The air conditioning unit comprises a refrigerant circulation loop 110, and the refrigerant circulation loop 110 is provided with a water heating heat exchanger 107; the water heating unit comprises a hot water circulation loop 120, and a plurality of heat dissipation modules 200 are connected on the hot water circulation loop 120 in parallel; wherein, the water heating heat exchanger 107 exchanges heat with the hot water circulation loop 120 so as to form hot water in the hot water circulation loop 120; the water inlet end of each heat dissipating module 200 is provided with a solenoid valve 222, and the solenoid valve 222 is used for adjusting the flow of hot water entering the corresponding heat dissipating module 200.

In this embodiment, as shown in fig. 1, a compressor 100, a first four-way valve 101, an outdoor heat exchanger 103, a first electronic expansion valve 105, an indoor unit 104 and a second four-way valve 102 are sequentially arranged on a refrigerant circulation loop 110, and the refrigerant circulation loop 110 can perform indoor refrigeration and heating; the refrigerant circulation loop 110 includes a first pipe section 111, one end of the first pipe section 111 is disposed between the outdoor heat exchanger 103 and the indoor unit 104 on the refrigerant circulation loop 110, the other end is connected with the second four-way valve 102, and the first pipe section 111 is provided with the water heating heat exchanger 107 and the second electronic expansion valve 106.

When the air conditioning system is refrigerating, dc communication and es communication of the first four-way valve 101 are performed; the de communication and cs communication of the second four-way valve 102, the first electronic expansion valve 105 is closed, and the second electronic expansion valve 106 is opened. The high-temperature and high-pressure refrigerant discharged from the compressor 100 enters the first pipe section 111 through the second four-way valve 102, the first pipe section 111 exchanges heat with the hot water circulation loop 120 at the hot water heat exchanger 107, the temperature of the refrigerant is reduced, and the temperature of the water in the hot water circulation loop 120 is increased after absorbing the heat of the refrigerant. The hot water in the hot water circulation circuit 120 flows into the plurality of heat radiating modules 200, and the heat radiating modules 200 are used for heating the indoor. The cooled liquid refrigerant enters the indoor unit 104 to evaporate and absorb heat after passing through the second electronic expansion valve 106, so as to provide cold for the indoor space, and then the refrigerant returns to the compressor 100 through the second four-way valve 102, thus completing one refrigerant cycle.

In the present embodiment, a plurality of heat dissipating modules 200 are disposed in parallel on the hot water circulation circuit 120, and a water inlet end of each heat dissipating module 200 is provided with a solenoid valve 222. In this way, when the heat dissipation loads of the plurality of heat dissipation modules 200 are different, the opening of the electromagnetic valve 222 is adjusted to adjust the flow of hot water entering the corresponding heat dissipation module 200, so as to individually adjust the temperature of each heat dissipation module 200.

Optionally, a water separator 210 and a water collector 211 are provided on the hot water circulation circuit 120. The water knockout drum 210 is provided with a plurality of water knockout openings connected in parallel, and the water inlet end of each heat dissipation module 200 is communicated with one water knockout opening; the water collector 211 is provided with a plurality of water collecting ports connected in parallel, and the water outlet end of each heat dissipation module 200 is communicated with one water collecting port.

In this embodiment, as shown in fig. 2, the hot water circulation loop 120 includes a second pipe section 121, and the second pipe section 121 is used to exchange heat with the hot water heat exchanger 107 to form hot water. The water collector 211 is disposed upstream of the second pipe section 121, and the water separator 210 is disposed downstream of the second pipe section 121. First, the hot water in the second pipe section 121 flows to the water separator 210 and flows into the corresponding heat dissipation module 200 through the water separation ports. When the heat radiation module 200 heats up the room, the water temperature is reduced and flows into the water collector 211 through the corresponding water collecting port. Finally, the water in the water collector 211 flows back to the second pipe section 121 and is reheated, thereby forming a hot water circulation, and continuously supplying hot water to the plurality of heat radiating modules 200.

Here, the system piping shown in fig. 2 is communicated with the system piping shown in fig. 3, that is, 1-1, 2-2, 3-3, 4-4 corresponding to fig. 2 and 3 are respectively communicated.

Optionally, the air conditioning system further comprises a temperature sensing assembly and a controller. The temperature sensing assembly is used for detecting the water inlet temperature and the water outlet temperature of the heat dissipation module 200; the controller is electrically connected to the temperature sensing assembly and the solenoid valve 222, and is configured to adjust the opening of its corresponding solenoid valve 222 according to the actual temperature difference between the inlet water temperature and the outlet water temperature of the heat dissipation module 200.

