This is car air conditioner simulation testing devices that is constructed based on the compartment of an actual car model.
The cooling capacity and heating capacity are determined at the car compartment side, and the measurement method is based on the air enthalpy method.
An electric motor outside the compartment is used in place of the car engine as the driving power source for the compressor, and the compressor torque is measured while controlling the peripheral temperature of the compressor and its speed of rotation. An air flow measuring device is installed in the condenser chamber for controlling the air flow based on the inlet air velocity.
The code tester (air flow measuring device) in the unit consists primarily of an air receiving chamber, a nozzle device, a rectifier, an auxiliary fan, differential pressure control and measuring device. With this device, the evaporator/condenser under test is installed directly in the air receiving chamber.
