3) Drain hose

For easy drainage of the condensation water, the should be installed with a downward gradient. To avoid

the condensation, the connection pipe joint should be insulated with thermal insulation material. A water seal

should be employed as shown in Fig. 19 and the height of the water seal could be determined by the pressure of

the drain hose.

Drain hose is in negative pressure state: A = B P/10+20 (mm)

Drain hose is in positive pressure state: A 30mm,B P/10+20 (mm)

Note: P is the absolute pressure of the drain hose position, Pa

4) Refrigerant pipe insulation layer

To avoid condensation of drew and water leakage, gas pipe and liquid pipe of refrigerant should be insulated

with thermal insulation material and adhesive tape.
