Note :
1.High temperature working condition is +40/+5℃,moderate temperature working condition is+40/-10°℃,low temperature working condition is+40/- 35℃;the corresponding high temperature working condition of R507A is+40/+0℃;
With economizer,the liquid outlet temperature is 5℃higher than the saturation temperature of the air make-up pressure.The coling water inlet temperature of the oil cooler is+33℃,and the temperature difference between the inlet and outlet water is 5℃ .
2.*For series LG20S,the motor power is 3kW when used in R507A.
