Definitions

  • the present invention relates to a dehumidifying apparatus, and more particularly, to a desiccant dehumidifying apparatus. Much more particularly, the present invention relates to a dehumidifying apparatus for recovering much more of the applied heat, thereby reducing power consumption of its heater.
  • Desiccant dehumidifying apparatus refers to a dehumidifying apparatus using a property of a moisture absorbing material for absorbing moisture from air at a room temperature and evaporating moisture at the time of heating-up.
  • a circular desiccant roller is formed of moisture absorbing material. When the desiccant roller rotates, it absorbs moisture from the interior of a system to a predetermined section of the desiccant roller, and discharges the moisture from an other section of the desiccant roller to the exterior of the system, thereby eliminating the moisture from the system.
  • the desiccant dehumidifying apparatus includes a heater for generating heat; a condenser for condensing a moisture holding air using external air; a heat exchanger for exchanging heat between air passing through the condenser and being cooled, and air passing through a hot portion of the desiccant roller and being heated due to its absorption of heat; and a fan for forcing air to flow through an air channel.
  • the heat exchanger exchanges heat between the air absorbing heat and being heated, and the air passing through the condenser and being cooled. Therefore, the air passing through the condenser and getting cold is heated up. Accordingly, even when the heater applies a smaller amount of heat to the air, a high heat is transferred to the desiccant roller, thereby eliminating moisture from the desiccant roller.
  • the conventional dehumidifying apparatus has a disadvantage in that since the air already absorbs heat from the condenser when passing through the condenser, the air has a small temperature difference with the desiccant roller when passing through the desiccant roller, thereby not absorbing much heat from the desiccant roller.
  • the dehumidifying apparatus has a disadvantage in that even when a heat exchange is performed by the heat exchanger, much heat is not recovered by the heat exchanger due to a small difference of temperature of the air facing and the air flowing.
  • the present invention is directed to a desiccant dehumidifying apparatus that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • An object of the present invention is to provide a desiccant dehumidifying apparatus for recovering much more heat of a heater activated in the desiccant dehumidifying apparatus, to reduce its total power consumption.
  • Another object of the present invention is to provide a desiccant dehumidifying apparatus for recovering much more heat of a heater to maintain air of low temperature to be exhausted to an interior space, thereby reducing user's discomfort caused by high temperature air.
  • a another further object of the present invention is to provide a desiccant dehumidifying apparatus for improving a performance of moisture absorption.
  • a dehumidifying apparatus including: a desiccant dehumidifying unit; a recovery channel positioned to pass air through a first section of the desiccant dehumidifying unit, for evaporating and condensing moisture of the desiccant dehumidifying unit; a first inlet channel positioned to pass air through a second section of the desiccant dehumidifying unit, for allowing air to flow therethrough and eliminating moisture from the air; and a second inlet channel positioned to directly introduce external air to pass through a third section of the desiccant dehumidifying unit, for recovering heat of the desiccant dehumidifying unit.
  • a dehumidifying apparatus including: a main body; a desiccant dehumidifying unit housed within the main body; a condenser for condensing air, which passes through a dry section of the desiccant dehumidifying unit and retains moisture; a first inlet channel positioned to pass air through the condenser and a moisture absorption section of the desiccant dehumidifying unit, for allowing air to flow therethrough and eliminating moisture from the air; a second inlet channel positioned to directly introduce external air to pass through a heat recovery section of the desiccant dehumidifying unit, for allowing air to flow therethrough and recovering heat from the air; a heat exchanger in which the air in the first inlet channel and the second inlet channel and passing through the desiccant dehumidifying unit flow to one side of the heat exchanger, and in which the air passing through the condenser flows to an other side of the heat exchanges, thereby ex
  • a dehumidifying apparatus including: a desiccant dehumidifying unit for absorbing or evaporating moisture depending on temperature; a moisture absorption section provided at the desiccant dehumidifying unit, for receiving external air and eliminating moisture from the air; a dry section provided at the desiccant dehumidifying unit, for evaporating moisture absorbed in the moisture absorption section, using heated air; and a heat recovery section provided at the desiccant dehumidifying unit, for recovering heat applied to the dry section, using cold air directly introduced to the desiccant dehumidifying unit from the exterior.
  • the present invention has an effect of reduction of power consumption, and has an advantage in that the air discharged from the desiccant dehumidifying apparatus to an interior space can be decreased in temperature, so that a user's sense of comfort can be promoted.
  • FIG. 1 is a view illustrating a construction of a desiccant dehumidifying apparatus according to the present invention.
  • FIG. 2 is a plan view illustrating a dehumidification roller installed in a desiccant dehumidifying apparatus according to the present invention.
  • FIG. 1 is a view illustrating a construction of a desiccant dehumidifying apparatus according to the present invention.
  • the inventive desiccant dehumidifying apparatus includes a main body 1 for forming an exterior of the dehumidifying apparatus and having a plurality of parts installed therein; and a condensation water collector 2 disposed at a lower side of the main body 1 for collecting water resulting from dehumidification, from the main body 1 .
