Embodiment Construction

[0022] As shown in the figure, a refrigerant hydrate circulating cold storage system includes a hydrate reaction tank 1, an absorber 7, a solution pump 12, a generator 15, a condenser 21, and DMF solvent and refrigerant R134a running in the entire system The formed mixed liquid, wherein, the upper and lower parts of the absorber 7 are respectively provided with a solvent spray nozzle 8 and a refrigerant hole tube 11, and the DMF solvent and refrigerant R134a pass through the solvent spray nozzle 8 and the refrigerant hole tube respectively 11 After spraying, a mixed solution is formed at the filler layer I9 in the absorber 7, and is pumped into the generator 15 by the solution pump 12, and sprayed on the filler layer II17 in the generator 15 by the mixed solution nozzle 18. The generator 15 is provided with a heating device 16 for heating the mixed solution after spraying, so that the refrigerant R134a in the mixed solution evaporates to generate R134a vapor, and the vapor pres...

Abstract

The invention discloses a refrigerant hydrate circulating cool storage system. The refrigerant hydrate circulating cool storage system comprises a hydrate reaction barrel, an absorber, a solution pump, a generator, a condenser and mixed liquid which is formed by a DMF solvent and an R134a refrigerant and is operated in the whole system. The DMF solvent and the R134a refrigerant form a mixed solution in the absorber, and the mixed solution is pumped into the generator through the solution pump. R134a steam is generated in the generator, enters an evaporator coil located in the hydrate reaction barrel after being cooled and liquefied through the condenser so as to provide cooling capacity for hydrate reactions and then returns to the absorber, the residual solution in the generator also returns to the absorber to be mixed again. According to the refrigerant hydrate circulating cool storage system, hydrates melts to absorb heat at the high temperature by day so as to achieve the purpose of cooling a room, and waste heat or low-price electric energy is used for achieving the purpose of refrigerant gas hydrate cool storage by night through the cool storage circulating system.

Description

technical field [0001] The invention relates to the field of industrial refrigeration, in particular to a refrigerant hydrate circulation cold storage system. Background technique [0002] Due to the improvement of people's living standards, air conditioners are becoming more and more popular. However, due to the high energy consumption of air conditioners, the concentrated use of air conditioners has caused the gap between peak and valley electricity consumption in cities to increase day by day. In order to cut peaks and fill valleys of the power grid, energy storage air conditioners are now being advocated. A better option is to use ice storage systems, which can save a lot of operating costs for users. However, the ice storage system also has its own disadvantages. For example, the initial investment is large, and the refrigeration unit has a very low evaporation temperature during ice production, and its COP is reduced. Therefore, from the perspective of energy saving, ...
