Application of Heat Pump Water Heating System with Heat Recovery in Ammonia Refrigeration System

Abstract:

In this paper, a heat pump water heating system with waste heat recovery in ammonia refrigeration system was put forward, based on the practical project analysis of energy demand and waste heat emission. Based on the operating characteristics of ammonia refrigeration system, the ammonia heat exchanger was designed to be installed in series on the ammonia main pipe, which can ensure the system operate efficiently and reliably. Through the analysis of measured data, significant economic benefits had been brought about by using the heat pump water heating system. This project can save 2.19 million RMB in annual operating cost, and the investment recovery period will be only 1.5 years. The heat pump water heating system has excellent development prospect.
