A vapor supply device includes a sunlight-condensing heat collection unit which condenses sunlight and collects heat to obtain thermal energy, a heat-storage and heat-exchange unit which heats a heat-storage agent stored therein using the thermal energy obtained in the sunlight-condensing heat collection unit and stores thermal energy in the heat-storage agent, and heats a supply medium using the thermal energy stored in the heat-storage agent, and a vapor supply unit which supplies a vapor of the supply medium obtained by heating the supply medium in the heat-storage and heat-exchange unit.

System and process for producing steam in a steam-hydrocarbon reforming facility where oxygen is removed from demineralized water using a membrane degasifier. The membrane degasifier operates at a lower temperature compared to a deaerator, which is the conventional technology for removing oxygen.

The invention relates to a method and apparatus for low temperature waste heat utilization. In the scope of the hot water plant (HWP) there are few low temperature sources, which cannot be used by heat consumer (HC) directly. The method and apparatus for hot water power plant (HWP) waste heat recovery comprises at least one, preferably condensing type heat exchanger (HE), which collects the waste heat for water source high temperature heat pump (HP) employment, wherein a low temperature heat is upgraded to a high temperature heat, hence heat pump (HP) hot water outlet is fed to the boiler in a return line or in a supply line of hot water plant (HWP), wherein the thermal energy balance adjustment of generated heat is executed by adapting the power of said heat pump (HP) and/or by adapting the power of said furnace and/or by adapting the mass flow of the primary heat transfer medium in at least one open loop heating network and/or in at least one closed loop heating circuit in the scope of heat distribution network.

The systems and methods of this disclosure control the flow rate of conditioned fluid at thermal distribution devices and at a conditioned fluid source that supplies conditioned fluid to the thermal distribution devices. The systems include multiple thermal distribution devices disposed throughout multiple rooms of a building, a fluid flow control device in fluid communication with each of the thermal distribution devices, multiple sensors disposed on each of the thermal distribution devices, a room temperature sensor disposed in each of the rooms, a first controller coupled to each of the fluid flow control devices, and a second controller coupled to a source of conditioned fluid. The first controllers control respective fluid flow control devices based on the measurement data obtained from the sensors and the room temperature sensors and a second controller controls the conditioned fluid source based on the demand for conditioned fluid by the thermal distribution devices.
