JPS6155530A - Dew inhibiting hot air blast furnace in pechka (russian brick stove) - Google Patents

Abstract

PURPOSE:To decrease a relative humidity in a room to prevent dew condensation and make indoor air fresh by a method wherein dry cold air in winter season is heated and the air is guided into the room through the blast furnace of a pechka. CONSTITUTION:The out-door air is sucked through an opening 10 of a register and fed to the dew condensation inhibiting blast furnace 1 of a pechka through an air feeding duct 5. The air is heated in the blast furnace 1 and the hot air is supplied to each of rooms through ducts by a vertical air supplying passage 8 reaching to an attic. Normal pechka 4 is communicated with collective chimney. The blast furnace 1 has the combustion chamber of the pechka 4 within it and a heating chamber 3 for heating the out-door air. The out-door air entered the heating chamber 3 is passed through a lower chamber 3G and flowed out of the outlet port 3H through the upper chamber 3F and then communicated with the vertical air supplying passage 8.

Description

[Detailed Description of the Invention] L Objective A of the Invention, Industrial Field of Application The present invention provides an air layer in the pot for firewood and coal, takes in dry cold air from outside from below the pot, and turns it into warm air. Change it and send it indoors. This is an attempt to solve the winter condensation problem by lowering the indoor water vapor pressure.

B. Conventional technology and its problems In order for humans to live a healthy life under the winter conditions of northern countries, it is impossible to think without considering the problem of condensation. The scene of people running around with a rag to wipe away the condensation on the windows is a common sight in houses in northern countries. In addition, internal condensation inside the walls makes the glass walls soggy and is a fundamental cause of shortening the lifespan of buildings. Even if the frame of the window glass is changed from aluminum to plastic, it is not at first glance a measure against condensation like wood, but it is only a partial measure against condensation.

10 Configuration of Invention A1 Means to Solve Problem Indoor If the temperature is the same in the room, for example 20°C, the higher the humidity, the higher the dew point dust and the more likely dew condensation will occur. When the relative humidity is 50 parts, the dew point temperature is 9.2 degrees Celsius, whereas when the relative humidity is 70 parts, it is 14.1 degrees Celsius.
Condensation occurs. The water vapor pressure is 8.8 g/m3 when the relative humidity is 1 m3 and 50 parts, and 2.1 g/m3 when the relative humidity is 170 parts.
Also includes m3.

On the other hand, taking Sapporo as an example, the water vapor pressure outdoors in winter in Hokkaido is much lower than that indoors. p.

When the average temperature is -4.5°C, water vapor m2-
3 g/m3 Maximum temperature in summer -1.4℃
z 2-9gc3 Minimum temperature -7.9℃
z l, 7 g/m" (according to the Sapporo Regional Meteorological Observatory) Difference between indoor and outdoor: 20°C - relative temperature 70 - water vapor amount 1'
It contains 2.1 g/m3, while the average outdoor temperature in February is -4.5°C and contains only 2.3 g/m3. This difference is as follows.

12, 1 g/m3-2.3 g/m3= 9.8 g
A difference in water vapor content of as much as /m3 occurs.

21 Means The first problem is that if the low absolute humidity (amount of water vapor) outdoors is utilized and this air is supplied indoors, it will theoretically help to lower the relative humidity (indoors).

However, since the temperature in February is extremely low, averaging -4.5°C in winter, it is problematic to directly introduce outside air into the room. This means that indoor temperatures are expected to drop rapidly. For this reason, there is a way to lower the relative humidity by warming the outside temperature and then introducing dry, fresh air into the room (which only contains 2-3 g/n3 of water vapor at -4.5°C). It is an air tank.

Example 1 of the B0 invention is a ventilation pot for preventing dew condensation for petika (hereinafter simply referred to as ventilation pot) of the present application. Therefore, this ventilation pot 1 is composed of a furnace body 2 located inside and a ventilation can body 6 located outside. That is, - the above-mentioned furnace body 2 is made by piling up fire bricks on top of a base for one size to form a front part 2B, left and right side parts 2C, 2D, and a back part 2E - Furthermore, a top plate part 2F is formed on the upper surface of these parts. is installed - and - this furnace body 2
is connected to a well-known structure 4.

The ventilation can body 3 includes left and right side portions 2C of the furnace body 2,
2D, is configured in a U-shape in plan so as to surround the back part 2E,
A ventilation layer 6' is formed inside. In this case, the ventilation can body 3 may be embedded in the left and right side surfaces and the back surface of the furnace body 2. Further, the ventilation layer 6'' is divided into upper and lower chambers 3F by a horizontal partition plate 6A stretched approximately in the center.

It is partitioned into 3G. Reference numeral 6B is a large cold air hole located in the foundation soil and opened on the lower left side of the lower chamber 6G, and an air supply duct 5 from the outside air is connected to this hole 6B. 6E is a communication port between the upper and lower chambers 6F and 6G opened at the right front of the horizontal partition plate 3A, and 3H is a hot air outlet opened at the back of the upper chamber 3F. It is connected to a vertical air passage 8 that reaches the attic 7 through the attic, and warm air is distributed to each room for mourning through a duct 9 in the attic. Further, the mounting positions of the air supply duct and the register opening may be configured as follows, for example. In other words, a register opening (64 g) is installed at a height of about 2 m to 1.5 m from the outer wall surfaces G and L (in Sapporo, it is set as Kita-no-Tori depending on the wind direction), and a one-bet foundation hole is installed to supply air. Connected by duct. As a result, the average wind speed in February is 2. In the case of l m/s, 30 m3 of outside cold air enters the room through an air layer around the kettle. The transport route is to make a hole in the upper part of the air layer of the kettle, run a duct (possibly brickwork), and raise it to the second floor for distribution. 11 is a collective chimney.

lfl, Effects of the Invention Since the present invention is constructed as described above, the cold winter outside air is passed through the air layer of the heated pot, and the outside air is warmed to about 20" to 35°C. As a result, the dry air outside is warmed and brought indoors, reducing relative humidity and preventing condensation inside the room.In addition, indoor ventilation capacity is promoted. At the same time, by introducing fresh and warm air with an oxygen content of about 21%, which is the same as outside air, a healthy indoor environment (in winter) is created.
can be produced.

In addition, this ventilation method using wind pressure makes it possible to create a house with good ventilation in the summer by considering natural convection in advance. Note that although the above explanation has been given in the case of artificial ventilation, it is natural that artificial ventilation may be used as appropriate.
