Climate chamber

The climatic chamber is designed for testing technical devices in various weather conditions including extreme heat and cold. Environmental conditions there are defined exactly, which allows to repeatedly compare behavior of the tested technical devices. The climatic tests can prove the endurance, reliability and functionality of these devices. The chamber allows to perform both stationary and transient climatic tests which simulate real weather conditions in complex way. Namely, it simulates the effect temperature, humidity and solar global radiation.

The Angelantoni climatic chamber allows to simulate diverse weather conditions typical for polar, mild temperate, tropical or desert climates. The important part of the chamber is so-called artificial sun (mobile system of lamps) simulating solar radiation intensity and direction of “Sun” rays impacting onto the tested object. Other parts of chamber are a machine room with technologies for cooling, heating, humidification and dehumidification of air flowing in, suction system for combustion emission produced during car tests, CO₂ extinguishing systems combined with fire detection and control (PLC) system. The control system can handle with air temperature, relative humidity and intensity of global radiation from lamps.  The chamber dimensions and construction allows to perform climatic tests of separate cabins of transport vehicles and even cars with the running engine.
