1. What is a screw chiller?
Screw chillers have screw compressors, which can be water-cooled or air-cooled chillers.
The water-cooled chiller system usually puts the compressor on the top, while the air-cooled chiller puts them on the bottom.
2. What is a scroll chiller?
The working purpose of the scroll chiller is to humidify, dehumidify or cool the air.
Many scroll chillers work in the same way as air conditioners.
Vortex chillers can be water-cooled or air-cooled, and most of them are independent.
3. What type of water-cooled condenser is used for large water chillers?
Most water-cooled chillers use a circulating condenser to treat the refrigerant.
They may also have a cooling tower to facilitate this process.
4. What types of prime movers can be used for centrifugal chillers?
Centrifugal chillers use different types of prime movers, such as AC and DC motors.
They can also use variable frequency drive power supply, such as gas turbine or steam turbine and diesel or gas engine.
The main function of centrifugal compressor is speed regulation.
5. Why is it important to keep the operation log on the chiller?
It is important to keep the operation log of the chiller, because it will ensure the efficient and stable operation of the equipment.
Over time, cold water opportunities have problems.
If there is a log of system parameters, technicians will easily solve most problems.
Is the chiller also a condenser?
Chillers are different from condensers.
Water-cooled chillers operate with circulating condensers.
The condenser is only a part of the water chiller, which can work as expected.
6. Why is water-cooled chiller more efficient than air-cooled chiller?
The main reason why water-cooled chillers are more efficient than air-cooled chillers is the cooling tower.
This is because the cooling tower works according to the ambient bulb temperature.
7. What is the best chiller efficiency?
When the chiller operates at 70% to 75% load, it can achieve maximum cooling efficiency.
If it needs the lowest ECWT or the water temperature entering the condenser at this time, the chiller is being used in the best condition.
8. How to choose a chiller?
The first step is to determine the heat load requirements to select the appropriate chiller according to the needs.
Next, learn the type of coolant, flow rate and temperature setting required.
Other considerations include installation environment, performance curve and pump performance.
9. How to find the best chiller?
Once its main purpose is determined, the best chiller will be found.
Today, there are different kinds of machines used as water coolers for hydroponics.
Before purchasing the hydroponic water chiller, the required cooling capacity should also be determined.
