Follow the narrative to see how small design choices affect everyday performance. In this video, we walk through a 3HP air enthalpy method calorimeter test laboratory, demonstrating how it accurately measures cooling/heating capacity, power consumption, and efficiency metrics like EER and COP for various air conditioner types. Watch as we simulate real-world indoor and outdoor conditions, from -10°C to 50°C, and explain the testing process for split, window, and inverter units according to ISO standards.
