If chilled water is not used in air conditioners (ACs) that rely on a chilled water system, the cooling function of the AC will be severely affected or completely compromised. Chilled water is an integral part of the cooling process in certain types of AC systems, particularly in larger commercial or industrial setups.
In a chilled water system, chilled water is typically produced in a central chiller plant and circulated through a network of pipes to the air handling units (AHUs) or fan coil units (FCUs) in different areas of a building. The chilled water absorbs heat from the indoor air as it passes through the cooling coils in the AHUs/FCUs, providing cooled air to the conditioned space.
If chilled water is not supplied to the cooling coils, several consequences can occur:
Lack of cooling: Without chilled water, the cooling coils cannot absorb heat effectively, leading to inadequate or no cooling of the air passing through the system. This means the AC will fail to provide the desired cooling comfort, resulting in an uncomfortable indoor environment.
Inefficient operation: AC systems that rely on chilled water are designed to work optimally with a specific cooling capacity and efficiency. If chilled water is not supplied, the system will struggle to meet the cooling demands, resulting in increased energy consumption and reduced overall efficiency.
Equipment damage: Operating the AC system without chilled water can cause significant strain on the components. The lack of proper cooling may cause the compressor, condenser, or other vital parts of the system to overheat, leading to premature wear and tear, increased risk of breakdowns, and potential damage to the equipment.
Reduced air quality: Inadequate cooling can affect the dehumidification process within the AC system. High humidity levels in the indoor environment can promote the growth of mold and mildew, leading to poor air quality, unpleasant odors, and potential health risks.
Increased costs: Inefficient operation, increased energy consumption, potential equipment damage, and the need for repairs can result in higher operating costs and maintenance expenses.
In summary, without chilled water, air conditioners that rely on chilled water systems will fail to provide the desired cooling performance, consume more energy, risk equipment damage, compromise air quality, and incur additional costs. It is crucial to ensure the proper functioning and supply of chilled water for these types of AC systems to maintain optimal performance and comfort.
