Condensate water occurred in Netcol8000-A

Publication Date:  2019-02-19 Views:  46 Downloads:  0
Issue Description

In one project , air conditioner pipes generate a lot of condensate water in the following places :


1- Thermal insulation pipes cracks as well as connectors and handles without thermal insulation foam.


2- Where the clearance between pipes in sufficient.


3- Where the thickness of thermal insulation pipes is insufficient 


Alarm Information

Air conditioner pipes generate a lot of  condensate water .


Handling Process

1- Rewarp the thermal insualtion pipes & ensure that there is no crack.


2- Seciure the air conditioner pipes and reserve a proper clearance between pipes.


3- Select Thermal insulation pipes with a proper thickness based on environmental conditions & rewarp the pipes.

Root Cause

The temp , humidity and dew point of the equipment room are 23C , 80% and 19C respectivelly . The water supple temp. of chilled water A/C is generally within 7--10 C , which air far lower than the dew point.

If the chilled water pipes are not well thermal insulated and air around the pipes is not ventilled , the temp. on the pipes exterior will be lower than the air dew point . resulting in condensation .

Solution

1- Rewarp the thermal insualtion pipes & ensure that there is no crack.


2- Seciure the air conditioner pipes and reserve a proper clearance between pipes.


3- Select Thermal insulation pipes with a proper thickness based on environmental conditions & rewarp the pipes.

Suggestions

1- Directly enclose the chilled water pipes with thermal insulation pipes.

Avoid cutting open the thermal insulation pipes , wrapping the chilled wated pipes with them and then applying glue.


2- Well plan the pipes routing and support position so that a proper clearance between pipes can be reserved and pipes can be secured .
