Unit construction

Compact, modular and weatherproof design air-cooled chiller for outdoor installation IP24 – manufactured according to the ISO 9001 quality standard. The range has been designed for both air conditioning and process cooling applications and meets PED conformity. The use of state-of-the-art technologies and high quality materials ensures efficiency, reliability and an extended service life. Each DAIKIN chiller is factory run tested prior to shipping.

Casing / Colour

Powder coated, galvanised steel plate. Fully factory assembled on a base frame. Colour ivory white (Munsell code 5Y7.5/1) or RAL equivalent silky grey (+-RAL7044) Number of refrigerant circuits

Size 110-170 single circuit.

Compressor

New, semi-hermetically sealed DAIKIN stepless single screw compressor developed and optimised for refrigerant R407c.

The single screw principle of a main screw meshing with 2 satellite rotors eliminates radial and axial bearing loads due to balanced pressures under all operating conditions. Bearings are designed for over 100,000 operating hours or equivalent to the full service life of the compressor.

The main screw is directly driven by a suction cooled 2 pole, 3 Phase induction motor and is cooled by refrigerant injection. Satellite rotors are made from a hard wearing polymer material eliminating metal to metal contact allowing closer tolerances and increasing running life. At 2880rpm and 12 compressions per rotation the 34,560 compressions per minute prevents pulsating compression gas and resembles a smooth discharge flow, thereby reducing vibration and noise emission. In addition the twin wall structure of the compressor casing together with the integrated oil separator offers additional attenuation.

Stepless control of the sliding vane determines the volumetric ratio of the compressor in function of the chilled water temperature. Control is infinitely variable from 30 to 100%.

Additional features include: integrated oil separator incorporating muffler effect, oil lubrication by pressure difference (no oil pump required), oil sump heating, oil inspection glass, non-return valve, hot gas shut-off valve, service valves, suction gas filter, Klixon embedded in the motor winding, star or delta start up.

The high efficiency design is optimised for the refrigerant and system and ensures the highest EER values and operational reliability. System and service costs are minimised.

Condenser

High-performance design Cu/Alu heat exchanger – arranged in a V- shape. Consisting of internally drawn helical Cu pipe (Hi -X) guaranteeing excellent heat transmission and optimal oil return. An integrated subcooler further improves performance. By increasing the heat transmission surface using continuous laminated honeycomb slotted flaps, a very low sound level is attained still with compact dimensions. The aluminium fins are precoated with Polyacryl to offer additional protection against corrosion thereby extending the range of applications of this device.

Fans

Directly driven, low-noise axial fans with outlet protective grating. Statically and dynamically balanced drive motor design with maintenance-free bearings for outdoor installation. Motor safety class IP 54.

Refrigerant Piping

Consisting of Cu pipe with all the necessary cooling fittings such as:

Service valves, filter-drier, inspection glass with moisture indicator, solenoid valve and TEV with external pressure equalisation. The refrigerant circuit is subject to factory pressure and leak testing, is cleaned, dried, evacuated and supplied with refrigerant R-407C and filled with oil ready for operation.

Safety and control devices

Permanent temperature and pressure monitoring of the refrigerant circuits by the PCO2 digital controller using high- and low-pressure sensors. Each refrigerant circuit is fitted with the following safeties: Pressure limitation control / safety pressure limitation control, drain valve, low-pressure switch, hot gas temperature monitoring, overheat cut-out for compressor and fan motors and overload relay.

Each refrigerant circuit is fitted with the following control devices: Electronic temperature monitoring, phase-sequence relay, high- and low-pressure PCO2

digital controller display, timing safety device and switch frequency limiter.

Switching and control device

In addition to the fully automated PCO2 digital controller, the control cabinet manufactured by SIEMENS in accordance with the valid EN directives (CE) fulfils safety class IP 54 and contains all the required switching and control components such as: load, auxiliary and control cut-outs, transformers, control fuses, relay and auxiliary relay, sensors, control PCBs and PCO2 digital controller.

The electronics have an automatic restart after power failure and provide the following digital inputs and outputs hard-wired to terminals for incorporating the GLT:

Digital inputs: Digital outputs:

*Remote On Off / dual set point / power limitation 1-2-3-4

PCO2 digital controller

The ERAP-MB units are fitted with a PCO2 digital controller, which allows the user to configure, operate and service the unit in a user-friendly manner. The controller consists of an alphanumerical display (LCD 4x20), 6 control keys and 6 LEDs.

The following functions are supported by the electronics, amongst other things:

- Allocation of the set point and the desired switching hysteresis

- Air temperature control using field installed sensor

- Adaptive control functions

- Various timer – date functions (Schedule –Timer)

-User display of current operating parameters such as temps, pressures, ect…

- Recording operating hours

- Automatic restart after power failure

- Service history of the last 20 alarms

- 5 languages can be freely selected (German, English, French, Italian, Spanish)

- Password protection

As an option this condenser can be fitted with an interface for integrating it into a Building Management System (BMS), which either supports the MODbus / J-bus or BACnet protocol.

4TW56119-2

Foundation is built on theground

Notes:

1 The measurement tabulated is based on the factthe base is made in the ground or on a concretefloor. In case the base is made on a rigidconcrete floor, it is possible to include thicknessof concrete floor in that of the base.

2 In case a base is made on concrete floor, be sureto provide a ditch as shown. It is important toextract drainage regardless of wether a base ismade in the ground or on the concrete floor(Ditch → Sewerage).

3 Ingredient ratio of the concrete is cement: 1,sand: 2, gravel: 3, which is standard and insertiron bars of J10 at every interval of 300 mm.The edge of the concrete base should beplaned.

Fix anchor bolts into the concrete foundation.The concrete foundation should be higher thanthe floor level by approximately 100 mm forease of plumbing work and better drain.Further, strength of the floor should be sufficientto support the weight of concrete foundationand unit.Be certain that the foundation surface is evenand flat.
