[0007] The module composed of the bypass air valve, the air valve mounting plate, and the bypass module frame is a whole module, the size of the whole module is the same as the shape of the fresh air ventilation core in the set, so that the bypass valve module can be used universally in the existing commercial fresh air ventilator, the whole set does not need to be redesigned, the workload of non-standard products is reduced, and the timeliness of delivery is improved.

[0008] The bypass air valve is in the middle of the bypass module frame.

[0009] The bypass air valve is at one end of the bypass module frame.

[0010] Compared with the prior art, the bypass air valve, the air valve mounting plate and the bypass module frame form an integral module. The size of the module is designed to be the same as the shape of the fresh air exchange core in the unit, so that it can be used for existing commercial fresh air exchangers without the need to redesign the entire unit.

[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0017] Embodiment 1:

[0018] As Figure 1 and Figure 3As shown, a bypass valve module for a fresh air ventilator is used in a fresh air ventilator set, which comprises a fresh air fan 1, a heat exchange core 2 and an exhaust fan 3. One side of the heat exchange core 2 is a fresh air inlet cavity, and the fresh air fan 1 is arranged on the other side of the heat exchange core 2. The other side of the heat exchange core 2 is a fresh air outlet cavity, and the exhaust fan 3 is arranged on the other side of the heat exchange core 2. The rear end of the heat exchange core 2 is provided with a bypass fresh air channel.

[0019] The bypass valve module comprises a bypass module frame 4, a bypass air valve 5 and a bypass air valve fixing plate 6, the bypass air valve fixing plate 6 is fixedly arranged in the bypass module frame 4, and the bypass air valve 5 is fixedly arranged on the bypass air valve fixing plate 6. The bypass air valve 5 is in the middle of the bypass module frame 4, or the bypass air valve 5 is at one end of the bypass module frame 4.

[0020] The bypass fresh air channel is provided with a fresh air ventilation core cavity, the shape and size of the bypass valve module match the fresh air ventilation core cavity, and the bypass valve module is replaceably embedded and inserted in the fresh air ventilation core cavity, which has the characteristics of simple structure, strong universality and low cost.

[0021] When the bypass air valve 5 is closed, outdoor fresh air is brought into the heat exchange core 2 through the fresh air inlet cavity under the driving of the fresh air fan 1 for heat exchange, and then enters the indoor through the fresh air outlet cavity under the driving of the fresh air fan 1. When the bypass air valve 5 is opened, part of the outdoor fresh air is brought into the heat exchange core 2 through the fresh air inlet cavity under the driving of the fresh air fan for heat exchange, and the other part of the outdoor fresh air directly enters the bypass fresh air channel through the bypass air valve 5. Then, the fresh air in the heat exchange core 2 after heat exchange and the fresh air directly entering the bypass fresh air channel are mixed and enter the indoor through the fresh air outlet cavity under the driving of the fresh air fan 1.

[0022] The module composed of the bypass air valve 5, the air valve mounting plate and the bypass module frame 4 is a whole module, the size of the whole module is the same as the shape of the fresh air ventilation core in the set, so it can be used for existing commercial fresh air ventilators, without the need to redesign the whole set, reducing the workload of non-standard products and speeding up the timeliness of delivery.

[0023] The bypass air valve 5 is in the middle of the bypass module frame 4.

[0024] Embodiment 2:

[0025] As shown in Figure 2 The bypass air valve 5 is at one end of the bypass module frame 4.

[0026] The same as embodiment 1.
