Embodiment

[0026] hardware composition

[0027] The data acquisition unit is composed of temperature sensor, humidity sensor, pressure sensor and flow sensor, etc. The temperature acquisition adopts Pt100, and the acquisition of pressure and humidity adopts sensors that support 0-10V / 4-20mA standard signals.

[0028] The central controller adopts OMRON's CJ1M series programmable controller, in which the CPU unit selects CJ1M-CPU12, the power supply module selects CJ1W-PA205R, and the analog input and output modules respectively select CJ1W-AD081-V1 and CJ1W-DA08V switch input and output Choose CJ1W-ID231 and CJ1W-OD231 respectively, and the modules are connected by cables. The analog input module can directly collect 0~10V / 4~20MA standard signal, and the analog output module converts the optimized output value of the central controller into 0~10V / 4~20MA standard signal and sends it to the actuator to start the motor.

[0029] The actuator adopts the NX series inverter of Finland VACON. ...

Abstract

This invention is an energy saving fuzzy control device and its control method of a new type environmental friendly central air conditioner system. The control device includes power supply element, data collecting element, central controller, data display processor, communicating module and host computer. This invention uses modern fuzzy control technique. Fuzzy control rule is determined according to long time experiences and skills. Professional energy saving knowledge and human thinking process are added into the said fuzzy control rule. The collected data undertake fuzzy process and fuzzy reasoning. The reasoned fuzzy control is changed into actual control value in order to fulfill the optimal control of whole central air conditioner system.

Description

technical field [0001] The invention relates to a fuzzy control device and a control method, in particular to a novel green central air-conditioning system energy-saving fuzzy control device and control method. technical background [0002] Energy is the material basis necessary for human survival and social development. In the 21st century, energy shortage has become a worldwide problem for the economic development of all countries. With the continuous development of the economy and the continuous improvement of people's living standards, the requirements for the comfort of air conditioners and indoor air quality are also getting higher and higher. At present, the energy consumption of buildings accounts for about 1 / 3 of the national energy consumption, and about 50%-60% of the annual energy consumption of public buildings (especially large shopping malls, high-end hotels, high-end office buildings, etc.) Consumed in air conditioning refrigeration and heating systems, in o...
