New approach to integrate PV-powered heat pumps into greenhouses

Scientists have proposed to use PV energy and heat pump-driven HVAC system in greenhouses conceived to grow tomatoes in the Mediterranean area. The system was found to have a payback time of only 2.9 years in southern Spain.Researchers from Turkey and Qatar have simulated the growth of tomatoes in a greenhouse equipped with a heating, ventilation, and air conditioning (HVAC) system powered by PV panels and an air-source heat pump. The group developed a novel numerical simulation model that can account for plant growth and evaporation. "It is more challenging to keep the greenhouse's indoor environment ...
