The heat exchanger can have a plurality of working states, in one example, when the heat exchanger is used for refrigeration, the heat exchanger is essentially an evaporator, the temperature adjusting medium circulating in the heat exchanger is in a liquid state, and the temperature adjusting medium can exchange heat with an object to be temperature-adjusted through the heat exchanger, so that the temperature adjusting medium absorbs heat and is vaporized, and the purpose of refrigerating the object to be temperature-adjusted is achieved. In another example, when the heat exchanger is used for heating, the heat exchanger is substantially a condenser, the temperature adjusting medium circulating in the heat exchanger is in a gaseous state, and the temperature adjusting medium can pass through the heat exchanger to exchange heat with the object to be temperature adjusted, so that the temperature adjusting medium releases heat and is liquefied, and the purpose of heating the object to be temperature adjusted is achieved. In yet another example, the heat exchanger can be used for both cooling and heating, when the heat exchanger is used for cooling, the heat exchanger is used as an evaporator, when the heat exchanger is used for heating, the heat exchanger is used as a condenser, and the working principle when the heat exchanger is used as an evaporator or a condenser refers to the working principle of the evaporator and the condenser.

Referring to fig. 1, a schematic diagram of a related art air conditioning system for a vehicle is shown. As shown in fig. 1, the vehicle air conditioning system includes: a compressor 101, an exterior heat exchanger 102, a first electronic expansion valve 103, a second electronic expansion valve 104, an under-cabin heat exchanger 105, and a battery cold plate 106. One end of the compressor 101 is connected with one end of the external heat exchanger 102, the other end of the external heat exchanger 102 is connected with one end of the first electronic expansion valve 103, the other end of the first electronic expansion valve 103 is connected with one end of the cabin heat exchanger 105, the other end of the cabin heat exchanger 105 is connected with the other end of the compressor 101, the other end of the external heat exchanger 102 is connected with one end of the second electronic expansion valve 104, the other end of the second electronic expansion valve 104 is connected with one end of the battery cold plate 106, and the other end of the battery cold plate 106 is connected with the other end of the compressor 101.

Wherein one of one end and the other end of the compressor 101 has a suction function for sucking a refrigerant into the compressor, and the other of the one end and the other end of the compressor 101 has a discharge function for discharging the refrigerant from the compressor. And the cabin heat exchanger is used for adjusting the temperature of a passenger cabin of the vehicle, and the battery cold plate is used for adjusting the temperature of a battery in the vehicle.

The vehicle air conditioning system can be respectively used for refrigeration and heating, and the working principles of the vehicle air conditioning system and the vehicle air conditioning system are respectively introduced as follows:

when the vehicle air conditioning system is used for synchronously cooling the passenger compartment and the battery, the exterior heat exchanger 102 functions as a condenser, and the cabin interior heat exchanger 105 and the battery cooling plate 106 each function as an evaporator. At this time, the high-temperature and high-pressure gas refrigerant compressed by the compressor 101 first flows to the exterior heat exchanger 102, and the exterior heat exchanger 102 may convert the high-temperature and high-pressure gas refrigerant into a high-temperature and high-pressure liquid refrigerant and flow to the first electronic expansion valve 103 and the second electronic expansion valve 104, respectively. A part of the liquid refrigerant is throttled into a low-temperature low-pressure liquid refrigerant by the first electronic expansion valve 103, and flows to the cabin heat exchanger 105, and the low-temperature low-pressure liquid refrigerant is phase-changed into a low-temperature low-pressure gaseous refrigerant by the cabin heat exchanger 105, and absorbs heat in the phase change, so as to achieve the purpose of refrigerating by the cabin heat exchanger 105. Similarly, another part of the liquid refrigerant is throttled into a low-temperature low-pressure liquid refrigerant by the second electronic expansion valve 104 and flows to the battery cold plate 106, and the low-temperature low-pressure liquid refrigerant changes phase into a low-temperature low-pressure gaseous refrigerant by the battery cold plate 106 and absorbs heat in the phase change, so as to achieve the purpose of refrigerating through the battery cold plate 106. After flowing out of the cabin heat exchanger 105 and the battery cold plate 106, the refrigerant flows back to the compressor at the compressor suction pressure, completing the refrigerant cycle. At this time, the vehicle-mounted air conditioning system is provided with one condenser and two evaporators, and the purpose of refrigerating the battery is achieved through the battery cold plate, so that the system can also be called a one-to-two direct cooling vehicle thermal management system.

When the vehicle air conditioning system is used to simultaneously heat the passenger compartment and the battery, the exterior heat exchanger 102 functions as an evaporator, and the cabin heat exchanger 105 and the battery cold plate 106 both function as condensers. The high-temperature and high-pressure gaseous refrigerant compressed by the compressor 101 flows first to the cabin heat exchanger 105 and the battery cold plate 106. Under the action of the cabin heat exchanger 105, the high-temperature and high-pressure gaseous refrigerant flowing to the cabin heat exchanger 105 is phase-changed into a high-temperature and high-pressure liquid refrigerant, releases heat in the phase change of the refrigerant, and then flows toward the first electronic expansion valve 103. The first electronic expansion valve 103 throttles the high-temperature high-pressure liquid refrigerant into a low-temperature low-pressure liquid refrigerant. Under the action of the battery cold plate 106, the high-temperature and high-pressure gaseous refrigerant flowing to the battery cold plate 106 changes phase into a high-temperature and high-pressure liquid refrigerant, releases heat in the phase change of the refrigerant, and then flows to the second electronic expansion valve 104. The second electronic expansion valve 104 throttles the high-temperature high-pressure liquid refrigerant into a low-temperature low-pressure liquid refrigerant. The refrigerant flows out of each of the first electronic expansion valve 103 and the second electronic expansion valve 104 and then flows into the external heat exchanger 102, the external heat exchanger 102 changes the refrigerant into a low-temperature low-pressure gas refrigerant, and the gas refrigerant flows back to the compressor at the suction pressure of the compressor 101, completing the refrigerant cycle.

On the basis that the vehicle air conditioning system is used for synchronously refrigerating the passenger compartment and the battery, the vehicle air conditioning system can realize that the vehicle air conditioning system only refrigerates the passenger compartment by closing the first electronic expansion valve 103 and enabling the refrigerant to only flow through the heat exchanger 105 in the compartment, or the vehicle air conditioning system can realize that the vehicle air conditioning system only refrigerates the battery by closing the second electronic expansion valve 104 and enabling the refrigerant to only flow through the battery cold plate 106.

On the basis that the vehicle air conditioning system is used for synchronously heating the passenger compartment and the battery, the vehicle air conditioning system can only heat the passenger compartment by closing the first electronic expansion valve 103 and enabling the refrigerant to only flow through the heat exchanger 105 in the passenger compartment, or the vehicle air conditioning system can only heat the battery by closing the second electronic expansion valve 104 and enabling the refrigerant to only flow through the battery cold plate 106.