  • a dehumidification roller 3 formed of desiccant material is provided in the main body 1 and performs a rotational motion.
  • the dehumidification roller 3 retains moisture in a room temperature environment, and emits the retained moisture in a high temperature environment.
  • the dehumidification roller 3 is partitioned into three sections. The sections are shown in FIG. 2 illustrating a plan view of the dehumidification roller.
  • the dehumidification roller 3 is partitioned into a moisture absorption section 31 , a dry section 32 , and a heat recovery section 33 .
  • the moisture absorption section 31 absorbs moisture from the room temperature air.
  • the dry section 32 evaporates moisture, which is held by the dehumidification roller 3 when the air passes through the moisture absorption section 31 , using heat.
  • the heat recovery section 33 recovers heat applied from the dry section 32 to the dehumidification roller 3 .
  • Each of the sections 31 , 32 and 33 is not fixed to a specific portion of the dehumidification roller 3 , but is provided at each specific portion of the dehumidification roller 3 depending on its relative position with respect to the main body 1 when the dehumidification roller 3 rotates.
  • a roller is shown in FIGS. 1 and 2 the present invention is applicable to and includes different shapes of desiccant members such as for example cylindrical rollers or belts.
  • Air suitable for allowing the sections 31 , 32 and 33 to perform their functions passes through each of the sections 31 , 32 and 33 .
  • a state of air flowing through the sections 31 , 32 and 33 will be described later.
  • the inventive dehumidifying apparatus includes a recovery channel 20 forming a closed loop and circulating air in the main body 1 ; a first inlet channel 8 and a second inlet channel 9 for introducing external air requiring dehumidification; and an outlet channel 11 for discharging the dehumidified air from the main body 1 to the exterior of the system.
  • a low temperature and high humidity air is introduced through the first inlet channel 8 from the exterior of the system. After that, the low temperature and high humidity air passes through a condenser 6 so that a high temperature and high humidity air flowing through one duct of the condenser 6 is condensed.
  • the air of the first inlet channel 8 flows through the condenser 6 , the air is changed to a middle temperature and high humidity air due to its absorbed latent heat of condensation.
  • the air passes through the moisture absorption section 31 of the dehumidification roller 3 so that the air is changed to a middle temperature and low humidity air due to its eliminated moisture.
  • the middle temperature and low humidity air is introduced into and heat-exchanged in a heat exchanger 7 so that the air is further reduced in temperature due to its thermal loss.
  • the resultant air is discharged through a dehumidification ventilator 10 and the outlet channel 11 to the exterior of the system. It will be easily expected that the dehumidification ventilator 10 forms a negative pressure region, thereby introducing the air from the exterior of the system to the interior of the main body 1 .
  • a low temperature and high humidity air is introduced into the main body 1 through the second inlet channel 9 .
  • the introduced air passes through the heat recovery section 33 of the dehumidification roller 3 , not passing through the condenser 6 so that the air is changed to a high temperature and high humidity air.
  • the specific portion of the dehumidification roller 3 already absorbing heat when the air passes through the dry section 32 is positioned at the heat recovery section 33 , the air passing through the heat recovery section 33 via the second inlet channel 9 can be changed to a high temperature and high humidity air.
  • the resultant air is introduced into the heat exchanger 7 .
  • the air flowing through the first inlet channel 8 is changed to a middle temperature and low humidity air
  • the air flowing through the second inlet channel 9 is changed to a high temperature and high humidity air. Therefore, when both are mixed, the mixed air is changed to a high temperature and low humidity air at the intersection of the first and second inlet channels 8 and 9 .
  • the air flowing through the first and second inlet channels 8 and 9 are suitably just controlled in amount, the air can be also controlled to any one between a state of high temperature and low humidity and a state of middle temperature and middle humidity.
  • it is hereinafter assumed that the air is controlled to the state of high temperature and low humidity.
  • the air flows through the heat exchanger 7 , the air is changed to a low temperature and low humidity air due to thermal loss, and the resultant air is discharged to the exterior of the system via the dehumidification ventilator 10 and the outlet channel 11 .
  • the heat exchanger 7 absorbs heat from the air passing through the inlet channels 8 and 9 , and changes the air to a middle temperature and low humidity air. After that, the resultant air is guided to and ventilated through the recovery ventilator 4 .
  • the air passes through the heater 5 , the air is changed to a high temperature and low humidity air.
  • the air is introduced to the dry section 32 of the dehumidification roller 3 to allow moisture of the dehumidification roller 3 to be evaporated into the air.
  • the air passes through the dry section 32 of the dehumidification roller 3 , the air is changed to a high temperature and high humidity air, and the resultant air is introduced into the condenser 6 .
  • the air decreases a little in temperature due to its absorption of latent heat of moisture, thereby continuously maintaining the air at a high temperature.
