Title:
VENTILATION, DEHUMIDIFICATION AND HEAT RECOVERY APPARATUS
Document Type and Number:
WIPO Patent Application WO2002077536
Kind Code:
B1
Abstract:
The invention relates to an apparatus for air ventilation, drying and heat recovery, consisting of a recuperative (1) and a regenerative (2) heat exchanger and supply and exhaust air flows between indoor and outdoor spaces. The heat of indoor air is transferred to outdoor air in a regenerative heat exchanger (2), and then outdoor air and moist air is led from the indoor space to the recuperative heat exchanger (1). The outdoor air conducted to the recuperative heat exchanger (1) has a temperature such that outdoor air generates condensation, i.e. drying of indoor air in the recuperative heat exchanger (1). After this, dry indoor air is exhausted through the regenerative heat exchanger (2) and warm outdoor air is supplied indoors through the recuperative heat exchanger (1). Owing to this arrangement, indoor air is replaced with outdoor air while indoor air is being dried with free outdoor air, thus providing substantially enhanced air-drying efficiency.
