Embodiment
Referring to Fig. 2, machine room energy management system structural representation of the present invention, this system comprises upper energy management computing machine 4, ethernet line 13, protocol converter 14, computer lab management device 6, RS485 bus 15, central air conditioner main machine group 16, thermometer 17, cold and hot scale 18, watt-hour meter 19, fuel meter 20, and this fuel meter 20 specifically is used for combustion gas, fuel oil air-conditioner host and water pump 21, cooling tower 22.
Computer lab management device 6 is used to measure the cold and hot scale 18 that air-conditioner host is exerted oneself by the collection of RS485 bus.Cold and hot scale 18 goes out real-time refrigerating capacity or heating capacity and both aggregate-values of air-conditioner host into and out of temperature and air conditioner water flow rate calculation by the air conditioner water of measuring air-conditioner host, and convert they and air conditioner water flow (200m2/h) and import/export temperature (12oC/7 ℃) to 4~20mA signal and issue computer lab management device 6, computer lab management device 6 is used to measure watt-hour meter 19 and the fuel meter 20 of gas consumption and the watt-hour meter of metering water pump and cooling tower power consumption of air-conditioner host power consumption by the collection of RS485 bus.These ammeters and fuel meter are converted to real-time current, voltage, electric power, fuel consumption and accumulative total power consumption and air consumption 4~20mA signal and issue computer lab management device 6.
In addition, computer lab management device 6 also is connected to outdoor temperature sensor, chilled water import and export temperature sensor, directly temperature signal is converted to digital signal.
Computer lab management device 6 is according to the energy input of the data in real time computation host that collects, the refrigerating capacity and the Energy Efficiency Ratio (being the COP value) of output.Send then when it is lower than Energy Efficiency Ratio from the energy management computer settings that efficiency is low reports to the police, and to provide preliminary diagnosis be the air-conditioner host problem, or the water system problem.Computer lab management device 6 according to air conditioner water import and export temperature calculate in real time buildings must refrigerating capacity, and determine the platform number of air-conditioner host, water pump, cooling tower operation in view of the above, to realize Energy Saving Control.For example, when air conditioner water import and export temperature less than 3 ℃, when outlet temperature was lower than 5 ℃, it is specified 60% that load is lower than, then computer lab management device 6 sends the instruction that stops 1 operation to central air conditioner unit 16.
Computer lab management device 6 is compared the water pump of the air-conditioner water system of gathering from ammeter and the power consumption of cooling blower with the air-conditioner host refrigerating capacity.When surpassing setting value on the energy management computing machine, sends ratio warnings that exceed standard of water pump or cooling blower energy consumption, and the flow of corresponding reduction water pump and cooling blower frequency, water system energy consumption and air-conditioner host refrigerating capacity are complementary, elimination low load with strong power phenomenon.
When outdoor environment temperature changed, computer lab management device 6 is revised the air-conditioner host leaving water temperature automatically made the main frame realization energy-conservation, and the water pump of also corresponding adjusting water system and the rotating speed of cooling blower are realized the energy-conservation of water system simultaneously.For example, during refrigeration, when environment temperature descends 2 ℃ the time, computer lab management device 6 sends to central air conditioner main machine the air conditioner water outlet temperature is heightened 1 ℃.(whenever heightening 1 ℃ can save energy about 6%).
Upper energy management computing machine 4 through protocol converter 14, is converted to ICP/IP protocol the communication mode of the RS485 that is connected with computer lab management device 6 by ethernet line 13.It is to utilize the existing LAN (Local Area Network) of building system that the purpose of Ethernet is adopted in the upper strata networking, does not need to carry out in addition the RS485 wiring, reduces cost, and reduces quantities.
Upper energy management computing machine 4 through ethernet line 13, protocol converter 14 gather operating mode in the computer lab management devices 6 and energy consumption data (as temperature, flow, power consumption, gas consumption, water consumption, plant efficiency) carry out statistical study, and set up be easy to inquire about can source database and friendly man-machine interface, with help people better, energy management more easily.
On upper energy management computing machine 4, energy management software is housed, the energy consumption parameter (as peak power, maximum current, average power consumption, on average consume gas, equipment av eff etc.) of air conditioner water leaving water temperature, cooling tower leaving water temperature, water pump frequency and each energy consumption equipment of central air conditioner main machine can be set.In case equipment energy consumption exceeds standard or equipment breaks down (data are uploaded to upper energy management computing machine 4 by computer lab management device 6), then on upper energy management computing machine 4, report to the police, and the display alarm reason.
Energy management software on the upper energy management computing machine 4, electricity price (can be provided with by spike, peak, flat section and low ebb segmentation), gas price and water price can be set, and automatic computing equipment when per, every day, weekly, every month and the annual used electricity charge, gas expense, water rate.In case finding the energy expenditure of certain equipment period than the mean heights 20% of preceding 3 periods (environment temperature, air conditioner load change be no more than 8%), then sends the energy and uses abnormal alarm.
If but energy expenditure and environment temperature and the proportional rising of air conditioner load are not then reported to the police.Upper energy management computing machine 4 is provided with database, is used to deposit from computer lab management device 6 gather the equipment working condition data of coming up, energy consumption data, alert data, the parameter of setting, the expense that the energy uses, so that data are carried out statistical study and historical query.
The energy resource consumption data of the actual measurement of upper energy management computing machine 4 embedded a large amount of all kinds of buildings (as star hotel, office building, station, airport, market etc.) (energy expenditure that consumes as the air-conditioning of the Air-conditioner design load of every square meter, the air-conditioning actual load of every square meter, every square meter etc.), can provide reference for the energy management of all kinds of buildings, as determining etc. of the control target of the determining of the desired value of energy control, energy expenditure.
