Compressors and Compressed Air Systems: Quick Book
ISBN: 9781505391787 / Angielski / Miękka / 2014 / 130 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Compressed air has many applications in industry. Delivering compressed air to a manufacturing facility is an expensive operation and it requires costly equipment that consumes significant amounts of electricity and needs frequent maintenance. Roughly 80 to 90 percent of the electricity used to operate compressed air systems is converted to low-temperature waste heat. This lost energy can quickly add up, each year costing individual facilities as much as double the purchase and installation cost (first-cost) of the entire system. The ideal time to think about your compressed air system is...

Circuit Protection Devices: Quick Book
ISBN: 9781508517160 / Angielski / Miękka / 2015 / 44 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Too much current flowing through an electric circuit can damage the circuit and can create a safety hazard. How much current is "too much current"? That depends on the circuit and its components. For some circuits, 1 ampere would be too much current, while for other circuits 1 ampere would be perfectly acceptable. Circuit protection devices protect electrical equipment by rapidly disconnecting power to components in the event of an abnormal overload conditions resulting from excessive voltages, ground faults, and accidental shorting of a circuit. Two types of circuit protection devices are...

Alternating Current Generators: Quick Book
ISBN: 9781508496786 / Angielski / Miękka / 2015 / 42 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. An alternating current generator, or AC generator, produces an alternating current, which means the voltage produced alternately reverses from positive to negative polarity, producing a corresponding change in the direction of current flow. Much like a DC generator, an AC generator requires a coil to cut across the force lines of a magnetic field. This coil is attached to two slip rings, which deliver the current to and from the load destination, thus completing the circuit. Alternating current generators are often called "Alternators." The magnitude of AC voltage generated by an AC generator...

Alternatives to Active HVAC Systems: Quick Book
ISBN: 9781508586609 / Angielski / Miękka / 2015 / 84 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The global energy scenario has undergone a drastic change in the last two decades. Due to ever growing demand and shortage of supply, the cost of fossil fuel (coal, oil and natural gas) is increasing day by day. Increasing consumption has led to environmental pollution resulting in global warming and ozone layer depletion. Consequently, the era of fossil fuel is gradually coming to an end and the attention is focused on the conservation of energy and search for renewable sources of energy, which are environmentally benign. Buildings are major consumers of energy insofar as their construction,...

Principles of Air Conditioning: Quick Book
ISBN: 9781503331426 / Angielski / Miękka / 2014 / 48 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Most people think the air conditioning system's job is just to add "cold" air to the space. Actually air-conditioning is a process to control temperature, humidity and air quality. Engineers define the process as one in which a system of mechanical components - usually a compressor, a fan, condenser coil, evaporator coil and a chemical refrigerant - extracts heat from indoor air and transfers it outside, leaving the cooled indoor air to be re-circulated. The cleaning function of air conditioners is performed by filters. Diverse geographical and operating conditions require considerably...

Control Valve Basics - Sizing & Selection: Quick Book
ISBN: 9781502841070 / Angielski / Miękka / 2014 / 142 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Control valves are imperative elements in any system where fluid flow must be monitored and manipulated. A complete control valve is made of the valve itself, an actuator, and, if necessary, a valve control device. The actuator is what provides the required force to cause the closing part of the valve to move and the valve control devices keep the valves in the proper operating conditions; they can ensure appropriate position, interpret signals, and manipulate responses. Selection of the proper valve involves a thorough knowledge of the process for which it will be used. When implementing a...

Overview of Electric Overhead Traveling (EOT) Cranes: e-Book
ISBN: 9781502515933 / Angielski / Miękka / 2014 / 202 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. An overhead crane, also known as a bridge crane, is a type of crane where the hook and line mechanism runs along a horizontal beam that itself travels on the two widely separated rails. Often it is in a factory building and runs along rails mounted on the two long walls. A gantry crane is similar to an overhead crane, but here the bridge carrying the trolley is rigidly supported on two or more legs moving on fixed rails embedded in the floor. Overhead traveling cranes are also available in various configurations. The two main categorizations are top-running versus under-running bridge cranes...

Heat Rejection Options in HVAC Systems: Quick Book
ISBN: 9781505381672 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. One of the basic requirements of the air conditioning and refrigeration system is to reject heat to the outdoors. The refrigerant chillers come in two different forms: An air-cooled chiller uses the flow of outside air across the condenser to remove or reject heat from the chiller. Air-cooled chillers typically have the condenser mounted on the roof or somewhere outside the facility while the evaporator can either be inside or outside the facility. Water-cooled chillers are typically 100 tons or greater and use water to remove the heat from the condenser. Water-cooled chillers are typically...

20 Ways to Optimize Efficiency in the Use of Induction Motors: Quick Book
ISBN: 9781508586296 / Angielski / Miękka / 2015 / 86 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The majority of electrical energy consumed in most industrial facilities is used to run electric motors. Annual energy operating costs of electric motors usually far exceed purchase prices. For example, a typical 25 horsepower (hp) motor running at full load for 6,000 hours per year would consume nearly $10,000 of electricity annually. An average purchase price for a motor of this size would be only $500 to $600. Energy efficiency decisions are important decisions that affect operating cost for the life of the equipment. By optimizing the efficiency of your motor-driven systems, you can...
