KTE-9000AU

Equipment Introduction

• This experimental device is designed to facilitate the operation, maintenance, repair, and experimentation of a vehicle cooling and heating system using an automotive HVAC module.

• Real-time monitoring is supported through a PC using a data acquisition system (DA100), and all experimental data can be stored and analyzed on the PC.

• This equipment is designed to help users understand the structure and function of each component in a vehicle cooling and heating system and to evaluate cooling and heating performance under various operating conditions
