Checking Aircon

### Air Conditioning checking and Inspection

The regular inspection and maintenance of air conditioning units are crucial for ensuring their performance and extending their lifespan. Below is a summary of the main inspection items, methods, and precautions.

#### I. Inspection Items

1. **Cooling/Heating Effect**

   - Measure the difference between indoor temperature and the set temperature to evaluate the cooling and heating performance.

2. **Refrigerant**

   - Check the pressure and quantity of the refrigerant using a pressure gauge to measure both low and high-pressure sides.

3. **Filter**

   - Regularly clean or replace the filter to maintain airflow and ensure the efficiency of the air conditioning system.

4. **Evaporator and Condenser**

   - Clean the evaporator and condenser of dirt to ensure efficient heat exchange and check for any blockages.

5. **Fan and Motor**

   - Ensure the fan operates normally and is free from unusual noises; check the motor's heat dissipation.

6. **Drainage System**

   - Inspect the drainage hose and pump to ensure they are clear, preventing water buildup and leakage issues.

7. **Electrical Connections**

   - Check the safety of wires, plugs, and switches to ensure there are no risks of short circuits.

#### II. Inspection Methods

- **Visual Inspection**

  - Observe the condition of the unit, checking for any obvious faults or corrosion.

- **Pressure Testing**

  - Use a pressure gauge to check the refrigerant pressure in the system and confirm that it is within the normal range.

- **Temperature Measurement**

  - Use a thermometer to measure the temperatures at the inlet and outlet to evaluate the cooling and heating effectiveness.

- **Airflow Measurement**

  - Utilize an anemometer to measure the fan's airflow to ensure it meets standards.

#### III. Precautions

1. **Safety First**

   - Always disconnect the power supply before conducting any inspections to ensure safety.

2. **Regular Maintenance**

   - Conduct a comprehensive inspection and maintenance at least once a year to prevent failures.

3. **Refer to the Manual**

   - Read the air conditioner's user manual to understand the maintenance requirements specific to your model.

4. **Timely Fault Handling**

   - Address any unusual situations promptly to prevent worsening of issues.
