Description of the Drawings

[0031] The following further details the specific embodiments of the present utility model in conjunction with the drawings, where:

[0032] Figure 1 is the structural schematic diagram of the present utility model.

Specific Embodiments

[0033] The following details the embodiments of the present utility model in conjunction with the drawings.

[0034] As Figure 1 shown, an energy-saving and emission-reducing healthy air conditioning circulation system of the present utility model includes a workshop 1, an air conditioning room 2, an air conditioning device 3, a fresh air supplement device 4, and a hot waste gas emission device 5;

[0035] The workshop 1 is provided with a cold air outlet duct 11 and a hot air return duct 12. The cold air outlet duct 11 is provided with cold air outlets 111 for communicating with the workshop 1 at reasonable intervals. The hot air return duct 12 is provided with hot air return inlets 121 for communicating with the workshop 1 at reasonable intervals.

[0036] The air conditioning device 3 is arranged in the air conditioning room 2. The cold air of the air conditioning device 3 enters the workshop 1 through the cold air outlet 111 via the cold air outlet duct 11, and then enters the air conditioning device 3 through the hot air return inlet 121 via the hot air return duct 12 to realize the refrigeration cycle, thereby making the air conditioning circulating air form an independent one-way air flow.

[0037] The fresh air supplement device 4 is arranged in the air conditioning room 2. The fresh air supplement device 4 is used to inject fresh air outside the air conditioning room 2 into the hot air return duct 12 to supplement fresh air to the air conditioning device 3.

[0038] The hot waste gas discharge device 5 is arranged in the workshop 1 to discharge the hot waste gas in the workshop 1 to the outside of the workshop 1. By placing the air conditioning device in an independent air conditioning room, and at the same time, the cold air of the air conditioning device enters the workshop through the cold air outlet via the cold air outlet duct, and then enters the air conditioning device through the hot air return inlet via the hot air return duct to realize the refrigeration cycle. The scientific setting makes the air conditioning circulating air form an independent one-way air flow, which can effectively reduce the fresh air supplement amount and the energy consumption of the air conditioning device. In addition, the hot waste gas in the workshop is discharged to the outside of the workshop through the hot waste gas discharge device, effectively reducing the influence of the hot waste gas in the workshop on the cold air in the workshop, improving the refrigeration effect, realizing energy conservation and emission reduction, and providing a good and healthy working environment for the operators.

[0039] Compared with the prior art in which the layout of the cold air outlets and hot air return inlets in the equipment area and the manual operation area is unreasonable, forming a non-unidirectional air flow, no separation of cold and heat, and maintaining the workshop at a relatively low temperature through the air conditioning device to suppress odors to ensure the comfort of the workshop, in the present invention, the hot waste gas is discharged to the outside of the workshop through the hot waste gas discharge device, so the air conditioning device does not need to maintain the workshop at a relatively low temperature to ensure the comfort and odorless of the workshop environment, realizing energy conservation and emission reduction.

[0040] As Figure 1 shown, the hot air return inlet 121 is located above or on the side of the cold air outlet 111 so that the air conditioning circulating air forms an independent one-way air flow, which can effectively prevent the cold air blown out from the cold air outlet from entering the hot air return inlet immediately, making the cold air of the air conditioning distribute and fill each angle of the manual operation area where the workshop personnel are concentrated more accurately, and improving the utilization rate of the cold air of the air conditioning.

[0041] As Figure 1As shown, the hot air return opening 121 and the cold air outlet 111 are both located at the top of the workshop 1. The cold air outlet 111 is arranged downward, and the hot air return opening 121 is located on the side of the cold air outlet 111, which is beneficial for the cold air of the air conditioner to better blow towards the working area of people. At the same time, by using the fact that the cold air flow becomes larger (entering the workshop) and the hot air flow becomes smaller (circulating and returning), the residence time of the cold air of the air conditioner in the workshop is extended.

[0042] As Figure 1 shown, the fresh air supplement device 4 includes a fresh air supplement window 41 provided in the air conditioning room 2 and a fresh air supplement pipeline 42 for connecting the fresh air supplement window 41 with the hot air return pipeline 12. The fresh air supplement pipeline 42 is provided with a fresh air supplement control valve 43 for controlling the air intake volume of the fresh air supplement pipeline 42. The workshop 1 is provided with an exhaust gas detection sensor 13 for detecting the content of hot exhaust gas in the workshop 1 and / or a temperature detection sensor 14 for detecting the temperature in the workshop 1. In this embodiment, the exhaust gas detection sensor 13 detects the content of hot exhaust gas in the workshop to correspondingly control the fresh air supplement control valve 43 to adjust the air intake volume of the fresh air supplement pipeline 42, that is, to avoid the situation of excessive or too small air supplement volume when ensuring that the workshop temperature and the content of hot exhaust gas are at the preset values, so as to achieve energy conservation and emission reduction. Among them, the fresh air supplement control valve 43 can be controlled to act correspondingly by a driving motor, and then the air intake volume is controlled and adjusted. The exhaust gas detection sensor 13 can be a V0Cs detection sensor or an odor detection sensor, etc.

