Groundwater air conditioning [AG-DCS-PR stainless steel exterior pad/radiator combination] has been certified as equipment eligible for energy conservation subsidies.

AQUA EASTER Co., Ltd. (Head office: Omiya-ku, Saitama-shi, Saitama, CEO: Futoshi Kimura)'s renewable energy air conditioner/radiator combination model [AG-DCS-PR] has been certified as an advanced facility/system device under the FY2023 supplementary budget: Energy Saving Investment Promotion Support Subsidy (General Incorporated Association Environmental Co-Creation Initiative).

Three benefits of installing our air conditioning

①Product Overview

This equipment uses groundwater, which is stable at 15-17℃ throughout the year, as its heat source. Low-temperature groundwater is dripped onto a special pad and passed through a dedicated radiator to directly cool the air, achieving highly efficient cooling. Since only the power unit fan and water supply pump are operated, power consumption is less than 1/10 of that of an air conditioner, and significant energy savings can be expected. Even if there is no groundwater, it is possible to reduce power consumption to 1/5 of that of an air conditioner by using a small chiller. The combined radiator specification also provides a dehumidifying effect.

②How groundwater utilization leads to energy savings

  The air inside the room is cooled by pumping stable, low-temperature groundwater (15-17°C year-round) and passing it through a heat exchanger. The air inside the room drops to a comfortable temperature of about 23°C, down to 6-7°C above the groundwater.

Because of how this groundwater air conditioner works, the only electricity consumed is that needed to run the fan and pump, which results in a significant reduction in electricity bills compared to air conditioners.

3) Secondary use of groundwater, which also contributes to the SDGs

The used groundwater can be effectively used as raw water for boilers, general purpose water for toilets, watering roofs, etc. We have received many inquiries about this air conditioning system as one that contributes to the SDGs, from the perspective of utilizing natural energy and being able to reuse groundwater after use.

By using a disinfectant used in tap water and a world-patented catalytic filter, the water quality that is a concern when using natural groundwater is improved. There is no need to worry about mold that occurs with normal evaporation methods, so it can also be introduced in factories that handle food.

④It can also be used as a heater in winter

   Groundwater air conditioning systems can be used not only in the summer. They can also be used for heating in the winter. Although a separate auxiliary heat source is required, in the case of factories, waste heat (from compressors, boilers, machinery, etc.) can be used, which helps to reduce costs and electricity bills throughout the year.
