How Does an Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV) Work?

ACT’s Heat Pipe Heat Recovery Ventilator (HRV) is a complete, filtered ventilation system that incorporates an outside air supply fan and a building’s existing air exhaust fan. The goal is to achieve a continuous supply of fresh air into an occupied building while exhausting an equal amount of potentially stale, contaminated air. ACT-HP-HRV is critical in promoting healthy Indoor Air Quality (IAQ) levels.

ACT HP-HRVs provide sustainable “sensible” heat recovery. ACT’s HP-HRVs are designed using high-performance, zero maintenance heat pipe heat exchanger technology. Each unit utilizes the highly efficient ACT heat pipe heat exchanger core and is built and tested to AHRI Standards specifically for end-use applications of commercial buildings. In the winter season, the fresh incoming air stream is tempered by the energy that is transferred from the exhaust air stream. The reverse occurs in the summer. The hot incoming outside air stream is tempered by the air-conditioned cool exhaust airstream saving thousands of BTUs an hour. The result is a passive, energy-saving solution that greatly reduces electrical utility loads while providing a healthier indoor air environment.

Which Climates are ERV or HRV systems most beneficial?

ACT-HP-HRV systems are most beneficial in colder climates that have longer indoor heating seasons; and, in hotter, dryer climates like the Southwest USA. The highest savings occur when there is a large temperature difference between the incoming and exiting air streams. Two other important parameters are the velocity of the airflow and the size of the HRV. Many HRV installations have payback periods as short as one season of operation. ACT-HP-HRVs feature low-pressure drop, passive energy savings and are offered for applications in the 300 to 2,700 cfm range (PDF product specification sheet). Custom units can be designed and built for larger systems, up to 100,000 cfm. 

HRV System Options

Where desired, a tilt control feature can be added to the HRV to enhance the energy transfer depending upon the season. This same tilting mechanism is often utilized as a frost protection system during periods of extreme cold. A PLC or the building’s energy management system can be easily employed to activate the tilt mechanism so that frost build-up is avoided. ACT-HP-HRV system features both filtered intake and exhaust streams with individual fan speed controls for airflow balancing. The HRV system has a low profile allowing for raised flooring or drop ceiling installations. Heavy-duty mounting rings are provided on all models for ease of ceiling installation.

What makes ACT’s HRV Systems better than the competition?
