Re: york chiller efficiency
Chiller efficiency does mean chiller energy efficiency. Calculate the chiller actual capacity and check how much electricity is consumed to get this output.COP is term of to find out the chiller efficiency. To calculate the chiller capacity finds this formula.
GPM*DELTA T/24.
To find out the COP
Actual thermal kilowatt of chiller divided by electrical input of chiller (thermal kilo watt/electrical input). higher cop means higher efficient of chiller.

Re: york chiller efficiency
That's (US gpm)*(°F delta T) / (24) = tons of cooling.
(Tons)*(12,000) / (3412) = kW of cooling
kW of cooling / kW of electrical input = COP
