Solar-Radiative Heating of Different Objects in the Regions with Severe Climatic Conditions
RÉSUMÉ
A number of experiments were carried out in the Middle Urals and the permafrost zones in Mongolia. The temperature regimes of a house with a solar air heater were studied. In winter, the air temperature indoors is up to +20°C in the daytime, while the temperature outside is –1°C. The economy of energy resources in winter was near 10–15% and in spring and autumn was equal to 35%. The solar heating of a greenhouse gives economy of 60–80% if it is used for nine months per year, which allows one to get two crops during one year even under permanent frost conditions. In testing a solar concentrator, the heat receiver temperature was obtained to be 340°C. A flat solar collector (S = 1–2 m) can heat 300 liters of cold (8°C) water up to 30–60°C in 24 h in the Middle Urals climate in the spring–summer–autumn period.
