Abstract

A dual circuit condenser for a cooling system is configured to cool refrigerant passing through the condenser. Operation of a first circuit of the system establishes a first temperature at a first area of the condenser, and operation of a second circuit of the system establishes a second temperature at a second area of the condenser. The condenser includes a manifold. The manifold is configured to receive a plurality of tubes. The manifold is further configured to define a first volume that is part of the first circuit and a second volume that is part of the second circuit. The manifold includes three or more separators interposed between the first volume and the second volume to segregate refrigerant in the first circuit from refrigerant in the second circuit.
