DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a refrigeration system, and more particularly to a refrigeration system without a compressor and without waste heat. [Prior Art] Fig. 1 shows a conventional air conditioner 1 which is suitable for cooling a foreign body with a refrigerant as a medium, and includes a compressor 11 for compressing a refrigerant into a high temperature and high pressure, and cooling a high pressure gaseous refrigerant into a liquid state. The condensing tube 12, a capillary tube 13 for reducing the pressure of the small liquid refrigerant and vaporizing the refrigerant, an evaporator 14 for replacing the refrigerant with the external heat master, and a connecting tube 15, which is connected to the compressor 11 and the condensing tube in sequence. 12. Capillary 13 and evaporator 14. Although the air conditioner 1 has the effect of cooling the outside world, it has the following disadvantages: 1. The compressor Π needs to compress the gaseous refrigerant to a high temperature state, which consumes a large amount of energy, resulting in a lack of energy consumption. Second, the compressor 11 is expensive, resulting in a lack of cost increase in the production of the air conditioner. 3. When the refrigerant is cooled in the condenser 12, a large amount of waste heat is generated to escape into the air. In addition to the waste heat energy, it also has an adverse effect on the environment. SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a non-compressor and waste heat-free refrigeration system that can save energy, save production costs, and is environmentally friendly. &> i invention of a compressor-free and waste heat-free system is suitable for 201005241 to use the refrigerant as a medium to cool the outside world, and includes a storage tank unit-conveying unit and a refrigeration unit. The cartridge unit includes a hollow cartridge having a liquid portion in which the liquid refrigerant is contained and a gaseous portion containing the gaseous refrigerant. The conveying unit includes a conveying pipe, and a driving pump disposed on the conveying pipe and accelerating the flow rate of the refrigerant in the conveying pipe. The delivery tube has a liquid section that communicates with the liquid portion, and a mixing section that communicates between the liquid section and the gaseous section. The refrigeration unit includes a pressurizing pump, an expansion element, an evaporator, and a refrigerant traveling pipe that sequentially communicates the liquid portion, the pressure pump, the expansion element, the evaporator, and the mixing section. The pressurized pump pushes the liquid refrigerant, which reduces the pressure of the refrigerant and vaporizes the refrigerant, and the refrigerant of the evaporator cools the outside temperature. The refrigeration system of the present invention having no compressor and no waste heat has the effect that the system returns the refrigerant to the liquid state by means of sprinkling and condensing, so that the compressor is not required, energy saving, production cost saving and environmental protection are saved. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 2, the first preferred embodiment of the refrigeration system without compressor and without waste heat of the present invention is suitable for cooling the outside world with a refrigerant as a medium, and comprises a storage tank unit 3, a conveying unit 4 and a refrigeration unit 5. . 201005241 The cartridge unit 3 includes a hollow cartridge 31 and a spray condenser 32 disposed within the cartridge 31. The cartridge 31 has a liquid portion 311 containing a liquid refrigerant, and a gas portion 312 which communicates with the liquid portion 311 and is located above the liquid portion 311 and accommodates a gaseous refrigerant. The conveying unit 4 includes a conveying pipe 41, and a driving pump 42 disposed on the wheel feeding pipe 41 and accelerating the flow rate of the refrigerant in the conveying pipe 41. The conveying pipe 41 has a connection with the liquid portion 311. A liquid section 411 for the drive pump 42 and a mixing section 412 that communicates with the liquid section 411 and the gaseous portion 312. The mixing section 412 is in communication with the spray condenser 32, and a portion of the gaseous refrigerant condenses into a liquid state within the spray condenser 32. The refrigeration unit 5 includes a pressurizing pump 51, an expansion element 52, an evaporator 53, and a serial communication between the liquid portion 311, the pressurizing pump 51, the expansion member 52, the evaporator 53, and the mixing section. The refrigerant traveling tube 54 of 412. The refrigerant traveling pipe 54 has a connecting section 541 which is sequentially connected to the liquid portion 311, the pressurizing pump 51, the expanding member 52 and the evaporator 53, and three branching sections 542 connecting the evaporator 53 and the mixing section 412. The pressurizing pump 51 pushes the liquid refrigerant, and the expanding member 52 is a capillary tube which reduces the waste force of the liquid refrigerant and vaporizes the refrigerant, and the refrigerant of the evaporator 53 cools the outside temperature. Referring to Fig. 3, the principle of the present invention utilizes a phenomenon of spray condensation in which the gaseous refrigerant is small particles 91, and the liquid refrigerant is a large particle 92' gas, a liquid refrigerant downward, and a small particle 91. A large particle 92' is attached to cause most of the gaseous refrigerant to condense into a liquid state. Referring to Fig. 2, the liquid and gaseous refrigerants coexist in the cylinder 31 at 201005241 170 psi (the values are only for reference, different refrigerants have different values), and the liquid refrigerant flows into the liquid section 411 from the liquid portion 311 simultaneously. And the refrigerant traveling pipe 54. The liquid refrigerant flowing into the refrigerant traveling pipe 54 is pressurized by the pressure pump 51 to about 220 psi, and then flows down into the expansion member 52 to be depressurized and vaporized, and flows to the evaporator 53 to lower the temperature of the outside. At this time, the refrigerant is in a gaseous state. The pressure is approximately 50 psi. The liquid refrigerant flowing into the liquid section 411 is accelerated by the driving pump 42, and the pressure is lowered due to the relationship of the law of Cannulli, so that when the mixing section 412 is introduced, the gaseous refrigerant in the refrigerant traveling pipe 54 will be Φ Inhalation. After the gaseous refrigerant in the mixing section 412 is mixed with the liquid refrigerant, a part of the gaseous refrigerant which gradually condenses into a liquefied refrigerant 'and has not yet condensed into a liquid state will condense into a liquid state after flowing into the spray condenser 32, and the self-spraying condenser Part of the gaseous refrigerant flowing out of 32 also causes spray condensation in the gaseous portion. After the compressor-free and waste heat-free refrigeration system is started, the gaseous and liquid mixed refrigerant is continuously sprinkled from the mixing section 412, and the condensed liquid refrigerant continuously flows out from the liquid section 411 and the refrigerant traveling pipe 54, and The above _ process continues to loop. In summary, the refrigeration system without compressor and waste heat of the present invention has the following effects: 1. The pressurized pump 51 only needs to pressurize the liquid refrigerant, and the driving pump 42 only needs to increase the flow speed of the liquid refrigerant. The energy required is less than the completion of the compressor and has the energy-saving effect. Second, no need for expensive compressor 11, you can achieve the cooling effect 'to achieve the effect of reducing production costs." 201005241 Second, no need for the condenser 12, a small amount of waste heat to the air can save energy, Also achieve a more environmentally friendly effect. Referring to Figure 4, a second preferred embodiment of the refrigeration system without compressor and without waste heat of the present invention is substantially identical to the first preferred embodiment, except that the spray cylinder unit 3 omits the spray condensation. The refrigerant 32 in the mixing section 412 directly flows into the cartridge 31, whereby the phenomenon of sprinkling and condensing can be generated in the same manner, and the above-mentioned effects are achieved, and the structure is also simple. It is worth mentioning that the expansion element 52 of the refrigeration unit 5 can be replaced by an expansion valve, which can also reduce the pressure of the refrigerant and vaporize the refrigerant. In addition, the branch section 542 can also be designed according to the flow rate. The divergence section 542, by which the same effect can be achieved. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
