Definitions

  • the present disclosure relates to direct current (DC) air conditioning systems including an air mover cover for such systems.
  • DC direct current
  • Direct current (DC) environmental temperature control systems also referred to as air conditioning systems
  • DC air conditioning systems are often used to control the temperature within enclosed environments where alternating current (AC) ETCSs are not feasible, desirable or reliable.
  • AC alternating current
  • DC air conditioning systems have a capacity suitable for efficiently controlling the temperature of environments enclosed by smaller structures or buildings.
  • DC air conditioning systems are very suitable for controlling the temperature within utility sheds, portable or mobile structures, and electronics cabinets and utility or equipment structures such as cellular wireless communication electronic cabinets and battery backup closets.
  • Such smaller structures can be located in a wide variety of outdoor locations that present a myriad of rigorous exterior environmental conditions that affect the temperature within the structures. That is, the structures can be exposed to a wide range of external temperatures, e.g., - 30 0 C to 55°C, varying solar loads and various forms of precipitation that can all affect the internal environmental temperature. In the case of equipment cabinets, temperature control requirements can be stringent in order to prevent damage to the often expensive and not notably rugged equipment inside. Thus, employment of DC air conditioning systems is often desirable for actively controlling the temperature enclosed environment of such smaller structures. And in many cases, efficiency, consistency and reliability are critical necessities of the DC air conditioning system.
  • DC air conditioning systems include a condenser assembly and an evaporator assembly both of which are positioned within a housing.
  • the evaporator assembly receives air from an enclosed environment through a first opening in the housing, and an air mover pushes the air across a heater or an evaporator heat exchanger to condition the air (i.e., to heat or cool the air) before outputting the air through a second opening in the housing into the enclosed environment.
  • an air mover cover may be mounted over the first opening to allow air into the evaporator assembly.
  • these covers are made of sheet metal having edges which are sealed together by using a sealant, such as a room temperature vulcanizing sealant, or by welding the edges together.
  • a sealant such as a room temperature vulcanizing sealant
  • These seals or welds are time consuming to apply, costly and prone to failure. Over time these seals and/or welds may deteriorate, which may compromise the effectiveness of the evaporator assembly.
  • an evaporator air mover cover for a direct current (DC) powered variable capacity air conditioning system having a housing enclosing an evaporator assembly.
  • the housing defines an air intake opening for intaking air from an enclosed environment into the evaporator assembly.
  • the evaporator air mover cover includes a single piece seamless structure positioned over the air intake opening for covering at least a portion of the air intake opening. Further, the evaporator air mover cover allows air from the enclosed! environment to flow through the air intake opening and into the evaporator assembly.

  • the system further includes an air mover cover comprising a single piece seamless structure and positioned over the air intake opening for covering at least a portion of the evaporator air mover. The air mover cover allows air from the enclosed environment to flow through the air intake opening and into the evaporator assembly.
  • a direct current (DC) powered variable capacity air conditioning system having a housing defining an air intake opening, and an evaporator assembly including a plurality of components enclosed in the housing and positioned adjacent the air intake opening.
  • the system further includes an evaporator air mover cover having a transparent panel positioned over the air intake opening for covering at least a portion of the evaporator assembly including at least a portion of the components. The portion of the components is visible through the transparent panel.
  • a direct current (DC) powered variable capacity air conditioning system having a housing defining an air intake opening, and an evaporator assembly enclosed in the housing and positioned adjacent the air intake opening.
  • the system further includes an evaporator air mover cover including a guard and a screen having at least one edge, the evaporator air mover cover defines a second opening.
  • the evaporator air mover cover is positioned over the air intake opening for covering at least a portion of the evaporator air mover.
  • the guard is positioned at least partially around the second opening, the screen is positioned over the second opening, and the at least one edge of the screen is positioned on the guard for preventing the at least one edge from being exposed.
