Fresh air purifying system composed of air conditioner and graphene nanofiber membrane total heat exchanger

Abstract

The invention relates to the technical field of fresh air purification systems, and particularly discloses a fresh air purifying system composed of an air conditioner and a graphene nanofiber membranetotal heat exchanger. The system comprises the air conditioner and the total heat exchanger. The total heat exchanger comprises a shell, a fiber membrane is fixedly connected in the shell, an exchange channel is fixedly connected to the position, on the surface of the fiber membrane, in the shell, a flow limiting mechanism is movably connected in the exchange channel, adjusting plates are movablyconnected to the two sides of the exchange channel, spring rods are movably connected into the adjusting plates, the ends, away from the adjusting plates, of the spring rods are movably connected with blockage plates, and when the adjusting plates make contact with the blocking plates, airflow can directly enter the exchange channel, at the moment, the blockage plates are away from the adjustingplates, a flexible pipe is opened, the airflow can enter the shell again, the above operation is repeated, the temperature difference between fresh air entering a room and the airflow existing in a room cannot be too large while the gas normal exchange is ensured, the temperature of introduced fresh air is close to the room temperature, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of fresh air purification systems, and specifically discloses a fresh air purification system composed of an air conditioner and a graphene nanofiber membrane total heat exchanger. Background technique [0002] A total heat exchanger usually refers to a fresh air, exhaust air ventilation equipment that contains a full heat exchange core. There is a temperature difference and a steam partial pressure difference in the airflow on both sides of the partition, and the heat and mass transfer phenomenon occurs when the two airflows pass through the partition, causing a total heat exchange process; [0003] The most important component in a total heat exchanger is the graphene exchange membrane. Although the fiber membrane produced by the existing technology can meet its work requirements, from the perspective of environmental protection, the fiber membrane does not achieve energy saving. , and the existing total ...

Problems solved by technology

[0003] The most important component in a total heat exchanger is the graphene exchange membrane. Although the fiber membrane produced by the existing technology can meet its work requirements, from the perspective of environmental protection, the fiber membrane does not achieve energy saving. , and the existing total heat exchanger does not have corresponding components to cooperate with its work, resulting in direct contact between indoor and outdoor hot and cold air on the surface of the fiber membrane;

[0004] In the case of only relying on the fiber membrane to work, whether it is winter or summer, the temperature of the fresh air introduced into the room through the total heat exchange core will not become close to room temperature, which indirectly increases energy consumption and reduces the work of the total heat exchanger. efficiency, so a graphene nanofiber membrane module based on total heat exchange and purification device came into being
