Dynamic Lift Control. An alternative method is what Thermal Care calls “Dynamic Lift” control technology. This method is used to adjust the pressure in the condenser based on the temperature of the outside air, the process heat load, and the peak efficiencies and performance points of the components in the chiller.

How Do Chillers And Cooling Towers Work?

How Do Chillers And Cooling Towers Work?

Jan 04, 2022 Cooling towers operate as large-scale heat exchangers, often placed atop a building, blowing air across a coil to remove heat. A chiller, meanwhile, is a large piece of industrial equipment located inside a building. There are many different types of chillers, yet all chiller models will contain an evaporator and a condenser. How Do Cooling […]

Energy Savings through chillers - Chiller Cooling Best Practices

Lift is defined as the difference between the evaporator pressure and condenser pressure. The thermodynamics of lift has a profound impact on a chiller’s energy consumption (Figure 1). Chiller load is the amount of cooling the chiller provides, while lift determines how hard the chiller must work to deliver the cooling.

More About Chillers for Low-Lift Conditions Process Cooling

Mar 01, 2010 Low-lift conditions also impact a chiller’s oil-management system. For example, hermetic chillers under low-lift conditions could lose oil at an increasingly faster rate through the motor bearings and refrigerant-gas seals. When this happens, large amounts of oil will enter the refrigerant circuit and migrate to the evaporator.

Increase Chiller Efficiency by Reducing Lift Buildings

Oct 25, 2018 The condenser uses an expansion valve to regulate how much of the cold refrigerant is released into the evaporator to meet your cooling needs. Lift is determined by subtracting the temperature of the chilled water going out to your building (typically 42-46 degrees F.) from the temperature of the water that’s leaving the condenser to be cooled by a …

How Cooling Towers Work? (HVAC Applications)

Water and Airflow Direction inside a Cooling Tower. Once the water passes through the cooling tower infill, heat is rejected via evaporation and the water is then collected on a basin at the bottom of the cooling tower before flowing back to the pipeline. In HVAC, the water leaving the cooling tower is known as the condenser water return (CWR).
