In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the air conditioning device capable of generating power and outputting power all weather comprises a turbine power generation device 1, a pressure conversion device 2 and a heat absorption heat exchanger 3, wherein the turbine power generation device 1, the pressure conversion device 2 and the heat absorption heat exchanger 3 are communicated in a sealed mode through pipelines, and the heat absorption heat exchanger 3 is arranged in a using space 4 and can exchange heat with air 42 in the using space 4.
After the carbon dioxide 36 pushing the turbine power generation device 1 to generate power flows out of the turbine power generation device 1, the carbon dioxide is converted by the pressure conversion device 2 and finally enters the heat absorption heat exchanger 3, the carbon dioxide 36 entering the heat absorption heat exchanger 3 is in a low-temperature and low-pressure state, and in the throttling flowing process of the heat exchange tube 37, the carbon dioxide absorbs the heat of the air 42 flowing through the outer surface of the heat exchange tube 37 and in the use space 4, so that the temperature of the air 42 is reduced, and the temperature of the use space 4 is adjusted; meanwhile, after absorbing the heat of the air in the use space 4 in the heat exchange tube 37, the carbon dioxide 36 expands in volume and increases in pressure, enters the closed space of the pressure conversion device 2, is subjected to cyclic compression and reversing of the pressure conversion device 2, and further increases in pressure, and finally continuously flows to the turbine power generation device 1, so that all-weather power generation for 7 × 24 hours is realized.
At least one pair of the closed spaces of the pressure conversion devices 2 are independent from each other and are symmetrically arranged; the working principle of the pressure conversion device 2 can be referred to fig. 1 and 5.
In order to effectively utilize the pressure value change of the carbon dioxide 36, convert the pressure energy into mechanical energy through conversion, and continue to compress the carbon dioxide 36, thereby achieving the purpose of saving energy, preferably, the pressure conversion device 2 comprises a four-way reversing valve 21, a 1 st piston cylinder 23 and a 2 nd piston cylinder 24; the 1 st and 2 nd piston cylinders 23 and 24 are provided in a pair and are arranged symmetrically with respect to each other.

The process of compressing carbon dioxide 36 is as follows:
after the 1 st piston 231 and the 2 nd piston 241 move to the upper limit positions, the heat absorption heat exchanger 3 exchanges heat, the expanded carbon dioxide 36 absorbs heat flows out of the 1 st storage tank 35, and then the expanded carbon dioxide enters the upper cavity of the 1 st piston cylinder 23 through the 2 nd outflow pipe 34 and the 7 th electromagnetic valve 33 of the heat exchanger to push the 1 st piston 231 to move downwards, and the 2 nd piston 241 is driven to move downwards through the piston rod 232 to compress the carbon dioxide 36 entering the lower cavity of the 2 nd piston cylinder 24.
The carbon dioxide 36 entering the cavity under the 2 nd piston cylinder 24 is the carbon dioxide 36 stored in the 2 nd storage tank 38, and flows into the cavity under the 2 nd piston cylinder 24 through the 1 st outflow pipe 31 of the heat exchanger, the check valve 26.
When the 2 nd piston 241 is driven to move downwards, carbon dioxide entering the cavity below the 2 nd piston cylinder 24 is compressed, the pressure of the compressed carbon dioxide 36 is further increased, the compressed carbon dioxide passes through the opened 2 nd electromagnetic valve 25, enters the 1 st air pipe 211 of the four-way reversing valve, passes through the 3 rd air pipe 213 of the four-way reversing valve 21, flows out of the four-way reversing valve 21, flows into the inlet 12 of the turbine power generation device, pushes the turbine blades 11 to rotate, drives the turbine shaft 13 which is fixedly arranged concentrically with the turbine blades 11 to rotate, drives the generator 14 which is coaxially arranged with the turbine shaft 13 to generate electricity, and the generated electricity is output through the generator power output end 141, flows into the energy storage device power input end 61 and is stored in the energy storage device 6.

The pressurizing device 5 is preferably a pressurizing pump, but other pressurizing equipment with a suitable structure can be selected.
When the carbon dioxide 36 can enter the 2 nd storage tank 38 by utilizing the pressure of the carbon dioxide 36 itself, the 8 th electromagnetic valve 52 can be opened, the carbon dioxide bypasses the pressurizing device 5 and directly flows into the 2 nd storage tank 38, in the actual use, the pressure in the carbon dioxide 36 in the 2 nd storage tank 38 is lower than the pressure of the carbon dioxide 36 flowing out of the 2 nd air pipe 212 of the four-way reversing valve in consideration of the circulating flow of the carbon dioxide 36 in the heat absorption heat exchanger 3, in general, the carbon dioxide can be pressed into the 2 nd storage tank 38 only by the pressure of the carbon dioxide 36 itself, and the pressurizing device 5 is added to assist in ensuring that the carbon dioxide 36 stably flows into the 2 nd storage tank 38.
