Versatile VRF

With the ever-changing commercial buildings of today, when choosing an HVAC system, system versatility is key. To get the most out of an HVAC investment, your customers will need systems that can meet their building’s needs today and anticipate what will be needed in the future. At Aireco Advanced Products Group (APG) we have full confidence specifying Variable Refrigerant Flow (VRF) systems as they offer versatility for any job. Below, we highlight three benefits of these superior systems.

Full Range of Unit Styles
Whether your project is Class A office space, a multifamily building or a hotel, you need to cater to aesthetic preferences. You will also need to account for the equipment’s footprint and ductwork to give owners as much leasable space as possible. No worries! Systems like Mitsubishi Electric’s CITY MULTI® have a broad range of indoor units, ducted or ductless that can accommodate any space, style or aesthetic.

Add on Systems Easily
As businesses grow and expand, they may find themselves in a position to add on to their building, whether it be through new construction or renovating a space next to their current facility. With conventional systems, this is often very difficult and adds more time and expense to the construction timeline. VRF’s small, two-pipe system requires minimal, if any ductwork, which makes unit additions simple and streamlined. Not to mention, third-party equipment and unit additions can be easily added to VRF controls, ensuring the building’s comfort can be managed from a single interface.

Custom Controls Offerings
Many VRF manufacturers offer comprehensive system controls services, such as Mitsubishi Electric’s Solutions Group. From the start of a job, these teams can help determine the best controls package for a facility, allowing ease of use and efficiency for facility managers and building owners. This is especially helpful for multifamily buildings where custom tenant billing solutions may be required.

Comfort, Control and Efficiency for Walbrook Mill Apartments

Originally known as Walbrook Mill and Lumber Co., the new Walbrook Mill Apartment Complex is continuing to serve Baltimore’s Coppin Heights community, where the original building operated for over 95 years.

The new, mixed-use complex provides affordable and market-rate apartment rentals and houses retail space for Coppin Heights residents. For this project, building ownership required mechanical systems that were easy to manage, energy efficient and had varying indoor unit options. Together, the APG team, engineer CC Johnson & Malhotra (CCJM) and contractor King Mechanical specified Variable Refrigerant Flow (VRF) technology from Mitsubishi Electric. Below, we talk with Matt Kemp, general manager, APG, about the project and why VRF was an ideal selection.

Tell us a little about the building and what systems were selected.

The building is a new construction, mixed-use development with retail and living space. Mitsubishi Electric’s CITY MULTI VRF system is used in the common areas and retail spaces. The M- and P-Series product lines are installed in the residential units. In addition, we have a PremiSys® DOAS unit bringing in fresh air and Mitsubishi Electric controls. This project definitely showcases their breadth of products.

What are the major benefits of VRF for this building?

All the equipment “speaks the same language” from a communications standpoint. This is super helpful for the owners and operators of the building. They have full comfort control from a single interface and can easily help tenants as needed. Plus you’re reaping the efficiency benefits of VRF systems which is a big draw for tenants.

What are some other unique features associated with Mitsubishi Electric VRF?

One of the best things about choosing VRF technology is that it’s flexible, in a multitude of ways. For example, as time goes on and new retailers come in, building ownership can actually expand their HVAC system very easily with VRF. This is super helpful if a future retailer needs to rearrange the layout of the space. In addition, VRF systems are flexible in that there are many different indoor unit options to fit a variety of needs. In this building, tenant units have ducted air handlers and common areas have ceiling cassettes. You can adjust the system to work for your preferences.
