FIELD: heating.
SUBSTANCE: invention relates to apparatus for waste air heat recovery and for cooling of circulation water (as a cooling tower), as well as for adiabatic cooling and air humidifying in ventilation and air conditioning systems. Heat recovery unit with boiling bed consists of metal casing (1), separator (2), water distributor (3), nozzles (4), movable attachment (5), tray (6), and support grid (7). Additionally guide apparatus and float valve are installed in the casing. Vibrator is installed on the support grid. Attachment is made in the form of hollow balls, with their spherical surface having cut-through screw groove; alternatively, attachment can be made in the form of a screw line, formed on the spherical surface. This attachment's cross-section perpendicular to the screw line, has a profile of circle-type, polygon-type, Berl saddle- or "Italloks" saddle-type.
EFFECT: enhancement of efficiency of waste air heat recovery; expansion of process abilities of device.
