When the pipes are arranged in counterflow, a plate heat exchanger is highly efficient for transferring heat. A welded plate heat exchanger is a lower-cost alternative typically used in lower-flow applications, typically replaced rather than cleaned.
An air-cooled chiller uses mechanical refrigeration loops to dump heat from induction water into the ambient air. All the heat generated by the conduction process has to go through the cooling coils before being rejected back into the ambient air.
The cooler must be precisely sized. In addition, it is best to size the chiller to operate over long periods to allow good circulation in the cooling cycle and ensure that the chiller achieves stable operational temperatures.
Chillers require regular maintenance and replacement parts, which can both be costly.
As a result, good monitoring and treatment programs must be implemented to monitor the water quality and maintain good corrosion controls to protect the equipment and the pipe systems. In addition, water treatment and flushing (drain) is required to prevent corrosion, scale, and organisms from developing within the system.
Low-power systems typically need a compact air-to-water heat exchanger, whereas a higher-power system might need a larger air-to-water or cooling exchanger. Smaller conduction machines typically use plate-type heat exchangers with a water-to-water arrangement and point-of-service air-cooled chillers.
The closed-loop cooling system has moderate capital costs, low maintenance, and requires no makeup water or ongoing chemical treatments.
A smart controller on your cooling system can be used to set your water’s minimum and maximum temperature, complete with alarms.
