    • Disclosed are cascade refrigerant systems for providing cooling of air located in an enclosure that is occupied by or which will be exposed to humans or other animals during normal use, wherein systems includes; (1) a first, relatively low temperature heat transfer circuit having a first evaporator located within the 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 comprising a second heat transfer fluid; (3) a heat exchanger which serves as the 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) in the high temperature loop of a heat exchanger which transfers heat from the second heat transfer fluid exiting from a high temperature condenser to the portion of the second heat transfer fluid which is traveling to the suction side of the compressor.
    • 公开了用于冷却位于在正常使用期间占据或将暴露于人类或其他动物的外壳中的空气的级联制冷剂系统,其中系统包括: (1)第一相对低温的传热回路,其具有位于外壳内的第一蒸发器和位于低温传热回路中的第一传热流体; (2)基本上位于外壳外部的第二传热回路,其包括第二传热流体; (3)用作低温回路中的冷凝器的热交换器,其通过将热量排出到第二传热流体中而与高温回路热耦合; 和(4)在热交换器的高温回路中,该热交换器将热量从从高温冷凝器排出的第二传热流体传递到传送到压缩机吸入侧的第二传热流体的部分。 p>
