Evaluation of the Performance of a Ground-Water Heat Pump System in Hot-Summer and Cold-Winter Region

Article Preview

Abstract:

This study presented the energy performance evaluation of a ground-water heat pump (GWHP) system based on actual operational data. The GWHP system was installed for apartment buildings in Wuhan, China. During one year, various operating parameters of the GWHP system were monitored and the coefficient of performance (COP) of system was determined based on the measurement. The energy consumption of the GWHP system is more than twice the average value of split air conditioner on residential application, because of continuously operating of the GWHP system and frugally intermittence operating of split air conditioner. The GWHP system is more economical than other central system. The energy savings rate of the GWHP system was 41.5% for the heating season comparing with boiler and 42% for the cooling season comparing with air source heat pump.
