The scope of supply is a heat pump unit or heat pump plant containing several heat pump units to produce approximately 8 to
10 MWth of district heating. In later references to the heat pump unit, the same applies to a solution consisting of multiple
heat pumps.The cooling source for the heat pump is closed cooling water circuit. The scope of supply contains all the necessary
auxiliary equipment with piping and cabling (cabling from terminal boxes to control panels) of heat pump unit excluding the
main pipe work, civil works and power supply, but including commissioning and the test run completed (both approved by the
Purchaser) and ready for commercial operation at the Purchaser’s site. All materials, components and solutions used in the
proposed solution shall be proven functional and reliable.All necessary dimensions, load and process information for designing
the civil constructions and foundations is included to the scope of Supply.The heat pump is to be installed on a steel base
frames provided with motor, compressor and heat exchangers (evaporator, condenser, auxiliary cooling) etc. to form a complete
and well operating heat pump unit.The system shall be designed to minimize loss of refrigerant. Welded fittings are in preference
to flanged connections when possible. European standards such as EN 378 must be complied with. The refrigerants tendered shall
be safe and suitable for indoor installations: Safety classifications A1 and A2L are accepted. GWP < 500 is required to avoid
substances under HFC phase down.The process delivery of the plant with auxiliary systems shall include at least but not limited
to the following equipment, their installation, commissioning and testing:- heat pump unit with complete connections with
all necessary materials (bolts, nuts etc) and works of fixings, erections and installations (assembly of unit, painting and
thermal insulation)- refrigerant system with all needed auxiliary equipment and piping- lube oil system for required lubrication,
with all needed auxiliary equipment and piping- cooling water system, with all needed auxiliary equipment and piping- all
pipe work of the unit inside the delivery limits- complete protection system for heat pump unit- control, indication and measurement
equipment with instrumentation and supervision system with all necessary functions, auxiliaries and accessories- motor line
equipment including necessary cubicles and terminal boxes with all necessary auxiliaries and accessories- protective line
side surge arrester and capacitors with all necessary auxiliaries and accessories- all cabling inside the scope of supply
of the Supplier’s equipment- complete design of the process, design documents, instructions, operating and maintenance manuals
etc in the scope of supply are included in the delivery- spare parts according to Supplier’s recommendation for operation
of two (2) years (to be listed with unit prices with the tender by the Supplier)- all necessary special tools needed for installation,
erection, maintenance etc of equipment and systems shall be included in the delivery (separate list shall be submitted with
the tender by the Supplier)- factory tests and site tests of supplied equipment (separate list shall be submitted with the
tender by the Supplier)- commissioning and test run (to be approved by the Purchaser)- training of the Purchaser’s operating
and maintenance staff.
