Heat Recovery Ventilators

The Heat Recovery Ventilation (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.

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 — If the relative humidity inside the building is lower than selected, the ambient air would be 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.

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

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.

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 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 HRVBBLHU1250 would have an additional cooling load of 6428 Btuh. This additional load should be taken into account when sizing the air cooling equipment.
