Summary

This article is the Spanish translation of a paper presented at the 12th International Refrigeration and Air Conditioning Conference, Purdue University, USA (see the Bulletin of the IIR, reference 2010-2005). The effects of the ventilation and the control mode on the performance of the variable refrigerant volume (VRV) system integrated with a heat recovery ventilation (HRV) were field-tested in both cooling and heating seasons in an office suite. It was found that, for both cooling and heating seasons, the VRV system in the individual control mode provided better thermal comfort than the VRV system in the master control mode. It was also observed that the HRV system increased the indoor humidity ratio in the cooling season by introducing the high humidity outdoor air to the indoors, resulting in a humid indoor environment. On the other hand, it decreased the indoor humidity ratio in the heating season by introducing the low humidity outdoor air to the indoors, resulting in a dry indoor environment. Due to the additional ventilation load, the ventilation assisted VRV system consumed higher energy than the non-ventilated VRV system.
