FUR ANIMAL BREEDING PLANT

摘要

FIELD: agriculture; farms for breeding valuable races of fur animals. SUBSTANCE: raising of fur animals in summer period and in hot climatic zones is carried out in plants having premises with cooled air circulation system. Cold is generated in cooling machines which utilize pressure differential of natural gas. They are installed at gas-distribution stations and substations and transmit cold first through heat exchanger to transporting cooling agent (water solution of ethylene glycol) and then through cooler medium to ambient air. Used in the function of cold generator located at stations: gas-expansion machine, pulsing gas coolers, vortex tubes. EFFECT: high overall efficiency. 3 cl, 2 dwg
