Problems solved by technology

Although it is currently the best technical solution in terms of cost and economy, its structure is still complicated and its failure rate is relatively high because of the addition of an air distribution mechanism that continuously switches air. In addition, one of its two channels Working under positive pressure, the heat exchange material is placed at the air outlet of the centrifugal fan, and the high-speed airflow directly blows the heat exchange material, resulting in a large loss of pressure and kinetic energy, and it is difficult to balance the air volume of the two channels, and the fresh air outlet and the exhaust air outlet are different. Only half of the channels are opened alternately, and the wind resistance is relatively large, so the air volume and heat transfer efficiency of this solution are also limited to a certain extent.

Embodiment 1

[0035] Embodiment 1 of the present invention is as Figure 1-5 , shown in 10, this example is a kind of basic structure is the pendulum type purifying energy-saving ventilator of single-layer heat exchange core, hangs on the wall and uses, and it comprises the heat exchanger that comprises casing 10, places in the casing 20 and fan device 40; casing 10 is box-shaped, and indoor air return port 15h, air supply port 15s, fresh air port 15x and air exhaust port 15p communicating with the outdoor are arranged on the box wall. The air return port is set at the bottom of the casing, the air supply port is set at the upper part of the front of the casing, the fresh air outlet 15x and the exhaust port 15p are set at the back of the casing, and share a circular or rectangular air duct extending to the outside through the wall hole, such as Figure 10 shown.

[0036] The inner cavity of the casing is divided into a fan chamber 13 and a heat exchange chamber 14 by a transverse partition 1...

Embodiment 2

[0047] Embodiment 2 of the present invention is as image 3 , 6 -10 shown.

[0048] This example is an optimized structure. There are double-layer heat exchange cores in each sub-cavity of the heat exchange chamber, that is, there are four heat exchange cores 21 in the heat exchange chamber 14. The main structure is basically the same as that of Example 1. The main points are the number and arrangement of the heat exchange cores, the driving mechanism, the air duct of the air outlet in the machine, etc.

[0049] The upper wall of the heat exchange chamber 14, that is, the transverse partition 11, has a middle air supply hole 143a, a front row of air holes 148, and a rear row of air holes 145, and the middle air supply hole 143a and the rear row of air holes 145 are connected with the fresh air fan respectively. 41 is directly communicated with the air inlet of the exhaust fan 42, and the front air hole 148 is communicated with the air inlet of the exhaust fan 42 through the ...

Abstract

A swing-core air exchanger, comprising a casing (10), a draught fan (40), and a heat exchanger (20); the heat exchanger (20) has a frame-type heat exchanger core (21) made of fiber material; the heat exchanger core (21) is disposed in a heat exchanger cavity (14), and intermittently swings to switch airflow in the air flue of the air exchanger, such that fresh air and exhaust air alternately pass through heat exchanging material in opposite directions to conduct heat exchange, thus exchanging indoor and outdoor air, and recycling exhaust energy.

Description

Technical field: [0001] The invention relates to an energy-saving indoor air purification device, in particular to a purifying energy-saving ventilator for indoor and outdoor ventilation, recovery of exhaust energy and purification of fresh air. Background technique: [0002] Energy crisis and environmental pollution are the two biggest threats facing all mankind. Indoor ventilation is the most important measure to eliminate indoor air pollution, and recycling air-conditioning energy taken away by ventilation is the only means to ensure economical ventilation. . Energy recovery ventilators have been around since the 1970s. It is commonly known as fresh air ventilator in the industry. For more than 40 years, this product has attracted widespread attention. Its key technology is the heat exchanger. In order to obtain higher heat recovery rate and lower cost, several different technical solutions have appeared in the world. [0003] The first to enter the market is the plate...
