The present invention relates to an air temperature conversion supply device. Specifically, the air of the present invention is supplied through the air flow pipe supply port and discharged through the outlet port. That is, the inside of the air flow pipe generates a continuous air flow. For effective air flow, a fan is mounted inside the air flow pipe, and air flow energy can be added by rotation of the fan. In addition, a heat transfer unit may be mounted adjacent to the fan of the air flow pipe. The heat transfer unit supplies heat or recovers heat to generate a temperature increase or decrease. Therefore, since the temperature of the air passing through the air flow pipe can be changed by the operation of the heat transfer unit, outdoor air can be changed to a desired temperature. As a more specific embodiment, the inside of a person's living space should be periodically discharged with carbon dioxide and supplied with fresh oxygen. For this purpose, indoor air must be exhausted and outdoor air must be supplied. However, if there is a difference between indoor and outdoor temperatures, heat loss may result. In order to prevent this, indoor exhaust air and outdoor supply air flow separately through separate air flow pipes, and heat loss of the indoor supply air must be compensated for using heat from the outdoor exhaust air. The heat exchange is performed by a heat recovery unit, and the heat recovery unit is formed as a heat exchanger. Preferably, it is good to use a plate type heat exchanger.

The discharge air flow pipe and the supply air flow pipe must be closed or the flow path is changed as necessary. To realize this, the exhaust air flow pipe and the supply air flow pipe form a recombination plate using a plurality of diaphragms. Some of the diaphragms form openings, and the openings mount the first dampers. The first damper is closed, but if necessary, it must be opened by the operation of the first damper controller. Specifically, when indoor air is not discharged to the outside and only foreign substances in the air are to be removed through internal circulation, an air circulation mode may be formed by opening an opening between the supply air flow pipe and the discharge air flow pipe.

Supply air and discharge air flow through respective flow pipes (exhaust air flow pipe and supply air flow pipe). Flowing air can be thermally balanced through a heat exchanger to recover some of the energy. However, the air passing through the heat exchanger may cause unnecessary flow resistance and unnecessary temperature exchange. In order to solve this problem, the flow pipe is installed by dividing a pipe passing through the heat exchanger and a pipe bypassing the heat exchanger. The bypass pipe is made through an air whirlpool pipe. Also, each of the exhaust air flow pipe and the supply air flow pipe may communicate with each other. This is selectively performed according to the operation mode of the air temperature converter. To control the flow direction of air, a second damper is mounted on the air swirl pipe, and the second damper is operated by a signal from the second damper controller.

Supply air may contain a high moisture content. In order to remove moisture from the air, the prior art added a separate dehumidifying filter, lowered the air temperature, or added a separate dehumidifying device. These devices have the disadvantage of incurring additional equipment and energy consumption. To solve this problem, a moisture absorbent is applied to the surface of the heat transfer unit, and the flowing air can deodorize only moisture by contacting the moisture absorbent. Since the moisture adsorbent adsorbs and aggregates moisture in the air, moisture is not included in the flowing air. The condensed water condensed from the moisture adsorbent is received in the condensed water collection container under the heat transfer unit, and when a certain amount of the condensed water is received, it is automatically discharged.

Supply air and exhaust air generate flow energy by fan rotation. The fan is rotated by the driving force of the electric motor. Since the electric motor generates a constant frequency, it becomes a cause of inducing vibration, which can cause resonance. In particular, the box-type temperature conversion device may additionally generate ringing noise according to resonance. In order to solve this problem, the fan motor may be combined with the temperature conversion device through an anti-vibration mount or may be installed in a separate device outside the temperature conversion device. When the fan motor is externally mounted, only the rotating shaft of the fan motor is connected to the inside of the temperature converter to rotate the fan. At this time, the rotating shaft is equipped with a coupling for damping. The fan motor may mount a plurality of fans on one rotating shaft.