[0043] In order to ensure air quality to provide a healthy and comfortable working environment, a sterilization device 15 or an adsorption and filtration device is provided at the position of the air conditioning device 3 and / or the fresh air supplement device 4. Among them, the sterilization device can be an ultraviolet sterilization lamp, etc., and the adsorption and filtration device can be an activated carbon adsorption box, etc. In this embodiment, the sterilization device 15 or the adsorption and filtration device can be provided at a position close to the cold air outlet of the cold air outlet pipeline 11.

[0044] As Figure 1 shown, in order to improve the hot exhaust gas emission efficiency, the hot exhaust gas emission device 5 includes a hot exhaust gas emission pipeline 51 provided in the workshop 1 and used for communicating the inner side of the workshop 1 with the outer side of the workshop 1, and a hot exhaust gas exhaust fan 52 for discharging the hot exhaust gas in the workshop 1 to the outer side of the workshop 1 through the hot exhaust gas emission pipeline 51. The hot exhaust gas emission device 5 further includes a gas collecting hood 53 or a gas collecting window that is communicated with the hot exhaust gas emission pipeline 51 and used for accurately collecting the hot exhaust gas in the equipment area.

[0045] As Figure 1 shown, in order to meet the national environmental protection governance requirements for carbon emission reduction, the workshop 1 is provided with a hot exhaust gas treatment device 6 for treating the hot exhaust gas discharged through the hot exhaust gas emission pipeline 51.

[0046] As Figure 1As shown in the figure, it further includes a cold, heat and waste gas separation device 7 installed in the workshop 1. The cold, heat and waste gas separation device 7 is used to separate the manual operation area and the equipment area in the workshop 1, so as to effectively separate the air-conditioning circulating air from the heat and waste gas generated by the equipment operation in the equipment area.

[0047] In the present utility model, the workshop is a relatively large and large-area workshop, and high-power air conditioners are required for refrigeration. For example, for a factory workshop with an area of 2,800 square meters and a ceiling height of 3 meters, usually 2 air-conditioning units with 200 horsepower are required for refrigeration.

[0048] Among them, GMP is the English abbreviation for Good Manufacturing Practice for Drugs, which is the criterion for the overall quality management and control of the production of drugs, foods and cosmetics.

[0049] According to GB50073-2013 "Code for Design of Clean Plant":

[0050] To ensure that the fresh air volume supplied to the workshop is not less than 40 cubic meters per person per hour and to maintain the fresh air to be compensated for the loss of indoor air leakage and exhaust to ensure the indoor positive pressure (generally 5PA-10PA) static pressure difference: The determination of the fresh air volume in the workshop is based on the requirements of Article 2.2.4 of GMP. For non-unidirectional flow workshops, it is 10%-30% of the total supply air volume, while for unidirectional flow (the air flow flows in a single direction) workshops, only 2%-4% of the total supply air volume is required.

[0051] For example, the workshop temperature is 20-24°C, the relative humidity is 45%-60%, and there are no toxic and harmful substances and no peculiar smell:

[0052] 1. In order to ensure the above-mentioned fresh air volume in the workshop, the more air volume supplemented by the fresh air supplement device, the more energy consumption. Therefore, the present utility model realizes the refrigeration cycle by independently adding an indoor hot waste gas discharge device 5, and the cold air of the air-conditioning device 3 enters the workshop 1 through the cold air outlet pipe 11 from the cold air outlet 111, and then enters the air-conditioning device 3 through the hot return air port 121 and the hot return air pipe 12, so as to form an independent unidirectional air flow of the air-conditioning circulating air, realizing the transition from a non-unidirectional flow workshop to a unidirectional flow workshop, and reducing the fresh air volume supplement from 10%-30% to 2%-4% of 5-7 times (as Figure 1 shown, the fresh air supplement device 4 only needs to supplement 2%-4% of the fresh air volume), and a clean air-conditioning circulation system that is both energy-saving and emission-reducing and healthy and hygienic can be realized. For example, the hot waste gas discharge device 5 discharges 3% of the air volume in the workshop 1, and the fresh air supplement device 4 needs to supplement 4% of the fresh air volume to ensure the indoor positive pressure static pressure difference.

[0053] 2. By independently adding an indoor hot waste gas emission device 5, the super-high temperature and odor-containing waste gas with harmful substances in the workshop can be collected where it is produced, effectively preventing it from spreading throughout the workshop, ensuring clean and fresh air in the intensive human working area, and enabling the super-high temperature waste gas to no longer consume electricity for refrigeration through the air conditioning device and no longer have odor-containing waste gas deposited in the fresh air area of the workshop. Thus, a relatively high indoor temperature can be set to achieve energy conservation and emission reduction.

