Problems solved by technology

Take fresh air purification as an example. Considering the outdoor air pollution and smog, it is necessary to add a purification section in the fresh air unit. However, when the outdoor air quality is good, unnecessary air transmission and distribution energy consumption will be increased due to the existence of the unit purification section.
[0006] It can be seen that there is a contradiction between intermittent purification requirements and air transmission and distribution energy consumption in the application of combined air handling units

Embodiment Construction

[0011] For the first embodiment, the outdoor fresh air enters from the fresh air outlet (6), passes through the fresh air section (1), and mixes with the indoor return air entering from the return air outlet (7) in the return air section (2) and passes through the circulating self-cleaning function section (3), after the heat and humidity treatment section (4) and the fan section (5), it is delivered to the room by the air supply port (8). The circulating self-purification function section (3) is installed between the return air section (2) and the heat and humidity treatment section (4). When the air needs to be purified, the self-circulating air inlet valve (11) and the self-circulating air outlet The valve (12) is opened, and the self-circulating fan (9) draws air from the combined air handling unit and returns the air treated by the air purification device (10) to the combined air handling unit; when it is not necessary to purify the air , close the self-circulation fan (9...

Abstract

The invention relates to a combined type air treatment unit with a circular self-cleaning function, and belongs to the technical field of building environment and equipment engineering. The technicalscheme is provided for solving the contradictory problem of intermittent air purifying needs and air transmission and distribution energy dissipation in a full air conditioning system, on the basis ofa traditional combined type air treatment unit structure manner, a circular self-cleaning function segment capable of being started according to needs is added, the function segment pumps air from the combined type air treatment unit through a self-circulation fan and returns the air treated through an air purifying device to the combined type air treatment unit, through adding of the circular self-cleaning function segment, the combined type air treatment unit can obviously reduce the air transmission and distribution energy consumption on the premise of meeting the intermittent purifying needs, and the unit can be widely applied to the full air conditioning system with the intermittent purifying needs.

Description

Technical field: [0001] The invention relates to a combined air handling unit with a cycle self-purification function, which belongs to the technical field of building environment and equipment engineering. Background technique: [0002] The full-air air-conditioning system is a relatively common system form in the central air-conditioning system of buildings. It is mainly composed of combined air handling units, transmission and distribution pipelines and terminal air outlet equipment. As the core equipment of the all-air air conditioning system, the basic functional sections of the combined air handling unit are the heat and humidity treatment section and the fan section. It is necessary to increase the air treatment function section to realize functions such as sending fresh air to the room, filtering, sterilizing, disinfecting, and removing odors. [0003] The transmission and distribution energy consumption of fans in an all-air air-conditioning system accounts for a l...
