Description

Technical Field

[0001] This utility model relates to the field of fresh air technology, specifically to a workshop air supply system and a production workshop. Background Technology

[0002] Existing solar cell production workshops rely on energy-intensive refrigeration systems to control temperature and humidity in summer. They use chilled water produced by the refrigeration machines as a heat exchange source for air conditioning, thereby providing dry and cool air inside the workshop. The air conditioning system in such workshops accounts for more than 55% of the electricity consumption, resulting in excessively high operating costs.

[0003] Furthermore, due to the need for process wastewater collection, culverts are usually installed underground in the workshop to construct wastewater pipe corridors. However, in reality, the wastewater pipe corridors occupy less than 20% of the culvert space, resulting in low space utilization of the underground culverts and ineffective use of their constant temperature characteristics.

[0004] The purpose of this invention is to provide a workshop gas supply system that can significantly reduce workshop energy consumption and improve the utilization rate of underground culverts.

[0005] Another objective of this invention is to provide a production workshop that can significantly reduce energy consumption and improve the utilization rate of underground culverts.

The air supply duct is used to draw in outside air through the inlet end and deliver it to the workshop air conditioner through the outlet end. The outlet of the workshop air conditioner is connected to the interior space of the workshop. The air supply duct includes an underground culvert section for ground source heat exchange of the flowing air.

[0007] In an optional embodiment, a cooling rod is installed in the underground culvert section, the cooling rod is inserted into the ground, and the portion of the cooling rod inside the underground culvert section is provided with heat exchange fins.

[0010] In an optional embodiment, the workshop air supply system further includes a power recovery fan fluidly connected to the workshop's exhaust system. The power recovery fan is driven by the induced draft fan and is used to drive the induced draft fan to operate under the influence of the exhaust gas discharged from the exhaust system.

[0011] In an optional embodiment, the workshop air supply system further includes a dehumidification device, which is installed in the air supply duct and is used to dehumidify the airflow passing through it.

[0026] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example Please see Figure 1 , Figure 1 The diagram shown is a structural schematic of the workshop air supply system 100 provided in this embodiment.

[0028] The workshop air supply system 100 provided in this embodiment is used to provide air that meets the temperature and humidity requirements of the workshop. It includes an air supply duct 110 and a workshop air conditioner 120. The air supply duct 110 has an air inlet 111 that is connected to the atmosphere and an air outlet 112 that is connected to the air inlet of the workshop air conditioner 120. The air supply duct 110 is used to draw in external air through the air inlet 111 and then deliver it to the workshop air conditioner 120 through the air outlet 112. The air outlet of the workshop air conditioner 120 is connected to the internal space of the workshop. The air supply duct 110 includes an underground culvert section 113, which is used for ground source heat exchange of the airflow.

[0029] It is understandable that the underground culvert section 113 of the air supply pipeline 110 refers to a section of the air supply pipeline 110 formed by the underground culvert of the workshop. The underground culvert has constant temperature characteristics, and its temperature can be more than 10°C lower than the outside temperature in summer.

[0030] In practical applications, the air supply duct 110 draws in outside air through its air inlet 111 and then delivers it to the workshop air conditioner 120 through its air outlet 112. During this process, the airflow passes through the underground culvert section 113, absorbing the ground source cooling energy of the underground culvert section 113, completing ground source heat exchange, and achieving a preliminary cooling and dehumidification effect.

[0031] The airflow that has undergone ground source heat exchange in the underground culvert section 113 reaches the workshop air conditioner 120 at a relatively low temperature and humidity. The load on the workshop air conditioner 120 is reduced. After further precise adjustment of the temperature and humidity of the airflow, it can be input into the workshop.

[0032] As can be seen, compared with the traditional refrigeration system configured in workshops, the workshop air supply system 100 provided in this embodiment utilizes the space of the underground culvert and the ground source cooling capacity, which can significantly reduce the energy consumption of the workshop.

[0033] In order to improve the cooling and dehumidification effect of the underground culvert section 113, in this embodiment, a cooling rod 114 is installed in the underground culvert section 113. The cooling rod 114 is inserted into the ground to effectively absorb the cold energy from the deep soil, and the part of the cooling rod 114 inside the underground culvert section 113 is provided with heat exchange fins.

[0034] Specifically, there are multiple cooling rods 114, which are arranged sequentially and at intervals along the underground culvert section 113. To prevent the cooling rods 114 from causing excessive obstruction to the airflow within the underground culvert section 113, in this embodiment, the plane of the heat exchange fins is perpendicular to the cross-section of the underground culvert section 113. In other words, the airflow direction in the underground culvert section 113 is approximately parallel to the surface of the heat exchange fins.

[0035] In fact, the air supply duct 110 in this embodiment also includes an air duct section 116, with the air inlet end 111 located at one end of the underground culvert section 113, one end of the air duct section 116 connected to the other end of the underground culvert section 113, and the air outlet end 112 located at the other end of the air duct section 116.

[0036] That is, one end of the underground culvert section 113 is connected to the atmospheric environment, and the end of the duct section 116 away from the underground culvert section 113 is connected to the air inlet of the workshop air conditioner 120. In order to prevent dust, insects and other objects in the environment from entering the air supply duct 110, in this embodiment, a filter screen 115 is also provided at the air inlet end 111 of the air supply duct 110.

[0037] The workshop air supply system 100 provided in this embodiment also includes an induced draft fan 130, which is installed on the duct section 116 of the air supply pipeline 110 and is used to drive the airflow in the air supply pipeline 110 to flow from the air inlet 111 to the air outlet 112.

