ЭНЕРГОЭФФЕКТИВНОЕ ОСВЕЩЕНИЕ ДЛЯ ВЫРАЩИВАНИЯ МИКРОЗЕЛЕНИ НА ВЕРТИКАЛЬНЫХ ФЕРМАХ

Abstract

Vertical farms are a new approach to growing vegetables and berries, caused by the development of lighting technology and digitalization of technological processes. In Russia, the vertical farm market is just beginning to develop. The issue of high cost of manufactured products remains relevant. The cost of production is 1.3-1.5 times higher than the market average. This is due to the high costs of energy resources, primarily electricity. The main share of electricity is accounted for by lighting systems (80-90 percent). (Research purpose) The research purpose is creating the next generation of dynamic engineering systems, primarily lighting systems for vertical farms with intelligent control based on a differentiated day-to-day electricity tariff using digital technologies. (Materials and methods) Conducted production tests of dynamic lighting control methods at one of the sites of the ReTEK company, which made it possible to identify a more advanced and energy-efficient technology for controlling the vertical farm lighting system. The studies were carried out indoors without access to natural light, the air temperature during the production tests was 20-23 degrees Celsius with a relative humidity of 60-70 percent. (Results and discussion) It was found that the fresh weight of microgreening plants under experimental light was 18.5 percent higher than under control. It was determined that the cost of electricity consumed per 1 kilogram of micro-green under experimental light turned out to be 55.4 percent lower than under control. (Conclusions) It has been shown that the creation of the next generation of dynamic engineering systems, primarily lighting systems for vertical farms with intelligent control based on a differentiated day-to-day electricity tariff using digital technologies can significantly reduce energy costs and, as a result, reduce the cost of agricultural production.
