Why It Matters

Cold stores continually introduce warmer make-up air and run defrost cycles, both of which add load to refrigeration. Recovery trims that load and eases compressor runtime.

Typical Energy Savings

Pre-cooling incoming air with exhaust can reduce refrigeration energy by 10 to 25 percent depending on climate and door traffic.

Recommended Technology

• Plate cores sized for low face velocity
• Defrost strategy matched to the coldest design point

What to Watch

• Frost on the core in very cold intake conditions
• Hygiene and drainage in food-grade stores
