The characteristics of turborefrigerators and turbo-detanders whose standard sizes were adapted to parametric range of screw compressors are presented.</p>
<p>On the basis of ATR and appropriate compressors the air refrigerating units ARA are created, that have become the basis for freezing-refrigerating-thermal stations (MHTS) producing cold for quickfreezing apparatuses and also low potential heat.</p>
<p>Characteristics of a tunnel quick-freezing apparatus STAB, which obtains refrigeration from turborefrigerator are given, and its comparison with other types of tunnel apparatuses is carried out.</p>turbo expander unit, heat exchangermanagement and control bodiesтурбодетандерный агрегат, теплообменный аппараторганы управления и контроля
