FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular to greenhouses with night heating of soil with soil heat exchangers with liquid-heat carrier, heated in solar collector. Greenhouse comprises a translucent protective canopy 1, a heat accumulator, electric heater 10, temperature sensors, a ground heat exchanger and pumps which circulate liquid-heat carrier. Heat accumulator is installed in greenhouse under dome at the top in zone of maximum heating of greenhouse and consists of tanks 2 interconnected by pipelines, wherein ground heat exchanger is made in the form of sections of flexible coaxial hose 7.
EFFECT: device allows maintaining the preset temperature in the greenhouse uniformly over the entire area at night, simplifies the design and reduces the cost of production owing to the absence of a separate solar collector, and facilitates ease of installation and dismantling.
