By qualitatively analyzing factors affecting the refrigerating capacity of absorption heat pumps

the test method to determine the refrigerating capacity correction curve was put forward. Applying this method on a 300MW unit

the correction coefficient of heat pump's boundary parameters on its refrigerating capacity were tested and calculated

and the quantitative data affecting the refrigerating capacity were first given.The results show that

regarding the condition that each parameter deviated from the design value in 10% as the judging condition

the sequence of parameters affecting the refrigerating capacity(according to the influence degree

from large to small)was:water temperature at the heat net inlet

water temperature at the heat source inlet

the driving steam pressure

the heating water flow

the water flow in heat source

the driving steam superheat.
