Abstract: An electrically driven construction machine is provided in which, in a case where a plurality of electrically driven construction machines operate simultaneously, it is possible to avoid exceeding the allowable electric power that can be output by the electric power receiving facility of a commercial electric power supply. A controller computes an own demanded power Pd1 for driving the plurality of hydraulic actuators, on the basis of operation signals of the operation devices, computes an allowable power as a power limit value usable by the electric motor on the basis of the own demanded power, the demanded powers of the other electrically driven construction machines received through the communication device, and an allowable electric power of the electric power receiving facility of the commercial electric power supply, and controls the electric motor such that a power consumption of the electric motor does not exceed the allowable power.

Abstract: A method including carrying out adiabatic cooling and evaporation operation of a coolant in a crystallizer (20) for a mixture solution of a target organic compound containing the coolant; taking out crystal slurry produced by the operation from the crystallizer (20); pressurizing evaporated vapor to a pressure higher than the operation pressure in the crystallizer (20) by a compressor (30) and then introducing the vapor to an absorption condenser (10); cooling for condensation the mixture solution of organic compound and the evaporated vapor that has been pressurized while allowing them to contact each other in the absorption condenser (10); introducing the crystal slurry taken out of the crystallizer (20) to a purification means (70) for purification of the crystal; and introducing a clarified liquid in the purification means (70) to at least one of the crystallizer (20) and the absorption condenser (10).
