Diagnosing Car Air Conditioning Problems. To calculate system capacity the standard air.
Examine all AC and cooling system hoses for cuts abrasion weak spots and signs of leakage.
Car ac performance test. The first step you should take when checking your AC system is to run an AC performance test. This test will let you determine if your AC system is up to the task or not. Its a simple test.
All you need is a thermometer. They make special thermometers. Think your cars AC isnt cold enough.
Find out for sure with a quick test. If you need more information about how the system works or how to diagnose specifi. 7 Zeilen AC Cooling Test description.
This step determines if the AC system has at least the. Maintain test condition until AC system becomes stable. Approximately 10 minutes Check that test results of recirculating-to-discharge air temperature and ambient air temperature-to-operating pressure are within the specified value.
When test results are within the specified value inspection is complete. A typical AC system performance chart for a R134A system. Shows how ambient temperature and relative humidity effect pressure and outlet temperature.
You wont need any expensive Automotive AC Gauges for this test. The only tool you need is a cooking thermometer besides yourself of course. Just place the Thermometer in the center vent on the console set your ac to max cold and run the engine at 1500 rpm for about 5 minutes and you should see about a 20 - 30 degree drop in temperature form the outside temp.
To test in you will need an initial airflow measurement made with the Fieldpiece STA2 and the change in enthalpy across the coil using the Fieldpiece SDP2 One of the coolest tools I have seen this year. To calculate system capacity the standard air. The tests that should be performed in Air conditioner test room are cooling capacity test power consumption test.
The main objective of the manufacturers is to produce the systems according to requirements of customers which can give more cooling low power consumption high EER to with stand competition in the market. VBOX testing equipment is used by vehicle manufactures around the world to measure speed position and distance both indoors and outdoors. Typical applications include acceleration and deceleration testing lap timing measuring cornering g-forces vehicle performance benchmarking and.
Its that time of year and your looking to see if your AC is working as good as it should well here is the test for you. If you find that its not working as it should after these checks then you might want to take it to a professional to have it checked out and serviced. The vacuum side of the gauge must be calibrated to show 0 to 30 inches 0 to 762 mm Hg.
The pressure side of the gauge must be calibrated to register accurately from 0 pressure to a minimum of 60 psi 414 kPa. The maximum reading of the pressure should not exceed 160 psi 1103 kPa. This Video will show you how to perform a AC Performance Test.
I will also Describe some of the Tools you will need to check for an AC Leak. I will also Cove. During an air conditioning performance test the technician notices that the compressor outlet is hot.
Technician A says this is a normal condition. Technician B says the air conditioning system is. Restart the engine and turn on the air conditioning.
Observe the pressure readings. Though every air conditioning system will vary you want to see the high side pressure around 20 psi and the low side around 40 psi. If both the high and the low side are below these readings then you may need to add refrigerant.
Also check for belts that vibrate while the engine is running and the AC is on. This may indicate a belt that needs to be tightened or a defective automatic belt tensioner. Examine all AC and cooling system hoses for cuts abrasion weak spots and signs of leakage.
