Abstract: According to an embodiment, a dynamic system and method for managing facility services that utilize scheduled predefined events and/or unscheduled variable events, are discussed. The dynamic system can include one or more servers, mobile devices, imaging devices, etc. designed and programmed to receive, manage, control, and/or report events from designated users. The dynamic system effectively manages the flow of work, efficiency of work and quality of work, and provides a common platform for communications within organizations, with their customers, and suppliers. The system can be effectively utilized by all service businesses and production operations to manage work flow, improve quality, minimize costs, and maximize labor utilization.

Abstract: A primary pan assembly for use in conjunction with an air conditioning system, which includes two primary plates and a silicon rubber cover which are assembled together to form the primary pan which includes a lower cylinder to be disposed at the assembled pan during installation thereof so as to pass a pair of built drain pipes through the lower cylinder, whereby the plastic primary pan can easily be assembled with the silicone rubber plate and tightly attached to the pair of built drain pipes.

Abstract: A plastic coupling device for connecting two building elements includes a T-shaped coupling member having two inwardly bent ends and an adjacent pair of W-shaped plates each having inwardly bent ends, respectively, for slidably, tightly receiving the T-shaped coupling member along adjacent side portions of the W-shaped plates so as to form a composite ceiling plate used in building ceilings.

Abstract: A plastic air filter housing assembly for use in air conditioning and heating systems which includes a base member having a pair of round shape longitudinal upper and lower edges and a plurality of transverse frames having a plurality of longitudinally frames to be cross located therewith connecting member and a locking member respectively for pivotally connecting to and slidably locking with the edges respectively, whereby the air filter housing assembly is easily assembled its components and easily replacing the air filter in the air filter housing assembly.

Abstract: A plastic primary pan assembly for use in conjunction with an air conditioning system which includes a C-shaped drain plastic pan, a pan cover having a raised portion disposed around a blow outlet thereof, and an U-shaped supporting bracket having a pair of locking end members and a pair of elongated channels and an elongated aperture being mounted on the fan cover and a motor through a motor plate, whereby the plastic primary pan assembly can be easily associated with and separate from the air conditioning system and easily adjusted to incline the plastic primary pan for draining condensate water through an outlet disposed in the plastic primary pan.

Abstract: Plastic primary pan assembly for use in air conditioning systems which includes a base primary pan containing a pair of blind plates having a pair of semi-cylinders, respectively, to be removed one of them from the base primary pan, a pair of rubber packings, and an assembly plate having a pair of semi-cylinders to be inserted into the base primary pan, after taking out one of the pair of blind plates from the base primary pan, assembling with a base primary pan instead of the blind plate so as to pass a pair of built drain pipe therethrough, whereby the plastic primary pan can easily assemble the base primary pan with the assembly plate, the pair of rubber packings, and the pair of drain pipes.
