[Industrial applications]

 The present invention relates to a heating and cooling system for a house by forced air convection that warms in winter and cools in summer without using any special heat and cold sources.

[0002]

[Prior art]

 As a healthy house, various structures have been developed for the purpose of effectively using underfloor air in the summer and solar heat in the attic for heating and cooling the house in the winter, as well as various air-conditioning systems for the house. Most of the structure of the house where air is convected throughout the house is due to natural convection of air using thermal expansion of air. Therefore, due to the low coefficient of thermal expansion of air and the poor airtightness at the time of construction, the air convection effect did not increase and the heating and cooling effect of the house was low. In addition, even in the case of a heating and cooling system for a house that uses a ventilation fan, the effect is only expected to be felt through elementary and partial use, and the entire house was made to fully utilize these heat and cold sources. However, it was insufficient as an effective air conditioner.

[0003]

[Issues to be solved by the device]

 The problem to be solved is that in order to effectively use the underfloor cold air in summer and the solar heat in the attic in winter to heat and cool the house, air convection to the whole house and release and circulation of air, inflow and shutoff Can not be controlled effectively, and can not respond to the local environment of the house, such as the concrete display of the heating and cooling effect that does not depend on the user's experience and the size of the house and the climate.

[0004]

[Means for Solving the Problems]

 In order to effectively carry out air convection to the whole house, the present invention automatically operates an air-blowing fan with an appropriate air volume based on temperature difference data using a computer for the temperatures of the underfloor space and the attic space. The most important feature is operation control. In addition, in order to effectively release and circulate, inflow, and block indoor air, the summer and winter are recognized based on the outside temperature data, and the opening and closing of the underfloor ventilation opening and indoor air release Automatically control switching of circulation. In addition, the automatic operation control of the air supply fan based on the humidity data of the underfloor space ensures that there is always a temperature difference and a humidity difference between the underfloor space and the attic space, regardless of the local environment of the house such as the size of the house or the climate. It has become possible to maintain a low level, and a device that can check the heating and cooling effect on a digital display has been realized.

【Example】

 In a house with a structure in which the underfloor space of the house and the attic space are connected by the air passage 1 in the wall of the house or a ventilation duct, and air is convected throughout the house, the air in the attic space is discharged from the intake duct 2 to the outside and An air supply fan 3 capable of supplying air to the underfloor space, an air discharge duct 4, and a circulation duct 5 are provided. The duct is equipped with a ventilation switching damper and an electric opening / closing damper 7 in the ventilation opening under the floor. Three temperature sensors 8, 9 and 10 for measuring the temperature of the underfloor space, the temperature of the attic space and the outdoor temperature are provided, and a humidity sensor 11 is provided between the underfloor space. The temperature measured by the outdoor temperature sensor 10 is processed by the computer 13 in the control panel 12, and the dampers 6 and 7 are controlled based on the temperature data. The electric opening / closing damper 7 and the ventilation switching damper 6 of the discharge duct 4 to the outside are closed, and the ventilation switching damper 6 of the circulation duct 5 under the floor is opened. If the temperature is equal to or higher than the set temperature, the electric opening / closing damper 7 for the underfloor ventilation opening and the ventilation switching damper 6 for the discharge duct 4 are opened, and the ventilation switching damper 6 for the circulation duct 5 under the floor is closed. The computer 13 compares and processes the temperature measured by the temperature sensor 8 in the underfloor space and the temperature measured by the temperature sensor 9 in the attic space, and sends the temperature difference data based on the calculated temperature difference data. The air fan 3 is automatically operated and controlled, and when the temperature difference is equal to or higher than the set temperature, the air supply fan 3 automatically operates, and when the temperature difference is restored, the air fan 3 is automatically stopped. Furthermore, the humidity measured by the humidity sensor 11 in the underfloor space is processed by the computer 13, the air blower fan 3 is automatically controlled based on the humidity data, and when the set humidity is exceeded, it is converted into temperature difference data. Operates with priority and stops when the set humidity is restored. Further, the measured temperature and humidity are digitally displayed on the control panel 12. A system for cooling and heating a house by forced air convection, which allows the basic data of the above computer arithmetic processing to be changed arbitrarily and also has the function of being manually operable.

[Effect of the present invention]

 The feature of the present invention is that a computer is used to automatically control the air supply fan based on the temperature difference data between the underfloor space temperature and the attic space temperature of the house and the humidity data. This is a cooling and heating system for houses using forced air convection, which was used for controlling the dampers that open and close the dampers and the ventilation ducts for releasing air inside the house and circulating ducts under the floor. In the summer, the hot air in the attic space, which is heated by the sun, is released to the outdoors from the exhaust duct by an air-blowing fan, and the underfloor cold air is guided to the attic space from the air passage in the wall, and the underfloor space temperature and the attic space temperature are Keeping the whole house cool by eliminating the temperature difference. In winter, the warm air in the attic space heated by solar heat is guided from the circulation duct to the underfloor space by an air-sending fan and circulated throughout the house, eliminating the temperature difference between the underfloor space temperature and the attic space temperature. , Keep the whole house warm. The present invention automatically controls the air blower fan based on temperature difference data and humidity data processed by a computer, so that the entire house is comfortable and healthy regardless of the local environment such as house size and climate. The stable space with little temperature / humidity change, which is indispensable to the environment, and the heat retention and dew-proof property are realized, and the effective cooling and heating effect can be exhibited. This is a heating and cooling system for a house that uses forced air convection to visually confirm not only the air-conditioning and heating effects by digitally displaying the humidity and humidity.
