Outfan be connected, the input of described expansion valve is connected with the input of described temperature-responsive expansion valve, described board-like changes
The outfan of hot device is connected with the input of described gas-liquid separator after being in parallel with the outfan of described temperature-responsive expansion valve,
The outfan of described gas-liquid separator is connected with the input of described compressor, and the outfan of described compressor connects described condensation
After device, the input with described reservoir is connected, with institute after the expansion valve described in outfan one side connection of described reservoir
The input stating plate type heat exchanger is connected, and is on the other hand connected with the input of described temperature-responsive expansion valve；Described
Water tank is circulated with described first water pump and plate type heat exchanger successively by pipeline and is connected, and is respectively mounted having heaters and temperature in water tank
Degree sensor；Described temperature sensor by controller respectively with described compressor, temperature-responsive expansion valve and heater
Electrical connection.
The described military idle call cold regulation supporting for laser instrument and self-protecting device, it is characterised in that: described
Water tank is connected with described second water pump and load cycle successively by pipeline.
This utility model is reload temperature response expansion valve between the input and the input of gas-liquid separator of expansion valve,
Thermic load is big when, temperature-responsive expansion valve opening reduces, and makes unit refrigerating capacity increase；Thermic load is little when, temperature
Degree response expansion valve opening increases, and makes unit refrigerating capacity reduce, and can adapt to thermic load and become on the premise of not start and stop compressor
Change violent loading condition.
The beneficial effects of the utility model:
This utility model fluctuates relatively greatly and to feed flow temperature requirement at short notice for laser instrument and similar thermic load thereof
Higher occasion, by controlling Programmable detection sensor signal, compared with design temperature, according to control algolithm regulation and expansion
The aperture of the temperature-responsive expansion valve that valve is in parallel regulates the refrigerating capacity of refrigeration system, and regulation refrigerating capacity also prevents compressor etc.
Action component frequent starting, meets design objective, extends service life.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
See Fig. 1, a kind of military idle call cold regulation supporting for laser instrument and self-protecting device, include water tank 1,
First and second water pump 2,3 and refrigeration system, refrigeration system includes compressor 4, condenser 5, reservoir 6, expansion valve 7, temperature sound
Answering expansion valve 8, plate type heat exchanger 9 and gas-liquid separator 10, the outfan of plate type heat exchanger 9 is defeated with temperature-responsive expansion valve 8
Going out end to be connected, the input of expansion valve 7 is connected with the input of temperature-responsive expansion valve 8, the outfan of plate type heat exchanger 9 with
The outfan of temperature-responsive expansion valve 8 is connected with the input of gas-liquid separator 10 after being in parallel, the output of gas-liquid separator 10
End is connected with the input of compressor 4, and the outfan of compressor 4 is connected with the input of reservoir 6 after connecting condenser 5,
The outfan of reservoir 6 is connected with the input of plate type heat exchanger 9 after on the one hand connecting expansion valve 7, another aspect and temperature
The input of response expansion valve 8 is connected；Water tank 1 is circulated with the first water pump 2 and plate type heat exchanger 9 successively by pipeline and is connected,
Water tank 1 is respectively mounted having heaters 11 and temperature sensor 12；Temperature sensor 12 by controller respectively with compressor 4,
Temperature-responsive expansion valve 8 and heater 11 electrically connect.
In this utility model, water tank 1 is connected with the second water pump 3 and load 13 circulation successively by pipeline.
Below in conjunction with accompanying drawing, this utility model is further described:
Equipment operationally, first sets a temperature value, and this temperature value is normally close to the standard temperature needed for equipment
Value, the temperature sensor 12 in water tank 1 is by water temperature Real-time Feedback to controller, and controller is according between setting value and measured value
The temperature difference controls the open degree of temperature-responsive expansion valve 8, and the refrigerant flow being flow through plate type heat exchanger 9 by regulation carrys out equipment
Output cold.
This utility model applies also for other occasion, PID can be selected to control according to the required precision that target temperature controls,
Fuzzy control, robust control etc. control technology.
Specific works process is as follows:
As it is shown in figure 1, during start, the water tank temperature that controller measures according to temperature sensor 12 compares choosing with design temperature
Select heater 11 or compressor 4 carrys out the temperature of regulating tank 1 to setting value, and opened in water tank by the first water pump 2
Circulation, realizes the harmony of each point temperature in water tank 1.
After reaching design temperature, equipment starts as laser instrument feed flow, and the now temperature sensor 12 in water tank 1 is still being surveyed
Determining water tank temperature, and be sent to controller, controller monitors water tank temperature and in real time compared with setting value, and the temperature difference is changed
Becoming corresponding control signal to deliver to temperature-responsive expansion valve 8, temperature-responsive expansion valve 8 receives after control signal according to control signal
Regulate the open degree of self, regulate the refrigerant flow flowing through plate type heat exchanger 9.When the temperature difference is less, temperature-responsive expands
The unlatching of valve 8 increases, and makes the cold-producing medium flowing through plate type heat exchanger 9 reduce, it is achieved less refrigerating capacity；When the temperature difference is bigger, temperature
The unlatching of degree response expansion valve 8 reduces, and makes the cold-producing medium flowing through plate type heat exchanger 9 increase, it is achieved bigger refrigerating capacity；And it is warm
The response speed of degree response expansion valve 8 is very fast, can be adjusted to meet laser instrument the most at full capacity from less refrigerating capacity rapidly
The refrigerating capacity of work, thus realize realizing the regulation of refrigerating capacity under the conditions of without action components such as frequent start-stop compressors.
Embodiment described above is only to be described preferred implementation of the present utility model, not to this practicality
Novel scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this
Various deformation that the technical scheme of utility model is made and improvement, all should fall into the protection that this utility model claims determine
In the range of.
