Abstract

Luftbehandlingsanordning (1) innefattande ett luftbehandlingsaggregat (2) med en reglerbar värmeåtervinnare (3) och en värmepump (6) vilken är anordnad för reversibel drift under avfrostning av dess förångare (11,13). Kännetecknade för anordningen är dels att värmepumpens (6) köldmediekrets (7) utbyter energi indirekt med tilluftströmmen (5) och direkt med frånluftströmmen (4), genom att förångaren (11, 13) är anordnad direkt i frånluftströmmen (4) medan värmepumpens kondensor (12) i form av en plattvärmeväxlare (19) är skild från tilluftströmmen (5). En första sida (18) av plattvärmeväxlaren (19) är ansluten mot köldmediekretsen (7) medan en andra sida (20) är ansluten till en köld bära rkrets (15). Köldbärarkretsen (15) innefattar i sin tur ett vätskebatteri (14) i tilluftströmmen (5), en cirkulationspump (17), en reglerventil (22) och en ackumulatortank (21) anordnad för lagring respektive avgivning av uppvärmd köldbärare (16) under icke avfrostning respektive under avfrostning, för minskning av den temperaturdipp som annars uppstår under avfrostning.
