Well, if the aerospace company you are working for is Honeywell, then you could transfer to HBS and apply for any of the PCE openings posted on Honeywell Jobs. PCE stands for Performance Contracting Engineer, which involves energy auditing, among other things.
I'd like to hear from anybody that has experience or technical data (other than from the manufacturers website) concerning the performance of the Abbotly ESM System 4000. The manufacturer claims installation of the module will reduce energy consumption of refrigeration and air conditioning...
I am interested in your opinions regarding polarized refrigerant oil additive which is claimed to provide life extension and energy savings when added to AC or refrigeration systems. Snake oil or credible solution?
I've got a Microsoft Power Point slide presentation that shows HVAC componets in 3-d drawing format. 22 slides. Send me an E-mail at otta4415@comcast.net and I'll send you the 870 KB file.

Here is a list of equipment we use for commercial facility energy audits. Quantity of loggers and sensors vary with application and facility size.
Fluke 39 Power Meter
Fluke 80i-500s AC Current Clamp
Fluke TL223 Electrical Test Lead Set
Fluke 77-3 Digital Multimeter
Fluke 80TK Thermocouple...
VFD efficiency (in percent) varies as a function of HP rating and percent full operating speed. A discussion and chart of VFD efficiency ratings can be found at the bottom of page 7 in the Energy Matters, Winter 2002 issue. Available at...
Since posting the question in July, I have found the following information:
The affinity laws are valid only under constant efficiency conditions. When an impeller diameter is cut it increases the radial clearance between the impeller and the volute. This results to increased losses due to...
I see some engineers use a 2.5 exponent for calculating horsepower using the affinity laws instead of 3.0 to account for inefficiencies not captured in the fan laws.
Is there a technical reference for taking this position?
