Refrigeration system
Abstract
Abstract A refrigeration system having a compressor and a condenser, a pipeline connected between the compressor and condenser and a filter-dryer heat exchanger connected to a high gas velocity ejector built into a pipeline between the compressor and condenser. This ejector is formed by a port through which passes refrigerant gas at high velocity. At the discharge end of this port a pipe of small diameter is inserted to the exact spot which will cause a suction to be drawn on it, thus creating the ejector effect. The suction on the small-diameter pipe causes hot refrigerant gas to be drawn from a hot gas discharge line through a filter-dryer heat exchanger of large size where the hot gas is filtered and cooled so it will change to a liquid in the small diameter pipe and be ejected back into the main hot gas line as a cool liquid refrigerant by the action of the ejector. The ejector is of large port design so as not to cause back pressure on the main refrigerant system.
