| Abstract:
The performance and energy consumption of two infrared heating systems has been compared to traditional hot water pipe heating systems. Air temperature gradients appeared to be within an acceptable range under infrared. The nett heat consumption with infrared was about 12% lower compared to overhead heating pipes and was 6% lower when compared to a crop heating system combined with overhead pipes. The distribution of the radiation intensity showed to be very uneven. With the cultivation of tulips this resulted in differences in matureness. | |
