Method and System for Controlling Evaporative and Heat Withdrawal Performance of an Occupant Support Surface

Номер: US20120012277A1
Автор: Charles A. Lachenbruch
Принадлежит: Individual

A method for controlling performance of an MCM capable support surface having a flowpath for guiding a stream of air along at least a portion of the surface, comprises specifying a desired evaporative rate greater than an evaporative rate achievable with unconditioned ambient air, chilling the unconditioned ambient air to a temperature at least as low as that required to achieve 100% relative humidity, thereby demoisturizing the air, and supplying the chilled, demoisturized air to the flowpath. The method may also include the step of heating the chilled, demoisturized air prior to step of supplying it to the flowpath. A system for carrying out the method includes a microclimate management (MCM) capable support surface 22 , a chiller 60 for cooling air to be delivered to the MCM capable surface, a user interface 42 for receiving instructions concerning desired microclimate management performance, and a controller 50 , responsive to the instructions, for operating the chiller.

Sub-wet bulb evaporative water chiller with gradient chilling and air-to-air heat exchange

Номер: US20120204591A1
Автор: Eric Edward Jarvis
Принадлежит: Individual

An evaporative chiller cooling water to below ambient wet bulb temperature. Sub-wet bulb chilling is achieved by pre-cooling incoming air upstream of the saturator. The incoming air is ambient air at ambient air temperature that is cooled using the coolness of the lower temperature outgoing air exiting the saturator. The pre-cooling lowers the temperature of the incoming air and lowers its wet bulb temperature below that of ambient air. The saturator water is chilled to below the ambient wet bulb temperature. The air in the saturator flows across the water as it gravity drips or flows from the top to the bottom of the saturator. The pre-cooled air flows across the saturator with the coolest air directed across the bottom of the saturator where the coldest water is flowing and with the hottest air directed across the top where the hottest water is flowing to provide gradient chilling.

A cooling system ( 20 ) includes a media exchanger ( 50 ), a cooling section ( 22 ), and a cooling circuit ( 120 ) for circulating a cooling fluid ( 130 ) between the media exchanger ( 50 ) and the cooling section ( 22 ). The media exchanger ( 50 ) receives outside air ( 38 ) and the cooling section ( 22 ) receives return air ( 32 ) from and interior space ( 34 ). When the cooling fluid ( 130 ) circulates into the cooling section ( 22 ) via the cooling circuit ( 120 ), the temperature of the return air ( 32 ) is reduced through indirect heat transfer between the cooling fluid ( 130 ) and the return air ( 32 ) to produce conditioned air ( 84 ). The conditioned air ( 84 ) is provided as supply air ( 46 ) into the interior space ( 34 ). When the cooling fluid circulates into the media exchanger via the cooling circuit, the temperature of the cooling fluid is reduced through direct heat transfer between the cooling fluid and the outside air.

An evaporative cooling apparatus includes a liquid reservoir and a pump coupled to the liquid reservoir. The pump includes a pressure output that applies a static pressure against the liquid stored in the liquid reservoir. The applied pressure forces liquid through a liquid supply line to a nozzle unit, and the liquid is ejected into a stream of forced air from a fan for evaporative cooling applications. The pressure output is also in fluid communication with the nozzle unit via a gas supply line extending between the pressure output and the nozzle unit for delivering gas into the nozzle unit. The gas delivered to the nozzle unit interacts with the liquid inside the nozzle unit to generate the atomized spray of liquid droplets.

A cooling system including a ventilator that exchanges atmosphere between parts of a building that are at differing heights. The ventilator includes an outer conduit that extends from an upper end thereof downward to a lower end thereof. An inner conduit extends substantially the entire length of the outer conduit. Both the outer and inner conduits are open at their respective upper ends and lower ends. Temperatures of atmosphere both surrounding and within the outer conduit and the inner conduit induce an exchange of atmosphere between the ventilator and surrounding atmosphere.

VARIABLE CAPACITY EVAPORATIVE COOLING SYSTEM FOR AIR AND WATER CONDITIONING

The invention relates to a multi-component air conditioning system that cools air below the pre-treatment wet bulb temperature without the use of a mechanical vapor compression system. A heat exchanger cools air followed by an evaporative cooling process that further cools the air through the vaporization of water. A heat rejection unit removes warm air from the system and cools water that can be recycled into a reservoir. A chamber separation plate can be moved to adjust the capacities of the cooling unit and the heat rejection unit. The flow of water through the system can also be controlled. This allows greater variability of capacity and temperature control. 1. A system for cooling air or water , said system comprising:a. a cooling unit;b. a heat rejection unit;c. a water management system; andd. a chamber separation plate;wherein the cooling unit is comprised of a sensible heat exchanger and an evaporative porous media unit;wherein the chamber separation plate separates the cooling unit and the heat rejection unit and is movable along a shaft such that its position determines the capacities of the cooling unit and the heat rejection unit.2. The system of claim 1 , wherein a control system maintains a target air and/or water temperature by controlling at least one of fan speed claim 1 , water circulation and the position of the chamber separation plate.3.
