Building my first Single Stage

Can you give the high and low side pressures? I would like to know the pressures you were getting before using the chiller on the desuperheater. Such high pressures on high side with somewhat high temps on evap and frost on compressor suction return has me wondering about the valveplate in the compressor.

Its difficult to measure low pressure atm but what makes you think that there is problem with valveplate? When I cooled enough the refridgerant at 175-180psi the evaporator temps are better (-47.5 C) that means low side pressure at 0psi and below I think.
