The working principle and the using flow of the invention are as follows: when the special constant temperature and humidity ground source heat pump for the greenhouse is actually used, firstly, the ground source heat pump is fixedly arranged at a position to be operated through a base 1, then a guide pipe 321 on a guide head 315 is connected with an inlet of an external heating pipeline, a guide pipe 321 on the other guide head 315 is connected with an outlet of the external trifluoromethane conveying pipeline and the external heating pipeline through an external three-way valve, an eduction pipe connected with the inlet of the external heating pipeline is an eduction pipe in the guide pipe 321, an eduction pipe connected with the external trifluoromethane conveying pipeline is an inducted pipe in the guide pipe 321, the eduction pipe and the eduction pipe are in an unconnected state before, and then two ground connection pipes 217 are respectively connected with the inlet and the outlet of the external buried pipeline;
After the connection work is completed, the inertia wheel 205 can be rotated, an initial driving force is given to the ground source heat pump, the special constant temperature and constant humidity ground source heat pump for the greenhouse and the external trifluoromethane conveying device are started to perform heating work, after the external heating pipeline and the external buried pipeline are filled with the trifluoromethane, the external trifluoromethane conveying device can be closed, the circulating conveying of the trifluoromethane is performed through the special constant temperature and constant humidity ground source heat pump for the greenhouse, and the spontaneous heating work is performed by utilizing the temperature difference energy;
In the heating work, the special constant temperature and humidity ground source heat pump for the greenhouse firstly extracts the trifluoromethane in the external buried pipeline through the pumping pipe in the ground connection pipe 217, presses the trifluoromethane into the corresponding heat exchange cavity 219 through the conveying pipe in the guide pipe 216 under the flow-limiting guiding effect of the guide cylinder 215 and the check valve 218, and gasifies and absorbs heat in the external buried pipeline under the geothermal temperature effect, so that a large amount of heat is obtained, and after the trifluoromethane is pressed into the corresponding heat exchange cavity 219 according to energy conservation, the temperature of the trifluoromethane is further increased under the external pressure effect, so that the inside of the corresponding heat exchange cavity 219 presents a high-temperature environment;
Then, the pressurized and warmed up trifluoromethane enters the corresponding guide head 315 through the pressurizing pipe in the external pipe 220, and under the conduction of the flow channel 317, the gas-liquid balance state of the trifluoromethane in the pressure control box 316 gives a squeezing force to the sliding block 319 in real time, only the gas pressure of the pressurized and warmed up trifluoromethane is enough to overcome the squeezing force, the pressurized and warmed up trifluoromethane can enter the through groove 320 through the slideway 318 and enter the external heating pipeline through the guiding pipe in the corresponding guide pipe 321, at the moment, when the pressurized and warmed up trifluoromethane enters the external heating pipeline under the pressure regulation of the guide head 315, the gas pressure is larger than the critical pressure, and the external heating pipeline is a non-heat insulation material, so that the gas pressure can liquefy and release heat in the external heating pipeline to heat the greenhouse;
The liquefied trifluoromethane then enters the second guide head 315 through the ingress pipe in the corresponding conduit 321, and under the extrusion force of the trifluoromethane in the gas-liquid balance state in the pressure control box 316, the liquefied trifluoromethane can enter the through groove 320 through the slideway 318 only when the pressure is enough to overcome the extrusion force, and enter the second heat exchange cavity 219 through the corresponding egress pipe 220 through the corresponding egress pipe in the corresponding conduit 321, and enter the corresponding guide cylinder 215 through the return pipe in the guide pipe 216 under the drive of the ground source heat pump, and finally enter the external buried pipeline through the pressure pipe in the ground connection pipe 217 to form a complete circulation loop;
Under the flow-limiting guiding action of the two guide heads 315, the pressure of the trifluoromethane in the external heating pipeline is larger than the critical pressure, the pressure of the trifluoromethane in the external buried pipeline is smaller than the critical pressure, when the trifluoromethane enters the second heat exchange cavity 219, the special constant temperature and constant humidity ground source heat pump for the greenhouse extracts the air flow in the second heat exchange cavity 219 through the return pipe in the guide pipe 216, so that the pressure in the heat exchange cavity 219 is reduced, the liquid trifluoromethane entering the second heat exchange cavity 219 is subjected to primary gasification heat absorption due to the reduction of the external pressure, and the internal part of the external buried pipeline is further subjected to gasification heat absorption, so that the interior of the second heat exchange cavity 219 presents a low-temperature environment;
