    Functional Control ESIE07-03 3.12 Economizer Typical single compressor Principal application *To ensure equal distribution of gas, economiser line branches must be the same diameter, length and contain the same number of elbows TEV Equalising Line Evaporator Equaliser Line Condenser The compressor is provided with an economizer facility. This enables an additional charge of gas to be handled by the compressor, over and above that which is normally pumped.

As a guide to this effect, approximately half of the improvement due to using an economizer system will be lost by the time the compressor unloads to 90% capacity, and falls to zero at around 70% capacity.
