Description of the invention (5) Other details and features of the air conditioning system using the heat pump and the earth as a heat source in the present invention can be clearly understood by reading the embodiments described in detail below with reference to the accompanying drawings. [Embodiment] Fig. 1 is a schematic diagram of a first embodiment of an air-conditioning system using the earth as a heat source, in which an upper heat pump portion can be added or removed with a valve as needed to increase or decrease the working condition of the heat sink. Among them, the first heat pump 1 is a device included in the double straight line in the figure, but does not include the device included in the dotted line, including the first evaporator 16, the first compressor 1 2, the first condenser 1 7 And the first expansion valve 1 4, they are connected by pipes to form a heating loop circuit, wherein a steam cooling device 2 is connected in parallel in the circuit between the first evaporator 16, the expansion valve 14 and the compressor 12, FIG. The part surrounded by the dashed-dotted line, the steam cooling device 2 includes a second compressor 2, a steam cooler 22, and a second expansion valve 23. The steam cooler 22 is formed by coupling a second evaporator 25 and a second condenser 24 to each other. The evaporator 16 in the first heat pump 1 is coupled to the heat radiation coil 15 of the heat radiation circuit of the heat collection well 5. The liquid outlet of the first evaporator 16 is connected to the second compressor 21, the second condenser 24, the second expansion valve 23, and the liquid return end of the first evaporator 16 in sequence. In a loop circuit, the liquid outlet of the second evaporator 25 of the evaporator 2 2 and the first compressor 1 2, the first condenser 17, the first expansion valve 14 and the evaporator 2 2 The liquid return ends of the two evaporators 25 are sequentially connected into a loop circuit, and the heat exchange coils 18 on the energy output side are coupled to the first condenser 17 and connected to the heating user 7. So far, a system has been established between the low-level energy source and the heating user7, which is actually used by two heat pumps in series to jointly increase the secondary temperature, so that the low-level energy source can be used for heating.

1233477 V. Description of the invention (6) As shown in FIG. 1, it also includes a heat collecting well 5. A water supply pipe 51 and a return pipe 5 2 are provided in the heat collecting well 5, and a uniform flow is provided on the upper part of the water supply pipe 51. The current collector 5 3 is provided with a current collector 5 4 at the lower part of the water supply pipe 51. The current equalizer 5 3 and the current collector 54 are both perforated plates. A pebble 5 5 is filled between the well wall and the water supply pipe 51. The tube 51 and the return water tube 52 are respectively connected to the heat-dissipating coil 15 connected to the first evaporator 16 of the hot corn through the chestnut 56. When the pump 56 reduces the temperature of the water passing through the exothermic coil 15 coupled to the first evaporator 16 and sends it to the flow balancer 5 3, the water in the flow balancer 5 3 will evenly pass through the pebbles 5 in the well. 5 After absorbing heat, it reaches the collector 5 4 and then returns to the heat radiation coil 15 through the water supply pipe 5 1 in the center of the well, and releases heat to the first evaporator 16, so the heat is repeatedly sent to the first evaporator 1 repeatedly. 6. After the heat of the first evaporator 16 of the heat pump is obtained, the temperature is increased by the heat pump, and then the heat is released to the heating user 7 by the first condenser 17 to achieve the purpose of heating. The heat is continuously extracted, and the temperature of the pebble 5 5 will drop. The temperature is supplemented by the heat conduction of the soil 80. Due to the appearance of the heat pump of the present invention, the temperature of the pebble 55 can be reduced to about 30 ° C, and the heating purpose can still be achieved. The very low temperature of the pebble 55 will increase the local and overall temperature difference, that is, increase Speed of heat transfer, so that more heat can be extracted from the soil 80. An increase in the extracted heat means a lower output cost and a smaller footprint.

When the submersible pump 57 is in operation, the well water is sent to the heat exchanger 6 to release heat. After that, it is evenly passed through the pebble 55 by the flow equalizer 53 to absorb the heat, and the water that has absorbed the heat is sent to the diving chestnut again. The heat exchanger releases heat .... Repeat this cycle. The heat-extracted pebble 55 continues to replenish heat by exchanging heat with the groundwater flowing along the sandy layer 81, and finally reaches equilibrium at a certain temperature. In the above system, a plurality of valves can also be provided in the steam cooling device 2, so that the entire system can use the first heat pump to achieve heating when the energy used is higher than 5 ° C. When the energy source is lower than 5 ° C, the fluid steam heat pump of the present invention is used in two cases to achieve heating purposes.

1233477 V. Description of the invention (8) The fourth valve 34 is connected in series between the connection point of the three valves 33 and the liquid return end of the first evaporator 16.

