1.3 OPERATION OF THE ACF60-00
The ACF60-00 is a gas chiller with absorption cooling cycle and air condenser/absorber.
The liquid coolant is ammonia; the cooling cycle is run by thermal energy supplied by the
combustion of natural gas, and is therefore characterized as having a limited need for
electrical energy.
The ACF runs on either natural gas or LPG and requires an electrical power supply of 230
V 1N – 50 Hz.
The evacuating of combustion products is done using the exhaust cooling air exiting the
condenser by means of a fan.
Constructive Characteristics
The ACF chiller is available in 5 versions:
ACF60-00, for air conditioning/refrigeration applications in civil-commercial and industrial
environments. It has a nominal cooling capacity of 17.72 kW. Data Table: Table 2, page
11.
ACF60-00 TK, “Technological version”. Designed for air-conditioning/refrigeration in
process applications and systems; it is specifically designed to run without interruption 24
hours a day. It has a nominal cooling capacity of 17.72 kW. Data Table: Table 4, page 13.
ACF60-00 HT, “High Temperature air”. Designed to operate in locations that have high
ambient temperatures. It has a nominal cooling capacity of 17.12 kW. Data Table: Table
6, page 15.
ACF60-00 LB, “Low temperature”. Designed to provide refrigerated water down to -10°C.
It has a nominal cooling capacity of 13.30 kW. Data Table: Table 8, page 17.
ACF60-00 HR, “Heat Recovery”. This is an ACF60-00 with a heat recovery system able to
provide 17.72 kW of nominal cooling capacity when operating without the heat recovery
system. With the heat recovery system, it can obtain a cooling capacity of 17.93 kW, at
the same time providing 25.3 kW of heating capacity. Data Table: Table 11, page 20.
The indicated tables only provide some of the main technical data, for coefficients
and other information refer to paragraph 1.4 TECHNICAL SPECIFICATIONS, on
page 11.
All versions can be supplied with Robur grey or stainless steel panelling (for stainless
steel versions the symbol is “I”, ex. ACF60-00 TK I), with standard or silenced fan (for
silenced versions the symbol is “S”, ex. ACF60-00 TK S). The silent fan has a specially
designed nozzle, motor and impeller for less noise emission (See 1.4 TECHNICAL
SPECIFICATIONS, page 11), and is also available as a replacement.
For information on replacement parts contact Robur S.p.A. at +39 035 888 111.
Safety and Control Devices
The ACF is controlled by the electronic circuit board with an S61 microprocessor, located
in the electrical panel. This also functions as a monitor which displays messages and
