Chiller HVAC

தயாரிப்பு விளக்கம்

In HVAC, a chiller isa refrigeration system that removes heat from a liquid, typically water, and then circulates the chilled liquid to absorb heat from a building or facility, providing cooling.

Here's a more detailed explanation:

• Function:

Chillers are the backbone of many large-scale air conditioning systems, particularly for commercial buildings and industrial processes.

• Mechanism:

They work by using a refrigeration cycle (like a refrigerator) to transfer heat from a liquid (usually water) to the ambient air or a cooling medium, such as water.

• Types:

• Air-cooled chillers:Use ambient air as the cooling medium to dissipate heat.

• Water-cooled chillers:Use a cooling tower to circulate water and remove heat.

• Components:

• Compressor:Compresses the refrigerant, increasing its temperature and pressure.

• Evaporator:Absorbs heat from the water as the refrigerant changes into a gas.

• Condenser:Cools the refrigerant back into a liquid state.

• Expansion valve:Reduces the pressure of the refrigerant before it returns to the evaporator.

• Applications:

• Cooling commercial buildings.

• Facilitating industrial processes.

• Cooling data centers.

• Maintaining temperatures for food storage and preservation.

• Advantages:

• மேலும் efficient cooling for large-scale applications.

• Can be used for both heating and cooling (heat recovery).

• Disadvantages:

• Can be more complex and expensive than traditional HVAC systems.

• Water-cooled chillers require cooling towers and water management systems.
