Résumé

In this study, a compact gas-liquid separator using surface tension is proposed and its performance is evaluated. The gas bubbles are forced out from the micro grooves at the expanding section by the minimization effect of excess gas-liquid interface free energy, while the liquid phase remains confined inside the micro grooves. Two major limits of gas-liquid separation, i.e. (1) flooding limit at high liquid flow rate; and (2) entrainment limit at high gas flow rate are found and investigated. Dimensionless correlations for predicting gas-liquid separation limits are proposed. Then, a series of 4-16 kW capacity gas-liquid separators for practical R410A air conditioning system are developed. The volume of the separator is about 1/7 compared to the conventional separators. Pressure drop reduction by by-passing the gas from the evaporator is demonstrated in the real R410A cycle.