From the above, the vehicle air conditioning system can only heat or cool the passenger compartment independently, heat or cool the battery independently, heat the passenger compartment and the battery synchronously, or cool the passenger compartment and the battery synchronously, so that the working mode of the vehicle air conditioning system is single.

The embodiment of the application provides a temperature regulation system, has ten at least working modes, and it can be to a plurality of objects that wait to adjust the temperature carry out synchronous temperature regulation, also can be respectively to these a plurality of objects that wait to adjust the temperature carry out temperature regulation, has richened temperature regulation system's function, and has reduced temperature regulation system's cost effectively.

Referring to fig. 2, a temperature adjustment system provided in an embodiment of the present application is shown, where the temperature adjustment system includes: a first heat exchanger 201, a second heat exchanger 202, a third heat exchanger 203, a first reversing device 204 and a first switching device 205.

The first commutation device 204 has a first port a1, a second port b2, and a third port c 3.

The first heat exchanger 201 includes a first fluid passage having a first fluid port connected to the first port a1 of the first reversing device 204 and a second fluid port connected to the first junction point X.

The second heat exchanger 202 comprises a second fluid channel having a third fluid port connected to the second confluence point Y and a fourth fluid port connected to the first fluid port of the first heat exchanger 201. For example, the first heat exchanger and the second heat exchanger may each be a parallel flow heat exchanger, a plate heat exchanger, a double pipe heat exchanger, a fin and tube heat exchanger, or a shell and tube heat exchanger, etc.

The third heat exchanger 203 comprises a third fluid passage having a fifth fluid port connected to the second junction point Y by the first switching device 205 and a sixth fluid port also connected to the second port b2 of the first reversing device 204 and the sixth fluid port connected to the first junction point X and the third port c3 of the first reversing device 204, respectively. Illustratively, the third heat exchanger 203 may be a battery cold plate or a plate heat exchanger.

In the temperature regulation system, the circulation path of the temperature regulation medium may be one or more of:

when the first switching device 205 is turned on, in one circulation path, the temperature-adjusting medium flows between the second confluence point Y and the first confluence point X through the second fluid passage and the first fluid passage, and the temperature-adjusting medium flows from the second confluence point Y to the first confluence point X through the third fluid passage; in the other circulation path, the temperature adjusting medium passes through the first fluid passage, the second fluid passage and the third fluid passage in this order, and the circulation of the temperature adjusting medium is formed. The temperature adjusting medium may be a refrigerant (also referred to as a refrigerant).

When the first port and the second port of the first reversing device 204 are communicated, the temperature adjusting medium sequentially passes through the first fluid channel and the third fluid channel to form a circulation of the temperature adjusting medium, and the temperature adjusting medium can further sequentially pass through the first fluid channel and the second fluid channel from the first confluence point X to flow to the second confluence point Y.

When the first port a1 of the first reversing device 204 is communicated with the third port c3, and the first switching device 205 is turned on, the temperature-adjusting medium can flow from the first confluence point X to the second confluence point Y through the first fluid passage, the second fluid passage and the third fluid passage, respectively.

The first heat exchanger 201 and the second heat exchanger 202 are both used for exchanging heat with a first object to be temperature-regulated, and the third heat exchanger 203 is used for exchanging heat with a second object to be temperature-regulated.

In the temperature adjusting system, because the temperature adjusting medium can circulate according to various circulation paths, and the temperature adjusting medium has different temperature adjusting functions when according to different circulation paths, the temperature adjusting system can synchronously adjust the temperature of a plurality of objects to be adjusted, and can also respectively adjust the temperature of the plurality of objects to be adjusted, compared with the related technology, the function of the temperature adjusting system is enriched.

It should be noted that the temperature regulation system provided in the present application may be applied in a variety of environments. And the first object to be temperature-regulated and the second object to be temperature-regulated can be devices to be temperature-regulated or spaces to be temperature-regulated. For example, the first object to be temperature-regulated may be a space to be temperature-regulated, and the second object to be temperature-regulated may be a device to be temperature-regulated, which needs to be temperature-regulated. For example, when the temperature regulation system is used in a vehicle, the first object to be temperature-regulated and the second object to be temperature-regulated may be two devices in the vehicle, respectively, which need to be temperature-regulated. For example, when the vehicle is an aircraft, the first object to be temperature regulated may be a battery that powers the aircraft and the second object to be temperature regulated may be a passenger compartment of the aircraft. Alternatively, when the vehicle is a vehicle, the first object to be temperature regulated may be a battery that supplies power to the vehicle and the second object to be temperature regulated may be a passenger compartment of the vehicle. When the temperature of the passenger compartment is adjusted, the actual temperature adjustment target is usually a space inside the passenger compartment. The temperature regulating system will be described below by taking the first object to be temperature regulated as the passenger compartment of the vehicle and the second object to be temperature regulated as the battery of the vehicle as an example.

Optionally, fig. 3 is a schematic structural diagram of another temperature adjustment system provided in an embodiment of the present application. As shown in fig. 3, the temperature adjusting system may further include: the compression device 206, the compression device 206 being in communication with the second fluid port of the first heat exchanger 201 and the first confluence point X, respectively. Illustratively, the compression device 206 may be a compressor.

The compressing device may include a proportional-integral-derivative (PID) controller, a motor, a piston, an air suction pipe, and an air discharge pipe. Compressor arrangement can inhale temperature regulation medium through the breathing pipe, then drives the piston through the motor to compress temperature regulation medium, make this temperature regulation medium compressed into high temperature high pressure and be gaseous temperature regulation medium, then the blast pipe through compressor arrangement exports this high temperature high pressure temperature regulation medium. Optionally, the compressing device may further include: and the proportion-integration-differentiation (PID) controller is used for controlling the rotating speed of the motor and further controlling the flow of the temperature regulating medium in the temperature regulating system.

Further, with continued reference to fig. 3, the temperature adjustment system further includes: a third commutation device 207. The third reversing device 207 has a seventh port g7, an eighth port h8, a ninth port i9 and a tenth port j10, the seventh port g7 being in communication with one gas delivery nozzle of the compression device 206, the eighth port h8 being in communication with the second fluid port of the first heat exchanger 201, the ninth port i9 being in communication with another gas delivery nozzle of the compression device 206, the tenth port j10 being in communication with the first confluence point X.

When the seventh port g7 is communicated with the eighth port h8, and the ninth port i9 is communicated with the tenth port j10, the communicated seventh port g7 and eighth port h8 are communicated from the eighth port h8 to the seventh port g7, and the communicated ninth port i9 and tenth port j10 are communicated from the ninth port i9 to the tenth port j 10. This allows the temperature-adjusting medium flowing out of the second fluid port to flow to the seventh port g7 through the eighth port h8 of the third direction changing device 207 and thus to one gas pipe port of the compression device 206, and after flowing out of the other gas pipe port of the compression device 206, to flow to the tenth port j10 through the ninth port i9 of the third direction changing device 207 and thus to the first confluence point X.

