• Temperature and Humidity Control

Q: What happens if a problem occurs due to a malfunction of ESCO-ONE? A: If we visit your location and determine that the cause is related to ESCO-ONE, we will compensate for the damages through the insurance we are enrolled in. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: What happens if the ESCO-ONE malfunctions? A: It will revert to the pre-installation state, and there will be no adverse effects on the compressor or other components. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: What is the installation work for ESCO-ONE like? A: ESCO-ONE is compact, about the size of a tissue paper box, and is installed on each outdoor unit (or on the indoor unit if the compressor is located indoors). The power to each air conditioner is turned off in sequence, but there is no power outage for lighting or other systems, so it can usually be done even during business hours. Installing about 30 units can be completed in three days. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: How can we understand the energy-saving effects of ESCO-ONE? A: By recording data on power consumption, control power, operating hours, and energy usage for up to 540 days within ESCO-ONE, we have successfully achieved "visualization" of energy savings. This allows us to support energy conservation law measures and the preparation of reports. Of course, it is often evident from the utility company's bill as well. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: Isn't energy saving by ESCO-ONE the same as raising the temperature setting for air conditioning? A: Essentially, it is the same in that it reduces the operation of the compressor. Raising the temperature setting means enduring a hot room temperature for a long time, whereas the moderate intermittent operation by ESCO-ONE can maintain a comfortable room temperature. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: By controlling with ESCO-ONE, the indoor temperature rises, and to compensate for that, it operates more, resulting in not being energy-efficient, right? A: The air conditioner's temperature thermostat actually has an error of ±1.5℃, and it will not initiate a follow-up operation to lower the room temperature for a temperature rise within 1℃. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: Won't the indoor temperature rise and become hot when controlled by ESCO-ONE? A: It cannot be said definitively as it depends on the site conditions, building materials, operational methods, equipment capacity, and heat load, but generally, a slight increase in temperature does occur. Measured changes in room temperature show that the temperature rise is within 1°C, and during the compressor's off periods, the airflow is maintained, utilizing the residual heat from the air conditioning indoor unit and refrigerant, so there is hardly any noticeable change in comfort. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: Does controlling with ESCO-ONE affect the lifespan of air conditioners and refrigeration units? A: According to the manufacturer's response, starting and stopping the compressor up to 6 times per hour is not a problem, and controlling it 1 to 2 times within 30 minutes is certainly not frequent control. Therefore, it has little impact on the typical lifespan of air conditioners and refrigeration units, which is 10 to 20 years. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: Are there any models that cannot be controlled by ESCO-ONE? A: There are a variety of models from various manufacturers available on the market, but about 5% of them are not suitable for control. Recently, there has been an increase in models that come with terminals for control in advance to facilitate control. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: What kind of control method is it? A: We install one ESCO-ONE unit for each air conditioner and refrigeration compressor, setting the control rate according to individual usage conditions. The compressor is stopped once or twice during a 30-minute demand unit, reducing both power consumption and demand values simultaneously. During the compressor's stop period, we maintain airflow and utilize the residual heat from the air conditioning indoor unit and refrigerant to minimize temperature changes indoors. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: Is one ESCO-ONE needed for each outdoor unit? A: Generally, one is needed for each outdoor unit, but in the case of multi-type outdoor units, there are models that can control multiple outdoor units with one unit, which may improve cost-effectiveness. *For more details, please refer to the related links or feel free to contact us.

• Temperature and Humidity Control

Q: How would you describe ESCO-ONE in one word? A: It is a system that monitors the operating status of air conditioning and refrigeration compressors, controls their operation at the appropriate timing, and reduces power consumption and demand values without compromising indoor comfort. *For more details, please refer to the related links or feel free to contact us.*

• Temperature and Humidity Control

Here is a case study of the introduction of "ESCO-ONE" at a pachinko parlor. A few years ago, during peak times, demand exceeded 500 kW, leading to a notification from the power company to change to a negotiated contract (contract demand over 500 kW), resulting in increased electricity costs and difficulties. By implementing this product, annual electricity costs were reduced by 2,200,000 yen, and the contract demand decreased from 547 kW to 482 kW, successfully transitioning from a negotiated contract to a contract based on actual usage. [Case Overview] ■Challenges - Outside of peak periods, the usage situation was around a contract demand of 400 kW, so we were looking for a way to stabilize demand below 500 kW and escape from the negotiated contract. ■Results - With the introduction of ESCO-ONE, demand has been stably kept below 500 kW without causing environmental changes.
