| As a new type of cool storage medium,gas hydrate has a good application prospect in air conditioning.The dissociation heat,one of the important thermal physical properties,is necessary to the designing of cool storage system.Recent advances in the dissociation heat of gas hydrate is presented in this paper.This work lists the calculated and measurement methods of the dissociation heat and elaborates the main factors affecting the dissociation heat and corresponding mechanism.This paper points out that the gas concentration and additive concentration have the effect on the dissociation heat.And the dominant factor that influences the dissociation heat of the hydrate is gas molecular diameter.The study on the dissociation heat provides the theoretical basis for the exploitation,the hydrate stability study,and the storage system design. |
