The Heating System Capacity Calculation of the Cultivation Facilities

Abstract

The article is devoted to the heating system capacity calculation of the cultivation facility, based on the conditions for ensuring the microclimate parameters regulated by the standards of technological design, depending on the external climatic conditions and the facility design parameters. One of the distinguishing features of the heating system capacity calculation of greenhouses is that the heat balance equation of the structure must be considered together with the equations of heat and mass transfer on the soil and covering constructions. The calculation is made for the greenhouse block № 3 in The Greenhouse Complex with a production area about 12 ha in the village of Sadovy, Ordzhonikidze District, Ekaterinburg. It takes into account convective and radiant heat exchange between the soil and the covering constructions, heat and mass exchange during evaporation and condensation and heat loss for heating infiltrating air. © Published under licence by IOP Publishing Ltd.
