Theoretical Limit of Chiller Efficiency
The energy conservation in chiller exchangers are analyzed in this paper, the formula of limit of coefficient of performance (COP) is then deduced. According to the working condition of GB/T 18430.1—2007 and AHRI 550/590—2011, the limits of COP and IPLV are calculated for water cooled chiller and ai...

| description | The energy conservation in chiller exchangers are analyzed in this paper, the formula of limit of coefficient of performance (COP) is then deduced. According to the working condition of GB/T 18430.1—2007 and AHRI 550/590—2011, the limits of COP and IPLV are calculated for water cooled chiller and air cooled chiller respectively. The results show that, the COP limit and IPLV limit of water cooled chiller is 10.01/14.51 at GB/T 18430.1—2007 condition and 10.07/17.3 at AHRI 550/590—2011 condition. For air cooled chiller, those values are 7.37/10.25 and 7.30/16.11. The air temperature increase through condenser coil and the condensing temperature is decided by its heat transfer area and effectiveness. If the former temperature in full load at rated condition can’t be achieved to be less than 10℃ by means of improving coil configuration, enlarging heat transfer area and improving the heat transfer effectiveness, the limit of COP of air cooled chiller in full load will be no more than 7.37, IPLV can’t be higher than 10.25. |
