Abstract: It is studied the energy-saving reconstruction of the existing household refrigerator performance laboratory, proposed the energy saving scheme, and compared the energy-saving accounting and the actual energy-saving benefit after the energy-saving reconstruction. We found that the energy-saving benefit can reach more than 20% from the energy-saving accounting or from the actual test comparison data after the energy-saving reconstruction. Through the economic analysis, the payback period for cost of the energy-saving reconstruction is about two years.

Key words: Performance laboratory, Energy saving, Energy-saving benefits
