    Abstract: A method of evaluating performance of a chiller is provided. The method includes detecting a plurality of operating parameters of the chiller with a plurality of sensors. The method also includes individually determining a first coefficient of performance degradation due to condenser fouling. The method further includes individually determining a second coefficient of performance degradation due to condenser water flow reduction. The method yet further includes individually determining a third coefficient of performance degradation due to evaporator fouling. The method also includes determining a total coefficient of performance degradation of the chiller with a summation of the first, second and third coefficient of performance degradations.

    Abstract: A method of conditioning an environment includes generating, by a group feedback analysis system, a first comfort limit based on a first plurality of data points corresponding to user feedback of a group of users in an environment conditioned by an environmental conditioning system, and each associated with temperature and humidity environmental criterions. The method further includes generating a second comfort limit based on a second plurality of data points corresponding to user feedback of the group of users, and associated with the temperature and humidity environmental criterions. The method identifies a constrained comfort zone defined by the first comfort limit, the second comfort limit, predefined lower and upper bounds for the temperature environmental criterion, and predefined lower and upper bounds for the humidity environmental criterion. The environmental system is controlled to maintain the temperature and humidity environmental criterions within the constrained comfort zone.
