Heat Recovery Ventilators

Form No. PDS HRV.71.1

The Heat RecoveryVentilation (HRV) system offered by Bryant

is the ﬁnest unit on the market today.

The HRVB 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 them the

quietest on the market and ensures that comfort is felt, not

heard.

Unlatching 2 suitcase style latches allows easy removal of the

ﬁlters and core for cleaning.

FEATURES

• Energy saving defrost cycle

• Cross ﬂow, counterﬂow heat exchangers

• Two ﬁlters on incoming outdoor air stream to protect the HRV

core

• Acoustical design

• No-tools maintenance

• Polypropylene heat exchanger core

CONTROL FEATURES

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.

Automatic Control:

In addition to the features found with standard control, this package offers a recirculation mode.

These controls may only be used to operate stand-alone units with the defrost option which enables the recirculation

feature.

* Air exchange with outside.

† No air exchange with outside.

‡ Use only on units with defrost.

CONTROL DESCRIPTION AND USAGE

Fan Speed Control

— Enables user to modulate fan speed from low to high air exchange with outside.

Dehumidistat Control

— Allows the user to select the relative humidity level at which the unit would change fan speed

for dehumidiﬁcation in the winter months.

Continuous Mode

— If the relative humidity inside the building is lower than selected, air exchange occurs with the

outside at low speed.If the relative humidity inside the house is higher than selected, air exchange occurs with the

outside at high speed. Ensures continuous air exchange for constant air quality.

Intermittent Mode

— If the relative humidity inside the building is lower than selected, no air exchange occurs and the

system turns off. If the relative humidity inside the house is higher than selected, air exchange occurs with the outside

at high speed. Ensures minimum air exchange level when the building is unoccupied to minimize operating costs.

Circulation Mode

—Ifthe relativehumidity insidethebuildingislowerthanselected,the ambient airwouldbe circulated

and ﬁltered at high speed.If the relative humidity inside the house is higher than selected, air exchange would occur with

the outside at high speed. Ensures continuous movement and ﬁltration of air for maximum comfort. Available with

automatic control only.

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.

* All defrost times are in the standard mode (as shipped)

† Time between defrost when within speciﬁed temperature range

METHODS TO SIZE HRV’S

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

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.

HEATING LOAD BTU

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

HRVBBLHU1250 is 8417 Btuh.This additional load should be taken into consideration when sizing the

heating equipment.

COOLING LOAD BTU

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 psychrometric chart on p.11.) 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

temperatureis73°F.Onthepsychrometric chart the enthalpyisabout37.7Btu/lbofdry air which will round

up to 38 Btu/lb of dry air.In the left column, at 38 Btu/lb the HRVBBLHU1250 would have an additional

cooling load of 6428 Btuh.This additional load should be taken into account when sizing the air cooling

equipment.
