Modeling of solar and heat pump energy supply systems for autonomous greenhouses

The article presents the results of determining the heat load of a even-span greenhouse with a usable area of ​​​​50 m2 in variable climatic conditions, modeling the heating system of an autonomous greenhouse based on solar and heat pump devices. The modeling was performed taking into account the ambient temperature, solar radiation and heat losses in the greenhouse for the period from November 15, 2023 to March 15, 2024. According to the results, it was studied that the greenhouse consumed 14720 kWh of heat energy during this season. Of this, 11135 kWh of heat energy was provided by a heat pump, 2225 kWh by a solar thermal collector, 100 kWh by a heat boiler, and the rest by solar radiation.
