Never mind, figured it out. The data file is supposed to have the COP ratio not the part load COP.

Subject: Type666 Chiller exceeding peak capacity

I have setup a 30 ton chiller(Type666) with a 3 C set point. A lot of the time the chiller's capacity is insufficient to meet that set point. Instead of the temperature creeping up, the capacity is increased. The peak capacity I get in my run is 115 tons.

When I set the capacity to 1 kJ/hr, the chiller capacity output indicates approximately 4 kJ/hr. Is the capacity mislabeled as the peak power, and the COP is multiplied by the peak power to get the cooling capacity?

Can anyone shed some light on this?

Please advise,

Fred
