question for reversing valve

[mike davies]

hi can someone tell me what e means on a reversing valve and confirm with me this side runs to the condenser in cooling mode

[sedgy]

HI MIKE , is it a sticker on a pipe on the valve that sayes this pipe to cond, in cooling mode?

[mike davies]

well on the front of the 3x pipes starting from the left with the solenoid in front of you, you have [e] [s]for the most obvious then you have [c] on a sticker which is on the cylinder

Just checked with the Danfoss fitters notes and it says that it is easy to identify which is which. But - it isn't clear in the text, however the diagrams help no end. ;)

e s c - evaporator, suction-line, condenser maybe?

[Scramjetman]

:DIgnore that!

Hi Mike,

This might help.

e = evaporator
s = suction
c = condenser
D on the underside is discharge.

Danfoss Sheet link attached. Hope this helps.

Apologies to those that already know this but to make the valve easier to replace, cut it out away from the valve, transfer the pipes one by one, them braze back into unit. That way no need to try and get 3 pipes in at the same time.

Interesting article here on trobleshooting the valves.

I used to write a column called "TECH Check" for the ACH&R News back in the mid 80's. How time flies.

Damn, I'm old... lol

You have written for them recently though. One of your articles in more recent decades was about the importance of engineers understanding a little about how to control SHR.

We could improve on it - perhaps we should write another for them but submit it as a collaboration :)

[Gary]

I had forgotten about that article... yep, old... lol

Note that I stopped short of the level of complexity at which I would need to call it SHR. :)
