Description
Technical Field
The utility model relates to a new trend field, in particular to indoor carbon dioxide content control device.
Background
Since the 21 st century, the income level of the people is gradually improved, the requirement of the household common heat pump type air conditioner can not be met only by the refrigerating and heating functions, and each family not only demands the indoor proper temperature and humidity, but also needs the requirements of oxygen content and quality control.
In the current air conditioning system, the most common is that the fresh air is directly supplemented to replace the indoor air, so as to dilute the indoor carbon dioxide and ensure the indoor oxygen content.
The carbon dioxide content in the outdoor fresh air is 350-450ppm, excessive supplement is not beneficial to the oxygen content, and meanwhile, the indoor cold and heat load is increased, so that the direct supplement of the fresh air has certain limitation.
The application provides a scheme of supplementing fresh air to ensure indoor oxygen content.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing an indoor carbon dioxide content control device can the indoor carbon dioxide content of accurate detection, and the new return air of control is compared, and the new trend is introduced in proper amount, reaches and has both improved indoor oxygen content, reduces cold and hot load again.
The technical scheme is as follows: the utility model relates to an indoor carbon dioxide content control device, which comprises a box body structure, wherein one end of the box body structure is provided with a fresh air inlet and a return air inlet, the other end of the box body structure is provided with an air supply outlet, the fresh air inlet is connected outdoors, the return air inlet is connected indoors, and the air supply outlet is connected indoors; in the interior of the box body structure, the fresh air inlet and the return air inlet are respectively connected with a fresh air electric valve and a return air electric valve, and the fresh air electric valve and the return air electric valve are electrically connected with the control module; and a filter and a fan are sequentially arranged behind the fresh air electric valve and the return air electric valve, and the fan is connected with the air supply outlet.
Preferably, a carbon dioxide sensor for monitoring the content of carbon dioxide is arranged at the outlet of the fresh air electric valve and the outlet of the return air electric valve, and the carbon dioxide sensor is electrically connected with the control module.
Preferably, the fresh air electric valve and the return air electric valve adopt proportional machine sub-regulating valves, and the opening regulating range is between 0% and 100%.
Preferably, the opening degree of the fresh air inlet adjusted by the fresh air electric valve is larger than the opening degree of the return air inlet adjusted by the return air electric valve.
Preferably, the control module is a PLC controller using a PID algorithm.
Has the advantages that: the utility model discloses a setting up of carbon dioxide sensor can real-time supervision get into indoor air situation, adjusts new return air ratio, when improving indoor air oxygen content, can reduce cold and hot load again, reduces the loss.

Detailed Description
As shown in fig. 1, for the utility model discloses a structural schematic diagram, in this embodiment, the utility model discloses a box structure, one end at box structure is provided with fresh air inlet 1 and return air inlet 2, the other end is provided with supply-air outlet 7, fresh air inlet 1 is connected outdoor, return air inlet 2 is connected indoor, supply-air outlet 7 is connected indoor, inside at box structure, fresh air inlet 1 is connected with return air inlet 2 with fresh air motorised valve 3 and return air motorised valve 4 respectively, outdoor new trend passes through fresh air inlet 1 with return air inlet 2 with indoor return air after, in getting into same pipeline through fresh air motorised valve 3 and return air motorised valve 4, be provided with carbon dioxide sensor 8 in the pipeline, after air process filter 5 through carbon dioxide sensor 8, under the effect of fan 6, send into indoor again through supply-air outlet 7.
In this embodiment, the fresh air electric valve 3 and the return air electric valve 4 are respectively electrically connected to a PLC controller using a PID algorithm, the PLC controller controls the fresh air electric valve 3 and the return air electric valve 4 to adjust the openings of the fresh air inlet 1 and the return air inlet 2 through data of carbon dioxide content in the air entering the room collected by the carbon dioxide sensor 8 to meet the concentration standard of the carbon dioxide in the room to ensure fresh air and smooth breathing in the room, meanwhile, since the carbon dioxide content in the outdoor fresh air is 350-, the proportion of the fresh air inlet 1 is mainly adjusted, the return air inlet 2 is assisted, and accordingly the indoor air can reach the standard and the air supply is stable.