When the first compressor 12 is started, the working medium in the first evaporator 16 absorbs the low-level energy flowing through the heat-dissipating coil 15 on the low-level energy input side and evaporates into gas, and the gas enters the first through the first valve 31 Compressor 1 2 compresses and warms up, and releases heat through condenser 17 to heat exchange coils 1 and 8 coupled to condenser 17 and then sends it to heating users 7 for heating purposes. The condensed liquid working fluid passes through expansion valve 1 4 Reduce the pressure and re-enter the first evaporator 16 through the third valve 33 to absorb heat ... Repeat this cycle. When the energy used is lower than 5 ° C, the first heat pump 1 cannot work normally, that is, when the amount of heat it raises is not sufficient for heating, the first heat pump 1 and the steam cooling device 2 work together to turn off the first Valve 3 1, third valve 3 3, open the second valve 3 2, the fourth valve 3 4. The first and second compressors 12 and 21 are started at the same time. At this time, two circuits work at the same time, that is, when the liquid below 5 ° C flows through the heat radiation coil 15 on the low energy input side, the evaporator 1 The working medium in 6 absorbs the low-level energy of the exothermic coil 15 and evaporates into a gas, which is compressed and warmed up by the second compressor 21 (about 15 ° C) and enters the second condenser 2 4 of the evaporator 2 4 The working medium is condensed in the condenser 24 to release heat to the working medium in the second evaporator 25 of the distiller 22, and the working medium absorbs the heat and evaporates into a gas, which is compressed and heated by the first compressor 12 and enters the first A condenser 17 condenses (about 50 ° C) to release heat, and releases the heat to the working medium of the heat exchanger coil 18 on the heating user side, and then sends it to the heating user 7 for heating. Steamer 2 in 2

Page 13 1233477 V. Description of the invention (9) The working medium in the second condenser 24 releases heat in the condenser 24 and is decompressed by the second expansion valve 23 and enters the first evaporator 16 to absorb heat and evaporate. Repeat this cycle. In the above system, four valves 4 0, 4 1, 4 2 are provided between the liquid return end of the heat release coil 15 on the low-level energy input side and the liquid return end of the heat exchange coil 18 on the output side. , 4 3, that is, the fifth to eighth valves, 4 valves 4 are also provided between the liquid discharge end of the heat radiation coil 15 on the low energy input side and the liquid discharge end of the heat exchange coil 18 on the output side 4 4, 4, 5, 4, 6, 47, that is, the ninth to twelfth valves. By switching these valves, the first heat pump or the steam cooler can work together for heating or cooling. The specific connection mode is: the liquid return end of the heat release coil 15 on the low energy input side is connected in series with a fifth valve 40, and the liquid return end of the heat exchange coil 1 8 on the output or heating user side is connected in series with an eighth valve 4 3, A sixth valve 41 is connected in parallel with the liquid inlet of valve 40 and the liquid outlet of valve 43, and a seventh valve 4 2 is connected in parallel with the liquid inlet of valve 43 and the liquid inlet of valve 43; The liquid discharge end of the exothermic coil 15 is connected in series with the twelfth valve 4 7, and the liquid discharge end of the heat exchange coil 18 on the output side is connected in series with the ninth valve 4 4, and the liquid discharge end of the valve 4 7 is connected to the valve 4 4 The inlet end of the valve is connected in parallel with the eleventh valve 46, and the tenth valve 45 is connected in parallel between the inlet end of the valve 47 and the outlet end of the valve 44. In this case, the working condition of the working medium in the heat pump loop circuit is the same as when there is no valve, so I won't repeat it here. The following describes the operation of the above-mentioned valves when the energy used is higher than 5 ° C and lower than 5 ° C, and when cooling and heating are converted: When the energy used is higher than 5 ° C for heating Only the first heat pump 1

1233477 V. Description of invention (ίο) Work, at this time, the first valve 3 1, the third valve 3 3, the second valve 3 2, the fourth valve 3 4, and the sixth valve 4 1 and the seventh valve 4 are closed at the same time. 2. The tenth valve 4 5, the eleventh valve 46, and the fifth valve 40, the eighth valve 4 3, the twelfth valve 4 7, and the ninth valve 44 are opened. The first compressor 12 is started for heating. When the energy used is below 5 ° C for heating, the first heat pump 1 and the steam cooling device 2 work together. At this time, the first valve 3 1 and the third valve 3 3 are closed, and the second valve 3 2 and the fourth are opened. Valve 3 4. Simultaneously close the sixth valve 41, the seventh valve 4, the tenth valve 4 5, the eleventh valve 4 6 and open the fifth valve 40, the eighth valve 4 3, the twelfth valve 4 7, and the ninth Valve 4 4. The first and second compressors 12 and 21 are started for heating. When cooling is needed in summer, just close valve 40, valve 4, 3, valve 4, 7, valve 4, open valve 4, valve 4, 2, valve 4, 5, and valve 4, and use the first heat pump 1 to run. At the same time, the heating user side is connected with the heat radiation coil 15 on the input side, and the heat exchange coil 18 on the heating user side is connected with the inlet and outlet liquid pipes on the input side. It can be seen from the running process that the fluid steam cooling heat pump system is a heat pump that changes the operating conditions to adapt to changes in outside air temperature. It can provide heating heat source temperature of different temperature according to the needs, which is mobile, flexible and widely applicable. The compressors of its two circuits can choose the same compressor or different compressors, and choose the best configuration according to different needs. In the above system, a heating pipe of the water heater 3 is connected in series between the first compressor 12 and the liquid return end of the condenser 17, and the working medium compressed and heated by the first compressor 12 passes through the heating pipe of the water heater 3 Heating domestic hot water

Page 15 1233477 V. Description of the invention (11) To the purpose of heating, domestic water has been heated for people to wash. Due to the different stratum structure, the flow velocity of groundwater is also different, that is to say, the heat supplied to the pebble 55 is different. Since the temperature of the pebble 55 of the air-conditioning system of the present invention can be balanced to 0 ° C, the entire system can be cooled in summer, heated in winter, and provided with hot water for daily life. In addition to the pebble filling, the artificial pebble 5 5 can also use other materials with large heat capacity, such as iron ore blocks, etc., to obtain a better condition.
