A multipurpose air conditioning apparatus is disclosed. The apparatus comprises fan assemblies (3, 13), a compressor (4), a condenser, an evaporator, a liquid and gas circuit, throttling means, air inlets, air outlets and means for redirecting the air flows. The apparatus is adapted such that the functions as condenser and evaporator are interchangeable for heating of air or cooling of air, respectively, in that the liquid flow in the liquid and gas circuit through the condenser, evaporator and the throttling means is reversible on demand. The apparatus comprises at least two separated units, Main and Annex, each having an air heat exchanger (2, 12), which operates as a combined condenser/evaporator, a fan assembly (3, 13), a fresh air inlet (7a, 17a), a room air inlet (7c, 17c) and a mixing chamber (x, 1x) upstream of the air heating exchangers (2, 12), an air outlet (7b, 17b) downstream of the air heating exchangers (2, 12) and means (9, 10, 19, 20) for redirecting the air flows.
Multipurpose air conditioning apparatus for ventilation, heating of air, and cooling of air, comprising a compressor, fan assemblies, condenser, evaporator, liquid/gas circuit, throttling means, air inlets and air outlets and the apparatus being arranged such that the functions as condenser and evaporator are interchangeable for heating of air or cooling of air, respectively, in that the liquid flow in the liquid/gas circuit through the condenser, evaporator and throttling means is reversible according to requirements, wherein the apparatus comprises at least two separate units, a first main unit and a second annex unit, said units being interconnected via said liquid/gas circuit only, each said unit having a respective air heat exchanger that acts as a combined condenser/evaporator, fan assembly, fresh air inlet, indoor air inlet and mixing chamber upstream of the air heat exchanger, air outlet downstream of the air heat exchanger and independent means for redirecting the air flows;
Method of multipurpose conditioning of indoor air, comprising ventilation, heating of air and cooling of air, in which fan assemblies cause air to flow through a conditioning apparatus that comprises a compressor, condensers, evaporators, liquid/gas circuit, throttling means, air inlets, air outlets and means for redirecting and closing off the air circulation, and in which the flow of liquid/gas can be reversed in order to interchange the functions of the condensers and the evaporators, the method comprising directing outdoor air, indoor air or a mixture of the two to an upstream side of at least two separate units, a main unit and an annex unit, each unit being interconnected via a liquid/gas circuit only, each unit having a respective combined condenser/evaporator, the air is drawn through respective condenser/evaporator by a respective fan assembly, and displaced further at the downstream side of the respective condenser/evaporator, towards a room, the surroundings or both by means of respective, independent redirection means.
A multipurpose air conditioning apparatus for ventilation, heating of air and cooling of air, comprising:
