HVAC Heating Load Calculations and Principles: Quick Book
ISBN: 9781503361829 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. 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. 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. 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...

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...

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,...

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...
