Method and system for recovering energy from air conditioners in commercial complexes

Abstract

The invention discloses a method set system for recovering air-conditioning energy in a commercial complex. The commercial complex includes an office building and a shopping mall. The office building adopts a water source VRF air-conditioning system, and the shopping mall adopts a chiller central air-conditioning water system; The device transfers the calorific value in the shopping mall to the office building, and uses it as supplementary heat for the water source VRF air conditioning system, thereby avoiding or reducing the running time of boilers, shopping mall cooling towers, and refrigerators that turn on the water source VRF air conditioning system of the office building, and can greatly save energy consumption , reduce operating costs. The invention avoids or reduces the running time of turning on the boiler, the cooling tower, and the refrigerator, can greatly save energy consumption, and reduce operating and maintenance costs.

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
