Embodiments relate generally to a cooling system. One embodiment relates to a cooling system that rejects heat to a fluid loop or water coil that is upstream of an evaporator. Embodiments find particular use in connection with humidity and temperature ontrol systems for indoor uses, non-limiting examples of which include indoor pool environments, indoor agriculture growing facilities, or other indoor facilities that require humidity and temperature control.

There is presented a heating, ventilation and air conditioning (HVAC) system for conditioning air within a chamber, the system comprising: an inlet, an outlet, and a conditioning unit, the conditioning unit comprising a fan, and a heat exchanger configured to exchange heat with the air within the conditioning unit, wherein during operation, air is urged through conditioning unit by the fan such that heat is exchanged between the air and the heat exchanger, wherein the fan is configured to vary the flow rate of air urged through the conditioning unit to thereby control the amount of heat transferred between the air and the heat exchanger.

Atmospheric water generators, systems and methods are presented involve user authentication, recording and tracking of water volumes dispensed by respective users over periods of various lengths, controlling component noise level and timing, and cleaning, heating and cooling the collected water more efficiently. The generators may be placed in network communication with other such generators to exchange water availability information therewith, or may communicate with a central server element by way of LAN, Internet, cell tower, peer-to-peer mesh or satellite. Information is conveyed to the user regarding the amount of water they consume from the water generators, and their resulting positive impact on the environment. Water dispensing data may be shared on the users' social media accounts, or used as inputs for competitions or games in order to further engage the user. User authentication may be accomplished by way of biometrics or an RFID/NFC tag embedded in the user's water vessel.

An HVAC system with a reheat coil is described, the system includes a compressor, a micro-channel condenser and an evaporator. A reversing valve is connected to the compressor, the micro-channel condenser and the reheat coil. The reversing valve is used to direct the refrigerant from the compressor to the micro-channel condenser in a normal mode, and to direct the refrigerant from the compressor to the reheat coil in a reheat mode. The reversing valve can be switched from normal mode to reheat mode when a high pressure condition is detected at an input to the micro-channel condenser, and switched back from reheat mode to normal mode when the high pressure condition has resolved or an amount of time has passed. In the normal mode the refrigerant is returned from the reheat coil into a refrigerant line between the evaporator and the compressor through a restrictor.
