Refrigerated transport

Refrigerated transport has a lot of analogies with refrigerated storage, but also a distinct difference: movement from A to B.

This movement has multiple consequences:

• First: space and weight limitations to the climatization equipment, as one is paid to carry goods, and not the climatization installation, from A to B.
• Second: versatility in application domain. After moving e.g. pears at -1.0 °C from A to B, it is effective to move a new cargo from B to C and that may e.g. be frozen fish at -22 °C.
• Third: uncertainty about ambient conditions. When building a storage facility in location X meant to operate in only 6 months of the year the expected range of ambient conditions can be in a pretty narrow band. Transport equipment moving from A to B to C to wherever at any time of the year should be prepared for a much broader ambient conditions.

This means that the moving refrigeration system needs our special attention. For example, the diversity of cargos and ambient conditions results in a diversity of frost loads to the evaporator making defrost control in transport more challenging than in storage, and making the need for good automatic defrost control more pressing.
