Description
Technical Field
The utility model relates to a conversion of solar energy and utilization technical field especially relate to a refrigerating system of solar drive's electric heater defrosting.
Background
In the world today, most of the human resources available are non-renewable resources, and energy crisis is gradually growing to different extents around the world. The overuse of fossil energy has greatly destroyed the environment in which humans live and develop. Therefore, energy conservation and environmental protection become hot topics in the modern times. Because some electricity is generated by burning fossil energy (non-renewable energy such as coal and natural gas), electricity is very necessary to be saved, and the shortage of global resources is relieved. Solar energy is renewable energy and easy to obtain, and the method for obtaining electric energy by using solar energy is a very effective method.
When the evaporator is used for refrigerating, because the surface temperature of the evaporator is reduced, when water vapor in air is more, the water vapor can frost on the surface of the evaporator, the heat transfer resistance of the evaporator is increased, and the performance of the evaporator is deteriorated. Therefore, how to effectively defrost and reduce the energy consumption of defrosting are important problems to be solved urgently. The conventional single defrosting method does not solve the problem of frosting well, hot gas defrosting heats up uniformly and defrosts quickly, but the refrigerant must be stored in the liquid reservoir for a long time, the optimum utilization of the supercooling process is not achieved, and the compressor is easy to wet compress. However, the drainage of water does not increase the secondary frost rate in time. Electric heater defrost refers to the heating of the tubes by external tubes heated by external resistance wires. The method has the advantages of quick defrosting, simple pipeline design, easy realization of automatic control and the like, but has larger total power consumption.
SUMMERY OF THE UTILITY MODEL
For overcoming the deficiencies of the above system, the utility model provides a solar drive's refrigerating system that electric heater defrosts.
The utility model relates to a solar energy driven electric heater defrosting refrigeration system, which consists of a solar power generation system and a vapor compression refrigeration system, wherein the solar power generation system comprises a solar cell panel, a solar controller and a storage battery pack which are connected in sequence, and the storage battery pack is respectively connected with a storage battery management control system and an electric heater for defrosting; the vapor compression refrigeration system comprises a compressor, a condenser, a throttle valve and an evaporator which are connected in sequence, wherein the outlet of the evaporator is connected with the inlet end of the compressor.
The utility model has the advantages that:
1. the electric heater is driven by solar energy to replace a single electric heater for defrosting, so that the defect of electric energy consumption of the electric heater is overcome, and the solar defrosting device is energy-saving and environment-friendly.
2. The electric heater is adopted for defrosting, the defrosting speed is high, the pipeline design is simple, and the implementation is easy.
3. Thermoelectric modules used by the solar power generation system and the storage battery pack module have the advantages of light weight, small size, no moving parts, long service life, convenience in movement, high reliability, no pollution and the like. No matter what working condition the refrigerating system is under, the solar system can stably supply power to the storage battery pack. Refrigeration working media do not need to be filled, and the solar power generation utilization system is efficient and environment-friendly.
Drawings
FIG. 1 is a simplified flow diagram of a refrigeration system for defrosting a solar powered electric heater.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description.
Referring to fig. 1, it is composed of a solar power generation system and a vapor compression refrigeration system: the solar power generation system comprises a solar cell panel 6, a solar controller 7 and a storage battery pack 8 which are sequentially connected, wherein the storage battery pack 8 is respectively connected with a storage battery management control system 9 and an electric heater for defrosting 5; the vapor compression refrigeration system comprises a compressor 1, a condenser 2, a throttle valve 3 and an evaporator 4 which are connected in sequence, wherein the outlet of the evaporator 4 is connected with the inlet end of the compressor 1.
In the refrigeration cycle without defrosting, the storage battery pack does not work, low-temperature low-pressure refrigerant gas from the evaporator 4 enters the compressor 1, is compressed and then becomes high-temperature high-pressure refrigerant gas, enters the condenser 2, is cooled by coolant to become high-temperature high-pressure liquid, enters the throttle valve 3, is throttled and depressurized and then becomes two-phase fluid under the evaporation pressure, enters the evaporator 4 to absorb heat and then returns to the air suction port of the compressor 1.
The solar panel 6 absorbs radiant energy from the sun, and the solar energy is converted into electric energy through the solar controller 7 and stored in the storage battery module 8. When the evaporator 4 runs for a period of time, the surface of the evaporator 4 frosts, and when defrosting is performed, the storage battery pack 8 works through the storage battery management control system 9, discharging is performed on the electric heater 5, the electric heater 5 releases heat to the frost layer on the surface of the evaporator 4, and the frost layer absorbs the heat released by the electric heater 5 until the frost layer is melted completely.
While the present invention has been described above with reference to the accompanying drawings, it is not limited to the above specific embodiments, which are illustrative only and not restrictive. The change under the flow of the utility model is within the protection of the utility model.
