Our focal point in cooling technology is the topic “The future of sustainable cooling systems.” Practically every technical system in the most diverse areas of application, e.g., terminals at the port, data centers, building services engineering, etc., has an air conditioning unit integrated or installed. Air conditioning systems are responsible for a significant part of the worldwide Carbon dioxide (CO2) emissions and energy consumption.
Basic Principle of a Sustainable Cooling System
Today, I am working on the topic “The future of sustainable cooling systems” in the terminal area of ports and other areas of application, e.g., the cooling of data centers. My inspiration for natural sciences (mathematics, physics, and chemistry) starts during my school days in Kenya.
“The basic principle of the “Heat Exchanger System” (HES) is: “Warm air rises to the top and cold air falls to the bottom” and this principle is implemented in the “Heat Exchanger Unit” (HEU as a subcomponent of the HES).”
Mr. Horst Schneider
Sustainability in cooling systems could greatly contribute to reducing CO2 emissions, increasing efficiency, and improving operational safety in all application areas.
From a technical, ecological, and economic point of view, what problems should a cooling system in an electrical switchgear building resolve?
The general conditions inside and outside of the electrical switchgear building (e.g., weather, movement by crane, etc.) influence the cooling capacity required for heat discharge (output) and the energy required for heat removal (input). From a technical point of view, heat extraction should guarantee the highest possible operational safety. This should be done so that, from an ecological and economic point of view, the lowest possible heat extraction costs are incurred. Operational safety at the terminal means the crane is always ready for operation and can carry out its activities without disturbance. The costs of heat removal are subject to the opportunity principle when selecting alternative heat removal options.
Which goal do terminal operators pursue when optimizing cooling systems on water-side cranes and automated stacking cranes?
Terminal operators as end-users of the Heat Exchanger System achieve higher operational safety while optimizing the energy consumption for heat dissipation from summer to winter, day and night, in the electrical switch house for the automated cranes. Teamwork between the various stakeholders significantly contributes to achieving the terminal operator’s goals. The various stakeholders in the implementation of the HES in the Port of Hamburg (CTB) are HHLA Hamburg and HCCR Hamburg, ABB Cranes System Västerås, Sweden, Elektrotechnik Janssen GmbH, Nordenham, KÜNZ GmbH Hard, Austria, Kampmann Gruppe/NOVA Donaueschingen, Reiss Kälte und Klima Freiburg im Breisgau.
How important are sustainability and climate neutrality for terminals?
“HHLA’s goal: a climate-neutral company by 2040” is the corporate strategy of Hamburger Hafen und Logistik (HHLA) AG on sustainability. HHLA’s sustainability strategy is managed under the “Balanced Logistics” brand, says Chief Executive Officer Ms Titzrath. Another example of how climate neutrality and sustainability are essential for terminals worldwide is shown by AMPT’s Maasvlakte II terminal in Rotterdam, Netherlands, where the Heat-Exchanger-System (HES) is integrated into all fully automated stacking cranes and rail loading cranes. HHLA justifies its sustainability orientation by wanting to be economically successful in its business fields and assume social and ecological responsibility. This also means that HHLA intends to create a balance between economic and environmental efficiency.
