Abstract EN
Infrared (IR) heating as alternative to forced air heating has been studied experimentally for 70 days in two identical, small-scale, experimental greenhouses.
The two heating options were implemented with four IR electric lamps and an electric forced air heater correspondingly.
The microclimate in the greenhouses was monitored with thermocouples.
Parameters characterizing the outdoors macroclimate were also monitored.
Lettuce was used as the test crop, and the two heating systems were operated automatically to maintain a suitable reference temperature at the canopy.
The investigation focused on night heating needs.
Results indicated that the internal air temperature in the IR-heated greenhouse was always kept several degrees lower than the value targeted for the canopy.
This lower temperature resulted in 43% average energy savings for the IR-heated greenhouse, compared to the conventionally heated one.
A simple numerical model was used to estimate the potential energy savings in a production-scale greenhouse.
