Summary

Success of international F gas agreements depends on effective measures taken responsibly. This paper describes monitoring of leakages based on data recorded using electronic logbooks according to EN 378 and Regulation (EC) No 1516/2007. Advantages of electronic data logging and reporting are shown on the possibilities of automatic analysis, fault detection and comparison, fast access to the full history of leak checks and various forms of output. Using the implemented system, service engineers can get a quick survey of their customers, cooling circuits, details of all maintenance work and repairs, refrigerants in store, refrigerants added, recovered, reclaimed, and disposed of. This is possible directly at customer sites using tablet and smartphone applications, which also enable the service engineers to create electronic logs of inspections in the field. Experience from reporting of HFC refrigerant emissions shows that the data required by the IPCC methodology divided into several categories of use is difficult to obtain from companies in practice. The concept underlying this work is to take advantage of electronic data logging and reporting, the possibilities of automatic analysis, fast access to the full history and various forms of output. Electronic data records from refrigerant handling on stock enable summarizing, reporting and analyzing important data in a chosen period. The Slovak data reporting system was launched into operation in the year 2009. We started dividing the data based on field of application in 2012. Weighted mean leakage for all applications, specifically for commercial refrigeration, air conditioning, transport refrigeration, heat pumps, industrial refrigeration, and domestic refrigeration, is calculated automatically. The historical development of the weighted mean leakage is analyzed according to the aforementioned fields of application. Data from the reporting system of monitored cooling circuits are compared with total leakages on national and international level. This paper is based on the activities of the Slovak Association for Cooling and Air-Conditioning Technology started in the year 2003 supported by the Ministry of Environment. The electronically led documentation was developed from the previous paper form. The evaluated data were collected from service organizations.
