A new rating method for heat exchangers using refrigerant with temperature glide.

Author(s) : COLBOURNE D., SUEN K. O.

Summary

Conventional refrigeration evaporator and condenser rating methods use fluid inlet temperatures and corresponding capacity to obtain a basic rating for the specific unit. The basic rating is normally defined as the capacity divided by the difference between inlet heat transfer fluid and the evaporating temperatures, and is applied to a range of conditions in order to obtain the heat exchanger characteristic. This method is acceptable for use with pure refrigerants but the application of a multi-component refrigerant with temperature glide results in a non-constant basic rating. The paper offers a modified method that will provide improved accuracy to the characterisation of refrigeration evaporators using refrigerants with temperature glide.
