What fluorine is added to the excavator air conditioner? Comprehensive analysis and operation guide
With the arrival of high temperatures in summer, the refrigeration effect of the excavator air conditioner has become the focus of attention of the owner and operator. The selection and addition of air conditioning refrigerant (fluorine) is directly related to the user experience of the equipment. This article will combine the popular topics on the entire network for the past 10 days to explain in detail what fluorine is added to the excavator air conditioner, how to operate and precautions.
1. Types of commonly used refrigerant for excavator air conditioners
Currently, the mainstream refrigerant models and characteristics on the market are shown in the following table:
| Refrigerant type | Applicable models | Environmental protection | Market price (yuan/kg) |
|---|---|---|---|
| R134a | Most excavators produced after 2010 | No ozone damage, low greenhouse effect | 80-120 |
| R22 (phased out) | Old model excavator | Destroy the ozone layer | 50-80 |
| R404A | Some large-scale engineering machinery | High GWP value | 150-200 |
2. How to choose refrigerant correctly?
1.Check the device nameplate: The excavator cab or engine compartment usually has refrigerant markings, so the original designated model is preferred.
2.Pay attention to environmental protection regulations: According to the latest environmental protection requirements in 2023, refrigerants such as R22 that destroy the ozone layer have been banned from being used in new equipment.
3.Performance comparison: Although the new refrigerant R513A and other products are relatively expensive, their energy efficiency ratio is increased by about 15%, making it more economical to use for a long time.
3. Detailed explanation of the operation steps of fluoride addition
| step | Operation content | Things to note |
|---|---|---|
| 1 | System leak detection | Use an electronic leak detector to check the pipeline |
| 2 | Vacuum | Keep it for more than 30 minutes, vacuum degree ≤-100kPa |
| 3 | Fill in freezer oil | Add POE or PAG oil according to the compressor requirements |
| 4 | Quantitative addition of fluorine | Use electronic scale to control the filling volume |
4. Top 5 Popular Issues in 2023
According to the search data statistics of the entire network, the most popular excavator air conditioning issues recently:
1. Can different brands of excavators use refrigerant mixed? (32%)
2. Analysis of the reasons for the poor refrigeration effect after fluorine addition (25%)
3. Is it feasible to make homemade fluoride tools? (18%)
4. Actual use effect of environmentally friendly refrigerant (accounting for 15%)
5. Does special maintenance require in winter (10% of the proportion)
5. Professional maintenance suggestions
1.Regular maintenance: It is recommended to check the air conditioning system every 500 working hours, including condenser cleaning, belt tightness adjustment, etc.
2.Fault warning: It should be repaired immediately when the following situations occur: - The temperature difference of the air outlet is <8℃ - Compressor abnormal noise - System pressure abnormality
3.Safe operation: Protective gloves and goggles must be worn when adding fluoride. It is prohibited to open the maintenance valve when the system is high-pressure.
6. Comparison of mainstream brand services in the market
| brand | Original refrigerant price | Official fluoride addition service fee | Quality Assurance Policy |
|---|---|---|---|
| Caterpillar | 200 yuan/can | 300-500 yuan | 6 months |
| Komatsu | RMB 180/can | RMB 280-450 | 3 months |
| Trinity | RMB 150/can | RMB 200-350 | 12 months |
Summary: Fluorination of excavator air conditioners requires selecting the appropriate refrigerant according to the equipment model, and it is recommended that professionals operate it. Regular maintenance not only ensures the cooling effect, but also extends the service life of the system. If you need to operate on your own, be sure to strictly follow safety regulations.
