Title:
WARMUP SYSTEM USING RECOVERY OF WASTE HEAT OF CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/110894
Kind Code:
A1
Abstract:
According to the present invention, a warmup system using the recovery of waste heat of a construction machine comprises: an organic Rankine cycle for circulating, in the construction machine having a hydraulic system, a cooling system, and an engine, operating fluid so as to allow the same to successively exchange heat with waste heat or waste energy of the hydraulic system, the cooling system, and the engine; and a turbine to which the operating fluid having circulated through the organic Rankine cycle flows so as to generate mechanical energy for driving the construction machine, wherein if the operating fluid successively exchanging heat with the waste heat or waste energy in operating oil of the hydraulic system, cooling water of the cooling system, and exhaust gas of the engine is not completely evaporated, the operating fluid does not flow toward the turbine and can flow toward the hydraulic system or the cooling system.
