- Every kW of cooling at the evaporator becomes roughly 1.2 to 1.4 kW of heat at the condenser. In cold chain logistics heat recovery, that reject stream is steady and sizable — ideal for space or water heating.
- Heat reclaim coils on the rack condensers feed a glycol loop. A storage tank buffers the loop for morning peak demand. Domestic water preheat takes priority; space heating is the spillover load.
- Metric Outcome Natural gas for water heating minus 52% Condenser fan runtime minus 9% (lower head pressure) Simple payback about 2.4 years
- The same reclaim logic appears in supermarket retail heat recovery and food processing heat recovery, where compressors run year-round. Low return temperatures and continuous operation make cold-chain sites among the best heat-recovery candidates.
티his cold chain heat recovery case study looks at a refrigerated distribution center that captures condenser reject heat to warm the dispatch area and preheat sanitation water, instead of dumping it outdoors.
