Part 1: System Composition Overview

The system is composed of the following components:

The function of the test chamber is to provide a stable environment with constant high and low temperature and humidity, as well as alternating high and low temperature and humidity; it includes a refrigeration system, heating system, humidification/dehumidification/waterway system, air duct system, control system, and system safety protection devices.
