Refrigeration and air conditioning only for people from outside these industries are the same. In fact, the refrigerant circuit is identical, but the intended use, technical considerations, market size, power levels and business habits are as far apart as welding is from playing the piano.
Refrigeration works all year round. Air conditioning not anymore. This minor fact influences the profitability of energy saving solutions in a fundamental way. This is especially important for R744 systems, which operate in a subcritical – very, very economical and supercritical – moderately economical, above this value below an outside temperature of about 25 ° C. For obvious reasons, air conditioning requires coolness at high outdoor temperatures – those that require or are close to supercritical work. So what technically has to happen for CO2 chillers to be more widely used in air conditioning?
I present my opinion:
This, of course, is only part of the puzzle required to popularize the R744 in air conditioning. Meanwhile, after such a short introduction, I invite you to read the notes in our section as well as the information and articles contained in this issue. It is worth knowing more.

It’s good when the refrigeration works – we can provide that and it doesn’t use a lot of energy unnecessarily – we’re really good at that. It’s probably not modest. Refrigeration is important to us. We believe… we know that a well-designed and executed cooling system in the plastics processing industry can make all the […]
Electric cars, photovoltaics, heat pumps – these are topics that, in the broadly understood utility of consciousness, operate on a daily basis. Everyone has an opinion on them, including breakfast TV presenters and politicians. On two topics I will not stand out, but on heat pumps that I have the right and competence. Fortunately, one […]
A sailing ship needs wind to move towards its destination. The stronger it is, the faster the boat moves forward. However, when the wind is too strong, it jerks the sails and raises waves that can sink an entire ship. The situation of companies in our industry is similar. He laughs himself at how […]
