METHOD AND SYSTEM FOR DISTRIBUTION OF AN EXPANDING LIQUID

摘要

A heat exchanger system has a circuit with a condenser (1), pressure altering means (2; 14), an evaporator (3) containing a distribution header (5) fluidly connected via restrictors (9-12) to several fluid channels (8) coupled in parallel and a compressor (4). The outlet of the condenser (1) is connected to the inlet of the pressure altering means (2; 14), the outlet of the pressure altering means (2; 14) is connected to the inlet of the evaporator (Z), the outlet of the evaporator (3) is connected to the inlet of the compressor (4), and the outlet of the compressor (4) is connected to the inlet of the condenser (1). The circuit contains a refrigerant and the system includes: (a) means for lowering the temperature of the refrigerant downstream of the condenser and upstream of the pressure altering means; and/or (b) means for changing the pressure including means capable of increasing the pressure of the refrigerant downstream of the condenser, so as to keep the refrigerant from flashing until it passes the restrictors (9-12), thereby obtaining a one-phase liquid refrigerant flow in the distribution header (5).
