What is low pressure and high pressure in water chiller unit?
In regards to a water chiller unit, the terms low pressure and high pressure refer to the compressor, which takes low pressure and compresses it into high pressure gas, which is then turned into a liquid to cool the unit.
Why water filter is provided at water inlet of water cooler?
So that the internals of the cooler don't get gunked up by precipitates that come out of suspension when the water is chilled. Solubles will still precipitate out.
What is the purpose of an intercooler in an air compressor?
Intercoolers lower the temperature of air going from one stage of a compressor to another, it increases the efficiency as the air becomes more dense. As the recieving stage is compressing cooler air as result, there is less heat produced in the succeding stage. If the intercooler has a large surface area, the temperature can approach ambient temperatures, and moisture my drop out, requiring a method for it's removal; if not a slug of water could damage the recieving stage. Efficiency increases can be had >15%
What are the possible faults that can occur to an air compressor?
Maybe if it's not working the breaker has flipped. This can be due to a whole new range of electrical issues. Also, it may be not working because it shut off due to being full of condensation water. Some will shut off when they sense they are full, some will fill until the compressor mechanically cant produce compressed air (as water (theoretically)cannot be compressed ), and some will fill until the flood the motor.Maybe the sidewall of the compressor has rusted through creating a hole, or maybe its missing a fitting. In either case the compressor can't create a store of compressed air causing it to run constantly. Since these compressor are mostly designed for intermittent use only, it will eventually wear or burn itself out.If the compressor itself has failed it will be due to issues in one of two categories; mechanical and electrical. If this is a refrigeration compressor, then the issue is most likely mechanical. If this is a smaller, more common sized reciprocating compressor such as one's often used to inflate car tires, then most likely the issue is electrical. It could still be a mechanical issue due to internals wearing out.Possible electrical problems with this type of compressor:-Loose electrical connections:-if connections are loose the voltage drops. when the voltage drops the motor draws more current through the wire the maintain motor speed causing overheating. the most cost effective fix is total replacement.-Breaker overloaded:- if the breaker which the compressor draws power from is overloaded, when everything is running, the compresser cant get enough power. just like above, the motor will work too hard and overheat.Other electrical issues provided through Google search:Stator burn: Improper or unbalanced voltage and poor motor cooling.Single Phase Burn: Loss of one phase on a three phase system.Half Part Wind Burn: Loss of supply to one winding set on a two winding motor(Part wound).Loose Connections: Loose electrical joins causing a voltage drop.Starting Components: Damaged starting capacitors and relays.Inpure Power Supply: Spikes or surges of current flow.Shorted Power Terminals: Over torquing power terminals.Mechanical issues with reciprocating compressor for refrigeration :Flood Back: Liquid refrigerant returning to the compressor during the running cycle.Flooded Start: Crank case oil diluted with liquid refrigerant due to off cycle vapour migration.Liquid Slugging: Liquid refrigerant or excess amounts of oil entering the cylinders during the running cycle.Excessive Discharge Temperatures: Higher than design superheated discharge gas temperatures.Compressor Oil Loss: Quantity of oil returning from the system is less than that leaving the compressor.Perform a Google search for other possible information or contact a professional such as a small motor technician, plumber, HVACR guy, electrician, or handyman.
What is the possible cause of pump cavitations?
Two of the most common causes of pump cavitation are air in the pump or the fluid being pumped is too hot. Water at 180 degrees will cause the pump to cavitate (steam bubbles form in the eye of the pump on the suction side of the impeller) because of the drop in pressure created on the suction of the pump. This can be corrected by either pumping cooler water, or by raising the net suction head of the pump. Air in the pump can be corrected by venting the pump.
Procedure to switch on chiller plant?
If your chiller has the option of controlling the pumps then the start command should go to the chiller. The start command could be from a time clock or BAS. The chiller then starts condenser and cooler pumps then starts the compressor. It is important to allow the chiller to control the pumps to protect the tubes from freezing. The old way was often to turn on the chilled water pump then the chilled water flow switch would start the chiller. Check the installation, operation and or maintenance books for your specific machine, if you don't have them get them! many can be downloaded. Go with the manufactures recommended procedures to CYA!!
What is an aquarium chiller used for?
You would use a aquarium chiller to cool the water in your aquarium for certain types of fish that need cooler water then room temperature. It helps to keep the water at a constant temperature.
Where could I rent or buy water cooled chiller equipment in LA?
you can rent or buy water cooler . you can check on the www.1stcooling.com or polandspring.com
How does an air cooled chiller work?
The air cooling of a chiller signifies , the cooling of radiator. in a chiller the compressor compressors the gas which on expansion cools in side Copper tubes causing the chilling effect. The refrigerants get heated up when compressed in a compressor. this heated refrigerant is cooled by blowing air in air cooled chillers. There are also water cooled chillers.
What does a water chiller do?
what does a water chiller do ? will heat or cool water
What is low pressure and high pressure in water chiller unit?
In regards to a water chiller unit, the terms low pressure and high pressure refer to the compressor, which takes low pressure and compresses it into high pressure gas, which is then turned into a liquid to cool the unit.
How do I fix my Sunbeam Water Cooler?
Sometimes people mistakenly refer to a water dispenser as a water cooler. The dispenser simply dispenses water with no change to temperature. The water cooler will cool the water as well. If you have one that is supposed to cool the water but isn't then there is likely a problem with the compressor.
What are the advantages of water-cooled chiller over air-cooled chiller?

How much power does an 800kW chiller use?
It depends on if you are running it fully all the time. Many things affect the energy consumption of a chiller...The condenser water temperature, the current load in the building..etc. The compressor is what uses the most energy, so if you can minimize the work the compressor has to do by decreasing the condenser water temperature (doing this forces you to use more energy on the cooling tower fan) then your chiller will use less energy. Building automated controls weigh the pros and the cons and do constant optimization to decided which uses more energy in this handoff
Do you prefer a centrifugal compressor over a screw compressor?
Screw chiller running with a male & female blade,Centrifugual chiller running with an impeller. Screw chiller are very reliable on more load like more than 200 tr ,its less consumption comapare to other chillers.
Can you use the air coold chiller instead of water coold chiller?
No you female dog!
How water chiller works?
Water cooled chiller work on principal that water is circulated in condenser for removal of heat from the system and refrigerant gas is thus condensed in condensor.
