Many aspects of control are presented including air handling units, terminal units, chillers, boilers, building airflow, water and steam distribution systems, smoke management, and indoor air quality. Discussions of pneumatic, electric, electronic, and digital controls illustrate that applications may use one or more of several different control methods. Engineering data such as equipment sizing, use of psychrometric charts, and conversion formulas supplement and support the control information.

1995 white & green hardcover in very good+ condition; some wear to covers, good binding, no marks inside. US media mail only for shipping.While effective control of temperature loops is extremely important, achieving that control can be difficult because of thermal lags in both the process and measurement. In a properly tuned temperature loop, control errors can often be an order of magnitude less than those seen. This book provides a step-by-step approach for analysis of all the factors that affect the control of temperature loops, including major sources of measurement errors. Tuning guidelines are introduced that account for slow process, sensor, and poor valve response. The advantages and disadvantages of new methods for feedback control and autotuners are discussed. Suggestions for improving control of temperature loops are also provided. Contents: Measurement error controllers temperature loop analysis exchangers reactors columns vessels, desuperheaters, dryers, kilns, calciners, crystalizers,… Read More

The answers to these questions may be easier to answer than many modern physicists have made them. They could be based on obvious conclusions that come from observation of the wonderful cosmic images provided by our astronomers and their advanced telescopes. Our universe may be beautiful and exciting, but also easily understood.

2000 black board piral binding book in very good condition; some wear to covers, good binding, no marks inside. US media mail only for shipping. Learn the night skies of the Northern Hemisphere with Celestron Sky Maps! This classic collection of seasonal star charts, topped off by a glow-in-the-dark luminous star finder, or planisphere, has been around for years and years! It continues to be so popular because beginning stargazers as well as seasoned amateur astronomers find that this book provides most everything they need to find constellations quickly and delve into seasonal night sky treasures with ease. The front cover of this publication will be used well and often! It is a planisphere—a rotatable star wheel that can be aligned with any date and time (past, present & future), resulting in a display of the night sky for that period of time. When the star finder is pre-exposed to light, all of the major stars will glow in the dark, mimicking the way they actually look in the night sky. Inside… Read More

The technological and economical impact of a large central power station in Earth orbit on the performance and cost of future spacecraft and their orbital transfer systems are examined. It is shown that beaming power to remote users cannot be cost effective if the central power station uses the same power generation system that is readily available for provision of onboard power and microwave transmission and reception of power through space for use in space is not cost competitive with onboard power or propulsion systems. Laser and receivers are required to make central power stations feasible. Remote power transmission for propulsion of orbital transfer vehicles promises major cost benefits. Direct nuclear pumped or solar pumped laser power station concepts are attractive with laser thermal and laser electric propulsion systems.
