Abstract

PURPOSE:To improve habitability by a method wherein in summer season, hot air within an attic is discharged and cold air from an under-floor part is sent to the attic from one duct and in turn in winter season, the hot air within the attic is sent from the other duct to the under-floor space and the cold air at the under-floor space is sent to the attic from one duct to control a temperature within the housing. CONSTITUTION:In summer season, as a temperature within an attic 2 is increased up to a predetermined temperature by solar heat, a switch is turned ON by a thermo- sensor 11. Discharging fans 4 and 4 and a fan 9 are operated and hot air within the attic 2 is discharged by fans 4 and 4. Air at the under-floor space 3 is sent to the attic 2 by the fan 9. In winter season, a temperature of the attic 2 is increased by the solar heat. As the temperature reaches a predetermined value, the switch is turned ON by the thermo-sensor 11, fans 9 and 10 for the ducts 7 and 8 are operated. The hot air within the attic 2 passes through a duct 6, is sent to the under-floor space 3. The cold air within the under-floor space 3 passes through a duct 7 and is blown to the attic 2. As the temperature within the attic 2 is less than the predetermined temperature, the switch is turned OFF by the thermo-sensor 11, the fans 9 and 10 are stopped and ventilation of the hot air and cold air is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a temperature control method for a house having a normal structure having an attic and an underfloor area.

[Prior Art] Generally, the room temperature of a house in the summer is controlled using a cooling device, and in the winter, the room temperature is controlled using a heating device.

[Problems to be Solved by the Invention] Temperature control using the above-mentioned air-conditioning equipment is extremely efficient on a room-by-room basis, but it is considered inappropriate for controlling the temperature as a whole in a house partitioned by walls, fittings, etc. ing. For this reason, the temperature inside a house during summer and winter varies from room to room depending on whether an air conditioning system is installed or not, and the temperature difference is large, which may result in poor livability.

In addition, in a two-story house, there is a difference in room temperature between the upper and lower floors.
On the upper floors, the temperature in the attic rises due to the sunlight shining directly on the roof, which causes the room temperature on the upper floors to be higher than on the lower floors. This rise in room temperature due to solar heat is particularly noticeable in military equipment, and the efficiency of air conditioning equipment decreases on midsummer days.

An object of the present invention is to provide a new temperature control method that can reduce the humidity level inside a house due to solar heat in the summer and use the solar heat to increase the temperature inside the house in the winter.

[Means for Solving the Problems 1] This invention according to the above object provides an exhaust fan at a required location in the attic of a house, and also provides a ventilation hole under the floor that can be freely opened and closed, so that the underfloor and the attic are connected. Multiple ducts equipped with fans communicate with each other. In the summer, hot air from the attic is exhausted outdoors by the exhaust fan, while cool air from under the floor is blown into the attic from one duct, and during the winter, the other duct The above problem is solved by controlling the temperature inside the house by blowing warm air from the back of the house to the attic and blowing cold air from under the floor to the attic from one duct.

[Example 1 1 in the figure is a two-story house having an attic 2 and a basement 3,
Install the required number of exhaust fans under the eaves of the attic 2 4.4. are provided at regular intervals, and ventilation holes 5.5 are provided at required locations under the floor 3 so as to be openable and closable, so that outside air can freely flow into the underfloor 3 when opened.

The attic 2 and the underfloor 3 are communicated by a duct 7.8 provided through the partition wall 6, and the duct 7.8 is equipped with a fan 9.10 on the underfloor side.

Also, in the attic, there is a thermosensor 11 that operates the above-mentioned exhaust fan 7.
is arranged.

Note that 12 is the ventilation duct for room 13 on the upper floor, and duct 7
It is a branch from 14 is a living room on the lower floor.

Next, temperature control will be explained.

Temperature control in summer (Fig. 1) The temperature detection value of the thermosensor 11 is set in advance by a control unit installed in one of the rooms,
Ventilation holes 5.5 under the floor 3 are left open.

When the temperature in the attic 2 rises to the set temperature due to solar heat,
When the thermo sensor 11 turns the switch ONL, the exhaust fans 4, 4 and the fan 9 operate, and the fan 4.4 exhausts the hot air from the attic 2 to the outside, and the fan 9 exhausts the air from the under-floor 3 side. Air is blown to attic 2.

Normally, the air under the floor 3 is colder and colder than the outside air, so
The temperature in the attic 2 is lowered by the air flow, and the temperature in the living room 13 on the second floor is controlled to rise due to the hot air in the attic. Moreover, the air under the floor 3 is taken in through the ventilation hole 5.5 and supplied as air to the attic. In this case, opening only the ventilation holes on the north side to take in air will increase cooling efficiency.

When the temperature in the attic 2 falls below the set temperature, the thermo sensor 11 turns off the switch and the exhaust fan 4
．． 4 and fan 9 stop, and the exhaust and ventilation of the shed @3 are stopped. Therefore, temperature control is performed every time the temperature in the attic 2 reaches the set temperature.

Temperature control in winter (Figure 2) Close the ventilation holes 5.5 under the floor 3, and set the thermosensor 11 in the shed @2 to a predetermined temperature.

When the temperature in the attic 2 rises due to solar heat and reaches the set temperature, the thermo sensor 11 turns on the switch.
The fans 9, 10 of the duct 7.8 are activated.

As a result, warm air in the attic 2 is blown to the underfloor 3 through the duct 6, and cold air in the underfloor 3 is blown to the attic 2 through the duct 7. When the temperature in the attic 2 falls below the set temperature, the thermosensor 11 turns the switch to 0FFL, stopping the fans 9 and 10 and stopping ventilation of hot and cold air.

Due to this ventilation, the temperature under the floor 3 increases, the cold from the underfloor side is alleviated, and the lower floor becomes warmer as well. Moreover, the cold air sent to the attic 2 is warmed by solar heat, and is again blown to the underfloor side.

[Effects of the Invention] As described above, in the summer, hot air from the attic is exhausted to the outdoors by an exhaust fan installed in the attic, and from one duct that communicates between the attic and the underfloor. Cold air from under the floor is blown into the attic, and in winter, warm air from the back of the hut is blown from the other duct to the attic, and cold air from under the floor is blown from one duct to the attic to control the temperature inside the house. Because of this, the temperature inside the house during the day can be maintained lower in the summer and higher in the winter than in conventional houses, improving livability, especially in houses with iron roofs. The cooling effect in summer is great, the efficiency of air conditioners is high, and depending on the region, the period of use of air conditioners is shortened.

In addition, the equipment is simple, as all you need to do is install an exhaust fan at the required location in the attic, install a ventilation hole under the floor that can be opened and closed, and connect the underfloor and the above-mentioned small +ta with multiple ducts equipped with fans. There is no need to make any major changes to the structure of existing houses, so it has the advantage of being widely applicable to ordinary houses.
