[0044] In addition, if the terms "first", "second" and the like appear, they are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] It is found through research that multi-connected water heater units, with the characteristics of air conditioning + floor heating + domestic hot water multifunction, have attracted widespread attention and strong demand. Multi-connected water heater units have both refrigeration and hot water requirements, such as refrigeration in summer and hot water for kitchen and bathing.

[0047] The existing multi-connected water heater units have the following situations:

[0048] ①Conventional multi-split: during refrigeration operation, the heat released by the high-temperature and high-pressure refrigerant through the heat exchanger of the condenser is not effectively utilized.

[0049] ②Multi-split heat recovery system: a mode conversion device is used to realize the condensation heat, which is expensive and complex to install.

[0050] ②Sky fluorine and water system: refrigeration and hot water can be realized. However, when the refrigeration / heat demand and the hot water demand exist at the same time, the refrigerant distribution is uneven, resulting in the inability to balance the air conditioning and hot water effects. The solution is generally to control according to priority, such as first running the hot water, and then starting the indoor unit when the hot water temperature is stable, which causes inconvenience in use.

[0051] Therefore, there is an urgent need for a system that can balance the air conditioning demand and the hot water demand.

[0052] In view of the above problems, the present embodiment provides a water supply device for an air conditioner and an air conditioner. The water supply device for an air conditioner comprises: a water power module, a controllable high-pressure gas pipe, and a controllable high-pressure liquid pipe. One end of the controllable high-pressure gas pipe is connected to the oil separation of the air conditioner, the other end of the controllable high-pressure gas pipe is connected to the water power module, the controllable high-pressure gas pipe is connected to the four-way valve of the air conditioner, one end of the controllable high-pressure liquid pipe is connected to the external heat exchanger of the air conditioner, and the other end of the controllable high-pressure liquid pipe is connected to the water power module. By providing a water supply device for an air conditioner, a system that can effectively balance the air conditioning demand and the hot water demand is obtained. The following will describe the scheme provided by the present embodiment in detail.

[0053] Please refer to Figure 1 , Figure 1 for a structure diagram of a water supply device for an air conditioner. The following will describe the device including various components in detail.

[0054] The water supply device for an air conditioner comprises: a water power module 1, a controllable high-pressure gas pipe 2, and a controllable high-pressure liquid pipe 3. The air conditioner 4 comprises an oil separation 41, a four-way valve 42, and an external heat exchanger 43. One end of the controllable high-pressure gas pipe 2 is connected to the oil separation 41 of the air conditioner, the other end of the controllable high-pressure gas pipe 2 is connected to the water power module 1, the controllable high-pressure gas pipe 2 is connected to the four-way valve 42 of the air conditioner, one end of the controllable high-pressure liquid pipe 3 is connected to the external heat exchanger 43 of the air conditioner, and the other end of the controllable high-pressure liquid pipe 3 is connected to the water power module 1.

[0055] The controllable high-pressure gas pipe 2 is used to transmit the high-temperature and high-pressure gas compressed by the air conditioner compressor to the water power module. The water power module heats the water based on the high-temperature and high-pressure gas, thereby realizing the function of hot water production.

[0056] The cooled refrigerant is transmitted to the external heat exchanger 43, and then enters the indoor unit or the outdoor unit of the air conditioner for normal operation.

[0057] The connection relationship of the controllable high-pressure gas pipe, the controllable high-pressure liquid pipe and the water power module with the air conditioner can realize the original refrigeration or heating of the air conditioner without causing waste of heat, and the heat is input into the water power module through the controllable high-pressure gas pipe to realize the function of heating water. And the cooled refrigerant is still recovered into the air conditioner for the conventional function of the air conditioner.

[0058] As shown in Figure 2 The water supply device of the air conditioner includes a second EXV valve EXV2, the first EXV valve EXV1 is connected with the external heat exchanger 43 and the heat dissipation module 44 respectively, specifically, the first end of the first EXV valve EXV1 is connected with the external heat exchanger 43, the other end of the first EXV valve EXV1 is connected with a liquid storage tank, and the liquid storage tank is connected with the heat dissipation module.

[0059] The third EXV valve EVX2 is connected with the indoor unit 45 and the liquid pipe 46 respectively, and the second EXV valve EXV3 is connected with the water power module 1 and the controllable high-pressure liquid pipe 3 respectively.

[0060] The liquid pipe 46 is an important pipeline connecting the external heat exchanger 43 and the heat dissipation module, responsible for transporting high-pressure liquid refrigerant. The liquid pipe 46 plays a key role in the air conditioner refrigeration cycle, ensuring that the refrigerant flows from the external heat exchanger 43 to the expansion valve, preparing for the subsequent evaporation process.

[0061] The first EXV valve EXV1 is used to control the opening degree of the refrigerant to the heat dissipation module 44, the second EXV valve EXV2 is used to control the opening degree of the refrigerant to the water power module 1, and the second EXV valve EXV3 is used to control the opening degree of the refrigerant to the indoor unit 45. The running state of the air conditioner and the water supply device of the air conditioner can be controlled by controlling the opening state of the four-way valve 42, the first EXV valve EXV1, the second EXV valve EXV2 and the third EXV valve EXV3.

