Coolingsystem<br />- ±15°C (zones)<br />- Air circulation, insulation PU<br /><ul><li>Compressor, expansion valve, refrigerant, exchanging pipes</li></li></ul><li>Coolingsystem<br />1. Compression of Freon: high-pressure hot gas2. Condensation into liquid, dissipation of heat3. Expansion valve controls amount of freon to evaporate into low-pressure cold gas4. Warmth absorption, back to compressor<br />ventilation<br />circulation<br />
