Abstract
The invention relates to a combined air treatment unit with a circulating self-cleaning function, and belongs to the technical field of building environment and equipment engineering. The invention provides a technical scheme aiming at the contradiction between intermittent air purification demand and air transmission and distribution energy consumption in an all-air conditioning system. By adding the circulating self-cleaning functional section, the combined air treatment unit can obviously reduce the energy consumption of air transmission and distribution on the premise of meeting the intermittent purification requirement. The invention can be widely applied to the all-air conditioning system with intermittent purification requirement.
Description
The technical field is as follows:
the invention relates to a combined air treatment unit with a circulating self-cleaning function, and belongs to the technical field of building environment and equipment engineering.
Background art:
the full air conditioning system is a common system form in a building central air conditioning system and mainly comprises a combined air processing unit, a transmission and distribution pipeline and a tail end air port device. As the core equipment of the full-air conditioning system, the basic function sections of the combined air treatment unit are a heat and humidity treatment section and a fan section, the combined air treatment unit bears the cold and heat loads of rooms by conveying air subjected to centralized treatment to each room, and simultaneously can realize the functions of supplying fresh air to the rooms, filtering, sterilizing, disinfecting, removing peculiar smell and the like by adding the air treatment function sections according to the needs.
The fan transmission and distribution energy consumption of the all-air conditioning system accounts for a large proportion of the energy consumption of the air conditioner, and in order to reduce the transmission and distribution energy consumption and the use cost, generally, an air handling unit only comprises a necessary coarse and medium-efficiency filtering section, a heat and humidity treatment functional section and a fan section, and only in part of all-air conditioning systems with special requirements, such as hospital buildings, the air handling unit can be provided with functional sections for efficient filtering, sterilization, disinfection, odor removal and the like, and naturally, the increase of the air handling functional section is bound to be at the cost of consuming more fan transmission and distribution energy consumption and increasing the use cost.
In recent years, due to the large-scale outbreak of the epidemic situations of SARS virus, new coronavirus and the like, people have come to pay more and more attention to the epidemic prevention problem of the whole air conditioning system. According to the suggestion of the world health organization, during the building epidemic prevention period, the fresh air is introduced in a large amount, or the return air is filtered and purified efficiently, so that the pollutants in the air are diluted by ten thousand times, and the building space can be considered to be in an epidemic situation safe state. If a large amount of fresh air is introduced, the problem of overlarge energy consumption of fresh air treatment exists; if direct mount high efficiency filter in the unit, carry out high efficiency filtration purification to the return air, because high efficiency filter's resistance is very big, need great circulating air volume in order to reach the epidemic prevention effect simultaneously, will lead to the fact huge air transmission and distribution energy consumption certainly, also can bring unnecessary air transmission and distribution energy consumption owing to increased the resistance of air treatment function section in addition during non-epidemic situation.
Not only building epidemic prevention, but other air handling units with non-continuous purification requirements also have similar problems. For example, fresh air purification needs to be performed by adding a purification section in a fresh air unit in consideration of the conditions of outdoor air pollution, haze and the like, but in the case of excellent outdoor air quality, unnecessary air transmission and distribution energy consumption is increased due to the existence of the purification section of the unit.
Therefore, the combined air treatment unit has contradiction between intermittent purification requirement and air transmission and distribution energy consumption. The invention provides a solution to the contradiction, and by implementing the technical scheme, the energy consumption of air transmission and distribution can be obviously reduced on the premise of meeting the intermittent purification requirement.
The invention content is as follows:
on the basis of the structural form of the traditional combined air treatment unit, the invention is additionally provided with a circulating self-cleaning functional section, and the circulating self-cleaning functional section mainly comprises a self-circulating fan, an air purification device (which can have one or more functions of filtering, sterilizing, disinfecting, removing peculiar smell and the like), a self-circulating air inlet valve, a self-circulating air outlet valve and a monitoring control device, as shown in attached figures 1 and 2. When air needs to be purified, the self-circulation air inlet and outlet valve is opened, the self-circulation fan draws air from the combined air treatment unit and returns the air treated by the air purification device to the combined air treatment unit; and when the air does not need to be purified, closing the self-circulation fan and the air inlet and outlet valves. The monitoring control device can control the opening and closing of the self-circulation fan and the air inlet and outlet air valve as required, monitor the air quality and adjust the air quantity of the self-circulation fan according to the monitoring result. By adding the circulating self-cleaning functional section, the combined air treatment unit can obviously reduce the energy consumption of air transmission and distribution on the premise of meeting the intermittent purification requirement.
