An energy recovery ventilator (also abbreviated ERV) is a type of air-to-air heat exchanger that not only transfers sensible heat but also latent heat.Because both temperature and moisture are transferred, ERVs can be considered total enthalpic devices.he benefit of using energy recovery is the ability to meet the ASHRAE ventilation & energy standards, while improving indoor air quality and reducing total HVAC equipment capacity.
Introduction. OTV is a MAC-in-IP method that extends Layer 2 connectivity across a transport network infrastructure. OTV uses MAC address-based routing and IP-encapsulated forwarding across a transport network to provide support for applications that require Layer 2 adjacency, such as clusters and virtualization.o effect on existing network design. 1  Transport agnostic: OTV is IP encapsulated and can therefore use any core capable of forwarding IP traffic. 2  OTV therefore does not pose any requirements on the core transport.
