Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an air conditioner configured to simultaneously draw in outside air and discharge indoor air, and also to exchange heat between the drawn air and the discharged air. It concerns ventilation equipment.

[Conventional technology]

An air conditioning ventilation system is mainly composed of a blower and a heat exchanger, and the conventional one, as disclosed in Japanese Patent Publication No. 50-2950, uses a partition plate to separate two fluids to be heat exchanged. A heat exchanger is used in which the fins are laminated with corrugated plate-shaped fins sandwiching them to form a double row of fluid flow channels. The partition plate is made of a paper material based on Japanese paper that has both heat conductivity and moisture permeability, and the fins are made by processing the same paper material as the partition plate into a corrugated plate and cutting it into a predetermined size and shape. It has been obtained. Then, through this heat exchanger, the discharged air warms or cools the intake air, and also adds or absorbs humidity to bring the temperature and humidity of the intake air closer to the temperature of the output air. So do it.

[Problem that the invention seeks to solve]

In conventional air conditioning ventilation systems that incorporate the heat exchanger described above, it is customary to use a cross-flow type blower, which has a large pressure loss in the heat exchanger and whose wind pressure is not so large, and also has relatively low power consumption and noise. It's a big thing.

Does the present invention solve such problems? The objective is to obtain an air conditioning ventilation system that is compact and can reduce power consumption and noise.

[Means for solving problems]

The air conditioning ventilation system according to the present invention is a heat exchanger in which a plurality of unit members are laminated, each having a plurality of thin hollow bar-shaped spacing members arranged in a row on one side of a heat-conductive flat partition plate. A cross-flow type blower for forming an intake air flow is provided in the intake passage, and a cross-flow type blower for forming an exhaust flow is provided in the exhaust passage.

[Effect]

In this invention, the spacing member in the integrated heat exchanger 1 has a hollow structure and is thin, and the hollow part also serves as a fluid flow path, so the pressure loss is small, a cross-flow type blower can be used, and the consumption It uses less electricity, less noise, and is more compact.

The air cleaning filter is installed to cover the air purification filter, the cross-flow blower for intake is installed in the intake passage QO, and the handle is the exhaust passage (9)? The exhaust cross-flow blower CD is a heat exchanger provided at the intersection of the intake passage αO and the exhaust passage (9), which will be explained with reference to FIG. 2P. This heat exchanger 61! υ is
Between each of the plurality of partition plates (A), there are linear or rod-shaped spacing members P arranged at equal intervals in a certain direction, thereby forming a large number of fluid flow paths. ) are shifted by approximately 90 t for each layer. The partition plate (a) is made of Japanese paper, etc., which has both heat conductivity and moisture permeability, and has a thickness of 0.05 MM or more.
It is a rectangular flat plate of about 0.2# and is a member that partitions two fluids to be heat exchanged. Then, on one side of the heat exchanger (21), spacing members α) obtained by extrusion molding of vinyl chloride or foamed resin are adhered in rows (sometimes integrally molded) at predetermined intervals. A unit member H is configured as a structural unit. The spacing member (c) number of each unit member (c), in the example shown, the outer diameter is 2tnm and the wall thickness is 0.1 to 0.2
It is a vibrator with a wall as thin as a MM. Between the spacing member (to) and the spacing member (to), a fluid flow path (
C), and the hollow portion of the spacing member (to) also serves as a fluid flow path. Note that the spacer member t may be a square tube, a triangular tube, a hexagonal tube, or the like.

Next, the operation of this air conditioning ventilation system will be explained. When this ventilation device is driven, the cross-flow type blower (1) sucks indoor air from the suction port (5) through the filter α force and the fluid flow path (A), and discharges it to the outside from the discharge port (8). In addition, the cross-flow type blower 0O inhales outdoor air (7)
The fluid is sucked in through the filter
It is supplied into the room through the outlet (6). As a result,
The indoor air is ventilated, and in the heat exchanger (c) t, so-called total heat exchange of heat and moisture exchange is performed between the exhaust air flow and the intake air flow, so the ventilation of this equipment is
Therefore, the indoor temperature and humidity do not change significantly. The heat exchanger (c) has a wide fluid flow path (a), and the dynamic pressure does not change to static pressure due to air collision against the end face, so the pressure loss is small. Therefore, even with a cross-flow type blower with relatively low wind pressure, sufficient ventilation can be achieved, reducing both power consumption and operating noise. It is possible to achieve any shape.

〔Effect of the invention〕

As is clear from the above description of the embodiments, the air conditioning ventilation system of the present invention has a box-like structure in which one set of suction ports and one set of discharge ports are provided on each of the indoor side and the outdoor side.
An intake passage and an exhaust passage from the indoor side to the outdoor side are provided so as to intersect with each other with a partition plate between the suction port and the discharge port, and the inside of the intake passage t′- forms an intake flow. A cross-flow type blower WL machine is equipped with a cross-flow type blower that forms an exhaust flow in its exhaust passage, and a thin hollow rod-shaped spacing member is arranged in a row on one side of a flat partition plate having heat conductivity. A cross-flow blower in which a heat exchanger made up of a plurality of bonded unit members is provided at the intersection of the intake passage and the exhaust passage, and the pressure loss of the heat exchanger is small and the wind pressure is relatively low. This makes it possible to create a slender and compact structure as required, and also to reduce power consumption and noise.
