摘要： The cooling systems and methods of the present disclosure involve modular fluid coolers and chillers configured for optimal power and water use based on environmental conditions and client requirements. The fluid coolers include wet media, a first fluid circuit for distributing fluid across wet media, an air to fluid heat exchanger, and an air to refrigerant heat exchanger. The chillers, which are fluidly coupled to the fluid coolers via pipe cages, include a second fluid circuit in fluid communication with the air to fluid heat exchanger and a refrigerant circuit in thermal communication with the second fluid circuit and in fluid communication with the air to refrigerant heat exchanger. Pipe cages are coupled together to allow for expansion of the cooling system when additional cooling capacity is needed. The fluid coolers and chillers are configured to selectively operate in wet or dry free cooling mode, partial free cooling mode, or mechanical cooling mode.

摘要： Systems and methods are provided and include a variable frequency drive configured to drive a fan motor of an HVAC system to ventilate an indoor space, the HVAC system having a cooling assembly that includes at least one of an economizer and a compressor. A controller is configured to communicate with the variable frequency drive, receive at least one signal from an occupancy sensing device, determine whether the indoor space is less than fully occupied based on the at least one signal, and control the variable frequency drive to reduce a speed of the fan motor in response to determining that the indoor space is less than fully occupied.

摘要： Chiller control systems and methods for chiller control use iterative modeling of cooling towers, heat exchangers, and pumps to determine the feasibility of integrated free cooling and the ability to take advantage of free cooling. The control systems and control methods can further include selecting the parameters for operating in the free cooling or integrated free cooling mode to improve efficiency and/or reduce energy consumption when operating in these modes. The models can have inputs and outputs that feed into one another, and converge at a solution over multiple iterations. The feasibility of integrated free cooling can be based on providing cooling to a cooling load process fluid at a heat exchanger. The availability of free cooling can be based on the cooling provided at the heat exchanger achieving a target temperature for the cooling load process fluid.

摘要： Conditioning systems and methods for providing cooling to a heat load can include an evaporative cooler arranged in a scavenger plenum with a pre-cooler upstream and a recovery coil downstream of the evaporative cooler. Outdoor or scavenger air can be conditioned in the evaporative cooler such that the conditioned scavenger air can provide cooling to a cooling fluid circulating through the recovery coil. The reduced-temperature cooling fluid can provide liquid cooling or air cooling for an enclosed space (for example, a data center) or for one or more devices that are enclosed or open to the atmosphere. Given the design and arrangement of the pre-cooler, evaporative cooler and recovery coil in the plenum, the system can operate in multiple modes. The pre-cooler can be configured to circulate a cooling fluid to condition the scavenger air. The pre-cooler fluid circuit can be coupled or decoupled from a process cooling fluid circuit.

摘要： An energy exchanger is provided. The exchanger includes a housing having a front and a back. A plurality of panels forming desiccant channels extend from the front to the back of the housing. Air channels are formed between adjacent panels. The air channels are configured to direct an air stream in a direction from the front of the housing to the back of the housing. A desiccant inlet is provided in flow communication with the desiccant channels. A desiccant outlet is provided in flow communication with the desiccant channels. The desiccant channels are configured to channel desiccant from the desiccant inlet to the desiccant outlet in at least one of a counter-flow or cross-flow direction with respect to the direction of the air stream.

摘要： Cooling units are provided. The cooling units include a base having a housing with control components and a cooling tower attached to the base and having an inner flow path and an exterior surface. An air distribution system is attached to the cooling tower and includes an air distribution chamber defined between first and second enclosures, air dispensers are configured in the first enclosure, and a cover is disposed on an exterior surface of the second enclosure. The control components are configured to convey air through the base, the cooling tower, and the air distribution system to dispense air through the cool air dispenser and the warm air dispenser. A cooling unit water supply is arranged to provide cooling water to the air distribution system through the cooling tower and a water treatment module connected to the cooling unit water supply to treat the cooling water.
