Happy Merry Christmas,

We would like to send our heartfelt thanks to all our clients, to the people of Cambodia, and those across the globe. May this Christmas bring everyone safe travels and good health.

May peace be with all those suffering from war around the world. May this season bring you warmth and time with the people who matter most.

How a Plate Heat Exchanger Works

The setup is to save energy through a process called Chiller Heat Recovery (or Heat Reclaim). The idea is to use a Plate Heat Exchanger (PHE) to capture waste heat from a building’s cooling system (the chiller) and reuse it to preheat hot water for things like showers or taps in hotels.

Essentially, it converts waste heat into free hot water.

1. Chiller Heat Rejection

 Usually, a chiller cools the building by absorbing heat from the chilled water inside and then dumping that unwanted heat into the condenser water loop. This hot water usually goes to a cooling tower, where the heat is released into the air, basically wasted.

2. Heat Interception

 In a heat recovery system, instead of discarding all the heat, we redirect some of the warm condenser water (which can be around 85°F to 110°F or higher) before it reaches the cooling tower.

3. Using the Plate Heat Exchanger (PHE)

 The hot water flows through one side of the PHE. On the other hand, cold city water (which is for the building) flows through. The two water streams never mix, but heat easily passes between them through the metal plates inside the exchanger.

4. Heat Transfer

As the hot condenser water flows through, it transfers its heat to the cold water, raising its temperature (for example, from 60°F up to 90°F or more). The condenser water is slightly cooler, while the domestic water is somewhat warmer.

5. Boiler Boost

 That preheated water then enters the boiler or water heater, which only needs to heat it the rest of the way, perhaps from 90°F to 140°F. Since the water is already warm, the boiler doesn’t have to work as hard or use as much energy.

Why This Is Great

* Energy Savings:

 The system recovers heat that would otherwise be wasted, allowing both the cooling and hot water systems to operate more efficiently.

* Reduced Boiler Load:

 Because the boiler is doing less heating, it uses less gas or electricity.

* “Free” Hot Water:

 The chiller provides heat as a natural part of cooling the building, so you’re basically getting hot water at little to no extra cost.

3 Critical Steps to Keep Your System Running Smoothly – Master Maintenance & Troubleshoot Like a Pro!

1. System Balancing and Checking

* Test the system to make sure it’s working as it should.

* Look out for leaks, like refrigerant or pipe leaks.

* Check the flow rate and pressure. If something’s off, adjust the valves by turning the screw until the readings are correct.

2. Training and Handover

* Make sure your team knows how to operate the system properly.

* Train them on both the manual and automatic controls.

* Teach them how to read alarm codes, warning signals, and how to use a maintenance checklist to keep track of the system settings.

3. Optimising and Monitoring Efficiency

* Approach Coefficient Analysis:

Keep an eye on the Condenser and Evaporator Approach Coefficients to make sure dirt or scale isn’t building up.

* Control Checks:

Regularly check the cooling tower fan speed, which is usually controlled by the condenser water temperature sensor. Lowering the condenser water temperature can help reduce the compressor's load, making the system more efficient.

* Load Management:

Ensure your system utilises Variable Speed Drive (VSD) control. This helps adjust pump speed based on the load, saving energy and improving overall efficiency.

How a Chiller System Works

Running a chiller isn’t just about keeping things cool; it’s about doing it efficiently and automatically. Here’s what that really means

Automatic Mode

- With today’s technology, you don’t need to adjust it every single time; one manual adjustment and it’s all set. Leaving it to automation, the system adjusts itself based on cooling needs.

Remote Control via BMS

The Building Management System is your robot assistant. Please turn it on, check performance, or fix it right from where you sit.

Seamless Integration

- The chiller talks to other systems like pumps and air handlers, so everything runs smoothly together.

Optimal Performance

- Smart sensors help the system deliver the right amount of cooling without wasting energy.

Efficiency

- When everything works in sync, you get the same cooling but use less power, saving money, energy, and time.
