The compressor's discharge temperature is often an overlooked temperature when troubleshooting a refrigeration or air conditioning system. However, it is very important because it's an indication of the amount of heat absorbed in the evaporator and suction line, and any heat of compression generated by the compression process.
The compressor’s discharge temperature can tell the service technician what is going on inside a refrigeration or air conditioning system. The discharge is a reflection of the hottest part of a refrigeration system, and there are limits as to ...
The main reasons of compressor discharge temperature overhigh are as following: (1) High return gas temperature. (2) Motor overheat. (3) High compression ratio. (4) High condensing pressure. (5
The compressor discharge temperature protection is triggered when the temperature sensor on the discharge tube of the compressor reads too high of a value. The cause of this can be a faulty sensor, a faulty board, or an actual fault in the refrigerant lines (i.e. blockage, kink, etc.). Verify code appears after resetting power to the system.
The discharge temperature is a measure of the superheated refrigerant's vapor temperature. Since the compressor's discharge temperature is a superheated vapor temperature measurement, a pressure/temperature relationship does not exist, and a pressure gauge cannot be used for its measurement.

The ideal operating temperature for an air compressor is between 50 and 85-degrees Fahrenheit. Within this range, mechanical components are not at risk of freezing or overheating due to ambient conditions. Most compressor manufacturers engineer their machine for a maximum of 105°F, which is the max rating of the motor insulation.
Reciprocating Compressor Discharge Temperature - posted in Industrial Professionals: Hello Friends/Vetarans,Well I was going through API 618 for Reciprocating Compressor. There I have found that it has been mentioned that the discharge temperature of recip compressor shall not exceed 150 C (300 F). So can anybody throw some light on this.
First off, if your discharge temperature (as measured with a thermometer at the compressor) is over 225°, you have an issue. At that temperature on the discharge line, you will have an internal compressor temperature of over 300°, and the oil will begin breaking down, so even if you check for no other reason, check to make sure you are under
im a milllwright a port townsend paper co in wasnington state were working on a older I R XLE compressor and we have the manual but theres is not a trouble shooting guide in it are problem is the compressor kicks out for HIGH DISCHARGE TEMP. ,we got 200-230 degree F air temp leaving comp at 110 PSI.
chilled water (compressor run time), reduce reheat energy and may increase the fan energy consumption. Figure 1 shows an example of an air handler that is running without a reset-schedule. The discharge-air temperature set point is set to a constant 52oF, and the actual discharge-air temperature never meets the set point.
I came across a problem when calculating the compressor discharge temperature. When using the GPSA databook to calculate a single stage centrifugal compressor discharge temperature, the result is much higher than that we gained using the simulation software ProII or a compressor sizing program. The formula in the GASP is: T2=T1 (P2/P1)^ [ ...
compressor discharge pressure saves approximately 1% of compressor energy consumption for each degree Fahrenheit reduction of condensing temperature. Adjust your minimum discharge pressure set points to 128 psig (75.8°F) and install a variable speed drive (VSD) on the condenser fans.
The airspray nozzle uses compressor discharge air to create a finely atomized fuel spray. By aerating the spray, the local fuel-rich concentrations produced by other types of spray nozzle are avoided, giving a reduction in both carbon deposition and exhaust smoke, The airspray fuel spray nozzle will typically have two or three air swirler circuits: an inner, an outer, and a dome.
try the formula as per below. T2/T1 = (P2/P1)^ (k-1/k) where k = 1.4. T1 = ambient temp. P2 = compressor discharge press. P1 = ambient press. P2/P1 = CPR = compressor pressure ratio. T1 = unit in kelvin by adding 273 if the unit in your plant is using 'C. Later on T2 just minus back 273K again to get the value in 'C.
temperature. The pressure ratio of the cycle is the pressure at point 2 (compressor discharge pressure) divided by the pressure at point 1 (compressor inlet pressure).

The SECU has detected an open S3, compressor air discharge temperature Switch. Machine could be overheated or there could be a faulty switch or wiring. Effect: Code 1 will cause a machine shutdown S3 Temperature Switch Circuit: Circuit Description: S3 is the high temperature shutdown switch for the airend discharge temperature. The switch
Compressor discharge temperature and pressure might have an impact on compressor reliability. For example, excessive discharge temperature might cause metal fatigue of the valves and thermal stress of the lubricant. Figure 2 shows the discharge temperatures for all the refrigerants during the tests of compressor 1 when it was run in the air-source air ...

Kaeser Air Compressor Overheating and Shutting Down. I have a Kaeser air compressor overheating shutting off , is there a specific volume of air that needs to inlet and exhaust. Its installed in a closed room. Response: There are a number of reasons why an air compressor will overheat.
If a booster is shutting down on high discharge temperature, one of the first things to check is the suction temperature of the gas. If it’s an air foam unit compressing air, the high temperature on the suction side of the booster is most likely coming from a faulty cooler on the compressor feeding the booster.
example, we'll cool the air. When the air just reach~s discharge line pressure, we'll stop the piston and cool the cylinder unitl the air tem perature reaches inlet air temperature. Again, Charles' Law enters the picture with a resulting drop in pressure to; 29.4 x 500 or 24.1 PSIA hlo
The higher temperature, the thin air inlet, it will cause the compressor lower efficiency and more times during loading, thus more heat during loading and high discharge temperature. 2. Normally compressors have the designed running temperature, when the ambient temperature is higher than the designed temperature, the compressor will stop for
Guys, We have a centrifugal 3 stage compressor air compressor for our plant.sicne few dayz back we started to experience high 3rd stage discharge temp.We got our after cooler bundles changed even though the problem presists.We checked all instrument calibrations.they are update and cross checked again first and second stage discharge ...
A reciprocating compressor has a cooling system built-in. This particularity, which cannot be implemented for centrifugal compressors, allows to have a discharge temperature close (but not equal) to the isentropic discharge temperature. 4. Multistage compression
A) change the switch to manual position on the switch board.B) check the lube oil sump level and conditions) open both the stage drain valve) open the compressor discharge discharge valve and feeling Valvo valve of air bottle.E) open cooling water system valves.F) Turn the compressor flywheel by hand ( 1 tURN)G) start the motor after draining
C7.8.6/0212-1215/E 3/4 6 Assembly of external discharge gas temperature protection For compressors with external discharge gas temperature protection (see Figure 1) the temperature sensor or the thermostat has to be installed with a distance along the - straight or bended - pipe of 120mm from the compressor
