ERVBBLHA
ENERGY RECOVERY VENTILATORS
Product Data
The Energy Recovery Ventilation (ERV) system offered by Bryant
is the finest on the market today. The ERV provides efficient and
cost effective heat recovery during the heating season when needed
most.
As temperatures drop below 23_F(--5_C), indoor air is recirculated
periodically through the heat exchanger core to prevent frost from
forming. Competitors’ methods of supplementary electric defrost
waste energy. Unlike rotary wheel heat exchangers which mix air
streams, these cross--flow or counterflow heat exchangers ensure
that there is no mixing of the stale air stream with the fresh outdoor
air stream.
A filter installed on the incoming outdoor air stream removes large
airborne particles from the intake air stream before they enter the
heat exchanger and reduces the maintenance required. (A filter is
also installed on the outgoing air stream, up stream of the heat
exchanger core.) The units’ acoustically engineered design makes
the Bryant ERV the quietest on the market and ensures that comfort
is felt, not heard.
Unlatching two (2) suitcase style latches allows easy removal of the
filters and core for cleaning.

METHODS TO SIZE ERVs
METHOD 1
1. Calculate cu ft of occupied space.
2. Multiply by recommended air changes per hr (AC/h).
3. Divide by 60 minutes per hr to convert to CFM.
Example:
2000 sq ft with 8 ft ceiling, 0.35 air changes per hr (AC/h)
(2000 sq ft x 8 ft ceiling x 0.35 AC/h) / 60 min/h = 93.3 CFM
METHOD 2
1. Multiply number of people times 15 CFM/person.
2. Multiply number of bath rooms 20 CFM/each.
3. Add 25 CFM for kitchen.
Example:
2 people, 2 baths, 1 kitchen
(2 x 15) + (2 x 20) + 25 = 95 CFM

The heating load chart shows the heating loads in Btuh for a range
of winter design temperatures for each model of ventilator.
ERVBBLHA
EXAMPLE: The heating design temperature for Little Rock, AR is
20_F. The additional heating load of the ERVBBLHA1200 at
20_F is 559 Btuh. This additional load should be taken into
consideration when sizing the heating equipment.

Cooling Load (Btuh) @ Inside Design Temp
72°F and 50% Relative Humidity
The cooling load chart shows loads in Btuh as well. To use the
cooling load chart, first find the design enthalpy from a
psychrometric chart using the design dry bulb and wet bulb
temperatures. (See pg. 7.) The cooling load can then be found for a
range of enthalpies for each ventilator.
EXAMPLE: The design dry bulb temperature for Miami is 90_F
and the average wet bulb at that temperature is 77_F. Usi n g the
psychrometric chart, the enthalpy is about 40.5 Btu per pound
(Btu/lb) of dry air, which would round up to 41 Btu/lb dry air. In
the left column, at 41 Btu/lb dry air, the ERVBBLHA1200 has an
additional cooling load of 5042 Btuh, while the HRV150CFM unit
has an additional cooling load of 8437 Btuh.

Control features
OneTouch Control:
Allows control of ventilator with the touch of a button. This
control will operate as a main wall control. The OneTouch will
operate the unit in Intermittent Mode (20 minutes per hour),
continuous low speed, continuous high speed, and off.
Latent Control:
Low Exchange Mode—If the relative humidity inside the building
is lower than selected, air exchange would occur with the outside at
high speed. If the relative humidity inside the building is higher
than selected, air exchange would occur with the outside at low
speed. This ensures continuous air exchange for constant air
quality.

Intermittent Mode—If the relative humidity inside the building is
higher than selected, no air exchange would occur and the system
would turn off. If the relative humidity inside the building is lower
than selected, air exchange would occur with outside at high speed.
this mode is ideal for maintaining the proper humidity level when
the continuous mode cannot.
Automatic Defrost Cycle Featur
es
All models offer a non --electric defrost cycle feature which
prevents frost and ice buildup within the heat recovery core. When
the outside air temperature falls below 23_F(--5_C) it is
electronically sensed and the dampers close the outside air ports.
This allows warm indoor air to recirculate within the heat recovery
core. The frequency of this cycle increases as the outside air
temperature decreases.
