Measuring Refrigerant Stress
Measuring refrigerant stress is a crucial step in charging a house AC system. The stress readings will enable you decide the quantity of refrigerant that must be added or faraway from the system. To measure the refrigerant stress, you will have a manifold gauge set. This set consists of two gauges, one for the high-pressure aspect and one for the low-pressure aspect, in addition to a set of hoses and a charging hose.
To measure the refrigerant stress, observe these steps:
1. Join the manifold gauge set to the AC system.
The high-pressure hose must be related to the service port on the high-pressure aspect of the system, and the low-pressure hose must be related to the service port on the low-pressure aspect. The charging hose must be related to the refrigerant tank.
2. Open the valves on the manifold gauge set.
This may permit the refrigerant to movement via the gauges. The high-pressure gauge will learn the stress on the high-pressure aspect of the system, and the low-pressure gauge will learn the stress on the low-pressure aspect.
3. Learn the stress readings.
The stress readings will differ relying on the kind of refrigerant getting used and the working circumstances of the system. Seek the advice of the producer’s specs for the right stress readings in your system.
4. Examine the stress readings to the goal pressures.
The goal pressures are the pressures that the system must be working at. If the stress readings usually are not throughout the goal vary, you will have so as to add or take away refrigerant from the system.
| Refrigerant | Goal Excessive-Stress (psi) | Goal Low-Stress (psi) |
|---|---|---|
