IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date: November 2010 Figure 11: Operation performance of the CoolCabin on the Aug. 23, 2009 The fraction of free cooling in the months July, August and September (2009) is shown in Figure 12 including detailed numbers in the tables below. Figure 12: Free cooling share of the total delivered cooling load for July, August and September 2009 Approximately one third of the total cooling load was done by free cooling. The free cooling mode is especially running in night times and on rainy days. 4.2.3 Improvements / changes 2009-2010 After the monitoring period 2009 some changes and improvements have been performed. The main changes were: • beginning of May10: Maintenance of the cooling tower • end of May10: o supply temperature of chilled ceiling from 17°C to 15°C o clearance temperature (upper storage temp.) for starting the ACM from 75°C to 88°C page 13
IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask A Report, Date: November 2010 • end of May10: o clearance temperature (upper storage temp.) for starting the ACM from 88°C to 80°C o Change of ventilation control strategy on/off to speed control The effects of these changes are shown in Figure 13. Figure 13: Comparison of thermal and electrical COPs 2009 and 2010 Compared to the cooling period 2009 (including free cooling and thermal driven chiller) the electrical COP was rising 36% up to value of 2.3 while the thermal COP was on the same level. After changes in the control parameters another increase of 44% could be achieved. Finally, including the change of the control strategy of the cooling tower fan, the electrical COP is at about 3.4. Compared to 2009 a plus of 105% in the electrical COP was obtained. The thermal COP mainly affected by the reccoling, regeneration and chilled water temperature level was enhanced by 17%. Main reasons for the better performance are higher loads due to weather conditions and changes in the set temperatures (supply temp.) and as a result less part load condition! 4.2.4 Cooling period 2010 The daily performance of a typical sunny day is shown in Figure 14. The chiller starts its operation at 11:30 a.m. after the storage temperature reaches 80°C. The driving temperature is slightly increasing during operation and the average is at about 77°C. The chilled water temperature decreases from 20°C to 8° C while the recooling temperature is controlled to 29°C. Within these conditions a decre asing power for driving heat and cold production is visible. page 14
