1, natural fluorine and groundwater are two combined supply systems, which are a combined system of central air conditioning and floor heating. As the name implies, "natural fluorine groundwater" is a central air conditioner with fluorine in the air conditioner and water in the floor heating. It is a system that has been transformed and put into the dual-supply product market again, mostly Japanese, but both Hitachi and York have it, because both Hitachi and York belong to johnson controls Group and have a great relationship. Legend has it that technology is shared.
2. "Natural fluorine and groundwater" combined supply system has cooling and heating functions. More importantly, it has two independent systems, fluorine and water, which can be switched freely through valve elements. During indoor heating, the two systems are turned on at the same time to heat the room, so that the room temperature can reach the rated value.
