1. A method of air-conditioning for frozen food packing rooms in refrigeration plants including the cooling, heating and dehumidifying of air in refrigerant-filled lamellar heat exchangers, characterised in that simultaneously there are carried out two separate air recirculation cycles, of which cycle I carried out in the upper part of a room consists in cooling the air in the room in summer time and heating it in winter time to a required temperature by means of fan heat exchangers, while cycle II carried out in the lower part of a room consists in - dehumidifying humid air through drawing the air from the room into a dehumidification unit, in which the air is cooled down and moisture contained in it is frozen out, and subsequently the dehumidified air is heated to a required temperature, and - delivering the dehumidified air to the part of the room where frozen food is packed.3. An air-conditioning system for frozen food packing rooms in refrigeration plants including refrigerant-fed lamellar heat exchangers, a fan, a humid air intake duct and a dehumidified air outlet duct, characterised in that, below the ceiling, in the opposite corners of a room, there are mounted encased heat exchangers (1) connected to the refrigeration system, while by the outer wall of the room...<IMAGE>
