Summary

The objective of the present study is to investigate the efficiency of indirect adiabatic chiller-based cooling system efficiency dependence on outdoor air humidity. The system is located in a historical building, in the temperate climate of Latvia. The data about electricity consumption, water consumption, chiller operation stages, average cooling temperatures, and outdoor air parameters have been acquired for the period of 2,5 months, 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 on outdoor air humidity. Data range for the period from 1st August till 13th of October, year 2011 was taken for deeper analysis, which showed that in the 22.0±0.5°C temperature range for the studied period of time chiller’s COP is slightly dependent on outdoor air moisture.
