Cool down the Global Warming
For years Teknotherm has been focusing on environmentally friendly installations meeting national and international regulations and standards as well as the classification society’s requirements for environmental notations.
Considering the global warming issue and its escalating dimension, Teknotherm desires to extend future solutions far beyond the requirements of todays rules and regulations in order to design the most environmentally friendly refrigeration and HVAC installations in order to make a difference to our environment.
The focus to obtain an environmental friendly refrigeration system can be divided into two main categories: – Choice of correct working medium known as the refrigerant, and secondly; – the design of the unit. Both these issues are important though the second is vital in obtaining an efficient, reliable and environmental friendly installation.
The refrigerants can be divided into two major groups. The artificial mediums commonly known as the HFCs contribute zero ozone depletion and varying greenhouse warming effect, while the other group known as the natural refrigerants contribute zero ozone depletion and very low warming effect.
Through correct design of the unit the amount of refrigerant required is reduced to a minimum, in order to ensure trouble-free operation. The correct medium for a specific unit contributes to optimizing the COP value, which indicates the efficiency of the unit; obtaining as many cooling effect kW as possible out of a minimal energy input. This energy is normally created via a combustion generator, and the reduction of the refrigeration unit’s energy requirements consequently reduce the the machine’s release of CO² into the atmosphere.
Arranging the refrigeration installation as an indirect system results in a reduction of filling, and a minimized number of joints, seals and valves as compared to a direct expansion system. This reduces the risk of leakage in the refrigerant medium.
Depending on the operation and sailing conditions of a vessel, natural cooling or so-called free cooling by use of ambient low temperature conditions can contribute to reducing the running time for a unit, resulting in substantially reduced overall CO2 emissions by the installation.
Teknotherm is consistantly working with these factors in order to contribute to a better environment, and will always be willing to advise on the subject of the correct design of your particular unit.
Saving the environment through the choice of the correct design and a reliable refrigeration system from Teknotherm will at the same time save your money.