[0038] When the induced draft fan 130 is running, a negative pressure is formed on the air intake side of the induced draft fan 130, which causes the underground culvert section 113 to draw in outside air, and after ground source heat exchange, it flows into the air duct section 116. The airflow flowing into the air duct section 116 is in a relatively low temperature and low humidity state, and the airflow flows along the air duct section 116, passes through the induced draft fan 130, and flows into the workshop air conditioner 120.

[0039] In practical applications, the equipment in the workshop will continuously generate a large amount of waste heat. Generally, the high-temperature waste gas in the workshop will be discharged to the outside atmosphere through the exhaust system, resulting in a waste of exhaust kinetic energy and heat.

[0040] To address this issue and utilize the kinetic energy of workshop exhaust ventilation to further reduce energy consumption, the workshop air supply system 100 provided in this embodiment also includes a power recovery fan 140 fluidly connected to the workshop's exhaust system. The power recovery fan 140 is driven by an induced draft fan 130 and is used to drive the induced draft fan 130 to operate under the influence of exhaust gas discharged from the exhaust system.

[0041] Specifically, the exhaust gas from the workshop's ventilation system is blown towards the power recovery fan 140, driving it to rotate. This, in turn, drives the induced draft fan 130, which in turn drives the airflow in the air supply duct 110. Therefore, the workshop air supply system 100 provided in this embodiment also utilizes the kinetic energy of the workshop's exhaust ventilation, eliminating the need for a motor in the induced draft fan 130 and further reducing energy consumption.

[0042] Considering that the humidity of the air is still high after passing through the underground culvert section 113, in order to further reduce the load on the workshop air conditioner 120, the workshop air supply system 100 provided in this embodiment also includes a dehumidification device 150. The dehumidification device 150 is installed in the air duct section 116 of the air supply pipeline 110 and is used to dehumidify the airflow.

[0043] Before the airflow in the air supply duct 110 reaches the workshop air conditioner 120, the underground culvert section 113 and the dehumidification device 150 dehumidify the airflow twice in sequence, ensuring that the airflow can reach the workshop air conditioner 120 with lower humidity, thereby significantly reducing the load on the workshop air conditioner 120.

[0044] In order to utilize the heat from the workshop exhaust to further reduce energy consumption, in this embodiment, the dehumidifier 150 is fluidly connected to the workshop's exhaust system and is used to dry and regenerate under the heating effect of the exhaust gas emitted from the exhaust system.

[0045] The dehumidification device 150 can specifically be a rotary dehumidification structure, having two rotary wheels disposed on opposite sides of the outside of the duct section 116, and a moisture-absorbing net fitted between the two rotary wheels and passing through the duct section 116. The two rotary wheels are fluidly connected to the workshop exhaust system. During the rotation of the two rotary wheels, the moisture-absorbing net, which is saturated with moisture, is heated and dried by the exhaust gas blown out by the exhaust system at the two rotary wheels, thus achieving regeneration. The regenerated net then enters the duct section 116 in a dry state to absorb moisture from the airflow again.

[0046] As can be seen, the workshop air supply system 100 provided in this embodiment also realizes the utilization of workshop waste heat, eliminating the need for additional heating devices to heat and regenerate the dehumidification device 150, and further reducing energy consumption.

[0047] In this embodiment, the workshop air supply system 100, in practical applications, allows warm, humid outside air to enter the underground culvert section 113 through the air inlet 111 during summer. During this process, the filter 115 installed at the air inlet 111 prevents impurities from entering the airflow. After entering the underground culvert section 113, the airflow exchanges heat with the walls of the underground culvert section 113 and the cooling rods 114, absorbing ground-source cooling. In practical applications, depending on the structure of the underground culvert, partition walls can be installed within the underground culvert to isolate the waste liquid equipment area of ​​the workshop, forming an ideal airflow path and improving the cooling and dehumidification effect.

[0048] Taking the underground culvert section 113 with a length of 440m and a cross-sectional area of ​​9㎡ as an example, when the outside air temperature is greater than 35℃ and the airflow velocity in the underground culvert section 113 is 5m / s, after the airflow passes through the underground culvert section 113 for preliminary cooling and dehumidification, its temperature can be reduced by 5℃ to 11℃, the relative humidity reaches saturation, and the absolute humidity is reduced by more than 0.0114kg / kg (dry air).

[0049] After the airflow from the underground culvert section 113 enters the duct section 116, it undergoes secondary dehumidification at the dehumidification device 150, and then passes through the induced draft fan 130 into the workshop air conditioner 120. After further precise temperature and humidity adjustment by the workshop air conditioner 120, it flows into the workshop at the temperature and humidity required by the process.

[0050] As can be seen, the workshop air supply system 100 provided in this embodiment utilizes the underground culvert as a cooling and dehumidification channel for fresh air in the workshop, realizing the utilization of the underground culvert space and ground-source cooling capacity. Furthermore, the workshop air supply system 100 converts the kinetic energy of the workshop exhaust air into the power to drive the airflow through the air supply duct 110, achieving the recovery and utilization of exhaust kinetic energy. In addition, it uses the workshop's waste heat as a regenerative heat source for the dehumidification device 150, achieving the recovery and utilization of workshop waste heat.

[0051] Therefore, the workshop air supply system 100 provided in this embodiment makes full use of the structural characteristics of the underground culvert, exhaust kinetic energy and waste heat resources of the workshop without increasing additional energy consumption, thereby achieving efficient and comprehensive utilization of energy, significantly reducing the overall energy consumption of the workshop, and improving energy utilization efficiency and environmental protection performance.

[0052] In addition, this embodiment also provides a production workshop equipped with the aforementioned workshop gas supply system 100, which can be used to produce solar cells, semiconductors, etc. Benefiting from the beneficial effects of the workshop gas supply system 100, it also features lower production energy consumption and better environmental performance.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
