What chiller that uses a screw type impeller is the?
centrifugal
What causes choking in water chiller evaporators?
Carbon dioxide
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.
What is Surge in centrifugal compressor?
Surge is a flow instability that results in a global collapse of flow through the compressor. Compressors do not continue to operate or flow once surge has occurred. Surge should be avoided. Surge is not the rough operation, vibration, pulsation, or noise that develops at low flow conditions. Surging is a momentary reversal of flow.When the pressure in the centrifugal comp. increases,the mass flow rate decreases.There is a limit up to which the pressure can be increased,then after the flow becomes instable and momentary reversal of flow take place,vibrations are produced and mechanical damage occurs.
What is centrifugal tension?
As with any other rotational system in a belt drive during rotation, the belt is subjected to centrifugal force. Due to the centrifugal force the belt is thrown outward from the grooves of the pulley and causes additional tensioning of the belt. The effect of centrifugal tension is that it reduces the pretension of the belt and hence increases belt slip.
How does an economizer function on a centrifugal chiller?
What is used economizer in centrifugal chiller
What type of chiller uses a screw type impeller?

How do you find centrifugal compressor is in surge?
Normaly, every centrifugal type comprssors provided with an antisurge valve or surge control valve. when compressor handelled with surge, the proveded surge control valve will become open automatically and the cycle will repeated till the comprssor is in surge.
Large amounts of loose rust in an absorption unit can cause?
In comparison to a 500 ton centrifugal chiller, a 500 ton absorption chiller requires
What does means surge on centrifugal compressor?
Surge is a point when compressor is not add enough energy to overcome system resistance.
Can reciprocating compressor surge?
Compressor surge only occur in centrifugal compressors. reciprocating compressor don't as they increase pressure by volume reduction, unlike centrifugal compressors where they increase pressure by converting kinetic energy to potential energy (pressure).
Which air conditioning is the most famous?
My opinion. Carrier centrifugal chiller. First put in service in the teens of the nineteenth century.
A sudden surge in lh concentration causes?

What causes high pressure in chiller system?
dirty coil
What causes choking in water chiller evaporators?
Carbon dioxide
