Direct Current Generators: Quick Book
ISBN: 9781508497028 / Angielski / Miękka / 2015 / 52 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) A direct current generator, or DC generator, produces a voltage of constant polarity, which means the voltage and current do not change over time. DC generators are basically AC generators whose output voltage is switched the other way round at the proper moment, so that the direction of the voltage is always in a single direction. The AC generator uses slip rings to transfer the current to the electrical circuit, while the DC generator uses a split-ring commutator. Generators can be very small or quite huge. Commercial DC generators are commonly found in traction applications like subways...

ISBN: 9781502824059 / Angielski / Miękka / 2014 / 182 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) The heating, ventilation and air conditioning (HVAC) systems can be the notorious contributors to nuisance noise in buildings. The HVAC systems and their components must be designed, installed and operated in such a way that any noise they may cause inside the building or neighboring buildings are at levels that do not cause any serious discomfort to the occupants. Noise control is not an exact science; however there are numerous ways the noise can be reduced from a particular source. The most desirable way to control excessive noise levels is by using engineering controls such as application...

HVAC Heating Load Calculations and Principles: Quick Book
ISBN: 9781503361829 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) The prime requirement in respect of the indoor climate in a building is that room temperature should be at a comfortable level, regardless of the weather conditions outside. As soon as the ambient temperature is lower than the indoor temperature, heat flows out from the building through its boundary surfaces (the building envelope). At the same time, the building also loses heat through air infiltration, i.e. the inward leakage of outdoor air into the building through gaps and cavities in walls, roofs, doors and windows. Bearing in mind the fact that the indoor temperature in most buildings...

Electrical Conductors: Quick Book
ISBN: 9781508498216 / Angielski / Miękka / 2015 / 30 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) A conductor is a piece of metal used to conduct electricity, known colloquially as an electrical wire. Wires are very good conductors, which mean that they have very little resistance. In fact, their resistance is so small that often we consider it to be zero. (In other words, we often treat wires as perfect conductors). In United States, conductors are measured by American wire gauge (abbreviated AWG) for smaller ones, and circular mils for larger ones. To give you some idea how thick these wires are; AWG 0000 wire is about 11.7 millimeters in diameter (a little less than one-half inch...

Compressors and Compressed Air Systems: Quick Book
ISBN: 9781505391787 / Angielski / Miękka / 2014 / 130 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych (Dostawa przed świętami) 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 (Dostawa przed świętami) 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 (Dostawa przed świętami) 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...
