A mission critical facility is an enclosed space whose failure can bring a significant loss to a business. An example of a mission critical facility is a data center which usually comprises computers, servers, storage equipment, networking equipment, telecom equipment and associated electrical components working 24/7. The electrical components in the data center produce a lot of heat that requires removal from the enclosed space by using an air conditioning system. This invention includes a fluid cooling apparatus that cools the enclosed space using optimum power and water consumptions. The enclosed space can be a mission critical facility including but not limited to a data center. The disclosed fluid cooling apparatus offers low power and water consumption by combining a mechanical cooling system with an evaporative fluid cooling system in one single apparatus. Some embodiments locate the condenser coil for the mechanical cooling system in the evaporative fluid cooling's exhaust air to save on space and power consumption, which is novel in the industry. Also, this invention proposes using pre-cooling techniques for fluid-coolers which further improves the efficiency of the fluid cooling system which is also novel in the industry. The disclosed fluid cooling apparatus has three modes of operation to optimize power and water consumptions. Also, the disclosed fluid cooling apparatus can be used to deliver cold air to the enclosed space, cold fluid to the enclosed space or an end user or a combination of both which is called hybrid-cooling.

Examples herein describe systems and methods for dynamic building ventilation control. A control system can include a controller that receives information from the indoor and outdoor sensor packages. The control system can compare indoor and outdoor air quality using information from the indoor and outdoor sensor packages. The controller can also determine a current operational state of a heating, ventilation, and air conditioning (HVAC) system, such as heating, cooling, and fan status. Based on the air quality comparison and current operational state, the controller can open a first damper and closing a second damper to change ventilation of a building.

A dynamic misting control system can supply water to a condenser coil in varying degrees. The control system can include a controller, flow regulator (e.g., pump or separate), and mist generator (e.g., spray nozzles or otherwise). The controller can read outdoor humidity and temperature and vary power to the pump accordingly. The controller can also compare temperatures of the condenser coil to the outdoor humidity and temperature in adjusting the voltage. This can include calculating a voltage based on a first temperature of a coolant supply line and a second temperature in a return line and comparing those temperatures to the outside temperature and humidity.

The present invention relates to a portable water dispenser for dispensing cooling water to an overheated compressor of an ACU. The water dispenser includes a splash guard and a core that is installed inside the splash guard. The core includes a magnet that firmly but temporarily attaches the water dispenser to the outer surface with the compressor. Water flow is controlled to convert the flow exiting a water hose into a uniformly distributed curtain covering the entire outer surface of the compressor. The splash guard prevents water loss because it redirects any splashes towards the compressor.

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 heating, ventilation, and/or air conditioning (HVAC) system having a return air recycling system that includes a heat exchanger configured to be disposed along a refrigerant circuit of the HVAC system and flow a refrigerant therethrough, an exhaust fan configured to direct return air across the heat exchanger to place the refrigerant in thermal communication with the return air and to exhaust the return air from the HVAC system, and a controller configured to adjust a speed of the exhaust fan, a flow rate of refrigerant through the heat exchanger, or both, based on feedback indicative of a temperature of the return air.

A water-cooling system for an air conditioning unit is presented. The water-cooling system has a solar panel, a water storage unit and a mist distribution system. The solar panel converts solar energy to electrical energy. The water storage unit has a submersible pump that has at least one intake port and an output hose. The water storage unit has a liquid reservoir may be supplied by a condensation drain of the air conditioning unit. The water storage unit may also have an overflow switch such that the unit can be turned off to prevent overflow into a house for example, or the liquid reservoir from drying up and burning out the submersible pump. The liquid taken in by the submersible pump is delivered to the mist distribution system which supplies the liquid to a plurality of distribution points. When the liquid is received at the distribution points, the liquid is sprayed in a misting pattern onto the air conditioning unit thus improving the performance of the air conditioning unit.
