Installation, Configuration & Operation Manuals

50% of energy consumption in office buildings is related to air conditioning. The FRENIC-HVAC series are inverters for HVAC that have key features, functions and performances that offer the optimal thermal environment for the people working in the building by keeping the energy consumption in various devices such as compressor, condenser water pump and AHU to a minimum. Fuji Electric contributes largely to global environment by realizing carbon dioxide reduction with energy saving by the inverter.

FRENIC-HVAC is designed for various type of environments, such as supply voltage, enclosures. The user gets every key features for HVAC market in one unit, such as EMC filter is equipped as standard feature for all models and DCR is equipped in certain capacity range.

For an air-conditioning heat source system, the quantity of the cooling or heating water fluctuates generally during the seasons or days and nights. Therefore, operations continuing in a water conveyance pressure constant control may lead to high operating pressures on terminals at low operating state. The pump consumes an inefficient electric power for maintaining the high water conveyance pressure.

FRENIC-HVAC inverters can perform an estimated terminal pressure control by linearization function which estimates target pressure from a load flow rate. It is possible to reduce the inefficient pump power consumption and to achieve energy-savings while maintaining comfortable air conditioning.

The cooling tower fan is used to cool the temperature of cooling water by emitting it into the air. The fan speed is adjusted optimally according to the cooling water temperature at the outlet. Moreover, the inverter estimates the wet-bulb temperature automatically to control the fan so that the temperature of cooling water (wet bulb) is interlocked to the air temperature.

The cooling water pump circulates the cooling water to the cooling tower in order to cool the heat generated by the Refrigeration machine. The pump speed is adjusted optimally according to the temperature and flow rate of cooling water. Moreover, the inverter can control the cooling pump so that the difference of the cooling water temperature at between the inlet and outlet is constant.

The chilled water pump circulates the chilled water generated with the Refrigeration machine to the air conditioner and fan coil. The pump speed is adjusted optimally according to the header pressure. Moreover, the pump conveyance pressure can be controlled to the proper value by converting the flow rate signal to the target pressure using the linearization function.

The speed of supply and return fans is adjusted optimally according to the pressure, discharge temperature, room temperature, and others. Moreover, the highest level of carbon dioxide is selected automatically by detecting the level in room to control it to stay within the allowable level.
