The so-called comfort zone for air conditioning is between 20 and 26 °C and a humidity level of between 30 and 60%.
Did you know? Air conditioning systems have been proven to increase productivity and performance. Modern cars can no longer work without air conditioning. However, they are also used in office and administrative buildings, in the medical sector, in industry, and increasingly in residential buildings.
Colloquially, air conditioning is often understood to mean only room air cooling. However, this is not entirely correct. Air conditioning is a technical system for generating and maintaining a defined indoor air quality. It influences temperature, humidity, and CO2 concentration. The so-called comfort zone is between 20 and 26 °C and a humidity of between 30 and 60%.
Are the millions of air conditioning systems around the world sustainable from a resource conservation perspective?
Yes, if natural refrigerants and renewable electricity can be used in the manufacturing and operating phases, then there are no environmental or climate protection reasons to argue against the use of air conditioning systems.
The ILK Dresden is a sought-after partner for indoor air measurements, flow measurements, and the design of air conditioning and ventilation systems in many large-scale projects. The recently opened Humboldt Forum in Berlin's City Palace benefited from the expertise of our scientists and engineers. The air conditioning system sends approximately 50,000 m³ of supply air per hour to the forum's event center alone.
The Air Conditioning Dilemma: A Cool Home, a Warming Planet (in German):
Podcast Deutschlandfunk Kultur“Coop UP” – Implementing the Paris Agreement through sustainable refrigeration technology - ILK Dresden serves as technical advisor
Due to climate change, rapid population growth, urbanization, and rising living standards, energy demand in the Middle East and North Africa is projected to increase by 50% by 2040. Cooling accounts for a major portion of this energy demand, and inefficient cooling equipment that uses refrigerants with high global warming potential is often employed. The project supports the technological transition to reduce cooling demand and accelerate the implementation of the Kigali Amendment and the Paris Agreement in the partner countries. The approach is based on four pillars: reducing cooling demand, supporting the phase-out of hydrofluorocarbons, replacing and disposing of inefficient refrigeration equipment and refrigerants, and providing training and raising awareness. The project aims to catalyze long-term changes in the refrigeration and air-conditioning sector and ultimately strengthen the development of sustainable cooling technology in the market.
