1. Technical Description<br />
General<br />
The <strong>LPCA</strong>-HMB series air-cooled water heat pumps consists of<br />
12 models covering capacities from 188,2 up to 597,9 KW in<br />
cooling and 216,7 up to 677,5kW in heatng.<br />
It is the end result of a thorough study, and accurate design by<br />
experienced Interklima research and development teams, to<br />
develop a large size chiller series with compact shape, high<br />
performance, and reliability of the highest quality standards.<br />
This series meets the highest levels of aesthetic and technical<br />
requirements using the latest technological innovations, including<br />
environmentally friendly R407c that is chlorine free and has zero<br />
ozone depletion potential. <strong>LPCA</strong>-HMB units are therefore ideal for<br />
installation in urban environments due to their elegant design,<br />
selected materials and low operating sound levels.<br />
Casing<br />
All units use metal parts fabricated from heavy gauge galvanized<br />
steel sheets, formed to ensure maximum rigidity that guarantees and<br />
preserves the units operation during the years. After fabrication these<br />
are degreased, phosphatised, and electrostatically powder coated<br />
with an epoxy-polyester RAL 9002 coating of a thickness 60-70 Ì.<br />
This fully automatic process ensures superior corrosion resistance<br />
against the most aggressive ambient conditions. The treatment can<br />
successfully withstand a salt spray test of 500 hours, according to<br />
ASTM B-117. All components are assembled together using bolts<br />
thus avoiding the need for welding which may harm the galvanization<br />
of the steel, and ensures that the whole assembly can fully withstand<br />
adverse weather conditions<br />
The compact footprint of the unit arises from detailed study and<br />
design by our engineering teams and results in a machine, which<br />
fits easily in restricted areas and is simple and easy to install and<br />
maintain, and has been designed with special fittings for easy<br />
transport and lifting.<br />
Removable side panels are used to permit access only to<br />
authorized personnel to internal components of the unit for<br />
inspection and maintenance. Electrical and electronic equipment<br />
and components for proper unit operation are located in a weather<br />
proof (IP 55) electrical panel with access only via a special key.<br />
Compressor<br />
All units use low-noise, maintenance free, Hermetic Tandem Scroll<br />
compressors with low vibration levels, specially optimized for use<br />
with R407c refrigerant, selected from world class suppliers. They are<br />
equipped with a crankcase electrical heater for the oil, and are<br />
internally protected against potential overloading or electrical spikes.<br />
The compressors are mounted on special antivibration rubber<br />
mounts to eliminate vibration from the unit’s operation.<br />
Air heat exchanger coil<br />
All unit air heat exchangers are manufactured from high quality<br />
copper inner grooved seamless tubes according to ASTM B-280,<br />
having an outside diameter of 9,52 mm (3/8"). The fins are<br />
manufactured from aluminium and form the secondary extended<br />
heat transfer surface. The fins are continuous across the heat<br />
exchanger and are fabricated in high precision dedicated press<br />
lines. The fin surface is waffle formed, so as to increase the fin<br />
rigidity, and has special louvers that help increase heat transfer. The<br />
combination of internally grooved Copper-tubing and louvered fins<br />
has resulted in a heat transfer performance 30% superior to that of<br />
a conventional coil for this particular application. The assembly of<br />
the finned pack is achieved by mechanical expansion of the tubes in<br />
such a way as to form a perfect mechanical bond with the fins. For<br />
this purpose, the fin holes have a peripheral extrusion (collar) of<br />
adjustable height. This extrusion serves to define the distance<br />
between fins (and consequently the total heat transfer surface) and<br />
to ensure perfect contact of the fins to the tubes.<br />
Alternative fin materials are available upon request such as epoxy<br />
– coated aluminium or copper for applications in especially<br />
aggressive environments.<br />
Water heat exchanger<br />
All units are equipped with a Shell and Tube water –direct<br />
expansion type evaporator that has multiple cooling circuits, one<br />
for each independent refrigerant circuit. The casing is of steel and<br />
the internal tubes are of copper. There is an air vent valve, drain<br />
