Abstract
A refrigeration condenser has at least two serpentine paths of unequal lengths (effected by unequal numbers of loops in the paths) extending between common inlet and outlet ports. By adding this design capability to the conventional equal path length condensers greater design flexibility is provided to permit smaller incremental size changes from conventional equal path length condensers, and allows inlet and outlet ports to be on the same side or on opposite sides without any change in condenser size or performance.
Claims3
A condenser for a refrigeration system, the condenser having an inlet and an outlet, comprising;
- at least two parallel flow passages all laying in a common plane and connecting the inlet to the outlet, each flow passage comprising a serpentine path having a sufficient number of passes across the condenser so that each passage extends from the inlet to the outlet,
- the flow passages having different numbers of passes thereby having unequal lengths.
A condenser for a refrigeration system, the condenser having an inlet and an outlet, comprising;
- two parallel flow passages laying in a common plane and nesting with each other and connecting the inlet to the outlet, each flow passage comprising a serpentine path meandering across the whole area of the condenser so that each passage extends from the inlet to the outlet,
- one flow passage having two more passes than the other passage thereby having a greater length than the other passage.
A condenser for a refrigeration system, the condenser having an inlet and an outlet, comprising;
- two parallel flow passages laying in a common plane and connecting the inlet to the outlet, each flow passage comprising a serpentine path meandering across a portion of the condenser area substantially exclusive of the other passage so that each path extends from the inlet to the outlet,
- one flow passage having two more passes than the other passage thereby having a greater length and covering a greater portion of the condenser area than the other passage.
