Ventilation and IAQ

1. Do nothing and rely on windows and leakage to exhaust odors, contaminants and moisture.

2. Use spot fans to intermittently ventilate bathrooms.

3. Use central ventilation systems to intermittently ventilate bathrooms (and other trouble areas).

1. Do nothing and rely on windows and leakage to change air in to/out of the home.

2. Introduce fresh air into the home through a forced air system intermittently by way of a damper or HRV/ERV.

3. Introduce fresh air into the home through a forced air system continuously by way of a High Efficiency AHU with DC motor control.

Ventilation Options (spot) IAQ Options (air changes)

Ineffective (especially in tightly sealed energy efficient homes)

Ineffective (especially in tightly sealed energy efficient homes)

Loud, inefficient, multiple roof penetrations for exhaust

Intermittent provision of fresh air, inefficient, somewhat effective

Silent, efficient, effective, one roof penetration for exhaust (but still need IAQ)

Continuous removal of air from common areas (but still need bathroom exhaust)

ALDES Balanced Continuous Ventilation

HRV Connected to HVAC System

1. Conditioned air is removed from the common areas of the home through the HVAC return.

2. The conditioned air is then used to treat the incoming fresh air which is then distributed through the home using the supply ducts.

• The bathrooms still need ventilation

• The air change is intermittent

• A separate control interlink must be added to meet ASHRAE 62.2

AHU

Continuous Ventilation with Energy Recovery Ventilator

Stale humid air is continuously removed from the bathrooms and kitchen and then used to condition

the fresh air being brought in.

The conditioned fresh air is fed back into the house.

Fresh air is brought into the HRV/ERV from outside the house

Stale air (containing odors, mold causing

moisture and VOC’s) is exhausted from the

house!

Continuous Ventilation with HRV and On Demand Boost

1. Each Bathroom has a motorized damper with a self balancing Continuous Airflow Regulator integrated in the door of the damper. This provides continuous low airflow

in accordance with ASHRAE 62.2

2. When someone flips the light switch or timer, the damper door opens and boosts the fan so that high volumes of stale air are removed from the bathroom during use.

1. ZRT in continuous ventilation mode, the

damper is closed and the pressure independent/self balancing CAR is holding a steady flow of air.

2. ZRT in demand mode, the damper is

open and a micro-switch triggers the fan to boost to high volume evacuation.

An optional 2nd Constant Airflow Regulator may be added in the neck of the ZRT to provide a maximum flow rate while in demand mode operation.

Airflow ControlThe Constant Airflow Regulator “CAR” is the simple solution to balanced airflow.

• Automatically Balances Airflow• Pressure Independent• Factory Calibrated• Easy Field Adjustable• Simple - Plug and Play Install• Maintenance Free• Controls Airflow for Exhaust, Supply & Return Ducts • Save Energy & Increase Comfort• Improve IAQ “One of the greatest

HVAC innovations ever!”

air quality made simple

Airflow ControlThe Constant Airflow Regulator is able to hold a very consistent airflow across a broad range of air pressures.

As the air pressure increase the CAR is engineered to restrict airflow to maintain a

consistent CFM.

Makeup air systems replace the “amount” of air ventilated from a home with “fresh” air from

outdoors.

Makeup Air Solutions

The 3 most common “controlled” methodsfor introducing fresh air are: Air Inlets HRV/ERV/Fan Make-up Air Through The HVAC

ASHRAE 62.2 specifies the effective air change rate as:

Occupancy Rate (# bedrooms +1) = 7.5 cfm/person

Plus Area Rate = 1 cfm/100 sq.ft.

Air Inlets– Negative pressure created by mechanical

ventilation draws a controlled amount of fresh air into living spaces at the most beneficial locations.

Makeup Air Solutions

Compared to having air randomly leak into a

home through uncontrolled cracks Air Inlets:

– Improve Energy Efficiency

– Provide Cleaner Air (think about air coming under a door or through an attic/garage)

– Provide Greater Comfort by controlling airflow amounts

air quality made simple

Air Inlets Should Be Used With:– Continuous exhaust ventilation systems– Radiant baseboard or floor heated spaces– Energy efficient “weatherized” buildings

Makeup Air Solutions

Air Inlets Should Not Be Used With:– Forced-air heating (unless supply & return are well balanced)

– When outside air is considered unhealthy

If forced air heating is available, the FCU or AHU can provide outside makeup air through a fresh air

intake into the return duct.

Precautions

• Air is only introduced while the FCU or AHU is running.

• There is a potential of negatively impacting the performance of or damaging the forced air system.
