Abstract
A heat exchanger is provided with stacked coil sections. Each of the stacked coil sections is configured to circulate a fluid independent from the other coil section. An air moving device is used to circulate air through both of the stacked coil sections. The stacked coil sections are positioned to have the air exiting the one coil section entering the other coil section.

A vapor compression system comprising:
- a first circuit to circulate a first refrigerant comprising a first compressor, first condenser and first evaporator in fluid communication;
- a second circuit to circulate a second refrigerant comprising a second compressor, second condenser and second evaporator in fluid communication;
- the first evaporator and the second evaporator being configured and positioned to exchange heat from a single process fluid;
- at least one air moving device to circulate air through the first condenser and then the second condenser;
- the first condenser and the second condenser each comprising a plurality of sections, each section of the first condenser being positioned next to and substantially parallel to a corresponding section of the second condenser;
- each section of the first condenser being thermally separate from the corresponding section of the second condenser;
- and
- a condensing temperature of the first refrigerant in the first condenser is less than a condensing temperature of the second refrigerant in the second condenser.
