" A" Frame Evaporator Coil Air Handler Cooling Coil

An "A" Frame Evaporator Coil is a type of evaporator coil used in HVAC systems. It is named for its "A" - shaped structure, which consists of two slanted sides joined at the top.

The refrigerant tubes are attached to the interior of the A - shape. The tubes run back and forth, and you can see the looped refrigerant tubes exiting the coil and looping back in. The fins are usually made of copper or aluminum and are attached to the refrigerant tubes to increase the surface area for heat exchange.

The evaporator coil is a crucial component in the HVAC system. Its main function is to absorb heat from the air inside a building as the refrigerant evaporates within it. This process cools the air, which is then circulated throughout the space by the blower fan.

Advantages

Efficient heat exchange: The "A" shape maximizes the surface area for heat exchange within a compact space. This design allows for more efficient heat transfer between the refrigerant and the air, improving the overall performance of the HVAC system.

Space - saving: Due to its compact design, the A - frame evaporator coil is particularly suitable for residential air conditioning units where space is often limited. It can be installed in various locations, such as inside the air handler unit, on top of or near the furnace, or in the fan coil unit.

Moisture management: In AC mode, as the coil and refrigerant collect heat, the coil fins get very cold, and moisture naturally condenses on the coil. The A - shape allows the moisture to flow down and drip into a pan, which helps with moisture management and prevents water from accumulating in the wrong places.
