How to configure multi-line branch pipes
As a key component of the central air-conditioning system, the multi-line branch pipe configuration directly affects the operating efficiency and stability of the system. This article will combine the hot topics and hot content on the entire network in the past 10 days, introduce in detail the configuration method of multi-line branch pipes, and provide structured data for reference.
1. Function and selection of branch pipes
The branch pipe is a component used to divert refrigerant in a multi-split system. Its selection needs to be determined based on the refrigerant flow rate, pipe diameter and system capacity. The following is a reference table for selection of common branch pipes:
| Branch pipe model | Applicable pipe diameter (mm) | Maximum cooling capacity (kW) |
|---|---|---|
| FQ-01 | Φ6.35-Φ9.52 | 8 |
| FQ-02 | Φ9.52-Φ12.7 | 12 |
| FQ-03 | Φ12.7-Φ15.88 | 18 |
2. Installation points of branch pipes
1.Horizontal installation: The branch pipe needs to be installed horizontally to avoid uneven distribution of refrigerant due to tilt.
2.distance requirement: The distance between the branch pipe and the indoor unit should be greater than 500mm to reduce airflow noise.
3.Insulation treatment: The branch pipe and its connecting pipes must be well insulated to prevent condensation.
3. Configuration steps of branch pipes
1.Determine system capacity: Select the appropriate branch pipe model based on the total cooling capacity of the indoor unit.
2.Calculate pipe diameter: Refer to the refrigerant flow table to ensure that the pipe diameter matches the branch pipe.
3.layout design: Reasonably plan the location of branch pipes to reduce pipe elbows and reduce pressure loss.
4. Frequently Asked Questions and Solutions
The following are hot issues that users are concerned about and their solutions:
| question | Reason | solution |
|---|---|---|
| Poor cooling effect | The branch pipe selection is too small | Replace the branch pipe with a larger capacity |
| The system is noisy | Branch pipe installation tilt | Relevel |
| Condensation in pipes | Damaged insulation | Repair or replace insulation |
5. Analysis of hot topics across the entire network
In the past 10 days, discussions on multi-line branch pipes have mainly focused on the following aspects:
1.Energy saving optimization: How to reduce system energy consumption through branch pipe configuration.
