IV. HEAT LOAD OF POULTRY INCUBATORI

IV. HEAT LOAD OF POULTRY INCUBATOR
In determining the heat load of the PV poultry egg
incubator, the following assumptions were made: steady state
condition exists, one dimensional heat flow prevails,
incubator materials have constant thermal conductivity, and
the incubator is a closed system at constant temperature.
Table I shows the wet bulb reading at various incubator
temperatures.
The heat balance equation of the incubator chamber [4] was
estimated by
Qload = Qpv + Qegg – Qcnd – Qcnv
Qload = Heat load of the incubator, W
Qpv = Heat supplied by PV panels, W
Qegg = Heat supplies due to metabolic actions of egg, W
Qcnd = Heat loss by conduction through incubator walls
Qcnv = Heat loss through air convection
