How to use the refrigerant table
The refrigerant meter is a commonly used tool in the refrigeration industry, used to detect and record the status of the refrigerant (refrigerant) in the refrigeration system. Proper use of the refrigerant meter can help technicians quickly diagnose problems with the refrigeration system and ensure efficient operation of the equipment. This article will introduce in detail how to use the refrigerant table, and provide you with a practical operation guide based on the hot topics and hot content on the Internet in the past 10 days.
1. Basic components of the refrigerant table

The refrigerant type table usually consists of the following parts:
| Part name | Function description |
|---|---|
| High voltage meter | For measuring the high side pressure of refrigeration systems |
| Low pressure gauge | For measuring low-pressure side pressure of refrigeration systems |
| middle hose | Service valve connected to refrigeration system |
| temperature scale | Displays the refrigerant temperature corresponding to the pressure |
2. Steps for using the refrigerant table
1.Preparation: Make sure the refrigeration system is turned off and wear protective gloves and goggles.
2.Connect refrigerant table: Connect the hoses of the high-pressure gauge and low-pressure gauge to the high-pressure side and low-pressure side service valves of the refrigeration system respectively.
3.Start the system: Turn on the refrigeration system and observe changes in the pressure gauge reading.
4.Record data: Based on the readings of the high-pressure gauge and low-pressure gauge, combined with the temperature scale, determine whether the refrigerant is in normal condition.
5.Analyze the problem: If the pressure is abnormal, it may mean insufficient refrigerant, system blockage or leakage, etc.
3. The correlation between the hot topics on the Internet in the past 10 days and the refrigerant list
Recently, hot topics in the refrigeration industry have mainly focused on energy conservation, environmental protection and intelligent detection technology. The following are relevant hot topics:
| hot topics | Association with refrigerant table |
|---|---|
| Environmentally friendly alternative to refrigerants | The refrigerant meter can be used to detect the pressure status of new environmentally friendly refrigerants |
| Intelligent refrigeration equipment | Some new refrigerant meters have integrated digital functions and support remote monitoring. |
| Refrigeration system energy saving optimization | Detect pressure through the refrigerant gauge to optimize the operating efficiency of the refrigeration system |
4. Common problems and solutions
1.Pressure gauge reading is unstable: There may be air or insufficient refrigerant in the system. It is recommended to refill the refrigerant after vacuuming.
2.High pressure side pressure is too high: Check whether the condenser is dirty or blocked or has poor heat dissipation. Clean or replace it if necessary.
3.Low pressure side pressure is too low: It may be a refrigerant leak or expansion valve failure, which requires further investigation.
5. Summary
The refrigerant type meter is an indispensable tool in refrigeration maintenance. Correct use of it can greatly improve work efficiency and diagnostic accuracy. Combined with current industry hot spots, refrigerant meters may become more intelligent in the future, providing more convenience for the maintenance and optimization of refrigeration systems. I hope this article can help you better understand and use the refrigerant table.
