Chapter 1: Description & Specifications
1.1 Foreword
Note:
All operation of this unit shall be performed by qualified persons such as engineers
and technicians.
This manual shall only be used as the guide for the installation and operation of the ICE HC
Series Combination Air Conditioner and Heat Exchanger Cabinet Climate Control Units.
It introduces the installation, operation and regular maintenance of the unit.
1.2 General Description
The HC series Air Conditioner with Heat Exchanger (Combo Unit) is a cooling solution
developed for cabinets. It is designed for applications where internal equipment of the
cabinet emits a large quantity of heat and needs to be isolated from the outdoor environment
completely. The unit integrates a heat pipe exchanger with air conditioner. When the external
ambient temperature is lower than the cabinet inner temperature, the heat pipe exchanger
reduces heat-dissipating consumption.
The operating principle of Air Conditioner with Heat Exchanger is shown as Figure 1. The
heat exchange system and air conditioner share the same indoor/outdoor fans.
The heat exchanger and the compressor of the Air Conditioner with Heat Exchanger
adopt grading interlocking control. The heat exchanger is defined as the first level heat
dissipation and the compressor is defined as the second level cooling. According to the
cabinet internal/external temperatures, dividing into four operating modes: internal fan
running, heat exchanger running, air conditioner running and both running.

IMPORTANT
The air conditioner must be kept vertically strictly in accordance with the
instructions on the package during transportation, storage and use.
