[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Please refer to Figures 1 to 4The multi-stage linkage system includes an outdoor main unit 1, an air-cooling unit 2 and a water-cooling unit 3; one side of the outdoor main unit 1 is provided with one or more air-cooling units 2, and the other side of the outdoor main unit 1 is provided with one or more water-cooling units 3; the air-cooling unit 2 includes an inner heat exchanger 21 and a thermostat 22, and one side of the inner heat exchanger 21 is connected to one side of the thermostat 22; the water-cooling unit 3 includes a water-fluorine heat exchanger 31, and one end of the water-fluorine heat exchanger 31 is connected to the air-cooling unit 2.

[0025] Based on the fact that multiple air-cooling units 2 are connected in parallel to the outdoor main unit 1, and multiple water-cooling units 3 are connected in parallel to the outdoor main unit 1, the outdoor main unit 1 can synchronously drive the operation of multiple groups of air-cooling units 2 and water-cooling units 3, thereby improving the compactness of the system structure arrangement.

[0026] Furthermore, the outdoor main unit 1 includes a four-way reversing valve 11; one side of the four-way reversing valve 11 is provided with a C port, an S port and an E port, and the other side of the four-way reversing valve 11 is provided with a D port.

[0027] Furthermore, the outdoor main unit 1 further includes a plate heat exchanger 12 and a compressor 13 , and one end of the plate heat exchanger 12 is connected to the compressor 13 .

[0028] Furthermore, a second fan 214 is disposed outside the inner heat exchanger 21 .

[0029] Specifically, when the machine is in heating mode, the compressor 13 outputs refrigerant. An oil separator 14 is provided on one side of the compressor 13. The refrigerant passes through the oil separator 14 to separate the lubricating oil in the refrigerant and recover it into the oil separator 14. After passing through the oil separator 14, the refrigerant flows into the D port of the four-way reversing valve 11 and exits from the E port. The refrigerant passes through the connected pipe and flows to the inner heat exchanger 21 of the air-cooled unit 2. The refrigerant is fully heat exchanged with the air driven by the second fan 214 in the inner heat exchanger 21, and the inner heat exchanger 21 delivers the heated air to the environment.

[0030] Furthermore, an electromagnetic two-way valve 15 connected to port D is provided at one end of the thermostat 22; a first filter 211 is provided at one end of the inner heat exchanger 21, a one-way valve 212 is provided at one end of the first filter 211, and a second filter 213 is provided at one end of the one-way valve 212.

[0031] Furthermore, the outdoor main unit 1 further comprises a drying filter 16, one end of which is connected to the C port.

[0032] Furthermore, the outdoor main unit 1 further includes an external heat exchanger 18, one end of which is connected to the C port.

[0033] Furthermore, the outdoor main unit 1 further includes a liquid storage tank 15 , and the liquid storage tank 15 is connected to the other end of the drying filter 16 .

[0034] Furthermore, one end of the compressor 13 is connected to the S port.

[0035] When the machine is in heating mode, the electromagnetic two-way valve 15 is in a closed state, and the refrigerant coming out of the inner heat exchanger 21 passes through the first filter 211, enters the one-way valve 212, and then passes through the second filter 213 and flows through the drying filter 16 to enter the liquid storage tank 15; at this time, the refrigerant is in a low-temperature state, and the proportion of liquid refrigerant is increased compared to the vapor refrigerant. A certain amount of residual refrigerant is stored in the liquid storage tank 15, which avoids the situation of insufficient refrigerant filling when the system volume remains unchanged.

[0036] Furthermore, a first fan 19 is disposed outside the outer heat exchanger 18 .

