Description

[Detailed description of the invention] Industrial application field This invention relates to a roof structure that is installed above the roof structure to remove snow when thermal equipment for air conditioning equipment is installed on the roof of a region with heavy snowfall. This invention relates to a snow protection roof for a refrigerator (hereinafter referred to as a chiller) used in a system.

BACKGROUND TECHNOLOGY Chillers installed on the rooftops of buildings, etc. in areas with heavy snowfall are
They are used either by connecting an exhaust duct to the hot air outlet or by constructing a roof with a space above. At this time, the exhaust duct is connected to and stands above the exhaust port, and is curved diagonally downward so that the opening faces downward toward rain and snow. When constructing a roof, it is generally sufficient to use a flat plate, which is large enough to cover the entire chiller and is supported upwards by four pillars.In consideration of the snow load, a folded plate structure or large wave slate roof is used. It was said to have a good roof.

Problems that the invention aims to solve The above-mentioned measures for dealing with snowfall in conventional chillers are mainly for functional solutions, and are not aesthetically pleasing for exposed ducts or simple roofs in conspicuous locations such as rooftops. do not have. Furthermore, a flat roof is inconvenient for removing snow when it accumulates, and even if the roof is formed into a mountain shape, hot air will accumulate above the chiller. A more serious defect is that the upward exhaust air from the chiller hits the underside of the roof or the hot air mass under the roof, forming a downward flow, which forms a short-circuit flow toward the cold air intake of the chiller. For this reason, it is necessary to have a large space above the chiller on the roof, and depending on the capacity of the equipment, it is necessary to secure a height of 1.2 m or more, and it is necessary to secure a height of 1.2 m or more above the chiller. It was necessary to strengthen the roof structure.

Means for Solving the Problems The purpose of the present invention is to eliminate the defects of the prior art as described above, and its gist is to construct a roof body by providing a ceiling section on the lower surface of the roof above the chiller, This ceiling part is formed to have a downwardly convex shape, and is characterized by keeping the height above the center of the chiller's exhaust port at the lowest level, and forming an ascending slope from there to the eaves of the roof. As a result, hot air from the exhaust air rises from the exhaust port, naturally moves toward the outer periphery along the ceiling slope, and is released into the atmosphere from the eaves.

Embodiments The present invention will be explained based on drawings of embodiments embodying the principle of the present invention.

In FIG. 1, reference numeral 1 denotes a chiller installed on a base 2, which is one of the main components of an air conditioning system that uses an air-cooled heat pump. Chiller 1
is housed in an outer casing 11, and has an exhaust port 12 at the center of the upper surface of the casing, and two intake ports 13 on opposite sides of the side wall.The intake port 13 is provided with a hood that opens downward; There is an exhaust fan 14 above.
(Fig. 2) is built-in.

Next, in addition to FIG. 2, reference numeral 3 denotes an upper roof body, which in this example is supported upwardly so as to cover the entire chiller 1 by four pillars 4 erected from the upper surface of the casing 11. The roof 31 can be made of any material such as iron plate roofing, small wave slate roofing, or folded steel plate roofing. The roof 31 is provided with a ridge 32 and formed into a gable shape, and the roof structure is formed using four circumferential beams, girders 33, and ridge members 34.

Next, reference numeral 5 denotes a ceiling section provided below the roof 31, on which a ceiling board 52 is stretched using the frame 33 around the four circumferences of the roof body 3 and an appropriate base material 51. use. Here, the ceiling part 5 forms a part of the roof body 3 and is the most characteristic feature of the present invention, and is formed into a shallow V-shape in cross section with the center line 53 parallel to the ridge 32 as the apex. This ceiling surface has a central ridgeline 53 at the lowest point and slopes upward toward the eaves, forming an example of a convex shape that extends downward as a whole. Since a quadrilateral is formed between the gable side end of the ceiling part 5 and the roof 31, a gable wall 35 is provided there. Therefore, it is preferable that the slopes of the roof surface and the ceiling surface be the same, and that the gable surface (also the cross section between the roof and ceiling) be diamond-shaped.

When constructing this roof body 3, the direction of the ridge 32 is aligned with the direction of the air intake ports 13, 13 of the chiller 1, and the outward slope of the ceiling portion 5 is aligned with the side surface where there is no air intake port. Let's face it.

Other forms can be adopted for forming the ceiling portion 5. That is, when forming a downwardly convex surface,
Its shape is a quadrangular pyramid, its apex 53 is positioned above the center of the exhaust port 12 of the chiller 1, and its slopes are directed toward the beams and girders 33 on four sides. Therefore, the gable wall 35 of the roof body 3 becomes a normal triangular gable. Also,
When the ceiling part 5 is shaped like this, the shape of the roof 31 can also be made into a hipped shape,
It is also aesthetically pleasing.

The ceiling surface is not necessarily flat and may be curved hydrodynamically, but this will reduce economic efficiency and workability when considering the formation of the base.

Operation The operation of the present invention having the above-mentioned configuration will be explained based on the operation of the chiller.

When the chiller 1 is operated, heat exchange is performed internally by a heat pump system, cold air is taken in through the intake port 13, and hot exhaust is discharged from the exhaust port 12 by the exhaust fan 14. This heat exhaust becomes an airflow that is divided into two parts by the center ridgeline 53 of the ceiling part 5, flows along the lower slope of the ceiling plate 52 as shown by the arrow, and is radiated into the atmosphere from the eaves. This flow draws a clear flow line due to the natural rise of the hot air in addition to the drive of the exhaust fan 14, and is not subject to any obstruction and there is no risk of short-circuit flow to the intake port 13. Therefore, the spatial height H between the top surface of the chiller 1 and the eaves of the roof body 3 can be selected to be about 0.6 m, compared to 1.2 m in the prior art.

This exhaust flow also heats the ceiling surface, raising the temperature of the air within the ceiling vent. Therefore, the chevron-shaped roof surface is not only convenient for removing snow, but also promotes melting of snow on the roof.

The aesthetic disadvantage of adding a roof to the rooftop installation of the chiller and protruding high is also eliminated by reducing the height, and furthermore, the form creates an aesthetic appearance.

Thermal equipment for air conditioning equipment is not limited to chillers, but a similar roof body can be used for rooftop ventilation towers as well.

Effects of the invention The snow protection roof of the invention is constructed as described above,
Therefore, all the problems of the prior art can be solved and the intended purpose can be achieved.

Here are some of the benefits that can be achieved: (1) It not only avoids the short circuit flow (short circuit) that occurs between the chiller and the roof, but also allows the exhaust flow to be dissipated smoothly.

(2) The height of the space required between the chiller and the roof body can be reduced by approximately half, making it possible to reduce the weight of the structure.

(3) The overall external shape of the roof body has been improved, giving it a functional streamlined beauty, and the diamond-shaped end wall attracts the eye and presents a unique aesthetic appearance.

(4) Not only will it be easier to remove snow from both sides of the slope and height, but natural snow melting can be expected from the exhaust heat.

The present invention greatly contributes to the conventional function-oriented air conditioning equipment system.

This idea can be applied not only to chillers as thermal equipment for air conditioning equipment, but also to open-type heat exhaust systems.
