The objective of the present study is to investigate the efficiency of indirect adiabatic chiller-based cooling system efficiency dependence of outdoor air humidity. The system is located in historical building, in temperate climate of Latvia. The data about electricity consumption, water consumption, chiller operation stages, cooling average temperatures and outdoor air parameters have been acquired for the period of 2.5 month, during the cooling season. Using data collected by BACnet based BMS controllers and adiabatic chiller control system, we have analyzed operation efficiency of the chiller and its dependence of outdoor air humidity. Data range for the period from August 1st till October 13th, 2011 was taken for deeper analysis, which showed that in temperature range 22.0 ± 0.5 °C for the studied period of time chiller’s COP is slightly dependent on the outdoor air moisture.
