Hi everybody. i am new in this form. now i am in serious trouble. i hope some one in this form can help me out. i am working in a caribbean islands and we dont have much air conditioning guys here to help me out.
problem. i installed one used 40 ton water cooled unit and used 5H40 carrier compressor. this compressor i know it is good and i were uisng this compressor last six years with out any problem on other system. but now i am using R22 refrigerant and am getting 35 psi suction pressure and 150 psi discharge pressure. i know this unit is enough refrigerant and i am not feeling heat on the discharge side copper tubing too. . also i have good water flow throught the condensor and evaporator. also saw ice on the comprressor both side. what may causes low suction and low discharge pressure?. do you think it is because of TXV. ( TXV is came with this used unit). what i should do . i am having 82 F ambient temparature . so help me out
