Légkörmelegítés

Légkörmelegítés, a Hungarian term, translates to "air warming" and refers to a technique used in certain agricultural and horticultural contexts. Primarily, it involves the deliberate warming of the air within enclosed spaces such as greenhouses or polytunnels. The goal is to create a more favorable microclimate for plant growth, especially for sensitive crops or during colder seasons.

This practice aims to raise the ambient temperature above what would naturally occur, thereby extending the growing season, enabling the cultivation of non-native species, or accelerating crop development. Various methods can be employed for légkörmelegítés, ranging from simple passive solar gain through transparent coverings to active heating systems utilizing fuels like natural gas, propane, or electricity. The specific approach chosen often depends on economic factors, the scale of the operation, and the desired temperature differential.

Légkörmelegítés can have significant implications for energy consumption and environmental impact. While it can boost productivity and yield, the energy required for active heating can be substantial. Therefore, efficient insulation, heat recovery systems, and the strategic use of renewable energy sources are often considered to mitigate these concerns. The economic viability of légkörmelegítés is closely tied to the market value of the crops being cultivated and the cost of energy. It is a technique employed to gain a competitive advantage by controlling environmental conditions.
