Frequently Asked Questions (FAQs)
1. What size is the suction line on an air conditioner?
The suction line diameter for air conditioners can vary depending on the size and efficiency of the system. It can be 3/4, 7/8, or 1 1/8 inches in diameter.
2. What happens if suction line is too big?
If the suction line is oversized, it can cause issues with the return of oil to the compressor. On the other hand, if the suction line is undersized, it may result in a loss of capacity and an increase in superheat.
3. What happens if you don't vacuum in AC line?
Not vacuuming the AC system, especially after installation or service, can lead to suboptimal performance. When the system is exposed to the atmosphere, elements like air, humidity, and moisture can accumulate, affecting its efficiency.
4. How do you control the suction pressure on a compressor?
Suction pressure on a compressor can be controlled through speed control, which adjusts the compressor capacity and power by changing the stroke speed. Suction throttling is another method that reduces the suction pressure, but it also decreases the compressor's efficiency, capacity, and power.
5. How do you check suction valves on a compressor?
To check the suction valves on a compressor, start by turning off the compressor and installing a low-side pressure gauge onto the suction service valve. Front seat the suction service valve and then turn on the compressor. Within a minute or so, the low-side gauge should read at least a 20-inch vacuum.
