Air Enthalpy Method Calorimeter

Air Enthalpy Method Calorimeter

Test Chamber

  • The chamber is made of Foam-core panel walls are superior to conventional walls in a number of ways.
  • Foam-core panels combine a high level of insulation with speed and ease of construction.
  • It resists high moisture levels do not significantly affect the R-value of foam-core panels.
  • The solid foam core virtually eliminates air convection within the walls and thermal bridges through wood studs and insulation voids.
  • The panels also reduce air infiltration that, with proper installation, make a tightly sealed chamber.  The Chamber MUST be installed indoor .

Data Acquisition System and Control Software

The data acquisition system is a solution for operating a test laboratory to measure the energy efficiency of Air Conditioners.
The modular system could upgrade the system easily with more input and output channels when the need arose. Data acquisition and control systems, installed in a control cabinet in the test laboratory, in the combination with the professional signal basic software .The thermocouple and the flow sensors will be connected directly to the devices without the need for any intermediate converters.

Data Acquisition System and Control Software Specification:
