Hi blazer.
a little bit more info is required for an informative comment.
1/ refrigerant 2/ operating pressures. 3/ application. 4/ compressor details. 5/ evaporator details. 6/ txv details.

1.r-22
2. Low 60psi, high 220psi
3.comfort

3.comfort cooling

4. 15 ton recip compressor,480 3phase 25 amp (two comps per evap)

5. all i know is 2 comps per evap

6. tev-15-ga (15ton)

evap heat load (btu / hr) = mass flow (lbs / hr) * latent heat of evap for r22 at evap press/temp (btu / lb)

take heat load (btu / hr) and divide by 12000 to get tonnage.

2x 15 ton compressors = 30 ton evaporator
