Abstract
This paper presents a new heat pump system in which tunnel air is served as air source. In this heat pump system, tunnel air acts as a heat source from which heat is extracted during heating, and as a heat sink to which heat is rejected during cooling. Coefficient of performance of the heat pump is always high because the temperature of tunnel air in summer is lower than that of atmosphere air, whereas that of tunnel air in winter is higher that of atmosphere air.
Energy consumption of heat pumps in which atmosphere air and tunnel air is respectively served as source is compared and analyzed. Results show that tunnel air-source heat pump systems are energy efficient cooling/heating system and the heating capacity of air-source heat pumps is free from drop in winter.
