Ventilation device

The invention discloses a ventilation device, which aims to solve the problem that the conventional ventilation device does not have an air adjusting function. The device comprises a pedestal, a high-speed air blower and an annular ejector, wherein the high-speed air blower is arranged at the bottom of the pedestal; the annular ejector is arranged at an air outlet of the high-speed air blower and is fixed on the pedestal; and the air inlet or the air outlet of the high-speed air blower is provided with a vapor generator which is fixed on the pedestal for producing water vapor. In the ventilation device, the water vapor is produced through the vapor generator and is ejected through an atomization nozzle at a high speed to produce fog of smaller granularity, so that a hot air flow can more easily absorb the latent heat of vaporization, and the ventilation device has a humidification effect and a heat absorption and temperature reduction effect on a large amount of hot air sucked by the annular nozzle, and brings comfortable cool air similar to air on the shore of a lake or a sea to the surrounding environment. In the ventilation device, an external circulating device is not required to be mounted, so the cost is low; the space is not required to be closed, so that air convection is guaranteed; and the ventilation device is more energy-saving in the same temperature reduction range compared with a fan and an air conditioner, and can be used conveniently and safely.

Technique for controlling DCSS condensate levels in a Kalina cycle power generation system

A method of operating a power generation system is provided. The system includes) a turbine, a regenerative heat exchanger, a vapor generator and a distiller/condenser having multiple condensing elements. The turbine expands a vaporized multicomponent working fluid to produce power. The regenerative heat exchanger transfers heat from a lean hot multicomponent working fluid having a relatively low concentration of a component of the multicomponent working fluid to a rich cool multicomponent working fluid having a relatively high concentration of the component to thereby cool the lean hot multicomponent working fluid. The vapor generator vaporizes the cooled multicomponent working fluid to form the vaporized multicomponent working fluid. The multiple condensing elements of the distiller/condenser condense the expanded multicomponent working fluid to form the lean hot multicomponent working fluid. To operate the system, a first portion of the expanded multicomponent working fluid is condensed in a first of the multiple condensing elements. A second portion of the expanded multicomponent working fluid is condensed in a second of the multiple condensing elements to form the lean hot multicomponent working fluid. The flow of the condensed first portion of expanded multicomponent working fluid from the first condensing element is regulated to regulate the amount of the condensed second portion of expanded multicomponent working fluid in the second condensing element.

Vapor temperature control in a kalina cycle power generation system

A method of operating a Kalina cycle power generation system, includes directing a stream of superheated binary working fluid to a turbine where it is expanded to produce power. A first portion of the expanded binary working fluid is directed to a distiller/condenser where it is transformed into a first concentration binary working fluid, having a first concentration of a component of the binary working fluid, and a second concentration binary working fluid, having a second concentration of the component. At least the first concentration binary working fluid is directed to a regenerative heat exchanger. A second portion of the expanded binary working fluid is also directed to the regenerative heat exchanger. The first concentration binary working fluid is transformed into a vaporized binary working fluid and the second portion of expanded binary working fluid is transformed into a feed binary working fluid in the regenerative heat exchanger. The feed binary working fluid is directed to a vapor generator where it is vaporized. The second concentration binary working fluid is combined with the vaporized feed binary fluid to form the superheated binary working fluid. The flow of binary working fluid within the distiller/condenser is actively regulated to regulate the temperature of the superheated binary working fluid.
