Looking for Garage Ventilation Solutions?

Compartmentalized Ventilation Solutions

Massachusetts's adoption of IECC 2018 has created design challenges to how we traditionally approach multi-unit residential buildings such as apartments, condos, hotels, and dormitories. We will discuss why standards are pushing the market towards new design concepts involving demand control ventilation, energy recovery, and compartmentalization of living spaces.


Specifically, IMC2015 Section 401.2 states that in buildings where the infiltration rate in a dwelling unit is less than 5 air changes per hour each dwelling unit shall be ventilated by mechanical means.


The implication of these changes pose challenges on traditional systems that can be easily overcome by incorporating compartmental energy recovery into your designs.

Aldes Vertical Stack Fan Coil w/ Energy Recovery Core

IQ-VFC


Aldes IQ-VFC is an intelligent ERV-integrated vertical fan coil for high-rise apartments, condominiums, and hotels. The IQ-VFC takes all the benefits of a standard vertical fan coil and builds in the energy-efficient ventilation of an Energy Recovery Ventilator (ERV). The result is a heating, cooling, and ventilation solution that works smarter, saves space, and reduces costs. Now available with NSF-certification.

Airflow and Zone Controls

Aldes Airflow & Zone Control products are designed to introduce flexibility and dynamic control to any central ventilation system. These products correct common ventilation issues such as stack effect and poor airflow balance. Millions of Constant Airflow Regulators (CAR3) have been installed to precisely regulate building ventilation systems, which saves energy by reducing the load placed on heating and cooling systems. The Zone Register Terminal (ZRT) saves additional energy by boosting exhaust ventilation rates only when spaces are occupied, eliminating wasteful ventilation in unoccupied areas.

Aldes Constant Airflow Regulator

CAR3

New CAR3® - Next Generation in Precise Airflow

The new dual adjustable model CAR3 Constant Airflow Regulator is a modulating orifice that automatically regulates airflows in duct systems to constant levels. The passive control element responds to duct pressure and requires no sensors or controls.

The CAR3 compensates for changes in duct pressure caused by: use of demand control solutions, thermal stack effect and dust-clogged filters as an example. The CAR3 provides a low-cost solution to balancing forced-air systems for ventilation, heating, and air conditioning, eliminating the need for on-site balancing. The CAR3 will regulate airflow in supply, return, or exhaust duct systems. The CAR3 is designed to complement ALDES register assemblies or can fit inside standard rigid round ducting, as well as fittings such as take-offs, tees, etc. with a double lip gasket around the circumference ensuring a tight, no-leak fit.

The active control element of the CAR3 is a engineered damper assembly which is calibrated to respond to changes in pressure with no input from an external power source or signal. The CAR3 is UL 2043 safety classified and labeled for flame and smoke generation.

The CAR3 airflow regulators control airflow accurately to within 10% of rated flow throughout the target operating pressure ranges; 0.12 to 1.2 in. w.g. (30 to 300 Pa) for low pressure models (CAR3-L), and 0.4 to 2.8 in. w.g. (100 to 650 Pa) for high pressure models (CAR3-H). Airflow set point is selected by turning the adjustment dial on either side (supply or exhaust) of the CAR3. The indicator shows the selected CFM. Each diameter of CAR3 has a unique airflow range for both low- and high-pressure variants, and the setpoint is infinitely adjustable across those ranges.

Aldes Zone Register Terminal

ZRT

Aldes patented Zone Register Terminal (ZRT®) are designed to introduce flexibility and demand control to central ventilation systems. The multi-zone ZRT® regulates ventilation without need for individual fans. Each ZRT® is a combination grille, register box, control damper, and optional flow regulator(s). This unique combination provides up to four different control schemes without the need for expensive pneumatic, electronic, or DDC control systems. To ensure the proper calibration of the damper assembly, do not exceed 1.0 in. w.g. (250 Pa) of differential pressure across the damper door.


When used in central systems, the ZRT-1 model provides on-off control for on-demand ventilation. This allows fan downsizing and promotes energy savings by minimizing necessary fan horsepower and ventilation-induced heating and cooling loads on the building. The optional Constant Airflow Regulator (CAR3) can be installed in the ZRT-1’s extended duct collar to place a maximum flow limit on each terminal when activated. The automatic operation of the CAR3 will provide precise balancing to each terminal, compensating for intermittent use of other ZRTs around the building, as well as factors like stack-effect.


The ZRT-2 model is used for combination low-flow continuous indoor air quality ventilation and on-demand high-flow spot ventilation using the same central fan system. This is achieved by integrating a minimum Constant Airflow Regulator (CAR3) directly into the damper assembly. When the ZRT-2 is powered on, the control damper powers open, bypassing the low-flow CAR3 to allow the boost ventilation rate set by the maximum flow CAR3 (when equipped).

Pressurization Control Systems

Greenheck Vari-Green Constant Pressure Controller

For Use with Bathroom or Dryer Exhaust

The Constant Pressure control can be used to monitor either the static pressure or velocity pressure in a system. The control will automatically adjust the fan speed to maintain a desired static pressure or velocity pressure (used for constant CFM) in the system. This control will reduce energy consumption not only by reducing the speed and the energy used by the fan, but will also reduce the amount of conditioned air that is exhausted.

LFSystems Active Compensated Stairwell Pressurization System

Listed to UL864

The Active Compensated Stairwell Pressurization System (ACSP) uses the L864 controller to maintain a constant positive pressure in a high-rise building stairwell or multi-zoned area. The L864 includes up to three pressure differential transducers per controller to monitor and control pressure in the pressurized zone. It can also modulate an optional relief damper for precision pressure control.


When the L864 Constant Pressure Controller receives a start command from either the FSCS or manual pull, it monitors pressure in the stairwell and adjusts the speed of the connected supply fan and optional motorized relief damper to maintain setpoint to ensure a safe and tenable environment in the stairwell and adjacent corridor.
