Embodiment 1

[0041] combine figure 1 As shown, an electrochemical compression heat exchange fresh air system according to an embodiment of the present invention includes a fresh air pipe set and an electrochemical compression refrigeration device 20; the fresh air pipe set includes a first fresh air passage 11 and a second fresh air passage 12; The first metal hydride heat exchanger 21 and the second metal hydride heat exchanger 22 of the electrochemical compression refrigeration device 20 are correspondingly arranged in the first fresh air passage 11 and the second fresh air passage 12 of the fresh air duct group respectively. By controlling the conduction and air intake of the first fresh air channel 11 or the second fresh air channel 12, it is ensured that the fresh air entering the room is always cold or hot.

[0042] Wherein, the first fresh air passage 11 is connected indoors and outdoors, and is introduced into the indoor passage after the outdoor air is purified and filtered. There...

Embodiment 2

[0058] In the electrochemical compression heat exchange fresh air system of the above-mentioned embodiment 1, when refrigeration is the main method, the heat of the metal hydride heat exchanger at the heating end cannot be exchanged. The air discharge channel has been improved in design.

[0059] combine figure 1 As shown, the electrochemical compression heat exchange fresh air system according to Embodiment 2 of the present invention is illustrated, and the fresh air duct set also includes a first air discharge channel 13 and a second air discharge channel 14 . The two ends of the first air discharge passage 13 are respectively the first indoor air inlet 131 and the first outdoor air outlet 132, and the third ventilation device 43 is arranged on the indoor air inlet 131; the second air discharge passage 14 The two ends are respectively the second indoor air inlet 141 and the second outdoor air outlet 142, and the fourth ventilation device 44 is arranged on the indoor air inl...

Embodiment 3

[0073] In the electrochemical compression heat exchange fresh air system of the above-mentioned embodiment 1, when refrigeration is the main method, the heat of the metal hydride heat exchanger at the heating end is wasted. Therefore, in the embodiment 3, the electrochemical compression refrigeration device The structures of the first hydrogenation metal heat exchanger 21 and the second hydrogenation metal heat exchanger 22 in 20 have been designed and improved to make full use of heat.

[0074] In the electrochemical compression heat exchange fresh air system of Embodiment 3, the fresh air pipe set further includes an air discharge channel. The position of the first metal hydride heat exchanger 21 of the electrochemical compression refrigeration device can be switched between the first fresh air channel 11 and the air discharge channel, and the position of the second metal hydride heat exchanger 22 can be between the first fresh air channel 11 and the air discharge channel. S...

Abstract

The invention discloses an electrochemical compression heat exchange fresh air system and a control method thereof, belonging to the field of fresh air systems. The fresh air system includes a fresh air pipeline group and an electrochemical compression refrigeration device. The fresh air pipeline group includes a first fresh air channel and a second fresh air channel; the first metal hydride heat exchanger and the second metal hydride heat exchanger of the electrochemical compression refrigeration device correspond to Set in the first fresh air channel and the second fresh air channel; according to the hydrogen reversing switching signal, control the conduction and air intake of the first fresh air channel or the second fresh air channel to ensure that the fresh air entering the room is always cold or hot. It not only realizes the adjustment of indoor temperature, but also realizes the introduction of indoor fresh air, reduces the operating noise, does not require refrigerant, is more green and environmentally friendly, and brings a new all-round comfortable experience of temperature adjustment and air quality improvement to the human body. Control method: receiving the hydrogen reversing switching signal sent by the electrochemical compression refrigeration device.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to an electrochemical compression heat exchange fresh air system and a control method. Background technique [0002] At present, with the development of industry, air pollution is becoming more and more serious, which brings more and more hidden dangers to people's health. Therefore, people pay more and more attention to the air quality in the places where they live and work, and the fresh air system came into being pregnancy. The fresh air system can circulate the indoor air. On the one hand, the indoor dirty air is discharged outside, and on the other hand, the fresh outdoor air is filtered and then input into the room, so that the room is always fresh and clean air. . [0003] At present, the simple fresh air system only has the function of introducing fresh air, and some fresh air systems include heat exchange devices to adjust the temperature of the fresh air enteri...
