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
