Kepko O. Grounds for energy-saving regimes of closed heating and ventilation system of greenhouse facilities

The objects of researches are the processes of warmth utilization and air regeneration in the closed heating and ventilation system of the hothouses mate as a complex of buildings "vegetable hothouses-mushroom hothouse". The aim of research is decreasing the consumption of thermal end electric energy in hothouses by application of the suggested closed heating end, ventilation system an the basis theoretical end experimental research of heat end gas interchange in the closed ventilation system. Research methods are theoretical end experimental studies according to standards methods. Theoretical and practical results are: determination of static and dynamic descriptions of hothouses on of temperature and СО2 channels in closed system; developed of closed system calculation method; working out of the theoretical principles of head and gas interchange automation in the system. Research novelty is in theoretical exploration and experimentally confirmation of parameters of heat and gas interchange processesin the hothouse heating and ventilation closed system. The use of the thermal pump in the system has been greenhouse. The research was introduction in Ukrainian Scientific Research Institute "Agroproject" of the ministry of Agrarian Policy of Ukraine in Kiev, Uman State Agrarian University of the ministry of Agrarian Policy of Ukraine. The sphere of use are hothouse farms, project establishments, technical educational establishments of the ІІІ-ІV levels of accreditation.
