1. Introduction:
The climate chamber of heat – cold – humidity (hereinafter referred to as the climate chamber) is intended for carrying out climatic tests of photovoltaic modules. The climatic chamber will be operated under the following conditions:
– Ambient air temperature, °C: +15 … +30;
– Relative air humidity,%: 45 … 80;
– Atmospheric pressure: 84.0 … 106.7 kPa (630 … 800 mm Hg).
