Hi All.... please give some info to me about expansion valve,i'll change TXV from 3TR to 5TR...is the compressor change too?...thank's

Why do you change it? Is there happen an high superheat?
OK with the new TXV the evaporator will give more capacity and the suction pressure will increase and the compressor will balance with the evaporator. No need to change it unless the compressor would work out of its limits.
