Water Cooled Chiller Vs Air Cooled Chiller Cop

However using state of the art technology with centrifugal compressors and variable speed control air cooled chillers are often the better.

Water cooled chiller vs air cooled chiller cop. 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. Packaged water cooled chillers are typically available from 10 to 4 000 tons 35 to 14 000 kw. Conventional thinking has been that water cooled chillers are more efficient 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.

Water efficiency is a key operational consideration where water cooled chillers are installed. The primary purpose of an air conditioner system is to manage the temperature of a room. This can usually go both ways as many air conditioners can cool down as well as heat. Factors such as water costs efficiency ratings and electricity can dramatically change the lifetime price of a chiller.

The metric calculation would be. 2 500kw 460kw 5 4 so the cop is 5 4. An option available for smaller systems is the use. Deciding which chiller type best suits your industrial process depends on several factors which include.

This means that for every 1kw of electricity you put into the machine you will produce 5 4kw of cooling. F air cooled reciprocating water chillers that have five years old installation operating at full load covering nominal cooling capacities from 17 kw to 525 kw. Packaged air cooled chillers are typically available in sizes ranging from 7 5 to 500 tons 25 to 1 580 kw. Water cooled chiller systems have a cooling tower thus they feature higher efficiency than air cooled chillers.

If we only look at compressor costs this may be true. Take for example a chiller which is producing 2 500kw of cooling or 8 533 364btu h in metric units. 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. Typically air cooled chillers are placed outside a building while you would keep a water cooled chiller inside.

One uses the air and one uses water. 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. Water cooled chiller cost comparison.
