Operation of the HRV

These Recirculating Models of HRV's will provide fresh clean air without sacrificing the savings of your energy conserving home. When outdoor air is required for pool room dehumidification, the aluminum cores of the HRV provide effective and efficient heat recovery exchange. Whether operating as an HRV or in recirculation mode, the energy efficient PSC blower motors provide reliable and cost effective operation.

Operation:

Humidity control is provided by an adjustable dehumidistat that is mounted in the pool room. The dehumidistat (supplied and mounted in the pool room in an accessible location 5' above floor level) would be set to a humidity level the operator finds acceptable (for example, in a range of 45 to 55% R.H.). If the humidity level in the room exceeds the setting of the dehumidistat, then outside air is brought into the system and humid air is removed from the room. If a duct heater or hot water coil has been installed in the supply ductwork, this will condition the incoming air.

Control of this heater would be by a duct mounted thermostat. When the humidity level of the room falls to the dehumidistat setpoint, the pool room air is recirculated and no outside air will enter the system. Pool room air moves through the unit, then to the duct heater (optional) and returns to the pool room. Outside air is prevented from entering the unit during recirculation by the supply damper closing off.

The exhaust fan to the outside is shut off during this time. Outside air does not enter the system until the pool room humidity exceeds the setpoint of the dehumidistat.

The unit has an electronically controlled damper door defrost. If the dehumidistat has made its circuit and the unit is drawing in outside air, the defrost cycle will operate as follows:

If the outside temperature drops below 27˚ Fahrenheit (-3 degrees Celsius) the defrost timer is activated. After waiting approximately 27.5 minutes (during which time the core unit may experience some frost build-up) the timer activates the damper door mechanism which closes off the fresh air supply port and opens the defrost port. After approximately 3 minutes the damper door reverses direction and re-opens the fresh air sup- ply port and closes off the defrost port. This cycle repeats until the outside temperature again rises above 27˚ F.

During the defrost cycle, pool room air is moved outside through the unit as well as from the pool room, back to the pool room. To handle the required air flow capacity, two ducts need to be connected to the pool room or one large duct.

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.
