A heat pump desiccant unit for dehumidification and humidification.

Author(s) : AYNUR T. N., HWANG Y., RADERMACHER R.

Summary

A novel self-regenerating electric vapour compression heat pump desiccant (HPD) unit is introduced. The HPD unit dehumidifies the outdoor air during ventilation while cooling is needed, and uses only the moisture in the outdoor and return air to humidify the indoors during ventilation when heating is needed, and does not require additional water sources like the conventional humidifiers. It is found that the HPD unit provides and maintains the target indoor humidity ratio of 10 g/kg during the dehumidification mode, and for the humidification mode, it is obtained that, the HPD unit can trap significant amount of return air humidity and add it to the outdoor air.
