The efficiency of the heat pump included in the greenhouse heating system
Original language description
Objects with the horticultural production have a specific heat demand that is mostly dependent on the solar conditions. With low outdoor temperatures but high solar radiation intensity a large heat surpluses in greenhouses are generated. They are released into the atmosphere through ventilation system (Rutkowski, Wojciech, 2009). Simultaneously, if the gardening production is carried on there is a high heat demand for process water heating. Therefore, the goal of the study was to measure and exploit heat excess directly in the production process. To better use the heat surpluses the heat pump was integrated into the recovery system. Inclusion a heat pump into the system allows wider use of the effect, which is higher water temperature. Water with a higher temperature after mixing can be used for fertigation or as a heat accumulator in the greenhouse heating process. An adequate heat pump power, a matched buffer tank capacity and the way of use the energy stream from ventilation system
