forangare for a circuit, serskilt intended to tillforsekra constant overhettning of kylgasen and a balanced effect in the individual circuits

摘要

An evaporator for a refrigerating cycle, particularly useful to ensure constant superheating of the refrigerating gas and a balanced efficiency of the individual circuits comprises an inlet duct (1), a flow regulating control valve (2) downstream thereof, a distributor (3), downstream of the control valve (2), feeding a plurality of primary circuits (4,5,6,7) wherein the refrigerating fluid is evaporated and a common outlet manifold (8), there being provided a further circuit (9) downstream of the manifold (8) wherein the evaporated fluid is superheated. Means (11) are provided for controlling the superheating step in the further circuit (9) by actuating the flow regulating control valve (12) located upstream of the distributor (3). IMAGE
