Description

[Detailed Description of the Invention] The present invention effectively utilizes indoor exhaust gas and drain discharged from a cooler, which were conventionally treated by a total heat exchanger during indoor cooling, and achieves economical and highly efficient heat exchange. This relates to a good air conditioner.

Usually, as a system for cooling each room in a multi-story building, etc., most systems install a condenser on the roof of a high place, connect this with a pipe to a cooler placed inside each room, and then Heat recovery treatment methods are carried out using a total heat exchanger that can be installed at each location, or by using ducts all at once, but as mentioned above, installing a condenser on the rooftop at a high place impairs the aesthetic appearance of the building. At the same time, there are problems with the risk of collapse due to wind and rain, durability due to sunlight and corrosion, and not to mention noise pollution.In particular, installing a total heat exchanger as a separate unit for each room is problematic. There were various drawbacks such as the installation space required and considerable expense.

In view of these drawbacks, the present invention aims to make the overall shape extremely compact without using the expensive total heat exchanger, and aims to be economical and efficient. A U-shaped ventilation passage is formed with a plate, and a refrigeration cycle such as a condenser, compressor, and blower are arranged in the ventilation passage, and one side of the ventilation passage is connected to the indoor exhaust duct, and the other side is connected to the indoor exhaust duct. An air conditioner characterized in that a ventilation passage is connected to each of the outdoor exhaust ducts, and the drain water from a cooler installed indoors is made to drip into the condenser through a drain recovery pipe. This is what we are trying to provide.

Hereinafter, specific embodiments of the present invention will be explained in detail with reference to the drawings. 1 is a fuselage whose internal center is adjacent to the left and right by a partition plate 2 to form a U-shaped air blower in an intake passage A and an exhaust passage B. A condenser 3 is placed in the intake side passage A, a liquid receiver 4 and a compressor 5 are placed in the lower part of the exhaust side passage B, and a blower 6 and a motor 7 are placed in the upper part.
Each mechanism is arranged respectively.

The intake port 8 of the intake side passage A is connected to an indoor exhaust duct 10 and an intake duct 11 for taking in outside air, respectively, and the exhaust port 9 of the exhaust side passage B is connected to the external exhaust duct 12 side.

Further, the exhaust duct 10 and the intake duct 11
Inside are dampers 13 and 14 for switching intake air amount adjustment.
are provided so that they can be opened and closed freely.

In addition, the installation locations of each device constituting the refrigeration cycle are not limited to the illustrated drawings,
For example, the condenser 3 may be installed in the exhaust passage B, and the compressor 5, blower 6, etc. may be installed in the intake passage A.

Reference numeral 15 is a drain recovery pipe, one end of which is connected to the drain pan of the indoor cooler a, so that the drain is naturally guided and dripped into the condenser 3.

Reference numerals 16 and 17 indicate refrigerant flow pipes for the indoor cooler ae, and a drain pan 18 is located below the body 1.
Set up.

In addition, a front plate 19 with an appropriate design and color is installed at the front of the vessel body 1 so as to be able to be opened and closed to provide a design effect and to allow various operations such as maintenance of the interior of the vessel to be carried out easily. There is.

Incidentally, the condensing unit having the above structure is arranged as a single unit in each room of a multi-story building as shown in the third figure, and each is configured into an air conditioning system connected to the indoor cooler a. Cold air and outside air are introduced into the intake side passage B, which connects the condenser 3, compressor 5, and blower 6.
The refrigeration cycle is exhausted to the outside through an external exhaust duct 12 through an exhaust side passage B while naturally recovering cooling heat.

Meanwhile, fresh air from the outside is being processed by the cooler a on the indoor side without using a total heat exchanger, and the drain from the cooler a is dripped into the condenser 3 through the drain recovery pipe 15. Cooling heat exchange will be performed more effectively.

Although the above embodiment is based on a condensing unit for indoor installation, it is also fully possible to use this structure for outdoor use.

As described above, since the air conditioner according to the present invention has a U-shaped ventilation passage inside the airframe 1, sufficient space is required for arranging various refrigeration cycle devices within the passage, and, This allows the overall shape to be made compact, and allows the indoor cooling air to reliably flow through the U-shaped ventilation passage, allowing efficient heat recovery to be naturally achieved between the flows. Since only unnecessary exhaust gas is discharged outdoors, it is extremely energy-saving and economical. Furthermore, drainage is easy and simple, no insulation is required, and piping is easy.
By using more drains, more effective energy saving effects can be expected.

In particular, in the present invention, as mentioned above, a total heat exchanger is not required at all, and the economical effect is extremely remarkable, and the overall shape can be made compact, so it can be used in narrow spaces such as outdoor walls, corners of warehouses, toilets, etc. It is a beneficial invention that can be easily installed in any location, does not impair the beauty of the building, completely eliminates the fear of corrosion, and has other effects such as durability and low noise.
