ミサワ環境技術 List of Products and Services

This system was developed with the support of the "Seed Support Program for Disaster-Affected Businesses" by the National Institute of Advanced Industrial Science and Technology's Fukushima Renewable Energy Institute. The only power-consuming devices are the plate fin cooler and the circulation pump, allowing for significant energy savings compared to existing technologies that utilize air-cooled air conditioners. It is a simple system that circulates water between the indoor plate fin cooler and the ground heat exchanger for cooling, without using a heat pump. 【Features】 ■ Cools the waste heat from electronic devices installed in data centers and server rooms using ground heat ■ Circulates water between the indoor plate fin cooler and the ground heat exchanger for cooling ■ The only power-consuming devices are the plate fin cooler and the circulation pump ■ Allows for significant energy savings compared to existing technologies that utilize air-cooled air conditioners *For more details, please refer to the PDF document or feel free to contact us.

We have introduced the "Geothermal Heat Pump" that our company handles to the Marugame City Hall. This product embeds a "geothermal heat exchanger" underground, allowing for heat exchange by receiving and returning heat from the ground using a "heat pump." Compared to air conditioners that exchange heat with air, the temperature variation is smaller, which increases the efficiency of the "heat pump" and reduces power consumption. 【Benefits of Geothermal Heat Pumps】 ■ Environmentally friendly - Effective in suppressing the heat island phenomenon and preventing global warming. ■ CO2 reduction - Expected to reduce CO2 emissions by 19.14 tons annually, a 30% reduction compared to air-source systems. ■ Reduction in electricity usage - Expected to reduce electricity consumption by 33,056 kWh annually, a 30% reduction compared to air-source systems. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case where our "Geothermal Heat Pump" was implemented at Big Roof Takizawa. Takizawa City sometimes experiences harsh cold weather comparable to that of Hokkaido. By utilizing geothermal heat, which maintains a constant temperature, the indoor environment is always kept at a comfortable temperature. Additionally, in the event of a disaster, the facility can be converted to function as an evacuation center, and stable temperature supply is ensured during such times. **Benefits of Geothermal Heat Pumps** - Energy-saving: More efficient than air as a heat source - Low CO2 emissions: Effective in preventing global warming due to reduced CO2 output - Heat island suppression effect: Does not discharge cooling exhaust to the outside air *For more details, please refer to the PDF document or feel free to contact us.*

We installed our "Ground Source Cooling System" at the Aohata Co., Ltd. jam factory located in Takehara City, Hiroshima Prefecture. This system cools the water used in the factory's production line cooling systems by passing it through pipes buried underground. Since it can stably dissipate heat in the ground, where temperature changes are minimal, it efficiently lowers the temperature of the cooling water, leading to various benefits in terms of cost and environmental impact. [Case Overview] ■ Building Floors: Single-story ■ Building Structure: Steel ■ Heat Source Purpose: Process Cooling ■ Ground Heat System: Ground Heat Exchanger, 100m deep × 37 units (Double U-tube) *For more details, please refer to the PDF document or feel free to contact us.
