Necessary heat-capacity: Separately from a balanced ventilation/heating system, it is of course important how much installed heating/capacity you need in your livestock buildings. The need for heat is calculated as follows: ‘Transmission-loss + ventilation-loss = heating-capacity + animal-heat’’ The following points should be kept in mind: • Room compartment (weaner, farrow, breeding, gestation and broiler houses). • Compartment-temperature and minimum outside-temperature. • Wind velocity. • R-value (insulatingvalue) of walls, roof and floor. • Minimum ventilation-quantity. Climate: The ventilation systems are becoming more and more accurate all the time and the climate-control is continuously playing a bigger role. In general a modern: micro-climate system integrates ventilation, heating and cooling and is controlled between narrow margins. Demands: Using roof ventilation systems, or individual inlets or continuous inlets, it is known that the incoming air is departed through the inlets, through which the airspeed is very low (no draught symptoms). In order to warm this air, it is necessary to place under the ceiling heating-elements. Important for the heating system: • Need to be a good heat-conductor. • Need to have a high reaction-speed. • Have a great radiation. • Are light-weighted (7 kg per 20 ft, included the water). • Have a long lifetime. • Have a simple assembling and a good manage ability. • Without additional machining connectable after measuring correct length size. Great reaction speed: Due to the high heat radiation of the DELTA/TWIN tube and the small water-volume, one gets a very high reaction-speed which is very important. Long lifetime: The aluminium DELTA-tubes are anodised to prevent corrosion. Against external corrosion: aggressive climate, Against galvanic corrosion: only aluminium or plastic couplings.
