Abstract
An air-cooled condenser having cooling face areas so configurated as to form two closed or substantially closed nested loops in spaced relation to provide a common inlet air duct between the face areas communicating with an air mover; the cooling air passages through the loops being in generally opposed relation down stream from the common inlet duct. In one embodiment a section of the outer loop is displaceable for servicing the compressor.
Claims13
A condenser unit for air conditioning systems characterized by reduced cubic volume and high energy efficiency ratio comprising, in combination, a first annular closed loop heat exchanger coil having an outer side exposed to ambient air and an inner side defining a first chamber, a second annular closed loop heat exchanger coil within said first chamber having an inner side exposed to ambient air and an outer side communicating with said first chamber, said second coil defining a second chamber distinct from said first chamber, and a fan communicating with said first chamber inducing air flow through said first and second coils in opposed directions with respect to said inner and outer sides of said respective coils whereby ambient temperature air passes through each coil.
A condenser unit for all conditioning systems comprising, in combination, a base having a periphery and an inner region, outer flow-through air cooled coil means mounted on said base including a first heat exchanging closed loop coil defining a first chamber and having an air ingress side exposed to ambient air and an air egress side disposed toward said chamber and base inner region, inner flow-through air cooled closed loop coil means mounted on said base inner region within said outer coil means and first chamber defining a second chamber distinct from said first chamber, said second chamber being separated from said first chamber by said inner coil means, an opening formed in said base inner region, said inner coil means including a second heat exchanging coil having an air ingress side communicating with said opening and an air egress side communicating with said first chamber defined by said outer coil means, said first coil egress side communicating with said first chamber, and a motor driven fan for inducing air flow through said first chamber and through said first and second coils cooling the same, said first chamber defining an air flow passage directly establishing communication between said fan and said first and second coils whereby air passing through said first coil directly passes to said fan and air passing through said second coil has not previously passed through said first coil.
