Document Type and Number:
Japanese Patent JP2023113811
Kind Code:
A
Abstract:
To provide a cascade refrigerant system for providing cooling of air located in an enclosure which is occupied by or which will be exposed to humans or other animals during normal use.SOLUTION: A cascade refrigerant system includes: (1) a first, relatively low temperature heat transfer circuit having a first evaporator located within an enclosure and a first heat transfer fluid in the low temperature heat transfer circuit; (2) a second heat transfer circuit located substantially outside the enclosure and including a second heat transfer fluid; (3) a heat exchanger serving as a condenser in the low temperature circuit thermally coupled with the high temperature circuit by virtue of rejecting heat into the second heat transfer fluid; and (4) a heat exchanger in a high temperature loop which transfers heat from the second heat transfer fluid discharged from a high temperature condenser to a part of the second heat transfer fluid which is sent to a suction side of a compressor.SELECTED DRAWING: Figure 1
