Description

Leak test method selection system and method of air conditioning equipment {AIR CONDITIONING EQUIPMENT LEAK TEST SELECTION SYSTEM AND METHOD}

The present invention relates to a system and method for selecting a leak test method for an air conditioning facility, and relates to a technology for selecting an appropriate leak test method for the facility.

Air conditioning facilities are installed in nuclear power plants, and for smooth operation of the air conditioning facilities, on-site leakage tests are conducted to check the system periodically.

Air conditioning equipment circulates outside air and inside air to ventilate the inside air of the site. At this time, external foreign substances or impurities are filtered out, and a cooler for maintaining the internal temperature and a pneumatic device for generating air pressure are provided to maintain the working environment inside the power plant in an optimal state.

Since the operation of the air conditioning facility maintains the operation of all sites, the maintenance of the air conditioning facility is one of the very important items.

For the on-site leakage test of air conditioning equipment, the leakage test method for the entire system and individual components constituting the facility is applied, and the constant pressure method and the pressure decay method are used for the leakage test method. At this time, the tester selects the appropriate test method for the facility depending on subjective judgment according to the entire facility or individual components.

However, even if one of the constant pressure method and the pressure damping method is selected by subjective judgment of the tester, there is a problem in that the time and cost required for the test increase due to repeated trial and error of the leak test because there is no selection standard for this.

In order to solve this problem, it is necessary to develop appropriate test methods for the entire facility and individual components constituting the facility by establishing standards for on-site leakage testing and devising a methodology for target facilities that perform leak testing.

If individual components are designated as a group, a leak test method can be selected according to the volume and leak rate of the individual components designated as a group, and the volume and leak rate can be changed by the tester.

At this time, if the volume of the individual components is greater than A and the leak rate is less than B, the pressure decay method is performed, and otherwise, the leakage test of the individual components may be performed by performing the constant pressure method.

If the leakage amount between the entire facility and individual components constituting the facility is less than the allowable value, the result is recorded and the test is terminated. quit If it is possible to divide the small volume, perform the constant pressure method again to check if the leakage is less than the allowable value, record the result, and end the test.
