A direct evaporative cooler includes a liquid delivery system and an assembly of two or more plates. At least one plate of the assembly of two or more plates may include a top surface having a wicking material with an exposed surface for receiving a liquid thereon from the liquid delivery system, and one or more masks lining a portion of the exposed surface. The one or more masks may be impermeable to the liquid thereby preventing the liquid from evaporating through the one or more masks, and the one or more masks may be sized and shaped such that a wick rate of the liquid on the exposed surface exceeds an evaporation rate of the liquid.

A combined housing for temperature control of a space has a top face, a bottom face, a left side face, a right side face, a front face, and a rear face. A heating assembly formed in the housing has a recess centrally positioned in the front face and a radiant heating element extending laterally within the recess. A cooling assembly formed in the housing has an input aperture formed in the rear face equally spaced from the left and right side faces, a first output aperture formed in the front face between the recess and the left side face, and a right output aperture formed in the front face between the recess and the right side face.

A two stage evaporative cooling device has a central chamber, divided into an upper chamber and a lower chamber by a divider. one or more heat exchange units surrounding the central chamber; an upper fan arranged above the upper chamber and a lower fan arranged below the lower chamber; and a water circuit; wherein each heat exchange unit comprises an evaporative cooling element and an air to water pre-cooler, the pre-cooler being placed ahead of a lower portion of the cooling element and the water circuit is arranged to irrigate the cooling element and collect the irrigated water below the cooling element for delivery to the pre-cooler whereby pre-cooled air may be drawn inwardly through the pre-cooler and the lower part of the cooling element by the lower fan and ambient air may be drawn inwardly through the upper part of the cooling element by the upper fan.

An apparatus includes a mister having an on state and an off state. A thermostat is coupled to an air conditioner compressor and to the mister. The thermostat informs the mister when the air conditioner compressor is running and the mister uses that information to determine whether to transition between the on state and the off state.

An environmental control system according to an example of the present disclosure includes a heat exchanger, a ram air duct operable to provide cooling ram air to the heat exchanger, and a water extractor operable to extract water from the ram air. The heat exchanger includes at least one nozzle operable to spray water from the water extractor into the ram air duct. An example heat exchanger and a method of making a heat exchanger are also disclosed.

An indirect evaporative cooling air conditioner is provided, which includes a housing, multiple partition plates located in the housing and at least two heat exchangers arranged side by side. The multiple partition plates and the at least two heat exchangers separate the housing into multiple indoor air flow passages and multiple outdoor air flow passages, each heat exchange has a first heat exchange flow passage and a second heat exchange flow passage crosswise and independently arranged, the indoor air flow passages are in communication with the first heat exchange flow passages to form an indoor circulation passage, the outdoor air flow passages are in communication with the second heat exchange flow passages to form an outdoor circulation passage, and the fluid in the indoor circulation passages exchange heat with the fluid in the outdoor circulation passages through the at least two heat exchangers.
