According to the present invention, there is provided an air-conditioning / ventilating apparatus provided in a house in which a lower part of a living space and a space under the floor communicate with each other. Having a first air discharge suction port disposed in the air conditioner, a second air discharge suction port disposed in the underfloor space, an air conditioner, and a heat exchanger for exchanging heat between air supply and exhaust. The apparatus performs reversible discharge of suction air from the first air discharge suction port from the second air discharge suction port and discharge of suction air from the second air discharge suction port from the first air discharge suction port. A suction / discharge device, and discharges the air discharged from the air conditioner, the discharge air supplied from the ventilator, and the discharge air from the suction / discharge device from the first air discharge / suction port in the summer, and performs air conditioning in the season except summer. The discharge air of the device, the discharge air supply of the ventilation device, and the discharge air of the suction discharge device Providing underground temperature utilizing the air-conditioning ventilator housing, characterized in that the discharge from the second air outlet suction opening.

[0005] In the air-conditioning ventilation system utilizing the underground temperature of the house according to the present invention, the discharge air supply and the suction discharge device of the ventilation device which are heated by exchanging heat with the exhaust gas which is higher in temperature than the outside air in the fall season are heated. (1) The warm air above the living space sucked from the air discharge suction port is discharged into the underfloor space, and if necessary, only the indoor unit of the air conditioner is operated to discharge the warm air above the house into the underfloor space. The discharge air supply of the ventilator, which is heated by exchanging heat with the high-temperature exhaust gas, the warm air above the living space sucked from the first air discharge suction port by the suction discharge device, and the discharge warm air of the air conditioner. Since it discharges into the underfloor space and stores heat in the underfloor of the floor, it is easier than the air temperature control system of Japanese Patent No. 2711511 which discharges warm air near the ceiling of the living room to the underfloor space during the autumn and winter days. Store much more heat in the floor It can be. Therefore, the underground temperature utilizing air-conditioning ventilator according to the present invention can more effectively suppress the drop in the room temperature during the autumn and winter nights than the underground temperature utilizing air-conditioning device of the house of Japanese Patent No. 2711511.

[0006] Since it takes time for the temperature change on the ground surface to be transmitted to the deep underground, the temperature change in the ground at a large depth of about 5 m from the ground surface, both outdoors and under the floor, is the temperature change on the outdoor ground surface. About six months later. As a result, deep underground temperatures, both outdoors and under the floor, decrease in summer and increase in winter. The temperature change in the ground at a shallow depth of less than 1 m from the ground surface, both outdoors and under the floor, is substantially synchronized with the temperature change on the outdoor ground surface. In the air-conditioning ventilation system utilizing the underground temperature of the house according to the present invention, in the fall and winter, the warm air discharged from the ventilator and the warm air in the upper part of the living space heated by the heat obtained by solar radiation are sent to the underfloor space to continue. Since the heat is temporarily stored in the underfloor, the temperature decrease between the underfloor soil and the shallow-depth floor due to the seasonal transition from summer to winter is delayed, and the underfloor soil and the shallow-deep underfloor that rise in the summer are reduced. Temperature can be carried over to winter. In the west of the southern Kanto region, the temperature between the underfloor soil and the shallow depth of the subfloor, which rose in the summer, and the temperature of the underfloor soil at the shallow to mid-depth level are raised to the highest in winter. The same as the deep underground temperature
A large heat storage layer extending between the underfloor soil and the underfloor can be formed in winter. The winter temperature in the deep ground 5m below the ground is as high as about 18 degrees west of the southern Kanto region. In the west of the southern Kanto region, the temperature of the underfloor space is maintained at a comfortable temperature in winter by the large thermal storage layer, and the temperature of the living space is maintained at a comfortable temperature. Furthermore, if the warm air discharged from the air conditioner is discharged to the underfloor space in winter and heat is stored between the underfloor soil and the underfloor, the temperature of the underfloor space and thus the temperature of the living space can be maintained at a more comfortable temperature. In cold regions,
By discharging the warm air discharged from the air conditioner into the underfloor space in winter, it is cooler than west of the southern Kanto area, but has the highest annual temperature in winter. Heat can be stored by adding to the heat carried over from the summer season in the floor ground of mid-depth. As a result, in a cold region, the temperature of the underfloor space is maintained at a comfortable temperature in winter by the heat storage between the underfloor soil and the ground floor at a shallow to medium depth, and the temperature of the living space is maintained at the comfortable temperature. . In the air-conditioning ventilation system utilizing the underground temperature of a house according to the present invention, heat is stored in the underfloor by discharging warm air from the living space to the underfloor space, and the underfloor space temperature due to the heat stored in the underfloor.

