We call our new innovative solution “MESLED” (Multifunctional Energy System powered by a LED light & heat source). Its key component is a completely new multifunctional device – MESLED MODULE, able to adapt operation mode by actual season and farmer's needs. More mesled modules connected to the pipeline infrastructure create our true product – MESLED SYSTEM.
Each greenhouse is built only at place where groundwater for plants is available. The temperature of this water is around 12 °C in the summer. Mesled is able to use free underground cold to cool down both the growing space and the LED light sources in the summer season (DOUBLE-COOLING). The most efficient cooling process for any space is due to the thermal gravity to cool it from the top. Therefore, we invented a hybrid device consisting of a LED luminaire and convection heat exchanger. The interconnection of all THREE TECHNICAL SOURCES (light, air, heat/cold) into ONE MULTIFUNCTIONAL DEVICE opens the door to optimally use waste heat generated from semiconductor LED light sources.
Waste heat can be used to warm the system’s working water (preheating). Included fan in mesled modules can blow the waste heat down as a warm air. Warm air blown from the top of a greenhouse creates an active thermal barrier for radiant heat. The energy intensity of the winter season decreases when the heat is kept inside the greenhouse and does not leak (reduced radiant heat losses). We can achieve the needed homogeneity of this unique VIRTUAL HEAT INSULATION using many mesled modules for photosynthesis (mesled modules).
Mesled multifunctional system is able to adapt to the current season or in case if changes are needed. This universal and comprehensive mesled system maximizes the greenhouse energy efficiency in both cold and warm climate (in summer and winter season). The optimal form (warm air or water) of used waste heat from LEDs can be seasonally adapted thanks to three different operating modes of the new smart mesled module – a three-way circulated water within the modules (3 operation modes of mesled module/system).
A reliable, sustainable and long-life water-cooled LED lighting system supports the sustainable business of progressive farmers = SUSTAINABLE HEALTHY FOOD PRODUCTION. This multifunctionality is manifested in investment saving, simplified maintenance and installation and minimal daylight shading in greenhouses.
Based on our know-how we are ready to introduce a new multifunctional system, providing virtual heat insulation in winter, year-round lighting and air exchange, and double-cooling in summer (growing space and LEDs). This 3-IN-ONE solution converts each greenhouse into a year-round available electrical appliance in the grid, thus supporting the development of the electricity market via demand regulation.
