Title:
HEAT-PUMP-TYPE STEAM GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/049663
Kind Code:
A1
Abstract:
A heat-pump-type steam generation device in which, in order to prevent adhesion of scale, heat is absorbed by a refrigerant from heat source water and the heat absorbed by the refrigerant is transmitted to water to be heated to generate steam, wherein the heat-pump-type steam generation device is provided with: a heat pump unit in which the refrigerant is sequentially channeled in a circulating manner through an evaporator, a compressor, a condenser, and an expansion mechanism; a heat source water supply unit for channeling the heat source water through the evaporator; a steam generation unit for channeling the water to be heated, introduced from the exterior, through the condenser to generate steam; and a control unit for performing, when given an operation stop command, a dilution process of increasing the flow amount of the water to be heated introduced from the exterior to the steam generation unit.
