SECTION 2 - PRODUCT DESCRIPTION
The principle of refrigeration is the exchange of heat. In absorption liquid chilling, there are
four basic heat exchange surfaces: the evaporator, the absorber, the generator, and the er.
See
Like any refrigeration system, absorption chilling uses evaporation and condensation to
remove heat. The absorption cycle uses water as the refrigerant and Lithium Bromide
(LiBr) as the absorbent. It is the strong affinity that these two substances have for one
another that makes the cycle work. The entire process occurs in an almost complete
vacuum.
CHILLER-HEATER COMPONENTS
The absorption chiller-heater consists of the following components:
• evaporator
• absorber
• condenser
• generator
• solution heat exchangers to heighten the cycle efficiency
• pumps to circulate the refrigerant and solution in the cycle
• purge unit to remove non-condensable gas from the machine
CONTROL PANEL
The absorption chiller-heater comes with a factory mounted and pre-wired control system.
The control panel enclosure is equipped with a hinged access door with lock and key. The
control panel includes a touch panel showing all system parameters in various languages
with numeric data in metric units. For details of the control panel, see
.
The unit is also equipped with two methods to start and stop operations:
• touch panel
• external signal
NOTE: Confirm the main power switch is within 6.56 feet (2 meters) of the ground. If not,
please install the operation platform.
WARNING: Turn off the power supply by the handle breaker when opening the control
panel.
