Abstract

The base of a rational use of natural cold is the application of air heat exchangers in refrigerating installations.

Thus, it is practical to use an air superchiller of liquid ammonia. This will ensure a more stable operation of the ammonia pump switched on at low temperatures of the outside air and installed after the vertical receiver.

A heat exchanger based on porous materials with the average coefficient of heat transfer 65 Wt/(m2*K) was used as an air superchiller.
