Frequency conversion waste heat generator set

The utility model discloses a frequency conversion waste heat generating set which comprises an evaporator, an expansion machine, a generator, a condenser and a refrigerant pump, the refrigerant sideof the evaporator, the expansion machine and the refrigerant side of the condenser are connected with the refrigerant pump in a closed loop mode, a rotor of the expansion machine is connected with a rotor of the generator, and the generator is a frequency conversion generator. The variable-frequency generator is adopted, the generating frequency is irrelevant to the rotating speed of the unit andcan be continuously adjusted, so that the generating frequency can be kept consistent with the frequency of mains supply, when the load changes, the generator does not need to be separated from the mains supply, and the unit is prevented from being damaged by internal heating of the generator during separation. 本实用新型公开了一种变频余热发电机组，其包括蒸发器、膨胀机、发电机、冷凝器和冷媒泵，蒸发器的冷媒侧、膨胀机、冷凝器的冷媒侧和冷媒泵闭环连接，膨胀机的转子与发电机的转子连接，发电机为变频发电机。由于本实用新型采用变频发电机，发电