In practical use, it is also considered that the turbine power generation device 1 and the pressure conversion device 2 are arranged higher than the 2 nd storage tank 38, and the carbon dioxide 36 flows into the 2 nd storage tank 38 more smoothly by the action of gravity.
In the above operation, the four-way reversing valve 21 is de-energized, the 1 st solenoid valve 22, the 4 th solenoid valve 28, and the 6 th solenoid valve 32 are in the closed state, the power required by the pressure device 5 and the solenoid valves can be output through the energy storage device power output end 62 of the energy storage device 6 and supplied through the pressure device power input end 51, if the pressure device 5 is used, the 8 th solenoid valve 52 is closed, and if the pressure device 5 is not used, the 8 th solenoid valve 52 is opened.
When the 1 st piston 231 and the 2 nd piston 241 move to the lower limit positions, at the same time, the four-way reversing valve 21 is electrified, the 7 th electromagnetic valve 33 is closed, the 4 th electromagnetic valve 28 and the 6 th electromagnetic valve 32 are opened, heat is exchanged through the heat absorption heat exchanger 3, the heat-absorbed and expanded carbon dioxide flows out of the 1 st storage tank 35, enters the lower cavity of the 2 nd piston cylinder 24 through the 2 nd outflow pipe 34 and the 6 th electromagnetic valve 32 of the heat exchanger, the 2 nd piston 241 is pushed to move upwards, the carbon dioxide 36 stored in the 2 nd storage tank 38 flows into the upper cavity of the 1 st piston cylinder 23 through the 1 st outflow pipe 31, the 4 th electromagnetic valve 28 and the 1 st piston cylinder air pipe 233 of the heat exchanger, the 1 st piston 141 is driven to move upwards through the piston rod 232 when the 2 nd piston 241 moves upwards, the carbon dioxide 36 entering the upper cavity of the 1 st piston cylinder 23 is compressed, and the compressed carbon dioxide 36 is passed through, the pressure is further increased, then the pressure enters a 5 th air pipe 215 of the four-way reversing valve through the opened 1 st electromagnetic valve 22, then flows out of the four-way reversing valve 21 through a 3 rd air pipe 213 of the four-way reversing valve 21, flows into an inlet 12 of the turbine power generation device, pushes the turbine blades 11 to rotate, drives a turbine shaft 13 which is concentrically and fixedly arranged with the turbine blades 11 to rotate, thereby driving a generator 14 which is coaxially arranged with the turbine shaft 13 to operate and generate power, and the generated power is output through a power output end 141 of the generator, flows into a power input end 61 of the energy storage device and is stored in the energy storage device 6.
The pressure and temperature of the carbon dioxide 36 which finishes pushing the turbine power generation device 1 to generate electricity become low, and after the carbon dioxide 36 flows out of the outlet 15 of the turbine power generation device, the carbon dioxide 36 with low temperature and low pressure enters the 4 th air pipe 214 of the four-way reversing valve, flows out through the 1 st air pipe 211 of the four-way reversing valve 21, flows through the 5 th electromagnetic valve 29, and finally flows into the 2 nd storage tank 38, and the inflow means and method are the same as the compression when the 1 st piston 231 and the 2 nd piston 241 move downwards, and the description is not repeated.
By the above-mentioned cyclic reciprocating compression between the 1 st piston 231 and the 2 nd piston 241, the carbon dioxide 36 can be continuously compressed to drive the turbine power generation device 1 to generate power.
In order to further control the pressure values of the carbon dioxide 36 compressed by the 1 st piston 231 and the 2 nd piston 241 to achieve the purpose of increasing the power generation amount of the turbine power generation device 1 under the condition of needing less energy consumption, preferably, the absolute value of the pressure of the carbon dioxide 36 compressed by the 1 st piston 231 and the 2 nd piston 241 is 0.5-9 Mpa, and the controlled pressure value can be selected according to factors such as the required power generation amount, for example, when 0.5Mpa is selected, the power generation amount of the turbine power generation device is small, when 5Mpa is selected, the power generation amount is large, when 9Mpa is selected, the power generation amount is more, and the pressure value can be selected according to the actual situation to meet the use requirement.
In addition to the above-mentioned 1 st piston cylinder 23 and 2 nd piston cylinder 24 which form a pair and are symmetrically arranged with each other, in order to increase the carbon dioxide compression amount and thus achieve the purpose of increasing the power generation amount, the piston cylinders can be arranged in more pairs, and in order to increase the operation reliability, 1 to 6 pairs are preferred, and according to the use requirement, 1 pair, 4 pairs and 6 pairs can be selected, wherein the more the pairs are, the larger the compression amount is, the more the power generation amount is, but the operation reliability is relatively low.
