Techno-economic Analysis on Water Source Heat Pump System

Water-source heat pump system is an air-conditioning device using water as heat source/heat-exhaust source for heating/cooling cycle. The relative stabilization of water temperature ensures the higher coefficient of performance (COP). Using water-source heat pump system can reduce the pollution emission, which is benefit for the environment. Comparing with the traditional systems for heating and cooling, the investment and operating costs of the water-source heat pump system is lower and the system can be a multi-purpose machine for heating, air-conditioning and the provision of domestic hot water. Water-source heat pump system has the advantages of running stably and control and maintenance expediently. So the water-source heat pump system should be promoted as green environmentally friendly products.
