Welcome Back, Cooling Season!

Now that the weather is getting warmer, building occupants are requesting cooler spaces to keep them comfortable. This request has facility managers and building owners searching for flexible and energy-efficient HVAC systems that can minimize operating costs while still offering personalized comfort to occupants throughout the summer months. CITY MULTI® Variable Refrigerant Flow (VRF) from Mitsubishi Electric Cooling & Heating (Mitsubishi Electric), specifically the most recent generation of products – the L-Generation (L-Gen) – offers energy-efficient technology that provides superior cooling capabilities for commercial applications.

If you’re looking for a cooling solution for your next project, here’s a deeper explanation as to why we here at the Advanced Products Group (APG), a division of Aireco Supply, Inc., have chosen to use L-Gen.

Variable Evaporating Temperature Control

Variable Evaporating Temperature Control (VET Technology) gives L-Gen a substantial boost in energy efficiency. With a 40 percent increase in energy efficiency ‒ a major improvement over previous generations ‒ the system has the ability to provide building owners and facility managers with increased operational savings without sacrificing occupant comfort.

As the system closes in on the desired target and all indoor units are within 1.8 degrees Fahrenheit of the temperature set point, the system will gradually raise the target evaporating temperature in a linear fashion for more efficient operation. When the system reaches the final target evaporating temperature, the compressor modulates, reducing the power and slowly dialing back the energy required to cool the space. All the while, the occupants continue to receive maximum personalized comfort, and building owners and facility managers notice a reduction in energy consumption and an improvement in operational system longevity. Optional settings are available for baseline evaporating temperatures of 37, 41 and 43 degrees Fahrenheit.

Energy Efficiency 

Although VRF’s initial equipment cost can be higher than that of some traditional systems, the operational costs are often lower because of its industry-leading efficiencies. Mitsubishi Electric’s L-Gen offers a 54 percent increase over previous generations, offering a substantial increase in efficiency and a decrease in operational costs. Specifically, thanks to VRF’s INVERTER-driven compressor, building owners and facility managers can expect to see a savings of up to 25 percent on utility bills.

In a commercial space, like an office building, load and comfort needs vary throughout the summer as outdoor temperatures and indoor capacity fluctuates. However, the reality is that commercial spaces need cooling regardless of the time of day or year and number of people. L-Gen does an impressive job meeting spaces’ and occupants’ needs. It offers a full-range variable capacity to deliver only the amount of conditioning required to match a zone’s cooling demand. Therefore, the system’s ability to zone offers the personalized comfort control that’s necessary to create an enjoyable environment for occupants.

L-Gen Is Available for Your Next Project

In comparison to traditional systems, VRF technology, like L-Gen from Mitsubishi Electric, ultimately makes the cooling season more comfortable for building owners, facility managers and occupants because of its ability to cool spaces quickly and efficiently.
