Application Analysis of Distributed Electric Heating System

Abstract

The population of the world is increasing daily and people desire a high standard of life. As a result ， distributed electric heating system, a air source heat pump and solar thermal combined system, will be widely used for space heating as an energy efficient and environment friendly way. In this paper distributed electric heating system is designed. The system can produce hot water for heating by recovering energy from solar energy and air source. Solar collector contained 50 glass vacuum tubes. And collector area is 7.7m2.. Heating capacity of air-source heat pump unit is 10.6kW. Distributed electric heating system is run for three days. the result shows that the system can meet the need of space heating.
