Water Cooled Chiller Vs Air Cooled Chiller Cop

If we only look at compressor costs this may be true.

Water cooled chiller vs air cooled chiller cop.

Packaged air cooled chillers are typically available in sizes ranging from 7 5 to 500 tons 25 to 1 580 kw. However water cooled chillers allow the refrigeration system to operate at lower head pressure making them more efficient and less costly to operate than air cooled chillers. Figure 2 show that air cooled cooling systems that ranged from 17 kw to 525 kw when operated at tropical outdoor temperatures and with presence of sandy storms will have. Deciding which chiller type best suits your industrial process depends on several factors which include.

Take for example a chiller which is producing 2 500kw of cooling or 8 533 364btu h in metric units. 2 500kw 460kw 5 4 so the cop is 5 4. The metric calculation would be. Water cooled chiller cost comparison.

In other words water cooled chillers can deliver higher cooling capacity with fewer units and a smaller footprint. Water cooled chiller systems have a cooling tower thus they feature higher efficiency than air cooled chillers. Water cooled chiller although both air cooled chillers and water cooled chillers function to remove unwanted heat from manufacturing processes they differ in various ways. This means that for every 1kw of electricity you put into the machine you will produce 5 4kw of cooling.

The primary purpose of an air conditioner system is to manage the temperature of a room. An option available for smaller systems is the use. The electrical power demand of the chiller to produce this is 460kw. Water cooled chillers are more efficient because they condense depending on the ambient temperature bulb temperature which is lower than the ambient dry bulb temperature the lower a chiller condenses the more efficient it is.

Water cooled chillers tend to have lower life cycle costs in warmer climatic regions in buildings where chillers are operated for long hours and where chiller capacity is typically larger than 1 5mw. Packaged water cooled chillers are typically available from 10 to 4 000 tons 35 to 14 000 kw. However using state of the art technology with centrifugal compressors and variable speed control air cooled chillers are often the better. One uses the air and one uses water.

Typically air cooled chillers are placed outside a building while you would keep a water cooled chiller inside. This can usually go both ways as many air conditioners can cool down as well as heat. Water efficiency is a key operational consideration where water cooled chillers are installed.
