20140039687 | FIELD CUSTOM FREQUENCY SKIPPING - A method, system, and control system for operating a HVAC system having one or more variable-speed components is provided. The method includes running the one or more variable-speed components at a first setpoint, and determining that the first setpoint generates a response having an intensity above a threshold. The response includes a vibration, a noise, or a combination thereof. The method further includes logging the first setpoint into a list of setpoints to avoid. The method also includes, in response to determining that the first setpoint generates the response having the intensity above the threshold, adjusting the one or more variable-speed components to a second setpoint. | 02-06-2014 |
20140099086 | APPLICATION OF ELECTRIC HEAT COIL IN FAN UNIT - An electric heat coil assembly for use adjacent a heat exchanger assembly in a fan coil unit is provided including at least one electric heat coil. A mount plate supports the at least one electric heat coil such that the at least one electric heat coil extends from the mount plate. The mount plate includes an edge configured to connect to the heat exchanger assembly. At least one relay is coupled to the at least one electric heat coil. The at least one relay selectively applies power to the electric heat coil. | 04-10-2014 |
20140332189 | FAN COIL UNIT - A fan coil unit is provided including a cabinet formed from a plurality of panels. A fan assembly is configured to circulate air through the cabinet. A heat exchanger assembly is positioned within the cabinet. The heat exchanger assembly includes at least one heat exchanger coil arranged in a heat transfer relationship with the air circulating through the cabinet. An inner surface of at least one of the plurality of panels is partially lined with an elastomeric foam insulation so that the air circulating through the cabinet does not contact the portion of the at least one panel lined with the elastomeric foam insulation. | 11-13-2014 |
20150034290 | AIR HANDLER WITH A LEAK FREE CONTROLS ENCLOSURE - An air handler configured with a second enclosure disposed within the first enclosure to create a continuous airflow passageway, wherein access to the second enclosure does not interrupt the continuous airflow passageway. | 02-05-2015 |
20150153064 | MULTI-POISE CONDENSATE DRAIN PAN - A condensate drain pan including an inner front wall, an inner back wall and opposed inner side walls defining an inner perimeter, at least one outer front wall, an outer back wall and opposed outer side walls defining an outer perimeter. The condensate drain pan further includes at least one drain pan panel extending between the inner perimeter and the outer perimeter, at least one drain opening disposed in the outer front wall, and at least one coil conduit aperture disposed in the outer front wall configured to allow at least one coil conduit to be inserted therethrough. | 06-04-2015 |
20150153094 | MULTI-POISE CONDENSATE DRAIN PAN - A condensate drain pan including an inner front wall, an inner back wall and opposed inner side walls defining an inner perimeter, at least two outer front walls, an outer back wall and opposed outer side walls defining an outer perimeter. The condensate drain pan further includes at least one drain pan panel extending between the inner perimeter and the outer perimeter, and at least one drain opening disposed in the outer front wall. | 06-04-2015 |
20150153095 | UPFLOW CONDENSATE DRAIN PAN - A condensate drain pan including a front wall, including a front wall longitudinal axis, a rear wall, and opposing side walls extending from a drain pan surface. The front wall includes a first aperture and a second aperture, including an aperture axis, wherein the aperture axis forms an angle less than 90 degrees with the front wall longitudinal axis. | 06-04-2015 |
20150153096 | UPFLOW CONDENSATE DRAIN PAN - A condensate drain pan including a drain pan panel, including a panel interior side and a panel exterior side, a channel member formed on the panel exterior side, a front wall, a rear wall, and opposing side walls. The front wall, rear wall and opposing side walls extend from the drain pan panel to form a receptacle, and the front wall includes a first aperture and a second aperture in the front wall. | 06-04-2015 |
20150153111 | INDOOR COIL - An indoor coil including at least one coil slab. The at least one coil slab including a pair of coil slab end surfaces extending between a pair coil slab faces, a coil slab axis, and a plurality of conduits, operably coupled to one another, disposed therein. One of the pair of coil slab end surfaces forms an angle greater than or equal to 45 degrees and less than 90 degrees with the coil slab axis, and the plurality of conduits are arranged in a staggered configuration. | 06-04-2015 |
