Abstract

The invention discloses a solar double-adsorption-bed and enhanced mass recovery continuous circulation refrigerating system. The system comprises a water bath type adsorption refrigerating system, adirect heating type adsorption refrigerating system and a solar heat storage system. One end of the water bath type adsorption refrigerating system communicates with the direct heating type adsorptionrefrigerating system, and the other end communicates with the solar heat storage system. According to the system, the utilization rate of solar energy can be effectively improved, the workload of a solar heat collector is reduced, and the heat collection area of the heat collector is effectively reduced, so that the cost is reduced, day-and-night continuous refrigeration cycle can be realized, the quantity of refrigerants participating in the cycle is greatly increased through double-bed mass recovery, enhanced mass recovery and enhanced desorption, and the refrigerating efficiency is effectively improved.

Description

Technical field [0001] The invention relates to the technical field of new energy refrigeration, and more specifically to a solar energy double adsorption bed enhanced mass recovery continuous cycle refrigeration system. Background technique [0002] As a green, pollution-free and clean energy, solar energy is different from petroleum, coal, etc., and does not produce the "greenhouse effect". Moreover, the amount of radiation reaching the surface of the earth every year is very huge, and its total amount is now the largest energy that can be developed on the earth. Today, when green, coordinated and sustainable development is advocated, solar energy has received more and more attention and its application widely. At present, the technology of solar energy in heat utilization, such as solar water heater, is becoming more and more mature. Solar adsorption refrigeration is also developing rapidly, and it has been used in the refrigeration of fruits and vegetables, refrigeration sy...

AI Technical Summary

Problems solved by technology

[0006] However, both the water-bath adsorption bed and the direct heating adsorption bed have some disadvantages: for example, the utilization rate of solar energy is not high, continuous refrigeration is not possible, the refrigeration efficiency and cooling capacity are not high, and the single cycle time is long, etc.

The water-bath adsorption bed stores solar energy during the day, and then uses it for the desorption of the adsorption bed at night, but the adsorption bed also needs to be desorbed by heat during the day, so the burden on the solar collector is relatively large, and the heat collection area of ​​the collector needs to be increased And the scale of the heat storage system, which directly increases the cost, but reduces the cooling efficiency

The direct heating adsorption bed combines the heat collector and the adsorption bed to directly absorb solar radiation to heat the adsorption bed, but at night, it can only perform adsorption and refrigeration, and cannot perform the next cycle, so the time at night is wasted. The overall utilization of the system is not high
