Through the sensor monitoring to the temperature, the humidity, the air absolute pressure and the flow of the air return opening and the air outlet, the data is transmitted to the PCI data acquisition card for judging the refrigeration performance status of the air conditioning unit; the testing device can fast test the refrigeration capacity of the air conditioning unit in an open environment, the constant temperature and the constant humidity of the air conditioning unit are not required to be maintained under normal working conditions, huge energy can be saved, the testing is faster, and the results are true and reliable.
Description
Technical field
The utility model relates to a kind of refrigerating capacity pick-up unit that is used for rolling stock air-conditioning unit, particularly a kind of air-conditioning unit refrigerating capacity device for fast detecting.
Background technology
At present, rolling stock air-conditioning unit refrigerating capacity pick-up unit has three kinds of arrangement forms: wind tunnel type, loop-type and room type.Comparatively Chang Yong arrangement form is: the auxilliary part of surveying adopts " wind tunnel type " to arrange, the main part of surveying adopts " room type " to arrange, in the main examining system, importing and exporting sampling measures evaporator import and export air condition respectively, accessory fan provides circulation power and regulates the pressure of inlet air, and flow measurement device measures the air circulation of pilot system vaporizer side." constant temperature and humidity room " in this system concentrated air handled (i.e. " room type "), to satisfy the needs of different testing engineerings.Basic demand to this " room ": (1) good airproof performance, (2) insulation, (3) have enough volumes.Sealing and insulation are carried out caloic exchange for preventing experimental system inner circulating air and the external world, guarantee stability that experimental system moves with and the precision of testing.Enough volumes have guaranteed that the wet exchange of " room " interior air heat fully carries out, and make in the room air condition even.Characteristics such as " room type " system of employing has compact conformation than other two kinds of forms, and floor area is little, and SR is little, and anti-interference is good, and operating mode is stable.Shortcoming is that energy consumption is big, and test period is longer, sets up and the maintenance cost height.
Summary of the invention
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, a kind of air-conditioning unit refrigerating capacity device for fast detecting is provided, can be in the actual refrigerating capacity of fast detecting rolling stock air-conditioning unit under the general environment, thus can be used for judging the air-conditioning unit through use or repair after the refrigeration performance situation.
The technical scheme that its technical matters that solves the utility model adopts is as follows: a kind of air-conditioning unit refrigerating capacity device for fast detecting, it is characterized in that forming and comprise: the pci data capture card, be installed on the return air inlet temperature sensor on the air-conditioning unit return air inlet fiberglass air channel, the return air inlet humidity sensor, the return air inlet pressure transducer, be installed on the air outlet temperature sensor on the air-conditioning unit air outlet fiberglass air channel, the air outlet humidity sensor, the air outlet pressure transducer, flow sensor, the end of probe of the sensor of described air-conditioning unit return air inlet one side is positioned at return air inlet fiberglass air channel, the end of probe of the sensor of described air-conditioning unit air outlet one side is positioned at air outlet fiberglass air channel, and the signal output part of described each detector is electrically connected with the corresponding signal input part of pci data capture card respectively.
The beneficial effects of the utility model are as follows: the utility model is monitored temperature, humidity, air absolute pressure and the flow of return air inlet, air outlet by each sensor that is arranged in air-conditioning unit return air inlet, air outlet fiberglass air channel, and pass to the pci data capture card by data line, be used to judge the air-conditioning unit through use or repair after the refrigeration performance situation; This refrigerating capacity device for fast detecting can be examined the air-conditioning unit fast and survey refrigerating capacity in open environment, need not guarantee lasting constant temperature, constant humidity under the specified environmental baseline of air-conditioning unit, saves a large amount of energy; Be not subjected to the artifact intervention, measure faster, real result is reliable, shortens the production cycle; And can dynamic calculation air-conditioning unit in the refrigerating capacity of environment in good time, also can calculate the actual refrigerating capacity of air-conditioning unit under the declared working condition, draw air-conditioning unit refrigeration performance basis for estimation; The various data that the pci data capture card of this pick-up unit obtains are by after computer software identification, calculating, and dynamically are presented at LCD screen with the style of virtual instrument.
