Abstract

PURPOSE:To equalize temperature distribution by forcibly moving the cold and hot air and make the energy for the moving of the air minimum by installing on the lower face of a ceiling distribution pipes in a required number with a certain distance among them, the distribution pipes being provided with blow-out nozzles and blowing out cool air or hot air successively and intermittently. CONSTITUTION:The whole or part of cold or hot air from a blow-out opening 3 for cold and hot air is taken into a blower 5 and this cold or hot air is made to blow out intermittently with a certain time interval from distribution pipes 7, 7'... that are arranged on the lower face of the ceiling. In blowing out this cold or hot air by a nozzle 9 which makes the blow-out opening 8 narrow and a blow-out nozzle 11 which forms a Venturi 10 as one body by support rods 15 and 15', the cold or hot air stagnant at the lower face of the ceiling is taken in from the upper and lower ends of the Venturi 10 and blown out as a jet air stream with a speed several times as fast, and after this air temperature regulation in the building is attempted by the convection flow developed by the jet air stream.

Description

[Detailed Description of the Invention] The present invention takes in the cold and hot air from the air conditioners installed inside and outside the building into a blower, and from there, all the distribution pipes are installed with blow-off nozzles placed at appropriate intervals on the lower surface of the ceiling inside the building. By installing several pipes and intermittently blowing out cooling and heating air from the blow-off nozzles of each distribution pipe, the temperature difference between the lower surface of the ceiling inside the building and the range of human working height during cooling and heating can be reduced.
The present invention relates to an in-building temperature control device that effectively utilizes thermal efficiency during heating and cooling.

[Conventional technology]

Conventionally, in various workplaces and offices with equal pressure, air conditioners installed in one corner of the building powerfully blow out cool and warm air until the range of working height for humans reaches a comfortable temperature. After that, it is common to control the airflow while heating and cooling the room.

[Problem that the invention seeks to solve]

However, by only blowing out cool and hot air from the air conditioner installed in one corner of the building, areas near the air conditioner are relatively well heated and cooled, but the air does not circulate in areas further away from the air conditioner. Therefore, in order to maintain a comfortable temperature even in this remote area, the air conditioner must be operated strongly for a considerable period of time, and even in the vicinity of the air conditioner, there is a risk of damage to people's feet, including the underside of the ceiling and the floor. If we compare the temperatures within the working height range, there is a significant temperature difference. For example, during heating in winter, warm air has a low gas density, so even if warm air is blown out from below the heater, it easily accumulates at the bottom of the ceiling and does not fall to the range of human working height. In order to reach a comfortable temperature within this range, high-temperature warm air must be blown out for a considerable period of time to reach a comfortable temperature down to the feet on the floor.On the other hand, the high-temperature warm air stays in a thick layer under the ceiling, and the thermal efficiency of the warm air is effectively used. This is especially true in workplaces with higher ceilings than offices.

[Means to solve the problem]

As mentioned above, the present invention was created in order to make efficient and effective use of the thermal efficiency during heating and cooling, and its purpose is to forcibly move the cooled and heated air inside the building during heating and cooling. It was developed to equalize the indoor air temperature and to minimize the energy required to move this cool and warm air.The cool and warm air blown out from the air conditioner is blown out by blowing nozzles placed at appropriate intervals on the underside of the ceiling. The required number of installed distribution pipes are installed at regular intervals, and the cold and hot air blown out from the air conditioner is instantaneously and intermittently blown out from the blow-off nozzle of each distribution pipe using a blower. This system takes in the cool and warm air that is drawn into the blower from the air conditioner and heater, as well as the cool and warm air that has accumulated in a thick layer on the underside of the ceiling, and blows it down, forcing the cool and warm air inside the building to move like convection. This makes the temperature of the air inside the building uniform and the thermal efficiency of the heated and cooled air is effectively utilized with high efficiency.

[For production]

According to the present invention, the distribution pipes installed at regular intervals under the ceiling are designed to take in all or part of the cooled air from the air conditioner into the blower, and on the other hand, the distribution pipes are installed at appropriate intervals under the ceiling. The blow-off nozzle to be installed is a nozzle with a narrow blow-out opening at the bottom end attached to the distribution pipe, and a Venturi with a wide opening at the top end connected integrally at a distance from the bottom end of this nozzle. The narrow nozzle instantly and powerfully blows out the cold and warm air, which removes the cold and warm air that has accumulated around the nozzle under the ceiling.
The nozzle is narrower by drawing in the air from the upper and lower ends of the Venturi to increase the ejected airflow and blow it out downward, creating a convection phenomenon around this blow-out nozzle and effectively utilizing the cooling and heating air without wasting it. The amount of ejection at the lower end is increased by several times using a venturi to minimize the movement energy of cooled and warmed air, thereby making highly efficient use of such thermal efficiency.
