A cooling assembly includes a plurality of dry coolers. Each dry cooler has an air intake, an air outtake, a heat exchanger panel for exchanging heat with air pulled into the dry cooler, and a fan rotating about a fan rotation axis for pulling air into the dry cooler and rejecting heated air out of the dry cooler. The heat exchanger panel includes a tubing arrangement for circulating fluid therein. The dry coolers are arranged in a plurality of dry cooler stacks. Each dry cooler stack includes a first dry cooler and a second dry cooler disposed above the first dry cooler. The dry cooler stacks are positioned such that the dry coolers of each dry cooler stack reject heated air into a common heat rejection zone. Each dry cooler is oriented such that the fan rotation axis of the dry cooler is substantially transversal to a vertical axis.

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.

An air conditioning apparatus includes an outdoor device that is configured to circulate refrigerant and that includes a compressor and an outdoor heat exchanger, a plurality of indoor devices configured to circulate water, and a heat exchange device that connects the outdoor device with the indoor device. The heat exchange device includes a heat exchanger configured to exchange heat between the refrigerant and the water, and a switch device configured to control flow of refrigerant between the indoor device and the heat exchanger.

Embodiments of the current disclosure include air pretreatment devices suitable for pretreatment of air received by air handler units. The air pretreatment devices can include an air intake configured to capture the outside air. A cooling coil system can process changes in the dry bulb and dew point temperatures of the captured outside air. The pretreated air can then be passed via an air outtake to the air handler. The cooling coil system can be coupled to at least a chilled water intake and a chilled water return line. Finally, a single water valve control unit located on either the chilled water intake or chilled water return line can be adjusted to direct a change in the dry bulb temperature and dew point temperature within the cooling coil system.

An air handling unit (AHU) comprises a shell defining a cavity and comprising at least an air ingress on a shell surface and an air egress on another shell surface, a condensing coil disposed with the cavity, a cooling coil disposed between the air ingress and the condensing coil, and an energy recovery coil disposed between the condensing coil and the air egress.

A water extractor includes a plurality of layers of low pressure zones and a plurality of channels of high pressure zones. The low pressure zone layers alternate, in a radial direction, with the high pressure zone channels. At least one of the low pressure zones is configured to enable a flow to enter, from at least one high pressure zone, to at least one low pressure zone.

A magnetic refrigeration module includes a housing, low and high temperature inflow paths, low and high temperature outflow paths, and first and second intermediate flow paths. The housing houses a magnetic working substance, and forms a flow path. The low and high temperature inflow paths carry heating medium into first and second ends of the flow path. First and second spaces are formed between the first and second ends and the low and high temperature inflow paths. The low and high temperature outflow paths receive the heating medium from the first and second ends of the flow path. The first and second intermediate flow paths communicate with the low and high temperature inflow paths and the first and second spaces. The first and second intermediate flow paths expand heating medium flow from the low and high temperature inflow paths to the first and second spaces.

A blower device includes a Coanda effect fluid flow amplifier having a suction opening, an outlet opening to provide an amplified fluid flow, an inner passage along an amplifier central axis passing through the suction opening and the outlet opening. An inlet conduit inputs pressurized fluid into the inner passage for drawing the ambient fluid from the suction opening to the outlet opening by Coanda effect, achieving amplified flow. A diffuser downstream of the amplifier includes diffuser side walls that delimit a diffuser inner side surface extending about a diffuser central axis arranged along the amplifier central axis and terminates with a first flow inlet open end facing the outlet opening, and an opposite second flow outlet open end delivers further amplified fluid flow. At least one side opening is upstream of the second flow outlet open end to allow additional ambient fluid to be sucked into the diffuser.
