| Abstract:
The basic equations of a computermodel, simulating the greenhouse heating requirements, are presented. One of the possible outcomes of this model, the cumulative frequency distribution curve, is discussed. The influence of some energysaving measures on the curves is shown. The significance of the curves as an aid in designing greenhouse heating systems is illustrated in two examples concerning the utilisation of two different heat sources. | |
