Entering the Autumn, we are leaving at our back a very sweltering summer 2024. The past one has been indeed a very hot summer season, and this extremely hot weather involved a series of critical situations for refrigerating groups and conditioning systems.

Looking more in detail at the reasons of these critical situations, firstly one would easily say, well the weather has been very hot. But refrigerating groups and conditioning systems are employed exactly when the weather is hot. The problem is that usually these refrigerating and conditioning plants are designed considering an ambient temperature for condensation of about 35° C. During the last summer, the temperature raised very often above 35° C. With peaks of 38°, 40° or even 42° C, and a very high relative humidity rate. This led to very high condensation temperatures, and thus high condensation pressures.

Machines that were not designed for such ‘tropical’ conditions, so extreme, did undergo a failure, and got blocked: blocked refrigerating groups and conditioning systems, cooling systems for industrial production in down. Clearly, if the cooling systems go down on a conditioning plant, well, there is a discomfort for people due to the heat, but not entailing a great damage.

Instead, when this happens on industrial refrigeration groups that serve industrial production processes, the problem is way more relevant. And in fact, upon request of our customers, in Tempco we are re-designing cooling systems engineered considering higher ambient temperatures. Therefore we are starting sizing refrigerating groups intended for project ambient temperatures of 40° C, aiming at ensuring the required proper working efficiency in the future. That is, if we’ll have again further summer seasons so sweltering and hot, for sure these refrigerating groups will be able to keep on functioning, ensuring the required availability.
