Hybrid desiccant dehumidifying apparatus and control method thereof

Abstract

Disclosed are a hybrid desiccant dehumidifying apparatus and a control method thereof which are employed under poor environment, such as a ship painting field. External air cooled by an evaporator is dehumidified and heated while passing through a desiccant dehumidifier and external air heated by condensation heat of a condenser is supplied to the desiccant dehumidifier as a regeneration air source such that high-temperature and high-humidity regeneration. A cooler is integrally formed with the desiccant dehumidifier so that the hybrid desiccant dehumidifying apparatus is manufactured in a compact size and the operating cost thereof is significantly reduced.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a hybrid desiccant dehumidifying apparatus and a control method thereof. More particularly, the present invention relates to a hybrid desiccant dehumidifying apparatus and a control method thereof which can be employed under poor environment, such as a ship painting field, in which external air pre-cooled by an evaporator is dehumidified and heated while passing through a desiccant dehumidifier and external air heated by condensation heat of a condenser is supplied to the desiccant dehumidifier as a regeneration air source such that high-temperature and high-humidity regeneration air can be exhausted to the outside through the heat exchange reaction, and in which a cooler is integrally formed with the desiccant dehumidifier so that the hybrid desiccant dehumidifying apparatus can be manufactured in a compact size and the operating cost thereof can be significantly reduced.[0003]2.

AI Technical Summary

Benefits of technology

[0014]Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a hybrid desiccant dehumidifying apparatus and a control method thereof which can be employed under poor environment, such as a ship painting field, in which external air pre-cooled by an evaporator of a pneumatic cooler is dehumidified and heated while passing through a desiccant dehumidifier and the external air heated by condensation heat of a condenser is supplied to the desiccant dehumidifier as a regeneration air source such that the external air can be dehumidified and heated through the heat exchange reaction, and in which a cooler is integrally formed with the desiccant dehumidifier so that the hybrid desiccant dehumidifying apparatus can be manufactured in a compact size and the operating cost thereof can be significantly reduced.

[0016]A filter is installed at an inlet side of the evaporator and an eliminator is installed at an outlet side of the evaporator so that condensing water contained in the external air can be easily removed without being scattered.

[0020]As mentioned above, the present invention can provide the hybrid desiccant dehumidifying apparatus and the control method thereof which can be employed under poor environment, such as a ship painting field or a working field where dangerous materials are treated and circuited air cannot be reused, in which external air can be pre-cooled by the evaporator or dehumidified and heated by condensation heat of the condenser. Thus, even if the circulated air cannot be reused, the condensation heat of the condenser can be used as the heat source of the desiccant dehumidifying apparatus so that energy consumption can be reduced and the temperature and the humidity can be properly maintained.

Problems solved by technology

In general, the temperature for condensing the humidity is lower than the temperature available during the air conditioning operation, so over-cooled air may be exhausted to the interior of the room, causing unpleasant to the users.

However, in the case of a duct type air conditioning system, a separate heat source is required.

Meanwhile, the conventional air conditioning system is unsuitable for poor environment, such as a ship painting field or a working place where dangerous materials are treated and circulated air cannot be reused.

In addition, since the circulated air cannot be reused, the cooling and dehumidifying apparatus must be operated for a long period of time to properly set the temperature and humidity, so that energy consumption is increased.
