Commercial complex air-conditioning energy recycling method and system

Abstract

The invention discloses a commercial complex air-conditioning energy recycling method and system. A commercial complex comprises office buildings and malls, the office buildings adopt a water source VRF (variable refrigerant flowrate) air conditioning system, and the malls adopt a water chiller central air conditioning water system; heat value in the malls is transferred to the office buildings through plate heat exchangers, and the water source VRF air conditioning system is supplemented in heat and used, so that running time of boilers used for starting the water source VRF air conditioning system of the office buildings and cooling towers and refrigerators of the malls are avoided or reduced, energy consumption can be greatly saved, and running cost is lowered. The running time for the boilers as well as the cooling towers and refrigerators is avoided or reduced, so that energy consumption can be greatly saved, and running and maintaining costs are lowered.

Description

technical field [0001] The invention relates to a commercial complex air-conditioning control method and system, in particular to a commercial complex air-conditioning energy recovery method and system in cold weather. Background technique [0002] Commercial complexes are generally formed by office buildings and shopping malls. Office buildings use water source VRF (Variable (variable) Refrigerant (refrigerant) F–Flow / Volume (flow)) air-conditioning systems, and shopping malls use chillers and central air-conditioning water systems. Since the office building needs to be heated in winter, and the heat generated by people and lights in the shopping mall forms a stable heat (cooling load), even in winter, it is still necessary to turn on the electric compression chiller or cooling tower for cooling. Therefore, usually in winter, the two systems need to be operated independently, that is, the office building needs to start the boiler to supplement heat for the water source VRF ...

AI Technical Summary

Problems solved by technology

Therefore, usually in winter, the two systems need to be operated independently, that is, the office building needs to start the boiler to supplement heat for the water source VRF air-conditioning system, while the shopping mall needs to start the refrigerator or cooling tower for cooling, and the equipment is used more. The consumption is high, the operating cost increases, and because the equipment needs to run for a long time, it affects the service life and increases the maintenance cost
