Cold-accumulation and cold-supply integrated radiation heat exchange plate used for solar air conditioner

Abstract

The invention discloses a cold-accumulation and cold-supply integrated radiation heat exchange plate used for a solar air conditioner. The cold-accumulation and cold-supply integrated radiation heat exchange plate comprises a metal box, a metal coil pipe, a liquid adding opening and phase-change materials; the metal box comprises a top and a bottom, the metal coil pipe is arranged on the outer surface of the top and is in close contact with the outer surface of the top, and the liquid adding opening is formed in the middle of the outer surface of the top, penetrates through the top and extends to the exterior of the metal box; the phase-change materials are arranged inside the metal box. According to the cold-accumulation and cold-supply integrated radiation heat exchange plate, the characteristics, of the high phase-change latent heat and the constant solidification / melting temperature, of the phase-change materials are sufficiently used, the dew formation problem, caused by the instability of solar cold supply, of the radiating plate is effectively solved, and meanwhile the cold accumulation effect and the cold supply effect are achieved.

Description

technical field [0001] The invention relates to a radiation heat exchange plate for a solar air conditioner, in particular to a radiation heat exchange plate for a solar air conditioner with integrated cold storage and cooling, which belongs to the field of air conditioning radiation and cooling terminals. Background technique [0002] Modern building air-conditioning systems have high requirements in terms of energy saving, environmental protection and comfort. Solar air-conditioning has attracted much attention because of its advantages of energy saving, environmental protection and good seasonal adaptability. However, the COP of the solar air-conditioning system is very low whether using the adsorption chiller or the absorption chiller. For this reason, solar air conditioners are often used in high-temperature cooling systems to improve the COP of refrigerators. In the high-temperature cooling system, the radiation heat exchange system has the advantages of good thermal ...
