INTRODUCTION:
Ice Qube’s Thermal Management
S
ystem, TMS, is designed to cool, dehumidify or heat the internal
environment of modern electrical enclosures. Ice Qube offers efficient and aesthetically appealing
packages that can be mounted on top or on the side of your enclosure. Our closed-loop circulation
design protects your equipment from air-borne dust and contaminants which may hinder equipment
operations, causing unnecessary down time. Ice Qube is able to provide cooling capacities from
1,000 to 27,000 BTU per hour - a wide range of cooling systems to satisfy many of your conditioning
needs.
BASIC OPERATION:
The Ice Qube’s Thermal Management System, TMS, is actually a combination of three independent
systems which function simultaneously to maintain environmentally friendly conditions for various
types of electronic equipment enclosures. These three thermal related systems are: the closed-loop
cool air system; the warm air system; and the vapor-compression refrigeration system. Please refer
to Figure 1.
The closed-loop cool air system circulates cold air from the Ice Qube TMS to the electronics
enclosure. This air returns to the Ice Qube system bringing with it unwanted heat and humidity from
inside the enclosure. Heat and humidity is then removed by a heat exchanger located within the Ice
Qube TMS. This heat exchanger is part of the vapor-compression refrigeration system.
At the heart of the vapor-compression refrigeration’s system is a quiet, energy efficient rotary
compressor which circulates environmentally friendly NON-CFC refrigerant. The main purpose of this
compressor is to transfer heat laden refrigerant from the evaporator, located within the closed-loop
cool air system, to a condenser, located in the warm air system. In the warm air system, air is
circulated from the ambient surrounding the enclosure, through a filter, and across the warm air
system heat exchanger. Here, heat from the enclosure is transferred from the warm air heat
exchanger into the warm air stream and dissipated to the ambient.
