Description

Technical Field

[0001] The invention relates to the technical field of heat pump thermal balance, and in particular to an energy-saving ground source heat pump thermal balance device. Background Art

[0002] A ground source heat pump is a system that uses shallow geothermal energy underground for heating and cooling. It is a clean, energy-saving, renewable energy technology that is widely used in residential, commercial buildings, and industrial fields. Ground source heat pumps use the constant temperature characteristics of the underground to use heat for heating in winter, which is a very efficient way of thermal management. The basic principle of a ground source heat pump is similar to that of an air source heat pump. It transfers heat from one place to another through the circulation of components such as compressors, evaporators, condensers, and expansion valves. In winter, a ground source heat pump obtains heat from the ground and transfers the heat to the building through a heat exchanger for heating. The temperature underground is almost constant when it reaches a certain depth, and heat is drawn from the ground in winter through an underground pipe system. Water or other fluid media circulates in the underground pipe system to bring the absorbed heat to the heat pump unit. Since the heat is taken from the ground, the heat provided may be unstable, so it is necessary to set up a ground source heat pump heat balance device; the ground source heat pump heat balance device in the prior art is mainly implemented by sensors and exchangers, which usually requires a cumbersome control system to implement, and since electronic components such as sensors are needed to monitor the thermal balance at all times, it is not conducive to energy saving.

[0009] The water in the heat exchange tank is heated by the heat exchange device, thereby heating the refrigerant in the inner coil. The compressor works, and the heated refrigerant in the heat exchange tank is transported to the refrigerant bottle through the compressor inlet pipe and the refrigerant inlet pipe. The refrigerant in the refrigerant bottle is then transported to the indoor exchanger through the refrigerant outlet pipe, and the indoor heat is supplied through the indoor exchanger. After the refrigerant is cooled, it returns to the inner coil in the heat exchange tank through the exchanger return pipe, absorbing the water in the heat exchange tank that provides heat through the heat exchange device, and this cycle repeats.

[0011] Furthermore, an electric heater is fixedly installed in the geothermal water storage heat exchange tank.

[0012] Water pump 1 transports the water that has absorbed heat in the heat exchange tank to the inlet pipe through the return cold water pipe. The cold water absorbs the heat from the ground source through the lower exchanger, and then returns to the hot water pipe through the outlet pipe. The heated water then enters the geothermal water storage heat exchange tank, and then the hot water enters the heat exchange tank through the hot water inlet pipe to provide heat for the inner coil in the heat exchange tank.

[0016] When the temperature in the geothermal water storage heat exchange tank is too low or too high, heat balance treatment is required. When the temperature in the geothermal water storage heat exchange tank is too high, the gas in the trigger cylinder expands, pushing the side piston and the side piston rod, thereby driving the side contact piece to move. When the side contact piece contacts the external contact head, the side contact piece pushes the external contact head and the external sliding column to slide, and the external spring connects the side contact piece and the two external contact heads. At this time, the two pump connecting lines are connected, and water pump 2 starts to work, and the water in the hot water balance tank passes through the compensation pipe and the return pipe to form a water circulation with the water in the lower inner coil in the geothermal water storage heat exchange tank, and part of the heat in the geothermal water storage heat exchange tank is taken away to the hot water balance tank, and the geothermal water storage heat exchange tank is heat balanced.

[0017] When the temperature in the geothermal water storage heat exchange tank is too low, the geothermal water storage heat exchange tank needs to be supplemented with heat. The gas in the trigger cylinder contracts, the side contact piece contacts the inner contact head, and the inner spring connects the side contact piece and the inner contact head. If the temperature in the hot water balance tank is sufficient, the gas in the temperature device cylinder expands and drives the inner piston and the contact rod to rise. The contact rod connects the two upper contact heads, thereby connecting the connecting wires, the pump wires and the series wires. At this time, the water pump 2 starts to work, and the hot water in the hot water balance tank passes through the compensation pipe and the return pipe to form a water circulation with the water in the lower inner coil in the geothermal water storage heat exchange tank, and the heat in the hot water balance tank is supplemented to the geothermal water storage heat exchange tank. If the temperature in the hot water balance tank is insufficient, the contact rod contacts the lower contact head, so that the two lower contact heads are connected, and the contact rod is separated from the upper contact head. At this time, the two heating wires are connected, and the electric heater starts to heat up, heating the water in the geothermal water storage heat exchange tank to achieve supplementary heat.

[0018] Compared with the prior art, the present invention has the following advantages: (1) The regulating device provided in the present invention can achieve thermal balance of the heat exchange device in a variety of different ways. When the temperature in the heat exchange device is too high, the heat energy is recovered into the heat balance tank for storage. When the temperature in the heat exchange device is too low, the geothermal water storage heat exchange tank is supplemented with heat by electric heating or heat balance water pipe, and the thermal balance effect is good. (2) The water tank thermometer provided in the present invention has two heating methods. When the temperature of the heat balance water tank is insufficient, the geothermal water storage heat exchange tank is supplemented with heat by electric heating. When the temperature of the heat balance water tank is sufficient, the heat in the heat balance water tank is added to the geothermal water storage heat exchange tank for heat supplement. (3) The thermal balance trigger and water tank thermometer provided in the present invention both sense the temperature change by the gas that expands due to heat, thereby judging whether thermal balance is required. The system has a high degree of automation and is energy-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] When the temperature in the geothermal water storage heat exchange tank 205 is too low or too high, heat balance treatment is required. When the temperature in the geothermal water storage heat exchange tank 205 is too high, the gas in the trigger cylinder 319 expands, pushing the side piston 320 and the side piston rod 321, thereby driving the side contact piece 322 to move. When the side contact piece 322 contacts the external contact head 323, the side contact piece 322 pushes the external contact head 323 and the external sliding column 324 to slide, and the external spring 325 makes the side contact piece 322 and the two external contact heads 323 connected. At this time, the two pump connecting lines 317 are connected, and the water pump 2 302 starts to work, and the water in the hot water balance tank 301 passes through the compensation pipe 303 and the return pipe 304, and forms a water circulation with the water in the lower inner coil 210 in the geothermal water storage heat exchange tank 205, and takes part of the heat in the geothermal water storage heat exchange tank 205 to the hot water balance tank 301, so as to perform heat balance on the geothermal water storage heat exchange tank 205.

