Abstract: Hourly cooling loads in one year are calculated with the hourly simulation method for a refrigeration station in Hainan of China. On this basis, the life cycle costs of the main air conditioning equipments are calculated and the main influence factors are analyzed as a case study. The results show that the energy efficiency indexes of the main equipments are the most important parameters affecting the economy performance of a refrigeration station. It can produce not only remarkable energy conservation and emissions reduction benefits but also remarkable economic efficiency benefits with saving a lot of operation cost, to improve the energy efficiency level of water chillers and water pumps. So the high energy efficient equipments should be chosen on the design. The comprehensive evaluation method should be used on the equipment bidding and bid evaluation, and the weight of energy efficiency indicators should be increased greatly.

Key words: refrigerating station; air conditioning equipment; life cycle cost; energy saving
