The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an air conditioning system according to a first embodiment of the present invention. As shown in fig. 1, the air conditioning system of the present invention mainly includes a compressor 11, an evaporator 12, a cross flow fan 13, an electronic expansion valve 14 and a condenser 15, wherein the evaporator 12 performs air cooling heat dissipation through the cross flow fan 13, and the condenser 15 is a counter-flow heat exchanger and dissipates heat through the water flowing through a first working water path or a second working water path. The air conditioner also comprises a water tank 2 as a liquid storage container, a valve assembly and a controller, wherein the controller enables the air conditioning system to be in a state that only the first working water path or the second working water path is communicated by switching the on-off state of the valve assembly, and specifically: the condenser is communicated with the water tank 2 to form a first working water path so as to store heat emitted by a refrigerant in the condenser to the water tank 2 and circularly heat water in the water tank; or the condenser is communicated with the water supply end and the external water outlet to form a second working water channel, so that the heat emitted by the refrigerant in the condenser can be absorbed by the water circulating in the second working water channel in time. As an example, the condenser 15 may be a double pipe heat exchanger or a shell-and-tube heat exchanger, and the double pipe heat exchanger is exemplified by a double pipe heat exchanger including an outer pipe and a plurality of inner pipes assembled in the outer pipe, a high temperature refrigerant flows through the inner pipes, and water flows in the outer pipes in opposite directions. The outer pipe of the double-pipe heat exchanger is provided with a water outlet a, a water outlet b, a water inlet c and a water inlet d, wherein the water tank 2 is communicated with the water outlet a and the water inlet c to form a first working waterway; the water supply end is communicated with the water inlet c, and the external water outlet is communicated with the water outlet d to form a second working waterway. The valve assembly comprises a solenoid valve e and a solenoid valve f, wherein the solenoid valve e is arranged on the first working water path, and the solenoid valve f is arranged on the second working water path. When the air conditioning system is started, the controller opens the first working waterway by enabling the electromagnetic valve e to be in an opening state and enabling the electromagnetic valve f to be in a closing state, so that water in the water tank 2 can be heated circularly; after the set time, the controller controls the solenoid valve e to be closed and controls the solenoid valve f to be opened so as to close the first working waterway and open the second working waterway, so that the cold water at the water supply end can flow through the condenser through the second working waterway to take away the heat of the condenser, and finally, the cold water is directly discharged into the external water outlet.

The advantage of above-mentioned setting lies in: the utility model discloses an air conditioning system is under the condition in water tank 2 and the 15 intercommunication formation first work water routes of condenser, and hydroenergy in the water tank 2 can be by the circulation heating, and the water that is heated can regard as domestic water to use or be utilized through other ways. In the case where the condenser 15 is communicated with the water supply end and the external drain port to form a second working water path, the cold water at the water supply end flows through the condenser 15 through the second working water path to take away the heat of the condenser 15, and is directly discharged into the external drain port. It can be seen that, can also guarantee the radiating effect of condenser when realizing air conditioning system's condenser recycle through the setting in two water routes, and the utility model discloses an air conditioning system passes through the on off state of controller control valve subassembly in order to realize the switching in first work water route and second work water route for two water routes can not produce and interfere, and the water of having avoided the second work water route gets into water tank 2 and causes the influence to the temperature in the water tank 2, has guaranteed the stability of temperature in the water tank 2. In addition, because the flow direction of water and refrigerant in the double-pipe heat exchanger is opposite, be favorable to heat transfer to make the heat transfer effect promote greatly, also can improve the heating efficiency of the water in the water tank 2 simultaneously. And, as for the shell-and-tube heat exchanger, it also has the installation flexibility, and the heat transfer area can change according to actual need, and heat transmission distance is long, advantage that heat recovery efficiency is high.

With continued reference to fig. 1, in a possible embodiment, as shown in fig. 1, the condenser 15 is provided with a first water inlet and a first water outlet, the water tank 2 is provided with a second water inlet and a second water outlet, the first water inlet and the second water outlet are connected by a first pipe group, the first pipe group comprises a first pipe section 31 and a second pipe section 32 arranged along the water flow direction, the first water outlet and the second water inlet are connected by a second pipe group, the second pipe group comprises a third pipe section 33 and a fourth pipe section 34 arranged along the water flow direction, and the second pipe section 32 is provided with a water pump. The first water inlet and the water supply end are connected through a third pipe group, the third pipe group comprises a fifth pipe section 35 and a second pipe section 32 which are arranged along the water flow direction, the first water outlet and the external water outlet are connected through a fourth pipe group, and the fourth pipe group comprises a third pipe section 33 and a sixth pipe section 36 which are arranged along the water flow direction. The valve assembly comprises a first valve 41, a second valve 42, a third valve 43 and a fourth valve 44, wherein the first valve 41 is disposed in the first pipe section 31, the second valve 42 is disposed in the fourth pipe section 34, the third valve 43 is disposed in the fifth pipe section 35, and the fourth valve 44 is disposed in the sixth pipe section 36. The control process of the first working waterway and the second working waterway is as follows: the controller forms a first working water path by communicating the condenser 15 with the tank 2 by opening the first and second valves 41 and 42 and closing the third and fourth valves 43 and 44; the condenser 15 is connected to the water supply port and the external drain port so that the first valve 41 and the second valve 42 are closed and the third valve 43 and the fourth valve 44 are opened, thereby forming only a second working water path in the air conditioning system.