When the seventh port g7 communicates with the tenth port j10 and the ninth port i9 communicates with the eighth port h8, the communication direction between the communicated seventh port g7 and the tenth port j10 is from the tenth port j10 to the seventh port g7, and the communication direction between the communicated ninth port i9 and the eighth port h8 is from the ninth port i9 to the eighth port h 8. This allows the temperature-adjusting medium flowing out of the first confluence point X to flow to the seventh port g7 through the tenth port j10 of the third direction changing device 207, to flow to one gas pipe port of the compression device 206, to flow to the eighth port h8 through the ninth port i9 of the third direction changing device 207, and to flow to the first heat exchanger 201 through the eighth port h8 after flowing out of the other gas pipe port of the compression device 206. Illustratively, the third direction changing device 207 may be a four-way direction changing valve. Alternatively, the third reversing device can be other types of valves.

Optionally, a moisture absorbent (also called a desiccant) may be disposed in at least one of the first heat exchanger 201 and the second heat exchanger 202. The moisture absorbent has adsorption capacity and can absorb moisture in fluid flowing through the moisture absorbent so as to achieve the effect of moisture absorption. For example, the first heat exchanger 201 and the second heat exchanger 202 may each be provided with a moisture absorbent, and the moisture absorbent may dry (i.e., dehumidify) the first object to be temperature-regulated to reduce the moisture load in the temperature regulation system.

For example, the moisture absorbent may be a solid type moisture absorbent, and in this case, the moisture absorbent may be coated on the surface of the heat exchanger. Alternatively, a dehumidifying rotary disk coated with a moisture absorbent may be provided in the heat exchanger. The dehumidifying rotary disc can rotate in the heat exchanger, and the dehumidifying rotary disc can be a cylindrical rotary disc, and the surface of the rotary disc is in a honeycomb shape. Alternatively, the moisture absorbent may be a liquid type moisture absorbent, and in this case, a moisture absorbent container in which the moisture absorbent is placed is disposed in the heat exchanger.

In the related art, when an object to be temperature-regulated is dehumidified, a heat exchanger is generally used as an evaporator to refrigerate the object to be temperature-regulated, so that water vapor in air flowing through the object to be temperature-regulated is condensed and separated out in the form of condensed water, and the purpose of dehumidifying the object to be temperature-regulated is achieved. Since the cabin heat exchanger for temperature regulation of the passenger cabin and the battery cold plate for temperature regulation of the battery are generally connected in parallel, when the passenger cabin and the battery are cooled simultaneously, the actual evaporation temperatures of the cabin heat exchanger and the battery cold plate are the same. However, when the passenger compartment is usually refrigerated, the cool air generated by the heat exchanger in the compartment is used for dehumidifying the passenger compartment and refrigerating the passenger compartment, and the cool air generated by the battery cold plate is only used for refrigerating, so the target evaporation temperature of the heat exchanger in the compartment is lower than the target evaporation temperature of the battery cold plate, and the target evaporation temperature of the heat exchanger in the compartment is different from the target evaporation temperature of the battery cold plate; the target evaporation temperature of the battery cold plate refers to the evaporation temperature at which the battery refrigeration requirement is met. However, since the refrigerant directly collects to the air suction port of the compressor after passing through the in-cabin evaporator and the battery cold plate, the air suction pressure of the temperature regulation system is determined by the lowest evaporation pressure of the temperature regulation system, and the evaporation pressure is in direct proportion to the evaporation temperature, the actual evaporation temperature of the battery cold plate is lower than the target evaporation temperature of the battery cold plate, so that the refrigerating capacity of the battery is insufficient, and the temperature of the battery deviates from the reference temperature interval. Therefore, in the related art, it is necessary to reduce the pressure on the outlet side of the battery cold plate by increasing the evaporation pressure of the battery cold plate (i.e., increasing the evaporation temperature of the battery cold plate) and using a pressure relief device on the outlet side of the battery cold plate, so that the evaporation pressure of the battery cold plate after pressure reduction is the same as the evaporation pressure of the cabin heat exchanger, and thus the cabin heat exchanger and the battery cold plate are both in a normal refrigeration state, and the temperatures of the cabin heat exchanger and the battery cold plate are ensured. However, this results in a less efficient temperature regulation due to the pressure reduction by the pressure relief device.

In the embodiment of the application, because dispose the desiccator in the heat exchanger, can adopt the adsorption of this desiccator to dehumidify, compare in correlation technique, need not to refrigerate through the heat exchanger and just can realize the dehumidification function, can be used for the refrigeration with whole air conditioning of heat exchanger promptly, in order to improve the evaporating temperature of heat exchanger, the difference of the actual evaporating temperature between the heat exchanger that the object that waits to adjust the temperature to first object and the second that waits to adjust the temperature carries out temperature regulation has been reduced, thereby avoid adopting pressure relief device, also can make first object that waits to adjust the temperature and the second object that waits to adjust the temperature all be in normal refrigeration state as far as possible, the temperature regulation efficiency of temperature regulation system has been improved.

Optionally, as shown in fig. 3, the temperature adjustment system further includes: a first throttle device 208, which first throttle device 208 is arranged between the fourth fluid port of the second heat exchanger 202 and the first fluid port of the first heat exchanger 201. The first throttle device 208 has a throttling effect. When the first throttle device 208 is opened, the pressure of the temperature-regulating medium flowing into the first throttle device 208 is different from the pressure of the temperature-regulating medium flowing out of the first throttle device 208 by the throttling action of the first throttle device 208. The first heat exchanger 201 may be used as one of a condenser and an evaporator, and the second heat exchanger 202 as the other of the condenser and the evaporator, by the temperature adjusting media of different pressures.

For example, when the first throttling device 208 is turned on, if the temperature adjusting medium flows from the first heat exchanger 201 to the second heat exchanger 202 through the first throttling device 208, the pressure of the temperature adjusting medium flowing into the second heat exchanger 202 is lower than the pressure of the temperature adjusting medium flowing into the first heat exchanger 201, and at this time, the first heat exchanger 201 may be used as a condenser to heat the first object to be temperature-adjusted, and the second heat exchanger 202 may be used as an evaporator to dehumidify the object to be dehumidified at a higher evaporation temperature. For example, the object to be dehumidified may be wind flowing into the first heat exchanger 201, and the wind is used for exchanging heat with the temperature adjusting medium in the first heat exchanger 201, so as to adjust the temperature of the first object to be temperature-adjusted.

Alternatively, when the first throttling device 208 is opened, if the temperature regulation medium flows from the second heat exchanger 202 to the first heat exchanger 201 through the first throttling device 208, the pressure of the temperature regulation medium flowing into the first heat exchanger 201 is lower than the pressure of the temperature regulation medium flowing into the second heat exchanger 202, at this time, the first heat exchanger 201 may be used as an evaporator to refrigerate the first object to be temperature-regulated, and the second heat exchanger 202 may be used as a condenser to dehumidify the desiccant, that is, the second heat exchanger 202 is in the desiccant regeneration mode.

