Opis:
The paper presents and describes cooling systems mainly used in industrial plants specialized in production based on injection moulding machines. Each solution is rated taking into account investment costs, technical complexity, exploitation costs and system flexibility in general. With regard to dynamically changing law regulations linked to refrigeration installations, mainly F-Gases Act, during optimal system selection new restrictions were respected. This approach ensures long-term exploitation without additional complications. The paper contains characteristics of cooled facility, i.e. production plastic plant using injection moulding machines, presents specifics for this type of application where two extremely different cooling processes are placed in parallel. One task is heat collection from injection moulds to ensure short production time and produced details recurrence, the second is keeping hydraulic oil temperature between temperature limits – this process ensures proper oil viscosity and prevents its premature wear.

Opis:
The frequent causes of ships’ detentions by port authorities are abnormalities of marine power plant functioning. Each extended ship lay time in port results in a waste of ship operating time thus costs rise to ship owners. This is connected with improper marine power plant management. In order to avoid this, a ship engineer should have at his disposal computer aided system supporting him in the managing of the marine power plant. One element of the decision making process in managing the marine engine room is to determine how important is each of the tasks which the operators have to do. This estimation is the base to choose the most important tasks and make optimal schedule with them using AHP method. Based on practice, a hierarchic structure of factors influencing a tasks validity in the engine room operating process was made. Next a preliminary questionnaire was conducted, which put questions to the experts as chief engineers next. This enabled to define numerical values of suitable coefficients influencing on the validity of operating tasks, show results of calculations in form of mileage parameters of engine as a function of crank angle.
