Introduction
Ice Qube computer and electronics enclosure cooling systems have been designed to provide a safe environment for
your equipment. Our cooling systems provide this environment by cooling and dehumidifying the enclosure that
houses your equipment while providing an efficient, modern, and aesthetically pleasing package requiring minimal
maintenance. Our closed-loop circulation design also protects your equipment from air-borne dust and contaminants
which may hinder your equipment operations and cause unnecessary downtime. Ice Qube offers various models of
cooling systems ranging in cooling capacity from 1,000 to 27,000 BTU per hour to provide air conditioning systems
for many of your environmental needs, including hazardous locations. Ice Qube cooling systems are available in top
and side mount packages.
Basic Unit Operation
The Ice Qube Thermal Management System (TMS) is a combination of several systems that function simultaneously
to maintain environmentally friendly conditions for your equipment within the enclosure. The three main thermal
related systems that we employ are the closed-loop cold air supply stream, the heat rejection air stream, and the
vapor-compression refrigeration system.
The closed-loop cold air supply stream circulates cold air from the Ice Qube TMS to your electronics enclosure.
This air returns to the Ice Qube TMS bringing with it unwanted heat and humidity from inside your enclosure. Heat
and humidity is then removed by a heat exchanger which is part of the vapor-compression refrigeration system.
At the heart of the vapor-compression refrigeration system is a quiet, energy efficient rotary compressor, which
circulates environmentally friendly NON-CFC refrigerant to transfer heat from the heat exchanger (evaporator)
located within the closed-loop air stream to a heat exchanger (condenser) located in the heat rejection air system. In
the heat rejection air stream, air is circulated from the ambient air surrounding the enclosure, through a filter, and
across the warm heat exchanger. Here, heat from the enclosure is transferred from the warm heat exchanger to the
heat rejection air stream and dissipated to the ambient air.
