3.5.3 Routing Refrigerant Pipes
Routing refrigerant pipes
To minimize the noise due to vibration, perform the following operations:
●
When the direction of the refrigerant pipe is changed, add a support at the
position that is 500 mm away from the changing point.
●
When the refrigerant pipe is straight, add a support every 1500 mm.
NO TE
Onsite personnel prepare the required materials and install the supports.
Figure 3-35 Routing the refrigerant pipe (unit: mm)
When selecting the refrigerant pipes, note the following:
1. Avoid elbows and ensure that the indoor unit and the outdoor unit are
connected by using shortest pipes.
2. Calculate the number of the components that cause local resistance loss, for
example, elbows, and convert them into the equivalent length to straight
pipes.