preferably, the water tank 2 is further provided with a user outlet, the user outlet is connected with a hot water outlet pipe section 37, and the hot water outlet pipe section 37 is provided with a first stop valve 45, so that a hot water demand end (such as a hot water faucet) can obtain hot water in the water tank 2 by opening the first stop valve 45. Further, the fifth pipe section 35 is connected to a cold water outlet pipe section 38, a second stop valve 46 is disposed on the cold water outlet pipe section 38, and a cold water demand end (such as a cold water faucet) can obtain water in the water supply end by opening the second stop valve 46. In this way, the user can obtain hot water from the hot water demand side by opening the first cut-off valve 45, or obtain cold water from the cold water demand side by opening the second cut-off valve 46, thereby facilitating the daily water demand of the user.

Preferably, the first valve 41, the second valve 42 and the fourth valve 44 are solenoid valves, and the third valve 43 is a check valve. The controller only needs to control the on-off states of the first valve 41, the second valve 42 and the fourth valve 44, and the third valve 43 can be automatically opened and closed without the control of the controller. Specifically, when the first valve 41 and the second valve 42 are closed, the water pressure at the left end of the check valve is lower than the water pressure at the right end, and the check valve is opened without being controlled by the controller. In addition, the third valve 43 is provided with a check valve to realize automatic water replenishment of the water tank 2. Specifically, under the condition that the first working waterway is opened, if the user uses hot water through the hot water outlet pipe 37 at this time, the water pressure in the first working waterway will be lowered, and since the water pressure of the first working waterway is smaller than the pressure of the water supply end, the check valve will be opened at this time so that cold water can be supplemented into the first working waterway. And because the pressure at the front end of the water pump 51 is low, the supplemented cold water does not enter the water tank 2 from the bottom of the water tank 2, but enters the water pump 51, then enters the condenser 15, is heated and then enters the water tank 2. It can be seen that the setting of check valve both can realize the automatic replenishment of cold water, can prevent again that the hot water backward flow in first working water route from getting into the water supply end, avoids water supply end to pollute.

Of course, it can be understood by those skilled in the art that the valve types of the first valve 41, the second valve 42, the third valve 43, and the fourth valve 44 are not limited to the above examples, and those skilled in the art can flexibly set the valve types according to the practical application scenarios, for example, the first valve 41, the second valve 42, the third valve 43, and the fourth valve 44 can also be set as electric valves.

With continued reference to fig. 1, in one possible embodiment, as shown in fig. 1, a temperature detecting member 21 (e.g., a temperature sensor) for acquiring the temperature of the water in the water tank 2 is provided in the water tank 2 at a position near the second water outlet. The temperature detecting means 21 detects the temperature of the water in the life water tank 2 and sends it to the controller. The temperature sensing member 21 is provided to accurately monitor the temperature state of the water in the water tank 2 so that the controller controls the open and close state of the valve assembly according to the temperature of the water in the water tank 2. As a possible example, when the air conditioning system is turned on, the temperature detecting member 21 detects the temperature of the water in the water tank 2, and if the temperature of the water in the water tank 2 is detected to be lower than the set temperature, the controller turns on the water pump 51, the first valve 41 and the second valve 42, and turns off the third valve 43 and the fourth valve 44, so that the water in the water tank 2 enters the condenser 15 from the first pipe section 31 and the second pipe section 32 in sequence to absorb the heat of condensation, and then enters the water tank 2 through the third pipe section 33 and the fourth pipe section 34. It can be seen that, in the first working waterway communication process, the water in the water tank 2 is circularly heated, and the temperature of the water in the water tank 2 is gradually increased. When the temperature detecting member 21 detects that the temperature of the water in the water tank 2 reaches the set temperature, the controller opens the third valve 43 and the fourth valve 44 and closes the first valve 41 and the second valve 42, the first working water path is closed, the second working water path is opened, the cold water at the water supply end enters the condenser 15 from the fifth pipe section 35 and the second pipe section 32 in sequence to absorb the condenser 15, and the water coming out of the condenser 15 does not enter the water tank 2 but is discharged to the external drain port through the third pipe section 33 and the sixth pipe section 36. Thus, the water in the second working waterway can be prevented from entering the water tank 2 to influence the water temperature in the water tank 2, and the stability of the water temperature in the water tank 2 is ensured.

it will be appreciated that although in the above example the controller controls the on/off state of the valve assembly according to the temperature of the water in the water reservoir 2, this is only a preferred embodiment, and not a limitation, the controller may also control the on/off state of the valve assembly according to time or other parameters, which can be flexibly set by a person skilled in the art according to actual needs.

