Air-Cooled Chillers – Answering the What Question


Air-Cooled Chillers are basically a refrigeration system that work by transferring the heat energy from fluids.  Air-Cooled Chillers are used in a wide variety of settings and industries including medical, pharmaceutical, chemical, biotechnology, semiconductor, food, construction, plastic, and many others

Air-Cooled Chillers condense refrigerant.  This is accomplished by relying on a condenser, cooled by the ambient air, and fans to move the air over a finned coil to condense the refrigerant.  The heat removed by the air-cooled chillers is then transferred to the surrounding environment.  Often times this heat generates savings by heating or warming a space during the winter months.

Evaporation – In order to chill the fluid, a refrigeration process must first take place.   The refrigeration process and lowers the temperature.  A liquid refrigerant flows over the evaporator tube bundle where evaporation occurs, and vapor appears.

Compression – Once vapor appears, the compressor pulls the vapor from the evaporator and increases the pressure

Condensation –Leaving the compressor, the vapor reaches a condenser where the temperature is increased.  The refrigerant condenses in the condenser tubes and releases its internal heat to the air.

Expansion – The high-pressure liquid moves through the expansion valve and returns to the evaporator where the refrigerant pressure is reduced causing flash evaporation and auto-refrigeration of typically less than half of the liquid.

 

Advantages to Air-Cooled Chillers.

1 – There is less water consumption because a water source is not required.  Air-Cooled Chillers do not require a cooling tower.

2 – Easily set-up.  Air-Cooled Chillers are easy to set-up and start-up.

3 – Typically lower start-up costs.  No water treatment costs, lower maintenance costs.  Typically, Air-Cooled Chillers have fewer parts so there is less of a demand for maintenance.

4 – Less function space is required for Air-Cooled Chillers.  A mechanical room is not required, and the chiller may be placed in a parking lot or roof.

 

Budzar Industries has the capability and experience to design, engineer and manufacture both stationary and portable air-cooled chillers to your exact specifications.

Air-Cooled Chillers are typically located outdoors and can be on the roof, parking lot or at ground level, wherever there is access to a lot of fresh air to reject the heat generated by the process.  If the chiller is placed indoors, it is important that there be adequate ventilation.