[0048] When the temperature in the geothermal water storage heat exchange tank 205 is too low, it is necessary to supplement the heat for the geothermal water storage heat exchange tank 205, the gas in the trigger cylinder 319 contracts, the side contact piece 322 contacts the inner contact head 326, and the inner spring 328 connects the side contact piece 322 and the inner contact head 326; at this time, if the temperature in the hot water balance tank 301 is sufficient, the gas in the temperature device cylinder 305 expands and drives the inner piston 306 and the contact rod 307 to rise, and the contact rod 307 connects the two upper contact heads 308, so that the connecting wire 316, the pump wire 314 and the series wire 318 are connected, and the water pump 2 302 starts to work. The hot water in the hot water balance tank 301 passes through the compensation pipe 303 and the return pipe 304, and forms a water circulation with the water in the lower inner coil 210 in the geothermal water storage heat exchange tank 205, so that the heat in the hot water balance tank 301 is supplemented to the geothermal water storage heat exchange tank 205; at this time, if the temperature in the hot water balance tank 301 is insufficient, the contact rod 307 contacts the lower contact head 311, so that the two lower contact heads 311 are connected, and the contact rod 307 is disconnected from the upper contact head 308. At this time, the two heating wires 315 are connected, and the electric heater 211 starts to generate heat, so as to heat the water in the geothermal water storage heat exchange tank 205 and realize heat supplement.

[0049] The working principle of an energy-saving ground source heat pump heat balance device disclosed in the present invention is: the water in the heat exchange tank 106 is heated by the heat exchange device, thereby heating the refrigerant in the inner coil 112, the compressor 103 works, and the heated refrigerant in the heat exchange tank 106 is transported to the refrigerant bottle 104 through the compressor inlet pipe 109 and the refrigerant inlet pipe 107, and then the refrigerant in the refrigerant bottle 104 is transported to the indoor exchanger 111 through the refrigerant outlet pipe 108, and the indoor heat is supplied to the room through the indoor exchanger 111. Then, after the refrigerant is cooled, it returns to the inner coil 112 in the heat exchange tank 106 through the exchanger return pipe 110, and absorbs the water in the heat exchange tank 106 that provides heat through the heat exchange device, and this cycle is repeated. Water pump 1 201 transports the water in the heat exchange tank 106 that has absorbed heat through the return cold water pipe 207 to the inlet pipe 203 through the cold water pipe 209. The cold water absorbs the heat from the ground source through the lower exchanger 204, and then returns to the hot water pipe 208 through the outlet pipe 202. The heated water then enters the geothermal water storage heat exchange tank 205, and then the hot water enters the heat exchange tank 106 through the hot water inlet pipe 206 to provide heat for the inner coil 112 in the heat exchange tank 106.

[0050] When the temperature in the geothermal water storage heat exchange tank 205 is too low or too high, heat balance treatment is required. When the temperature in the geothermal water storage heat exchange tank 205 is too high, the gas in the trigger cylinder 319 expands, pushing the side piston 320 and the side piston rod 321, thereby driving the side contact piece 322 to move. When the side contact piece 322 contacts the external contact head 323, the side contact piece 322 pushes the external contact head 323 and the external sliding column 324 to slide, and the external spring 325 makes the side contact piece 322 and the two external contact heads 323 connected. At this time, the two pump connecting lines 317 are connected, and the water pump 2 302 starts to work, and the water in the hot water balance tank 301 passes through the compensation pipe 303 and the return pipe 304, and forms a water circulation with the water in the lower inner coil 210 in the geothermal water storage heat exchange tank 205, and takes part of the heat in the geothermal water storage heat exchange tank 205 to the hot water balance tank 301, so as to perform heat balance on the geothermal water storage heat exchange tank 205. When the temperature in the geothermal water storage heat exchange tank 205 is too low, it is necessary to supplement the heat for the geothermal water storage heat exchange tank 205, the gas in the trigger cylinder 319 contracts, the side contact piece 322 contacts the inner contact head 326, and the inner spring 328 connects the side contact piece 322 and the inner contact head 326; at this time, if the temperature in the hot water balance tank 301 is sufficient, the gas in the temperature device cylinder 305 expands and drives the inner piston 306 and the contact rod 307 to rise, and the contact rod 307 connects the two upper contact heads 308, so that the connecting wire 316, the pump wire 314 and the series wire 318 are connected, and the water pump 2 302 starts to work. The hot water in the hot water balance tank 301 passes through the compensation pipe 303 and the return pipe 304, and forms a water circulation with the water in the lower inner coil 210 in the geothermal water storage heat exchange tank 205, so that the heat in the hot water balance tank 301 is supplemented to the geothermal water storage heat exchange tank 205; at this time, if the temperature in the hot water balance tank 301 is insufficient, the contact rod 307 contacts the lower contact head 311, so that the two lower contact heads 311 are connected, and the contact rod 307 is disconnected from the upper contact head 308. At this time, the two heating wires 315 are connected, and the electric heater 211 starts to generate heat, so as to heat the water in the geothermal water storage heat exchange tank 205 and realize heat supplement.