Preferably, the second water outlet is provided at the bottom of the water tank 2, and the second water inlet is provided at the top of the water tank 2. Through this kind of setting for hot water gathers at 2 tops of water tank all the time, and cold water gathers at 2 bottoms of water tank all the time, has formed the overall arrangement of "hot water is last, cold water is under" from this, thereby utilizes the density difference that the temperature difference produced to reduce cold water to the disturbance of hot water, avoids forming the convection heat transfer, has effectively solved and has scurried the temperature problem. And during the circulation heating of the water in the water tank 2, the water at the lower temperature at the bottom of the water tank 2 is sucked into the water pump 51 and can be heated again in the condenser 15.

Considering that the water entering the water tank 2 contains small bubbles, the small bubbles are accumulated and gathered at the top of the water tank 2, not only the space of the water tank 2 is occupied, but also the bubbles entering the water pump 51 can cause cavitation erosion to the overflowing part of the water pump 51 and can generate noise and vibration, thereby causing the performance reduction of the pump, and even leading the water pump 51 to be incapable of working normally in severe cases. In view of this, further, the top of the water tank 2 is further provided with an automatic exhaust valve 22, and the air bubbles in the water tank 2 are exhausted through the automatic exhaust valve 22 at the top of the water tank 2, so that the air bubbles can be prevented from occupying the space of the water tank 2, the cavitation of the water pump 51 can be effectively prevented and reduced, and the quality and the performance of the water pump 51 can be guaranteed.

Referring next to fig. 2, fig. 2 is a schematic structural diagram of an air conditioning system according to a second embodiment of the present invention. In one possible embodiment, the controller controls the water pump to make the water flow speed in the second working waterway smaller than that in the first working waterway. The arrangement of the water pumps may be various, as shown in fig. 2, as one possible example, the first pipe section 31 is provided with a first water pump 52, and the fifth pipe section 35 is provided with a second water pump 53, wherein the water flow velocity in the second water pump 53 is smaller than that in the first water pump 52. Through the arrangement, the water in the second working water channel can be fully exchanged with the condenser 15 and then discharged to the external water outlet, so that the water is saved. Of course, the arrangement of the water pump is not limited to the above example, for example, a water pump with two-gear power may be further arranged at the second pipe section 32, and the controller controls the water flow rates of the first working water path and the second working water path by switching the power of the water pump. In addition, in the case where two water pumps are provided, the positions of the water pumps are not limited to the above example, and the first water pump 52 may be provided in the fourth pipe section 34 and the second water pump 53 may be provided in the sixth pipe section 36. The technical personnel in the field can flexibly adjust the number and the arrangement position of the water pumps according to the actual situation so as to meet the specific application requirements.

It will be appreciated by those skilled in the art that the valve assembly can be arranged in any manner not limited to the above examples, and that those skilled in the art can flexibly adjust the number, type and arrangement position of the valves in the valve assembly according to the actual situation. As a possible example, as shown in fig. 3, a three-way valve a47 may be provided at the intersection of the first pipe segment 31, the second pipe segment 32, and the fifth pipe segment 35, and a three-way valve b48 may also be provided at the intersection of the third pipe segment 33, the fourth pipe segment 34, and the sixth pipe segment 36, and the controller may control the three-way valves a47 and b48 to switch the first working waterway and the second working waterway.

To sum up, the utility model discloses an air conditioning system sets up condenser 15 into through the mode heat dissipation of water circulation in first work water route or second work water route and through the switching of control to the on off state of valve member in order to realize the switching in two water routes to under the normal radiating prerequisite of assurance condenser, hydroenergy in the water tank 2 can be through first work water route by cyclic heating, has realized the recycle of condensation heat. Preferably, a temperature detection member 21 is disposed in the water tank 2 at a position close to the second water outlet at the bottom of the water tank 2, and the temperature detection member 21 can accurately monitor the temperature state of the water in the water tank 2, so that the controller can control the switching of the two water paths according to the temperature of the water in the water tank 2. Further, the controller is through controlling the water pump to make the rivers speed in the second work water route be less than the rivers speed in the first work water route, thereby make the water in second work water route can carry out abundant heat exchange with condenser 15, thereby avoid the rivers in second work water route too fast, and the heat transfer is insufficient between water and the interior refrigerant of condenser and leads to the problem of water waste.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
