Radiation air conditioner

Technical Field

The invention relates to the field of air conditioners, in particular to a radiation air conditioner.

Background

The existing conventional air conditioner blows out wind, when the temperature of a human body is higher, the moisture of the human body is taken away through wind circulation, so that heat is taken away, and the heat dissipation wind quantity of the direct blowing type air conditioner directly acts on the skin of the human body, can cause pores to shrink sharply or expand sharply, is not beneficial to perspiration and heat dissipation of the human body or heat absorption of the human body, and is the key for regulating the temperature of the human body in the most comfortable temperature environment which is most beneficial to the health of the human body. How to effectively avoid heat exchange of human bodies, radiation type air conditioners are available in the market, and radiation cold/warm supplying refers to a technical scheme of reducing/increasing the temperature of one or more surfaces in the inner surface of an enclosure structure to form a cold/heat radiation surface, and supplying cold/warm by means of heat exchange between the radiation surface and the radiation of the human bodies, furniture and other surfaces of maintenance structures. The radiating surface can be realized by arranging a cold/hot pipeline in the maintenance structure, and can also be realized by adding radiation on the outer surface of a ceiling or a wall. In the technology, the radiation heat exchange amount accounts for more than 50% of the total heat exchange amount generally because the radiation surface and the temperature of the maintenance structure and the furniture surface are changed, so that the convection heat exchange between the radiation surface and the space is enhanced, and the cold/warm supply effect is enhanced.

The radiation air-conditioning system is a hidden air conditioner, can be laid on the top surface, the wall surface and the ground, and has lower water supply temperature and correspondingly lower energy consumption compared with the traditional method for radiation heating and energy saving; moreover, heat pump, solar energy, geothermal energy and low-grade heat energy can be used, so that energy can be further saved; the comfort strong radiation heating improves the indoor average radiation temperature, greatly reduces the radiation heat dissipation of human bodies, enhances the comfort of the human bodies, and because the room temperature can be lower than that of a radiator, the indoor air is not dry.
