1 Overview
This chapter introduces the product description, model description, product appearance and main components of
Vertiv™Liebert® XDH High Heat Density Precision Air Conditioner (hereafter referred as Liebert XDH). The Liebert XDH
is a specially engineered equipment for the applications which does not permit any unauthorized and unqualified access
in the system. It must be used only by professionally trained personnel if it is placed in shopping malls, light industry, or any
business environment.
1.1. Product Introduction
The Liebert XDH unit is suitable for the environmental control of small and medium-sized modified computer rooms,
modular computer rooms, and large computer rooms that require energy saving and high heat density. It is designed to
ensure precision equipment such as sensitive, industrial processing, communication, and computers have a controlled
operating environment.
It also has features such as high reliability, high sensible heat ratio, and large air volume; it uses R410A an energy-
eicient refrigerant to meet the international environmentally safe requirements. The finned tube heat exchanger with a
sophisticated design and layout provides excellent heat exchanging performance. The EC fan with large air volume and
low energy consumption makes the system run more energy-eicient. The electronic expansion valve (EEV) intelligently
controls the uniform distribution of refrigerant flow and eectively solving the heat dissipation problem of the high heat
