Answer / azhar iqbal

cooling chamber is used in the turbine to control it's
exhaust temperature and in this way to increase it's
efficiency by 2-3% almost.
Also it is used to protect the damaging of the turbine
blades as high temperature currents flow upon them after
combustion.

Answer / eng.walid rezk

the compressor cannot work with the exhaust air
because if we do that the area under the curve of p-v
diagram will increase it is input work on an open system so
it equal -pdv as you must know so the area increases this
mean as well the work required increases and the over all
efficiency will decrease as well so in the two stage
compression cycle we had to make a water inter cooler to
reduce the work consumption

Hai, iam renjith. my qtn about the calorex heat and cool pump. What is the reason of the above machine is trip on high pressure. r134a gas using in this system. 8 months old. model is calorex propac 90(3 phase). This system has 2 compressor. Both are starting on 13amps after that rise up to around 21 within 1 minute. After will be trip on high pressure. Showing 68 psi in suction side on standby mode. Can i have a solution without delay?