Meanwhile, in the circulating flow process of the trifluoromethane, the two heat exchange cavities 219 respectively show a high temperature state and a low temperature state, the local source heat pump takes the temperature difference energy as a driving force to drive the trifluoromethane to circulate, the temperature sensing barrel 201 embedded in the heat exchange cavity 219 in the high temperature state is a hot barrel, the other temperature sensing barrel 201 is a cold barrel, in the initial state, the piston block 202 in the cold barrel is at the bottommost position, and at the moment, the trifluoromethane at the bottom of the piston block 202 is pressed into the hot barrel through the communicating pipe 221;
At this time, the trifluoromethane in the heat cylinder is heated and expanded under the action of external high temperature, so that the pressure rises, and then under the action of the pressure, the two piston blocks 202 are simultaneously pressed up, and then drag the two push rods 203 to rise synchronously, and then under the action of the linkage of the steering head 204 and the guide rod 207, the deflection plate 206 drives the inertia wheel 205 to rotate;
When the piston block 202 in the hot cylinder rises to the highest point, the flywheel 205 continues to rotate due to inertia, and then drives the two push rods 203 in a reverse direction through the steering head 204, the deflection plate 206 and the guide rods 207, so that the piston block 202 in the hot cylinder sinks, and the piston block 202 in the cold cylinder continues to rise, and at the moment, the trifluoromethane at the bottom of the piston block 202 in the hot cylinder is gradually pressed into the cold cylinder through the communicating pipe 221;
When the piston blocks 202 in the cold cylinder rise to the highest point, under the action of external low temperature, the trifluoromethane in the cold cylinder contracts when encountering cold, so that the pressure at the bottoms of the two piston blocks 202 is reduced, and the two piston blocks 202 sink under the action of inertia, so that the two piston blocks 202 drive the two push rods 203 to sink synchronously, and under the action of the linkage of the steering head 204 and the guide rod 207, the inertia wheel 205 is driven to rotate continuously through the deflection plate 206;

While the piston plate 209 moves reciprocally synchronously, it drives the pressure raising plate 309 to move reciprocally synchronously in the conducting cavity 308 through the connecting rod 310, and then during the reciprocal displacement of the pressure raising plate 309, the hydraulic fluid in the conducting cavity 308 is pressed into the flow cavities in the two heat exchange cavities 219 from the two material guiding support cylinders 311 in turn, and is pressed into the circulation cavity 301 from the two flow ports 313 in turn, and the hydraulic fluid in the circulation cavity 301 is pressed into the conducting cavity 308 from the corresponding flow ports 313, flow cavities and material guiding support cylinders 311 in turn, so that the hydraulic fluid flows reciprocally in the conducting cavity 308 and the circulation cavity 301, and during the flow of the hydraulic fluid, the rotating wheel 302 continuously rotates under the action of the storing force groove 314, and then under the transmission action of the rotating shaft 303, the driving wheel 304, the shaft rod 305, the stacking wheel 306 and the driving belt 307, the inertia wheel 205 is driven to rotate by an acting force, and the inertia wheel 205 is driven to rotate;
In the above process, the flywheel 205 rotates to drive the rotating plate 212 to deflect, the lever structure formed by the rotating plate 212, the telescopic rod 213 and the rotating head 214 is utilized to drive the piston plate 209 to reciprocate by the linkage 211 and the piston rod 210 after the driving force is amplified, and the lifting plate 309 is driven to synchronously displace by the connecting rod 310, the radius of the lifting plate 309 is smaller than that of the piston plate 209, so as to further increase the pressure generated by the amplified driving force, the rotating wheel 302 is driven to rotate by hydraulic fluid, the rotating wheel 302 drives the flywheel 205 to rotate by the rotating shaft 303, the driving wheel 304, the shaft rod 305, the laminating wheel 306 and the driving belt 307, the amplified driving force is applied to the flywheel 205 again, so that the flywheel 205 obtains larger driving force, and further the cyclic superposition of the driving force is realized, so that the piston plate 209 obtains enough driving force to drive the cyclic flow of the trifluoromethane, and the core of the driving force is the temperature difference energy, so that the stability, the synchronism and the adaptability of greenhouse heating are greatly improved.