Optionally, with continuing reference to fig. 3, the temperature adjustment system may further include: and a second switching device 209 connected in parallel with the first throttling element 208, wherein when the first throttling element 208 is opened, the second switching device 209 is closed. When the second switching device 209 is turned on, the first throttling device 208 is turned off. When the second switching device 209 is turned on, since the resistance of the second switching device 209 to the temperature adjustment medium is small, the pressures of the temperature adjustment media flowing into the first heat exchanger 201 and the second heat exchanger 202 are approximately equal, so that the first heat exchanger 201 and the second heat exchanger 202 can both function as a condenser or both function as an evaporator. For example, the first heat exchanger and the second heat exchanger are both used as condensers, the first heat exchanger is used for heating the first object to be temperature-regulated, and the second heat exchanger is used for dehumidifying the moisture absorbent coated on the surface of the first object to be temperature-regulated, so that the moisture absorbent is regenerated.

Optionally, with continuing reference to fig. 3, the temperature regulation system may further include: a second throttling device 210 arranged between the first switching device 205 and a fifth fluid port of the third heat exchanger 203. The second throttle means 210 has a throttling effect. When the second throttle device 210 is opened, the pressure of the temperature regulation medium flowing into the second throttle device 210 is different from the pressure of the temperature regulation medium flowing out of the second throttle device 210 by the throttling action of the second throttle device 210, so that one of the two heat exchangers located at both ends of the second throttle device 210 can be used as an evaporator and the other as a condenser by the temperature regulation medium of different pressures. That is, one of the second heat exchanger 202 and the third heat exchanger 203 may function as an evaporator, and the other may function as a condenser. Accordingly, the third heat exchanger may function as a condenser and an evaporator, respectively, under different flow paths.

For example, when the second throttle device 210 is opened, if the temperature regulating medium flows from the first heat exchanger 201 to the third heat exchanger 203 through the second throttle device 210, the pressure of the temperature regulating medium flowing into the third heat exchanger 203 is lower than the pressure of the temperature regulating medium flowing into the first heat exchanger 201, and at this time, the first heat exchanger 201 can be used as a condenser to heat the first temperature object, and the third heat exchanger 203 can be used as an evaporator to cool the second temperature object.

Optionally, with continued reference to fig. 3, the temperature adjustment system further includes: and a second reversing device 211, the second reversing device 211 having a fourth port d4, a fifth port e5 and a sixth port f6, the fourth port d4 being in communication with the sixth fluid port of the third heat exchanger 203, the fifth port e5 being in communication with the third port c3 of the first reversing device 204 and the first junction point X, respectively, and the sixth port f6 being in communication with the first junction point X.

For example, when the fourth port d4 is communicated with the fifth port e5, the temperature adjusting medium flowing out of the second fluid port of the first heat exchanger 201 and the temperature adjusting medium flowing out of the sixth fluid port of the third heat exchanger 203 can flow through the third direction changing device 207 to the compression device 206. Alternatively, the temperature adjusting medium flowing out of the compression device 206 may flow to the second fluid port of the first heat exchanger 201 and the sixth fluid port of the third heat exchanger 203, respectively, through the third reversing device 207. When the fourth port d4 is communicated with the sixth port f6, the temperature adjusting medium flowing out of the sixth fluid port of the third heat exchanger 203 can flow to the first confluence point X.

Optionally, with continued reference to fig. 3, the temperature adjustment system further includes: a fourth switching device 212 and a fourth heat exchanger 213 connected in series between the second merging point Y and the first merging point X, and the fourth switching device 212 is turned off while the temperature-adjusting medium sequentially flows through the first fluid passage of the first heat exchanger 201, the second fluid passage of the second heat exchanger 202, and the third fluid passage of the third heat exchanger 203.

The fourth heat exchanger 213 may function as a condenser when the temperature adjusting medium from the compression device flows to the third heat exchanger 203 and the first heat exchanger 201 through the fourth heat exchanger 213, respectively. The fourth heat exchanger 213 functions as an evaporator when the temperature adjusting medium from the compression device flows through the first heat exchanger 201 to the second heat exchanger 202 and the third heat exchanger 203, respectively, and then flows through the fourth heat exchanger 213 to the compression device 206.

Optionally, the temperature regulation system further comprises: a third throttling device 214 is arranged between the third fluid port of the second heat exchanger 202 and the second junction point Y. The third throttle device 214 has a throttling effect. When the third throttling device 214 is opened, the pressure of the temperature adjusting medium flowing into the third throttling device 214 is different from the pressure of the temperature adjusting medium flowing out of the third throttling device 214 by the throttling action of the third throttling device 214. One of the second heat exchanger 202 and the fourth heat exchanger 213 located at both ends of the third throttling member 214 may function as an evaporator and the other as a condenser under the influence of the temperature-regulating media of different pressures. Alternatively, both the second heat exchanger 202 and the fourth heat exchanger 213 may be used as evaporators, but the evaporation temperatures of the two are different.

For example, when the third throttling device 214 is turned on, if the temperature adjusting medium flows from the second heat exchanger 202 to the fourth heat exchanger 213 through the third throttling device 214, the pressure of the temperature adjusting medium flowing into the fourth heat exchanger 213 is lower than the pressure of the temperature adjusting medium flowing into the second heat exchanger 202. At this time, the second heat exchanger 202 may function as a condenser and the fourth heat exchanger 213 may function as an evaporator, or both the second heat exchanger 202 and the fourth heat exchanger 213 may function as evaporators, but the evaporation temperature of the second heat exchanger 202 is higher than that of the fourth heat exchanger 213.

Further, with continued reference to fig. 3, the temperature adjustment system further includes: and a third switching device 215 connected in parallel with the third current-regulating device 214, and when the third current-regulating device 214 is turned on, the third switching device 215 is turned off. When the third switching device 215 is turned on, the third current-regulating device 214 is turned off. When the third switching device 215 is turned on, since the resistance of the third switching device 215 to the temperature regulation medium is small, the pressures of the temperature regulation medium flowing into the second heat exchanger 202 and the fourth heat exchanger 213 are approximately equalized, so that the second heat exchanger 202 and the fourth heat exchanger 213 can both function as a condenser or both function as an evaporator. For example, when the third switching device 215 is turned on, the second heat exchanger 202 and the fourth heat exchanger 213 may both be condensers.

Optionally, fig. 4 is a schematic structural diagram of a part of a temperature adjustment system provided in an embodiment of the present application. As shown in fig. 4, the temperature adjusting system may further include: the air box 216 has an air cavity, two air ducts 2161, and a first air outlet (also called a Supply Air (SA) port) 2162. The first air outlet 2162 is configured to blow air toward the first object to be temperature-regulated. For example, when the first object to be temperature-regulated is a chamber to be temperature-regulated, the first outlet port 2162 is configured to communicate with the interior of the chamber to be temperature-regulated. And each air duct 2161 is used for supplying air into the air cavity, i.e. each air duct has an air inlet.

