Description

[Detailed description of the invention] Industrial applications This invention relates to a heating/cooling device.

3. Prior Art Conventionally, (1) a heater using a radiant panel and a heat pump type air conditioner using electric power, and (2) a heating/cooling device using hot air and cold air are both well known.

Problems to be Solved by the Invention However, in the case of item (1), the heater and the air conditioner are manufactured separately, and the installation work is done separately. There is also the problem that it takes up a large amount of space and can only be installed in limited places, and in cases like (2),
When heating, it makes a lot of noise, making it difficult to use while sleeping, and when indoors, warm air gathers in the upper part, making it difficult to heat the lower part.

Therefore, the purpose of this invention is to solve the above-mentioned problems of conventional heating/cooling devices, to achieve heating and cooling by an integrated upper and lower unit, to make the whole compact and easy to install. Another object of the present invention is to provide a heating/cooling device that can uniformly distribute warm air indoors during heating and further reduce noise.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention includes a heating radiant panel on the lower side and a cooling panel having an air passage on the upper side in the enclosure, on the rear side thereof. They are connected to each other to form a hot air passage and a cold air passage, and the openings at the top of the hot air passage and at the bottom of the cold air passage can be selectively opened and closed by switching blades, and the heating radiant panel and the cooling panel are connected to each other. A hot/cold air passage communicating with the opening and having a hot/cold air outlet at the tip is provided in the middle,
An air supply fan is provided in this hot/cold air passageway to draw in outside air and blow it out from a hot/cold air outlet.

Function: In the heating/cooling device of the present invention as described above, during heating, the heating medium is circulated through the heating radiant panel, the air supply fan is operated, and the switching blade is connected to the opening at the top of the hot air passage. The fan is operated so that it communicates with the radiant panel, and the fan is heated using both the radiant heat from the front of the radiant panel and the warm air ejected from the hot/cold air outlet. The system performs heating in a quiet environment with no air flow, and therefore a clean environment.In addition, during cooling, the cooling medium is circulated within the cooling panel, the air supply fan is operated, and the switching blades are switched between the cold air passage and the warm and cold air passage. The cool air is ejected from the warm and cold air outlet to cool the air.

Example The embodiment shown in the drawings will be described.

Reference numeral 1 denotes an enclosure with an open front, and inside the enclosure, there is a heating radiation panel 2 at the bottom, a cooling panel 3 having a cold air passage at the top, and a hot air passage 4 and a cold air passage at the rear thereof. They are arranged in series to form 5.

The openings 6 and 7 in the upper part of the hot air passage 4 and the lower part of the cold air passage 5 are opened by operating the switching lever 19 to open the switching blade 8.
When one side is opened, the other side is closed, and FIG. 1 shows the state where the opening 7 is open.

These openings 6 and 7 are the radiation panel 2 and the cooling panel 3.
An intake fan 9 is provided in this hot and cold air passage 12, and this fan 9 is rotated by a motor 11. Indoor air at the front is sucked from above and below through the cooling panel 3 into the cold air passage 5 or the hot air passage 4 by the operation of the fan 9, and is cooled or warmed and then ejected into the room from the outlet 10.

Such a heating/cooling device is disposed in a recess 25 provided in a wall surface, and a heat medium is circulated through a heat medium supply pipe 13 from a heat source (not shown) to the heating radiation panel 2, and a refrigerant is supplied to the cooling panel 3. A normal cooling member consisting of a cooling fin 15 attached to the refrigerant pipe 14 and the refrigerant pipe 14 is provided.
Refrigerant is circulated through a refrigerant pipe 16 from a refrigerator (not shown). Hot water pipe] 3. In this embodiment, the refrigerant pipe 16 is arranged in a plastic pipe I8 arranged in a pipe storage box 17 provided on the floor.

The back surface of the enclosure 1 is covered with a heat insulating material 20 and fixed to a wall surface with anchor bolts 21. 22 removes the drain from the bottom of the cooling panel 3, the drain pipe, and 23
Reference numeral 24 indicates a control electrical equipment section, and 24 indicates an operation switch.

In the above-mentioned device, when heating is to be performed, the heating radiant panel 2 is turned on by operating the operation switch 24.
While circulating the heat medium inside, the fan 9 is rotated, and the switching blade 8 is rotated counterclockwise from FIG. 1 by operating the switching lever 19 to close the opening 6 and close the opening 7.
Open. As a result, the room temperature is warmed by the radiant heat in the front of the radiant panel 2, and the fan 9
Air heated by flowing through the hot air passage 4 as shown by the solid arrow is ejected from the outlet 10 by the operation of the fan 9, and the room temperature is also heated at the same time by this warm air.

During this heating, when heating for a long time or when heating while sleeping, the fan 9 is stopped to stop blowing out hot air from the outlet lO, thereby reducing the amount of air generated when the hot air flows. Not only is noise prevented, but also environmental deterioration due to the diffusion of indoor dust and the like is prevented by stopping the flow of air.

When attempting to cool the air next time, the refrigerant is circulated through the refrigerant pipes 14 in the cooling panel 3, the fan 9 is rotated, the switching blade 8 is rotated to the first illustrated position, and the opening 6 is rotated.
is opened and the opening 7 is closed. As a result, air that has been cooled by flowing through the cooling panel 3 in the direction of the dotted arrow by the fan 9 is ejected from the air outlet 10 to cool the room.

Effects of the Invention The second invention is as described above, in which the heating radiant panel and the cooling panel are integrally connected vertically via a hot air passage in the middle, and the heating radiant panel and the cooling panel are provided on the rear side of the radiant panel and the cooling panel. The provided passages are selectively opened or closed by switching vanes and communicated alternately with the hot and cold air passages, and in this way, outside air is circulated behind the cooling panel or the radiation panel by the operation of the air fan, and the air is heated. The heated or cooled air is then blown out from the outlet of the hot air passage, so during heating, the heat radiated from the surface of the elbow panel and the hot air passing through the hot air passage heat the entire top and bottom of the room. In addition, when sleeping, heating is performed only by radiant heat, preventing the generation of noise, and keeping the room clean by not dispersing the indoor air. During cooling, the cooling panel sucks in the warm air that accumulates in the upper part of the room, cools it, and then blows it out.
4. It is compact as a whole, making installation work extremely easy, and its short depth means that it does not require a large space for installation.
