A desuperheater of a heating, ventilation, and/or air conditioning (HVAC) system includes a first conduit defining a first fluid flow path configured to receive a refrigerant, and a second conduit defining a second fluid flow path and configured to facilitate heat transfer between the first fluid flow path and the second fluid flow path. The desuperheater also includes an inlet of the second conduit configured to receive collected water into the second fluid flow path. The desuperheater also includes a ventilation hole disposed in the second conduit and configured to vent water vapor from the second fluid flow path.

A once-through dry adiabatic cooler having an integrated factory installed air pre-cooler system that is mechanized to move from a shipping position to an operational position.

An air conditioner includes an air flow path configured to direct an air flow in a direction. The air conditioner also includes an evaporative cooling membrane panel disposed within the air flow path and including a face disposed at an oblique angle relative to the direction. The face is defined by microporous fibers of the evaporative cooling membrane panel. Each microporous fiber is configured to receive liquid in a fluid flow path of the microporous fiber such that the air flow over the microporous fiber generates a vapor. Each microporous fiber is also configured to release the vapor into the air flow via pores of the microporous fiber.

A cooling system using indirect evaporative cooling (IEC) is disclosed. The implementation discloses use of two stages of IEC with two separate IEC exchangers. The two-stages of IEC exchangers are arranged in a manner such that the prime air mover (primary blower) pulls (sucks) air through one exchanger (1st stage) and then pushes air through the other exchanger (2nd stage).

A plate for a heat exchanger including front and back external surfaces, a periphery, one or more dry internal passages through which a fluid flows parallel to the first and second stream-wise edges, and an internal frame. The frame is coincident with the periphery of the plate. The front edge section and the back edge section of the frame permit a fluid to flow into and out of the internal passages of the plate. The frame is bonded to the front and back external surfaces of the plate around the plate's periphery. The plate further includes fins or other protuberances that enhance heat transfer between a fluid flowing within the plate and the external surfaces of the plate, the fins or other protuberances being located within a volume defined by the frame and the plate's external surfaces.
