Description of the Invention: [Technical Field] The present invention relates to a device and method for generating electric power and cold using low-order thermal energy, and more particularly to a user who can use two according to the demand of electric power or freezing. The control valve member (such as three-way valve) can change the working fluid flow direction, and switch between operation modes such as cold electricity, freezing, power generation or idling, so that the system heat energy can be optimally and diversified, so as to fully exert energy-saving effects. And reduce greenhouse gas emissions. Participation [Prior Art] With the advancement of technology and the increase in population, energy consumption is much higher than in the past. Excessive use of fossil energy, causing a large amount of carbon dioxide emissions, causing the greenhouse effect 'to make global climate change abnormal. Therefore, solving energy shortages and reducing greenhouse gas emissions has gradually become a major challenge for the international community, and it is the bottleneck for human beings to pursue sustainable survival. In addition to the development of renewable energy, the use of old energy is also a major focus. In the past, for the old energy festival, the emphasis was placed on reducing energy waste and improving energy conversion efficiency. Until the energy conversion technology has been improved in recent years, the related technologies of waste heat recovery and reuse have gradually emerged, which has also caused energy shortage. A new dawn appeared. For high-grade waste heat with a temperature exceeding 500 °C, it is generally used as a waste heat reuse device by Combined Cycle Power Generation or Combined Heat and Power (CHP). However, for low grade waste heat of less than 300 ° C, such as melting, drying, heat treatment, steam and combustion in general industrial processes, it is rare to have a cost-effective heat recovery method. In general, low-level waste heat 201217728 cannot be directly converted to the factory process or power generation cycle, so that most of the workers will directly discharge them to the atmosphere. Only a few X plants use them to introduce heat exchangers (Exchanger) or complex A heat recovery device such as a heat exchanger (Recuperat〇r) is reused. Such heat and receiver devices need to be specially designed to be compatible with the process and can only be used as thermal energy. S This U thermal energy device, with a fine tilting cycle (ORC) system, has gradually gained attention, which can convert low-order thermal energy into high-order energy-electricity. This organic Rankine cycle is developed by the thermodynamically traditional Rankine steam power cycle, which has been used in steam power plants or steam engines for many years to solve the problem that the Carnot Cycle cannot work. The problem of complete phase change of the fluid; since the thermal energy level of general waste heat cannot be applied to the steam Rankine cycle to generate electricity at the output power, the water is replaced by other working fluids such as organic solvents to form an organic Rankine cycle, which can be The low-temperature waste heat is converted into electric power output, and can be developed into electric steam for industrial waste heat power generation, geothermal power generation, and even solar thermal power generation. According to Taipower's data, the electricity consumption of the residential/commercial sector has reached 31% of the country's total electricity consumption by 2005, of which 20% is residential and ιι〇/0 is used for commercial use. Lighting electricity accounts for a very high proportion. Therefore, effectively converting low-order thermal energy into electricity and refrigeration will help solve energy shortages and reduce greenhouse gas emissions. Traditionally, in order to recover low-order heat energy, such as industrial waste heat or waste heat, solar heat or geothermal heat, organic Rankine cycle is often used as a device for thermal power conversion. Please refer to Figure 3 for the organic Rankine cycle device. The basic component includes a heating module 20, a power generation module 2 1, a condensation module 22, and a pressurized pump 23. The heating module 20 is composed of a boiler 201 and a heat source 220 which heats the liquid working fluid flowing through the boiler 210 into a high-pressure working fluid of 201217728. The power generating module 2 1 is composed of the expansion turbine 2 1 1 and the generator 2 1 2 , and the high-pressure gaseous working fluid generated by the heating module 20 can push the expansion turbine 2 1 1 to work, and simultaneously drive The generator 2 1 2 generates electricity. The condensing module 2 2 is composed of a condenser 2 2 1 and a cooling water tower 22 2, after which the medium-pressure gaseous working fluid enters the condenser 2 2 1 'cycled by the cooling water tower 2 2 2 The ice water is condensed into a liquid working fluid, and finally pressurized by the pressurized pump 23 and sent to the heating module 20. When used, the heat source 2 0 2 may be industrial waste heat, solar heat or geothermal, etc., and use organic hydrocarbons, inorganic small molecule compounds (such as C02 and nh3, etc.) or fluorine-containing carbon compounds as working fluids. The thermal energy of low-order thermal energy is converted into useful mechanical energy or electrical energy; however, due to the low temperature of the low-order thermal energy, the thermal efficiency of the overall device is not high and can only be provided as a power generation. In order to improve the overall system performance, an energy generation method proposed by the Republic of China Patent Certificate No. 209954, as shown in Fig. 4, is a circulation device that can improve the efficiency of thermal power. The evaporator module 30 of the exchanger 3 〇1, the turbine generator set 31 of the two turbines 311, the condensation module 3 2, and the booster pump set 3 3 of the two pressurized pumps 3 31 form a single loop multiple The system of stress. Then, using the multiple pressure cycles of the working fluid and the arrangement of the heat exchanger, although the irreversibility of the heat source and the system can be reduced, and the multiple pressure cycles are used by the mixer 34, the superheated steam can be effectively utilized, and the energy utilization rate and thermal efficiency can be improved. However, its thermal energy conversion is limited to generating electricity. In view of this, the general practitioners cannot meet the needs of the user in actual use, and it is necessary to design a thermal energy utilization device of an improved organic Rankine cycle system to achieve optimal utilization and energy saving. It can simultaneously generate electricity and cool, not only saving energy consumption but also reducing greenhouse gas emissions. This is undoubtedly a problem that needs to be faced in this related research and development field in 201217728.
