What is Commercial Refrigeration Part 2

Life Cycle Climate Performance (LCCP)

commercial cold storageWhat are the types of commercial refrigeration? Fluorocarbon replacements for CFC-502 and CFC-12 include HCFC-22, HCFC-22 based blends, HFC-134a, -404A and -507. Other fluorocarbon differences can also be used although huge system process modifications will be required to manage properly the pressure hazard potential and fire/explosion. This of course greatly increases the cost. An analysis of four differing system processes was performed using LCCP for a typical U.S. supermarket constructed in 1999 of 5,680 sq. M (60,000 sq. ft.). The results show:

The distributed systems with HFCs are clearly the right choice based on LCCP. The HFC-404A or -507 distributed system had an LCCP less than half the direct expansion system and was at least 20% better than either non primary loop system. The secondary loop system with ammonia has an LCCP similar to that of the secondary loop HFC system. A 1999 report by A. D. Little estimates that using ammonia would add costs of $660 million per year in the U.S. alone due to additional safety equipment, hardware and increased energy consumption.

HFCs --- The Balanced Solution to Commercial Refrigeration

When all ideas and results are considered, HFCs offer the best solution for meeting the requirements of the commercial refrigeration industry. Commercially available throughout the world, HFCs are energy efficient, low in toxicity, cost-effective, can be used safely and are reusable. When used in energy efficient applications, their excellent LCCP reduces fossil fuel consumption and with it emissions of carbon dioxide, the most prevalent greenhouse gas.
