(51) Int. Cl.
A refrigeration system can incorporate a cooling-liquid injec
tion system that can inject a cooling liquid into an interme
diate-pressure location of the compressor. The cooling liquid
can absorb the heat of compression during the compression of
the refrigerant flowing therethrough. The refrigeration sys
tem can include an economizer System that injects a refriger
ant vapor into an intermediate-pressure location of the com
pressorin conjunction with the injection of the cooling liquid.
A refrigeration system can include a liquid-refrigerant injec
tion system that can inject liquid refrigerant into an interme
diate-pressure location of the compressor. The injected liquid
refrigerant can reduce the discharge temperature of the refrig
erant. The liquid-refrigerant injection system can be used
with the cooling-liquid injection system and/or the econo
mizer system.
