Energy Recovery in Healthcare Facilities

Operating room

The Zero Cross Contamination Solution

The year-round operation of health care facilities and required ventilation rates presents a huge opportunity for energy savings when used in conjunction with energy recovery systems. However, careful consideration must be taken when incorporating these products into the design of health care ventilation systems, due to cross contamination concerns.

ASHRAE Std 170-2013 Ventilation of Health Care Facilities addresses these concerns by requiring a minimum separation of 25 ft (8 m) between outdoor air intakes and exhaust discharges. It further prohibits the use of energy recovery devices in exhaust systems of airborne infectious isolation (AII) and protective environment (PE) rooms unless adequate separation exists between airstreams. In these scenarios, HPT’s split passive energy recovery systems (HRM-V) are best utilized. With an allowable separation of up to 120 ft between exhaust and supply, up to 50% of exhaust energy can be recovered without any risk of contamination.

This same standard does provide an exception to the 25 ft. requirement when Class 1 relief air is utilized. Class 1 air is defined as having little to no contamination or odors than what is found in class 2, 3, or 4. Even under this exception, the energy recovery device must minimize leak potential so that no more than 5% of supply air consists of the exhaust air. Under this scenario, HPT’s side-by-side energy recovery product HRM-H, is utilized. An optional foam filled gap of up to 40” can be incorporated between supply and exhaust for added assurance. This product can also be optimized to recover more energy for the season with the most BTUs and runtime hours and can be configured for airstreams that are in an over-under configuration.
