ABSTRACT:
A redundant, dual circuit air conditioning apparatus is provided for communications enclosures which is wall mounted thereon. A conditioned air housing is provided having a blower chamber which contains two air circulation blowers thrusting air into the enclosure and having freely pivotal ducts which operate in mutual cooperation in response to pressure variations between the chamber and the enclosure. Internested evaporator coils of two discrete refrigeration circuits share common fin connections for efficiency and each includes a dual line input performing in conjunction with an expansion valve and a simple Y distribution fitting coupled to those lines which achieves requisite pressure drops at low cost. Compressor and condenser components are located within a condenser system housing in mutual isolation and perform in conjunction with discrete separate power inputs and controls such that servicing may take place safely upon one air conditioning entity while the other remains in operation to prevent down time during servicing.
