Modular cold and hot water air conditioning unit intelligent joint control system and control method

Abstract

The invention relates to a modular cold and hot water air conditioning unit intelligent joint control system and a control method. According to the system and method, temperature and humidity parameters of indoor and outdoor areas of an office building are acquired, precise group control is performed on the operating power of an air conditioning unit according to the cold (hot) air enthalpy valuesrequired by the office building areas and the work efficiency of the air conditioning unit, the optimal energy consumption operating mode is established by means of the unique power-saving intelligent control procedure based on acquired data including the operating temperature, pressure, flow rate and the like of the air conditioning unit as well as a series of parameters such as the height, orientation, materials, the thermal load, indoor and outdoor temperature and humidity conditions of the building and the user using habit, building load variation is automatically tracked, dynamic predicting, advanced adjustment and synchronous optimization are achieved, finally, the central air conditioning parameters of temperature, pressure, flow rate and the like are adjusted, the power curve is made to approach the power curve required by an actual load as close as possible under the condition that the requirements of an end system for the temperature, pressure, flow rate and the like are met, the energy-saving effect of air conditioners is pushed to the limit, and the purpose of system energy-saving optimization is achieved.

Description

technical field [0001] The invention belongs to the technical field of central air-conditioning, in particular to an intelligent joint control system and control method of a modular cold and hot water air-conditioning unit. Background technique [0002] At present, most office buildings and office buildings use modular air-cooled cold (hot) water air conditioning units to provide cooling in summer and heating in winter. There are nearly 8 months of continuous working time throughout the year. [0003] The existing air-conditioning unit has a simple control process, and only operates according to the set power without considering the use of the air-conditioning area, and it is impossible to accurately control the operation of the air-conditioning unit according to the required air enthalpy. As a result, the power consumption of the air conditioning unit is high, which does not meet the needs of energy saving. Contents of the invention [0004] The purpose of the present i...