[0037] A third filter 151 is provided at one end of the liquid storage tank 15, and the refrigerant coming out of the liquid storage tank 15 passes through the third filter 151. Four connecting ports are provided on the plate heat exchanger 12, namely the first connecting port, the second connecting port, the third connecting port and the fourth connecting port. The refrigerant enters the first connecting port of the plate heat exchanger 12 from its main pipeline and exits from the second connecting port. A first electronic expansion valve 17 is provided at one end of the second connecting port. The refrigerant passing through the plate heat exchanger 12 enters the first electronic expansion valve 17 and is throttled into a vapor-liquid two-phase mixture. A fourth filter 171 is provided at one end of the first electronic expansion valve 17. The refrigerant flows through the fourth filter 171 and then enters the outer heat exchanger 18. The refrigerant then comes out of the outer heat exchanger 18 and passes through the C port of the four-way reversing valve 11, then flows out from the S port and enters the compressor 13, forming a cycle.

[0038] Specifically, when the machine is in heating mode, the refrigerant coming out of the liquid storage tank 15 passes through the third filter 151, and the refrigerant enters the first connection port of the plate heat exchanger 12 from its main pipeline, and exits from the second connection port. A second electronic expansion valve 121 is provided on one side of the fourth connection port of the plate heat exchanger 12. After part of the refrigerant passes through the second electronic expansion valve 121 and is divided into gas and liquid states, it passes through the fourth connection port and then exits from the third connection port. At this time, the refrigerant state in the pipeline connecting the fourth connection port and the third connection port is gas-liquid two-phase. The mixed low-temperature and low-pressure wet steam, and the refrigerant in the pipe connecting the first connection port and the second connection port is in a relatively high-temperature and high-pressure supercooled liquid state. The refrigerants on both sides exchange energy in the plate heat exchanger 12. The refrigerant in the pipe connecting the first connection port and the second connection port is further supercooled due to the release of heat. The refrigerant in the pipe connecting the fourth connection port and the third connection port evaporates into dry steam due to the absorption of heat. Finally, the refrigerant flows out of the third connection port and enters the compressor 13, so as to realize the refrigerant steam replenishment and achieve the effect of increasing enthalpy.

[0039] When the machine is in cooling mode, the compressor 13 outputs refrigerant, which is separated and recovered, enters port D, and exits from port C. After entering the outer heat exchanger 18 for sufficient heat exchange, it flows through the third filter 151 and enters the liquid storage tank 15. The refrigerant coming out of the liquid storage tank 15 flows through the drying filter 16 and passes through the second filter 213 along the pipeline. A third electronic expansion valve 215 is provided on one side of the second filter 213. The refrigerant enters the third electronic expansion valve 215 and is sent to the inner heat exchanger 21 after passing through the first filter 211. The refrigerant forms dry steam in the inner heat exchanger 21 due to its physical properties. The refrigerant absorbs the heat of the air in the inner heat exchanger 21, and the inner heat exchanger 21 sends low-temperature air to the outside.

[0040] The refrigerant absorbs the heat of the air in the inner heat exchanger 21. During this process, the flow rate of the refrigerant in the inner heat exchanger 21 is adjusted to reach a suitable dew point temperature. The refrigerant temperature is lower than the dew point temperature, thereby realizing the dehumidification function of the machine. Finally, the inner heat exchanger 21 outputs dry air.

[0041] The utility model provides a multi-stage linkage system. When the machine is in heating mode, the compressor 13 outputs refrigerant. After separation and recovery, the refrigerant enters the D port and exits from the C port. After entering the outer heat exchanger 18 for sufficient heat exchange, it flows through the third filter 151 and enters the liquid storage tank 15. The refrigerant coming out of the liquid storage tank 15 flows through the drying filter 16 and passes through the second filter 213 along the pipeline. A third electronic expansion valve 215 is provided on one side of the second filter 213. The refrigerant enters the third electronic expansion valve 215 and the first filter 211 and is sent into the inner heat exchanger 21. The refrigerant forms dry steam in the inner heat exchanger 21 due to its physical properties. The refrigerant absorbs the heat of the air in the inner heat exchanger 21 in the inner heat exchanger 21, and the inner heat exchanger 21 sends low-temperature air to the outside.
