20090293517 | REFRIGERATION SYSTEM WITH A CHARGING LOOP - A refrigeration system includes a primary loop that cools a secondary loop that circulates a coolant through a refrigeration load. The secondary loop includes a suction header to receive the coolant from the load, and a discharge header to direct the coolant to the heat exchanger, and a pump to pump the coolant from the suction to the discharge header. A charging loop maintains a pressure of the coolant in the supply header within a predetermined range, and includes an inlet from the discharge header and an outlet to the suction header. A flow nozzle and a valve are located between the inlet and the outlet, and a reservoir of make-up coolant communicates with the flow nozzle. Upon a low pressure condition in the suction header, the valve opens to permit flow of coolant through the flow nozzle to draw in make-up coolant from the reservoir. | 12-03-2009 |
20090308090 | COOLING METHOD AND APPARATUS - An apparatus and method to cool compressors, condensing coils, and similar devices. The compressor or condensing coil is cooled by the delivery of water, which may be ambient temperature or chilled. In one embodiment, the water is delivered to a mesh filter or screen via one or more mist spray nozzles. Water conduits may be integrated with the filter frame. The method to control the delivery of the water is designed to conserve water. The control circuit comprises a microcontroller device which contains programming that receives inputs, including but not limited to, outside ambient air temperature, condenser liquid line temperature, relative humidity and electric current, and uses said inputs to provide a stepwise level of control (“solenoid open time”) of water delivery commensurate with outside air temperature and relative humidity. | 12-17-2009 |
20100313584 | WATER CONSERVATION SYSTEM FOR EVAPORATIVE COOLER - A water conservation system for an evaporative cooler includes one or more probes located proximate to one or more evaporative cooler pads of an evaporative cooler. The probe(s) can detect a resistance level, a humidity level, and or a moisture level associated with the evaporative cooler pad. A controller communicates with the probe(s) and a valve for delivering water to the evaporative cooler pad, wherein the controller automatically turns the valve on or off, depending upon the moisture, resistance and/or humidity detected by the probe(s) in order to conserve water during operations of the evaporative cooler. Sensors can thus be utilized to detect the moisture level, humidity and/or resistance of the pad(s) to control the operation of a water pump for the delivery of water to the pads(s). | 12-16-2010 |

20110289951 | THERMOSYPHON COOLERS FOR COOLING SYSTEMS WITH COOLING TOWERS - In one embodiment, a cooling system may include a thermosyphon cooler that cools a cooling fluid through dry cooling and a cooling tower that cools a cooling fluid through evaporative cooling. The thermosyphon cooler may use natural convection to circulate a refrigerant between a shell and tube evaporator and an air cooled condenser. The thermosyphon cooler may be located in the cooling system upstream of, and in series with, the cooling tower, and may be operated when the thermosyphon cooler is more economically and/or resource efficient to operate than the cooling tower. According to certain embodiments, factors, such as the ambient temperature, the cost of electricity, and the cost of water, among others, may be used to determine whether to operate the thermosyphon cooler, the cooling tower, or both. | 12-01-2011 |

20160143449 | METHOD AND SYSTEM FOR CONTROLLING EVAPORATIVE AND HEAT WITHDRAWAL FROM A PATIENT SUPPORT SURFACE - 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 | 05-26-2016 |
