The high pressure steam generator is connected with the condenser through a water supply pump, and the evaporator is connected with the condenser through a throttle valve. The high pressure steam pressure of the utility model is larger than 2MPa, and the thermodynamic coefficient can reach more than 1.5. Compared with a lithium bromide refrigerating unit, the volume and the weight of the utility model can reduce more than 30 percents.
Description
Affiliated technical field
The utility model relates to refrigerating plant, refers in particular to a kind of direct combustion steam ejection refrigeration unit.
Background technology
Existing air conditioner cold water unit adopts compression or absorption refrigeration unit mostly, and compression-type refrigeration is restricted because of the influence of its working medium to atmospheric environment, and there is inadequate natural endowment in the coefficient of performance of absorption refrigeration.The thermodynamic coefficient of lithium bromide refrigerating unit in the market can only reach about 1.2, and volume and weight is big, and difficulty is regulated in operation.
The steam-sprayed refrigeration of (sixties in 20th century) use is lowly superseded substantially because of its thermodynamic coefficient in one's early years, and the low major reason of thermodynamic coefficient is the low-pressure steam (being generally 0.4Mpa) of its use.
Summary of the invention
In order to improve the thermal performance of air conditioner cold water unit, the utility model provides a kind of direct combustion steam ejection refrigeration unit.
The technical scheme that its technical problem that solves the utility model adopts is:
Device comprises evaporimeter, it is characterized in that being provided with high pressure steam generator, and it is linked to each other by injector with evaporimeter, and injector connects condenser.High pressure steam generator links to each other with condenser through feed pump, and evaporimeter links to each other with condenser through choke valve.
With high pressure steam generator the chemical energy of fuel is converted to high steam heat energy, high steam at first expands in injector and forms high vacuum, come the low-pressure steam of flash-pot in order to injection, reach the purpose of refrigeration with the low pressure evaporation conditions of keeping evaporimeter, send into condenser with jetting steam caused after mixing diffusion then, water recovery is a condensed water in condenser, part condensed water is sent into high pressure steam generator by feed pump and is recycled, another part condensed water after choke valve throttling step-down as the moisturizing of evaporimeter.
The high-pressure steam pressure of this unit can be greater than 2MPa, and thermodynamic coefficient can reach more than 1.5, compares with the lithium bromide refrigerating unit, and its volume and weight can dwindle more than 30%.
