Embodiment 1
[0020] Embodiment 1, figure 1 A refrigeration device and method for self-recovery of expansion work is given, which is mainly realized by setting up a related centrifugal device, and a potential field is provided by the centrifugal device.
[0021] The expansion work self-recovery refrigerating device includes a supergravity generating device and a refrigerating device with a built-in working medium; the supergravity generating device is a base 1 arranged on a rotating shaft 2; the refrigerating device is an evaporator 3, a condenser 5, and Compressor 4; specifically, the evaporation pipeline of evaporator 3 is connected to compressor 4 (or connected to each other through other pipelines I, since no additional Centrifugal force is generated, so it can be directly connected or connected through a short pipeline I); the condensation pipeline of compressor 4 and condenser 5 is connected through pipeline II (according to the actual use process, due to the condensation of compresso...
Embodiment approach
[0023] Its specific implementation method is as follows:
[0024] 1. The rotating shaft 2 drives the base 1 to rotate at a certain angular velocity (the angular velocity is set according to the site conditions);
[0025] 2. The base 1 drives the evaporator 3, the condenser 5, and the compressor 4 to rotate at a certain angular speed;
[0026] 3. The low-pressure gas flowing out of the evaporator 3 enters the compressor 4, is pressurized by the compressor 4 to medium pressure, and the temperature rises, and then flows adiabatically in the pipeline II to the condensation pipeline of the condenser 5 under the joint action of centrifugal force and pressure difference When it is further pressurized to high pressure, the inertial potential energy decreases, and the temperature rises further. After the high-pressure gas releases heat to the external high-temperature cold source in the condenser 5, it becomes a high-temperature and high-pressure liquid;
[0027] 4. When the high-temp...
Embodiment 1
[0032] The calculation parameters for implementing Example 1 are shown in Table 1 (for 1kg of working fluid R134a). The design conditions are: the working fluid is R134a, the condensation temperature is 40°C, the evaporation temperature is 0°C, and the turning diameter is 1m. The system COP (defined as the ratio of the heat absorption of the evaporator to the theoretical power consumption of the compressor) calculated by the implementation example 1 is 6.81. The exhaust heat of the evaporator is 168.2kJ / kg, the dryness of the refrigerant at the inlet of the evaporator is 0.262, and the transmitted inertial potential energy is 4.38kJ / kg. Compared with the existing refrigerating system using expansion valve (see Table 1, its COP is 5.49), the COP of implementation example 1 has been promoted by 24%, thus it can be seen that the present invention recycles the expansion work by virtue of the participation of inertial potential energy , the adiabatic depressurization loss of the e...
