How do you measure evaporator temperature?
Measure the temperature of the suction line at the outlet of the evaporator coil. 75 degrees RA (design temperature difference of 35 degrees) 40 degrees evaporator coils. 40 degrees (heating of 8 degrees-10 degrees) 48 degrees-50 degrees suction line temperature. 2 degrees 46 degrees-52 degrees acceptable line temperature radius.
How do I check my AC temperature?
Step 1 Run AC for 15 minutes. Start the AC unit and let it work for about 15 minutes. Want to set a base line and get cooled things before running the test. Set a thermometer on the power register that is closest to the interior cooling equipment.
How do you size an evaporator?
If the evaporator is going to move 400 gallons per minute 14 x 400 5.600. Multiple response with 500 5.600 x 500 2.800.000. This response is the size of the evaporator, measured in BTU per hour. Divide the response with 12,000 2.800.000 12,000 233.33.
How do you measure condensing temperature?
In air-cooled capacitors, the difference in temperature between ambient temperature and condensation temperature is called capacitor division. For example, if the condensation temperature is 110°F and the ambient environment is 80°, the capacitor division would be 30°.
How do you calculate refrigerant?
Multiply this weight by 2.2 to convert it to 1.551 x 2.2 3.412 pounds. Divide this weight by the number of cycles the system will pass over time. If you cycle the refrigerant, for example, 20 x 3.412 20 about 170 pounds.
What is evaporator temperature difference?
The TD evaporator (temperature difference) is the difference between the saturation temperature by aspiration (evaporator boiling temperature) and the temperature of the box.
