Maintenance Management of Engineering Assets Assignment

Maintenance Management of Engineering Assets - Assignment Example Evaporative air conditioners are usually composed of two main units which are the condenser and the evaporator. The condenser is normally situated outside the room preferably on a concrete slab while the evaporator is usually mounted on the duct of the main junction on top of the furnace (Wasim et al, 2009). Most of the central air conditioners are normally linked to the forced air distribution systems for houses and thus both systems share the same motors and blowers. Both units of the central air conditioner are usually sealed. The evaporative condenser works on a basic principle that if air flows past water, it will cause it to evaporate. In an evaporative air conditioner, hot air usually enters the cooling unit situated on the roof of the building whereby it is filtered and then cooled as it goes through special pads that are moistened for this task. This unit is normally referred to as the condenser. The moistened air is then directed to the evaporator which is composed of ventilator and a fan. The fan blows smoothly through the cooled air distributing it through the house (Wasim et al, 2009). The hot air in that is present in the house is then forced out of the room through the windows and the ventilators resulting in a total shift in the air present in the room. By controlling the speed of the fan, the air temperatures can be controlled. The evaporative air conditioner requires water and hence a constant supply of water must be present. This unit I composed of the wet pads and the water tank. The water tank holds water that is used to cool the pads. The water held in the tank must be constantly supplied to the system in such that the warm water flows out allowing for a fresh supply of water to flow in. The wet pads are usually composed of either corrugated paper with a binder or wood wool. However, corrugated paper with binder is preferred over the wood wool since it lasts longer and the
