Abstract

The invention relates to an energy storage solar ejection refrigeration device by adopting the solar energy to refrigerate, comprising a solar thermal collector, a water pump and a generator which form a circulation loop together with the solar thermal collector, a refrigerating medium circulation loop which exchanges the heat with the generator and consists of an ejector, a condenser and the refrigerating medium which are connected in series, a refrigerating medium circulatory refrigeration loop consisting of a throttling valve, an evaporator, the ejector and the condenser and an air conditioning circulatory refrigeration loop consisting of an air conditioning water pump and the evaporator, wherein, in the air conditioning circulatory refrigeration loop, a cold water loop is provided with a three way valve F6 and a valve F1, a cold water supply pipeline is provided with a valve F2 and a three way valve F4, an ice storage tank is arranged on a pipeline between the three way valve F6 and the three way valve F4, a pipeline between the valve F2 and the three way valve F4 is communicated with the ice storage tank by the valve F3, a pipeline between the ice storage tank and the three way valve F4 is also provided with a valve F5. The solar energy utilization ratio is increased by more than 30 percent, the cooling capacity is increased by more than 20 percent, 'the peak shifting and valley filling' of the solar energy is realized and the electric fence load is lightened.

Description

technical field [0001] The invention relates to an energy storage type solar jet refrigeration device for cooling by using solar energy, which is suitable for the field of air conditioning and refrigeration. Background technique [0002] With the aggravation of energy crisis, the utilization of solar energy has been paid more and more attention by people. In the solar energy utilization technology, the solar jet refrigeration system is favored by everyone for its simple structure, few moving parts, and low cost, and it is more and more widely used in the field of air conditioning and refrigeration. The operation effect of the traditional solar jet refrigeration system is mainly restricted by two factors: one is the variation of solar radiation intensity, and the other factor is the variation characteristics of the cooling load of the air conditioner at the user end. The time-to-hour changes of the two are not completely consistent, and it is difficult for the traditional je...

Problems solved by technology

The time-to-hour changes of the two are not completely consistent, and it is difficult for the traditional jet refrigeration system to achieve a balance between the supply and demand of the two, that is, when the solar radiation is sufficient, as long as the cooling capacity provided by the jet refrigeration system is greater than the load required by the air conditioner, It will inevitably lead to low utilization rate of solar energy; in addition, when the night or when the solar radiation is insufficient, the cooling capacity provided by the solar jet refrigeration system cannot meet the needs of the air conditioning load.
