Chiller Approach And Condenser Approach in HVAC System - Chiller Approach is a very important parameter in an HVAC system.
It is used to measure the performance of the chiller and its heat transfer efficiency.
Normal Value
Air Cooled Chiller: 5Β°F to 10Β°F (β‰ˆ 2.7Β°C to 5.5Β°C)
Water Cooled Chiller: 3Β°F to 7Β°F (β‰ˆ 1.7Β°C to 3.9Β°C)
Importance
1. Fouling Indication – High approach indicates evaporator tubes may be dirty or scaled.
2. Performance Monitoring – Regular checking of the approach gives an idea of chiller health..d. Properly.
3. Performance Monitoring – Regular checking of the approach gives an idea of chiller health.
Scaling / Fouling / Oil film in the evaporator.
Low refrigerant charge (gas shortage).
Poor water quality.
Refrigerant flow restriction.
Why is the Condenser Approach measured?fect.
Why is Condenser Approach measured?
1. It indicates heat transfer efficiency.
2. To assess the performance of the condenser in a chiller.
3. If the approach is high, it means the condenser is not rejecting heat properly.
4. It is very important for preventive maintenance and energy saving.
Normal Value of Condenser Approach
Normally considered 0.5Β°C to 1.5Β°C (under design conditions).
If it goes above 2Β°C, there may be some issue with the condenser.
Causes of High Condenser Approach
If the condenser approach is higher than 2Β°C, possible reasons are:
1. Fouling/Scaling – Dirt or scale deposition on condenser tubes.
2. Insufficient Water Flow – Inadequate flow from the cooling tower or pump.
3. High Condenser Load – Excessive heat rejection.
4. Air Pockets – Air trapped inside the condenser.
5. Tube Corrosion/Damage – Poor condition of condenser tubes.
Low Condenser Approach If the approach is very low (below 0.5Β°C), it is also an abnormal condition. This may be due to a sensor calibration error or measuring mistake.

Pump-Motor Shaft Alignment Procedure -: Pump and motor shaft alignment ensures the rotational axes of the pump and motor are perfectly aligned, preventing excessive wear and vibration.
A. Detailed Steps:
1. Prepare the Equipment: Ensure the pump and motor are properly supported and the coupling is accessible. Clean the coupling faces and remove any debris.
2. Prepare the Equipment: Ensure the pump and motor are properly supported, and the coupling is accessible. Clean the coupling faces and remove any debris.
3. Measure Misalignment: Use a chosen alignment method (e.g., dial indicators, laser alignment) to measure the initial misalignment.
4. Make Adjustments: Adjust the position of the pump or motor by shimming, moving the motor, or using jackscrews.
5. Re-measure and Verify: After adjustments, re-measure the alignment to ensure it is within acceptable tolerances.
6. Secure the Coupling: Once the alignment is verified, securely tighten the coupling bolts.
B. Methods of Measurement:
1. Dial Indicators: Dial indicators are used to measure radial and axial movement of the shafts, requiring mounting on the pump and motor shafts.
2. Laser Alignment: Laser alignment systems use lasers and sensors to precisely measure alignment, providing guidance on how to relocate and position the motor.
3. Straight Edge Alignment: This method involves placing a straight edge across the coupling faces to check for parallelism.
4. Rim-Face Dial Indicator Alignment: This method involves using dial indicators mounted on the coupling faces to measure alignment.
C. Important Considerations:
1. Thermal Expansion: Alignment should be verified after the machinery has operated under normal conditions, as thermal expansion can cause components to misalign.
2. Coupling Type: Rigid couplings require more precise alignment than flexible couplings.
3. Sequence of Adjustments: When using laser alignment, the order of adjustments (vertical, horizontal, and angular alignment) is important to avoid re-work.
4. Soft Foot: Correcting soft foot is a crucial step in the alignment process to ensure proper support of the pump and motor.
