METHOD OF ENERGY SAVING IN REFRIGERATION EQUIPMENT Russian patent published in 2008 - IPC F25B45/00 

FIELD: heating.

SUBSTANCE: method provides enrichment of regular refrigerant with surface-active agent directly in refrigeration equipment. For that purpose necessary amount of surface-active agent is supplied into empty and clean or after Freon similar to regular refrigerant balloon, then balloon is connected with refrigeration equipment, refrigeration equipment is switched in working mode, when regular refrigerant is supplied into balloon with surface-active agent, balloon weight is continuously monitored, and in case of its slight increase refrigeration equipment is switched off, time interval is maintained for creation of Freon in balloon, which is enriched with surface-active agent, after that refrigeration equipment is prepared for Freon filling mode and is again connected, then Freon enriched with surface-active agent is pumped away from balloon into refrigeration equipment. On completion of pumping process refrigeration equipment is switched off, then it is again connected into working mode for 3-5 minutes for distribution of enriched refrigerant in refrigerating circuit, after that it is disconnected, then procedure of refrigerant enrichment is repeated without addition of surface-active agent into balloon.

EFFECT: reduction of power inputs with simultaneous simplification of enrichment procedure.
