Heater is a combination of fans, motors and air heaters combined unit. Applicable to all types of workshops, when the air is free of dust and flammable or explosive gas, can be used as a circulating air heating. Heater can be used independently as a heating, generally used to supplement the lack of heat sink parts or the use of radiators as the duty of heating, the remaining heat load borne by the heater.
(1) horizontal blower: indoor air from the side of the inhalation, the heat exchanger after the heat, the horizontal direction. The jet has a certain range, so that the heating zone is fully blended, the temperature is evenly mixed.
(2) top blower fan: axial fan placed in the bottom of the unit, the air from the side of the heater into the air through the standing heat exchanger, and then sent down. In order to make the jet face to be discharged downward, a guide vane for diffusion is provided at the outlet of the fan.
(3) floor heaters: such units of the large amount of air, send hot air range far, can afford a larger area of heating. When running, the noise is large. Applicable to the factory building heating.
The advantage of heater heating is [2]:
(1) single machine heat supply, in the same heat load, the number of end devices used less;
(2) small heaters can be hanging, do not take up the building area, large heaters floor installation, covers an area of limited;
(3) start heating up fast.
