Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conditioner incorporating a natural evaporation type humidifier.

[Prior art]

From the perspective of energy conservation, modern living spaces are becoming more insulated and airtight, and increasingly sophisticated air conditioning is required. Air conditioning elements include temperature control, humidity control, and control of harmful air components. Regarding temperature control, various heating and cooling methods have been put into practical use, and the situation is satisfactory. However, there is still nothing completely satisfactory in terms of humidity control and control of harmful air components.

Regarding humidifiers, there are natural evaporation type, electric heating type, water spray type, and ultrasonic type, but natural evaporation type has low humidifying capacity, electric heating type has high running cost, and water spray type has low humidification efficiency. Become lower and larger. Furthermore, the ultrasonic method has drawbacks such as high initial cost and short life.

Therefore, we have repeatedly considered ways to greatly improve the humidification capacity of natural evaporation type humidifiers, which have low initial costs and running costs and are the most versatile. In the natural evaporation method, in order to maximize the area for water evaporation, a vat-shaped container with a large opening is used, and the lower end of a woven hydrophilic fiber is immersed in water to cover the surface of the water by capillary force. Efforts are being made to increase it. If the water were to be sliced into several thicknesses and arranged in multiple layers vertically, the area for water evaporation could be greatly increased.

As a result of repeated research on a method for vertically holding sliced water with a thickness of several inches thick, we found that the hollow part of a hollow porous member with an internal thickness of several micrometers is made of porous hydrophobic polymer. It was previously discovered that water can be held in any space by containing the sliced water, and the water can evaporate freely.

In order to commercialize a natural evaporation type humidifier using the above-mentioned sheet of porous hydrophobic polymer material (hereinafter referred to as porous sheet), we prototyped the humidifier shown in Figures 4, 5, and 6. .

In the figure, 1 is a hollow porous member formed into a rectangular shape by overlapping porous sheets 2 and bonding or heat-sealing the ends, and both ends 1a have a water supply port 3 communicating with the hollow part 1b, and a drainage hole. A port 4 is provided. Reference numeral 5 denotes a wavy spacer that is rolled up along with the hollow porous member 1 so as to form a ventilation path between the stacked hollow porous members when the hollow porous member 1 is rolled up. Reference numeral 6 is a core member having a rectangular parallelepiped outer shape, and the hollow porous member 1 and the wavy spacer 5 are wrapped around the core member 6 to form a humidifier T. form nine. Connect this to the water supply port 3 above.
An evaluation test of humidification ability was conducted by sending air between the porous members while supplying water.

[Problem that the invention seeks to solve]

As a result, in order to fix the humidifier to the heat exchanger with plate fins built into the air conditioner, it is necessary to provide a frame for the humidifier 70 frame on the heat exchanger with plate fins! 90 The present invention provides a humidifier that can easily be installed at a desired position on a heat exchanger with plate fins without the need to install a special mounting frame on the heat exchanger. The purpose is to provide a built-in air conditioner.

[Means for solving problems]

In the air conditioner according to the present invention, several hook-shaped fasteners are provided on the frame of the humidifier using a hollow porous member, and the two are hooked onto the steel pipes of the heat exchanger using the fasteners to fix both. It is something.

[Effect]

In this invention, the humidifier can be easily installed in an air conditioner by hooking the hook-shaped fastener attached to the frame of the humidifier onto the steel pipe 6 of the heat exchanger with plate fins.

〔Example〕

This invention will be explained below based on the drawings. FIG. 1 is a cross-sectional view showing one embodiment of the present invention, showing a humidifier T using the hollow porous member 1 described in the conventional example, and a plurality of fins 8a arranged in parallel and penetrating the humidifier T at right angles. FIG. 2 is a diagram showing a combination of a plate-finned heat exchanger 8 made of copper tubes 8b.

FIG. 2 is a perspective view of the humidifier 7. In FIGS. 1 and 2, 9 is a hook-shaped stopper for hooking the copper tube 8bK of the heat exchanger 8 with plate fins, and is fixed to the frame of the humidifier.

Figure 3 shows a diagram of an air conditioner incorporating these components.

In FIG. 3, reference numeral 10 includes a blower 11 that generates air flow for the humidifier 7 and heat exchanger 8 described above, and further includes a filter 12 for removing large particles from the sucked air, and a blowout grill. This is an air conditioner composed of 13.

During heating operation of the air conditioner 10, first a flow of air is generated by the blower 11, and the air is sent from the filter 12 to the heat exchanger 8, where it absorbs heat from the heat source in the pipes of the heat exchanger 8 and the warmed air is passed through the hook. The water flows between the hollow porous members formed by the corrugated spacers 5 of the humidifier 7, which is attached to the heat exchanger with shaped fasteners 9. On the other hand, water supplied from the water supply port to the hollow portion 1b of the hollow porous member 1 becomes water vapor and passes through the porous sheet 2, whereby the air is humidified and exits through the outlet grille 13.

〔Effect of the invention〕.

As described above, the present invention includes attaching a plurality of hook-shaped fasteners 9t to a humidifier 70 frame using a hollow porous member, and attaching the fasteners 9 at right angles to a plurality of fins arranged in parallel. By hooking the humidifier 7 to the steel pipes of the heat exchanger 8 with plate fins, which are made of a plurality of copper pipes 8b passing through the humidifier 8, the humidifier 7 can be easily attached to any position on the heat exchanger 8.
