In the 35th episode, we covered:
- why copper is not actually getting cheaper;
- how AI redid as-built documentation 10 times faster than a construction documentation engineer;
- why the European Union needs a pan-European plan to fight heat.
We also discussed:
- a tragic refrigerant leak in Busan;
- a Mitsubishi Electric plate heat exchanger that is three times more efficient than a conventional one;
- a Clivet magnetic-levitation compressor;
- new IEC limits for A2 and A3 refrigerant charges.
We also talked separately about our market 🛒
- In the “Cheapest split system of the week” segment on Wildberries, Vickers still leads at 9–10 thousand rubles, and “Biryusa” has reappeared on Ozon.
- “Chestny Znak” is now being integrated with the SPOT import control system, and we ask viewers: will labeling reach residential air conditioners by the 2027 season?
The guest of the episode is Vitaliy Ryauzov, an HVAC technician from Prague.
In Czechia, the summer turned out to be abnormally hot, and sales increased several-fold: Vitaliy had about 50 requests per day without any advertising. He explained:
- why they install Toshiba with A+++ for heating rather than Chinese brands;
- which air conditioner is the quietest;
- why designers in Revit are now paid like IT specialists.
The most interesting part of the conversation is energy ⚡️
In Czechia, the electricity price changes every 15 minutes and is known a day in advance. A smart controller sells energy from a home battery during peak hours, an electric car becomes a battery for the home, and surplus from a solar plant can be sent to the grid as a “virtual battery” or transferred to relatives.
At the end — Midea on R290 with a built-in propane leak detector.
