Clean Energy Solutions: HVAC Systems
Philippines is one of the highest electricity rates in South East Asia. Each industrial facility finds ways to reduce its Energy, Operating & Maintenance Cost (E&OM).
ALPS MSI in partnership with Siemens Philippines, Inc. is committed to help industrial motor users in reducing its power consumption. Proper design that is suitable for its use and optimized for its consumption plays an essential role for the energy efficiency of motors and its drive systems. Modern drive technology offer an enormous saving potential of up to 70 percent. This is the case for new plants as well as for modernization’s (retrofits).
The key for this is in a targeted analysis of drive systems regarding their respective degree of utilization and energy consumption. The tailored selection or modernization of motors and converters based on this, often already pays off in a very short time through the energy cost savings achieved.
The decisive factor for the most efficient use of energy is in reducing the energy consumption to the real demand of the application. The path to this is via a comprehensive bundle of measures. For this purpose:
- costs and benefits of possible savings are compared with each other,
- the drive components are designed according to the requirements and
- the ideal path to sustainable realization of the entire concept are formulated.
ALPS MSI offers industrial facilities our technical and financing for reducing your energy consumption.
- Efficient use of energy through installation of modern energy-saving motors;
- Optimized use of energy through retrofit to variable-speed drives;
- Adjusting the energy expenditure to the specific requirement of the application;
- Improved motor start-up behavior;
- Low network load due to fewer harmonics;
- Reduced operational noise; and
- Less wear and tear through adjusted speed.
The type of heat rejection in a cooling tower is termed “evaporative” in that it allows a small portion of the water being cooled to evaporate into a moving air stream to provide significant cooling to the rest of that water stream. The heat from the water stream transferred to the air stream raises the air’s temperature and its relative humidity to 100%, and this air is discharged to the atmosphere.
Evaporative heat rejection devices such as cooling towers are commonly used to provide significantly lower water temperatures than achievable with “air cooled” or “dry” heat rejection devices, like the radiator in a car, thereby achieving more cost-effective and energy efficient operation of systems in need of cooling.
Think of the times you’ve seen something hot be rapidly cooled by putting water on it, which evaporates, cooling rapidly, such as an overheated car radiator. The cooling potential of a wet surface is much better than a dry one . ( Reference: http://www.cti.org/whatis/coolingtowerdetail.shtml )
This case study was completed in one of the largest coffee maker in the Philippines.
Energy Savings = (Baseline kW – After replacement, kW) / Baseline kW x 100%
= (12.12 – 6.665) / 12.12 x 100%
In October 17 results, power factor (PF) lower because it varies & depending load %.
Load, % = 6.650/11 x 100%
Based on Figure on the right side, the power factor (Red line) is closer to 0.665.

ALPS MSI offers upgrading your existing HVAC system or supply-install a new HVAC through a turnkey basis.
A properly designed fan blade will have a nonsymmetrical air-foil with a variable chord and twist to compensate for the peripheral change in speed from the blade tip to the wide chord.
Operating at 7680 hours, and electricity rate of ₱ 5.5/kWh, please find above financial results. This is an actual case study of Cooling Tower No. 7 from of the largest solar manufacturing company in the Philippines.
