REFRIGERATION DEVICE PROVIDED WITH WASTE HEAT USING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a refrigeration device provided with a waste heat using device capable of securing reliability and exerting sufficient performances for both cycles in devices provided with a refrigeration cycle and a Rankine cycle. SOLUTION: The refrigeration device provided with a waste heat using apparatus is mounted on a vehicle and includes the cooling cycle 200 and the Rankine cycle 300. A condenser 220 for the refrigeration cycle and a condenser 340 for the Rankine cycle are arranged at predetermined sections of a vehicle in parallel with a direction of flow of cooling external air. The condenser 220 for the refrigeration cycle is arranged at an external air upstream side of the condenser 340 for the Rankine cycle. When the refrigeration cycle 200 and the Rankine cycle 300 are simultaneously operated, rotation speed of an expander 330 is controlled to keep expander differential pressureΔP greater than a predetermined valueΔPa.
