Description
Technical Field
The invention relates to the technical field of passive rooms, in particular to a fresh air device for a passive room.
Background
With the rapid development of global economy, the problem of energy shortage is increasingly prominent, and energy conservation becomes a life concept advocated by various countries. In recent years, our country has made higher and higher demands for energy conservation and environmental protection of new buildings, and therefore, the concept of passive houses has been proposed and rapidly developed in recent years.
The passive house needs to improve the heat preservation, heat insulation and air tightness of the building to the maximum extent due to the requirement of energy conservation, so the passive house is equivalent to a highly closed space, and cannot live without a fresh air system. The fresh air system in the prior art has low efficiency and serious energy consumption, and does not accord with the design concept of high efficiency and energy saving of a passive house.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a passive room fresh air device which is mainly suitable for energy-saving places such as passive rooms and the like, through the optimized design of materials and structures, on the basis of the existing fresh air system, a graphene heat exchange core is selected as a main part of a heat exchanger, and a graphene membrane material is selected as a filter layer, so that the purposes of better heat exchange and air purification are achieved, the requirement of a closed space of the passive room on fresh air is met, and meanwhile, the effects of heat preservation, moisture preservation and energy saving are achieved.
In order to achieve the above purpose, the invention comprises the following technical scheme: a passive room fresh air device comprises a fresh air pipeline from a fresh air inlet to a fresh air outlet, an exhaust pipeline from an exhaust air inlet to an exhaust air outlet, and a heat exchanger which enables the fresh air pipeline and the exhaust pipeline to cross and pass through and to be isolated from each other, wherein a heat exchange core in the heat exchanger is made of graphene high polymer materials; the fresh air duct further includes:
the filter is connected with the fresh air inlet and consists of a first filter screen and a second filter screen;
the defrosting fan is arranged between the first filter screen and the second filter screen;
a first fan connected between the filter and the heat exchanger;
the deodorizing purifier is positioned at the air outlet end of the heat exchanger and consists of a graphene coating filter screen, an HEPA filter screen and a static electricity removing filter screen;
the atomizing humidifier is positioned between the odor removal purifier and the fresh air outlet and is connected with a water tank;
the exhaust duct still includes:
the second fan is arranged between the exhaust air inlet and the heat exchanger;
the sound-insulation dust-absorption filter screen is arranged at the air inlet of the second fan and consists of a graphene honeycomb layer, an activated carbon layer and a surfactant layer;
the exhaust filter screen is arranged at the air exhaust outlet.
Preferably, the first filter screen is a multi-layer nonwoven filter screen.
Preferably, the second screen comprises a pleated composite PM2.5 screen and an activated carbon screen.
Furthermore, a flow equalizer is arranged at the position of the fresh air outlet. Optionally, a flow equalizer is installed for further noise reduction.
Preferably, the first fan is an EC motor type centrifugal fan. The fan has the function of multi-stage regulation, and has high power, good energy saving performance and low noise.
Furthermore, a temperature and humidity sensor and a control quality detection sensor are further arranged at the fresh air outlet.
Furthermore, the fresh air system is connected with the central control unit.
Has the advantages that: the fresh air device provided by the invention has certain beneficial effects on structure and material selection.
Firstly, the traditional fresh air system only has the function of providing fresh air and cannot meet the requirements of a passive room on constant temperature and humidity, high efficiency and energy conservation; according to the fresh air device, the graphene material is used as the exchange core of the total heat exchange system, compared with the heat exchange core made of common materials, the total heat exchange efficiency is improved by more than 15%, the fresh air device has better water permeability, and the condition that frost is prevented from blocking an air channel in a low-temperature environment in winter is guaranteed; and the graphene film has small surface resistance, dust is not easy to stay, and the self-cleaning function is obvious.
And secondly, a graphene filtering interlayer is also selected for the material of the filtering layer. The active carbon has certain adsorption capacity, but only temporarily adsorbs certain pollutants, and when the temperature and the wind speed are raised to a certain degree, the adsorbed pollutants can be dissociated and enter the room again to cause secondary pollution. The adsorption capacity of the graphene is more than 3 times that of the activated carbon, toxic gases such as formaldehyde, toluene and the like PM2.5 and the like are efficiently adsorbed, then the toxic gases such as formaldehyde and the like are decomposed into non-toxic water and carbon dioxide, and the sterilization rate is 99%; meanwhile, due to the stable atomic structure of the graphene, pollutants can be released secondarily only in a high-temperature box at 200 ℃; therefore, the filter element or the filter layer made of the graphene material has a better technical effect.
