General Suggestions
Consider the following general recommendations regarding steps that can be taken on a regular basis to help keep refrigeration systems running properly and efficiently:
- Report and repair any pipes that are vibrating.
- Make sure the control settings for the refrigeration system are easy to find and interpret for ease of system tuning and adjustment.
- Keep the doors to cold storage areas closed whenever possible.
- Make sure that cold storage areas are not cooled to a lower temperature than is truly needed (refrigeration system energy use increases by 1% to 3% for every degree (F) of additional cooling).
- Make sure that products are not stacked directly under or in front of evaporators in cold storage units.
- Minimize other heat sources (such as lights and forklifts) in cold storage areas, which produce heat that must be removed by the refrigeration system.
- Report the formation of ice on cold storage area floors and walls. Ice indicates that a lot of air is entering the cold storage area, which carries moisture that gives off heat as it freezes, adding to the refrigeration load.
- Switch off system pumps and fans (such as those used for circulating cold air, chilled water, or anti-freeze) when not required. Pumps and fans can add significant heat loads to the refrigeration system during operation.
- Report and repair damage to refrigeration system pipe insulation.
- Regularly check compressor oil levels to ensure proper lubrication.
- Report and repair any refrigerant leaks.
