Method for acquiring optimum air-conditioning system operation parameters based on weather forecast

Abstract

The invention relates to a method for acquiring the optimum air-conditioning system operation parameters based on the weather forecast, solving the problems of poor temperature regulating quality in the buildings because of inaccurate operation parameters of the existing air-conditioning systems and difficult implementation and grave energy waste because of higher requirements of the existing automatic air-conditioning regulating devices for the existing air-conditioners. The method is characterized by computing the hourly meteorological parameters of the next N-numbered hours according to the weather forecast in combination with the historical meteorological data; later, computing the hourly air-conditioning load according to the characteristic parameters of the buildings in combination with the hourly meteorological parameters and comparing the hourly air-conditioning load with the designed air-conditioning load to determine the hourly load coefficients; then carrying out heat balance analysis on all the operation modes and the hourly load coefficient of the air-conditioners to be regulated to screen out the feasible operation modes; and selecting the feasible operation mode characterized by minimum energy consumption as the optimum operation mode and outputting the parameters of the optimum operation mode. The method is applicable to operation control of large air-conditioners.

Description

technical field [0001] The invention relates to a method for obtaining operating parameters of an air conditioning system. Background technique [0002] In most of the existing air-conditioning systems, due to construction time, design, initial investment, and management reasons, the operating parameters of the air-conditioning are obtained through manual meter reading and calculation, and the operating parameters are not accurate. The data adjusts the air conditioning to meet the needs of the building's thermal comfort. Under this kind of operation control of the air conditioning system, the cooling capacity provided by the chiller is difficult to adapt to the change of the building load, and the quality of thermal comfort in the building is poor. [0003] However, the existing air-conditioning automatic adjustment devices, such as the direct digital control system (DDC system), although the air-conditioning system can realize the temperature adjustment according to the te...
