Abstract
The primary task of a greenhouse is to create optimal microclimate, which doesn’t depend on external climatic conditions, to grow plants. We can observe significant air temperature and humidity difference in a traditional greenhouse during 24 hours. The stable microclimate in greenhouses is provided by different engineering systems such as heating, ventilation, lighting, etc. These systems require a lot of energy. Saving energy and reducing the mode of temperature amplitude inside the operating greenhouse during exploitation period can be achieved by using solar energy in the greenhouse heating system, namely, by using heat accumulators. However, the test method of optimal heat accumulator to equalize the temperature amplitude inside the greenhouse wasn’t described in any research. The purpose of this research is to determine the optimal heat accumulator for equalizing temperature amplitude inside the greenhouse under atmospheric effects in spring. The experimental research of the heat-humid regime was carried out for the greenhouse without any heat accumulation. Relationship between the volume and the surface area of the accumulator and its efficiency was identified.
