Abstract:
An apparatus for cooling a product, comprising:a condenser structure;an evaporator structure comprising at least a first-evaporator section and a second evaporator section;a refrigerating circuit interconnecting the condenser structure with the evaporator structure;compressor means arranged in the refrigerating circuit between the evaporator structure and the condenser structure for pumping a refrigerant from the evaporator structure to the condenser structure;a heat exchanger structure incorporating the evaporator structure for promoting heat transfer from a product to be cooled to the evaporator structure; said heat exchanger structure comprising a first heat exchanger section incorporating the first evaporator section and a second heat exchanger section incorporating the second evaporator section; andmeans for leading the product to be cooled or an intermediate heat transfer medium from the first heat exchanger section to the second heat exchanger section;wherein said first evaporator section and said second evaporator section are separate in that each communicates separately with said compressor means.
