Calorimeters to Test Energy Efficiency on Air Conditioners

Calorimetric test is important to certify the performance of a vehicle’s air conditioning system. This kind of machine is highly customised since the type of test depends on the kind of specimen and performance to be checked.

Test features:

• Energy evaluation: psychrometric method
• Temperature range: -20°C – +60°C (two or three cabinets)
• Temperature accuracy: ±0.2°C (in time)
• Humidity range: 20% – 90% R.H
• Main standards: ASHRAE, ISO, EN

Typical tests:

• Cooling system performance test (dual evaporators)
• Evaporator performance test
• Heater test
• Condenser test
• Radiator test
• Condenser and radiator connection test
• Expansion valve test
• Compressor test
• Blower test (P-Q curve)
• Linearity test for hot and cold wind gate
