Energy Recovery Ventilator
Product Data
The Heat Recovery Ventilation (HRV) and Energy Recovery
Ventilator (ERV) systems offered by Bryant are the finest on the
market today. These units provide 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 make Bryant ventilators 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.
NOTE: The HRV should not be installed in an attic or
unconditioned space unless provisions are made for drain line
freezing and condensation.

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.

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 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.

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. 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. U sing t he
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 HRV1150CFM
unit has an additional cooling load of 8437 Btuh.
