1 Product Overview
The Vertiv
TM
VRC - VRC100, VRC101 or VRC102 is a compact, integrated, rack mounted cooling unit
(hereinafter referred to as “VRC1 Series”) is engineered for utilization in a 19” EIA server rack. The unit
should be used after reading the manual or consulting Vertiv. This chapter introduces the product
description, model description, product appearance, and main components of the cooling unit.
1.1 Product Introduction
The cooling unit is an integrated precision cooling unit that is a pre-engineered and pre-fabricated cooling
solution for server racks. It is specifically designed for the cooling demands of the equipment mounted
inside the rack, is precisely controlled and has a conducive and safe operating environment. The precision
air conditioner features high reliability, high sensible heat ratio and high airflow. The unit has the following
attributes:
• The cooling unit is installed at the bottom of the cabinet. The airflow path is depicted in Figure 1-1.
The hot return air enters the unit from the rear side of the cabinet and the conditioned cold air is
supplied from the front of the unit directly in front of the servers.

• The evaporator and heat rejection unit are placed in one enclosure. It’s easy to install being a
plug-and-play unit, eliminating the installation work such as electrical wiring, vacuuming and
refrigerant charge on-site and refrigerant piping.
• The cooling capacity varies from 25% to 100%, approximately 0.9 kW to 3.6 kW. It’s designed to
efficiently cater to part-load or variable cooling loads.
• The unit is designed by Vertiv for high efficiency and reliability, and includes the variable capacity
inverter compressor, electronic expansion valve, variable speed EC-fan, and controller.
• The evaporator EC fan provides energy savings by smoothly varying the fan speed to deliver the
airflow required to match the cooling load.
• The condenser fan speed ranges from 30% to 100% in sync with the variation in the compressor
cooling capacity.
