Investigation on Waste Heat Recovery from the Condenser of Air Conditioning System

Abstract

In the era of globalization, the conservation of energy has become important. Refrigeration is a process in which heat is removed from low temperature body to high temperature body. Heat rejected from the condenser of refrigeration system possess considerable amount of energy. In this work, an effort is initiated to recover the desolated heat from the condenser and used to heat the water and supplied to the washroom, cleaning, etc. The main aim of this project is to reduce the losses and to recover waste heat of the condenser. A heat exchanger of shell and tube was used and replaced the air cooled condenser. A mathematical model also presented for replacing a water-cooled condenser in spite of an air-cooled condenser. The temperature of water at the exit of heat exchanger lies in the temperature range of 44 to 480C. The proposed waste heat recovery system increases the overall Coefficient of Performance (COP) of the system. The objective of this work is to develop a system that can recover waste heat from the condenser unit of refrigeration system. Process and mathematical model for changing air-cooled condenser into water cooled condenser have also been presented. The proposed system has no notable effect on refrigeration with integration; and which increases the performance of refrigeration system.
