Abstract

PURPOSE:To simplify the structure, by separating an exhausing air path and an inlet air path by a full heat exchanger having a blower function in an air-tight manner, and providing a blower function for exhausting air and inlet air. CONSTITUTION:An inside air exhausting path (a), which exhausts the air in a room to the outside of the room, an outside air feeding path (b), which feeds the air outside the room to the inside of the room, and grooves, which extend in the radial direction from the central axis of rotation are provided on an inner surface. For example an impeller 20 of wave shaped partitioning plate comprising a material having moisture permeability such as kraft paper is provided. The inside-air exhausting flow and the outside-air feeding flow are yielded from both sides of the impeller 20 by the rotation of the impeller 20 with a rotary axis as a center. A full heat exchanger 11 having a blower function, which performs full heat exchange between both air flows, is provided. The full heat exchanger 11 separates the air paths (a) and (b) by itself in an air tight manner. The grooves A and B on both surfaces of said impeller 20 form parts of both air paths (a) and (b).

Description

[Detailed description of the invention] Industrial applications The present invention relates to an air conditioning ventilation system having a total heat exchange function.

Structure of the conventional example and its problems Conventional ventilation equipment generally has the structure shown in Fig. 1, in which a motor 2 is fixed to an outer frame 1 provided by cutting through a wall. The configuration was such that dirty air inside the room was sucked in by the blowing action of an axial fan 3 rotated by the fan 3 and exhausted to the outside. In the figure, the arrow indicates the air flow n.

In the case of a ventilation system with this type of structure, it simply sends indoor air outside, so it does not actively take in fresh air into the room, and it does not cool indoor air. As the heat is discharged, the heat held in the indoor air is also discharged, causing a change in the indoor temperature state.

In other words, in winter, the indoor temperature drops as the warm air inside the room is released outside, and especially during heating, the heating effect is significantly reduced because the heated indoor air is exhausted outside. , the thermal loss is large. In addition, in the summer, it causes a great influence on the cooling effect, which is a very serious problem in practical use.

For this reason, conventional ventilation devices are generally used for local ventilation, and are often installed only near cooking utensils in the kitchen or in washrooms, and can only be used for one short poem. However, there were few cases where ventilation equipment was used for purposes such as continuous ventilation of the air in an entire room.For this reason, in recent years, ventilation equipment has been equipped with a built-in heat exchanger.
A heat exchange type ventilation system has been proposed that recovers the heat retained in dirty air discharged from a room and returns it to the room. However, in such a heat exchange type ventilation system, the built-in heat exchanger is expensive and has a complicated structure. OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned conventional drawbacks and provides a compact and inexpensive air conditioning and ventilation system.

Structure of the Invention The present invention provides an indoor air exhaust duct for discharging indoor air to the outside, an outdoor air supply duct for supplying outdoor air into the room, and grooves extending radially from the rotation center shaft on the inner surface. equipped with wavy partition blades made of a moisture permeable material,
A total heat exchanger with a blower function that generates the indoor air exhaust flow and outdoor air supply flow on both sides of the blade by rotating the blade around the rotation axis, and performs total heat exchange between the two air flows. , the total heat exchanger itself airtightly separates the airflow path, and the grooves on both sides of the blade form a part of the airflow path. , can contribute to downsizing and cost reduction of equipment.

Reference numerals 17 and 18 denote an exhaust air casing and an intake air casing, which form the entire passage for the air flow generated by the total heat exchanger 11 with a blower function.

Next, details of the total heat exchanger 11 with an air blowing function will be explained based on FIGS. 3 to 5.

It has grooves A, . . . B extending radially as shown in FIG. 21 is a boss provided on the inner main plate 19 for fixing the total heat exchanger 11 with an air blowing function to the motor shaft. Dimensions 22 and 23 are an inner support plate and an outer support plate that support the blade 20 made of a corrugated thin plate.
゜23 supports the blade 2o and at the same time airtightly controls the two air flows generated on both sides of the total heat exchanger 11 with a blower function.
It also serves as a blind plate to separate the parts. In addition,
In FIG. 3, in order to make its presence clear, only the outer support plate 23 located at the front in the figure is shown with diagonal lines.

As shown in FIG. 5, the above-mentioned air flows a' and b' are formed by using grooves A and B on both sides of the blade 20 as ventilation passages, which are adjacent to each other in the thickness direction of the blade 20, and there is a temperature between them. If there is a difference in humidity and humidity, total heat exchange can be performed through the highly moisture-permeable blades 20.In the above configuration, when the motor 10 is powered on, the total heat exchanger with the air blowing function is Exchanger 11
rotates, and indoor dirty air is sucked in through the indoor air intake port 6.

At the same time, on the opposite side of the central partition plate 12, outdoor air is sucked in, and the airflow on both sides is caused by the blades 2 shown in FIG.
It is guided to grooves A and B on both sides of 0.

After the total heat is exchanged in the total heat exchanger 11 with ventilation function, the dirty indoor air is exhausted to the outside through the exhaust air path indicated by the solid arrow a in Fig. Air is sent into the room through the intake air path indicated by the dashed arrow.

In the ventilation function as described in Section 2, the total heat exchanger with ventilation function 11 shares the total heat exchange function and the ventilation function. Therefore, total heat exchange takes place (7tpA) on both sides of the blade 20.
, B part generates a high-speed air flow, and the growth of a temperature and concentration boundary layer that inhibits the heat transfer effect spreads, resulting in extremely efficient heat exchange.

The structure is much simpler than that of a replacement type ventilation device, and the ventilation device can be provided at a low cost. Furthermore, compared to conventional general ventilation equipment, its functionality has been greatly improved, and it can ventilate the room without changing the temperature or humidity (
Not only can it be used to ventilate the entire room C, but it can also be used continuously, and because it does not change the temperature and humidity conditions inside the room, there is less heat loss compared to conventional methods, and it can be used for heating in winter. It has great effects, such as further increasing the cooling effect in the summer and saving energy.
