An apparatus includes a separator tank, a heat exchanger, a compressor-less heat separator, and a fluid cooler. The separator tank separates a first refrigerant into a vapor component and a liquid component. The heat exchanger is exposed to a load. The heat exchanger uses the liquid component of the first refrigerant to remove heat from a space proximate the load. The space includes at least one of a refrigeration unit and walk-in cooler or freezer. The compressor-less heat separator extracts heat from the vapor component of the first refrigerant and uses electrical power to move the heat to a second refrigerant. The fluid cooler removes heat from the second refrigerant.

Compressor-less cooling system

A heat exchanger for use with a furnace, each heat exchanger includes a plurality of heat exchanger elements. Each heat exchanger element includes a pair of clamshells sealingly attached to one another. The heat exchanger element includes a longitudinal axis. A pair of depressions are disposed in each respective said pair of clamshells. The depressions face one another to form a passageway wall and a serpentine fluid passageway therebetween. At least a portion of the serpentine fluid passageway extends along the longitudinal axis. A plurality of enhancements are formed in the depressions and are disposed within the portion of the serpentine fluid passageway. The plurality of enhancements project into the serpentine fluid passageway. Each enhancement constitutes a corrugation having a substantially trapezoidal longitudinal cross-section. A longitudinally positioned passageway wall portion is extended between each adjacently positioned enhancements within each clamshell.
