Abstract
A heat exchanger is disclosed that includes a plurality of parallel refrigerant paths, and a refrigerant injector operatively associated with an inlet to each refrigerant path for independently metering single phase refrigerant into each of the parallel refrigerant paths.
Claims15
A heat exchanger comprising:
- a) a plurality of parallel refrigerant paths;
- and
- b) a refrigerant injector operatively associated with an inlet to each refrigerant path for independently metering single phase refrigerant into each of the parallel refrigerant paths.
A heat exchanger comprising:
- a) a plurality of alternating refrigerant and hot fluid layers arranged in a parallel configuration;
- b) a refrigerant injector operatively associated with an inlet to each refrigerant layer for metering single phase refrigerant into each of the refrigerant layers;
- and
- c) a distribution manifold for delivering single phase refrigerant to each of the refrigerant injectors.

A method of distributing refrigerant in a heat exchanger having a plurality of parallel refrigerant flow paths, comprising the steps of:
- a) associating a refrigerant injector with each refrigerant flow path of the heat exchanger;
- and
- b) independently injecting single phase refrigerant into each of the refrigerant flow paths of the heat exchanger to maximize the performance of the heat exchanger.
