Air Conditioning Test Rig Manufacturer,Supplier and Exporter in India
Product Code : EL-RACLE-9357
Jlab Export is a leading Air Conditioning Test Rig Manufacturer,and suppliers in India
This air conditioning test rig shows what happens to air as a vapour compression system cools it, dries it or adds moisture to it. It is a working laboratory model on a mild steel square tube frame with cast iron wheels and an instrumentation panel. Students use it for the cycle, the COP, the tonnage capacity and humidification and dehumidification tests.

Psychrometry Experiments on the AC Rig
Each test starts with the state of the air. Students read the dry bulb and wet bulb temperatures before and after the coil with a Psychrometer, then mark both states on the psychrometric chart. In the dehumidification run the coil is colder than the dew point of the entering air, so water drips off the coil and the humidity ratio falls. In the humidification run moisture is added, and the wet bulb temperature and humidity ratio rise.
The line between the two states splits the total heat into sensible and latent parts. For the tonnage figure, the air velocity at the outlet is taken with a Probe Type Anemometer Digital. Multiplied by the outlet area, it gives the air flow. Students then plot the refrigerant cycle on a p-h chart and compare the chart COP with the measured one.
Frequently Asked Questions
What is the difference between humidification and dehumidification?
Dehumidification removes water vapour: the air is cooled below its dew point and moisture condenses on the coil, so the humidity ratio falls. Humidification adds water vapour, so the humidity ratio and the wet bulb temperature both rise.
Which readings are needed to use the psychrometric chart?
Two independent properties fix each air state, and in the lab these are the dry bulb and wet bulb temperatures. From them the chart gives relative humidity, humidity ratio, dew point and enthalpy at that point.
What does conditioning the air mean?
It means controlling the temperature, the moisture content, the cleanliness and the movement of the air in a space at the same time. Cooling alone changes only part of that. On this rig students see two of these at work, as the air is cooled and its humidity is raised or lowered.
Why is the measured COP lower than the chart value?
The chart assumes an ideal cycle. In the rig, heat leaks into the cold parts, pressure drops in the lines and losses in the compressor and motor all take their share. The gap shows students where a real system loses performance.
What is the sensible heat factor?
It is the sensible heat removed from the air divided by the total heat removed. A low factor means the coil is doing much of its work drying the air, as happens in humid weather.
