Hi Everyone
I'm having a closed system A/C unit HPAC, I mean the air conditioner for technological applications such as data centers etc. The unit is working with R410A but the compressor is dead and such a compressor works with R410A isn't available, so I'm going to convert this unit to work with R22, will bring compressor with same capacity works with R22 and will bring Expansion valve also work with R22, but am wondering what the ratio between the capacity of the compressor and the expansion valve?, I mean if I have compressor 7 TOR what the size of expansion valve should I bring, I mean how many TOR?

Looking forward to hear from you soon.

Warm Regards
