Abstract

A thermally insulated access door installation (10) of a door (11) which is mounted in a frame (12) for defining an access opening to a refrigerated or cooled storage space, and which comprises: a pair of upright frame members (12) which are horizontally spaced apart to define opposed sides of the required access opening; a double-walled flexible curtain (11) which forms a closure door which can be raised and lowered between closed and open positions with respect to the access opening, and with a space (15) defined between the front and rear walls (13, 14) of the curtain (11); guide means (16, 17) provided on the upright frame members (12) and engaging the side edges of the front and rear walls (13, 14) of the curtain (11), for guiding the raising and lowering movement of the curtain; a blower (18) communicating with the space (15) defined between the front and rear walls (13, 14) of the curtain to deliver a supply of dry or at least low humidity air at a temperature greater than the temperature prevailing in the storage space; and ducts or passages provided in the upright frame members (12) and communicating with the space (15) between the front and rear walls (13, 14) of the flexible curtain (11), when the latter is in the closed position, in order also to receive said supply of air.
