Positive pressure management and groundwater air conditioning"},"content":{"rendered":"

"Positive pressure management" is used in facilities that require hygienic and clean spaces, such as food factories, pharmaceutical factories, and semiconductor factories. By adjusting the balance of intake and exhaust in the facility to create a state where the intake volume is greater than the exhaust volume, the pressure inside the room will be over 1 atmosphere, and air will be released to the outside. This will prevent dust, bacteria, and other foreign matter from entering from the outside, and is an important concept in the air conditioning design of clean factories and clean rooms.<\/p>\n\n\n\n

However, positive pressure requires the constant introduction of a large amount of outside air. This places a heavy burden on the temperature and humidity control of the air conditioner, and the air that is simply being released must be heated and cooled. In particular, the cooling load caused by positive pressure has been an issue for many clean factories.<\/p>\n\n\n\n

That's where groundwater air conditioners come in handy. They don't use compressors, and instead use the temperature of groundwater to cool large volumes of air with very little power consumption. This means that the outside air introduced for positive pressure management can be cooled at extremely low cost, and they have the potential to be used to cover air conditioning needs.<\/p>\n\n\n\n

Our groundwater air conditioners use our unique multi-panel technology, which allows them to cool with a small amount of groundwater, making it possible to instantly solve the high cooling load caused by positive pressure management. In fact, we have successfully achieved significant reductions in electricity bills in various facilities.<\/p>\n\n\n\n

Positive pressure management is important not only in clean factories, but also in all facilities where virus countermeasures are required. Why not consider groundwater air conditioners as a solution to the cooling load that will continue to increase in the future? We will make optimal proposals for each facility. Even if there is little or no groundwater, it is possible to operate it much more efficiently than normal air conditioning, so please feel free to contact us.<\/p>","protected":false},"excerpt":{"rendered":"
