How to adjust uneven geothermal circuit
In recent years, with the popularization of geothermal energy utilization technology, geothermal heating systems have become more and more widely used in homes and commercial buildings. However, many users have reported that the geothermal circuit has temperature unevenness, which affects the overall heating effect. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the causes and adjustment methods of uneven geothermal circuits.
1. Common causes of uneven geothermal circuits
According to recent online discussions and expert analysis, the main reasons for uneven geothermal circuits include the following points:
| Reason | Proportion | Specific performance |
|---|---|---|
| The circuit length design is unreasonable | 35% | The length difference between each circuit is too large, resulting in hydraulic imbalance |
| clogged pipes | 25% | Impurity deposits in pipes affect water flow speed |
| Improperly adjusted water distributor | 20% | The valve openings of each circuit are inconsistent |
| Insufficient system pressure | 15% | The water pump power is insufficient or the system is leaking |
| other reasons | 5% | Including damage to the insulation layer, impact of ground coverings, etc. |
2. Adjustment method for uneven geothermal circuit
In response to the above problems, the solutions that have been hotly discussed on the Internet recently mainly include the following:
1.Hydraulic balance adjustment: This is the most effective way to solve loop unevenness. The specific steps are as follows:
| steps | Operation content | Things to note |
|---|---|---|
| first step | Close all circuit valves | Make sure the system is turned off |
| Step 2 | Open each circuit one by one | Record flow data of each loop |
| Step 3 | Adjust the manifold valve | Make the flow rate of each loop consistent |
| Step 4 | System operation test | Observe 24-hour temperature changes |
2.System cleaning: According to recent maintenance case statistics, about 60% of geothermal systems require professional cleaning after 3 years of operation. Recommended cleaning frequency is as follows:
| Service life | Recommended cleaning frequency |
|---|---|
| 1-3 years | Once every 2 years |
| 3-5 years | once a year |
| More than 5 years | 1-2 times a year |
3.System boost: If the system pressure is detected to be insufficient, the following options may be considered:
- Replace the circulation pump with a larger power one
- Check the system for leaks
- Increase expansion tank capacity
3. Related issues that have recently been hotly discussed on the Internet
According to network data analysis in the past 10 days, the geothermal-related issues that users are most concerned about are as follows:
| question | search volume | heat index |
|---|---|---|
| Energy saving methods for geothermal systems | 12,500 | 85 |
| Comparison between floor heating and radiators | 9,800 | 78 |
| Geothermal system maintenance costs | 7,600 | 72 |
| Intelligent geothermal control system | 6,300 | 68 |
4. Expert advice
Based on the recent opinions of many HVAC experts, it is recommended to take the following preventive measures for the problem of uneven geothermal circuits:
1. Select a professional design team at the initial stage of installation to ensure that the length difference of each loop does not exceed 10%
2. Carry out system inspection before the heating season every year
3. Use water treatment equipment to reduce pipeline scaling
4. Consider installing an intelligent water distributor to achieve automatic adjustment
As one of the most comfortable heating methods, geothermal systems require professional skills to maintain and adjust. If you encounter complex problems, it is recommended to contact professional maintenance personnel to deal with them. Do not disassemble important components by yourself to avoid causing greater losses.
