Description

   The present invention is an energy-saving building with high thermal insulation, high airtightness and high sound insulation, and fresh air, oxygen uptake and dirty air, oxygen in the building while exchanging heat in the outside air, especially in the cold winter or hot summer season It is related with the device which discharges simultaneously.

The higher the heat insulation and airtightness of the building, the higher the energy saving effect, but the space between the outside and the space will decrease, so the oxygen in the room will decrease over time. Since humans and living organisms cannot live without oxygen, fresh oxygen such as outdoors, outdoors, and outside air must be taken into the room. If the outside air and outdoors are cold or hot, the room temperature is lowered or raised.

If outside air is put into the room, indoor and indoor air will be expelled. If the air in the room is taken outside, the outdoor air enters the room. When heating, indoor heat discharged indoors, indoor air heat is applied to indoor outdoor air supply or when cooling, heat is exhausted from the outdoor air to reduce indoor temperature changes and energy can be saved. In view of this, various heat exchangers have been devised and marketed that deliver heat from the air supply and exhaust between indoor and outdoor.

There are two types of heat exchangers: total heat and sensible heat. In both types, heat or moisture cannot be sufficiently transferred to the other side unless the gas and air on both sides of the interface are in contact for a certain period of time. Slow down to increase contact area and equipment. If the device becomes large, the installation location is limited, and if it is rotated, a large amount of power is required. In order to allow moisture to pass therethrough, a small through hole must be provided, and dust and dirt are likely to be clogged. Therefore, it must be periodically cleaned or replaced. In the case of sensible heat, since only heat is transmitted, there is an advantage that toxic gas etc. is not mixed, but in order to improve thermal conductivity, the interface film must be made as thin as possible, mechanical strength is weak, and maintenance is difficult turn into.
Patent Publication 2007-315649

The problems to be solved are that the flow velocity is slow, the contact area and the apparatus are large, the mechanical strength of the membrane is weak, clogging occurs, the structure is complicated, and maintenance and maintenance are difficult.

This device does not move or transmit heat between gases by heat conduction, but subdivides the gases and mixes them uniformly. It is not necessary to transfer heat by heat conduction. Of course, if the material is finely divided and mixed, the contact area increases, and heat is easily transferred in part due to heat conduction. Put fresh air containing oxygen from the outside and outdoor suction ports and dirty air such as carbon dioxide with reduced oxygen content inside and from the indoor suction ports into one end of a cylindrical container sealed at both ends. The blower installed in the container was divided into the back and front sides of the board (mixed feather) installed in the container, with the side surfaces closely attached to the container, and the flow was split on the back and front sides. Twist the plate to the right or left so that it can be mixed with the next plate, and then divide it into the back of the next plate and the front and back sides one after another, subdivide, mix uniformly, and stir Like that. You may change the direction of twisting on the way.
Some are heat-conducted on the way and others are finely mixed. A sufficiently subdivided and mixed gas mixture can feel a uniform temperature. The uniformly mixed gas is discharged indoors and outdoors from an indoor outlet and an outdoor outlet installed at the other end of the cylindrical container. In addition to mixed feathers, anything that can be mixed is acceptable. For example, mixing and stirring may be performed only with a blower. There are no disturbing mixed feathers, and the structure is simple, easy to manufacture, and inexpensive. One or a plurality of plate-like or block-like obstacles may be placed. In order to increase the stirring rate by increasing the centrifugal force and the stroke, the cylindrical container may be bent once or a plurality of times, bent spirally, or spirally while twisting. In short, any method may be used as long as the mixed exhaust gas is obtained. There are several types of blowers such as centrifugal, axial flow, diagonal flow, and cross flow types. The outdoor suction port and the indoor suction port are placed on the suction side of the blower, and the outdoor and indoor discharge ports are placed on the discharge side. The blower may be installed in an outdoor suction port, an indoor suction port, an indoor discharge port, or an outdoor discharge port in addition to the inside of the container so that a mixed airflow can be generated.
Since some of the outside air taken in from the outdoor suction port is returned to the outside, it is not possible to use all the oxygen and active ingredients in the outside air, but in the winter, some warm fresh air and oxygen can be taken in indoors. I can do it. In summer, you can get some chilled air and oxygen indoors. The indoor air can be exhausted outdoors, and a part of carbon dioxide can be discharged. If an air conditioner such as a heat supply heater, a heat absorption air conditioner, an ion generator, a humidifier or the like is installed at an indoor outlet to the room or in the duct, the room can be efficiently distributed. Install a filter to remove dust, harmful substances, etc. in the outdoor suction port, indoor exhaust port or indoor suction port, outdoor exhaust port or their ducts, etc. in order to obtain clean air indoors or not spread pollution outdoors. Also good. The cross-sectional shape of the outdoor suction port, indoor discharge port, indoor suction port, outdoor discharge port, duct, and main body container may be any shape as long as gas can circulate, whether circular or rectangular, but the fan part in the main body container has a circular shape. desirable. Although this apparatus has been described with two gases, indoor and outdoor, three or more gases may be put into one end of a cylindrical container, mixed, and discharged from two or more places from the other end of the container. In addition to being installed horizontally, the apparatus may be installed vertically or obliquely according to the shape and convenience of the room.

