Calculation, System Installation | Lifebreath 1000RHCAC specification

Calculation

Note: As a general rule, if the water temperature is maintained at 80˚F and the pool room air temperature is maintained at 82˚F, use a factor of 1 cfm/sq ft of pool surface or .5 cfm/sq ft of room area (whichever is greater) to determine amount of ventilation required.

Example:

Pool surface area		16’ x 32’ (512 sq ft)
*Indoor design air temperature		83 ˚F
Pool water temperature	81 ˚F
Relative Humidity		50 %
*Outdoor design air temperature		15 ˚F

*Always use design temperatures for indoor and outdoor air temperatures. Outdoor design temperatures are published by organizations such as ASHRAE. Do not us day to day temperatures for this calculation.

1. From Table 1, select the appropriate evaporation rate based on the room air temperature, water temperature, and relative humidity.

Evaporation Rate = 0.052

2.From Table 2, select the corresponding flowrate factor depending on the indoor air temperature, outdoor temperature, and room relative humidity.

Flowrate Factor = 21.70

3.Multiply the values obtained from step 1 and step 2 to obtain the minimum CFM required per square foot of pool surface area.

Evaporation rate	X	Flowrate	=	CFM / square foot of water surface area
0.052	X	21.70	=	1.12

4.Multiply the value in step 3 by the area of the pool

Area of pool	X	Value for step 3	=	CFM
512	X	1.12	=	573

System Installation

It is necessary to design and size the duct distribution system for both the supply and the exhaust air streams.

Proper duct design will

•

Minimize air flow requirements

Ensure a comfortable environment by using reheat if required

Optimize humidity control, including eliminating condensation on windows by blanketing the windows with airflow

Please refer to sketch 1 and 2 for typical duct layouts.

1200DDPOOL, 700DDPOOL, 1000RHCAC, 1000RHC specifications

Lifebreath is a brand renowned for its commitment to energy-efficient indoor air quality solutions. Among their offerings, the Lifebreath 700DDPOOL, 1200DDPOOL, 1000RHCAC, and 1000RHC stand out as exemplary products designed for various residential and commercial settings. These units leverage cutting-edge technologies to provide superior ventilation, heat recovery, and air quality management.

The Lifebreath 700DDPOOL is specifically designed for indoor pools and similar environments. This model boasts dual-flow ventilation, which simultaneously circulates fresh air into the space while expelling stale air. The 700DDPOOL features a built-in dehumidistat, ensuring optimal humidity levels are maintained, which is vital for preventing mold and preserving air quality. Its energy recovery capabilities make it an eco-friendly choice, reclaiming heat from exhaust air to pre-condition incoming air, thus significantly reducing heating costs.

The Lifebreath 1200DDPOOL offers similar benefits but on a larger scale. With a higher airflow capacity, the 1200DDPOOL is ideal for larger pool areas or heavily used commercial spaces. It also incorporates advanced filtration technologies that trap allergens, dust, and pollutants, resulting in cleaner air. Both the 700DDPOOL and 1200DDPOOL are engineered for easy installation and maintenance, with features like removable filters and accessible components.

The Lifebreath 1000RHCAC and 1000RHC models shift focus towards whole-home ventilation and air conditioning solutions. The 1000RHCAC combines heat recovery with air conditioning capabilities, allowing for year-round climate control. The unit’s heat exchanger efficiently recovers heat from the outgoing air and transfers it to the incoming air, ensuring that energy is conserved even during cooling seasons.

In contrast, the Lifebreath 1000RHC emphasizes effective heat recovery without an integrated air conditioning system, making it an excellent choice for areas where cooling is not a priority. Both models boast a quiet operation, ensuring no disruption to daily living, along with energy-efficient certifications that appeal to eco-conscious consumers.

Overall, Lifebreath’s 700DDPOOL, 1200DDPOOL, 1000RHCAC, and 1000RHC models provide exceptional performance, versatility, and user-friendly features. These air management systems represent the future of sustainable indoor air quality solutions, meeting diverse ventilation needs while prioritizing energy efficiency and comfort. With Lifebreath, users can breathe easier knowing they have invested in cutting-edge technology designed for health and efficiency.
