6 FAQs about [Principle of water storage air conditioning]

What are the components of a chilled water air conditioning unit?

A chilled water air conditioning unit has a few major components, including the chiller, cooling tower, air handling units or fan coil units, pumps, and a pipe network. The chiller system cools water, which is then pumped through a network of pipes to air handling units.

How does an air handling unit provide cooling using chilled water?

Below is how an air handling unit provides cooling using chilled water: The chilled water from the chiller enters the cooling coil of the air handling unit (AHU) usually at about 6.7°C (44°F) and leave at about 12.2°C (55°F). The AHU blows air through the cooling coil and provides cooling to the room.

How does a water cooled air conditioner work?

The heat that is sent outside is cooled through a condenser coil. Once the heat evaporates, cool condenser water is then able to flow back to the chiller. This process repeats itself, keeping the building cool through a series of terminals or cooling coils. What Are the Benefits of Having a Water-Cooled Air Conditioner?

Do water cooled air conditioners consume water?

In short, water-cooled air conditioners do consume water due to the natural evaporation of water at the cooling tower. The chilled water is a closed-loop system. Hence, water will not disappear if there is no leakage. However, the condenser water is an open-loop system. When water is splashed across the fin of a cooling tower, it evaporates easily.

How does a chilled water storage system work?

Most chilled water storage systems installed today are based on designs that exploit the tendency of warm and cold water to stratify. That is, cold water can be added to or drawn from the bottom of the tank, while warm water is returned to or drawn from the top.

What temperature does a water cooled air conditioner cool?

These air conditioners cool water to somewhere in the 40 degrees Fahrenheit to 45 degrees Fahrenheit range (that’s 4.4 degrees Celsius to 7.2 degrees Celsius). On top of that, there are two types of water-cooled systems that you can choose from: the chilled water system and the cooling tower technology.