The first heat exchanger 201 and the second heat exchanger 202 are respectively located at the air outlets of the two air ducts 2161, and at least one of the first heat exchanger 201 and the second heat exchanger 202 is located at the outer side of the air outlet.

Accordingly, the first inner damper 217 is configured to: when the first heat exchanger and the second heat exchanger are used for adjusting the temperature of the chamber to be temperature-adjusted, the first heat exchanger and the second heat exchanger are connected with the outer wall of one heat exchanger located on the outer side of the air outlet of the air duct and the air box wall located on one side, far away from the one heat exchanger, of the other heat exchanger, so that air from the air outlet side of the other heat exchanger enters the air cavity through the one heat exchanger.

Illustratively, as shown in fig. 4, the first heat exchanger 201 is located outside the air outlet of the air duct, and the second heat exchanger 202 is located at the air outlet of the air duct. When the first heat exchanger and the second heat exchanger are both used for adjusting the temperature of the chamber to be adjusted in temperature, the first inner air door 217 is connected with the outer wall of the first heat exchanger 201 and the air box wall of one side, far away from the first heat exchanger, of the second heat exchanger 202, so that air from the air outlet side of the second heat exchanger 202 is subjected to air cavity through the first heat exchanger 201. The dotted line with arrows in fig. 4 indicates the direction of wind flow.

Further, first interior air door 217 can have two pages of door leaves, and these two pages of door leaves and same rotation axis fixed connection, this rotation axis can with the outer wall fixed connection of a heat exchanger, and the one end homoenergetic that its rotation axis was kept away from to every page of door leaf all can be connected with the bellows wall, and these two pages of door leaves can be followed the rotation axis and realized 360 degrees rotations. For example, in fig. 4, one end of one door leaf far away from the rotating shaft is connected with the air box wall between the two air ducts, and one end of the other door leaf far away from the rotating shaft is connected with the air box wall on the side of the second heat exchanger far away from the first heat exchanger.

Because the first inner air door can enable the air from the air outlet side of the second heat exchanger to enter the air cavity through the first heat exchanger, when the first heat exchanger is used as a condenser and the second heat exchanger is used as an evaporator, the second heat exchanger can firstly dehumidify the air entering the second heat exchanger, and the first heat exchanger heats the dehumidified air, so that the condition that the hot air with higher moisture content is sent into the chamber to be temperature-regulated is avoided, and a large amount of condensed water is generated after the hot air meets the cold condition. Further, when the temperature regulating system is a vehicle-mounted temperature regulating system, the situation that hot air with high moisture content is fed into the passenger compartment to cause the fog of the hot air on the window with low temperature and the driving safety is influenced can be avoided.

Further, as shown in fig. 4, each air duct 2161 may also have a circulation damper 218, and the circulation damper 218 may have a first connection state P and a second connection state Q. When the circulating damper 218 of the air duct is in the first connection state P, the air inlet of the air duct 2161 is communicated with the outside of the chamber to be temperature-regulated, so that the air entering the air cavity from the air duct 2161 is fresh air from the outside of the chamber to be temperature-regulated, and at this time, the air inlet may be referred to as an air inlet (OA) port. When the circulating air door 218 of the air duct is in the second connection state Q, the air inlet of the air duct 2161 is communicated with the inside of the chamber to be temperature-regulated, so that the air entering the air cavity from the air duct 2161 is the return air from the inside of the chamber to be temperature-regulated, and at this time, the air inlet may be referred to as a Return Air (RA) port.

Further, as shown in fig. 5, at least one of the first heat exchanger 201 and the second heat exchanger 202 is provided with a moisture absorbent, and the temperature adjustment system may further include: the second inner damper 219 and the bellows 216 further have a second air outlet (also called an exhaust air outlet, EA), and the second inner damper 219 is located inside the second air outlet, and the second air outlet is communicated with the outside of the chamber to be temperature-adjusted.

The first inner damper 217 is further configured to: the target air duct is isolated from the air cavity, the heat exchangers at the air outlet of the target air duct, the second air outlet and the target air duct are all located on the same side of the first inner air door, a moisture absorbent is configured in the heat exchanger at the air outlet of the target air duct, and the heat exchanger at the air outlet of the target air duct is used for dehumidifying the moisture absorbent.

Wherein the second inner damper 219 is configured to: when the target air duct is isolated from the air cavity, and the target air duct, the second air outlet and the heat exchanger at the air outlet of the target air duct are all positioned at the same side of the first inner air door, the second air outlet is exposed, and when the two air ducts are communicated with the air cavity, the second air outlet is sealed.

Also, when the second inner damper 219 is exposed out of the second air outlet, the circulating damper 218 on the target air duct may be in the first connection state P, so that the air flowing through the heat exchanger 202 at the air outlet of the target air duct may be fresh air. Because the fresh air humidity is usually lower, the moisture in the air can be prevented from being absorbed again by the moisture absorbent, and the regeneration efficiency of the moisture absorbent is further improved.

Optionally, with continuing reference to fig. 5, the temperature adjustment system further includes: two blowers 220, the two blowers 220 are respectively arranged at the air inlets of the two air channels 2161, the blowers 220 are configured to adjust the pressure difference between the inner side and the outer side of the air inlets, thereby adjusting the air volume entering the two air channels 2161. Because the air inlet of each air channel is provided with the air blower, the rotating speed of the air blower can be controlled according to requirements so as to adjust the air quantity entering the air channels.

Referring to fig. 6, when the first object to be temperature-regulated is a passenger compartment, the temperature regulating system may have three first air outlets, and each first air outlet is configured with an air supply door 221. One first air outlet of the three first air outlets is used for supplying air to a front seat where the driving position of the passenger compartment is located, the first air outlet is further communicated with three air supply pipelines P1-P3, and the three air supply pipelines P1-P3 are respectively used for supplying air to the left side, the middle and the right side of the front seat where the driving position is located. The other two first air outlets in the three first air outlets are respectively used for supplying air to the left side position and the rear right side position behind the driving position.

The following describes the operation mode of the temperature adjustment system provided in the embodiment of the present application, with reference to fig. 7 to 21, by taking the temperature adjustment system shown in fig. 3 as an example:

a first mode of operation: and in the first cooling mode, the first object to be cooled is cooled, and the second object to be cooled is cooled.

Fig. 7 shows the circulation path of the temperature adjusting medium in this mode (as indicated by the thick solid line in fig. 7), and the conduction states and communication manners of the respective devices in the temperature adjusting system. As shown in fig. 7, in this operating mode, the fourth switching device 212 is conducting, the third switching device 215 is conducting, the first throttling means 208 is open, the first switching device 205 is conducting, the second throttling means 210 is open, the fourth port d4 of the second commutation device 211 communicates with the fifth port e5, and the seventh port g7 of the third commutation device 207 communicates with the eighth port h8, and the ninth port i9 of the third commutation device 207 communicates with the tenth port j 10.

