HVAC Instrumentation and Control: Quick Book
ISBN: 9781505294156 / Angielski / Miękka / 2014 / 136 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) The HVAC systems are designed for peak conditions. Because these conditions prevail only for small period in a year, the HVAC equipment must operate most of the time at lean capacity. The function of the control system is to adjust the equipment capacity to match the load. Automatic controls are necessary not only to achieve the design conditions in the conditioned space but are also required for efficient operation of the HVAC system. The main parameters to be controlled in air conditioning system are temperature, pressure, humidity, air quality and thermal energy distribution. This 6 -hour...

Heat Rejection Options in HVAC Systems: Quick Book
ISBN: 9781505381672 / Angielski / Miękka / 2014 / 70 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) 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...

Principles and Methods of Temperature Measurement: Quick Book
ISBN: 9781502848635 / Angielski / Miękka / 2014 / 80 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) Temperature is a principle parameter that needs to be monitored and controlled in most engineering applications such as heating, cooling, drying and storage. Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic be it a thermal expansion, thermoelectricity, electrical resistance or thermal radiation. There are four basic types of temperature measuring devices, each working on a different principle: 1.Mechanical (liquid-in-glass thermometers, bimetallic strips, bulb & capillary, pressure type etc.)...

Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) The satisfactory performance and continuous reliability of electrical system greatly depends on the quality of wiring. Improperly or carelessly installed wiring can be a source of both immediate and potential danger, and many malfunctions and failures can be traced to this cause. This course describes many of the techniques used to prepare wire (cutting, stripping, crimping), install various types of connectors (soldered and solderless), and how to properly build and route harnesses and conduits. It will help the user understand wiring fundamentals, grasp the principles of circuit connections...

Punjabi: A Cognitive-Descriptive Grammar
ISBN: 9780415003209 / Angielski / Twarda / 1993 / 460 str. Termin realizacji zamówienia: ok. 22 dni roboczych (Bez gwarancji dostawy przed świętami) This is a complete grammatical description of Panjabi, an Indo-European language spoken in India and Pakistan, as well as in other countries outside Asia (particularly in the United Kingdom and Canada) by approximately 45 million people, either as a first or a second language. It is recognized as one of the 15 official languages of India. Primarily written in three distinct scripts (Gurumukhi, Perso-Arabic, and Devanagari), a unique feature of the language is that it is tonal in nature. Along with Lahanda and the Western Pahari (Himalayan) dialects, Panjabi is the only modern Indo-European...

Circuit Protection Devices: Quick Book
ISBN: 9781508517160 / Angielski / Miękka / 2015 / 44 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy 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...

Principles of Air Conditioning: Quick Book
ISBN: 9781503331426 / Angielski / Miękka / 2014 / 48 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) 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...

HVAC - Centralized vs. Decentralized Air Conditioning Systems: Quick Book
ISBN: 9781505284959 / Angielski / Miękka / 2014 / 64 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) Successful Heating, Ventilating, and Air Conditioning (HVAC) systems are the key to successful buildings. Because each building is different, it is very important to choose a system that is right for the facility. Proper selection of the HVAC system is a crucial decision for any new project and the decision depends upon a number of factors like how large area needs to be cooled, what is the application, what kind of total heat is generated inside the enclosed area, the developer's preference - initial installation cost, aesthetics, and long term maintenance and life cycle costs etc etc. The...

Control Valve Basics - Sizing & Selection: Quick Book

Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy przed świętami) 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...

Direct Current Generators: Quick Book
ISBN: 9781508497028 / Angielski / Miękka / 2015 / 52 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych (Bez gwarancji dostawy 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...
