Perspective analysis on TBAB hydrate slurry application in air conditioning system with cool storage

As a new air conditioning two-phase secondary refrigerant,TBAB CHS can significantly reduce the power consumption of cold transport.A method by adding a nuclearing agent to reduce the desired degree of subcooling.The preparation method is simple and efficient,and thermal storage capacity is outstanding.The regenerator temperature is closely correlated with the concentration of the solution and it can be obtained by adjusting the concentration of the solution,the phase transition temperature of consistent with chilled water.According to performance of non-Newtonian fluids,this work summarizes the rheology equation of TBAB hydrate slurry,lists the apparent viscosity and the heat transfer coefficient calculating method,points out the advantages of the TBAB hydrate slurry applied to thermal storage air conditioning.
