat between the primary side circulation pipe path (20) and the heat exchange medium, an expansion tank (62) provided in the middle of the secondary side circulation pipe path (26), a secondary side circulation pump (64) for circulating water, and a radiation panel (40) provided in the middle of the secondary side circulation pipe path (26) so as to face the inside of a room and having a heat exchange pipe (41). The temperature of water flowing in the secondary side circulation pipe path (26) in cooling operation is in the range of 13 - 20 DEG C, preferably in the range of 16 - 18 DEG C, and that in heating operation is in the range of 30 - 40 DEG C, preferably in the range of 32 - 34 DEG C.

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...