In this embodiment, the temperature sensing assembly includes a water inlet temperature sensor and a water outlet temperature sensor. The water inlet temperature sensor is used for detecting the water inlet temperature of the heat dissipation module 200 and transmitting a temperature signal to the controller; the outlet water temperature sensor is used for detecting the outlet water temperature of the heat dissipation module 200 and transmitting a temperature signal to the controller. The controller calculates the actual temperature difference obtained by subtracting the outlet water temperature from the inlet water temperature, and adjusts the opening of the electromagnetic valve 222 according to the actual temperature difference, so that the temperature difference of the plurality of heat dissipation modules 200 is reduced as much as possible, and the temperature rising/reducing rate is kept consistent.

Optionally, in the case that the actual temperature difference of the heat dissipating module 200 is greater than the first threshold, the controller controls the opening of the solenoid valve 222 to decrease each time by a first percentage of the maximum opening until decreasing to a second percentage of the maximum opening; wherein the first percentage and the second percentage are the same or different.

In this embodiment, the first threshold is set by the user, for example, the first threshold is set to set the temperature difference +1deg.C. Since the actual temperature difference is large, the opening of the controller-controlled solenoid valve 222 is reduced at this time. Thus, the flow rate of the hot water flowing into the corresponding heat radiation module 200 is reduced, and thus the temperature of the water inlet end of the heat radiation module 200 is reduced and the actual temperature difference is reduced. And the opening degree is reduced in a gradient manner, so that the temperature change of the heat dissipation module 200 is more stable.

Illustratively, the first percentage and the second percentage are both 10%. The controller controls the opening of the solenoid valve 222 to decrease by 10% each time until it decreases to 10% of the maximum opening.

Optionally, in the case that the actual temperature difference of the heat dissipation module 200 is less than the second threshold, the controller controls the opening of the solenoid valve 222 to increase by a third percentage of the maximum opening each time, until the maximum opening; wherein the second threshold is less than the first threshold.

In this embodiment, the second threshold is set by the user, for example, the second threshold is set to set the temperature difference of-1 ℃. Since the actual temperature difference is small, the opening of the solenoid valve 222 is controlled to be increased by the controller. Thus, the flow rate of the hot water flowing into the corresponding heat radiation module 200 increases, so that the temperature of the water inlet end of the heat radiation module 200 increases and the actual temperature difference increases. And the opening degree is increased in a gradient manner, so that the temperature change of the heat radiation module 200 is more stable.

Illustratively, the third percentage is 10%. The controller controls the opening of the solenoid valve 222 to increase by 10% each time until the maximum opening.

Alternatively, in the case where the actual temperature difference of the heat dissipation module 200 is greater than or equal to the second threshold value and less than or equal to the first threshold value, the controller controls the solenoid valve 222 to maintain the current opening. In this way, the current temperature of the heat dissipation module 200 can be maintained.

Optionally, setting the sum of the temperature difference and the first compensation value as a first threshold value, and setting the difference of the temperature difference and the second compensation value as a second threshold value; wherein the first compensation value is the same as or different from the second compensation value. The temperature difference is set to be 1-14 ℃. The preferred range of the set temperature difference is 2-12 ℃, and the preferred value of the set temperature difference is 5 ℃.

The temperature difference is set to 5 ℃ and the first compensation value and the second compensation value are 1 ℃ in an exemplary manner. The temperature difference +1deg.C is set as a first threshold value, namely 6deg.C, and the temperature difference-1deg.C is set as a second threshold value, namely 4deg.C. The plurality of heat dissipation modules 200 includes three ground heating modules 201, which are respectively referred to as a first ground heating module, a second ground heating module, and a third ground heating module, and corresponding solenoid valves 222 are respectively referred to as a first solenoid valve, a second solenoid valve, and a third solenoid valve. The actual temperature difference of the first floor heating module is 5 ℃, and the controller controls the first electromagnetic valve to maintain the current opening. The actual temperature difference of the second floor heating module is 3 ℃, and the controller controls the opening of the second electromagnetic valve to be increased at the moment, so that the actual temperature difference is improved. The actual temperature difference of the third floor heating module is 7 ℃, and the controller controls the opening of the third electromagnetic valve to be reduced at the moment, so that the actual temperature difference is reduced.

In some embodiments, the air conditioning system further comprises a temperature sensing assembly and a controller. The temperature sensing assembly is used for detecting the actual temperature of the heat dissipation module 200; the controller is electrically connected to the temperature sensing assembly and the solenoid valve 222, and is configured to control the on-off state of the corresponding solenoid valve 222 according to the actual temperature of the heat dissipation module 200.

In this embodiment, the temperature sensing assembly includes an actual temperature sensor for detecting an actual temperature of the heat dissipation module 200 and transmitting a temperature signal to the controller. After the controller receives the temperature signal, the controller controls the opening and closing of the solenoid valve 222 according to the actual temperature.

