A liquid level control apparatus includes a reception unit that receives information relating to an incoming direction of radiation; and a liquid control unit that controls, based on the received information relating to the incoming direction, liquid levels in a plurality of tanks that are provided around a device and that store a liquid, so that the liquid level in a tank positioned in the incoming direction relative to the device rises.

Examples relate to a method includes monitoring a set of parameters. The set of parameters are associated with a first set of computing components and a second set of computing components. The first set of computing components is located in a first region and the second set of computing components is located in a second region. The first region is positioned proximate a generation station control system associated with a generation station and the second region is positioned remotely from the generation station control system. Each computing system of the second set of computing components is configured to adjust power consumption during operation. The method also include adjusting power consumption at one or more computing components of the second set of computing components based on the set of parameters.

An energy optimization system for a building includes a processing circuit configured to generate a user interface including an indication of one or more economic load demand response (ELDR) operation parameters, one or more first participation hours, and a first load reduction amount for each of the one or more first participation hours. The processing circuit is configured to receive one or more overrides of the one or more first participation hours from the user interface, generate one or more second participation hours, a second load reduction amount for each of the one or more second participation hours, and one or more second equipment loads for the one or more pieces of building equipment based on the received one or more overrides, and operate the one or more pieces of building equipment to affect an environmental condition of the building based on the one or more second equipment loads.

A cooling tower for evaporative cooling of water is contained within an ISO-compliant shipping container frame, permitting stacking of cooling towers for transport and for certain industrial applications. A volume of fill media is contained within the frame. Spaced apart troughs underlie the fill media, running substantially the length of the fill media and connecting to a basin. Baffles are connected to one upper edge of the troughs, while an air flow space is positioned over the other upper trough edge. A water distribution system, with variable flow nozzles positioned closely above the fill media, sprays water over the upper surface of the fill media, where it moves by gravity down into the troughs. Fans atop the fill media move air vertically upward through the fill media.

A washer fluid delivery system includes, among other things, a washer fluid reservoir having a first zone with a first low point and a second zone with a second low point. A first valve is disposed in the first zone. The first valve is moveable back and forth between a flow permitting position and a flow restricting position in response to an amount of washer fluid within the first zone. A second valve is disposed in the second zone. The second valve moveable back and forth between a flow permitting position and a flow restricting position in response to an amount of washer fluid within the second zone. A pump operates to draw a washer fluid from the first zone through the first valve when the first valve is in the flow permitting position, and to draw a washer fluid from the second zone through the second valve when the second valve is in the flow permitting position.

An energy cost optimization system for a building includes HVAC equipment configured to operate in the building and a controller. The controller is configure to generate a cost function defining a cost of operating the HVAC equipment over an optimization period as a function of one or more electric loads for the HVAC equipment. The controller is further configured to generate participation hours. The participation hours indicate one or more hours that the HVAC equipment will participate in an economic load demand response (ELDR) program. The controller is further configured to generate an ELDR term based on the participation hours, the ELDR term indicating revenue generated by participating in the ELDR program. The controller is further configured to modify the cost function to include the ELDR term and perform an optimization using the modified cost function to determine an optimal electric load for each hour of the participation hours.

A blow case with an inlet pipe positioned to gravity direct debris to an outlet pipe. The inlet pipe having a discharge end sealed by gravity open clapper style check valve that is closed by activation of pneumatic pressure through a float style pneumatic valve. The check valve has a top mounted access port and aperture allowing for direct above ground servicing access to both the clapper inside the valve and has a removable clapper and access port for servicing the outlet pipe. The float style pneumatic valve is also top mounted for ease of service and removal and is remotely positioned from the outlet pipe to allow for removal of the valve for flushing of the debris from the blow case.

Method and apparatus for autonomously fueling machinery operating at fracking sites. Apparatus includes a main tank with a plurality of fuel lines individually coupled to the fuel tank. Pumps are connected to some of the fuel lines. Pump outputs are coupled to hoses extending to the machinery tanks to be refueled. The apparatus further includes a cap detachably connected to the hoses and machinery tanks. The fuel tank includes an intake filter capable of blocking approximately 10 micron contaminants with about 250 gallon per minute flow. The methodology of the present invention includes measuring the duration of machinery tank fuelings and the interval between fuelings. A first alarm is generated if the duration of fuelings is longer than a first interval. A second alarm is generated if the interval between fuelings is longer than a second interval.
