The invention provides a compression condensation
system with an ejector. The compression condensation
system comprises a recycled container, a
refrigeration compressor, the ejector, a condenser and a recycling container. When the compression condensation
system is used for a
refrigerant recycling system, compressor exhaust drives an ejected
refrigerant to enter the condenser together through the ejector, not all liquid refrigerants need to be completely evaporated into gas refrigerants which enter the compressor to be compressed, and temperature rise and
pressure rise are avoided, so that condensation loads are few; the gas refrigerants and the liquid refrigerants are recycled at the same time, the
running time is short, and the service life of the compressor is prolonged. The invention further provides a
refrigeration system with an ejector. The
refrigeration system comprises a gas-liquid separator, a
refrigeration compressor, the ejector, a condenser, a
throttle element and an
evaporator. When the refrigeration system with the ejector is used for a refrigeration system, compressor exhaust ejects liquid refrigerants of the gas-liquid separator through the ejector, the air suction and exhaust quantity of the compressor can be reduced at the request that cooling loads are constant, and thus
power consumption of the compressor is reduced; and the refrigerants can enter the condenser without completely passing the compressor, so that condensation loads are reduced.
