nice bro this video more helps to me understand the york chiller because my site also same type york chiller pls continuously upload more video about acmv systems
Where do you top up the gas? And how long once need to top up?? At what pressure need to do?! Previously any issue you resolved that has leaking in chiller like that??
Hi @mohhamed in the video I mentioned evaporator service port at 13:39 you can check the pressure levels..and u can use the same port to top up the gas also... Actually when there is no problem in the system,we no need to top up the gas...some systems may get some internal gas leaks.. during that time we can topup the gas.. During your maintenance if the pressure levels are ok..or with in the range..u no need to top-up .. Pressure levels are for R134A is suction side 40 psi max discharge side 120 psi max..u can convert it into kpa if you want.. I faced a leak issue after annual shutdown at the filter drier side...then we rectified it .
