AGGREGATED REFRIGERATING SYSTEM WITH LOW AMOUNT OF REFRIGERANT Russian patent published in 2019 - IPC F25D11/00 

FIELD: refrigerating equipment.

SUBSTANCE: present invention relates to an aggregated, liquid, recirculating refrigeration system with an amount of refrigerant of less than 10 pounds per ton of cooling capacity. Refrigerating system comprises coil of evaporator, structure for separation of steam from liquid, compressor of refrigerating unit, condenser of refrigerating unit, expansion device on side of high and low pressure, capacity for collection of coolant, refrigerant line connecting outlet of expansion device with inlet of structure for separation of steam from liquid and configured for delivery of liquid refrigerant to structure for separation. Structure for separation of steam from liquid has outlet of liquid, which is connected through refrigerant line to inlet of evaporator. Structure for separation of steam from liquid, compressor, expansion device on side of high pressure, said reservoir for collection of coolant and expansion device on side of low pressure are located inside pre-aggregated modular engine compartment. Method for reducing the amount of refrigerant per ton of cooling capacity in a refrigeration system is characterized by the presence of an evaporator, a liquid separator from the steam, a compressor and a reservoir for collecting coolant and includes arrangement of compressor, separator of liquid from steam and reservoir for collection of coolant in prefabricated modular engine compartment. Condenser is mounted on the roof of modular engine compartment in case of condenser with air cooling. Evaporator is connected with modular engine compartment through refrigerant line.

EFFECT: ammonia in the system is released into the surrounding space without significant harm to people or the environment.