Alternatively, in the case that the actual temperature of the heat dissipation module 200 is less than the set temperature, the controller controls the corresponding solenoid valve 222 to be opened. At this time, the actual temperature cannot meet the user demand, the solenoid valve 222 is opened to allow the hot water of the hot water circulation loop 120 to enter the heat dissipation module 200, thereby increasing the actual temperature.

Optionally, in the case that the actual temperature of the heat dissipation module 200 is greater than the set temperature, the controller controls the corresponding solenoid valve 222 to be closed. At this time, the actual temperature is high, and the solenoid valve 222 is closed to achieve the energy saving effect. In this way, the on-off state of each solenoid valve 222 can be effectively controlled, and erroneous judgment of the on-off state is avoided.

The air conditioning unit comprises a refrigerant circulation loop 110, and the refrigerant circulation loop 110 is provided with a water heating heat exchanger 107; the water heating unit comprises a hot water circulation loop 120, and a plurality of heat dissipation modules 200 connected in parallel are arranged on the hot water circulation loop 120; wherein, the water heating heat exchanger 107 exchanges heat with the hot water circulation loop 120 so as to form hot water in the hot water circulation loop 120; the water inlet end of each heat radiation module 200 is provided with a water mixing valve 221, and the water inlet of the water mixing valve 221 is communicated with the hot water circulation loop 120 and the low-temperature water source 220; the opening degree of the water mixing valve 221 is different, and the flow rates of the cold water and the hot water entering the corresponding heat radiation module 200 are different.

In the present embodiment, a plurality of heat dissipating modules 200 are disposed in parallel on the hot water circulation circuit 120, and a water mixing valve 221 is disposed at the water inlet end of each heat dissipating module 200.

The floor heating module 201 is laid under the floor of the room, and the heating module 202 is disposed in the room. In the case where the user's required temperatures for the floor heating module 201 and the heating module 202 are different, the temperatures of the floor heating module 201 and the heating module 202 may be individually adjusted by adjusting the opening of the water mixing valve 221.

In this embodiment, the temperature sensing assembly includes an actual temperature sensor for detecting an actual temperature of the heat dissipation module 200 and transmitting a temperature signal to the controller. After receiving the temperature signal, the controller adjusts the opening of the water mixing valve 221 according to the actual temperature, and further adjusts the temperature of the heat dissipation module 200 individually. Preferably, the actual temperature sensor detects the actual temperature every 10 minutes, and the controller adjusts according to the actual temperature.

Alternatively, in case that the actual temperature of the heat radiation module 200 is greater than the set temperature, the controller controls the opening of the water mixing valve 221 to make the cold water flow greater than the hot water flow.

In the present embodiment, only hot water flows when the opening of the water mixing valve 221 is maximum, and only cold water flows when the opening is minimum; the controller controls the opening of the water mixing valve 221 to decrease the fourth percentage of the maximum opening each time until the opening is minimum, so that the cold water flow is greater than the hot water flow, and the temperature of the heat dissipation module 200 is lowered to be close to the set temperature. And the opening degree is reduced in a gradient manner, so that the temperature change of the heat dissipation module 200 is more stable.

Illustratively, the fourth percentage is 10%. The set temperature of a certain floor heating module 201 is 45 deg.c, and the actual temperature thereof is 65 deg.c. At this time, the controller controls the opening of the water mixing valve 221 to be reduced by 10% each time until the opening is minimized, thus increasing the flow rate of cold water entering the floor heating module 201, and thus smoothly reducing the temperature of the floor heating module 201.

Alternatively, in case that the actual temperature of the heat dissipation module 200 is less than the set temperature, the controller controls the opening of the water mixing valve 221 to make the hot water flow greater than the cold water flow.

And the opening degree is increased in a gradient manner, so that the temperature change of the heat radiation module 200 is more stable.

Illustratively, the fifth percentage is 10%. The set temperature of a certain heating module 202 is 65 ℃, and the actual temperature thereof is 45 ℃. At this time, the controller controls the opening of the water mixing valve 221 to be increased by 10% each time until the opening is maximized, thus increasing the flow rate of hot water entering the heating module 202, and thus smoothly increasing the temperature of the heating module 202.

Alternatively, in the case where the set temperatures of the plurality of heat dissipation modules 200 are different, the air conditioning unit operates with the highest set temperature as the target temperature.

Illustratively, the plurality of heat dissipating modules 200 includes two floor heating modules 201 and one heating module 202. The set temperatures of the two heating modules 202 are 35 ℃ and 45 ℃ respectively, and the set temperature of the heating module 202 is 65 ℃.
