After the excellent May meeting with Mr. Harold Myers from H.E.Myers and assoc. I thought it would be appropriate to post about these new requirements for walk ins. These changes are significant and are probably only the wind before the storm ( so to speak).
Also, our chapter will end its schedule for the educational year with a chapter picnic at the Iron Pigs stadium. We will have a chapter raffle with the drawing at the picnic. There are a lot of nice prizes that were donated. Thank you to Meier supply http://www.meiersupply.com/ for the generous donation of the digital manifold gauge. Also, thanks to Kelly's Ice Creamery for the generous gift certificate for "got to be delicious treats". Some of your chapter members have selflessly donated the other gifts. Be sure to purchase a ticket as all proceed benefit the programs of the local chapter.
There may not be many posts during the busy summer months, but plan to be part of the training schedule for the 2009-2010 educational year. Devote yourself to improving your knowledge and skills. Make it a priority and commitment to yourself to get out of the rut you're in and learn or relearn what will make you a better technician. Don't settle for mediocre.
Under Federal Law,
New Construction and Design Requirements
for walk-in coolers and freezers …
…
ENERGY INDEPENDENCE AND SECURITY ACT OF 2007 (EISA)
Signed into law December 19, 2007 includes requirements in SEC. 312. relating to walk-in coolers and walk-in freezers manufactured on or after January 1, 2009.
Walk-in coolers and freezers are defined as an enclosed storage space refrigerated to temperatures, respectively, above, and at or below 32 degrees Fahrenheit that can be walked into, and has a total chilled storage area of less than 3,000 square feet. These requirements do not include products designed and marketed exclusively for medical, scientific,or research purposes.
In Summary, the requirements are:
Have automatic door closers that firmly close all walk-in doors that have been closed
to within 1 inch of full closure, except for doors wider than 3 feet 9 inches or taller
than 7 feet. Have strip doors; spring hinged doors, or other method of minimizing infiltration when doors are open.
Contain wall, ceiling, and door insulation of at least R-25 for coolers and R-32 for
freezers, except that this subparagraph shall not apply to glazed portions of doors nor
to structural members.
Contain floor insulation of at least R-28 for freezers.
Evaporator fan motors of under 1 horsepower and less than 460 volts, use
electronically commutated motors or 3-phase motors.
Condenser fan motors of under 1 horsepower, use electronically commutated motors,
permanent split capacitor-type motors or 3-phase motors;
Interior lights, use light sources with an efficacy of 40 lumens per watt or more
Transparent reach-in doors for walk-in freezers and windows in walk-in freezer doors
shall be of triple-pane glass with either heat-reflective treated glass or gas fill.

Transparent reach-in doors for walk-in coolers and windows in walk-in cooler doors
shall be of double-pane glass with heat-reflective treated glass and gas fill; or triplepane
glass with either heat reflective treated glass or gas fill.
If the appliance has an antisweat heater without antisweat heat controls, the appliance
shall have a total door rail, glass, and frame heater power draw of not more than 7.1
watts per square foot of door opening (for freezers) and 3.0 watts per square foot of
door opening (for coolers).
If the appliance has an antisweat heater with antisweat heat controls, and the total door
rail, glass, and frame heater power draw is more than 7.1 watts per square foot of door opening (for freezers) and 3.0 watts per square foot of door opening (for coolers), the antisweat heat controls shall reduce the energy use of the antisweat heater in a quantity corresponding to the relative humidity in the air outside the door or to the condensation on the inner glass pane.
