<p>A passive desuperheater for a vapor compression refrigeration system is disclosed. The passive desuperheater (11) includes a chamber (75) having two inlets (6,12) and an outlet (65), the first inlet (6) for introducing superheated gas into the chamber, the second inlet (12) for introducing cool liquid refrigerant into the chamber and the outlet (65) for outputting the desuperheated gas. The flow of cool liquid refrigerant into the chamber is generated by a gravity drop, resulting in the mixing of the liquid refrigerant with the superheated gas, such that desuperheated gas is output at the outlet. In an alternative embodiment, the hot discharge gas is input through the bottom of a shell and tube condenser (33) and then exposed to the cool liquid refrigerant in the condenser. The desuperheater according to the present invention also can be used to remove oil from the hot discharge gas during desuperheating. .</p> |
