The air-conditioner set is earth source heat pump unit and unit quantity is greater than 1, and water pump is divided into cooling water pump, chilled water
Pump, and quantity is consistent with air-conditioner set quantity.
Compared with prior art, the utility model has the beneficial effects that
The utility model air-conditioning system controls air-conditioning equipment using the fuzzy controller of existing maturation, this is practical
It is novel that now air-conditioned improvement is to be equipped with Temperature Humidity Sensor in outdoor ventilation, it is passed according to outdoor temperature humidity
The temperature and humidity that sensor obtains, obtains the end load under this environment, final to determine that obtaining earth source heat pump unit open
Number of units, and open corresponding water pump and blower.The unlatching quantity of the utility model air-conditioning system earth source heat pump unit is basis
What the temperature and humidity that outdoor temperature humidity sensor obtains was adjusted, rather than be all turned on, so the fortune of equipment can be reduced
Row, greatly reduces energy consumption and operating cost.
By being mounted on for the sensor on water return pipeline, 4- is converted by flow, for pressure of return water and supply and return water temperature
The standard signal of 20mA is sent in fuzzy controller, and fuzzy controller is blurred according to collected data, will be obscured
Change data to be sent in fuzzy controller, fuzzy controller carries out the aim parameter of current collected semaphore and default
Compare, and computation of table lookup obtains control amount, then gives frequency converter by control amount defuzzification, and by digital analog converter, by becoming
The revolving speed of frequency device control motor carrys out the water supply flow of regulating system, and the closed-loop control that fuzzy controller is formed makes system for return water temperature
Difference is constant in setting value.By the sensor being mounted on air hose, the standard signal that return air temperature is converted to 4-20mA is sent
Enter into fuzzy controller, data are by blurring, and fuzzy controller is by the mesh of current collected semaphore and default
Scalar is compared, and computation of table lookup obtains control amount, then gives frequency conversion by control amount defuzzification, and by digital analog converter
Device finally adjusts room temperature by the revolving speed of Frequency Converter Control blower motor come regulating system volume of air supply, and fuzzy controller is formed
Closed-loop control make room temperature is constant to reset value.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, central air conditioner system of the utility model based on fuzzy controller, including fuzzy controller, center
