Application of night radiant cooling to ground-source heat pumps

Aiming at the performance degradation of ground-source heat pump technology used in cooling load dominant buildings, puts forward a new ground-source heat pump hybrid system with auxiliary night radiators. Designs a night radiator, constructs an analytical solution model of night radiator and new hybrid system, and compiles the corresponding system operating simulation program. Taking a small residential house in Hong Kong as an example, designs a new type of ground-source heat pump hybrid system, and simulates its operating performance and energy consumption. Based on the calculation results, analyses the feasibility of the application of night radiant cooling technology to the ground-source heat pump.
