Suitability study of seawater source heat pump system utilizing buried capillary network heat exchanger
Seawater source heat pump systems face problems such as biological attachment,pipe corrosion and heat exchanger icing in severe cold weather,which affect its coefficient of performance(COP).The seawater source heat pump system which utilizes capillary net-work heat exchanger made of PP-R and buried in the sandy soil of sea bed can effectively a-void the above problems.Based on energy consumption simulation data,this study compares the economy and environmental friendliness of seawater source heat pump system,air source heat pump system and the chiller+gas boiler system.The results show that the economic and environmental benefits of the seawater source heat pump system with the buried capillar-y network heat exchanger are optimal.With 20 years of system operation,the whole life cycle cost of the seawater source heat pump system is 4.595 million RMB,with a minimum annual cost of 468 000 RMB,and its carbon emissions per unit area over the life cycle of the building are 10%lower than that of the air source heat pump system and 21%lower than that of the chiller+gas boiler system.This study provides consumers with a better understanding of the seawater source heat pump system and provides data to support the promotion of its application.
