Abstract

On the base of analysis heat exchanging process from a wall of the heat-exchanging device to sublimating or welding refrigerant the simple and universal mathematical model of this process is created. The system of dimensionless criteria is produced and the form of the criterion equation, allowing describe a wide circle of processes with sublimating or welding of a refrigerant on a working surface is found. By comparison of the experimental and settlement data the good conformity of results of accounts and experiment is confirmed. The application of the received equations will allow improving designs of heat-exchanging devices.
