(5) Thermal insulation for pipeline.
1) To avoid condensate or water leakage on connecting pipe, the gas pipe and liquid pipe
must be wrapped with thermal insulating material and adhesive pipe for insulation from
the air.
2) For heat pump unit, liquid pipe should bear 70
℃
(158
℉
) or above, and gas pipe should
bear 120
℃
(248
℉
) or above. For cooling only unit, both liquid pipe and gas pipe
should bear 70
℃
(158
℉
) or above. Example: Polyethylene foam can bear 120
℃
(248
℉
) above and foaming polyethylene can bear 100
℃
(212
℉
) above.
