Matching components in refrigeration system

Here are my specification calculated from software (theoretical conditions though)

Refrigerant : R22
Condensing Temp: 55 oC
Evaporating Temp: 5 oC
Heat Reject (in condenser) : 3.125 kW
Heat Absorbtion (in evap): 2.52 kW
Work (compressor) : 0.58 kW

Here are my questions

How can I choose compressor to meet the specifications. Compressor suppliers provide only kW -> If I choose 0.6 kW, will it be adequate? They also provide cooling load which does not equal to 2.52 kW. How can I be sure if it fits to the system? If it exceeds 2.52 kW, is it enough?

Thank you very much
