CO2 Rack Inefficient in Hot Weather
High-side pressure and energy look high on a hot day — is it normal transcritical operation or a fault?
First step
Is the gas-cooler approach (outlet temperature minus ambient, or wet-bulb if adiabatic) within the system's design / commissioning value?
No — outlet temp is high
Yes — outlet is close to ambient
