Estimating the term…
A hand-portable drying apparatus and method for use in a damp or waterlogged room, the apparatus including a housing having a carrying handle, the housing containing first and second airflow ducts arranged generally parallel to each other and having respective air inlet and air outlet ends, the apparatus further including means to force air through the ducts and to selectively heat it in at least one of the ducts, and valve means within the housing to selectively direct air from the first duct to the second duct whereby to move air from within the room received by the first duct back to the room via the second duct or to expel air from the room via the first duct to outside the room and draw in fresh air from outside the room via the second duct.
A hand-portable drying apparatus for use in a damp or waterlogged room, the apparatus including a housing having a carrying handle, the housing containing first and second airflow ducts arranged generally parallel to each other and having respective air inlet and air outlet ends, the apparatus further including one or more fans force air through the ducts and a heater to selectively heat the air in at least one of the ducts, and a valve within the housing to selectively direct air from the first duct to the second duct whereby to move air from within the room received by the first duct back to the room via the second duct or to expel air from the room via the first duct to outside the room and draw in fresh air from outside the room via the second duct.
Apparatus for drying a room comprising first and second airflow ducts within a housing, the ducts being switchable by a valve for, in a first mode, introducing fresh air from without the room being dried and exhausting air from within the room via first and second fans and, in a second mode, closing the valve to thereafter recirculate air within the room until a given level of humidity has been reached or a given time period has elapsed, and a heater downstream of the first fan for selectively heating the air in the room, the apparatus further including a regulator to adjust the speed of the first and/or second fans to vary the airflow over the heater to thereby increase the temperature within the room as required.
A method of drying a room including the steps of providing a heater and first and second airflow ducting and associated first and second airflow fans in a first mode, for selectively introducing fresh air from without the room being dried and exhausting heated air from within the room being dried, and in a second mode selectively recirculating heated air within the room while substantially preventing ingress or egress of air into or from the room, sensing the temperature and/or relative humidity within the room, and adjusting the airflow of the first and/or second fans in response to an indication that a required parameter has not been reached or has been exceeded when the apparatus is operating in the second mode.
Room drying apparatus which includes a fan and associated ducting for introducing ambient air into the room, recirculating it within the room and sequentially exhausting the recirculated air from the room after a sensed condition of air within the room has been reached, the apparatus further comprising a valve which prevents ambient air from entering the room via the apparatus when the fan is operating to exhaust air from the room so that a negative pressure occurs in the room.
