There are basically two types of air handling unit that are in used and they are the "Draw-Through" or "Blow-Through". In the Draw-Through type, the fan pulls the air through the mixing box, filters and cooling coil before discharging it from the fan outlet to the space to be conditioned or to the ducting network. The design can be vertical or horizontal. In this case, the section before the fan has negative pressure. In the Blow-Through type, the fan blows the air through the mixing box, filters and cooling coil before discharging them to the space being conditioned or the ducting system.
Q1 What is the Unit of Heat? Types of Heat:Sensible Heat: It can be sensed or measured by an ordinary dry bulb thermometer.

The direct expansion system in HVAC has been growing rapidly due to its ability to get rid of most duct work and piping. The popularity of this system is because the installation work has been made easier hence reducing the cost of the overall system. The DX System works in such a way that the evaporator is located in the space to be refrigerated. When the refrigerant in the evaporator coil expanded, it will cool the space by absorbing the heat from it. The mini splits , window air conditioner and packaged units are examples of such system. The diagram above shows a cooling cycle of a heat pump DX system. The valve used is a reversing valve that reverses the refrigerant flow to enable the heat pump to run cooling or heating.
