Description

TECHNICAL FIELD

The displacement fresh air system is used to ensure the amount of fresh air, humidity and cleanliness in the room, and to maintain the positive pressure in the room. The displacement fresh air system includes a fresh air unit, a main air pipe and a fresh air mechanism. The fresh air is taken from the outdoor, filtered, cooled and dehumidified / heated and humidified by the fresh air unit, and then sent to the main air pipe, and then sent to the fresh air mechanism in each room through the branch pipe. The fresh air is distributed to each branch in the room by the fresh air distributor, and then sent to each room through the ground branch pipe.

[0003] The fresh air purification is completed by the multiple filtering mechanisms in the fresh air unit, such as at least two of the primary filter, the medium filter and the high-efficiency filter. The purified fresh air is sent to each room through the long main air pipe. If there is a leakage point in the middle, the treated fresh air will be polluted again. At the same time, due to the multiple filtering mechanisms, the resistance is concentrated in the fresh air unit, and the resistance of the main air pipe and the branch pipe in the room is relatively small. At this time, the heat pressure of the main air pipe has a great influence on the air distribution balance of each floor, which affects the uniformity of the air supply of each floor, and makes it difficult to adjust the terminal. In addition, the displacement fresh air system delivers fresh air with the same temperature and humidity to each floor, which is difficult to meet the individual needs of each room.

[0004] Therefore, a wind distributor and a displacement fresh air system are needed to solve the above problems. CONTENT OF THE INVENTION

[0039] When the resistance in the ventilation channel is large, a pressurized fan is optionally arranged in the ventilation channel, and the pressurized fan is located between the air inlet and the filtering structure. By turning on the pressurized fan, the smooth flow of fresh air can be ensured.

[0049] In an embodiment of the present application, a humidifier is arranged in the ventilation channel.

[0051] To realize personalized adjustment, optionally, a wind volume adjusting valve is arranged in the ventilation channel, and the wind volume adjusting valve is used to adjust the air volume of the air outlet.

[0052] In an embodiment of the present application, the wind volume adjusting valve comprises a plurality of rotatable blades, and the blades are of a split type or a straight type.

[0053] The use process of the air distributor will be further introduced below.

[0054] The air distributor is arranged between the branch pipe of the air supply mechanism and the air distribution box, and the air inlet and the air outlet are respectively communicated with the branch pipe and the air distribution box.

When the air distributor device is more and the resistance is larger, a pressure fan is used.

[0055] The present application also provides a displacement type fresh air system, comprising the air distributor as described above.

[0056] By adopting the aforementioned displacement ventilation system and installing an air distribution box on the air supply mechanism, the structure of the ventilation unit used in conjunction with the air supply mechanism can be simplified. Only a pre-filter needs to be installed in the ventilation unit, and the filtration function of other filters eliminated from the ventilation unit can be achieved through the air distribution box, ensuring that only clean fresh air enters each room. Even if there is pollution during the fresh air delivery process, purified fresh air can still be provided after filtration and purification by the air distribution box. At the same time, the reduction of filtration equipment in the ventilation unit reduces the air resistance within the unit. The addition of an air distribution box increases the resistance of the indoor air supply mechanism, which is more conducive to adjusting the air volume balance of each floor and each household, achieving uniform air supply, and reducing the difficulty of terminal adjustment.

The distribution box is positioned between the branch ducts and the distribution box of the air supply mechanism. The branch ducts supply air to the distribution box, and the airflow entering from the inlet passes through a filtration structure and is discharged from the outlet, then enters the room through the distribution box. Using this air supply mechanism ensures both the cleanliness of the fresh air and the uniformity of the airflow from each air supply mechanism connected to the main duct.

[0059] Figure 3 This is a schematic diagram of the displacement ventilation system used in a specific embodiment of this application. Figure 3 As shown, the displacement ventilation system includes: a fresh air unit, a main air duct, and an air supply mechanism.

[0060] The fresh air handling unit is equipped with a pre-filter or a medium-efficiency filter at the air inlet. The fresh air handling unit includes a fresh air inlet and a fresh air outlet. From the fresh air inlet to the fresh air outlet, a pre-filter or a medium-efficiency filter, a thermostat, a humidifier, and a blower are installed in sequence. After the fresh air is filtered, the temperature and humidity are adjusted, and the blower delivers the fresh air into the main air duct.

The branch pipes of the air supply mechanism are connected to the main air duct, and the air distribution box of the air supply mechanism is installed indoors.
