Mitsubishi Electric City Multi Hot Water Module
Mitsubishi Electric VRF Water Heating Units are the latest technological breakthrough from the Mitsubishi Electric City Multi outdoor Unit Range, with the ability to heat water more efficiently than ever before. The PWFY-P100VM-E-BU indoor module can be installed in conjunction with standard City Multi VRF air conditioning indoor units, creating huge potential for heat recovery.
Available in one size: PWFY-P100VM-E-BU (12.5kW heating) which is modular to allow creation of larger solutions. Sanitary water heating has suitable applications in: hotels and motels, apartments, commercial kitchens and laundries, office buildings, food processing industry, heat recovery from air conditioning systems into sanitary water storage, and direct sanitary water heating is also possible.
The BU Series water heating unit is perfect for sanitary hot water, with excellent heat recovery possibilities. It houses a second compressor running on R134A refrigerant creating a cascade circuit between two plate heat exchangers. with the ability to sense flow or return water temperature with a dip-switch setting, these units can only be connected to City Multi R2 Series outdoor units. The smallest stand alone VRF hot water system is therefore 25kW of heating. Heat recovery from air conditioning systems into sanitary water storage and direct sanitary water heating is also possible. Heat recovery technology taps into and utilises otherwise wasted heat energy, extracted from areas of a building that require cooling, providing heating for hot water. Recovering the heat in this manner maximises the efficiency of the system all year round, therefore increasing energy savings and substantially lowering running costs. Inputs: ON/OFF, Set Temp, Pump Interface. Outputs: ON/OFF, Error, Defrost.
