Description

1295359 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a full-heat-interchange device in which the heat-intersecting device is improved in the indoor air quality and has a full heat exchange function. [Prior Art] In the actual daily life, in order to ensure the indoor air quality, it is often necessary to install an air-conditioning system, such as a meeting place, a large supermarket, an office building, etc., so that the secret room _ The dirty air is discharged outside, and at the same time, the external _ light gas (job) is added to _, turning over the demand of the standard. However, direct replacement of indoor and outdoor air will bring a lot of energy loss. For example, in summer, the energy loss caused by replacing a large amount of fresh air (hot air) with high outdoor temperature in the indoor air conditioner is used. very big. In order to solve the above-mentioned indoor air pollution and energy conservation problems, the total heat exchange device should be increasingly affected by the air, and the whole heat exchange device can achieve the introduction of outdoor fresh air to dilute indoor pollution and eliminate indoor dirty air. Simultaneously performing sensible heat (temperature) and latent heat (humidity) full heat exchange between the convection of the above two airs, and effectively controlling indoor air quality in the air conditioning system, maintaining a healthy and comfortable and energy saving method. The commonly used full heat exchange device mainly has two types of rotary type and alternating current type, wherein the full heat exchange filter element of the parent flow type full heat exchange device is fixed in the casing and is in a fixed state, so it is also called static. Set or fixed full heat exchange unit. The first figure is not the working principle of the static heat exchange device. The full heat exchange filter 1 is a moisture-permeable and non-breathable wet heat switch paper, such as a fiber paper substrate. A wavy plate 4 having a plurality of airflow inlets 3 is further disposed between the plates 2, and the wavy plates 4 are arranged in a staggered arrangement at the indoor side 1 and the outdoor side, so that the all-heat-replacement filter element 1 is not connected to each other. Two indoor and outdoor airflow channels, namely Figure 1295359
The indoor exhaust passage E_E and the outdoor intake passage F_F are not in use, ensuring that the two air flows are not mixed. When the exhaust gas and the intake air are respectively guided by the fan to exchange indoor and outdoor air through the total heat exchange filter 1, respectively, the two air flows are transferred as heat due to the existence of a temperature difference, and at the same time The plate 2 is permeable to water and gas, so that the moisture mass transfer effect can also be achieved, so that the exchange of temperature and humidity between the exhaust gas and the intake air flow can achieve the effect of energy saving and sewage discharge. This heat exchange process, which transfers both energy and humidity, is a full heat exchange. However, in order to exert the advantages of full heat exchange, there are still the following shortcomings and improvements in the design of the total heat exchange device: (1) The heat exchange efficiency needs to be improved. Since the latent heat and the sensible heat exchange are completed by the two-way intersecting passage formed by the partitions by the two air currents of the intake and exhaust, the exchange efficiency is completely determined by the functional paper between the passage partitions, but the function is The paper is mainly characterized by strong hydrophilicity, and the improvement of heat transfer is often impossible to balance. The efficiency of sensible heat exchange still has much room for improvement. - (2) The flow of air entering the wavy plate airflow inlet is not uniform. Because the wind direction blown by the fan and the wind direction entering the small passage in the full heat exchange filter element are often not in a straight line, but at an angle, and entering the end of the flow path formed by the filter element and the casing is a machine facing the main air flow. The shell end plate is subjected to the secondary air flow directly impacting the end plate and the incoming main air flow interaction and steering effect, so that the flow field between them is very chaotic, and most of the air flow entering the filter element only converges on a small part of the wavy air flow inlet. In the above, the uneven air volume distribution between the above-mentioned inlets is very disadvantageous to the overall exchange efficiency. SUMMARY OF THE INVENTION The main object of the present invention is to provide a total heat exchange device for improving indoor air quality, so that the heat exchange efficiency is further improved.
