Abstract

PURPOSE:To lower the relative humidity in a containing box and to maintain a contained object in a dry state by providing a passage for leading an air supply flow to a room and a damper A for sealing arbitrary one of the passage and an air supply passage on the air supply passage, and providing a communicating port with the air supply passage and a damper B for sealing arbitrarily one of the communicating port and an exhaust passage on the exhaust passage. CONSTITUTION:By sealing a containing box blowout port 14 and a communicating port 27 by a damper A 23 and a damper B 28, respectively, air supply/exhaust air blowers 19, 26 are operated. Outdoor air flows to a room 3 by an air supply passage 17, and air in the room 3 flows outdoors by an exhaust passage 24. In this case, in a heat exchanger 31, sensible heat exchange is executed between an air supply flow 18 and an exhaust flow 25. Subsequently, by sealing a passage 20 and the exhaust passage 24 by the damper A 23 and the damper B 28, respectively, the air supply/exhaust air blowers 19, 26 are operated. Air in the room 3 passes through the heat exchanger 31 from an exhaust grill 29 and becomes a circulating flow 32 and returns to the room 3. On the other hand, outdoor air passes through the heat exchanger 31 from a double tank tube 11 and discharged to a containing box 4. In this case, in the heat exchanger 31, sensible heat exchange is executed between the air supply flow 18 and the circulating flow 32, and discharge of moisture from a contained object is quickened.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention reduces the humidity in a storage cabinet provided in a room of a house for storing futons, etc. by utilizing indoor and outdoor air conditions, and improves the internal walls of the storage cabinet and The present invention relates to a drying device that can prevent condensation on stored items.

[Conventional technology]

Traditionally, storage cabinets for storing futons, etc.
2) As shown in Publication No. 394, warm air heated by an electric heater is blown into the storage to raise the temperature inside the storage to dry the items to be dried such as futons and to prevent condensation on the inner walls of the storage. There are things that can be done to prevent this.

[Problem to be solved by the invention]

Conventional drying equipment like the one above uses an electric heater to raise the temperature inside the storage cabinet, which consumes a lot of power.Heating also increases the absolute humidity, which increases the temperature of the outside air. This results in an increase in the dew point of the inner wall of the storage room that receives the cooling, resulting in a storage room that is prone to condensation.In order to solve this problem, we installed a display on the side wall of the storage room facing the outside air as shown in Figure 5. It is also possible to install a ventilation fan with a built-in air exchanger to provide air supply and exhaust, but according to this, if one condition is taken as an example, as shown in the psychrometric diagram shown in Figure 6, When operating with an indoor temperature of 12°C and a relative humidity of 100% (point A in the figure), and an outdoor air temperature of 0°C and a relative humidity of 90% (point B in the figure), the temperature inside the storage cabinet is 3°C, The relative humidity is 75% (point C in the figure), and there is little margin for dew point temperature against dew condensation. Also,
If a ventilation fan similar to the above is installed on the wall facing the heated room of the storage room as shown in Figure 7, the temperature inside the storage area will be increased by 12 ℃, relative humidity 100% (point A shown), temperature of heated room 20℃
, when operating at a relative humidity of 60% (point B in the diagram), the storage temperature is 15°C and the relative humidity is 82% (point C in the diagram).
As above, the decrease in humidity is slight, and the margin for the dew point on the inner wall of the storage is not large.Furthermore, in the cases of Figs. 5 and 7, the air conditioning action including prevention of condensation inside the storage However, it was impossible to air condition the entire room, and a separate ventilation fan had to be installed.

This invention was made to solve the problem,
By only operating the feeder, the consumption of gravity is small, and the relative humidity inside the storage is kept low to keep stored items dry and not damp, preventing condensation on the inside walls of the storage. The purpose of this invention is to obtain a drying device that can dry a storage compartment and ventilate a room using a ventilation fan.

[Means to solve the problem]

The drying device according to the present invention includes a storage space provided in a room of a house for storing futons, etc., and an air supply provided inside the storage space to form a supply air flow for supplying outdoor air into the storage space. an air supply flow path provided with an air blower; an exhaust flow path provided with an exhaust air blower that is provided to intersect with the air supply flow path and exhaust the exhaust flow from the room to the outdoors; a ventilation unit consisting of a heat exchanger for exchanging sensible heat provided at the intersection with the air supply flow path, a flow path for guiding the air supply flow into the room in the air supply flow path; A damper A is provided to arbitrarily seal any one of the communication channels with the air supply channel, and a damper B is provided to arbitrarily seal any one of the communication port with the air supply channel and the communication port and the exhaust channel. It has been established.

Additionally, the ventilation unit is built into the storage and used as a storage device.

Additionally, a ventilation unit is installed on the ceiling of the storage room.

The inlet for the supply air flow and the outlet for the exhaust air flow are formed by two-layered pipes.

[Effect]

In this invention, a storage is provided in a room provided in a house and stores futons, etc.;
An air supply channel equipped with an air supply blower that forms a supply air flow that supplies outdoor air into the storage room, and an exhaust channel that is installed to intersect with this air supply channel and exhaust the exhaust flow from the room to the outdoors. The ventilation unit includes an exhaust flow path provided with an air blower and a heat exchanger for exchanging sensible heat provided at the intersection of the exhaust flow path and the air supply flow path. A channel for guiding airflow into the room, a damper A for optionally sealing either this channel or the air supply channel, and a communication port with the air supply channel in the exhaust channel, and a communication port between the communication port and the air supply channel. By installing a damper B that arbitrarily seals either of the exhaust flow paths, by moving dampers A and B arbitrarily, sensible heat can be exchanged between the supply air flow and the exhaust flow in the room by the heat exchanger. In addition, in the storage room, outdoor air with low absolute humidity can be supplied to the room by raising the temperature using heat quantity without using an electric heater, and the relative humidity in the storage room is lowered. Power consumption also decreases.

Furthermore, by incorporating the ventilation unit into a storage and using it as a storage device, the ventilation unit can be used as a storage device with no capacity.

Furthermore, by arranging the ventilation unit on the ceiling of the storage, a large storage space can be obtained, and the ventilation unit will not become a clutter.

Furthermore, since the inlet for the air supply flow and the outlet for the exhaust flow are formed using double-layered pipes, only one outdoor duct work is required.
