Well, the general consensus is somewhere between 14 to 20 degrees colder than the intake temperature. From my example, 55 to 61 degrees would be an acceptable range.
If there are zones calling for heating and the economizer is working properly, then the set point can be increased. Are set points too high or too low; discharge-air temperature too warm or too cold? Typically, the discharge-air set point should never be lower than 55oF or higher than 70oF.
Therefore 275F discharge line temperatures represent an extreme temperature condition, 250F is usually considered a danger level, and 225F and below is desirable for reasonable life expectancy.
At that temperature on the discharge line, you will have an internal compressor temperature of over 300°F, and the oil will begin breaking down, so even if you check for no other reason, check to make sure you are under 225°F.
This discharge temperature should never exceed 225°F. Carbonization and oil breakdown can occur if compressor discharge temperatures exceed 225°. The three causes for high discharge temperatures are: High condensing temperature.
If the compressor's discharge line temperature ever gets higher than 225°F, the system may start to fail from worn rings, acid formations, and oil breakdown.
High Discharge Temperature
If the temperature exceeds 200 degrees F, oil life can be reduced. Air compressors commonly have an automatic shutdown feature that activates at 220 to 230 degrees F. The compressed air discharge temperature out of the compressor package should be below 100 degrees F.
It is desirable to limit discharge temperatures to below 250°F to 275°F (121°C to 135°C) to assure adequate packing life and to avoid lube oil degradation. At temperatures above 300°F (149°C), eventual lube oil degradation is likely, and if oxygen is present, ignition is possible.
Well, the general consensus is somewhere between 14 to 20 degrees colder than the intake temperature. From my example, 55 to 61 degrees would be an acceptable range.
Normal operation temperature range in the discharge line is between 185℉ and 190℉. If the temperature exceeds that range, then there could be issues. Shutdowns occur in most machines at around 220℉, and many have an automatic shutdown feature built in at 220℉ to 230℉.
L6 – Discharge Air Heat Warning
The code “L6” indicates that the air flowing out of the unit (known as discharge or “head”) is too hot for normal operation. Typically this can be fixed by cleaning the air filter.
If the Compression ratio is too high, it increases the discharge temperatures. By raising the unit's suction pressure and decreasing the discharge pressure, lowering the compression ratio in your air conditioner can dramatically reduce the discharge temperature.
Heat pumps usually produce air that is 85-92°F. This is plenty warm to heat your home to your desired 72°F. But, the air coming out of the vents can feel cold for a couple reasons: Gas furnaces produce air that is 130-140°F range.
In general, the ideal room temperature and your home for both efficiency and comfort fall somewhere between 68° and 76°F.
The average discharge temperatures from load bank can range from 300 to 400 degrees Farenheit over ambient. The discharge temperature varies by model and the amount of kW.
The standard temperature in aviation is measured at the mean sea level (msl) pressure of 29.92 inches of mercury (inHg) and is 15 degrees Celsius (C) or 59 degrees Fahrenheit (F). The standard temperature decreases 2 C or 3.5 F for every 1,000 feet gained, and this is reasonably accurate up to 36,000 feet msl.
While the standard room temperature of 72 degrees Fahrenheit is commonly favored by many, others argue for higher settings, particularly when it's hotter outside.
Keeping a close eye on this temperature helps ensure optimal performance and prevent potential issues in your HVAC/R system. The maximum allowable discharge temperature for any compressor is 225 degrees F. Exceeding this limit can lead to system failures caused by worn rings, acid formation, and oil breakdown.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Ideally, there should be a temperature differential of around 14° to 20° Fahrenheit between the incoming air and the air being blown out by your air conditioner. This means that if the air entering the system is 75°F, the air coming out of the vent should be between 55°F and 61°F.
The maximum allowable temperature for pumps refers to the highest temperature at which a pump can operate safely and efficiently without suffering damage or impairment to its function.
The limit to any compressor discharge temperature is 225°F. If the discharge temperature gets higher than 225°, the system may start to fail from worn rings, acid formations, and oil breakdown. Remember, if the discharge temperature is 225°, the actual discharge valve will be about 75° hotter.
That will depend. If the AC system is operating correctly, then the air coming out of your vent should be about twenty degrees cooler than the regular temperature inside. So, if you're cooling it and the house is 80 degrees, then you would ideally want the air to be about 60 degrees.
WHAT TEMPERATURE SHOULD THE AC BLOW? As a rule of thumb, when the ambient air temperatures 70° degrees Fahrenheit (21° Celsius) and humidity 20%, the AC outlet air temperature should be in the 35°-40° degrees Fahrenheit range.
