Description
Technical field
The utility model relates to the utility model and relates to central air conditioner system, relates in particular to a kind of fan coil system end equipment and control system of water pump.
Background technology
At present, central air conditioner system has obtained application more and more widely in various building constructions such as dwelling house, commercial office building, hotel.The end equipment of air-conditioning system directly affects the control effect to indoor environment, has also directly reflected the cold and hot amount of system.Form according to air-conditioning system is different; The end of air-conditioning system also has various ways; Situation with regard to the present air-conditioning system of China; Primary air fan-coil system is to use the widest air-conditioning system in domestic all kinds of offices at present and the hotel architecture, in the central air conditioner system of China is used in occupation of main status.The Energy Saving Control of research fan coil system has great significance.
Fan coil cooling unit belongs to half central air-conditioning system, also is a kind of principal mode of air-water air-conditioning system.Fan coil units mainly is made up of blower fan, coil pipe, air cleaner, adjusting device and casing.Fan coil is directly installed in the air-conditioned room, and flow through cold water or hot water and the coil pipe air generation heat exchange outward of flowing through in the coil pipe reach the purpose of air conditioning.Easy for installation, the flexible arrangement of fan coil, but independent regulation room temperature and other rooms are not exerted an influence basically, the adjusting needs when being prone to adapt to the fluctuation of building internal loading are convenient to building and are increased the expansion air-conditioning system; The fan coil type is little, and it is few to take space, practices thrift the building floor height, and owing to there is not airduct, fire and smoke exhaust and noise transfer problem all solve than being easier to; As far as water system, because the drag losses of fan coil is bigger, thereby water system is difficult for imbalance in addition.
The control of fan coil is exactly in order to regulate the cooling amount of coil pipe.Can know that from the principle of fan coil the cold adjusting can adopt air quantity adjusting, the water yield to regulate and water temperature is regulated, wherein water temperature is regulated the concentrated regulating measure of genus, mainly according to load condition whole system is regulated; It mainly is manual third gear fan speed regulation that air quantity is regulated, temperature control blower fan three-step timing; Water yield control mainly is the control of temperature control electromagnetic break-make.At present, control mainly is through accomplishing with the temperature controller of the corresponding setting of each fan coil for the end of fan coil, and automaticity is higher mainly contains temperature control force 3 wind machine speed governing type and the speed governing of force 3 wind machine and add electronic flow control valve and control temperature controller.Temperature control force 3 wind machine mode of speed regulation will be through being arranged on the real time temperature that temperature sensor in the room records the room, according to the temperature value of setting, and the manner of execution that judgement should be taked, the too high corresponding reduction gear of temperature, temperature is crossed the low gear of then heightening.Because the simplicity of this regulative mode self; Have some defectives: because the thermal inertia of air-conditioned room is very big; Water coil in the fan coil also has bigger thermal inertia; Therefore so simple control just causes bigger fluctuations in indoor temperature, especially under the situation of underload, very easily produces imbalance.The reason that this phenomenon occurs relies on indoor temperature to judge that the method for regulating direction does not have " foresight " merely with regard to being; Only controlled the direction of regulating, but accurately do not held, because the hysteresis quality that air-conditioning system is regulated for " amount " of regulating; The corresponding action of regulating, sensor just takes place after detecting the tolerance interval that temperature exceeds design temperature; But this moment, indoor temperature can not return in the tolerance interval after action takes place immediately, if during this period, temperature controller does not in time change regulates rule; Still according to former regular further adjusting; Then be easy to make controlled plant generation overshoot, the phenomenon of indoor temperature recurrent fluctuations so just occurs, influence indoor comfort level.
Above-mentioned temperature controller is to disperse independent control formula temperature controller, also has the following shortcoming of this type of temperature controller simultaneously:
1, owing to do not have communication between each temperature controller; Work alone separately, do not become system, can't unified Analysis, weigh each terminal working condition; Thereby low-temperature receiver and distributing system can't regulate according to the load condition of end accurately, and some complicated Optimal Control Strategy can't be implemented.
2, because each temperature controller decentralised control, the administration of energy conservation that can't concentrate occurs easily that the user of service leaves and the fan coil end is still opened the situation about wasting energy of operation.
