Evaluation of a ventilation heat pump for small commercial buildings.

Author(s) : MERCER K. B., BRAUN J. E.

Summary

Air-to-air energy recovery can be used to reduce ventilation loads for small commercial buildings. Enthalpy exchangers are one approach to energy recovery that is commonly employed. An alternative technology involves the use of a heat pump that operates between the ventilation and exhaust streams. In the paper, the performance of ventilation heat pump heat recovery unit was studied through simulation. A model of the heat pump was developed and validated using manufacturers' and laboratory test data. This component model was then incorporated within a system simulation to investigate operating cost savings for the heat pump relative to a base case that does not employ energy recovery but utilizes fixed minimum ventilation rates with an enthalpy economizer.
