NATURAL RESEARCH OF PARAMETERS MICROCLIMATE DOME GREENHOUSE NBG NAME'S M.M. GRISHKO NAS OF UKRAINE
This work is devoted to a comprehensive research of the microclimatic parameters of the dome greenhouse "Rainforest" NBG name's M. M. Grishko in order to organize effective natural ventilation (aeration) of the greenhouse during the warm season of the year. The research was carried out in several stages. At the first stage, measurements of temperature and humidity in the dome greenhouse were performed. At the second stage, natural researches of temperature and air velocity in the air intake mine of the dome greenhouse in the summer period were carried out. The data were obtained on the temperature, humidity, air velocity in the dome greenhouse during the year, as well as in the air intake shaft of the dome greenhouse in the summer period of the year. The analysis of the obtained data and the dynamics of changes in these parameters is performed. The results of the analysis are presented in graphical form. On the basis of the obtained data of natural researches, aeration of the dome greenhouse of NBG name's M. M. Grishko was calculated for three cases: 1. Under the influence of the pressure difference between the external and the internal air; 2. Under the influence of wind (wind aeration); 3. With the simultaneous influence of the pressure difference between the external air and the internal air and the influence of the wind. The areas of supply and exhaust ventilation openings, speed and air flow through them were obtained. The scheme of placement of ventilation openings is proposed to provide efficient aeration of the dome greenhouse of the NBG name's M. M. Grishko. The organization of effective aeration of the dome greenhouse will allow creating more favorable microclimatic conditions for tropical plants in the warm season. Ref.5, tabl. 10, fig. 4.
