Description
Technical field
The utility model relates to a kind of refrigerating system, specifically a kind of refrigerating system be used on boats and ships.
Background technology
Domestic do not have special to be equipped with Variable Cooling Water Flow amount device for refrigerating system peculiar to vessel, and what have is also only equipped with the flow that condensation pressure regulation valve does not have controlled cooling model water.
At least there is following shortcoming in prior art:
1. existing messes cold storage plant peculiar to vessel can not change the flow of cooling water when cooling water temperature changes (fluctuation), cooling water flow velocity may be caused too high, especially cooling medium is the cold storage plant of seawater, and cooling water flow cannot regulate and cause that flow velocity is too high can accelerate the corrosion of seawater to condenser;
2. in the winter time, cause the high pressure of compressor to reduce causing low pressure also can reduce and pressure oscillation is comparatively large when cooler-water temperature reduces, system is run under being in extremely low evaporating temperature for a long time, can make compressor motor overheating, also can cause high frequent start and stop, thus reduce the service life of compressor;
3. the setting of condensation pressure regulation valve is cumbersome, and pressure is difficult to calibration;
4. refrigeration system energy conditioner (low voltage control compressor capacity controlling gear) is difficult to maintain nominal situation, even running.
Utility model content
The utility model is intended to solve messes cold storage plant peculiar to vessel when fluctuation occurs coolant water temperature, and the flow of cooling water can not carry out the problem regulated according to the change of condenser pressure; Solving that the refrigeration system low pressure fluctuation caused due to cooling water causes more greatly can the problem of regulating mechanism frequent movement.
For solving the problem, the utility model provides a kind of seawater variable-flow refrigerating system, comprise compressor 2, condenser 4, expansion valve 8, evaporimeter 10, described compressor 2 one end is connected with condenser 4, the other end of described condenser 4 is connected with expansion valve 8, the other end of described expansion valve 8 is also connected with the evaporimeter 10 be communicated with described compressor 2, it is characterized in that: the pipeline that described condenser 4 is connected with cooling water is also provided with pressure regulation pipeline, described pressure regulation pipeline is provided with a cooling water inflow control valve 6 and cooling-water temperature sensor 7, described cooling water inflow control valve 6 can regulate the flow of cooling water automatically according to the pressure change of condenser, when the pressure at expulsion of described compressor 2 raises, tune up amount of cooling water control valve, more cooling water enters in condenser 4, when the pressure at expulsion of described compressor 2 reduces, turn amount of cooling water control valve 6 down, less cooling water enters in condenser 4, when cooling water temperature raises, tune up amount of cooling water control valve 6, more cooling water enters in condenser 4, when cooling water temperature reduces, turn amount of cooling water control valve 6 down, less cooling water enters in condenser 4, and described cooling water is seawater.
As further improvement of the utility model, one end of described condenser is connected with at least two expansion valves, and each described expansion valve is also all connected with evaporimeter.
The beneficial effects of the utility model are, solve messes cold storage plant peculiar to vessel when fluctuation occurs coolant water temperature, the flow of cooling water can not carry out the problem regulated according to the change of pressure; Solving that the refrigeration system low pressure fluctuation caused due to cooling water causes more greatly can the problem of regulating mechanism frequent movement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 2-compressor; 4-condenser; 6-cooling water inflow control valve; 7-cooling-water temperature sensor; 8-expansion valve; 10-evaporimeter.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, the utility model provides a kind of seawater variable-flow refrigerating system, comprise compressor 2, and be connected to the condenser 4 on described compressor 2 with one end, the other end of described condenser 4 is connected with expansion valve 8, the other end stating expansion valve 8 is also connected with the evaporimeter 10 be communicated with described compressor 2, described condenser 4 is also provided with pressure regulation pipeline, described pressure regulation pipeline is provided with a cooling water inflow control valve 6 and cooling-water temperature sensor 7, described cooling water inflow control valve 6 can regulate the flow of cooling water automatically according to condensing pressure change, when the pressure at expulsion of described compressor 2 raises, tune up cooling water inflow control valve, more cooling water enters in condenser 4, when the pressure at expulsion of described compressor 2 reduces, turn amount of cooling water control valve 6 down, less cooling water enters in condenser 4, when cooling water temperature raises, tune up amount of cooling water control valve 6, more cooling water enters in condenser 4, when cooling water temperature reduces, turn amount of cooling water control valve 6 down, less cooling water enters in condenser 4, and described cooling water is seawater.
As further improvement of the utility model, one end of described condenser 4 is connected with at least two expansion valves 8, and each described expansion valve 8 is also all connected with evaporimeter 10.
The overheated high steam that the compressor 2 freezed when using messes refrigerating system function peculiar to vessel is discharged is cooled by the heat exchanger tube of the inside of marine condenser 4, overheated steam is made to become subcooled liquid, cross cold liquid and cause some refrigerant gasification through the effect of expansion valve 8 reducing pressure by regulating flow, make the also corresponding reduction of cold-producing medium self-temperature, become low-temp low-pressure two-phase fluid, enter air cooler evaporator 10 evaporation endothermic, overheated gas enters compressor 2 and enters next circulation subsequently.
Cooling water inflow control valve 6 on the drain pipe of condenser 4 and the outlet pipe of condenser 4, regulates the flow of cooling water according to condensing pressure change.When the pressure at expulsion of compressor 2 raises, valve leaves greatly automatically, makes more cooling water enter condenser 4, accelerates the speed of condensation of refrigerant; Otherwise when discharge pressure declines, valve turns down automatically, the cooling water inflow of infeed is reduced.Thus system pressure (high pressure, low pressure) is remained in certain scope.
Adopt in this way, solve messes cold storage plant peculiar to vessel when fluctuation occurs coolant water temperature, the flow of cooling water can not carry out the problem regulated according to the change of pressure; Solving that the refrigeration system low pressure fluctuation caused due to cooling water causes more greatly can the problem of regulating mechanism frequent movement.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
