Embodiment 1

[0031] Fig. 1-Fig. 5 is the structural principle diagram of embodiment 1 of the present invention, and Fig. 1 is its vertical A-A step sectional view, Fig. 2, 3 is B-B, C-C sectional view respectively. As shown in the figure, this embodiment is a new type of purification and energy-saving ventilator, which includes a casing 10, a heat exchanger core 20, and a gas distribution mechanism 30; the casing 10 is box-shaped, with an air inlet at each end 14j, 15j and the air outlets 14c, 15c communicate with the outside of the machine, and the inner cavity of the casing is divided into two sub-chambers 11 and 12 by a partition 13; two inner walls of the sub-cavities 11 and 12 respectively have two air outlets 111 . 15c is connected, as shown in Figures 1, 2, and 3.

[0032] The heat exchanger core 20 is block-shaped, divided into two parts 21 and 22 and placed in the sub-cavities 11 and 12 respectively, filling the cross-section of the sub-cavity channels. They are made of air filte...

Embodiment 2

[0037] Fig. 6 is the structural schematic diagram of embodiment 2 of the present invention, and this example is a kind of small-sized ventilator, is basically the same with example 1, and difference is:

[0038] First, the fan device 40 is included in this example, and the fan device 40 includes two fans 41 and 42, which are installed in the same casing of the heat exchanger, and are respectively installed outside the two inner side walls of the casing, and their air inlets are respectively connected to The air outlets 14c and 15c of the casing are connected; the fans 41 and 42 are centrifugal fans. Of course, other fans with higher total pressure can also be used, such as oblique flow or mixed flow fans with a total pressure above 100Pa. The ventilation system using this structure does not need to arrange fans in the pipeline. As an equivalent replacement, the air outlet of the fan can also be connected with the air inlet of the heat exchanger.

[0039] The second differenc...

Embodiment 3

[0042] Figures 7, 8 and 9 are structural principle diagrams of Embodiment 3 of the present invention, and Figure 7 is an axial sectional view. This is another structural form of the purification and energy-saving ventilator of the present invention, which includes a casing 50 , a heat exchanger core 60 , and an air distribution mechanism 70 . The casing 50 is box-shaped, with an air passage in the inner cavity, and air inlets 51j, 52j and air outlets 51c, 52c at both ends to communicate with the outside of the machine.

[0043] The heat exchanger core 60 is block-shaped, and the material used is the same as that of Embodiment 1, and it is entirely filled in the air passage, filling the cross-section of the passage.

[0044] The gas distribution mechanism 70 includes two gas distribution valves 71, 72 and a driving mechanism 73, and the driving mechanism 73 includes a transmission shaft 731 and a motor 732; The center of symmetry is the geometric center point of the heat excha...

Abstract

The invention discloses a method for purifying, energy saving and ventilating and a purification energy-saving ventilator, and particularly relates to a heat storage type heat exchanger which is used for ventilating indoors and outdoors for a building, and simultaneously purifying fresh air and recovering exhaust energy. The method is characterized in that heat exchange material in the heat exchanger is firmly fixed in a shell of the heat exchanger, and an air distribution mechanism is used for leading two paths of air to alternately pass through different parts of the heat exchange material of the heat exchanger in opposite directions; the heat exchange material is common air filtering cotton, and can exchange heat with air and prevent solid particles in the air from passing through when air passes through the heat exchange material, therefore the air can be purified during ventilation and exhaust energy recovery, and the functions of air disinfection and sterilization, humidification, temperature reduction and the like can be realized. The invention has the advantages of high heat exchange efficiency, simple and compact structure, small volume, low manufacturing cost and long service life, has multiple functions of energy recovery, air purification, humidification and temperature reduction, and provides an economic, efficient and easily popularized multifunctional fresh air ventilator for saving energy, ventilating and purifying air for commercial and household air conditioning rooms.

Description

technical field [0001] The invention relates to a gas heat exchanger for recovering the energy carried by the air during the gas convection exchange process, especially a heat storage heat exchanger used for indoor and outdoor air exchange of buildings, recovering exhaust energy and purifying and filtering the air while exchanging air. air machine. Background technique [0002] Air-conditioned rooms in buildings are often closed due to the needs of heat preservation and energy saving, and the air quality is very poor, resulting in the well-known air-conditioning disease. In order to protect people's health, the country has formulated the air quality standard GB / T18883-2002, which clearly stipulates that the indoor fresh air volume per capita should not be less than 30m per hour 3 . For this reason, a standard air-conditioning system must have sufficient fresh air volume, and the energy consumed for fresh air cooling and heating can reach about 40% of the total energy consu...