[0062] The running state of the air conditioner and the water supply device of the air conditioner includes the air conditioner refrigeration state, the air conditioner heating state, the air conditioner heating state and the water supply device heating water state, and the air conditioner refrigeration state and the water supply device heating water state.

[0063] When the running state is the air conditioner refrigeration state, the four-way valve 42 is powered off, the first EXV valve EXV1 is opened, the second EXV valve EXV2 is closed, and the third EXV valve EXV3 is opened. In the air conditioner refrigeration state, the second EXV valve EXV2 is closed, which means that the refrigerant discharged by the compressor cannot flow through the water power module 1, which is the same as the conventional refrigeration operation mode of the air conditioner, please refer to Figure 2The refrigerant flow path is compressor→four-way valve 42→outdoor heat exchanger 43→EXV1→indoor unit 45→four-way valve 42→gas-liquid separator→compressor, and the cycle is repeated in this way.

[0064] When the running state is the air conditioning refrigeration state and the water supply device supplies hot water, the four-way valve is powered off, the first EXV valve is opened, the second EXV valve is opened, and the third EXV valve is opened.

[0065] It should be noted that in this running state, the opening state of the first EXV valve EXV1 can be set to a throttling state, i.e., opened according to the first set opening degree. The second EXV valve EXV2 and the third EXV valve EXV3 can be set to a fully open state, i.e., the opening degrees of the second EXV valve EXV2 and the third EXV valve EXV3 are the maximum opening degrees of the expansion valves.

[0066] The first set opening degree can be set to [120p-280p], which is not specifically limited in the embodiments of the present application.

[0067] In the air conditioning refrigeration state and the water supply device supplies hot water state, the first EXV valve EXV1 is throttled, the second EXV valve EXV2 and the third EXV valve EXV3 are fully opened, and the refrigerant discharged by the compressor is divided into two paths, one part of the refrigerant flow path is compressor→four-way valve 42→outdoor heat exchanger 43, and the other part of the refrigerant flow path is compressor→controllable high-pressure gas pipe 2→water power module 1→controllable high-pressure liquid pipe 3. The two parts of the refrigerant are combined before the heat dissipation module 44 and then flow into the evaporator of the indoor unit 45 to realize the refrigeration function of the air conditioner.

[0068] When the running state is the air conditioning refrigeration state and the water supply device supplies hot water, whether the refrigerant distribution is reasonable is determined by the opening degree value of the third EXV valve EXV3 and the supercooling valve opening degree value of the air conditioner, so as to adjust the opening degree of the first EXV valve EXV1. Whether the indoor side heat exchange capacity and the refrigerant distribution are reasonable is determined by judging the supercooling degree at the supercooling plate of the air conditioner, and the opening degree of the second EXV valve EXV2 is adjusted.

[0069] As shown in FIG. 1, a flowchart of an air conditioning control method is shown, which includes the following steps: Figure 3

[0070] S101: Determine the opening degree value of the third EXV valve and the supercooling valve opening degree value of the air conditioner.

[0071] S102: When the opening degree value of the third EXV valve EXV3 is less than the first preset opening degree, or the supercooling valve opening degree value of the air conditioner exceeds the second preset opening degree, the opening degree of the first EXV valve is adjusted.

[0072] ​S103: When the opening value of the third EXV valve is less than the third preset opening value, or the opening value of the subcooling valve of the air conditioner is less than the fourth preset opening value, the opening value of the first EXV valve is adjusted.

[0073] Specifically, if the opening value of the third EXV valve EXV3 is less than the first preset opening value, or the opening value of the air conditioner's subcooling valve exceeds the second preset opening value, it is determined that too much refrigerant is flowing to the indoor side, and the heat exchange capacity of the hydraulic module 1 is insufficient. Then, the opening value of the first EXV valve EXV1 is adjusted. The first EXV valve EXV1 can be controlled to be adjusted according to the first adjustment value to reduce the opening value of the first EXV valve EXV1 until the opening value of the third EXV valve EXV3 is less than or equal to the first preset opening value and greater than or equal to the third preset opening value, or the opening value of the air conditioner's subcooling valve is less than or equal to the second preset opening value or greater than or equal to the fourth preset opening value. Among these, the first preset opening value is greater than the third preset opening value, and the second preset opening value is greater than the fourth preset opening value. The first preset opening value and the third preset opening value constitute the first range of the opening value of the third EXV valve EXV3, and the second preset opening value and the third preset opening value constitute the second range of the opening value of the subcooling valve, thereby improving the heat exchange capacity of the hydraulic module 1.

[0074] If the opening value of the third EXV valve EXV3 is less than the third preset opening value, or the opening value of the subcooling valve of the air conditioner is less than the fourth preset opening value, it indicates that there is too much refrigerant on the hydraulic module 1 side and insufficient heat exchange capacity on the indoor side. The first EXV valve EXV1 is then adjusted according to the second adjustment value to increase the opening value of the first EXV valve EXV1 until the opening value of the third EXV valve EXV3 meets the first range, or the opening value of the subcooling valve meets the second range.

