HEAT RECOVERY VENTILATORS
Product Data
The Heat Recovery Ventilation (HRV) system offered by Bryant
is the finest on the market today. The HRV 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.
The units’ acoustically engineered design makes the Bryant HRV
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.
HRVBBLHA
NOTE: The HRV should not be installed in an attic or
unconditioned space unless provisions are made for drainline
freezing and condensation.

Control Features
HRV
Basic Control:
Allows the user to manually set fan speed to low or high as
required to maximize comfort.
Standard Control:
Offers automatic dehumidistat control and the option to select
continuous or intermittent fan operation. Setting the wall control
to low will activate the continuous mode.
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.
Automatic Defrost Cycle Features
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.

1. Multiply number of people times 15 CFM/person
2. Multiply number of bathrooms times 20 CFM/each

The heating load chart shows the heating loads in BTUh for a
range of winter design temperatures for each model of ventilator.
EXAMPLE: The heating design temperature for Milwaukee,
WI, is --4_F. At --5_F, the additional heating load of the
HRVBBLHA1250 is 8417 BTUh. This additional load should be
taken into consideration when sizing the heating equipment.
Example: 2 people
2 bathrooms
1 kitchen
(2 x 15) + (2 x 20) + 25 = 95 CFM
Additional heating and cooling load charts
Although the ventilators process the outside air before it enters
the home, additional heating and cooling loads need to be
considered.

The cooling load chart shows the loads in BTUh also. 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 following psychrometric chart.) The cooling
load can then be found for a range of enthalpies for each
ventilator.
EXAMPLE: The cooling design dry bulb temperature for
Milwaukee, WI, is 87_F and the average wet bulb at that
temperature is 73_F. On the psychrometric chart the enthalpy is
about 37.7 BTU/lb of dry air which will round up to 38 BTU/lb
of dry air. In the left column, at 38 BTU/lb the HRVBBLHA1250
would have an additional cooling load of 6428 BTUh. This
additional load should be taken into account when sizing the air
cooling equipment.
