High demand for energy-efficient solution to be installed at corporate & retail offices
Solution : MULTI V IV
Air conditioning system with strong part load efficiency for saved electricity consumption
Energy savings of more than 30％ (vs. other brands), individual operation of each indoor unit
Office Building in Monterrey, Mexico
Background & Challenge
Corporativo Valmex, a tower of 11,000m2 with 24 levels, 14 of them intended for office area and 10 for parking. From its design, the objective was to offer a highly efficient building in energy consumption, both for owners and residents. After checking the technical comparison they made, U-Calli, the developer, opted to install 52 LG VRF units (MULTI V IV) with capacities of 12, 18 and 20 HP, which make a total of 560 tons of air conditioning installation.
Even after the structural reforms approved in 2014, the cost of electricity still remains uncompetitive in Mexico. Thus, it was important to have air conditioning system that allows high efficiency and considerable savings to the tenants because the use of air conditioning represents 50 percent of the total electric power consumption of a corporate office. Moreover, since the building was located at the Valle Oriente, the metropolitan area of Monterrey housing largest inventory of corporate offices and headquarters of multiple companies, the air conditioning system for the building had to provide highly reliable operation. Lastly, an individual control of air conditioning system for each floor in order to meet every consumer’s needs was critical for this high-rise building.
LG MULTI IV proved its strength in substantial energy savings that are incomparable to other brands.
In the search for a sustainable and environmentally friendly air conditioning system that complied with the regulations of Europe and the United States, a technical and qualitative comparison was made. With graphs of energy consumption in a given time, together with previous installation experiences, LG VRF system seemed to offer the substantial savings in comparison to its competitors.For this project, a total of 52 MULTI V IV outdoor units are installed on each floor. Unlike traditional chillers that had to run cooling operation for the entire floor even if only half of them were actually occupied, LG VRF allowed an individual control of air conditioning system for each place without all the equipment running. This helped consumers to use electricity more efficiently and allowed significant savings on expenses spent for energy use.
