Well-Thermal Heat Pump
Well-Thermal Heat Pump effectively takes out heat energy from underground which we can continuously and sustainably utilize without harms on the environment.
What is Special about Our Heat Pump?
- Patents
We have filed patents for several technologies related to Well-Thermal Heat Pump. - Direct Expansion System
Adding to antifreeze system, we can offer direct expansion system. It takes out energy much more efficiently than conventional antifreeze one. In terms of coefficient of performance (COP)*, that of Well-Thermal Heat Pump is 6 on average while that of antifreeze system is approximately 3. It is clear that our direct expansion system is efficient. - Very Unique Multi-Use Type
Common heat pumps usually have a combination of air cooling and water heating functions. Not only these, Well-Thermal Heat Pump is capable of heating room and water at the same time. Furthermore, we can add floor heating.
*Actual value of COP depends on the situations.
Global warming has been one of the most serious environmental issues that human beings face. Among all, reduction of CO2 emission has been discussed globally for long. Our Well-Thermal Heat Pump not only helps solve this problem through reducing environmental loads, but contributes to lessening heat island effect, another environmental problem.
Well-Thermal Heat Pump uses year-round stable temperature of underground, which is the same as the average yearly temperature, for air conditioning and/or heating water. In winter, it obtains heat from underground where temperature is higher than the outside air, meanwhile it supplies cool air and releases heat to underground where temperature is lower than the outside air in summer.
Therefore, you can expect high energy-saving. Since Well-Thermal Heat Pump is powered by electricity instead of fossil fuel, it is possible to reduce CO2 and NOX emissions. Besides, this system alleviates heat island effect as it does not release heat to the air, while air cooled heat pump does.

Merits of Direct Expansion System
- Higher COP
- Less noise
- Simple structure realizes easy, reasonable and short-term construction and maintenance
Sources of Heat
Geothermal Type
A heat exchanger(s) is installed in the ground with antifreeze/ refrigerant circulated within pipes to collect and release heat in the ground.
Groundwater Type
The basic structure is almost the same as that of geothermal type. The difference is that this type needs a well(s) to pump groundwater and takes out heat from it.
Enhancing Quality of Agriculture
We contribute to the improvement of agriculture as well as the global environment by utilizing constancy of underground temperature to our unique systems for agriculture: geothermal and groundwater heat pumps. Needless to say, these systems can be applied not only to agriculture but also to any industry.
Features
- Heat energy of underground has little effect on the natural environment. Underground temperature is constant throughout a year, which enables to provide stable warmth even in the cold latitudes.
- Our system can set the temperature from high to low.
- The conventional “Water to Water” system makes warm air from warm water produced from heat of geothermal or groundwater. Well-Thermal Heat Pump adopts “Water to Air” system that makes warm air directly from geothermal or groundwater heat.
Intended Purposes
- Heating greenhouses during winter
- Night-time cooling and dehumidification during summer
