How does a process chiller work?
How does a process chiller work?
Process chillers contain a chemical compound, called a refrigerant. An air-cooled condenser uses ambient air to cool and condense the hot refrigerant gas back down to a liquid. It can be located inside the chiller or can be remotely located outside, but ultimately it rejects the heat from the chiller to the air.
How do water chiller systems work?
A chiller works on the principle of vapor compression or vapor absorption. As the heat-transfer takes place, the refrigerant evaporates, changing from a low-pressure liquid into vapor, while the temperature of the process coolant reduces. The refrigerant then flows to a compressor, which performs multiple functions.
What is chiller RLA?
The maximum Amp drawn by the compressor motor is referred to as the RLA. The power to the motor of a 1272 kilowatt rated water cooled chiller will be cut if it reaches 455amps.
How is chiller flow rate measured?
Divide the cooling rate that you need, measured in British thermal units (BTUs) per hour by this answer. For example, if the chiller must absorb 3,840,000 BTUs each hour: 3,840,000 รท 13,000 = 295.4. This is the chiller’s minimum cooling rate, measured in gallons per minute.
What are LRA amps?
locked-rotor amperage (LRA) The very high current or amperage a motor draws when power is first applied, due to low counter emf. It is usually five to six times the running load amperage.
What are MCC amps?
Maximum Continuous Current (MCC) – Current measured just prior to protector trip. Locked Rotor Amps (LRA) – Current drawn by the compressor if the rotor is locked and can’t move while electric power is applied.
What are the different types of water-cooled chillers?
Modular to centrifugal. Carrier water-cooled chillers have tons of capacity. With a wide range of water-cooled chiller types (scroll, screw, and centrifugal), capacities (16 to 5,500 Tons) and sustainable refrigerant options, Carrier is a leader in the industry.
What is process water in a chiller?
The process water is the means by which heat transfers from the process to the chiller. Process chillers contain a chemical compound, called a refrigerant.
Do I need a reservoir and pumping system for my chiller?
It is very common to use water or a water/glycol solution to transfer the heat to and from the chiller which may require the process chiller to have a reservoir and pumping system. Regardless of your industry and process, making sure that you have sufficient cooling is critical to productivity and cost savings.
What is the capacity of a carrier water-cooled chiller?
Carrier water-cooled chillers have tons of capacity. With a wide range of water-cooled chiller types (scroll, screw, and centrifugal), capacities (16 to 5,500 Tons) and sustainable refrigerant options, Carrier is a leader in the industry.
