Title:
TWO-PHASE REFRIGERANT DISTRIBUTION SYSTEM FOR MULTIPLE PASS EVAPORATOR COILS
Document Type and Number:
WIPO Patent Application WO2005091793
Kind Code:
A3
Abstract:
A multiple pass, parallel tube heat exchanger with a collection header extending along the length of each of a first and second pass, is provided with a bypass tube which fluidly interconnects the downstream end of the collection header to a midpoint thereof, near the end of the first pass tubes and the beginning of the second pass tubes so as to enhance the flow distribution of two-phase refrigerant from the collection header to the second pass tubes. The distribution flow is further enhanced by the insertion of an eductor nozzle within the collection header, and with the inlet of the eductor nozzle being supplied by refrigerant flow from the condenser to thereby provide a motive flow of two-phase refrigerant in the loop which includes the latter half of the collection header and the bypass tubes.
