Abstract

An integrated water chiller performance testing instrument comprises two outer-connected flow probes, four temperature probes, a current probe, a voltage probe, and a box body which is internally provided with a heat energy calculation IC board, an electric power calculation IC board and a programmable logical controller. The front surface of the box body is provided with a human-machine interface panel which can display various measured values and functional operations. The back surface of the box body is provided with a socket back panel which can be connected with various probe extension lines for transmitting the measured values such as flow, temperature, current and voltage to the programmable logical controller through a communication interface. After being edited and integrated by the software, the measured values are transmitted to a computer for analyzing and monitoring. Therefore, the water chiller performance testing operation is simplified for saving cost, manpower and labor hour.

Description

Integral type frozen water function force tester device

Technical field

The utility model relates to a kind of frozen water function force tester device, refers in particular to a kind of portability integral type frozen water function power tester that aims at test frozen water machine integration capability.

Background technology

The frozen water machine is the refrigerating machine of the central air conditioner system indispensability of buildings such as office block, department stores, Electronics Factory and hospital, because of the power consumption of frozen water machine accounts for more than 50% of the total power consumption of central air conditioner system, need in factory, to carry out the integration capability test of frozen water machine before so not only dispatch from the factory, contain the test of evaporator refrigeration heat energy, condenser heat radiation heat energy and compressor electric power, to determine that its power consumption meets national standard, and also needed per 2～3 years carry out the integration capability test of a frozen water machine at the use scene, cause power wastage to check its ability whether to fail.

As shown in Figure 1, frozen water machine 10 is by evaporator 11, condenser 12, compressor 13 assemblies such as grade constitute, and external frozen water pipe 14 and cooling water pipe 15, through looking into, there is no the instrumentation that test frozen water machine integration capability is used in the prior art, therefore, if will be at frozen water machine evaporator, condenser, when compressor carries out the integration capability test operation, need purchase commercially available universal flow meter 21 respectively, electrodymamometer 22, temp probe T11～T14 and Data acquisition, device Data Logger23 etc. measure equipment, with its flow probe F11, F12, current probe C1 and voltage probe C2, install in

water pipe

14,15 and the appropriate location of compressor 13 power leads, at last with flowmeter 21, the numerical value that temp probe T12～14 and electrodymamometer 22 are measured, be sent to mobile computer 1 after seeing through data collector 23 arrangements, carry out data with the EXCEL software function again and compile whole, analyze.Yet, because of mostly being, universal instrument deals with the instrument that various different occasions are used, be that volume is big, price is high, unhandy Mobyneb, so when carrying out frozen water machine integration capability test operation, at least need prepare separately independently 2 flowmeters and contain flow probe, 4 temp probes, 1 electrodymamometer and contain electric current and voltage probe, 1 number of elements according to gatherer and 1 several expensive instrument such as mobile computer, very inconvenient; In addition, when checking the historical summary that records numerical value, all need the layout space of a whole page again, waste of manpower and man-hour, therefore, relevant dealer should be necessary to provide the integrated instrument and the software of special use, to improve the space of prior art disappearance at every turn.

The utility model content

Problem to be solved in the utility model is, at the prior art deficiency, provide a kind of with the prior art integral type frozen water machine integration capability test meter that integrates of standalone feature separately, to reduce the equipment cost, and more can simple and convenient in operating aspect, save man-hour.

For achieving the above object, the technological means that the utility model adopted is to provide a kind of integral type frozen water function power tester, it comprises the two flows probe of circumscribed, four temp probes, one current probe, one voltage probe and inner installing one a heat energy calculation IC plate, one casing of one an electric power calculation IC plate and a program-controlled device, this casing front is provided with a man-machine interface panel that can show various measurement numerical value and feature operation, this box back surface is provided with a socket backplate that connects those probe extended lines, the numerical value signal that those probes are recorded is sent to this heat energy calculation IC plate and this electric power calculation IC plate, and via this program-controlled device, after set software editing integration, be resent to a mobile computer.

In view of the above, the utility model aims at test frozen water machine integration capability and measures body and make, integrate flowmeter, the electric power of prior art and take into account the data collector function in one, and simplify distribution and special software is provided, the formula that becomes one tester, event is reduced volume and weight significantly, and except that can being convenient for carrying, the tool cost is low, operation easily reaches the advantage of saving man-hour.

Embodiment

For the utility model architectural feature, effect and other advantage can further be understood, now with preferred embodiment and cooperate graphic detailed description as after.

Please refer to Fig. 2 and cooperate shown in Figure 3, the utility model is a kind of integral type frozen water function power tester 3, the two flows probe F21 that mainly comprises circumscribed, F22, four temp probe T21～T24, one current probe C3, an one voltage probe C4 and inner installing one a heat energy calculation IC plate 311, the casing 32 of one electric power calculation IC plate, 312 and one program-controlled device 313 etc., casing 32 fronts are provided with the man-machine interface panel 33 that can show various measurement numerical value and feature operation, casing 32 back sides are provided with the socket backplate 34 that can connect various probe extended lines, can receive flow, temperature, electric current and voltage etc. record the signal of numerical value, 313 of program-controlled devices are responsible for receiving the signal from heat energy calculation IC plate 311 and electric power calculation IC plate 312, after set software editing integration, be resent to mobile computer 1, analyze, record and monitoring.The utility model is integrated the comprehensive function of frozen water machine integration capability test operation required flow measurement, temperature instrumentation, electric power instrumentation and data aggregation in one, this program-controlled device 313 is in advance according to the logical relation between desired data, change into controller specific program language, in view of the above as the foundation of program-controlled device 313 data processing.As shown in Figure 4, utilize the structure of the utility model 3 to be implemented after, utilize 1 flow probe F21, be contained on the frozen water pipe 14 of evaporator 11,2 temp probe T21, T22 are contained in respectively on frozen water pipe 14; And the cooling water pipe 15 of condenser 12 reaches into and out of cooling water pipe 15, and then same installing is 1 flowmeter F22 and other 2 temp probe T23, T24 in addition; Current probe C3 and voltage probe C4 then are installed on the power lead of compressor 13; When the frozen water machine turns round, the heat energy calculation IC plate 311 of the utility model frozen water function power tester 3 and electric power calculation IC plate 312, numerical value such as the flow that flow, temperature, electric current and voltage probe is measured, temperature, electric current and voltage, after calculating into earlier heat energy=flow * turnover temperature difference and electric power, be sent to program-controlled device 313, after set software editing integration, be resent to mobile computer 1 and perform an analysis, write down and monitor; And all measurement correlation parameters, all can be by 33 inputs of man-machine interface panel, setting.
