Integrating run-around heat exchanger systems into the design of large office buildings.

Author(s) : DHITAL P., BESANT R. W., SCHOENAU G. J.

Summary

The effect of using run-around heat exchanger systems on energy use and the energy life-cycle cost of a typical large office building has been investigated. The run-around heat exchanger system was used for both preheating and precooling the supply ventilation outdoor air. The performance of the building using run-around systems was studied using the DOE-2.1D program. The results show that, compared to the energy performance of the building without the run-around systems, the use of run-around heat exchanger systems in the office building can reduce annual electrical energy consumption, natural gas consumption, and total energy costs. Boiler and chiller sizes can be reduced. It was also found that, through the use of run-around systems, the ventilation rate into the building can be increased by several hundred percent without increasing energy costs.
