Question of the week 6-21-2015

Here’s how it works:
Must be an interNACHI member to win.

The Awards Committee panel member posts a question in the Education and Training section, once per week at a random time on a random day.

**All parts of the question must be answered in one post. You may not post more than once. The first(and only) post counts, get it right the first time.

Do not edit your posts as the Awards Committee can see that time stamp in the edited post…it just makes our sorting it out more cumbersome.**

First correct answer (as judged by the question poster, and the award committee) wins. The lucky winner gets one case of “Now that you’ve had a Home Inspection Books” shipped to you. Courtesy of Nick G. Your prize will be shipped to the address on file.

Good luck

A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. It is used in air conditioning equipment, as an automobile supercharger (where it is known as a scroll-type supercharger) and as a vacuum pump.
A scroll compressor operating in reverse is known as a scroll expander, and can be used to generate mechanical work from the expansion of a fluid, compressed air or gas. Many residential central heat pump and air conditioning systems and a few automotive air conditioning systems employ a scroll compressor instead of the more traditional rotary, reciprocating, and wobble-plate compressors.

A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.[1]]( [2]](
The intake gas enters the suction manifold, then flows into the compression cylinder where it gets compressed by a piston driven in a reciprocating motion via a crankshaft, and is then discharged. Applications include oil refineries, gas pipelines, chemical plants, natural gas processing plants and refrigeration plants. One specialty application is the blowing of plastic bottles made of polyethylene terephthalate (PET).
In the ionic liquid piston compressor many seals and bearings were removed in the design as the ionic liquid does not mix with the gas. Service life is about 10 times longer than a regular diaphragm compressor with reduced maintenance during use, energy costs are reduced by as much as 20%. The heat exchangers that are used in a normal piston compressor are removed as the heat is removed in the cylinder itself where it is generated. Almost 100% of the energy going into the process is being used with little energy wasted as reject heat.[3]](

A scroll compressor is inherently a supercharger when compared to a piston compressor


More efficient


Scroll compressors have a better energy efficiency ratios than piston compressor. Scroll compressors produce less noise and less vibration.

Jeff is the winner this week!!!

Scroll compressors are inherently 10-15 percent more efficient and require less equipment, starters, accumulators heaters.

Congrats Jeff

Congratulations, Jeff!

awesome! Thanks John and the others!
