A blower coil is a type of air handling unit that is used to condition air in a variety of settings. It is a combination of a fan, a coil, and a filter, all of which work together to deliver conditioned air to a space. The fan draws in air from the outside and passes it through the coil, which is filled with refrigerant. The refrigerant absorbs heat from the air, cooling it down, and then the cooled air is passed through the filter before being released into the space. The blower coil is an efficient way to cool a space, as it is able to cool the air quickly and efficiently. It is also a cost-effective option, as it requires less energy to operate than other air conditioning systems. Blower coils are used in a variety of settings, from commercial buildings to residential homes, and they are an essential part of any air conditioning system.
