Why the Chilled Water Air Handling Unit (AHU) Needs to Be Used in Conjunction with a Chiller:

 

1. Supply of Chilled Water:
We have chilled water air handling unit and assembly (modular ) air handling unit , OEM welcome , can add heat recovery and other special technical requirements . The chilled water AHU is connected to the chiller via chilled water coils. The chiller's role is to cool the water to a set temperature, and then circulate the chilled water into the AHU. Inside the AHU, the coils exchange heat with the air, rapidly lowering the temperature of the air passing through, thus cooling the space.

 

2. The Role of the Chiller:
The main function of the chiller is to cool the water to a low temperature (typically between 4-7°C) and then transport the chilled water to various air conditioning units such as the chilled water AHU, fan coil units, and air handling units. In this system, the chiller and chilled water AHU work together, exchanging heat effectively to regulate both temperature and humidity within the indoor environment. Notably, Guangdong Head-Power Air-Conditioning Co., Ltd. also offers a solution using a solution-type chiller. This allows the chiller to produce ice during off-peak hours (typically at night), when electricity demand is low. The frozen ice stores energy, which, when it melts during the day, provides chilled water, similar to a "battery" storing energy, thus reducing energy consumption.

 

3. Enhancing Energy Efficiency and System Stability:
Chillers typically have a strong cooling capacity and can intelligently adjust their operation based on load fluctuations, ensuring stable system performance. When paired with a chilled water AHU, this combination enables the air conditioning system to maintain high efficiency and long-term stable temperature control in large buildings or industrial sites, ensuring a consistently comfortable indoor environment.
