Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, clearly, referring to the accompanying drawing embodiment that develops simultaneously, this utility model is described in further detail.

Referring to Fig. 1 and Fig. 2, a kind of portable intelligent Energy Efficiency Ratio of the present embodiment measures system, and mainly by inserted electromagnet flow meter, intelligent portable energy meter, data converting transmission module, customer center server or cloud center-----, namely computer, on-the-spot portable display terminal etc. form.Inserted electromagnet flow 1 and inserted electromagnet flow 2 are respectively installed on feed pipe and the return pipe in Air Conditioning Facilities system superintendent road, inserted electromagnet flow meter is as liquid phase related parameter data acquisition and storage device, it is thus achieved that feed pipe pipeline and the temperature of return pipe pipeline, flow, flow velocity parameter；Intelligent portable energy meter is arranged on the total input-wire end of correspondence system, as associated parameter data collection and the storage device of electric power, it would be desirable to the system of measurement is monitored measuring as entirety, measures the parameter of the electric current of system, voltage, power.

Work process is as shown in Figure 2, inserted electromagnet flow meter 1 and inserted electromagnet flow 2 are first respectively installed on feed pipe and the return pipe of main pipeline, according to different calibers before measuring system operation by Energy Efficiency Ratio, supporting altitude mixture control sleeve pipe can be selected, arrive adaptive requirement.Securing member can ensure within a period of time that measurement apparatus is fixed on pipeline and water-tight.Energy meter is arranged on the total input-wire end of correspondence system simultaneously.Energy meter is clipped on the equipment inlet wire needing to measure, access power supply and Wireless transceiver module.

Inserting-type flowmeter is as liquid phase related parameter data acquisition and storage device, it is possible to according to Faraday law of electromagnetic induction: when conducting liquid makes cutting magnetic line movement in magnetic field, produces induced potential in conductor, and its induced potential E is:

E=KBVD

In formula: K-instrument constant B-magnetic induction V-measures the mean flow rate D-in pipeline section and measures the internal diameter of pipeline section.

When measuring flow, conductive liquid flows through the magnetic field being perpendicular to flow direction with speed V, the flowing of conductive liquid induces the voltage being directly proportional to mean flow rate, its induced voltage signal is picked by two or more than two electrodes directly contacted with liquid, and by the intelligent processing method of analog signal converter, it is then converted into standard signal 4～20mA and 0-1khz output.The parameter of correspondence is changed into by analog signal converter.Effusion meter can be passed through in native system obtain: temperature, flow (needing input caliber size), flow velocity simultaneously.It is sent to wireless transport module by digital serial port RS232/RS485 simultaneously, by ICP/IP protocol, data is sent to customer center server or cloud central record by GPRS form and is saved in data field, carrying out data storage.

By the synchronicity of network time, it is possible to overlap inserted electromagnet flow meter by two Tong Bu with the sample start times of energy meter.Sampling period default setting is 5 seconds, it is not necessary to operate by starting simultaneously, and all data are all continuously monitored record after entering customer center server, and user can carry out checking, analyzing for the data in any instant or any time period.The data that time for just start, system is unstable, it is possible to reset and reset, to guarantee that data are authentic and valid.After electromagnetic flowmeter parameter is sent to customer center server by GPRS form, data cog region identifies automatically for different temperature, two temperature t1, t2 of temperature sensor are below 15 DEG C, system mode is cooling condition, the temperature that now numerical value is low is defaulted as t2, on position is water main, and another one temperature is then defaulted as t1, and on position is backwater main.If the two of temperature sensor temperature t1, t2 are more than 30 DEG C, system mode is heating condition, and the temperature that now numerical value is high is defaulted as t2, and on position is water main, and another one temperature is then defaulted as t1, and on position is backwater main.

Air conditioning system data corresponding in data field, by energy consumption computing module, are carried out computing by customer center server (computer), it is possible to obtain refrigerating capacity (or refrigeration heat) Qn, also store data into data field simultaneously.

$Qn\left(i\right)=\underset{i=1}{\overset{k}{\Σ}}Qn\left(i\right)*C*qv*(t1-t2)*\mathrm{\ρ}$

The unit net refrigerating capacity (heating capacity) that Qn (i) is this operational factor sampling period, kW；Qn is accumulative handpiece Water Chilling Units net refrigerating capacity, kW；C is that specific heat of water holds, 4.2 (kilojoule per kilogram. DEG C, kJ/kg DEG C), ρ is the density of water, (kilograms per cubic meter, kg/m3).In formula, (t1-t2) is the chilled water in this operational factor sampling period for, backwater temperature difference, and qv is current time cooling pipe network chilled water volume flow (cube m/h, m3/h).

By energy consumption computing module, power data corresponding in data field is carried out computing, it is possible to power P t corresponding under (or refrigeration heat) operating mode of being freezed, also store data into data field simultaneously.

$Pt=\underset{i=1}{\overset{k}{\Σ}}\mathrm{Pr}\left(i\right)$

Refrigeration work consumption Pr (i) in sampling period (kilowatt, kW), refrigeration work consumption Pt (kilowatt, kW).

According to operational data refrigerating capacity (or refrigeration heat) Qn, and power P t, it is possible to calculate the trapped energy theory (cooling condition) of system, COP (heating condition).

$EER\left(COP\right)=\frac{Qn}{Pt}$

And instantaneous Energy Efficiency Ratio

Owing to analog signal converter has communication serial ports, transfer data to customer center server background by Wireless transceiver module, it is achieved the functions such as historical data reading, inquiry, preservation, computing, printing.After system run all right, data are constantly uploaded onto the server intelligent platform, and server can obtain the Energy Efficiency Ratio of real-time Energy Efficiency Ratio and any time period through computing.Can automatically identifying that union goes out Energy Efficiency Ratio by software, and compare with the reference value in data base, if not in reasonable value range, system will remind surveyor, and judge problem and the solution be correlated with according to the value of parameters.Data are also fed back to on-the-spot portable display terminal by GPRS form by customer center server in real time, in order to Field Force carries out the work.System run all right, after drawing stabilization result, Energy Efficiency Ratio measures and can terminate.

Should be understood that; the application of this patent is not limited to above-mentioned citing, for those of ordinary skills, it is possible to is improved according to the above description or converts; all these improve and convert the protection domain that all should belong to this patent claims, repeat no more here.
