An air conditioner includes an airflow path configured to direct an airflow 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 hybrid evaporative cooler system can include an evaporative cooler, a cooling coil, and a controller. The evaporative cooler can be located in an airstream and the cooling coil can be located in the airstream downstream of the evaporative cooler. The cooling coil can be configured to receive a process fluid from a source. The controller can be configured to operate the hybrid evaporative cooler system in a dry mode on condition that the leaving process fluid temperature set point is greater than the minimum supply fluid temperature.

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.

The invention relates to a heat exchanger device with at least one heat exchanger (1) which is flowed through by a fluid, at least one fan (11) and at least one adiabatic air cooler (2) for cooling air which is drawn in from the surroundings by the fan (11), wherein the air that has been drawn in is conducted firstly through the air cooler (2) and subsequently through the heat exchanger (1) and the adiabatic air cooler (2) has at least one humidification means (3), which is arranged in the air cooler (2) and which is composed of a moisture-absorbing material and a liquid feed (4), which feeds a liquid to the humidification means (3) in order to keep the humidification means (3) moist. In order that the most uniform possible wetting of the humidification means and higher heat exchange performance can be made possible without an impairment of the stability and the handleability of the humidification means and without oversaturation of the humidification means in the upper region with the liquid, provision is made whereby the humidification means (3) comprises at least two mats (3a, 3b) arranged one above the other and whereby the liquid feed (4) has a distributor device (4a, 4b) which is arranged above each mat (3a, 3b) and which serves for uniformly distributing the liquid onto the mats (3a, 3b), wherein each distributor device (4a, 4b) is connected to a feed line (5) via which the distributor devices (4a, 4b) can be charged with the liquid.

A cooling system transfers thermal energy from a temperature-critical reservoir to a heat sink. The system has an intermediate reservoir which is thermally interposed between the temperature-critical reservoir and the heat sink. The intermediate reservoir serves as an energy buffer between the two reservoirs by accepting thermal energy from the temperature-critical reservoir, storing that energy, and then transferring it to a heat sink by means of a temperature-driven process rather than by means of a heat pump. Transfer of thermal energy from the intermediate reservoir to the heat sink is temporally coordinated with naturally occurring temperature variations of the heat sink so that all thermal energy transfer processes conducted by the system are temperature-driven.
