Abstract

The invention discloses a novel adsorption bed and a solar refrigeration system applying the same, and belongs to the technical field of refrigeration equipment. The solar refrigeration system consists of a trough collector, a heat accumulator, an adsorption refrigeration system, a cooler, a collector control valve, an adsorption bed control valve, a circulating pump I, a circulating pump II, a three-way diverter valve I and a three-way diverter valve II. The adsorption bed is applied to the adsorption refrigeration system, and comprises an adsorption bed outer shell, a U-shaped tube, fins, an evaporator connector, a condenser connector, a pressure gage, a temperature sensor and an adsorption bed support plate. As the trough solar collector system is adopted as a heat source of the adsorption bed, conduction oil can be heated to 180-220 DEG C, so that an adsorbent on the adsorption bed can be deeply resolved, and the refrigerating capacity of unit refrigeration steam is increased. As the adsorption bed body is of a fin tubular structure, the heat transfer efficiency is effectively improved.

Description

Technical field [0001] The invention relates to a novel adsorption bed and a solar refrigeration system used, in particular to a medium-high temperature refrigeration using solar energy, and belongs to the technical field of refrigeration devices. technical background [0002] Environmental and energy issues have always been major issues facing social development. With the improvement of people's living standards, the requirements for environmental comfort continue to increase, which increases the demand for air conditioning in summer. This not only aggravates the warming of the global climate, the destruction of the ozone layer, and the shortage of energy sources, but also increases the electricity load during peak electricity consumption in summer. Solar refrigeration technology can effectively alleviate these problems, which is in line with the current general trend of coordinated development of energy and environment. [0003] In the past 20 years, the adsorption refri...
