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.

The Bryant HRVBBB series, comprising the HRVBBLHU, HRVBBLVU, and HRVBBSVC models, represents a significant advancement in the realm of residential heat recovery ventilation systems. Designed to enhance indoor air quality while optimizing energy efficiency, these units cater to a variety of home sizes and layouts, ensuring that residents can enjoy a comfortable living environment year-round.

One of the standout features of the HRVBB series is its heat recovery mechanism. These units effectively capture heat from outgoing stale air and transfer it to incoming fresh air, reducing the energy required for heating or cooling. This process not only decreases utility costs but also promotes an environmentally friendly approach to indoor climate control. The use of high-efficiency counterflow heat exchangers ensures maximum heat transfer, allowing homeowners to benefit from significant energy savings.

In terms of operational characteristics, the HRVBB models are equipped with variable speed motors that allow for customizable airflow settings. This flexibility means that users can adjust the system to meet their specific ventilation needs, whether it’s a larger gathering or routine everyday living. Quiet operation is another highlight; the Bryant HRVBB series has been designed to minimize noise, ensuring that comfort isn’t compromised by disruptive sounds.

Additionally, user-friendly controls are a key feature. The units support easy integration with smart home systems, enabling remote monitoring and adjustments via smartphones or tablets. This connectivity allows homeowners to operate their ventilation systems efficiently, even when they're not at home.

The durability and build quality of Bryant products are well-regarded, and the HRVBB series is no exception. Constructed with high-grade materials, these units are designed to withstand the rigors of everyday use while maintaining optimal performance levels.

In conclusion, the Bryant HRVBBLHU, HRVBBLVU, and HRVBBSVC ventilation systems exemplify modern heating and ventilation technologies. With their focus on energy efficiency, customizable operation, and superior air quality management, these units not only meet the demands of contemporary living but also contribute to a healthier indoor environment. Whether it’s for a family home or a compact living space, the HRVBB series stands out as a reliable choice for homeowners looking to enhance comfort while being energy-conscious.
