Example of implementation 3 (combination of cooling/heating system and snow melting system)

Among the example of implementation of Geothermal Heat Pump system produced by Mitsubishi Materials Techno, the followings are examples of combined system of cooling/heating and snow-melting.

(1) Nishimeya-mura, Nakatsugaru-gun, Aomori

A combination system of cooling/heating system and snow-melting system
in a new office building of Shinfukufune Co., Ltd.

We installed geothermal heat pump systems for air conditioning of the new office built in 2002 and for snow-melting on sidewalk and road in front of the office. The two heat pumps were installed for air conditioning system and snow melting system, and ground heat exchanger was used for both systems. The efficiency of this system was considered to be very high.

(2) Hirosaki-shi, Aomori

Cooling/heating in “Machinaka Information Center”
and a snow-melting of one section of sidewalk in Yamamichi-cho

We installed a geothermal heat pump system for a part of air conditioning system and snow-melting on sidewalk in "Machinaka Information Center" in Hirosaki-shi. The two heat pumps were installed and the ground heat exchanger was used for both pumps. The running cost was considered to be very economical.

Other examples of implementation

(1) Senboku-shi, Akita (old Tazawako-machi)

Hot water heating system using abandoned geothermal well

By injecting stream water into abandoned well of no more spouting of hot steam, we built a hot water generating system by heat exchanging in the well. We estimated economical efficiency by simulating heat exchange rate from temperature data of the well.
