Energy conservation and environmental protection evaluation of river water-source heat pump district cooling and heating systems

Taking the river water as cold and heat sources of water-source heat pumps for building cooling and heating has good energy conservation and environmental protection significance. Puts forward an evaluation method for synthetically analysing the primary energy utilization rate, the influence of district cooling and heating radius on energy consumption of the system, and the energy conservation and environmental protection value of unit flux. States that the heat pollution problem should be considered when evaluating the environmental performance of water-source heat pump systems.
