It seems there may be some confusion regarding the water consumption of your portable air conditioner, as typical portable air conditioners do not consume water in the cooling process. Instead, they use refrigerant to cool the air.
However, there is a possibility that your Tornado To Go 14 has an additional feature called a dehumidifier mode. Some portable air conditioners have a built-in dehumidifier function that can remove excess moisture from the air. In dehumidifier mode, the appliance collects moisture from the air, which can result in the accumulation of water.
If your air conditioner has a dehumidifier mode, it will have a separate water collection tank or a drainage system to handle the collected water. It's important to regularly empty the water tank or ensure that the unit is properly connected to a drain if it has a continuous drainage option.
However, it's unusual for a portable air conditioner's dehumidifier mode to consume 2 liters of water per hour. It would be advisable to consult the user manual or contact the manufacturer directly to clarify the water consumption specifications for your specific model.
If your portable air conditioner is not equipped with a dehumidifier mode and it's still consuming a significant amount of water, it may indicate a malfunction or a potential issue with the unit. In such cases, it's best to contact the manufacturer's customer support or a professional technician to diagnose and resolve the problem.
