Embodiment
Illustrate the preferred embodiments of the present invention in conjunction with accompanying drawing.
Fig. 1 is first preferred embodiment that energy saving air-conditioning cold of the present invention doubts system.Include as illustrated, the energy saving air-conditioning cold doubts system：Conditioner 33, the conditioner 33 includes heat exchanger 331 and is placed in the blower fan 332 of the side of heat exchanger 331, and heat exchanger 331 is provided with water inlet 311 and delivery port 312；The refrigerator 11 of chilled water is provided to heat exchanger 331, refrigerator 11 is provided with chilled water import 112 and chilled water outlet 111, chilled water inlet pipe 606 is connected between the delivery port 312 of chilled water import 112 and heat exchanger 331, chilled water outlet pipe 607 is connected between chilled water outlet 111 and the water inlet 311 of heat exchanger 331；Chilled water temperature sensor 604 and 605, it is attached separately on chilled water inlet pipe 606 and chilled water outlet pipe 607；Chilled water pump 601, it is in chilled water outlet pipe 607；Connect the cooling device 22 of refrigerator 11；Three Temperature Humidity Sensors 81；And controller 44.The controller 44 is a programmable controller, is electrically connected conditioner 33, refrigerator 11, chilled water temperature sensor 604 and 605, chilled water pump 601, cooling device 22 and Temperature Humidity Sensor 81.
As shown in figure 1, as first preferred embodiment of the present invention, conditioner 33 is that fan coil unit, i.e. heat exchanger 331 are a coil pipe, and air can flow through between pipe, and chilled water then flows through in pipe；Blower fan 332 is centrifugal blower, and it is located at the side of coil pipe 331.Controller 44 controls open and close and the rotating speed of blower fan 332.Fan coil unit 33 is arranged in the space 800 for needing to carry out air adjustment.Fan coil unit 33 is connected with the ajutage 82 and backwind tube 83 being distributed in space 800 respectively, and the air that need to be handled is blowed to coil pipe 331 by blower fan 332 by backwind tube 83, and air flows through coil pipe 331, and direction is as shown in arrow 301 in figure.Air generates heat exchange, i.e. air by the heat transfer of itself to chilled water, the temperature of such air will be reduced when flowing through coil pipe 331 with the chilled water in pipe.If the moisture in air is excessive, part moisture is precipitated, so that the humidity of air is reduced, so as to finally realize while adjusting the purpose of air themperature and humidity.Air after cooling is sent in space 800 by ajutage 82, and air is constantly circulated by fan coil unit 33 like this.Chilled water pump 601 can ensure that chilled water is circulated between fan coil unit 33 and refrigerator 11, and controller 44 controls open and close and the rotating speed of chilled water pump 601.
Refrigerator 11 is the water-cooled Screw chiller cooled down with water, which is provided with cooling water inlet 114 and coolant outlet 113, and controller 44 controls its open and close and the output of cold.Cooling device 22 is cooling tower, is that water-cooled Screw chiller 11 provides cooling.Controller 44 controls open and close and the rotating speed of the axial flow blower 221 on cooling tower 22.Cooling water inlet 114 and coolant outlet 113 are linked together by cooling water inlet pipe 502 and cooling water outlet tube 503 with cooling tower 22, and cooling water pump 501 is housed on cooling water outlet tube 503, wherein cooling water pump 501 is also controlled by controller 44, and such cooling water can just be circulated between water-cooled Screw chiller 11 and cooling tower 22.
Chilled water inlet pipe 606 is equipped with a triple valve 603 on one end of chilled water import 112, and chilled water temperature sensor 604 is on the valve, and such chilled water temperature sensor 604 just can more accurately measure temperature of the chilled water at chilled water import 112；Similarly, chilled water outlet pipe 607 is also equipped with a triple valve 602 on one end of chilled water outlet 111, chilled water temperature sensor 605 is on the valve, and such chilled water temperature sensor 605 just can more accurately measure temperature of the chilled water at chilled water outlet 111.Adjusted in addition, three Temperature Humidity Sensors 81 are evenly distributed in space 800, to measure the aerial temperature and humidity of diverse location.Then there be the pre-set air temperature value and humidity value adjusted required for space 800 in controller 44, and air temperature value and humidity value are adjustable.So, controller 44 just can be according to the temperature value and humidity value measured by Temperature Humidity Sensor 81, it is determined that by the thermic load and humidity load of tune air and the cold of required offer, and then adjusts the rotating speed of blower fan 332；The freezing temperature of controller 44 again according to measured by chilled water temperature senses 604 and 605, it is determined that the freezing water entrance temperature difference, then controller 44 outputs signal to frequency converter 608 according to temperature difference situation, frequency converter 608 then adjusts the rotating speed of chilled water pump 601, the cold output of final adjustment water-cooled Screw chiller 11, so that the present invention can be adjusted as needed is had the effect saved by tune aerial temperature and humidity again.
Fig. 2 is second preferred embodiment of the invention.As illustrated, controller 44 controls the rotating speed of blower fan 332, chilled water pump 601 and cooling water pump 501 by fan frequency converter 333, chilled water pump frequency converter 608 and cooling water pump frequency converter 504 respectively.On cooling water inlet pipe 502 and triple valve 507 and 506 is respectively provided with cooling water outlet tube 503, two valves are respectively close at cooling water inlet 114 and at coolant outlet 113.Cooling-water temperature sensor 508 and 509 is separately mounted on triple valve 507 and 506, for measuring the temperature difference of the cooling water at cooling water outlet and inlet.Cooling-water temperature sensor 508 and 509 respectively passes to temperature signal in controller 44, and controller 44 outputs signal to frequency converter 504 according to temperature difference situation, and frequency converter 504 adjusts the rotating speed of cooling water pump 501 according to the temperature difference.I.e. the frequency of frequency converter 504 changes with the change of the temperature difference at cooling water outlet and inlet, specifically, and when temperature difference change is small, the frequency that frequency converter 504 is exported is increased by, and is conversely then reduced.The rotating speed of cooling water pump 501 is then accelerated with the increase of the frequency of frequency converter 504, reduce and it is slack-off.In addition, controller 44 sends the temperature signal measured by Temperature Humidity Sensor 81 to fan frequency converter 333, fan frequency converter adjusts the rotating speed of blower fan 332 according to this temperature signal.The energy-saving effect of the present invention is thus can further improve.
As shown in figure 3, as the 3rd embodiment of the present invention, energy saving air-conditioning cold, which doubts system, also includes a remote controllers 45.Remote controllers 45 are connected with controller 44, and by controller 44 so control fan coil unit 33, refrigerator 11, cooling tower 22, chilled water pump 601 and cooling water pump 501 open and close and operating.The personnel control energy saving air-conditioning cold that is so convenient to operation doubts system.
Fig. 4 is the 4th preferred embodiment of the present invention, is being adjusted the outside in space 800 to be additionally provided with an Atmosphere temp.and RH sensor 85, the Temperature Humidity Sensor is connected with controller 44.There are the maximum temperature and maximum relative humidity of air set in advance in controller 44, when the temperature or humidity of air exceed value set in advance, regardless of the humiture for being adjusted space, controller 44 can all start energy saving air-conditioning cold and doubt system, to prevent the humidity of external environment condition too big, influence to be adjusted the operating of equipment in space.
Above disclosed is only presently preferred embodiments of the present invention, can not limit the interest field of the present invention, therefore the equivalent variations made according to scope of the present invention patent with this certainly, still belongs to the scope that the present invention is covered.
