Detailed Description

Example (b):

reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout, and wherein like reference numerals and letters refer to like items in the following figures, and wherein, once an item is defined in a figure, it need not be further defined and explained in subsequent figures, and wherein the various components that are not explicitly described can be implemented using conventional techniques.

The structure of the square heat recovery core body of the present embodiment is as shown in fig. 2 and fig. 3, and a cage body is composed of an upper square end cover 5, a lower square end cover 5 and four upright post frames 6, and the core body 1 with a square section is embedded and installed in the cage body. The periphery of the end cover 5 is provided with an edge which is formed by bending. As shown in fig. 4, the column frame 6 has a long bar-like structure having an L-shaped cross section, and has an attachment portion formed by bending at an end portion thereof, and the attachment portion is fixedly connected to four corners of the end cover 5 by rivets 8. A handle 7 is mounted on the end cap 5 on one side.

During manufacturing, the upright post frame and the end cover can be punched and bent to be formed by aluminum-plated zinc plates with the thickness of 1mm, after the partition plates and the wavy plates of the core are stacked in the mutually crossed sequence, the upright post frame and the end cover are installed outside the core and are riveted by rivets, screws or welding modes are adopted, four corners of the end cover are fixedly connected with the upright post frame to form an integral square heat recovery core module, four guide rails for fixing the heat recovery core module are arranged in the air duct type fresh air ventilator, the four guide rails correspond to the four upright post frames one by one, and the whole square heat recovery core module is installed into the air duct type fresh air ventilator along the guide rails.

When the air conditioner is used, indoor exhaust air and fresh air respectively flow through the square heat recovery core body in an orthogonal mode, temperature difference and steam partial pressure difference exist in air flows on two sides of the partition plate, and heat and mass transfer phenomena are generated when the two air flows pass through the partition plate, so that a total heat exchange process is caused. When the air conditioner runs in summer, the fresh air obtains cold energy from air exhaust of the air conditioner, so that the temperature is reduced, and meanwhile, the fresh air is dried by air of the air conditioner, so that the moisture content of the fresh air is reduced; when the air conditioner runs in winter, the fresh air is exhausted from the air conditioning room to obtain heat, and the temperature is increased. The energy of the fresh air is recovered from the air exhaust of the air conditioner through the total heat exchange process of the heat exchange core body.
