Summary

 
Refrigeration equipment is not provided on many small fishing vessel projects. It is proposed to install absorption refrigerating machines (ABRM) as refrigeration units for small vessels of the fishing fleet, the working medium of which is a waterammonia mixture. Such machines can operate by using the heat of exhaust gases, that is, receive energy from internal combustion engines. Ship power plants, unlike stationary ones, have characteristics and properties inherent only to them. In modeling, it is proposed to use a systematic approach to optimize the parameters. The principle of a systematic approach is considered. An example of dividing ABRM into subsystems is given. The graph of the simplified thermal circuit of ABRM is presented. Recommendations are given for optimizing the operating parameters.
