3 Specifications
To supply and install, where specified in the project n° ………. unit(s) air cooled water chiller with cooling capacity of ………. kW, to cool ………. l/sec.
of water from ………. °C to ………. °C working with ………. °C ambient temperature.
The unit should work with electricity at ………. V, 3ph, 50Hz. The electrical power absorbed should not exceed ………. kW. The units COP will be at
least ………. at the working conditions of the project. Part load COP will be at least ………. at the working conditions of the project.
The units will have 2 or 3 independent refrigerant circuits, and the respective electronic microprocessor will allow the starting of the compressors. Each
chiller will be factory assembled on a robust baseframe made of zinc coated steel, protected by an epoxy paint.
The unit will be tested at full load in the factory at the nominal working conditions and water temperatures. Before shipment a full test will be held to avoid
any losses. Chiller will be delivered to the job site completely assembled and charged with refrigerant and oil.
Comply with the manufacturer instructions for rigging and handling equipment.
GENERAL
All units should be designed and manufactured in accordance with applicable selections of the following which are equivalent to American Air-
conditioning industry applicable codes:
REFRIGERANT
Will be accepted R-407C or equivalent refrigerant.
UNIT DESCRIPTION
Each chiller consist of multiple semi-hermetic rotary screw compressor, direct expansion avaporator, air-cooled condenser section, control system and
all components necessary for safe and controlled unit operation.
NOISE LEVEL AND VIBRATIONS
Sound pressure level at 1 meter distance in free field, semispheric conditions, shall not exceed ………dBA. The sound pressure levels must be rated
in accordance to ISO 3744. Other types of rating unacceptable. Vibration level should not exceed 2 mm/s.
DIMENSIONS
Unit length shall not exceed ………. mm, unit width shall not exceed ………. mm, unit height shall not exceed ………. mm.
CHILLER COMPONENTS
Compressors
9 The compressors shall be field serviceable, semi-hermetic, single-screw type with one main helical rotor meshing with two opposed gaterotor. Twin-
screw compressor will no accepted because of the large bearing loads inherent with this design. For a Single-screw compressor the two
exactly opposed gaterotors create two exactly opposed compression cycles which results in balanced forces acting on the rotor compressor. The
gaterotors will be constructed of a carbon impregnated engineered composite material. The gaterotor supports will be constructed of cast iron.
9 The oil injection shall be used for these compressors in order to get high COP also at high condensing pressure and low sound pressure levels in
each load condition.
9 Refrigerant system differential pressure shall provide oil flow throught service replaceble, 0.5 micron, full flow, cartridge type oil filter internal to
compressor. Filter bypass or oil pump not acceptable.
9 The compressor’s oil cooling must be realized by liquid injection. External dedicated heat exchanger and additional piping to carry the oil from the
compressor to heat exchanger and viceversa will be not accepted.
9 The compressor shall be provided with a high efficiency, oil separator and with built-in oil filter.
9 The compressor shall be direct electrical drive, without gear transmission between the screw and the electrical motor. The motor’s compressor shall
be designed for star/delta. Soft start should be available as option.
9 The compressor casing shall be provided with ports to realize economized refrigerant cycles.
9 Shall be present two thermal protection realized by a thermistor for high temperature protection to motor and a thermistor for discharge gas high
temperature protection.
9 The compressor shall be provided with an automatic spring return of capacity control valve to the minimum load position to ensure compressor
starting always at minimum motor load so with the minimum mechanical stress.
