DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
It is a screen that can independently perform air conditioning and heating around a person's desk. It uses a thermoelectric element with a Peltier effect as a heat source, can be used only by connecting to a power supply, and can be cooled and opened and closed by opening and closing a switching damper The present invention relates to an air-conditioning partition for desks which can be used for both purposes.

2. Description of the Related Art It has long been practiced to cool and heat an entire office or the like, but in most cases, large or small air-conditioning systems in which cool air or warm air blows out from a specific location on the ceiling of a room or is installed on the floor. Because the air was blown in a certain direction from the machine, the temperature and the flow of air in the room were biased. Therefore, it was not always possible to provide a comfortable environment for all persons due to the position of each person's desk and adaptability to heating and cooling. Also, after a certain time in the evening, the cooling and heating of the office and other facilities was stopped, so the cooling and heating was completely lost during overtime. In recent years, to eliminate such problems,
Panels have been proposed to cool and heat each person's work, but there is a risk that water pipes may be required to cause water leakage, or that only cooling or heating functions are useful only in certain seasons. was there.

[0017]

As described in detail above, the air-conditioning partition for desk-side installation according to the present invention utilizes a thermoelectric element having a Peltier effect as a heat source, and divides a cavity in the partition into three vertically by a picture wall.
It is divided into a heating duct and a cooling duct by a partition plate divided into two in the thickness direction and divided into two sections in the thickness direction. Despite the fact that it has excellent cooling and heating capacity, it has only two movable dampers, so its structure is simple and less susceptible to failure, and it is also used as a power supply for the thermoelectric element with a Peltier effect used as a heat source. The use of a DC power supply makes it possible to use a solar cell, thereby reducing power consumption, and has the effect of keeping the work safe and clean.

When the two changeover dampers are used for either cooling or heating, the operation / changeover switch switches the temperature of the heat passing through the heating duct of the second central passage. If the structure is such that the flow path of the wind and the flow path of the cool air passing through the cooling duct of the flow path in the second central portion are simultaneously switched, the operation is easy, and the hot air discharge port, the upper suction port, and the lower suction port are provided. If filters are installed at the outlet, the cool air outlet, and the cooling air outlet, respectively, it is effective in purifying the air in the environment. The industrial utility value of the desk-side cooling and heating screen according to the present invention having such various effects is very large.
