Title:
STEAM GENERATION DEVICE
Document Type and Number:
Japanese Patent JP2023132164
Kind Code:
A
Abstract:
To provide a steam generation device capable of maintaining high cycle performance in a heat pump cycle by adjusting the state of refrigerant at the outlet of a vaporizer.SOLUTION: A steam generation device 1 in the embodiment includes: a heat pump system 5 for circulating a refrigerant in a compressor 10, a radiator 20, a heat exchanger 30, an expansion part 40, a vaporizer 50, and the heat exchanger 30 sequentially to make heat exchange between a low pressure side refrigerant passing through the vaporizer 50 and high pressure side refrigerant passing through the radiator 20 in the heat exchanger 30; a fluid supply pipe 51 for supplying, to the vaporizer 50, a fluid that gives a heat quantity to the refrigerant in the vaporizer 50; and a water supply pipe 21 for supplying water to the radiator 20 to generate steam in the radiator 20 through heat exchange with the refrigerant. The steam generation device 1 adjusts at least one of a degree of opening of the expansion part 40 and a heat exchange quantity in the vaporizer 50 on the basis of a state amount of the refrigerant at an outlet of the vaporizer 50.SELECTED DRAWING: Figure 1
