A system providing for basement or crawlspace ventilation is described. The system allows for a reduction in the relative humidity levels of a basement or crawlspace and an increased basement or crawlspace ventilation. The basement or crawlspace ventilator includes: an inlet, duct and outlet for receiving air from the upper levels of a building and exhausting it into the basement or crawlspace of said building; a basement inlet, duct and outlet for receiving air from the basement or crawlspace and exhausting it to the outside atmosphere; an inlet, duct and outlet for transferring outside air to, and then expelling from a heat exchange core; an inlet, duct and outlet for transferring basement or crawlspace air to and from the heat exchange core; a heat exchange core used to transfer heat from the outside atmosphere to the basement or crawlspace air; and a plurality of fans for forcing ventilation from the upp er levels of the building to the basement or crawlspace and from the basement or crawlspa ce to the outside atmosphere, from the outside atmosphere to the heat exchange cor e, and from the basement or crawlspace to the heat exchange core. |
