AAF HERMAN NELSON HEATING AND COOLING PARTS

Unit ventilators are particularly installed in rooms to ensure that good air quality is maintained. They provide sufficient ventilation by means of filtration and provision of thermal comfort. That is why the AAF-Herman Nelson heating and cooling part is a necessary component of the unit ventilator. The 4-pipe application is used in unit ventilators since it enables the automatic transformation according to room temperature.

Consequently it is essential to bear in mind that it is the primary function of the unit ventilator. In certain occasions the unit ventilator uses separate heating and cooling coils. Some of the popular heating and cooling parts include the 1 row, 2 row and 3 row hot water coils for heating. 2 row, 3 row and 4 row pipe coil for cooling.

Apart from that,it may also consist of a low capacity, high capacity, low electric, or high electric heat coil for the heating function. The cooling function on the other hand may consist of the 2, 3 or 4 row CW coil. It may also consist of the direct expansion coil which is necessary for cooling. These parts have to function hand in hand with one another so as to ensure that proper room temperature is maintained.

The necessity of the AAF-Herman Nelson heating and cooling part for the unit ventilator can be attributed to the fact that excess heat in rooms comes from uncontrolled heat sources. That is why the heat in the room has to be controlled and this can only be achieved by installing the heating and cooling parts in the unit ventilator. This will maintain the room temperature at considerable levels regardless of the intensity of heat coming from uncontrolled sources.
