A Space Age Test Center
The Air Force's Aeropropulsion System Test Facility (ASTF) is the most expensive project the Air Force has ever built. Its massive heaters, coolers and compressors will treat...

Lessons Learned from First Impulse Turbine Installation in the U.S. Mining Industry
The paper discusses a research study to recover energy from service or cooling water brought into deep mines. The test site was the Luck Friday Mine, owned and operated by the Hecla Mining...

Guideway and Conductor Rail Heating for a Winter Environment
The power and signal conducting rails are maintained using self-limiting heat trace cable in combination with an inherently protected rail. The cable's high inrush power along...

Portable Kerosene Heaters and Indoor Air Quality

Design Verification of HVAC Duct Turning Vanes in Nuclear Power Plants
HVAC ducts in nuclear power plants utilize short radius elbow construction with turning vanes to minimize the space requirement for duct work and to reduce flow losses in the elbows. Turning...

Evaluation of the Ultimate Pressure Capacity of Rectangular HVAC Ducts for Nuclear Power Plants
Structural design criteria are presently based on the AISI Code which limits the duct panel width-to-thickness ratio to a maximum of 500 and the maximum height-to-thickness ratio to 200,...

Experiments on Coaxial Heater Water Discharges
The paper describes an experimental investigation in which heated water was discharged coaxially into rectangular open channel flow from a slot placed at the channel center. Discharge...

Health Implications from Kerosene Heaters

Advanced Gas and Electric Residential Heating Technologies

District Heating and More Efficient Buildings

Tall Building Systems and Concepts
The structural, mechanical and electrical systems of tall buildings are explored. The eight areas of focus are, structural systems, mechanical and service systems, electrical systems,...

Solar Energy for Heating Homes: How Practical—
There is a widespread belief that on-site solar energy for heating homes is still not a proven technology and that, in any event, it's much too expensive. The fact is that...

A Structural Design Code for HVAC Equipment

A Procedure for Seismically Qualifying HVAC Ducts used in Nuclear Power Plants

Structural Testing of Seismic Category I HVAC Duct Specimens

Slow Trend for Asphalt with H2O
Cutback asphalt, made fluid by heating and by adding petroleum solvents, is becoming less popular because of the energy crisis and air pollution control standards. Replacing cutbacks are...

Seismic Support: Speedy Determination of Frequency
Seismic restraints are provided to support safety-related electrical cable trays or conduits and HVAC ductwork in nuclear power plant structures. It is shown that most of these restraints,...

What's New in Roofing—
For 75 years the waterproof membranes in roofs were made the same way—layers of bitumen alternating with layers of felt. Now for the first time prefabricated membranes of synthetics are...

Gophers Go Underground
A major facility, Williamson Hall, was constructed to be almost entirely below grade on the East Bank Campus of the University of Minnesota. Heating and cooling energy requirements will...

Old Roads Never Die, They are Just Recycled
The cost of repairing roads has increased as asphalt is dependent on the constantly growing price of petroleum. One answer to keeping down costs is asphalt recycling. This article takes...