  • the high temperature and high humidity air passes through the condenser 6 , it is heat-exchanged with the low temperature and high humidity air flowing through the first inlet channel 8 , and is condensed. Therefore, the high temperature and high humidity air is changed to a low temperature and low humidity air due to its loss of moisture, and the resultant air is introduced into the heat exchanger 7 .
  • the low temperature and low humidity air flows through the heat exchanger 7 , it is heat-exchanged with the high temperature and low humidity air, which passes through the heat exchanger 7 within the first and second inlet channels 8 and 9 , and is changed to a middle temperature and low humidity air.
  • the resultant air is again introduced into the recovery ventilator 4 .
  • the present invention is characterized in that the air introduced into the heat exchanger 7 can be changed in temperature and humidity owing to existence of the second inlet channel 9 .
  • a mixture of the air guided through the first and second inlet channels 8 and 9 is introduced into the heat exchanger 7 .
  • the user can suitably control amounts of the air flowing through the first and second inlet channels 8 and 9 , thereby controlling a state of the air as desired.
  • the air flowing through the first and second inlet channels 8 and 9 can be also suitably controlled in amount (for example by suitable air valves) to control the air to be in any state between a state of the high temperature and low humidity air and a state of the middle temperature and middle humidity air.
  • This state can be variably formed between the state of the middle temperature and low humidity air flowing through the first inlet channel 8 and the state of the high temperature and high humidity air flowing through the second inlet channel 9 .
  • the air increases in temperature to recover a large amount of heat in the dehumidification roller 3 , and decreases in humidity to eliminate a larger amount of moisture from the dehumidification roller 3 .
  • the air introduced into the heat exchanger 7 can be promoted to be in an atmosphere of low humidity, but disadvantageously decreases in temperature. Therefore, the above state is undesirable in the following respects. Since the heat exchanger 7 does not recover a large amount of heat, the heater 5 needs to apply a large amount of heat, thereby increasing power consumption of the main body 1 . Further, since the heat exchanger 7 is deteriorated in efficiency, dew condensation occurs in an inlet duct disposed toward the recovery ventilator 4 . Furthermore, a larger amount of heat of the heater 5 is not recovered and is discharged through the outlet channel 11 , thereby causing user discomfort and inconvenience.
  • the amount of the air introduced through the first and second inlet channels 8 and 9 is suitably controlled. It is desirable that the air is controlled to be in any state depending on an installation environment of the dehumidifying apparatus.
  • the air passing through the moisture absorption section 31 and the air passing through the heat recovery section 33 can be also independently varied in amount in such a manner that different fans are respectively used to introduce the air into the first and second inlet channels 8 and 9 .
  • the air passing through the moisture absorption section 31 and the air passing through the heat recovery section 33 can be also independently varied in amount in such a manner that different fans are respectively used to introduce the air into the first and second inlet channels 8 and 9 .
  • a larger amount of air is introduced into the first inlet channel 8 , a larger amount of moisture can be absorbed by the moisture absorption section 31 and therefore, an entire performance of the dehumidifying apparatus can be improved.
  • the air flowing through the first and second inlet channels 8 and 9 are suitably controlled in amount considering the above relation, the heat of the heater 5 is sufficiently recovered almost without degrading a performance of dehumidification. Accordingly, the power consumption is reduced, and less dew condensation occurs in the inlet duct disposed at a side of the recovery ventilator 4 , and the performance of moisture absorption of the dehumidification roller 3 is improved, thereby improving the performance of dehumidification of the dehumidifying apparatus, and the heat is prevented from being dissipated from the main body 1 , thereby reducing user displeasure and discomfort.
  • the air flowing through the first and second inlet channels 8 and 9 can be set to an amount ratio of 80% to 20%. In such a flow environment, an optimal driving state of the dehumidifying apparatus can be realized without degrading the performance of dehumidification.
  • the air flowing through the first and second inlet channels 8 and 9 can be also variably controlled in amount, thereby additionally enhancing user convenience.
  • the air flowing through the second inlet channel 9 can be increased in amount.
  • the air flowing through the first inlet channel 8 is increased in amount, thereby improving the performance of dehumidification.
  • predetermined valves for controlling the amounts of the air flowing through each of the inlet channels 8 and 9 can be installed at any one or both of the inlet channels 8 and 9 or at any appropriate location along the inlet channels 8 and/or 9 .
  • Such valves or dampers can be manually operated or can be controlled in any appropriate fashion.
  • the condensation water collector 2 is detachable, thereby conveniently eliminating water resulting from dehumidification.
  • the inventive desiccant dehumidifying apparatus has advantages in that much more of the heat of the heater can be recovered, thereby totally reducing the power consumption of the dehumidifying apparatus, and the performance of moisture absorption is improved, thereby enhancing an efficiency of dehumidification, and the heat emitted to the exterior of the system is reduced, thereby decreasing user's displeasure.
  • the inventive desiccant dehumidifying apparatus has an advantage in that the dehumidifying apparatus is prevented from being dew-laden at its duct, thereby reducing a concern about trouble, which can be caused during the operation of the dehumidifying apparatus.
