Summary:

This book examines the design technologies and developments in refrigeration systems. Topics discussed include sorption refrigeration systems; improving the performance of heat pumps in air-conditioning plants by using membrane contactor dehumidification/regeneration systems; the correct size of the condenser as one of the significant issues for the optimal performance of refrigerating and air conditioning systems; prototyping and experimental evaluation of an air filtration system; and irreversible estimation possibilities of an absorption refrigeration cycle.