In this operation mode, the temperature adjusting medium compressed by the compression device 206 flows through the ninth port i9, the tenth port j10, the fourth heat exchanger 213 and the fourth switching device 212 in sequence from the other gas pipe of the compression device 206. After passing through the third switching device 215, a part of the temperature adjusting medium flowing out of the fourth switching device 212 passes through the second heat exchanger 202, the first throttling element 208 and the first heat exchanger 201 in this order, and flows to the eighth port h8 of the third reversing device 207. And, another part of the temperature adjusting medium flowing out from the fourth switching device 212 flows through the first switching device 205, then sequentially passes through the second throttling device 210, the third heat exchanger 203 flows to the fourth port d4 of the second reversing device 211, and then flows to the eighth port h8 of the third reversing device 207 from the fifth port e5 of the second reversing device 211. The temperature adjusting medium flowing through the eighth port h8 flows back to the compression device 206 through the seventh port g7 via the ninth port i9 and the tenth port j10, completing the temperature adjusting medium circulation.

During this cycle, the temperature adjusting medium from the compression device flows into the fourth heat exchanger 213 first, and at this time, the fourth heat exchanger 213 serves as a condenser. Then to the third switching device 215 and the first switching device 205, respectively. On the one hand, the second heat exchanger 202 functions as a condenser since the pressure of the temperature adjusting medium is substantially equal before and after flowing through the third switching device 215. The temperature adjusting medium releases heat when flowing through the second heat exchanger 202, so that the second heat exchanger 202 can dehumidify the moisture absorbent in the second heat exchanger 202 by using fresh air, thereby realizing regeneration of the moisture absorbent. After that, the temperature regulating medium flows to the first throttling device 208, and under the throttling action of the first throttling device 208, the pressure of the temperature regulating medium flowing into the first throttling device 208 is higher than the pressure of the temperature regulating medium flowing into the first heat exchanger 201, so that the first heat exchanger 201 functions as an evaporator, and absorbs heat when the temperature regulating medium flows through the first heat exchanger 201 to refrigerate the first object to be temperature regulated. On the other hand, after the temperature adjusting medium flows to the second throttling device 210 through the first switching device 205, under the throttling action of the second throttling device 210, the pressure of the temperature adjusting medium flowing into the second throttling device 210 is higher than that of the temperature adjusting medium flowing into the third heat exchanger 203, so that the third heat exchanger 203 is used as an evaporator, and absorbs heat when the temperature adjusting medium flows through the third heat exchanger 203 to refrigerate the second object to be temperature adjusted.

Fig. 6 shows states of the first inner damper and the second inner damper in the first simultaneous cooling mode, as shown in fig. 6 and 7, the first inner damper isolates the air duct where the second heat exchanger is located from the air cavity, the air duct, the second air outlet and the second heat exchanger are all located on the same side of the first inner damper, and the second inner damper exposes the second air outlet. At this time, the circulating air doors on the two air ducts can be both in the first connection state P, so that fresh air flows into the air duct from the OA port of the air duct where the first heat exchanger 201 is located, and flows into the interior of the first object to be temperature-regulated (or the chamber to be temperature-regulated) from the SA port after entering the air chamber through the first heat exchanger 201, thereby refrigerating the first object to be temperature-regulated; and fresh air enters the air duct from the OA port of the air duct where the second heat exchanger 202 is located, and after passing through the second heat exchanger 202, flows to the outside of the first object to be temperature-regulated from the EA port, so that the desiccant regeneration is realized.

The second working mode is as follows: and in the second cooling mode, the first object to be cooled is cooled, and the second object to be cooled is cooled.

Fig. 8 shows the circulation path of the temperature adjusting medium in this mode (as indicated by the thick solid line in fig. 8), and the conduction states and communication manners of the respective devices in the temperature adjusting system. As shown in fig. 8, in this operating mode, first throttling device 208 is open, third switching device 215 is conductive, fourth switching device 212 is conductive, first port a1 of first commutation device 204 is in communication with second port b2, second throttling device 210 is open, fourth port d4 and sixth port f6 of second commutation device 211 are in communication, and seventh port g7 of third commutation device 207 is in communication with tenth port j10, and eighth port h8 is in communication with ninth port i 9.

In this operation mode, the temperature adjusting medium is compressed by the compression device 206, and then discharged from another gas pipe of the compression device 206, and flows through the ninth port i9 of the third direction changing device 207, the eighth port h8 of the third direction changing device 207, and the first heat exchanger 201 in sequence. After flowing out of the first heat exchanger 201, a part of the temperature adjusting medium flows through the first throttling device 208, the second heat exchanger 202, the third switching device 215, the fourth switching device 212, the fourth heat exchanger 213, and the tenth port j10 of the third reversing device 207 in this order. Another portion of the temperature adjusting medium flowing from the first heat exchanger 201 flows through the first port a1 of the first reversing device 204, the second port b2 of the first reversing device 204, the second throttling device 210, the third heat exchanger 203, the fourth port d4 and the sixth port f6 of the second reversing device 211, and flows to the tenth port j10 of the third reversing device 207 in this order. The temperature adjusting medium flowing through the tenth port j10 flows back to the compression device 206 through the seventh port g7, and the temperature adjusting medium circulation is completed.

In the cycle, after flowing out of the compression device, the temperature adjusting medium flows to the fourth heat exchanger 213 after flowing through the first heat exchanger 201 and the second heat exchanger 202, so that the first heat exchanger 201 serves as a condenser, and the temperature adjusting medium releases heat when flowing through the first heat exchanger 201, so that the first heat exchanger 201 can utilize fresh air to dehumidify the moisture absorbent in the first heat exchanger 201, thereby realizing regeneration of the moisture absorbent. The fourth heat exchanger 213 serves as an evaporator. And since the first throttling device 208 is opened in the process, the pressure of the temperature regulation medium flowing into the first heat exchanger 201 is higher than the pressure of the temperature regulation medium flowing into the second heat exchanger 202, so that the second heat exchanger 202 functions as an evaporator, and the temperature regulation medium absorbs heat when flowing through the second heat exchanger 202 to refrigerate the first object to be temperature regulated. And, since the second throttling device 210 is opened in this process, the pressure of the temperature regulation medium flowing into the first heat exchanger 201 is greater than the pressure of the temperature regulation medium flowing into the third heat exchanger 203, so that the third heat exchanger 203 functions as an evaporator, and the temperature regulation medium absorbs heat while flowing through the third heat exchanger 203 to refrigerate the second object to be temperature-regulated.

Fig. 9 shows the states of the first inner damper and the second inner damper in the second simultaneous cooling mode, as shown in fig. 9, the first inner damper 217 separates the air duct in which the first heat exchanger 201 is located from the air chamber, and the air duct, the second air outlet and the first heat exchanger are all located on the same side of the first inner damper 217, and the second inner damper 219 exposes the second air outlet. At this time, the circulating air doors on the two air ducts can be both in the first connection state P, so that fresh air flows into the air duct from the OA port of the air duct where the first heat exchanger 201 is located, and flows to the outside of the first object to be temperature-regulated from the EA port after passing through the first heat exchanger 201, thereby realizing desiccant regeneration; and fresh air enters the air duct from the OA port of the air duct where the second heat exchanger 202 is located, and after passing through the second heat exchanger 202, flows into the first object to be temperature-regulated from the SA port, so as to refrigerate the first object to be temperature-regulated.

