ABSTRACT:
In a refrigeration system, a centrifugal economizer discharges liquid towards an evaporator through a wholly static restriction (17), the dimension of which is chosen so as to allow no gas or little gas to escape with the liquid at the conditions of maximum pressure ratio in permanent operation. When the pressure ratio is lower, the flow rate allowed by the restriction tends to decrease with respect to the flow rate delivered by the compressor. This entails an increase in the radial thickness of the liquid ring in the centrifugal device. This in turn increases the pressure upstream of the restriction, whereby compensating the initial tendency of the flow rate to decrease through the restriction.
