    AIR HANDLING SYSTEM WITH REVERSIBLE RECUPERATOR FIELD OF THE INVENTION
    The present invention relates to an air handling system for transferring thermal energy from a warm air flow to a cold air flow.
    BACKGROUND OF THE INVENTION EP 1 485 657 B1 relates to a heat exchanger for transferring thermal energy from a warm gas flow to a cold gas flow. The heat exchanger of EP 1 485 657 B1 comprises a complicated arrangement of ducts with various connections provided therewith. The heat exchanger further comprises alternating means for temporarily and repeatedly alternating the supply and discharge means on the various connections.
    It is a disadvantage of the arrangement suggested in EP 1 485 657 B1 that the required ducts form a complicated and costly arrangement of flow paths.
    It is an object of embodiments of the present invention to provide a simpler arrangement of ducts.
    BRIEF DESCRIPTION OF THE INVENTION
    The above-mentioned object is complied with by providing, in a first aspect, an air handling system for transferring thermal energy from a warm air flow to a cold air flow, the air handling system comprising 1) a warm and a cold air flow passage comprising respective air inlets and air outlets operatively coupled thereto, 2) a reversible recuperator comprising first and second flow chambers, said first and second flow chambers being adapted to form part of the warm and cold air flow passages in an alternating and repeating manner, and 3) an arrangement for reversing the recuperator in a repeating manner.
    The recuperator of the air handling system of the present invention is preferably mounted in a rotatable manner.
    The recuperator may essentially take the form of a drum or cylinder, and the axis of rotation may coincide with a centre axis of said drum or cylinder.
    It is advantageous of the present invention that the recuperator may the only moving/rotating part. This ensures that the air handling system of the present invention may be implemented in a simple and reliable way.
    The arrangement for reversing the recuperator may comprise an electric motor, such as a servo or a stepper motor. The electric motor is capable of rotating the recuperator in a predetermined manner, such as by rotating it in discrete steps of for example 30 degrees, 60 degrees, 90 degrees, 120 degrees, 150 degrees or 180 degrees about its axis of rotation. The electrical motor may rotate the recuperator directly or via a gearing arrangement. Alternatively, the electrical motor may rotate the recuperator via a belt drive arrangement.
    In a second aspect the present invention relates to a method for operating an air handling system adapted to transfer thermal energy from a warm air flow to a cold air flow, the method comprising the step of repeatedly reversing the operation of a recuperator in order to recycle the humidity.
    In order to ensure a proper recycling of the humidity the recuperator may be reversed at least once every 30 minutes, such as at least once every 15 minutes, such as at least once every 15 minutes, such as least once every 12 minutes, such as least once every 10 minutes, such as least once every 8 minutes, such as least once every 6 minutes. It should be noted that the time between reversing the recuperator is determined using information about temperatures and humidity indoor and outdoor.
    As discussed in relation to the first aspect the recuperator is reversed by rotating the recuperator. Preferably, the recuperator is rotated approximately 180 degrees.
    BRIEF DESCRIPTION OF THE DRAWINGS
    The present invention will now be described in further details with reference to the accompanying figures, wherein
    Fig. 1 shows a first pair of cross-sectional views of the air handling system, and Fig. 2 shows a second pair of cross-sectional views of the air handling system.
    While the invention is susceptible to various modifications and alternative forms specific embodiments have been shown by way of examples in the drawings and will be described in details herein. It should be understood, however, that the invention is not intended to be limited to the particular forms disclosed. Rather, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
    DETAILED DESCRIPTION OF THE INVENTION
    Generally the present invention relates to an air handling system for transferring thermal energy from a warm air flow to a cold air flow. Moreover, the air handling system according to the present invention has a built-in frost protection in that the condensation of water/moisture in the cold air flow channel is counteracted due to a repeated rotation of the recuperator.
    Referring now to Fig. la a front cross-sectional view of the air handling system 100 according to the present invention is depicted. In Fig. 1 warm air is sucked into air inlet 101 and is guided to the rotatable recuperator 105 via air channel 106. The warm air passes the recuperator 105 via chamber 110 (solid line). After the recuperator 105 the now cooled air leaves the air handling system via the air channel 107 and air outlet 102.
    The fresh and cold air to be heated is sucked into air inlet 103 and enters the recuperator 105 via air channel 108. The cold air passes the recuperator 105 via chamber 111 (dotted line). After being heated in the recuperator 105 the air leaves the air handling system via the air channel 109 and the air outlet 104.
    After a certain time period the rotatable recuperator 105 is rotated 180 degrees whereby air channels 106 and 107 becomes connected to air chamber 112 (dotted line) of the recuperator 105, and whereby air channels 108 and 109 becomes connected to air chamber 113 (solid line) of the recuperator 105, cf. Fig. lb. The time period is determined using information about temperatures and humidity indoor and outdoor.
    Thus, by rotating the recuperator 105 the air chambers are exchanged. This exchange of recuperator chambers have a plurality of advantages, among those being 1) frost protection of the air handling system 2) the air handling system is dehumidified due to the reversed air flow
    The rotational behaviour of the recuperator is also illustrated in Fig. 2 which is a side cross-sectional view of the air handling system. In Fig. 2a the recuperator 201 is in a first position, whereas in Fig. 2b the recuperator 205 is in a second position. The difference between the first and second angular positions is 180 degrees in that chamber 202 in Fig. 2a corresponds to chamber 207 in Fig. 2b. Similarly, chamber 203 in Fig. 2a corresponds to chamber 206 in Fig. 2b. The recuperator 201, 205, which preferably takes the form of a drum of cylinder, is rotatable around axis 204, 208, respectively. The direction of rotation may be chosen arbitrary.
