Movers, Refrigeration and Auxiliary Machinery


Basics of performance and modes of operation of the following systems:

• Types, designs, structures and operation of compactors (pumps and pumps, fans, blowers, compressors, filters). Piping systems for the flow of liquids and gases (water, seawater, fuels, lubricants, refrigeration, air, CO2, etc.); performance components, regulations that concern these systems and the basis for designing, operating and maintenance.

• Drinking water treatment plants (thin drinking water, hydrophoresis, evaporators, reversible osmosis plants and disinfection).

• Heat exchangers,

• Cooling devices, use of cooling devices, theoretical operating principles, left cooling circuits, refrigerant and their properties. Components of cooling devices, their performance and operation. Devices for monitoring and regulation. Maintenance of cooling devices. Operational disorders, cause detection and rectification, insulation of refrigerated spaces, defrosting, guidelines for determining capacity and for the selection of refrigerating appliances and operation and maintenance.


• Ventilation, the need for ventilation of work and living spaces, natural and mechanical ventilation, guidelines for determining the capacities and selection of ventilation devices, measurement of efficiency.

•          The heating. Performances of heating of working and living spaces. Guidelines for determining the required capacity and for the selection of cooling or heating devices.

• Air conditioning. The concept of air conditioning: regulating and monitoring the temperature, relative humidity, and the speed of air movement in the rooms. Systems for air conditioning of work and living spaces. Air conditioners with components, their design and function. Guidelines for determining the required capacity and for the selection of air conditioners and operation and maintenance.

• Hydraulic and pneumatic systems


- Routine-general on the management of pipeline systems,

- Management of bilge, ballast and transhipment piping systems.

• Purification, degrading and environmental protection devices (filters and separators, waste oil and faeces collectors, incinerators).

Characteristics of left circular cooling circuits, their improvement and influence on the cooling number and multi-stage cooling circuits. Theoretical and real cooling circuits with analyzes of irreversibility in the system.

Goals and competencies

Students should study theoretical basics of working machines, piping systems, ventilation, heating and air conditioning systems. They will learn about typical implementations of these machines and devices, their operation, maintenance and elimination of operational disruptions and preparations for starting individual devices and the entire system. They should be acquainted with the regulations concerning selection, installation and maintenance of these machines and devices.

Special Features:

Implementation of the learning content among others include requirements in accordance with the provisions of the STCW Convention A-III / 1, A-III / 2 and the recommendations of the "Chief engineer officer and second engineer officer (Model course 7.02)" and "Officer and charge of an engineering watch (model course 7.04) "International Maritime Organization, London, 2014
