Emergency measure! Measures against high temperatures in compressors using groundwater, a renewable energy source!

The heat is so intense the compressor is screaming

The summer of 2018 was indeed a record-breaking hot one. High temperatures that were unimaginable 20 years ago have become the norm, and our common sense regarding air conditioning is also changing.
Aside from the effects on the human body, this heat is actually causing serious damage to production equipment, most notably compressors.
When the equipment was first installed, ventilation alone was enough for the compressor room, but now ventilation alone is no longer enough to expel the heat, and many facilities are recording room temperatures of 40°C or higher. A rise in intake temperature is the biggest enemy of a compressor. If the room temperature exceeds 40°C, not only will the efficiency decrease, but the temperature will exceed the allowable temperature of the equipment, causing an interlock. However, it is nearly impossible to install air conditioners that can handle the enormous amount of ventilation required for a compressor room. This quarter, we have seen a sharp increase in inquiries from customers about this issue.

By using groundwater, a renewable energy source, cooling is possible with very little electricity.

Our groundwater direct cooler, which uses renewable energy, is the ultimate eco-friendly cooling method that cools the air only by exchanging heat between groundwater and air.
When the room temperature is 30°C, the outlet temperature is approximately 2 to 3°C above the groundwater temperature, meaning that it is possible to blow cool air at below 20°C.
The compressor intake air can be cooled directly using a fan-equipped unit, or if there is an exhaust fan in the compressor room, you can simply attach a heat exchanger to the intake port to create a power-free cooler.

Compressor intake air cooling also leads to energy savings

According to the guidelines of the Energy Conservation Center, lowering the compressor intake temperature by 5°C will result in an energy saving effect of approximately 11 TP3T. If this is cooled from 40°C to 25°C, an energy saving effect of more than 51 TP3T will be obtained.
The introduction of a groundwater direct cooler not only ensures stable operation of the equipment, but also saves energy.

Actual cost simulation example

There are two types of groundwater coolers that use renewable energy and can be selected based on cost and conditions.

Our groundwater direct coolers that use renewable energy are available in two types, and you can choose between the two depending on your conditions and costs.
Radiator type has a dehumidifying effect, making it more energy efficient.
Direct heat exchange systems can be operated with a small amount of water, and the cost and delivery time can be kept low. If the groundwater temperature is low enough, there is no need to worry about humidity rising.
We will make optimal suggestions based on your installation conditions.