valve, probes for water temperature sensors differential pressure<br />
switch, and the whole heat exchanger is wrapped in a heavy<br />
insulation material appropriate for external installation.<br />
Air heat exchanger fans<br />
All unit fans are of the axial type, three phase, 6 poles, internally<br />
protected against potential overheating silent and suitable for<br />
outdoor installation. Due to the sophisticated aerodynamic design<br />
of the blades and inlet cones, as well as the perfect static and<br />
dynamic balancing, their operation is completely vibration-free.<br />
The fan–motor assembly has a protective grid against accidental<br />
contact with moving parts, which is designed according to ISO<br />
regulations. Fan motors are aerodynamically shaped so as not to<br />
interfere with the airflow, and have permanently lubricated<br />
bearings that do not require servicing. Continuous linear fan speed<br />
regulation control is achieved according to coil temperatures<br />
including fan silent mode operation. This optional feature for<br />
Interklima <strong>LPCA</strong> units saves energy and reduces sound levels<br />
dramatically, optimizing capacity.<br />

10.Installation<br />
10.1 Selection of location - service space<br />
The <strong>LPCA</strong>-HMB unit should be installed in a location that meets<br />
the following requirements:<br />
1. The foundation is strong enough to support the weight of the<br />
unit, and the floor is flat to prevent vibration and noise<br />
generation.<br />
2. The space around the unit is adequate for servicing and the<br />
minimum space air inlet and air outlet is available. If several<br />
units are being installed side by side in parallel, the minimum<br />
service space between them must be taken into account.<br />
3. There is no danger of fire due to leakage of inflammable gas.<br />
4. Ensure that water cannot cause any damage to the location in<br />
case it drips out of the unit.<br />
5. Make sure that the air inlet and outlet of the unit are not<br />
positioned towards the main wind direction.Frontal wind shall<br />
disturb the operation of the unit.If necessary, use a<br />
windscreen to block the wind.<br />
6. In heavy snowfall areas, select an installation site where snow<br />
shall not affect operation of the unit.<br />
7. Make sure that the unit can be fixed directly on concrete.<br />
8. In order to avoid the transmission of vibration from the<br />
operating unit to its carrying structure, the use of antivibration<br />
material to install under the supports of the unit is<br />
recommended. It is suggested to install a rubber pad between<br />
the points of support and the base of the unit, or spring<br />
antivibration mounts under each point of support of the unit.<br />

10.3 Recommendations concerning the hydraulic circuit<br />
ñ All field connections must be provided by a licensed technician<br />
and must comply with the applicable local and national codes.<br />
ñ Evaporator water connections should be made in accordance<br />
with the unit outlook respecting the water inlet – and outlets.<br />
ñ Water piping to be arranged so that the circulating pump<br />
discharges directly into the evaporator.<br />
ñ Install a flow switch or water differential pressostat (standard<br />
component) in the water outlet piping to prevent the unit from<br />
operating at a water flow, which is too low. A terminal is provided<br />
in the switch box for the electrical connection of the flow switch<br />
in the control circuit.<br />
ñ To avoid erosion, it is recommended to install a filter in the<br />
water inlet pipe.<br />
ñ It is essential to install a thermometer in the water inlet/ outlet<br />
pipe to check temperatures.<br />
ñ Provide heat insulation with suitable vapour barrier around the<br />
chilled water piping to prevent condensation and capacity loss.<br />
ñ Provide drain connections at all low points of the system to<br />
permit complete drainage for maintenance and/ or shutdown.<br />
ñ Air vents should be provided at all high points in the system<br />
located were they are easily accessible for servicing. The<br />
water inlet pipe is specially designed to obtain a complete air<br />
purge of the evaporator.<br />
ñ Install an expansion tank on the suction side of the water pump<br />
so that the water pressure on the pump suction will be positive.<br />
ñ To avoid frequent on/off operation of the compressor, a<br />
minimum water volume is required in the system (table 10.4).<br />
ñ To assure proper operation of the unit, the water flow through<br />
the evaporator must be within the specified limits in (table<br />
10.4).<br />
