【Abstract】 A new ground source heat pump water heater system is designed,and the system architecture,the system flow dia- gram and the principle of the system are introduced separately in this paper.And through the simulation of the operating condition of the ground-source heat pump water heater system working under the mode of making hot water in winter,the changes for the system performance parameters with the cooling water outlet temperature and the cooling water outlet temperature with the time are studied,and the results show that the change range of COP is 3.16～4.33,and in a short period,the cooling water outlet tem- perature can reach 61.66℃,because of which the system has high efficiency,stability and energy saving.The paper provides the designing reference to the promotion and use of ground source heat pump water heater system.更多还原
