Facilities meeting one or more of the following criteria may benefit from this opportunity.
- Large temperature differentials across doors
- Doors are in high use areas therefore left open
The walk-in cooler currently has strip curtains behind the door to reduce energy loss through the door when it is open. However, strip curtains only block a small amount of energy loss. Quite a bit of energy is lost around the strip curtain edges. There were 6 inch gaps along the sides of the strip curtains, and a 12 inch gap along the bottom, letting cold air flow out and warm air flow in. This added heat load needs to be rejected by the refrigeration system to maintain the target cooler temperature.
High speed doors controlled by motion sensors significantly reduce the time cooler doors are open. Based on conversations with plant personnel, cooler doors are left open 8 hours a day, 5 days a week. Replacing existing standard roll-up doors with high speed roll-up doors controlled with motion sensors could reduce the time doors are open to 5%.
These templates are excel based spreadsheets that quickly and easily help users quantify energy savings, cost savings, implementation costs, and payback. The excel spreadsheets then automatically write a professional looking report for users to utilize as they see fit.