The third mode of operation: and in the first mixed working condition mode, the first object to be temperature-regulated is heated, and the second object to be temperature-regulated is refrigerated.

Fig. 10 shows the circulation path of the temperature adjusting medium in this mode, and the conduction states and the communication modes of the respective devices in the temperature adjusting system. As shown in fig. 10, in this operating mode, the first throttling device 208 is opened, the third switching device 215 is turned on, the first switching device 205 is turned on, the second throttling device 210 is opened, the fourth port d4 and the sixth port f6 of the second commutation device 211 are communicated, and the seventh port g7 of the third commutation device 207 is communicated with the tenth port j10, and the eighth port h8 is communicated with the ninth port i 9.

In this operation mode, after being compressed by the compression device 206, the temperature adjusting medium flows from the other gas pipe port of the compression device 206 to the compression device 206 through the ninth port i9 of the third reversing device 207, the eighth port h8 of the third reversing device 207, the first heat exchanger 201, the first throttling device 208, the second heat exchanger 202, the third switching device 215, the first switching device 205, the second throttling device 210, the third heat exchanger 203, the fourth port d4 and the sixth port f6 of the second reversing device 211, the tenth port j10 of the third reversing device 207, and the seventh port g7 of the third reversing device 207, in this order, so as to complete the temperature adjusting medium circulation.

During this cycle, the temperature-regulating medium from the compression device 206 first flows into the first heat exchanger 201, in which case the first heat exchanger 201 acts as a condenser, through which first heat exchanger 201 the temperature-regulating medium releases heat for heating the first temperature-to-be-regulated object. Then, the temperature regulation medium flows to the first throttle device 208, and the pressure of the temperature regulation medium flowing into the second heat exchanger 202 is lower than the pressure of the temperature regulation medium flowing into the first heat exchanger 201 by the throttling action of the first throttle device 208, so that the second heat exchanger 202 functions as an evaporator, and the temperature regulation medium absorbs heat while flowing through the second heat exchanger 202 to dehumidify the return air. After that, the temperature regulation medium flows to the second throttling means 210 through the third switching device 215 and the first switching device 205, and the pressure of the temperature regulation medium flowing into the third heat exchanger 203 is lower than the pressure of the temperature regulation medium flowing into the second heat exchanger 202 under the throttling action of the second throttling means 210, so that the third heat exchanger 203 functions as an evaporator, and the temperature regulation medium absorbs heat while flowing through the third heat exchanger 203 to refrigerate the second object to be temperature regulated.

Fig. 11 shows the states of the first inner damper and the second inner damper in the first mixed operating mode, and as shown in fig. 11, the first inner damper 217 is connected to the outer wall of the first heat exchanger 201 and the bellows wall located on the side of the second heat exchanger 202 away from the first heat exchanger 201, so that the air from the air outlet side of the second heat exchanger 202 enters the air chamber through the first heat exchanger 201, and the second inner damper 219 closes the second air outlet. At this time, the circulating dampers on the two air ducts are both in the second connection state Q, so that the return air enters the air duct from the RA port of the air duct where the second heat exchanger 202 is located, and after passing through the second heat exchanger 202 and the first heat exchanger 201, flows into the first object to be temperature-regulated from the SA port.

A fourth mode of operation: and in the mixed working condition mode II, the first object to be subjected to temperature regulation is heated, and the second object to be subjected to temperature regulation is refrigerated.

Fig. 12 shows the circulation path of the temperature adjusting medium in this mode, and the conduction states and the communication modes of the respective devices in the temperature adjusting system. As shown in fig. 12, in this operating mode, the second switching device 209 is conducting, the third throttling device 214 is open, the fourth switching device 212 is conducting, the first port a1 of the first commutation device 204 is communicating with the second port b2, the second throttling device 210 is open, the fourth port d4 of the second commutation device 211 is communicating with the sixth port f6, and the seventh port g7 of the third commutation device 207 is communicating with the tenth port j10, and the eighth port h8 is communicating with the ninth port i 9.

In this mode of operation, the temperature regulation medium flows through the compression device 206, the ninth port i9 of the third reversing device 207, the eighth port h8 of the third reversing device 207, the first heat exchanger 201 in that order. A portion of the temperature regulating medium flowing from the first heat exchanger 201 flows through the second switching device 209, the second heat exchanger 202, the third switching element 214, the fourth switching device 212, the fourth heat exchanger 213, and to the tenth port j10 of the third reversing device 207 in that order. And another part of the temperature adjusting medium flowing out of the first heat exchanger 201 flows through the first port a1 of the first reversing device 204, the second port b2 of the first reversing device 204, the second throttling device 210, the third heat exchanger 203, the fourth port d4 of the second reversing device 211 and the sixth port f6 of the second reversing device 211 in sequence, and flows to the tenth port j10 of the third reversing device 207. The temperature adjusting medium flowing through the tenth port j10 flows back to the compression device 206 through the seventh port g7, completing the temperature adjusting medium cycle.

During this cycle, the temperature-regulating medium from the compression device 206 first flows into the first heat exchanger 201, in which case the first heat exchanger 201 functions as a condenser, and the temperature-regulating medium flows through the first heat exchanger 201 to release heat for heating the first temperature-to-be-regulated object. Also, since the pressure of the temperature-adjusting medium is substantially equal before and after flowing through the second switching device 209, so that the second heat exchanger 202 also functions as a condenser, the temperature-adjusting medium releases heat while flowing through the second heat exchanger 202 to perform a dehumidification process on the desiccant in the second heat exchanger 202.

As shown in fig. 6, the first inner damper 217 separates the air duct in which the second heat exchanger 202 is located from the air chamber, and the air duct, the second air outlet and the second heat exchanger are all located on the same side of the first inner damper, and the second inner damper exposes the second air outlet. At this time, the circulating air doors on the two air ducts are both in the first connection state P, so that fresh air flows into the air duct from the OA port of the air duct where the first heat exchanger 201 is located, and after entering the air cavity through the first heat exchanger 201, flows into the first object to be temperature-regulated (or the chamber to be temperature-regulated) from the SA port, and heats the first object to be temperature-regulated. After entering the air duct from the OA port of the air duct where the second heat exchanger 202 is located, the fresh air can flow to the outside of the first object to be temperature-regulated from the EA port after passing through the second heat exchanger 202, thereby realizing the regeneration of the desiccant.

The fifth working mode: and in the first heating mode, the first object to be temperature-regulated is heated, and the second object to be temperature-regulated is heated.

