22kW of CPU heat would need 22kW of cooling. Refrigerated air conditioning is has about 1:3 thermal efficiency, so your cooling system will require ~7.5kW electricity to generate 22kW cooling capacity.
That makes about 30kW. At $0.15 / kWh we're talking about $4.5 per hour for the electricity.

Other costs dwarf the energy costs.
