@ March 7, 2014 6:20 PM in New Seminar on AIR!I like gurantees and I like a good time. I have also been collecting air samples so I can find out what I have! Jack, I like! I'm going to the very 1st class, KindaSorta like opening day of baseball.
@ March 6, 2014 6:16 AM in Condensate drain trap question:I agree unclejohn, that has to be some nasty water!
@ March 6, 2014 6:05 AM in Completed boiler & chiller instalWOW ! Very very nice! I'm drooling here.lol. How about a breakdown of all of those colored pipes!! Whats inside of them? What type of facility?
@ March 6, 2014 5:59 AM in Burnham recall?Thanks Gents! I have a contractor that has several of these boilers, and I'll be making the changes .
@ March 5, 2014 7:28 PM in geothermal vs. airsourceThat was at a "Freon" class at Johnstone Supply ,providing memory is intact! Nor have I seen any 410a P/T problems.
@ March 5, 2014 7:15 PM in Burnham recall?Anyone hear about a problem with CO in the flue area on the some boilers and there is a correction kit?
@ March 5, 2014 6:17 PM in geothermal vs. airsourceI thought that 410a runs closer to that Critical Point than is desired at higher ambients and that is why 410a is on its way out.!?!?
@ March 4, 2014 2:51 PM in Spring is in the air!And so is the subject of properly charging AC units! In this months magazine by RSES, in the RSES Journal, an article by Adolfo Wurts of Fieldpiece Instruments talks about properly charging/testing/adjusting AC units by KNOWING and UNDERSTANDING and APPLYING SuperHeat and SubCooling. WITHOUT WEIGHING IN THE FREON!
@ March 4, 2014 2:23 PM in BTU Radiator Output? (see attached photo)What type of enclosure? Is there some kind of duct/air in/ air out/ fan? The heat doesn't get trapped?
@ March 4, 2014 7:06 AM in Leaking curved steam radiatorsOK Steamhead, what was the giveaway that the system looks like a Webster Vapor type? Very curious!
@ March 2, 2014 12:13 PM in geothermal vs. airsourceJust a thought.This is on the Freon temps/press for different freons. On a 95* ambient the head press/temp is no higher than 120-125*f condensing for each of those freons you mentioned . That 135*f for r-134 is a little high.
@ February 26, 2014 8:25 PM in Condensate drain trap question:The drain line exits the AirHandler horizontally then ,1- an ell goes down (6") into the trap,then thru the trap , then back up for 1/2(3") the length of the drop. Then the drain goes down hill after that .At this point we put in an open "T" for drainage, air out water in. Also, on the horizontal of the trap we put in a "clean-out T" , unscrew the pipe plug and clean out the trap. or 2- horizontal out of the AH, then a " T" with the "run "of the "T" being vertical. The bottom "run" goes down into the trap and the top part of the run goes up. That top "run" must be sealed or capped. After the trap all that water in the drain line just drains away, and junk/gunk/crap does accumulate in the drain line.
@ February 23, 2014 11:33 AM in geothermal vs. airsourceWith a 40* evap and 20* or so Freon temp then the following holds true ,I think. AC is 12,000btu/ton/evap/per horsepower, 5t=60k btu=5 HP comp motor.there is 15,000btus of heat rejection . Assumeing a 20* Freon temp then that changes the btu/ton/hp ratio. At 20* Freon temp, that turns into refrigeration , at 20*the btu per hp is about 9,000btu. 12,000btu is still one ton. This is from the comp mfrg , chart of suction press/evap temp range,vs btu, thing.
@ February 23, 2014 8:46 AM in geothermal vs. airsourceWith an evap temp of 40*f would that give a Freon temp of 20* ,inside the evap ?Like AC.
@ February 21, 2014 1:42 PM in geothermal vs. airsourceAcross the board, what is the lowest evap temps heat/cool that the refrigeration system/compressor will be subjected to?
@ February 19, 2014 9:44 PM in 007 capNow if you had the cap on board the truck ,that would be a win win.
@ February 19, 2014 9:37 PM in Tom Schwarz has passed awayI met and re-met Tom at ,at least 6-8 classes over the years. He always had a smile and a handshake. He was a good guy.
@ February 15, 2014 3:56 PM in 007 CAPThat was Riello using a light bulb . I believe most AC/R supply houses have/can get that cap
@ February 15, 2014 8:16 AM in Honeywell R8222k 1000 replaced with R8222N 1011...same issueWhat is the measured volts across the relay coil as the relay is energized? Is there a 2nd xformer?
@ February 15, 2014 7:58 AM in Replacement condenserThe HP was started in the heat mode so the indoor coil was acting as a condenser. Slight delay of the indoor fan? cover not on properly?
