Increasing the Reliability of Ship Refrigeration Units Through Permanent Control of Refrigerant Leakage

ანოტაცია

Refrigerating plants on board are used in refrigerating holds, gas carriers, and refrigerating chambers for receiving and maintaining low temperature, for conditioning air at all seasons, and other purposes. Separate elements of the refrigerating machines are cooled by fresh or seawater. That’s why the metal should be corrosion-proof. The installation should be lightweight, stand out with simple maintenance, be cheap, and economical.

It is necessary to keep not only the main operating parameters, but also to control the operation of its separate elements. It is important that the refrigerant does not have leakage of freon, which will cause the poisoning of the service personnel and ecological damage. Various kinds of sensors are used, which react to the leakage of freon. Practically, their acting is expressed by activating of alarm.

The purpose of this article is not only the discussion of activation of the signaling system of the refrigerating installation, but depending on the situation freon supply valve shut-off system and after a certain delay (if there was a delay in involving the personnel to eliminate the faculties), to discuss the action of shut off system of installation.
