During normal operation, the refrigerant absorbs heat from the air inside the evaporator coil, causing it to evaporate and turn into a gas. This gas is then compressed by the compressor, which increases its temperature and pressure. The high-pressure, high-temperature gas then flows through the condenser coil, where it releases heat to the surrounding air and turns back into a liquid.
When the refrigerant needs to be pumped back into the condenser, several steps need to be followed. These steps ensure that the process is done correctly and that the refrigeration system operates efficiently.
| Step | Description |
|---|---|
| 1 | Prepare the refrigerant pump by checking its condition and ensuring it is clean and free of any debris. |
| 2 | Connect the pump to the condenser coil using the appropriate hoses and fittings. |
| 3 | Open the valves on both the pump and the condenser to allow the refrigerant to flow. |
| 4 | Monitor the pressure gauges to ensure that the refrigerant is flowing at the correct rate and pressure. |
| 5 | Once the desired amount of refrigerant has been pumped into the condenser, close the valves and disconnect the pump. |
