The French-Polish Chamber of Commerce is an organization established in 1994, associating over 450 companies.
Such a number of members makes it one of the largest bilateral chambers in our country.
From now on, also SZE is part of it.
In this good company, we represent refrigeration, energy efficiency and ecology.
Our mission is to make the industry green by providing it with refrigeration that is economically and environmentally profitable. Which, with an appropriate scale of implementation, will give a better future to everyone.
La Chambre de Commerce Franco-Polonaise est une organisation fondée en 1994, associant plus de 450 entreprises.
Un tel nombre de membres en fait l’une des plus grandes chambres bilatérales de notre pays.
Désormais, la SZE en fait également partie.
Nous représentons la réfrigération, l’efficacité énergétique et l’écologie.
Notre mission est de rendre l’industrie respectueuse de l’environnement en fournissant une technologie de réfrigération rentable à la fois pour les entreprises et pour l’environnement. Ce qui, avec une échelle de mise en œuvre appropriée, donnera un avenir meilleur à chacun.
It is a device in an “air conditioner” type housing, which contains all the necessary elements such as:
complete refrigeration circuit
The use of an expansion valve inside the unit significantly simplifies the connection because it is no longer necessary to use it at the evaporator. It also simplifies control as all you need to do is use the thermostat and defrost heaters.
The unit does not have a refrigerant tank, thanks to which the amount of refrigerant in the installation is negligible (max 1.5 kg).
As an SZ, we support our clients in designing and commissioning installations based on SANDEN aggregates.
About CO2 refrigeration, but also about news and the future.
At the time when this department was created, the r744 technology was the most modern commercially available refrigeration solution. Therefore, I also think of it as an activity with the most interesting, state-of-the-art refrigeration technologies. About what lies ahead. That’s why this month I decided to take a look at the refrigeration eco-technologies of the future.
First, r718 – water. Chillers operating on water in the theoretically traditional closed circuit with evaporation and condensation are already available. The devices are offered in power up to 120 kW at temperatures from 10 to 28C. An interesting fact is that during start-up, the device can be filled with ordinary water from the network. The heart of the system is a rotary compressor, similar to a turbocharger in a car, with a maximum speed of up to 88,000 per minute! Considering the temperatures achieved, I can see the use of these chillers in server rooms, polymer production and all applications, let’s call it high temperature, where energy efficiency is important.
Second, Absorption. This technology should probably be listed first by me. Probably not necessary, but I will explain – we are talking about turning heat into cold. Of course, the great potential for this technology comes with cogeneration, thanks to which a stable source of heat with appropriate parameters is obtained. The second application – currently, unfortunately, still in the sphere of theory – can be obtaining cold, the source of which could be the municipal heating network. Unfortunately, in the summer, operators reduce heat parameters below the minimum values that could be used by absorption technology.
Third… technology developed at MIT, yet unnamed. We are talking about a material that prevents heating the interior of a room or chamber, and at the same time has the ability to transmit heat only in one direction – to the outside. This solution allows you to effectively cool the interior by about 13C. We look forward to combining this new coating with airgel insulating material.
