Mechanical Installation;
Safety first…
The unit must be firmly secured to the soil. In addition, we are always following product installation instructions.
Noise
The unit is a source of noise mainly due to rotation of compressors and fans.
The noise level for each model size depends on the model of the device. If the unit is correctly installed, operated and manteined the noise emission level do not require any special protection device to operate continuosly close to the unit without any risk.
In case of installation with special noise requirements it could be necessary to install additional sound attenuation devices.
Minimum Space Requirements
It is fundamental to respect minimum distances on all units in order to ensure optimum ventilation to the condenser coils.
When deciding where to position the unit and to ensure a proper air flow, the following factors must be taken into consideration:
– Need to be avoid any warm air recirculation
-Need to be avoid insufficient air supply to the air-cooled condenser. Both these conditions can cause an increase of condensing pressure, which leads to a reduction in energy efficiency and refrigerating capacity
Sound Protection
When sound levels require special control, great care must be exercised to isolate the unit from its base by appropriately applying antivibration elements (supplied as an option). Flexible joints must be installed on the water connections, as well.
Water Piping
Water piping Piping must be designed with the lowest number of elbows and the lowest number of vertical changes of direction. In this way, system performance is improved.
The water system must have:
1. Anti-vibration mountings in order to reduce transmission of vibrations to the structures.
2. Isolating valves to isolate the unit from the water system during maintenance.
3. Flow switch, in order to protect the chiller must be protected against freezing by continuous monitoring of the water flow in the evaporator. In most cases, on-site the flow switch is set to produce an alarm only when the water pump switches OFF and the water flow fall to zero. it is recommended to adjust the flow switch in order to produce a “Water Loss Alarm” when the water flow reaches 50% of the nominal value, in this case the evaporator is protected against the freezing and the flow switch can detect the water filter clogging.
4. Manual or automatic air venting device at the system’s highest point.; drain device at the system’s lowest point.
5. Neither the evaporator nor the heat recovery device must be positioned at the system’s highest point.
6. A suitable device that can maintain the water system under pressure (expansion tank, etc.).
7. Water temperature and pressure indicators to assist the operator during service and maintenance.
8. A filter or device that can remove particles from the fluid. The use of a filter extends the life of the evaporator and pump and helps to keep the water system in a better condition. The water filter must be installed as close as possible to the chiller, as in Figs. 8 and 9. If the water filter is installed in another part of the water system, the Installer has to guarantee the cleaning of the water pipes between the water filter and the evaporator.
9. Before insulating water piping, check that there are no leaks.
Maintenance
Routine maintenance in Dubai
Chillers must be maintained by qualified technicians. Before beginning any work on the system the personnel shall assure that all security precautions should have been taken. Neglecting unit maintenance in these environments, could degrade all parts of the units (coils, compressors, frames, pipes, etc..) with negative effect on performances and functionality.
There are two different levels of maintenance, which can be chosen according to the type of application (critical/non critical) or to the installation environment. Examples of critical applications are process cooling, data centres, etc. Highly Aggressive Environments can be defined as the follows:
* Industrial environment (with possible concentration of fumes result of combustion and chemical process)
* Costal environment;
* Highly polluted urban environment;
* Rural environment close to of animal excrement and fertilizers, and high concentration of exhaust gas from diesel generators.
* Desert areas with risk of sandstorms in Dubai