In summer, when the indoor temperature is lower than the outside air temperature, a downdraft is generated indoors. Therefore, if cool air is discharged from the upper part of the living space, the cool air rides on the downdraft and spreads throughout the living space. During seasons other than summer, when the indoor temperature is higher than the outside air temperature, rising air currents are generated indoors, so if warm air and air supply are discharged to the underfloor space, the warm air and air supply will ride on the rising air flow and spread throughout the living space. Go around.

As described above, in the air-conditioning ventilation system utilizing the underground temperature of a house according to the present invention, the discharge air supply of the ventilation system which is heated by exchanging heat with the exhaust gas having a higher temperature than the outside air in the autumn is heated. And the warm air above the living space sucked from the first air discharge suction port by the suction / discharge device is discharged to the underfloor space, and if necessary, only the indoor unit of the air conditioner is operated to release the warm air from the upper house to the underfloor space. And the warm air above the living space that the suction and discharge device sucks from the first air discharge suction port, Since the warm air discharged from the air conditioner is discharged to the underfloor space and heat is stored in the underfloor, the hot air in the vicinity of the ceiling of the living room is simply discharged to the underfloor space during the autumn and winter days. Much more heat than air conditioners utilizing medium temperatures It is possible to heat storage in the base.
Therefore, the underground temperature utilizing air-conditioning ventilator according to the present invention can more effectively suppress the drop in the room temperature during the autumn and winter nights than the underground temperature utilizing air-conditioning device of the house of Japanese Patent No. 2711511.

In the air-conditioning ventilation system utilizing the underground temperature of the house according to the present invention, the warm air discharged from the ventilator and the warm air above the living space heated by the heat obtained by the solar radiation are sent to the underfloor space in the fall and winter. And heat is continuously stored in the floor,
By delaying the temperature decrease between the underfloor soil and the shallow depth of the floor under the seasonal transition from summer to winter, the temperature between the underfloor soil and the shallow depth of the underfloor raised in the summer can be carried over to winter. In the west of the southern Kanto region, the temperature between the underfloor soil and the shallow depth of the subfloor, which rose in the summer, and the temperature of the underfloor soil at the shallow to mid-depth level are raised to the highest in winter. A large thermal storage layer extending between the underfloor soil and the underfloor can be formed in winter at the same temperature as the deep underfloor temperature. The winter temperature in the deep ground 5m below the ground is as high as about 18 degrees west of the southern Kanto region. In the west of the southern Kanto region, the temperature of the underfloor space is maintained at a comfortable temperature in winter by the large thermal storage layer, and the temperature of the living space is maintained at a comfortable temperature. Furthermore, if the warm air discharged from the air conditioner is discharged to the underfloor space in winter and heat is stored between the underfloor soil and the underfloor, the temperature of the underfloor space and thus the temperature of the living space can be maintained at a more comfortable temperature. In cold regions, the warm air discharged from the air conditioner is discharged into the underfloor space in winter, which is supported by the heat storage in the deep underfloor, which is colder than west of the southern Kanto area but has the highest annual temperature in winter in winter. Heat can be stored in the ground under the floor and in the ground floor at a shallow to medium depth by adding to the heat carried over from the summer. As a result, in a cold region, the temperature of the underfloor space is maintained at a comfortable temperature in winter by the heat storage between the underfloor soil and the ground floor at a shallow to medium depth, and the temperature of the living space is maintained at the comfortable temperature. . In the air-conditioning ventilation system utilizing the underground temperature of a house according to the present invention, heat is stored in the underfloor by discharging warm air from the living space to the underfloor space, and the underfloor space temperature due to the heat stored in the underfloor. Since the increase of the living space temperature is repeated cyclically, it is possible to realize a stable and comfortable indoor environment in winter with much less energy consumption than conventional heating of the living room.
