Can the chemical filter modification be done together with the energy-saving modification of the air conditioning box?

Chemical filtration retrofits can be evaluated together with air conditioning box energy-saving retrofits, but gas targets, ventilation needs, fans and controls need to be checked under the same operating conditions. Saving energy cannot come at the expense of reducing necessary filtration effectiveness or fresh air requirements. When two transformations are stacked together, the most likely problem is that each has its own account, and in the end the system operation points are inconsistent.

The two transformations change the same set of operating parameters

Adding a new chemical filter section will change the resistance, changing the fan or adjusting the control will change the air volume, and the change in air volume will in turn affect the actual flux and gas effect of the filter section. These three are intertwined and cannot be accounted for separately. When comparing energy savings, the air volume, resistance and target gas effect after modification should be determined first, and then the input power and annual electricity consumption should be calculated. If you first calculate the energy savings by reducing the air volume, and then go back and find that the gas effect is not up to standard and increase the air volume again, the energy saving figures will be meaningless. When Aili Industrial is supporting the chemical filtration section, it can provide resistance data based on the actual air volume and media configuration, so that it can be easily checked with the fan operating point on the same table.

Energy saving cannot be saved from the filtering effect

The resistance of the chemical filtration section can indeed be reduced by expanding the effective area and optimizing the pleat structure, but this is different from reducing the number of media layers or shortening the filter element. The former is to improve flow conditions while maintaining gas targets, while the latter may directly weaken capacity and efficiency. If there is a proposal to 'reduce filter material to reduce resistance' in the modification plan, you should first check whether the target gas and outlet requirements can still be met. Regarding the impact of expanding the filtration area on energy consumption, please refer toCan expanding chemical filtration area reduce long-term energy consumption? . Aili Industrial can compare the resistance performance of different filter section structures based on air volume and space conditions, and evaluate the resistance reduction and protection effects together.

The fan and control should be rechecked according to the new operating point

Energy-saving renovation of air-conditioning boxes often involves fan replacement or frequency conversion speed adjustment, and the addition of chemical filter sections will change the operating point on the original fan curve. What needs to be checked is: whether the fan can provide sufficient static pressure at the target air volume, whether the speed adjustment range covers normal and peak operating conditions, and whether the control logic includes the filter section pressure difference in monitoring. When comparing old and new fans only based on nameplate power, it is easy to overlook the operating point offset. Regarding the residual pressure check after adding filter sections to the MAU, please refer toHow to check the residual pressure outside the machine after MAU adds a chemical filtration section? . Aili Industrial's manufacturing and supporting system covers the independent R&D, production and control systems of motors and fans. It can align filter section resistance, fan selection and control interfaces in the same package, reducing information omissions when connecting across manufacturers.

The boundaries of transformation and acceptance must be explained clearly at one time

When two transformations are carried out at the same time, the construction interface, shutdown arrangements and acceptance objects are easily confused. It should be clear which ones belong to filtration modifications and which ones belong to energy-saving modifications, and what are their respective acceptance indicators. Gas effects, particle requirements, air volume balance and input power need to be tested separately, and one of them cannot be qualified to replace all acceptances. Keep the air volume, power and gas data of the original system as a baseline before the transformation. Only by comparing under the same working conditions after the transformation can the conclusion be well-founded. Regarding the issue of fan speed setting after modification, please refer toHow to set the upper limit of fan speed after chemical filtration transformation?。

Aili industrial supporting equipment

For air-conditioning boxes that undergo chemical filtration and energy-saving renovation projects at the same time, we generally recommend that customers put the two items into one operating condition table for verification, rather than inviting bids in two separate projects. Aili Industry can provide selection packages for box-type, flat-plate and V-type chemical filtration products. For box-type MAU packages, please refer toMAU box chemical filter page, product series can be viewedChemical filter product range . The manufacturing end covers independent R&D and production of motors and fans, control systems, sheet metal and complete machine assembly. Filter section resistance changes, fan operating points and control logic can be confirmed in the same package. Non-standard structures can also be customized according to the box space. If the original system involves replacing the imported filter element, it can be adapted according to the interface size and media requirements. The specific gas effect, resistance performance and energy saving data still need to be verified based on the corresponding configuration data and on-site working conditions. The actual results are subject to on-site leak detection and gas detection results.

Related questions and answers

Is it okay to do chemical filtration modification first and then energy-saving modification?
Yes, but complete operating data should be retained between two modifications. The second modification must recheck the fan operating point based on the actual resistance after the first modification, and the parameters before the modification cannot be used.

After energy-saving renovation reduces the air volume, will the chemical filtration effect be affected?
Reducing the air volume will change the filter section flux and room air flow organization, which may affect gas control and cleanliness. The outlet gas and area status should be verified under the target air volume before confirming the energy saving plan.

Can Aili Industry participate in the overall verification of air conditioning box modification?
It can be combined with the filter section resistance, fan selection and control system to provide supporting verification, and the filtration and air supply conditions can be evaluated at the same operating point. The specific plan needs to be confirmed based on on-site working conditions and product data.
