Plate-and-frame heat exchanger. In this type of water economizer, the water from the cooling tower is kept separate from the chilled-water loop by a plate-and-frame heat exchanger. This is a popular configuration because it can achieve high heat-transfer efficiency without cross-contamination. With the addition of a second condenser-water pump and
Free Cooling in Modular HVAC Chillers
The energy ratio between a chiller and free cooling is 5 to 1 compared to mechanical cooling. Gain the full benefits of free cooling. Alfa Laval is the only supplier offering the combination of adiabatic cooler or dry cooler and gasketed plate heat exchanger at the core of air-based free cooling systems. Efficient heat exchange is the key to
HVAC Water SystemsPrinciples Chilled water systems use chillers that typically operate at 0.5 to 0.7 kW/ton in a partial load regime while free cooling systems typically operate at 0.05 to 0.15 kW/ton. 2 A flat plate heat exchanger is used to isolate the chilled water loop from the open tower condenser water.
Heat Exchangers. Structure a system that combines a cooling tower with a plate heat exchanger, and you'll save money from day one. You'll also get a system that maintains effective fluid isolation and cools HVAC or process liquids more efficiently. A tower system with a heat exchanger is far less expensive to buy than any evaporative cooler.
ParaFlow Plate Heat ExchangersUsing the free cooling available in the outside air under optimum wet bulb conditions, this system delivers cooling tower water with a temperature that minimizes chiller operation. The key is the highly efficient Paraflow plate heat exchanger, which provides heat transfer and simultaneously isolates and protects expensive air conditioning equipment
POLARIS Plate Heat Exchangers employ the free cooling (or waterside economizer) concept to reduce hours of mechanical chiller operation. Taking advantage of ambient temperatures, tower flow can be diverted to the POLARIS PHE with the chiller turned off, achieving significant electric usage savings. IN TYPICAL FREE COOLING
Plate Heat Exchanger and Free Cooling Quality #1Plate Heat Exchanger and Free Cooling - This plate heat exchanger is used in a data center for a chilled water system and is a chilled water economizer. Heat exchangers are used in marine applications, industrial processes including chemical processing systems, food processing, and many HVAC applications including chilled water applications, hot water
