Abstract
The utility model discloses a kind of thermal comfort index PMV proving installation, it comprises LCD display, keyboard, A/D conversion, 51 monolithics, air themperature probe, WBGT probe, humidity measurement probe, wind speed test probe.Air themperature probe described in utilization, WBGT probe, humidity measurement probe, the test of wind speed test probe mean radiant temperature, air dry-bulb temperature, relative air humidity, wind speed, be input to 51 single-chip microcomputers and carry out calculating PMV and outputting to PC.The utility model structure is simple, with low cost, test is accurate.
Description
Technical field
The utility model relates to architectural environment technical field of measurement and test, particularly the proving installation of air-conditioning Thermal Comfort Parameter PMV.
Background technology
Traditional air-conditioning indoor thermal comfort is evaluated and is controlled general employing indoor temperature and humidity two parameters, but these two parameters can not reflect human comfort's degree completely, the factor of actual influence human comfort is except temperature and humidity, also comprise wind speed, mean radiant temperature, human body clothing thermal resistance and human metabolism to lead, human body is the result of these combined factors to environmental amenity perception.Therefore adopt merely temperature and humidity very unreasonable as the evaluation index of thermal comfort, and the air-conditioning system directly using temperature and humidity as controlled parameter, its comfortableness is poor, energy consumption is higher.PMV(Predicted Mean Vote, namely average votes is predicted) index is the evaluation index of the sign human thermal response that professor Fan Geer of Denmark proposes at first, represent the mean value of the cold and hot sensation of most people in same environment, its value is relevant to 6 factors such as temperature, humidity, wind speed, mean radiant temperature, clothing thermal resistance and human metabolism.The key that thermal comfort index PMV applies is its method of testing and technology.At present, the research of domestic and international PMV test macro and device aspect is less, and practical application is less, and is all off-line test technology, can only be used for the evaluation of thermal comfort, can not be used for the real-time control of air-conditioned room thermal comfort; In addition, at present PMV test macro and device be import equipment mostly, system is comparatively complicated, and precision is not high, expensive.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model calculates theoretical model based on PMV, utilize microelectric technique, devising a set of take single-chip microcomputer as the PMV test macro calculating core, provide a kind of structure simple, easy to use, test accurate, cheap PMV proving installation, this device both can be used for the off-line test evaluation of thermal comfort, can be used for again air-conditioning system and controlled in real time.
The technical scheme solved the problem is: adopt WBGT probe, air themperature probe, wind speed test probe, humidity measurement probe, 51 single-chip microcomputers, A/D converter, keyboard, LCD display composition PMV test macro.WBGT probe, air themperature probe, wind speed test probe, humidity measurement probe test the parameters such as mean radiant temperature, air dry-bulb temperature, relative air humidity, wind speed respectively, analog test signal converts digital signal to through A/D converter and is input to 51 single-chip microcomputers, and clothing thermal resistance and metabolic rate two parameter values are set by input through keyboard.Like this, 51 single-chip microcomputers just by calculating pmv value, and can be outputted to LCD display or air conditioning system controller.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is integrated with PMV computation model and microelectric technique, devising with single-chip microcomputer is calculate the PMV proving installation of core, system electrical element have low in energy consumption, stable, realize the advantages such as simple; This proving installation can be used for air-conditioning system and controls in real time simultaneously, reaches comfortable and energy-conservation object.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is utility model works schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
As shown in Figure 1, a kind of PMV proving installation comprise LCD display 1, keyboard 2, A/D converter 3,51 single-chip microcomputer 4, air themperature probe 5, WBGT probe 6, humidity measurement probe 7, wind speed test probe 8, air themperature probe 5, WBGT probe 6, humidity measurement probe 7 and wind speed test probe 8 be connected to the input interface of A/D converter 3 by cable.The output interface of A/D converter 3 and keyboard 2 are connected to the input interface of 51 single-chip microcomputers 4.The output interface of 51 single-chip microcomputers 4 is connected to LCD display 1.
As Fig. 1, shown in 2, first by keyboard 2, clothing thermal resistance and metabolic rate are input to 51 single-chip microcomputers 4, then 51 single-chip microcomputers 4 wait for that A/D converter 3 is by air themperature probe 5, WBGT probe 6, humidity measurement probe 7, the mean radiant temperature that wind speed test probe 8 is surveyed, air dry-bulb temperature, relative air humidity, the simulating signals such as wind speed convert digital signal to, after converting, 51 single-chip microcomputers 4 calculate pmv value by performing the PMV calculation procedure woven and output in LCD display 1, when controlling in real time for air-conditioning system, pmv value is outputted to simultaneously the signal incoming end of air-conditioner controller.
