Device for separating oil from a refrigerant fluid

Abstract

A device for separation of oil particles by a coolant for air conditioning systems comprises a hollow container body and an inlet arranged to make enter the hollow container body a coolant, with oil particles, mainly in liquid phase and have a temperature T. The device also comprises a outlet located upper part of the hollow container body and arranged to cause protrude coolant regenerated in vapour phase by the hollow container body. is also provided a heating coil arranged in the hollow container body and containing fluid at a temperature T>>T, in such a way that the coolant evaporates when comes in contact with the heating coil and the oil particles rimangano instead on the bottom of the hollow container body. The device also comprises a first oil barrier arranged above with respect to the heating coil and arranged to avoid that the oil particles schizino towards the outlet. is also provided a second oil barrier 114 located in the hollow container body at the outlet, said second oil barrier comprising holes having a diameter of a predetermined value D configured for preventing to oil particles of larger diameter to the predetermined value D of crossing the outlet.
