Air handler and method for assembling a fan module

摘要

An air handler and a method of assembling a fan module are provided, in which a case panel may be assembled with a plurality of module frames via a considerably simplified sliding coupling providing excellent hermetic sealing. As such, manufacturing costs may be reduced due to reduction in a number of components, and assembly time may be remarkably reduced due to a reduced number of assembly operations. This advantageously results in reduced labor cost and enhanced air conditioning efficiency.
