Abstract: A base member includes a substantially horizontal main body that supports one or more components of a heating and cooling unit. The main body includes a conditioned space portion about a first side of the main body and a non-conditional space portion about a second side of the main body. A substantially vertical separation wall extends up from the main body and separates the conditioned space portion from the non-conditioned space portion. A lip is formed at least partially about the non-conditioned space portion. At least one drainage hole extends through the non-conditioned space portion. A surface of the non-conditioned space portion is sloped towards the at least one drainage hole. A drain pan is disposed about the conditioned space portion. At least one drainage tube is in fluid communication with the drain pan. A surface of the drain pan is sloped towards the at least one drainage tube.

Abstract: A heating ventilating and cooling (HVAC) system includes an outdoor air chase having a first end and a second end. The second end of the outdoor air chase is fluidly coupled to a condenser compartment at a location to receive outside air from the condenser compartment and the first end is fluidly coupled to the return air compartment. The outdoor air chase has a conduit through the outdoor air chase. The system includes a configurable flow regulating plate disposed in the outdoor air chase member across the conduit or otherwise across the outdoor airflow that has a plurality of discharge apertures. Initially, the plurality of discharge apertures is covered by a plurality of knockout panels. Each panel is removably secured to the plate. In installation, the installer removes as many of the knockout panels as required for a desired flow of outdoor air. Other systems and methods are presented.

Abstract: A distributor assembly for a space conditioning system comprising a sealed expansion device and a sealed distributor housing. The expansion device has a first opening, a second opening and an interior chamber there-between. The interior chamber contains an orifice housing, wherein the orifice housing has a through-hole orifice therein. The orifice housing is configured to move between the first opening and the second opening within the interior chamber. An outer surface of the orifice housing forms a fluid stop around the first opening such that a refrigeration fluid of the space conditioning system delivered through the second opening can substantially only pass through the through-hole orifice to the first opening. The distributor housing has a largest opening that is permanently sealed to the first opening of the sealed expansion device and a plurality of smaller openings configured to be fluidly connected to a heat-exchange coil of the space conditioning system.

Abstract: A system and method is described for a heater box or compartment within a gas furnace or other HVAC cabinet. The compartment can house drain hoses, drain traps, and other components used to collect and dispose of condensate. The compartment can comprise heating elements or thermostatic switches to assist in preventing the freezing of condensate.

Abstract: A condensation trap comprising an inlet chamber configured to receive condensate liquid through a receiving opening therein. The trap also comprises an internal chamber in fluid communication with the inlet chamber via a first internal opening defined by a sidewall shared by the inlet chamber and the internal chamber, the first internal opening located at an opposite end of the inlet chamber from the receiving opening. The trap also comprises an outlet chamber in fluid communication with the internal chamber via a second internal opening located at an opposite end of the internal chamber from the first internal opening. The trap also comprises a bleed orifice located in a sidewall shared by the internal chamber and the outlet chamber, wherein at least a portion of the bleed orifice is lateral to first internal opening.

Abstract: A heating and cooling unit (as well as individual components of the heating and cooling unit) is disclosed herein. Methods of installing and using the heating and cooling unit are also disclosed. The heating and cooling unit may include, among other things, a base member, a tube chase, a convertible drain, a system for mounting a burner box in a sideways orientation to a vestibule panel, a system for removably attaching a control panel to a collector box, a compressor supply plug, or a combination thereof.
