| Abstract: | An experiment of using thermostatic expansion valve and open line as a throttle apparatus of an air cooled heat pump chiller during defrosting cycle was performed.By comparing the results of the experiment,it is found that using open line as a throttle apparatus during defrosting cycle,the performance of the unit is better than that of using thermostatic expansion valve. |
| Keywords: | air cooled heat pump chiller defrosting thermostatic expansion valve |
