Optional Parts H.Stars Screw Type Chiller/Heat Pump Unit Heat Recovery The condensing heat of the chiller (usually discharged into the atmosphere by the cooling tower) is recovered and used effectively. For example, a hotel needs to provide both heat (for hot water) and air conditing during the summer. With the heat recovery, the heat absorbed during cooling can be transferred to the building where hot water is needed by heat recovery. In the cooling season, hot water above 50 °C can be provided free by adopting the heat recovery unit. Heat recovery of up to cooling capacity 30% to 100%. H.Stars...

H.Stars Screw Type Chiller/Heat Pump Unit VFD (Variable Frequency Driver) technology VFD is to change the power supply frequency, thus adjusting the load, to reduce power consumption, reduce losses, and extend the life of the equipment. The core of VFD technology is the Variable-frequency Driver. Automatic adjustment of motor operating speed rate by conversion of power supply frequency to make the fixed grid of 50 Hz change to the frequency of of 30-130 Hz. At the same time, the power supply voltage adapts to the range of 142-270V, which solves the problem that the electrical equipment voltage...