[0054] 3. The air conditioning device controls the heating and cooling inside the workshop, and the intelligent fresh air system (such as the fresh air supplement device 4 and the hot waste gas emission device 5) controls the air freshness. For workshops with plastics, chemicals, circuit boards, etc. that contain VOCs and have strong odors, connecting the hot waste gas discharge pipe to an activated carbon adsorption box can meet the national environmental protection governance requirements for carbon emission reduction.

[0055] 4. The intelligent fresh air system includes controlling the amount of fresh air supplemented by the air conditioning device and controlling the independent collection and emission of hot waste gas different from the air conditioning device.

[0056] 5. The distribution and size of the cold air outlets, hot air return outlets, and hot waste gas collection and discharge outlets in the entire workshop follow the principle of ensuring a unidirectional air flow in the workshop to better achieve energy conservation and emission reduction.

[0057] 6. The fresh air supplement device can manually adjust the fresh air supplement control valve according to the air freshness in the human working area of the workshop; or automatically control the fresh air supplement amount of the fresh air supplement device by intelligently monitoring the concentration of odors, non-methane total hydrocarbons, or VOCs in the workshop through big data. The supplemented fresh air can prevent dust from entering the workshop through a primary filter, and the supplemented fresh air can also be sterilized and deodorized by ultraviolet lamps before entering the air conditioning device for refrigeration and air supply.

[0058] 7. The cold air outlet pipe can be internally equipped with an ultraviolet germicidal lamp for continuous sterilization and deodorization, making the cold air from the air conditioning device entering the workshop fresh and healthy. The ultraviolet germicidal lamp is installed inside the cold air outlet pipe, and the light does not shine on the operators in the human working area, avoiding harm to the operators. Thus, all-weather circulating sterilization and deodorization are achieved to ensure fresh, healthy, and safe air in the workshop.

[0059] 8. To obtain cleaner, healthier, and safer unidirectional flow air in the workshop with a smaller fresh air supplement amount, further use the barrier soft curtain of the heat and cold and waste gas separation device 7 to block the area in the equipment area that generates strong hot gas, odors, and toxic gases (the barrier soft curtain is hung from the top of the workshop and extends towards the bottom of the workshop and is located between the human working area and the equipment area to separate the two, blocking the hot waste gas in the equipment area from flowing into the human working area), and use a gas hood 53 connected to the hot waste gas discharge channel 51 to achieve precise collection and discharge.

[0060] 9. By having a fresh, healthy and odorless manual working area in the workshop, the temperature in the workshop can be adjusted to 20 - 24 °C at this moment (a higher upper limit can also be set), which can also ensure the comfort of the workshop personnel, thus achieving energy conservation and emission reduction by raising the refrigeration temperature of the air conditioning device.

[0061] A working method of an energy-saving and emission-reducing healthy air-conditioning circulation system of the present utility model. This working method is applied to an energy-saving and emission-reducing healthy air-conditioning circulation system as described above. The working method includes:

[0063] When the temperature and the content of hot waste gas in Workshop 1 are at the preset values, the cold air of the air conditioning device 3 enters Workshop 1 through the cold air outlet pipe 11 from the cold air outlet 111, and then enters the air conditioning device 3 through the hot return air outlet 121 and the hot return air pipe 12 to realize the refrigeration cycle. Furthermore, the air-conditioning circulating air forms an independent one-way air flow. At this time, the fresh air supplement device 4 and / or the hot waste gas discharge device 5 can be frequency-adjusted to reduce speed or stop working; or the fresh air supplement device 4 works to supplement fresh air to the air conditioning device 3, and the hot waste gas discharge device 5 can be frequency-adjusted to reduce speed or stop working;

[0064] When the temperature and the content of hot waste gas in Workshop 1 exceed the preset values, the cold air of the air conditioning device 3 enters Workshop 1 through the cold air outlet pipe 11 from the cold air outlet 111, and then enters the air conditioning device 3 through the hot return air outlet 121 and the hot return air pipe 12 to realize the refrigeration cycle. Furthermore, the air-conditioning circulating air forms an independent one-way air flow; the fresh air supplement device 4 works to supplement fresh air to the air conditioning device 3; the hot waste gas discharge device 5 works to discharge the hot waste gas in Workshop 1 to the outside of Workshop 1.

[0065] When the workshop can correspondingly turn on the air conditioning device 3, the fresh air supplement device 4 and the hot waste gas discharge device 5 according to different production scenarios to achieve different temperatures at different positions in the equipment area and the manual working area. For example, in the injection molding and blow molding processes, the equipment needs to be heated to melt the plastic, while the manual working area needs to be cooled to ensure the comfort of the staff. This working method is applied to the above-mentioned energy-saving and emission-reducing healthy air-conditioning circulation system, which can effectively achieve energy conservation and emission reduction and provide a comfortable and healthy working environment.

[0066] The present utility model can also be applied to places such as hospitals, conference halls, waiting rooms, high-speed rail carriages, restaurants, etc., which can effectively achieve energy conservation and emission reduction and provide a comfortable and healthy working, living, learning and resting environment.
