Abstract
A refrigeration system of the type having a compression stage, a condensation stage, an expansion stage and an evaporation stage, comprising a first evaporator group in the evaporation stage. The first evaporator group has two or more evaporators. A first valve is positioned upstream of the evaporators of the first evaporator group. The first valve is closeable to stop a supply of refrigerant to the evaporators of the first evaporator group simultaneously for a subsequent air defrost of the evaporators of the first evaporator group.
Claims10
A refrigeration system of the type having a compression stage, a condensation stage, an expansion stage and an evaporation stage, comprising:
- a first evaporator group in the evaporation stage, the first evaporator group having at least two evaporators, the at least two evaporators of the first evaporator group being in separated refrigerated enclosures;
- and
- a first valve positioned on a line common to the at least two evaporators of the first evaporator group, the first valve being closeable to block a supply of refrigerant to the at least two evaporators of the first evaporator group simultaneously for a subsequent air defrost of the at least two evaporators of the first evaporator group.
A method for stopping a supply of refrigerant to evaporators of a refrigeration system of the type having a compression stage, a condensation stage, an expansion stage and an evaporation stage, for a subsequent air defrost of the evaporators, comprising the steps of:
- providing a valve in a line common to at least two evaporators of the evaporation stage, the at least two evaporators being in separated refrigerated enclosure;
- and
- closing the valve so as to block the supply of refrigerant to the at least two evaporators simultaneously.