[0075] It should be noted that the first range can be set to [180p, 240p], the second range can be set to [250p, 320p], the first adjustment value can be set to -5p / s, and the second adjustment value can be set to 5p / s.

[0076] The second EXV valve EXV2 can be opened according to the second set opening degree, and the subcooling degree at the subcooling plate of the air conditioner is determined. Based on the subcooling degree, the heat exchange capacity on the indoor side and whether the refrigerant distribution is reasonable are judged, and the second EXV valve EXV2 is adjusted.

[0077] like Figure 4 The diagram shown is a schematic of an air conditioning control method, which includes the following steps:

[0078] S201: Determine the subcooling level at the subcooling plate of the air conditioner.

[0079] S202: When the subcooling is greater than the first preset subcooling, control the second EXV valve to increase according to the third adjustment value.

[0080] S203: When the supercooling degree is less than the second preset supercooling degree, the second EXV valve is controlled to decrease according to a fourth adjustment value.

[0081] The second set opening degree can be set between [150p, 300p], and the embodiments of the present application do not make specific limitations.

[0082] Specifically, when the supercooling degree is greater than the first preset supercooling degree, it indicates that the indoor side heat exchange capacity is large enough, and the water power module 1 side is small, so that the refrigerant flows to the water power module 1 side as much as possible, and the second EXV valve EXV2 is controlled to increase according to a third adjustment value. When the supercooling degree is less than the second preset supercooling degree, it indicates that the indoor side heat exchange capacity is insufficient, and the refrigerant flows to the indoor side as much as possible, and the second EXV valve EXV2 is controlled to decrease according to a fourth adjustment value, so as to ensure the indoor side heat exchange effect.

[0083] It should be noted that the first preset supercooling degree is greater than the second preset supercooling degree, the first preset supercooling degree can be set according to actual conditions, and can be set to 5, the second preset supercooling degree can be set according to actual conditions, and can be set to 0. The third adjustment value can be set to 10p / 30s, and the fourth adjustment value can be set to -10p / 30s. The embodiments of the present application do not make specific limitations on the third adjustment value and the fourth adjustment value.

[0084] In the air conditioning heating state, the four-way valve 42 is powered on, the first EXV valve EXV1 is opened, the second EXV valve EXV2 is closed, and the third EXV valve EXV3 is opened. In the air conditioning heating state, the second EXV valve EXV2 is closed, which indicates that the refrigerant discharged by the compressor cannot flow through the water power module 1. The refrigerant flow path is the same as that in the conventional heating operation mode, that is, compressor→four-way valve 42→indoor unit 45→third EXV valve EXV3→outer heat exchanger 43→four-way valve 42→gas-liquid separator→compressor, and so on.

[0085] In the air conditioning heating state and the hot water supply device hot water supply state, the four-way valve 42 is powered on, the first EXV valve EXV1 is opened, the second EXV valve EXV2 is opened, and the third EXV valve EXV3 is opened.

[0086] In the air conditioning heating state and the hot water supply device hot water supply state, at this time, the second EXV valve EXV2 is opened and in the throttling mode, the first EXV valve EXV1 and the third EXV valve EXV3 are fully opened. After the refrigerant is discharged by the compressor, it is divided into two parts. One part of the refrigerant flow path is compressor→four-way valve 42→indoor unit 45→second EXV valve EXV2, and the other part is compressor→controllable high-pressure gas pipe 2→water power module 1→controllable high-pressure liquid pipe 3. The two parts of the refrigerant are combined before the heat dissipation module 44 and flow into the outer heat exchanger 43.

[0087] When the running state is the air conditioning heating state and the water supply device is in the hot water supply state, the indoor heat exchange capacity and the refrigerant distribution are determined to be reasonable by determining the heating capacity of the indoor unit, and the opening of the second EXV valve EXV2 is adjusted to make the refrigerant distribution reasonable.

[0088] Specifically, it is judged whether the heating capacity of the ratio of the indoor heating capacity to the rated indoor heating capacity belongs to the third range. If the ratio of the indoor heating capacity to the rated indoor heating capacity exceeds the third range, i.e. greater than the upper limit value of the third range, it means that the required heat exchange capacity of the indoor side is large, and the refrigerant should flow to the indoor side as much as possible. The opening of the second EXV valve EXV2 on the water module side is reduced according to the first adjustment value, and if the ratio of the indoor heating capacity to the rated indoor heating capacity is less than the lower limit value of the third range, it means that the heat exchange capacity of the indoor side is sufficient, and the heat exchange capacity of the water module is insufficient, and the refrigerant should flow to the water module side as much as possible. The opening of the second EXV valve EXV2 is controlled to increase according to the second adjustment value to ensure the hot water effect.

[0089] It should be noted that the third range can be set according to the actual situation, which can be set to [90%, 110%], and the embodiment of the present application does not make specific limitation.

[0090] Still referring to Figure 2 The water supply device of the air conditioner further comprises a water supply module 5, and the water supply module 5 is connected with the water module 1, and the water module 1 is used for heating the water in the water supply module 5.

[0091] The water supply module comprises at least one of the following: floor heating, water tank, humidifier and anti-freezing device.