Fig. 13 shows the circulation path of the temperature adjusting medium in this mode, and the conduction states and the communication modes of the respective devices in the temperature adjusting system. As shown in fig. 13, in this operating mode, the first throttling device 208 is open, the third throttling device 214 is open, the fourth switching device 212 is conductive, the first port a1 of the first commutation device 204 is in communication with the third port c3, the fourth port d4 of the second commutation device 211 is in communication with the fifth port e5, the second throttling device 210 is open, the first switching device 205 is conductive, and the seventh port g7 of the third commutation device 207 is in communication with the tenth port j10, and the eighth port h8 is in communication with the ninth port i 9.

In this mode of operation, the temperature regulation medium flows through the compression device 206, the ninth port i9 of the third reversing device 207, the eighth port h8 of the third reversing device 207 and the first heat exchanger 201 in that order. A portion of the temperature regulating medium flowing out of the first heat exchanger 201 flows through the first throttling device 208, the second heat exchanger 202, the third throttling device 214 and the fourth switching device 212 in this order. And another part of the temperature regulating medium flowing out of the first heat exchanger 201 flows through the first port a1 of the first reversing device 204, the third port c3 of the first reversing device 204, the fifth port e5 of the second reversing device 211, the fourth port d4 of the second reversing device 211, the third heat exchanger 203, the second throttling device 210, the first switching device 205 and the fourth switching device 212 in this order. And the temperature regulating medium flowing from the eighth port h8 of the third reversing device 207 flows through the fifth port e5 of the second reversing device 211, the fourth port d4 of the second reversing device 211, the third heat exchanger 203, the second throttling device 210, the first switching device 205 and the fourth switching device 212 in this order. The temperature regulation medium flowing out of the fourth switching device 212 flows through the fourth heat exchanger 213, the tenth port j10 of the third reversing device 207, the seventh port g7 of the third reversing device 207, and back to the compression device 206 in this order, completing the temperature regulation medium cycle.

During this cycle, the temperature-regulating medium from the compression device 206 first flows into the first heat exchanger 201, in which case the first heat exchanger 201 acts as a condenser, through which first heat exchanger 201 the temperature-regulating medium releases heat for heating the first temperature-to-be-regulated object. Then, the temperature regulation medium flows to the first throttle device 208, and the pressure of the temperature regulation medium flowing into the second heat exchanger 202 is lower than the pressure of the temperature regulation medium flowing into the first heat exchanger 201 by the throttling action of the first throttle device 208, so that the second heat exchanger 202 functions as an evaporator, and the temperature regulation medium absorbs heat while flowing through the second heat exchanger 202 to dehumidify the return air. And the temperature regulating medium from the compression means 206 also flows into the third heat exchanger 203, so that this third heat exchanger 203 acts as a condenser, through which third heat exchanger 203 the temperature regulating medium flows to release heat for heating the second object to be temperature regulated.

Fig. 11 shows the state of the first inner damper and the second inner damper in the first simultaneous heating mode, and as shown in fig. 11, the first inner damper is connected to the outer wall of the first heat exchanger 201 and the bellows wall located on the side of the second heat exchanger 202 away from the first heat exchanger 201, so that the air from the air outlet side of the second heat exchanger 202 enters the air chamber through the first heat exchanger 201, and the second inner damper closes the second air outlet. At this time, the circulating air doors on the two air ducts are both in the second connection state Q, so that the return air enters the air duct from the RA port of the air duct where the second heat exchanger 202 is located, and after passing through the second heat exchanger 202 and the first heat exchanger 201, flows to the inside of the first object to be temperature-regulated from the SA port.

Sixth mode of operation: and in the second heating mode, the first object to be temperature-regulated is heated, and the second object to be temperature-regulated is heated.

Fig. 14 shows the circulation path of the temperature adjusting medium in this mode, and the conduction states and the communication modes of the respective devices in the temperature adjusting system. As shown in fig. 14, the second switching device 209 is conducting, the third switching device 214 is open, the fourth switching device 212 is conducting, the first port a1 of the first commutation device 204 is in communication with the third port c3, the fourth port d4 of the second commutation device 211 is in communication with the fifth port e5, the second throttling device 210 is open, the first switching device 205 is conducting, and the seventh port g7 of the third commutation device 207 is in communication with the tenth port j10, and the eighth port h8 is in communication with the ninth port i 9.

In the second simultaneous heating mode, the flow pattern of the temperature adjusting medium is different from that in the first simultaneous heating mode only in one place, that is, the temperature adjusting medium flowing out of the first heat exchanger 201 flows to the second heat exchanger 202 through the second switching device 209. At this time, both the first heat exchanger 201 and the second heat exchanger 202 function as condensers. The temperature control medium flows through the first heat exchanger 201 to release heat, so that the first object to be temperature controlled is heated. The temperature adjusting medium flows through the second heat exchanger 202 to release heat, and the moisture absorbent in the second heat exchanger 202 is dehumidified.

As shown in fig. 6, the first inner damper 217 separates the air duct in which the second heat exchanger 202 is located from the air chamber, and the air duct, the second air outlet and the second heat exchanger are all located on the same side of the first inner damper, and the second inner damper exposes the second air outlet. At this time, the circulating air doors of the two air ducts are both in the first connection state P, so that fresh air flows into the air duct from the OA port of the air duct where the first heat exchanger 201 is located, and after entering the air cavity through the first heat exchanger 201, flows into the first object to be temperature-regulated (or the chamber to be temperature-regulated) from the SA port, so as to heat the first object to be temperature-regulated. And after entering the air duct from the OA port of the air duct where the second heat exchanger 202 is located, the fresh air flows to the outside of the first object to be temperature-regulated from the EA port after passing through the second heat exchanger 202, so that the desiccant regeneration is realized.

It should be noted that the temperature of an object to be temperature-regulated can be independently regulated by the temperature regulating system by controlling the devices in the temperature regulating system. Fig. 15 to 22 show schematic diagrams of several circulation paths when the temperature is adjusted individually. The following description is made for each temperature adjustment mode:

the first object to be temperature-regulated is in an independent refrigeration mode: as shown in fig. 15, the first switching device 205 may be closed on the basis of the first simultaneous cooling mode, so that the temperature adjusting medium does not flow through the first switching device, the second throttling device, the third heat exchanger and the second reversing device. Alternatively, as shown in fig. 16, the first reversing device 204 may be closed on the basis of the simultaneous cooling mode two, so that the temperature regulating medium does not flow through the first reversing device, the second throttling device, the third heat exchanger and the second reversing device.

The second object to be temperature-regulated is in an independent refrigeration mode: as shown in fig. 17, the third switching device 215 and the third throttling device 214 may be closed on the basis of the simultaneous cooling mode one so that the temperature-adjusting medium does not flow through the third switching device, the second heat exchanger, the first throttling device, and the first heat exchanger. Alternatively, as shown in fig. 18, the first throttling device 208 and the second switching device 209 may be closed on the basis of the simultaneous cooling mode two so that the temperature adjusting medium does not flow through the first throttling device, the second heat exchanger, the third switching device, the fourth switching device, and the fourth heat exchanger.
