Background technique
Ammonia can be traced back to before and after 1850 as refrigerant.But since it is with toxicity and in the dense of space accumulation
Degree has potential explosion danger when reaching certain value, so that its application when using as refrigerant is restricted,
It is mainly used in the refrigeration machine of freezer and the cold source of air conditioning of some industrial buildings at present as refrigerant.But in recent years,
Because it is found that CFC class and HCFC class refrigerant are to the destruction of the ozone layer in atmosphere and can generate the rings such as greenhouse effects
Border problem, occurs that CFC class refrigerant disables completely and the gradually limitation of HCFC class refrigerant is using problem.Therefore, ammonia refrigeration
The security performance of agent obtains the concern of people again.In recent years, it is eaten using the freeze-drying of vacuum freeze drying (FD) technology preparation
Product remain the color, smell, taste, shape of product and the nutritional ingredient of ecosystem food, this based food are increasingly liked by people,
Handling refrigeration application in FD frozen dried food using ammoniacal liquor is that the following food service industry is urgently paid attention to and a direction of Innovation Input.
Utility model content
The purpose of this utility model is to provide a kind of ammoniacal liquors to handle refrigeration equipment, it is intended to solve existing ammoniacal liquor processing refrigeration
Ineffective technical problem.
The utility model adopts the following technical solution: a kind of ammoniacal liquor processing refrigeration equipment, comprising: evaporator, throttle check
Valve, refrigerant heat exchanger, condenser, rectifying column, generator, solution heat exchanger, hydraulic pump, absorber.
