Description

Constant temperature dehumidification drying device {CONSTANT TEMPERATURE DEHUMIDIFICATION AND DRYING APPARATUS}

The present invention relates to a constant temperature dehumidifying and drying apparatus that maintains a constant temperature of air discharged to an indoor side and removes moisture contained in the air to form an indoor environment in a constant temperature dehumidification and dry state.

In general, when the humidity in the air increases, the discomfort index increases and adversely affects health. Moreover, in the case of indoors, when the humidity is high, it adversely affects the living environment, such as mold growth or the increase of harmful insects that like high humidity.

Humidity can be divided into absolute humidity and relative humidity, which means the absolute amount of water vapor contained in the air. Relative humidity refers to the amount of water vapor in the atmosphere relative to the amount of saturated water vapor at the current temperature.

On the other hand, in order to make the indoor air comfortable, it is appropriate to maintain the relative humidity of about 40% to 60%. That is, as the amount of saturated water vapor increases or the amount of water vapor in the atmosphere decreases, the relative humidity decreases.Since the amount of saturated water vapor increases with temperature, heating the air can increase the amount of saturated water vapor, thereby lowering the relative humidity. have.

In addition, in order to lower the relative humidity, moisture in the air may be directly removed. In this way, an equipment that creates comfortable air by controlling the relative humidity in a way that directly removes the moisture is referred to as a dehumidifying device.

Document 1 uses the waste heat generated during the condensation of the refrigerant while maintaining a constant temperature in the constant temperature dehumidification chamber using a refrigerant, and uses the waste heat generated from the condenser for reheating (secondary condenser). By redistributing the refrigerant to the 1st and 2nd reheating units at a certain rate, the moisture in the air that passed through the heat exchanger is heated again and contacts the heat exchanger to promote condensation again, so that a low humidity effect can be obtained with low operating cost. , Finally, as the air entering the room that needs low humidity is heated again, the relative humidity is extremely low, so that various kinds of seed storage, old book storage, medicine storage, etc., where various ultra-low humidity constant temperature maintenance is required can be economically operated. It is a technology related to the dehumidification device.

As another technology, Korean Patent Registration No. 10-2055644 (registered on December 9, 2019, hereinafter referred to as'document 2') 『automatic constant temperature dehumidification device』 is proposed.

It is connected to the cooling side of the regenerator and the cooling side of the regenerator is connected to one of the condensers through a wind pipe, so that cooling by external air or other cooling sources is not required by controlling the temperature by itself, and a closed drying process can be realized. It is a technology related to an automatic constant temperature dehumidification device that satisfies the large air volume demand of wet sludge drying electricity by designing a circulation air volume without dehumidification by separating the circulating air volume and dehumidifying air volume without emitting odor during the sludge drying process.
