Central Refrigeration Centre COCH in Kraków Sp. z o.o. hosted a group of 24 students from the Tadeusz Kościuszko Energy and Electronics Technical School No. 9 in Kraków. The visit, also attended by a physics teacher, included practical workshops and presentations related to refrigeration technologies.
The programme focused on practical topics linking theory with application. Activities included:
- Hard soldering/brazing – students made soldered joints and checked their tightness.
- Testing of refrigeration equipment and heat pumps – diagnostic methods and applications, including refrigerated furniture testing.
- Acoustic tests in an anechoic chamber – methods of analysing noise generated by refrigeration equipment.
- Experiments with dry ice – sublimation of dry ice and its applications.
- Effect of pressure on boiling temperature – experiments illustrating how pressure changes liquid properties.
During the workshops students learned methods and technologies used in refrigeration and asked questions on topics such as acoustic testing and noise reduction.
COCH management provided refreshments and comfortable conditions during the visit. The entire event was fully funded by the Centre, allowing students to take part at no extra cost.
The event was an opportunity for hands-on insight into refrigeration technologies and a valuable element of technical education support. Similar initiatives are planned for the future.
