A frameless HVAC door system for reduced noise transmission leakage, and improved installation. The system includes a first member having opposed first and second surfaces and a first size that defines a first perimeter extending around the first and second surfaces. The first member is further equipped with a latch spaced apart from a hinge member on the first member. The door further includes a second member mounted on the first member first surface. The second member includes a sidewall extending around the second member to define a second member perimeter. The second member further includes a second member surface extending between the side walls and along the second member perimeter to define a compartment. The compartment is insulated against noise and temperature change. The second member perimeter is smaller than the first member perimeter, which defines a flange extending from the second member perimeter to the first member perimeter to define a flange perimeter. The flange is equipped with a resilient elastic foam sealing material along its perimeter. The first member is hingedly mounted to a surface around an opening for pivotal movement relative thereto. When the latch engages the latch receiver, it distributes a uniform compressive sealing force along the flange when the first member is in a closed position relative to the opening.
Methods for installing one or more heating, ventilation, and air conditioning (HVAC) units in an HVAC system include the steps of securing inlet and outlet piping assemblies of the HVAC unit to a bracket, coupling a thermal transfer mechanism of the HVAC unit with the inlet piping assembly and the outlet piping assembly, fluidly coupling a water pump with the thermal transfer mechanism, the inlet piping assembly, or the outlet piping assembly, mounting the HVAC unit by mounting the bracket to the HVAC system, and maintaining alignment of the HVAC unit thermal transfer mechanism, the HVAC unit inlet piping assembly, and the HVAC unit outlet piping assembly while mounting the HVAC unit in the HVAC system. An HVAC unit can include a thermal transfer mechanism, inlet and outlet piping assemblies, a water pump, and a bracket.
F24F 3/00 - Systèmes de conditionnement d'air dans lesquels l'air conditionné primaire est fourni par une ou plusieurs stations centrales aux blocs de distribution situés dans les pièces ou enceintes, blocs dans lesquels il peut subir un traitement secondaire; Appareillage spécialement conçu pour de tels systèmes
