Whether you are a homeowner looking to comprehend your cooling system better or an aspiring HVAC technician, this article will serve as a comprehensive guide to the air conditioner throttle.
The throttle valve is one of the most important parts of the air conditioner. This valve is directly involved in the generation of cold air in the cold unit of the air conditioner. To learn more about the throttle, let’s find out with Tnhelearning.edu.vn through the article below!
What is an air conditioner throttle?
Refrigeration throttle is a type of valve used in the refrigeration system of an air conditioner. The main job of the throttle valve is to transport gas from the liquid state to the vapor state to provide cold vapor that creates cool air inside your room.
In fact, the air conditioners used in the home will often use capillary tubes . This is also a type of throttle valve, but the difference between the capillary tube and the throttle valve is that the gas flow adjustment cannot be changed automatically but must depend on the diameter of the pipe.
Air conditioner throttle structure
Refrigeration throttle valve structure includes the following parts:
| part name | Mission |
| Heat sensor bulb | Sensing and adjusting the system automatically to suit the needs of the user. |
| Capillary tube | The pipe has a length of about 0.5 – 5m , a diameter of about 0.6 – 2mm . It has the function of transferring substances and vapors out, and at the same time keeping the gas flow constant. |
| Folding screen | Prevent gas from escaping. |
| injector | Allows the tip of the air conditioner throttle to blow cool air to the outside. |
| Saving to the indoor unit | Adjust the speed and working temperature of the valve. |
| Cap | Close it to prevent steam from escaping. |
| Adjustment screw | Used to adjust the working pressure of the valve. |
| Valve spring | The valve head position will receive the gas pressure pushed out by the spring. |
| Fluid from the high-pressure reservoir to | Used to store the pressure to the pressure most suitable for the valve. |
| Filters | Filter the liquid and convert it to a gas. |
| Ty van | High-grade stainless steel, plays the role of controlling the opening and closing process of the valve. |
| Diaphragm | The part that prevents the gas from escaping. |
Working principle of air conditioner throttle valve
| Operation steps | Contents of the steps |
| Step 1 | The gas will have low pressure , and low temperature after passing through the throttle valve. |
| Step 2 | After reaching the indoor unit, the gas will absorb heat from the surrounding environment. Then the air in the room will be sucked by the fan to pass through the indoor unit to cool and then return to the room. |
| Step 3 | The heat-carrying gas will be brought to the compressor and compressed to a high pressure level. |
| Step 4 | Gas at high temperature and pressure is brought to the outdoor unit for cooling. |
| Step 5 | The gas will continue to be brought to the throttle valve to reduce the pressure and temperature then start a new cycle of operation. |
Signs of a broken throttle valve and how to fix it
Recognizing signs
When your air conditioner shows the following signs, it means that the throttle valve of the machine is clogged and needs to be fixed immediately to avoid affecting the efficiency as well as the life of the air conditioner:
- The air conditioner is not cold or the cooling is very weak.
- Air conditioner leaks water in the indoor unit.
- The machine is stuck with snow on the indoor unit, or on the copper pipe.
- The air conditioner runs and stops continuously.
- The fan in the outdoor unit is not hot.
- The flow increases, the discharge pressure increases.
How to fix
In case the throttle valve is blocked, you need to conduct an inspection to thoroughly determine the cause, identify the telltale signs to give the fastest treatment directions.
Usually, the most common and fastest solution is to replace the new throttle valve for the air conditioner, because when the valve is blocked, it will not be able to completely fix it.
Above is an article that provides information about air conditioning throttle, structure, use as well as when the throttle is blocked, how to fix it. If you have any further questions, please leave a comment below for a timely response!
In conclusion, an air conditioner throttle, also known as an air conditioning expansion valve, is a crucial component of the air conditioning system. Its primary function is to regulate the flow of refrigerant flowing into the evaporator coil, allowing for efficient cooling. This valve operates by adjusting the amount of refrigerant entering the evaporator coil based on the cooling needs of the space.
The structure of an air conditioner throttle typically consists of a small diaphragm, a needle valve, and a sensing bulb. The diaphragm senses the pressure and temperature in the evaporator coil, while the needle valve regulates the flow of refrigerant accordingly. The sensing bulb monitors the temperature of the refrigerant leaving the evaporator coil, providing feedback to the valve to maintain the desired cooling level.
The use of an air conditioner throttle is vital for optimal cooling performance. By modulating the flow of refrigerant, it ensures that the evaporator coil is neither flooded nor starved. This allows the system to effectively remove heat from the air and maintain the desired temperature in the space. Without a properly functioning throttle, the air conditioner may struggle to cool the room adequately, leading to discomfort and reduced energy efficiency.
When an air conditioner throttle gets clogged, it can have detrimental effects on the overall performance of the system. A clogged throttle can result in poor cooling, increased energy consumption, and potential damage to other components. To fix a clogged throttle, it is advisable to seek professional assistance. They can identify the underlying cause of the clog, whether it be debris or refrigerant leakage, and take appropriate measures to rectify the issue. Regular maintenance, such as cleaning or replacing filters, can also prevent clogging and ensure the smooth functioning of the throttle.
In conclusion, an air conditioner throttle plays a key role in regulating refrigerant flow for efficient cooling. Understanding its structure, function, and importance allows users to recognize the significance of maintaining this component. By addressing clogs or other issues promptly, individuals can ensure their air conditioning system operates optimally, providing comfort and energy efficiency.
