Abstract
The research work focused on validation of the climatic conditions for the new-design testing room for the freezer that comply with the testing standard. The testing room using reasonable investment cost could function well. The developed system cost about 45% of the standardized system. It was applicable for the medium size freezer manufacturers. The system was designed, fabricated, assembled, successfully installed and tested by the freezer manufacturer. The system test was conducted under design conditions satisfying the end-user requirements. The test results fulfilled the desired research objectives, maintaining climatic conditions, with suitable performance to obtain the test results required by the proposal for approval certification of the standard room. However, the system was unable to maintain long-term stable operation beyond 5 consecutive days. Inside the testing room, wide-range fluctuated temperature and relative humidity has shown, and requiring air-conditioning system restart. The system could be further improved by upgrading control strategy of the fix-speed compressor and changing the front door rubber seal for cooled air leakage prevention.