Since this device mixes gas, there is no limit on the maximum flow velocity and wind pressure. When using a mixed feather plate that is easier to mix evenly and easily, it can be thick and strong enough to withstand wind pressure because it is statically and firmly fixed and does not have the role of heat conduction or moisture permeation. . Forcible, reliable circulation, intake / exhaust by fan force, and the flow speed and flow rate can be adjusted by changing the fan speed and fan blade pitch. This device has a fast flow rate and a thin outer diameter that can be made inconspicuous, can be bent, and can be installed in narrow spaces. The mixing ratio can be adjusted by installing a damper for adjusting the flow rate in the outdoor suction port, the indoor suction port, or the ducts thereof. The distribution of the mixed gas may be adjusted by installing a damper in the outdoor outlet, the indoor outlet, or the duct thereof. Even if the temperature difference between outdoor and indoor is small, it has ventilation function. You may adjust with the flow resistance and windage loss by the cross-sectional area or length ratio of an outdoor suction port, an indoor suction port, an outdoor discharge port, an indoor discharge port, or those ducts. If only the outdoor suction port, the indoor discharge port or their ducts are closed with a damper, it will be used exclusively for discharge. If the indoor suction port, outdoor discharge port or their ducts are closed with a damper or the like, it is dedicated to intake. By connecting a pipe from an arbitrary position in the room to the indoor air supply / exhaust port of this device, air can be circulated, exchanged and ventilated locally. If the through hole is set over the entire length or part of the pipe, the air can be exchanged in whole or in part. By connecting pipes from the outside to the outdoor air supply / exhaust port of the device, the device can be placed at any position in the room. If a driving source such as a motor for driving a fan is placed around the center of the inside of the container, the sound is insulated by the outer skin of the container and the noise is low. If the container, the suction / discharge port or their duct is made of a sound absorbing material, or if a sound absorbing material is affixed to the inside, it becomes more quiet. Heat from the fan drive source can be used for heating. In the case of cooling, a drive source may be installed outside the container so as not to raise the temperature of the mixed gas. Use a belt, gears, etc. to convey power to the fan. The entire container may be installed indoors or outdoors or in the middle. This container is communicated with indoors or outdoors via ducts and pipes. When the entire container is installed outdoors, it is desirable to make or cover the main body, duct, and pipe with a heat insulating material. The amount of natural ventilation inflow that is safe even if the fan stops between outdoor suction ports, indoor suction ports, outdoor discharge ports, indoor discharge ports, or between their ducts or between containers. If the size is larger than the thickness, even if the fan stops, the air is replaced by natural convection and it is safe. Except for the suction and discharge ports of the partition walls between the outdoors and indoors, or through holes in those ducts, it can be made into a completely sealed ultra-highly airtight and ultrahighly insulated building that is more than conventional. You may bend an inlet / outlet or those ducts so that a direct sound may not enter, or install a sound insulation board in the front of an inlet / outlet. It can be made into a very high sound insulation building. In the case of a sound insulation board installed at the outdoor air intake / exhaust port, the effects of strong outdoor winds can be reduced, and rain and birds can be prevented from entering and peeping. If installed in a building with high sound insulation performance, it can be made into a building with even higher sound insulation, and does not leak sound to the outside, so it does not disturb neighbors and neighbors, and is not susceptible to noise from outside. If you install a filter that filters out harmful substances such as dust, pollen and insects at the outdoor suction port, indoor suction port, outdoor discharge port or indoor discharge port, you can spend a healthy time. I am thankful for hay fever patients. Simultaneously with heat exchange, oxygen and other air components are taken in, so the room can be kept in a natural environment. The sensor can detect the temperature difference between indoors and outdoors, or the concentration of harmful gases such as indoor oxygen concentration or carbon dioxide, and the fan is automatically turned on and off, or if the fan air flow rate is adjusted according to the concentration, the setting time will be further reduced. If the above toxic gas concentration is detected, the oxygen or air cylinder is opened and released indoors, or one or more dampers of a size that obtains a safe inflowing air volume with a spring is separated with a spring. It is still safer to excite the lock pin that was holding it open and move it, such as turning a damper with a motor, and forcibly opening it with compressed gas, explosive explosive force, etc. Simple structure, low cost, easy maintenance, long life, and easy operation, it is easy to install at home, office, factory, etc.
Further, the gas may be replaced with a liquid such as water, and a plurality of liquids can be replaced and heat exchange can be performed.

Inexpensive, general-purpose parts, minimum number of parts, simple and easy installation and operation.
