Abstract: This paper presents the characteristics of the double cold and heat source system adopting screw chillers and air-source heat pumps, and the design and the hydraulic calculation method of the ring pipe network. This paper analyses the hydraulic characteristics of pipe network under the separate operation, and the hydraulic condition under the joint operation of screw chillers and air-source heat pumps. The advantages and disadvantages of the temperature difference control of total supply and return water and the energy saving rate are presented.
Keywords: air-source heat pump; vertical ring pipe network; joint operation; resistance of pipe network; control strategy;
