Summary

A panel system for cooling buildings is proposed, working with an absorption-refrigeration unit, the evaporator of which is the panel itself. Trifluoroethanol (TFE) and N-methylpyrrolidinone (NMP) are proposed as refrigerant and absorbent, respectively. Use of the TFE-NMP mixture seems to offer advantages over the usual water-lithium bromide or ammonia-water mixtures, and suits well the modest refrigeration temperatures needed in panel cooling. Analytical expressions are presented for the properties of the TFE-NMP mixture and a calculation procedure for ammonia-water units is used after suitable modifications to simulate the operation of the TFE-NMP absorption-refrigeration unit.
