Project Background

During operation, the exhaust air from quick-freeze tunnels and cold-storage warehouses carries away large amounts of cooling/heating energy.

Challenges

Refrigeration load is high and store-temperature swings affect food quality.

Solution

Install on the supply/exhaust sides:Rotary Heat Exchanger, recovering exhaust energy to pre-treat the incoming air.

Results

Refrigeration-unit load reduced by 10%, with reduced cold-storage temperature fluctuation and smoother operation.

食品冷冻冷藏的能量回收

冷冻冷藏车间制冷负荷大，排风中携带冷量。通过转轮换热器回收排风冷量，用于预冷进入的新风或相邻区域，可降低制冷机组能耗。在生鲜加工与冷链物流中，这一措施能显著缩减运行成本，提升系统能效。

防结霜与卫生

冷冻排风含湿大，回收冷量需注意防凝水与卫生设计避免交叉污染，选用易清洁结构以符合食品行业规范。

防结霜与卫生

冷冻排风含湿大，回收冷量需注意防凝水与卫生设计避免交叉污染，选用易清洁结构以符合食品行业规范，保障食品安全，同时降低制冷机组的运行负荷。

冷链改造需兼顾卫生与能效，建议在方案阶段就与食品工程师确认规范，并核算全年冷量回收量以评估回报，避免只看重设备价格而忽略系统匹配。需要选型方法可参考选型完全指南。

建议在方案阶段与食品工程师共同确认卫生规范，并核算全年冷量回收量，用可量化的回报支撑改造立项，避免只关注设备单价而忽视系统匹配与合规要求。
