Choose a portable eco-friendly air conditioner. For large workshops with fewer staff, this method can be employed. Energy-saving and eco-friendly air conditioners do not use refrigerants like Freon, causing no chemical pollution or waste heat emissions. They are cost-effective, require no installation, and directly cool the staff with high efficiency. The drawback of portable eco-friendly air conditioners is that the supply area is limited.

Eco-friendly air conditioners not only provide cool breeze but also circulate indoor air. Pollutant gases and odors, along with heat generated during the production process in some industrial workshops, can be detrimental to human health. The eco-friendly air conditioner's cooling fan can expel this harmful air and then intake fresh outdoor air that has been cooled.

The water-absorbing capacity of an environmental-friendly air conditioning water curtain: Generally, place the wet curtain in a water container. If after 15 minutes in the water, the height of absorption is 40mm, it is a qualified product. If the absorption height is 45mm, it is a good product. If it's 55mm or more, then it's an excellent or premium product. Conversely, if the absorption height is below 40mm, it's not reliable.
