expansion valve
Hi guys,
We have air handling unit (A/C system) and a thermostatic expansion valve.
We have to fasten thermostatic bulb of expansion valve on suction pipe or should put bulb in drift of DX coil air outlet ?
Which one is correct ?
Thanks.

Re: expansion valve
The bulb should be fastened to the suction pipe in accordance with the manufacturers instructions.

Re: expansion valve
It should be fixed on the suction line and has to be insulated so as to operate on right super heat
