Abstract
The utility model mainly discloses a variable-frequency energy saving device for a water circulating pump of a centralized control system of a central air conditioner, which comprises a host machine, a plurality of ends, a plurality of end controllers and a centralized control system of a central air conditioner, wherein water supply pipes and water return pipes are connected between the host machine and the ends. The flow of the refrigerant water of the central air conditioner is driven by refrigerating pumps which are arranged on the water return pipes and are provided with frequency converters, and the signal outputs of the end controllers controlling the working of the ends are connected to the centralized control system of the central air conditioner; and meanwhile, a central controller of the centralized control system of the central air conditioner is connected with the control ends of the frequency converters. According to the variable-frequency energy saving device for the water circulating pump of the centralized control system of the central air conditioner, the running state of the water circulating pump of the central air conditioner is changed according to the actual use conditions of the ends of the air conditioner, and the optimized energy-saving control is realized.
Description
Technical field
The utility model relates to the air conditioner energy saving technical field, is applicable to that particularly the energy-saving central air-conditioning centralized control system water circulating pump frequency converting and energy saving device in large-scale places such as hospital, market, school is relevant.
Background technology
Central air-conditioning is an indispensable facility in the life now, some large-scale public places particularly, as hospital, market, school, station or the like, central air-conditioning is compared with indoor common air-conditioning, main advantage can indoor temperature remain in the desired scope exactly, can make room air fresh again, help healthy.
But because central air-conditioning all is large-scale concentrated controling management system, power is big, and power consumption is big, and the payment electricity charge become user's a huge spending.Such as hospital, air-conditioning all can not be left in most places, and operating room, ward, with regard to clinic etc. all are to keep suitable temperature basically throughout the year, and according to budget, the central air-conditioning energy consumption accounts for about 60% of whole building energy consumption, and energy consumption is very huge.
Owing to flow at indoor occupant, various factors such as temperature fluctuation, the central air conditioner system refrigerating capacity has tangible workload demand dynamic change, and the lift (power) of water pump all has sizable allowance when design.So it is necessary and the Remarkable Energy Saving effective measures that whole central air conditioner system is carried out reducing energy consumption.
So the inventor is exactly under this industry technology environment, develop a cover central air-conditioning centralized control system water circulating pump frequency converting and energy saving device, this case produces thus.
Summary of the invention
The purpose of this utility model is to provide a kind of central air-conditioning centralized control system water circulating pump frequency converting and energy saving device, changes water circulating pump running status in the central air-conditioning centralized control system according to actual air-conditioning applied load situation, realizes the optimization Energy Saving Control.
What to achieve these goals, the utility model adopted is that technical scheme is:
Central air-conditioning centralized control system water circulating pump frequency converting and energy saving device comprises main frame, some ends and terminal controller, central air-conditioning centralized control system, is connected with feed pipe and return pipe between main frame and the end; The refrigerating water pump that the band frequency converter is housed on return pipe drives circulating of central air-conditioning chilled water, the terminal controller signal output of the terminal work of control is connected to the central air-conditioning centralized control system, and the central controller of central air-conditioning centralized control system connects the control end of frequency converter simultaneously.
Described refrigerating water pump is parallel with standby refrigerating water pump, and each all has frequency converter.
After adopting such scheme, the utility model is by detecting the situation that terminal air-conditioning uses, there is terminal controller that signal is sent to the central air-conditioning centralized control system then, send in real time dynamic control instruction by the central air-conditioning centralized control system and give frequency converter, power by the Frequency Converter Control refrigerating water pump, make refrigerating water pump under actual environment for use,, reduce the use energy consumption of central air-conditioning greatly with optimized state work.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the schematic diagram that is electrically connected of the utility model preferred embodiment.
The specific embodiment
In conjunction with the accompanying drawings, the utility model is described in further details.
Central air-conditioning centralized control system water circulating pump frequency converting and energy saving device mainly comprises main frame 1, some terminal 2, terminal controllers 3, central air-conditioning centralized control system 4.
On refrigerating water pump 7, be connected with frequency converter 9, each end 2 is furnished with a terminal controller 3, terminal controller 3 is gathered the electronic equipment of the duty of end 2, the signal that collects is sent in the central air-conditioning centralized control system 4, receive the control instruction of central air-conditioning centralized control system 4 simultaneously, and the duty of control terminal 2.
Central air-conditioning centralized control system 4 adopts computer as data processing centre, is the Core server in the central air-conditioning centralized control system, has been comparatively ripe device in electron trade, does not do here and gives unnecessary details.Central air-conditioning centralized control system 4 scans terminal controller 3 at regular intervals, gathers the duty of all ends 2, transfers the signal to the then in the central air-conditioning centralized control system 4.Central air-conditioning centralized control system 4 draws control signal corresponding with the signal processing that converts, and is sent in the frequency converter 9 by the central controller in the central air-conditioning centralized control system 4.Frequency converter 9 is changed by frequency conversion, refrigerating water pump 7 is adjusted on the suitable power rating moves.So frequency converter 9 does not need to be in work under the full load condition, has greatly reduced the work energy consumption, can save the energy about 50% in 1 year substantially always.
