Purpose & Contents
At present, Aspirator differ in shape and size according to the makers, but the research on each feature is slight. Therefore, the size, shape, ventilation system, internal structure and space size, sensor installation location are studied and proposes a standard specification of a aspirator.

In this Research, Each manufacture's aspirator and Thermometer screen(weather instrument shelter) were compared and analyzed. Also, the differences of natural ventilation type and forced ventilation type were analyzed intensively, and the influence of solar radiation and wind was analyzed.

We also designed and manufactured dual ventilated air circulators and applied for a patent.And the sensor unit constituting the temperature and humidity sensor is installed in a double plate structure in which a double ventilated air circulation path is formed in which the outside air is blocked, thereby minimizing direct solar radiation coming in from the surface of the aspirator, It is possible to accurately measure the temperature and humidity of pure air inside the aspirator by maximizing the external heat blocking effect, thereby improving the accuracy of the temperature and humidity measurement.

Results
The Aspirators operating in the Korea is analyzed and the standard specification of the Aspiratir according to size, shape, ventilation system, internal structure, space size and sensor installation position is presented, and the degree of Site measurement uncertainty is calculated, And the objective is to develop a standard shelter technology that can secure the world's highest or equivalent level of accuracy, and to develop a standard shelter technology that can contribute to securing the global market by introducing specifications.

There have already been many studies using aspirator outside the country. Apogee Instrument company performed comparative tests using Apogee model, RMyoung model, Met one model and so on. As a result of the test, it was confirmed that the errors of each aspirators occurred by season,In order to reduce this error, the influence of the solar radiation using the air barrier was minimized by using double or triple shielding.Such a study did not proceed in Korea.

For this research, the aspirators developed by each manufacturer and the aspirators of the managing department were installed in the observation field, and operation and data collection were performed. Using the collected data, the temperature / humidity values measured for each aspirator were compared and analyzed.

The appearance and ventilation of the aspirator differed by manufacturer.For comparative testing according to these characteristics, the temperature and humidity sensors in the aspirator were placed in the Thermometer screen(weather instrument shelter) to perform the calibration test.

Aspirators are largely classified into natural circulation type and forced ventilation type according to the ventilation type. In case of forced ventilation type, it is measured by sucking ambient air using a fan, and in the case of natural ventilation type, it is measured by exposure to the surrounding environment.

Overall, the forced ventilation system reacts more sensitively than the natural circulation system, resulting in a temperature/humidity measurement error.

In addition, the influence of the inner volume of the shading box was analyzed, and it was understood that the influence of the ambient air change can not be followed if the volume inside the shelter is too large.

Large Thermometer screen(weather instrument shelter) were larger in internal volume than other aspirators and did not respond sensitively to changes in temperature / humidity with day.

The development of a aspirator is also important in the appearance, but the influence of the surrounding environment should be considered.

Especially, it is affected greatly by solar radiation and wind(wind speed), and it is necessary to develop a aspirator to take this into consideration.

In this research, the prototype was developed by considering the effect of ventilation system, internal volume, solar radiation and wind direction.

Compared with the natural circulation type, the forced ventilation type(ventilation rate : 4~5 ㎧) is more sensitive to the temperature and humidity changes of the ambient air and more accurately measured. Also, the double ventilation system minimizes the influence of solar radiation and albedo. In addition, fan failure due to external exposure is frequent, so fans are installed on the side of the third prototype for maintenance

The results of this research show that the measured values of temperature and humidity vary depending on the external shape of the air circulator and the external environment. In order to minimize the effects of solar radiation and wind, the prototype is made of forced ventilation, which is sensitive to changes in the surrounding environment. It was also developed to measure more accurately by blocking heat from the outside through double ventilation type.

Expected Contribution
□ Ensuring high quality data by homogenizing uncertainties other than temperature and humidity observation sensors
□ Acquired standard of temperature and humidity observation by adopting standard of Aspirator
