Project Snapshot | Dartmouth College – Konvekta System

Dartmouth LogoThe new existing Burke Hall Chemistry Building was built in the 1950’s. The mechanical systems were renovated in the early 1990’s. A state of the art Konvekta energy recovery system was retrofitted into the system in 2012 to save energy from the 120,000 cfm of exhaust from the labs.

The Konvekta energy recovery system serves four supply air handling units and three exhaust air handling units. In addition to energy recovery the system provides all heating of the 120,000 CFM of supply air. On cold winter days this is achieved with the help of shell and tube heat exchangers that boost the water/glycoltemperature. The plate and frame heat exchangers are fed with steam from the boiler plant.

Operating Performance

During the winter season the Konvekta system will provide nearly 80% of the net heating requirement for the building from energy recovery.  

Konvekta:   Unique Cost Transparency Concerning Energy Efficiency 

Konvekta AG, founded in 1949, is one of the leading manufacturers of air/liquid lamellar heat exchangers.   The heat exchangers are custom designed for each application and manufactured in Switzerland.   They are primarily suitable for utilization in HVAC energy recovery.

The Konvekta system is based on three core elements of a high-efficiency energy recovery system at their disposal: 

Highly efficient heat exchanger

• Hydraulic assembly unit

• System Controller – After installation of a Konvekta heat recovery system the system controller continuously records the system operating parameters and transmits the data via the internet to Konvekta headquarters in Switzerland.  The Syskom software calculates the investment cost as well as the annual operating cost of entire HVAC systems (air-conditioning system, refrigeration plant including re-cooling). Depending on the customer’s interests, the system can be optimized through changes in operating conditions and variations of components. This computing service is free of charge for Konvekta customers.
