Description
Technical field
This utility model relates to airconditioning control field, particularly relates to a kind of adaptive air quantity variable air conditioner wind pushing temperature controller.
Background technology
In Central air-conditioning unit, the critical component that pressure fan carries as air-flow, it act as enough air-flows are transported to each end equipment, the transporting cold-air when summer, and winter, heat air delivery, maintained the temperature of residential area in acceptable scope.Owing to the air output of blower fan is according to selected under the design wind pushing temperature under conditions of maximum cold load in summer, namely in view of extreme conditions, but in physical device runs, unit equipment runs in the case of being often in the load of relatively low cold heat, thus the power consumption of unit may often be such that unnecessary and waste.
In typical air quantity variable air conditioner blower fan control system, wind pushing temperature is relatively fixed, such as, keep 13 C when of summer, and winter 18.3, C(U.S.A such as added at the area) or C in summer 16 C(or higher in winter 18.3, China).Arrange in the case of needing refrigeration or heat supply due to setting value for whole building, like this can not only need under the weather conditions freezing but also needing heat supply, to cause unnecessary end reheating, thus cause the waste of the energy.It addition, setting value arranges the improper air quantity that will also result in the unnecessary offer excess of blower fan, thus cause the unnecessary waste of blower fan energy.
In modified hydrothermal process, have according to average zone temperature, have linearly resets setting value according to outdoor temperature.Both algorithms improve end heat more to a certain extent.But also lack certain motility, it is impossible to reach optimum energy-saving effect simultaneously.
Utility model content
Technical problem to be solved in the utility model is that the deficiency existed for above-mentioned prior art provides a kind of and can realize to the optimum control of wind pushing temperature, to reach the adaptive air quantity variable air conditioner wind pushing temperature controller of energy-conservation purpose.
The technical scheme that this utility model is used is: a kind of adaptive air quantity variable air conditioner wind pushing temperature controller, it is characterised in that: include cold valves, hot water valve, wind pushing temperature sensor, outdoor temperature sensor, setting value processor, switch controller, converter；Described wind pushing temperature sensor is all connected with setting value processor with outdoor temperature sensor, and described switch controller includes PID controller and opening controller；The signal input part of described PID controller is connected with setting value processor and wind pushing temperature sensor, signal output part is connected with opening controller, described opening controller is connected with cold valves and hot water valve, and for controlling both apertures, described converter is connected with blower fan and setting value processor.
By technique scheme, described wind pushing temperature sensor is arranged on blower fan air outlet.
By technique scheme, described outdoor temperature sensor, wind pushing temperature sensor, converter, the output electric current of opening controller are 4-20mA current signal.
By technique scheme, it is the difference signal of duty setting signal and wind pushing temperature sensor temperature signal between described setting value processor and PID controller.
When pressure fan is opened, outdoor temperature sensor signal is delivered on setting value processor, setting value processor sets wind pushing temperature setting value initial value according to institute's derived signals, the difference of controlled volume (wind pushing temperature that wind pushing temperature sensor is measured) and setting value is after PID controller, send opening degree command and controlled the output of cold valves/hot water valve by opening controller, thus regulating the aperture of cold water/hot water valve.Hereafter, often crossing a spacer segment (just setting 5 minutes, adjustable), setting value processor carries out calculating replacement wind pushing temperature setting value according to wind pushing temperature sensor, outdoor temperature sensor and converter institute feedback signal.To reach the control of optimal wind pushing temperature.
Have the beneficial effect that this utility model is different from conventional wind pushing temperature setting value and immobilizes or change but numerical value arranges inaccurate acquired by this utility model, by fan speed and time interval parameter, optimal wind pushing temperature can be predicted accurately, thus avoid air-supply temperature to be set to Tai Gao or the lowest thus cause the generation of unnecessary reheating (simultaneously heating refrigeration).Meanwhile, rational wind pushing temperature, blower fan high-speed cruising at low load can be avoided, or refrigeration unit is run under poor efficiency, thus cause energy waste.Energy-conservation more than 10% can be continued on the basis of traditional frequency conversion control.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, present embodiments provide a kind of adaptive air quantity variable air conditioner wind pushing temperature controller, including cold valves 1, hot water valve 2, wind pushing temperature sensor 5, outdoor temperature sensor 6, setting value processor 7, switch controller, converter 3；Described wind pushing temperature sensor 5 is all connected with setting value processor 7 with outdoor temperature sensor 6, and described switch controller includes PID controller 8 and opening controller 9；The signal input part of described PID controller 8 is connected with setting value processor 7 and wind pushing temperature sensor 5, signal output part is connected with opening controller 9, described opening controller 9 is connected with cold valves 1 and hot water valve 2, for controlling both apertures, described converter 3 is connected with blower fan 4 and setting value processor 7.Wherein, described wind pushing temperature sensor 5 is arranged on blower fan air outlet, and described outdoor temperature sensing 6 is disposed in the outdoor at sunshade.Described outdoor temperature sensor 6, wind pushing temperature sensor 5, converter 3, the output electric current of opening controller 9 are 4-20mA current signal.It it is the difference signal of duty setting signal and controlled volume (wind pushing temperature sensor temperature signal) between described setting value processor 7 and PID controller 8.
When blower fan 4 is opened, outdoor temperature sensor 6 signal is delivered on setting value processor 7, setting value processor 7 sets wind pushing temperature setting value initial value according to institute's derived signals, the difference of controlled volume (wind pushing temperature that wind pushing temperature sensor is measured) and setting value is after PID controller 8, send opening degree command and controlled the output of cold valves 1/ hot water valve 2 by opening controller 9, thus regulating the aperture of cold water/hot water valve.Hereafter, often crossing a spacer segment (just setting 5 minutes, adjustable), setting value processor 7 carries out calculating replacement wind pushing temperature setting value according to the signal that wind pushing temperature sensor 5, outdoor temperature sensor 6 and converter 3 are fed back, to reach the control of optimal wind pushing temperature.
This utility model is different from conventional wind pushing temperature setting value and immobilizes or change but numerical value arranges inaccurate.By fan speed and time interval parameter so that optimal wind pushing temperature can be predicted accurately, thus avoid air-supply temperature to be set to Tai Gao or the lowest thus cause the generation of unnecessary reheating (simultaneously heating refrigeration).Meanwhile, rational wind pushing temperature, blower fan high-speed cruising at low load can be avoided, or refrigeration unit is run under poor efficiency, thus cause energy waste, energy-conservation more than 10% can be continued on the basis of traditional frequency conversion control.
