Modulation is the process of varying one or more properties of a high-frequency periodic waveform or like when a thermostat sends a signel to a controller to make a change in a supply fan speed or a...

If you have unloaders they may be loaded up on the 3rd try and hanging up

I agree with CFC and remove about 20% on one unit and concentrate on working on it and see what you come up with. Another situation, at 120# your SST was about 34 *F so I suspect that you may have to...

Average KW/H of 25 ton Air Conditioning with R22
Heat load BTU/H KW/H EER SCT
1. 272,000 27.18 10 130
2.242,000 23,80 10.16 129
3.212,000 20.44 10.48 128
4.182,000 17.20 10.64 127...

T0 find the average I would have to take a series of loads lets say 10 and find an average and thats a lot of work but if I have the time I will see if I can do that any way i find this problem...

I am able to plot the KW/h with changing the load as I show below
I can tell you with 272,000BTU/h with R-22 the KW/h = 27.2 with 131*F SCT and 42*F SST, EER = 10
At 195,000 Btu/h, with R-22...

If we do it this way I get this
The gross btu = 300,000 btu/h and the net = 272,000 btu/h which is ~91% efficiency now if we find the btu/h we devide by 272,000 by 24Hours I get 11,333 btu/h and if...

I worked this out
EER = energy efficient ratio (Btu/Wh) there-for 10 EER = to 12/10 =1.2 btu/wh times 1000 W or 1 KW =1,200 BTU/H and for IEER=12/10.4=1.15 W/H x 1kw=1150 btu/h so lets split it to...

An ex-brother in law once ranted to me for an hour about why the labyrinthine Electoral College system was “totally screwed up to hell.” I’m not saying he’s right or wrong, but if he was right…he had...

Condenser approach should be 0-3 *F Check for some tube fouling
or low flo

Because I want to

For a 4 ton at 1600 CFM Supply = 18" and Return = 21" round per 100 ft at a friction rate of 0.1 wc with (2) 14" x 20" returns each at 800 CFM and 460 FPM

It's a sad thing to say but i believe your first and primary concern should be whats best for you always. When I was young i used to think that i owed a company I worked for my loyalty until I got...

Suction line needs to be 1-1/8" and liquid line needs to be 1/2" at that distance

Boy am I impressed!! I wonder what math formula "Bubba Joe" and "Billy Jack" used the figure how many crimps to make to get the right mass flow,,, Ya think it was trial and error????

OK Lets vote which explanation is most likely!!!!!!!!!!

That's the econimizer control sensor. Its operation is based on weather it's cloudy or sunny. if its cloudy then you get econimizer full on and if its sunny the econimizer is off and if its partly...
