New installations for rapid freezing of foodstuffs with low-temperature air expanded in a turbo-expander

Arkharov A.M., Kobulashvili A.S., Rosenoer T.M., Zhuravleva I.N., Wenger K.P., Antonov A.A.


A possibility of use of turborefrigerators of type ATR working on the principle of the air refrigeration cycle for food technological processes is considered. The characteristics of turborefrigerators and turbo-detanders whose standard sizes were adapted to parametric range of screw compressors are presented.

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.

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.

Features of designing air conditioning systems according to new building codes

Kokorin O.Y.


New standards with regards to systems of heating, ventilation, air conditioning and building climatology introduce considerable changes when choosing the regimes of preparation ofthe conditioned air. A higher humidity of the outside air design parameters has required obligatory use of the regimes of refrigeration and drying of the inlet outside air. Based on the use of York equipment, energy efficient air conditioning systems are being developed.

Features of the design of ventilation and air conditioning in the buildings of medical institutions (HCI)*

kollegiya R.


The calculated air temperatures in the serviced area of the premises are determined depending on their purpose in accordance with tables 9 and 10, both for the cold and for the warm period of the year. In the operating room, the air temperature is not more than 22 °C. The relatively low temperature is explained by the increase in the concentration of bacteria during operations and the deterioration in the heat transfer of personnel due to the use of rubber gloves and masks with increasing temperature.

Cartridge pressure switches type ASV (Saginomiya)

Shishov V.V.


Pressure switches must protect the refrigeration plant from too high discharge pressure and low compressor suction pressure. Increasing the discharge pressure above a certain value can lead to an accident: destruction of the refrigeration unit, jamming of the compressor, burning of electrical windings. Significant reductions in suction pressure impair oil return to the compressor and may also freeze water or ethylene glycol in chillers.
