Abstract
The utility model relates to a refrigeration system, in particular to a refrigeration system used for a refrigerator and more particularly to a refrigerator refrigeration system with a controller. The refrigeration system comprises a compressor body, an evaporator communicated with one end of the compressor body and a condenser communicated with the other end of the compressor body. The circuit input end of the compressor body is provided with a circuit controller. The utility model has simple structure and reasonable design and can be made based on the alteration of the existing refrigerator. The refrigeration system achieves high power in the startup of the refrigerator and after reaching required temperature, the compressor switches to lower power to keep on operating without stopping. The lower power is equal to the whole day power consumption of the refrigerator divided by time, thus maintaining more stable temperature and having the energy saving effect.
Description
Technical field
The utility model relates to a kind of refrigeration system, refers in particular to the employed refrigeration system of refrigerator, is specially a kind of refrigerator refrigeration system that has controller.
Background technology
Compressor is the heart of refrigerator refrigeration system, it sucks the refrigerant gas of low-temp low-pressure from air intake duct, after driving piston (or impeller) it is compressed by motor rotation, discharge the refrigerant liquid of HTHP to blast pipe, for kind of refrigeration cycle provides power, thus the kind of refrigeration cycle of realization compression → condensation → expansion → evaporation (heat absorption).Compressor generally is made up of housing, motor, cylinder body, piston, control appliance (starter and thermal protector) and cooling system.The compressor of general domestic refrigerator and air-conditioner be with single-phase alternating current as power supply, their structural principle is basic identical.Freezer compressor power is less, usually below 250W.
The refrigeration system of refrigerator comprises compressor body, the evaporimeter that is connected with an end of compressor body, the condenser that is connected with the other end of compressor body.The refrigeration of refrigerator is the heat absorption phenomenon of utilizing in the states of matter change procedure, makes it the gas-liquid circulation, and heat absorption and heat release constantly is to reach the purpose of refrigeration.Its detailed process is: energising back compressor operating, low pressure, the cryogenic gaseous cold-producing medium that has absorbed heat in the evaporimeter sucked, and after compression, formation temperature is 55 ℃～58 ℃, pressure is high pressure, the high-temp liquid of 112008 handkerchiefs, enters condenser.Because throttling capillaceous sharply reduces pressure.Because of the evaporimeter internal pressure is lower than condenser pressure, just explosive evaporation immediately of liquid refrigerant, the heat in the respiratory box becomes the steam of low pressure, low temperature, is sucked by compressor once more.So constantly circulation is constantly transferred to the refrigerator inside heat outside the case.By above analysis, as long as we know compressor one work just have high pressure to exist in its body, and after outage, could disappear the section of the having time, Here it is reason place that why refrigerator can not start shooting after shutdown immediately.Its inherent mechanism is: refrigerator is in running, and the suction side of its refrigeration system compressor is a low-pressure side, and its pressure is a little more than atmospheric pressure.The row pressure side of compressor is the high-pressure side; pressure up to 117007 handkerchiefs about; the pressure difference of both sides very big (pressure differential also is very big); shut down back two side systems and still keep this pressure differential; if start immediately; compressor piston pressure strengthens; pressing moment and can not overcoming such pressure differential of motor makes the motor fail to start, is in the stall state; this just makes the faster rotational speed of rotating excitation field with respect to rotor; the rate of change of magnetic flux has strengthened, thereby causes the current surge of motor winding, and temperature raises; if the time is long, probably burn motor.Therefore spending 4～5 minutes after all refrigerators all require to shut down just can restart.
Yet, the compressor of current refrigerator will start tens times in one day, and when temperature reached requirement, compressor just quit work, when temperature departure requires temperature, compressor just starts again starts working, and until reaching the requirement temperature once more, and only opens refrigerator easily one time, the cold air loss, compressor must turn round tens of minutes more, could recover required refrigerated storage temperature, and this also consumed one of reason of about 5-kilowatt hour electric power just in every month.When the starting current of compressor is work tens times more can expend a large amount of electric energy during startup.If the power in the time of can allowing refrigerator start is big, remain in operation for less power compressor converted again when meeting the requirements of temperature by the time.Less power approximates refrigerator whole day power consumption/time.Refrigerator just need not have been shut down like this, and stablizing of also can keeping of temperature, can play energy-conservation effect.
Summary of the invention
The utility model provides a kind of freezer compressor that has controller to achieve these goals.
The utility model is to adopt following structure to realize above-mentioned purpose: a kind of refrigerator refrigeration system that has controller comprises compressor body, the evaporimeter that is connected with an end of compressor body, the condenser that is connected with the other end of compressor body; The circuit input end of compressor body is provided with circuit controller.So-called circuit controller refers to the device that can control curtage, as rectifier.
The utility model is simple in structure, and is reasonable in design, and can be transformed to make on the basis of current refrigerator becomes the utility model.Power when the utility model has realized that refrigerator starts is big, when meeting the requirements of temperature by the time, compressor convertedly remains in operation for less power, and does not stop.Less power equals refrigerator whole day power consumption/time.Keep more stable temperature, played energy-conservation effect.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
A kind of refrigerator refrigeration system that has controller comprises compressor body 1, the evaporimeter 2 that is connected with an end of compressor body 1, the condenser 3 that is connected with the other end of compressor body 1; The circuit input end of compressor body 1 is provided with circuit controller 4.
The foregoing circuit controller can be rectifier.The circuit of rectifier is set to prior art.
For further energy-conservation, the interior pressure reduction in the time of can allowing the compressor operating of refrigerator (pressure of condenser compressed side and evaporator evaporation side poor) is smaller as far as possible, with liquefaction just with just be evaporated to.The evaporation pressure of general daily refrigerator is that this pressure is too little about 1 atmospheric pressure, should be higher again, and just passable with the pressure that liquid can evaporate.Can dwindle interior pressure reduction like this, improve the efficient of compressor, improve heat and imitate ratio.Can be energy-conservation.
The method of pressure reduction is in reducing: suppose that a kind of cold-producing medium just can liquefy under 20 atmospheric pressure, just can evaporate under 10 atmospheric pressure that we can be added to 15 atmospheric pressure to his interior pressure when shutting down so.When work just can allow the high-pressure side be 20 atmospheric pressure by running like this, and the evaporator evaporation side is 10 atmospheric pressure.And general refrigerator is that condenser liquefaction side is 20 atmospheric pressure, and the evaporator evaporation side is 1 atmospheric pressure.Clearly, the former is 10 interior pressure reduction, and the latter is 19 interior pressure reduction, and the former is more energy-conservation.
