1.0 Technical Description

Generally

The BCOOL BAWC/H medium series, including air cooled water chillers and heat pumps, consists of 8 basic models covering ca-pacities from 39,4 up to 167 kW in cooling and 45 up to 194,2 kW in heating. It is the end result of a thorough study and accurate design by experienced BCOOL research and development teams, to develop a mid size chiller/heat pump series with compact shape, high performance and reliability of the highest quality standards. This series meets the highest levels of aesthetic and technical re-quirements, using the latest technological innovations, includ-ing environmentally friendly R407C or R410a refrigerant, that is chlorine-free and has zero ozone depletion potential. BAWC/H - M units are therefore ideal for installation in residential, commer-cial and industrial applications, due to their robust construction, high-efficiency performance, reliability, selected materials and low operating sound levels.

Casing

All units use metal parts that are fabricated from heavy gauge galvanized steel sheets, formed to ensure maximum rigidity that guarantees and preserves the unit's operation during the years. Af-ter fabrication these are degreased, phosphatised and electrostati-cally powder coated with an epoxy-polyester RAL 9002 coating of a thickness of 60-70 μm.This fully automatic process ensures superior corrosion resistance against the most aggressive ambient conditions. This treatment can successfully withstand a salt spray test of 500 hours, according to ASTM B-117.All components are assembled together using bolts, thus avoiding the need for welding which may harm the galvanization of the steel and ensuring that the whole assembly can fully withstand adverse weather conditions.The compact footprint of the unit arises from detailed study and design by our engineering teams and results in a machine which fits easily in restricted areas, is simple and easy to install and maintain and has been designed with special fittings for easy transportation and lifting.Removable side panels with special locks are used to permit access only to authorized personnel to internal components of the unit, for inspection and maintenance. Electrical and electronic equipment and components for proper unit's operation are located inside a weather proof (IP 55) electrical panel, with access via special key.

Compressors

All units use low-noise, maintenance free, Hermetic Scroll compres-sors with low vibration levels, especially optimized for use with R407C or R410a refrigerant, provided from world class suppliers. They are equipped with a crankcase electrical heater for the oil and are internally protected against potential overloading or electrical spikes.The compressors are mounted on special anti-vibration rubber mounts, to absorb and eliminate any vibrations from the unit's operation.

Air heat exchanger

All units' air heat exchangers are manufactured from high quality seamless inner grooved copper tubes according to ASTM B-280, having an outside diameter of 9,52 mm (3/8'').The fins are manufactured from aluminium and form the secondary extended heat transfer surface. The fins are con-tinuous across the heat exchanger and are fabricated in high precision dedicated press lines. The fin surface is waff le formed, so as to increase the fin rigidity and has special lou-vers that help to increase heat transfer. The combination of internally grooved copper-tubing and louvered fins has re-sulted in a heat transfer performance 30% superior to that of a conventional coil for this particular application. The assem-bly of the finned pack is achieved by mechanical expansion of the tubes in such a way, as to form a perfect mechanical bond with the fins. For this purpose, the fin holes have a peripheral extrusion (collar) of adjustable height. This extrusion serves to define the distance between the fins (and consequently the total heat transfer surface) and to ensure perfect contact of the fins to the tubes. Alternative fin materials are available upon request, such as epoxy - coated aluminium or copper for applications in especially aggressive environments.

Water heat exchanger

All units are equipped with a Shell and Tube, water–direct expansion type evaporator that has two separate cooling circuits, one for each independent refrigerant circuit. The casing is of steel and the internal tubes are of copper. There is an air vent valve, drain valve, differential water pressure switch, probes for water temperature sensors and the whole heat exchanger is wrapped in a heavy insulation material, ap-propriate for external installation.

Air heat exchanger fans

All units' fans are of the axial type, single phase, 6 poles, in-ternally protected against potential overheating, silent and suitable for outdoor installation. Due to the sophisticated aerodynamic design of the blades and inlet cones, as well as the perfect static and dynamic balancing, their operation is completely vibration-free. The fan-motor assembly has a protective grid against accidental contact with moving parts, which is designed according to ISO regulations. Fan motors are of the external rotor type, aerodynamically shaped so as not to interfere with the airflow and have permanently lubri-cated bearings that to do not require service. Continuous lin-ear fan speed regulation control is achieved according to coil temperatures, resulting in fan silent mode operation. This standard feature for BCOOL BAWC/H units saves energy and reduces sound levels dramatically, optimizing capacity.

4.4.1 Recommendations concerning the hydraulic circuit

To ensure proper operation of the unit, a minimum water volume is required in the system and the water flow must be within the operational range, as specified in the tables.

4.4.2 Water charge, flow and quality

All field connections must be carried out by a licensed technicianand must comply with the applicable local and national codes.Wat er he at exc h a n ger con ne c t ion s shou ld be m ade i n accordance with the unit outlook, respecting the water inlet/outlet.Install a flow switch or water differential pressostat (standardcomponent) in the water outlet piping, to prevent the unit fromoperating at a water flow which is too low. A terminal is providedin the switch box, for the electrical connection of the flow switch in the control circuit.To protect the water heat exchanger and avoid contamination and fragment, it is compulsory to install a filter in the water inlet pipe.It is essential to install a thermometer in the water inlet/outletpipe, to check temperatures.Provide heat insulation with suitable vapor barrier around thechilled water piping, to prevent condensation and capacity loss.Provide drain connections at all low points of the system, to allow complete drainage for maintenance and / or shutdown.

Air vents should be provided at all high points of the system, located where they are easily accessible for service. The water pipes are specially designed to obtain a complete air purge of the water heat exchanger.Provide flexible connection pipes at the inlet and outlet of the water heat exchanger, to prevent tubes vibration.Install an expansion tank on the suction side of the water pump, so that the water pressure on the pump suction shall be positive.

The frequent evacuation of the water system should be avoided.To avoid frequent on/off operation of the compressor, a minimumwater volume is required in the system (table 4.4.2). To assure proper operation of the unit, the water flow through the water heat exchanger must be within the specified limits (in table 4.4.2). The water quality should be in accordance with the specifications in table 4.4.2, to ensure the longest life span and optimum operation.

Be sure the water quality is in accordance with the specifications below.
