    Assuming the coil area is round (which is unlikely because of non-uniform layering), the engineer may square the diameter for a more conservative estimated coil area. If applicable, that estimated coil area is then multiplied by the number of coils per slot. Total area of magnet wire: Calculate area of one wire, including

    Designing For Efficient Heat Transfer -

    The objective in all pattern designs is to maximize the heat transfer capacity while meeting the requirement for a low air pressure drop. Of course, efficient heat transfer through the coils results in higher energy efficiency for the system because the refrigerant cools down faster in the condenser and heats up faster in the

    N-shaped coils get much better results, however, because they allow for more overall coil surface area inside the unit, allowing them to accommodate more refrigerant and absorb or release more heat — without requiring larger equipment. Slab coils, while less common than the other two types, generally consist of coils that are in a straight
