Description

Technical Field

[0001] The present application relates to the field of air-conditioning technology, for example, to an air-conditioning system. Background Art

[0002] Currently, buildings use air conditioning systems to meet the human body's demand for thermal comfort in their living environments. Since indoor air circulation follows the basic convection mechanism of hot air rising and cold air sinking, when the user's indoor space needs to be heated up, the hot air blown out by the air conditioner indoor unit hanging on the user's indoor ceiling cannot sink to the area near the floor. This reduces the heat exchange efficiency of the air conditioning system and the user's sense of thermal comfort in the living environment. For example, the indoor temperature in the human head area is often higher, while the temperature in the human foot area is still very low, and the overall body still feels cold.

[0003] In order to make up for the defect that the hot air generated by the air-conditioning system cannot sink, floor heating using hot water as the medium is also laid in existing buildings.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] However, using both hot water as the medium for floor heating and refrigerant as the medium for air conditioning increases the heat exchange losses of the two systems.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0048] The present disclosure provides an air conditioning system. Figures 1 to 8 shown.

[0049] Optionally, the air conditioning system includes a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, a throttling element 4, and an indoor module, wherein the indoor module includes an indoor heat exchanger group and a radiant floor heating group. The air conditioning system further includes a first three-way valve 7, a first connecting pipe 81, a second connecting pipe 82, and a third connecting pipe 83. The first three-way valve 7 includes a first connecting end, a second connecting end, and a third connecting end. The first connecting pipe 81 is connected to the four-way valve 2 and the first connecting end of the first three-way valve 7. The second connecting pipe 82 is connected to the indoor heat exchanger group and the second connecting end of the first three-way valve 7. The third connecting pipe 83 is connected to the radiant floor heating group and the third connecting end of the first three-way valve 7.

[0050] In the air-conditioning system provided by the embodiment of the present disclosure, the first connecting pipe 81 connected to the four-way valve 2 is provided with a first three-way valve 7, and the first three-way valve 7 is connected to the indoor heat exchanger group and the radiant floor heating group through the second connecting pipe 82 and the third connecting pipe 83, respectively. In this way, when the air-conditioning system operates in the heating mode, the refrigerant can be distributed to the indoor heat exchanger group and the radiant floor heating group respectively through the first three-way valve 7. The radiant floor heating group makes up for the defect that the heat generated by the indoor heat exchanger group cannot sink, thereby improving the temperature comfort of the user's indoor space. In addition, the indoor heat exchanger group and the radiant floor heating group simultaneously use refrigerant as the heat exchange medium to heat the same indoor space of the user, thereby reducing the heat exchange loss of the air-conditioning system when operating in the heating mode.

[0051] The indoor heat exchanger group heats the user's indoor space by heat convection, and the radiant floor heating group heats the user's indoor space by heat radiation. It can be seen that the indoor heat exchanger group and the radiant floor heating group have different heating methods. In the embodiment of the present disclosure, the refrigerant flowing out of the compressor 1 is divided into two by the first three-way valve 7, one path enters the indoor heat exchanger group, which can be simply referred to as "sky fluorine", and the other path enters the radiant floor heating group, which can be simply referred to as "ground fluorine". In this way, the amount of refrigerant can be distributed to the indoor heat exchanger group and the radiant floor heating group through the first three-way valve 7, reducing the heat exchange loss of the air-conditioning system when it is running in the heating mode.

[0052] Optionally, the indoor heat exchanger group includes a first indoor heat exchanger 51, a second indoor heat exchanger 52, a third indoor heat exchanger, etc., which are respectively installed in different indoor spaces of the user. Optionally, the first indoor heat exchanger 51, the second indoor heat exchanger 52, or the third indoor heat exchanger can be a wall-mounted air conditioner, a ducted air conditioner, or an embedded air conditioner. Optionally, multiple indoor heat exchangers in the indoor heat exchanger group are connected in parallel.

[0053] Optionally, the radiant floor heating system includes a first fluorine radiant panel 61, a second fluorine radiant panel 62, and a third fluorine radiant panel 63, respectively, which are installed in different indoor spaces of the user. Optionally, the first fluorine radiant panel 61, the second fluorine radiant panel 62, and the third fluorine radiant panel 63 are laid on the floor of the user's indoor space. Optionally, the multiple fluorine radiant panels in the radiant floor heating system are connected in parallel.

[0054] Optionally, the radiant floor heating group includes a first fluorine radiation plate 61 arranged in the first indoor space and a second fluorine radiation plate 62 arranged in the second indoor space, the first fluorine radiation plate 61 includes a first radiation plate inlet, a first radiation plate outlet and a first radiation pipeline arranged between the first radiation plate inlet and the first radiation plate outlet; the second fluorine radiation plate 62 includes a second radiation plate inlet, a second radiation plate outlet and a second radiation pipeline arranged between the second radiation plate inlet and the second radiation plate outlet.

[0055] Among them, the radiant floor heating group also includes a first collecting pipe 601, which is connected to the third connecting pipe 83, and is respectively connected to the first radiation plate inlet of the first fluorine radiation plate 61 and the second radiation plate inlet of the second fluorine radiation plate 62, so as to distribute the refrigerant of the third connecting pipe 83 to the first fluorine radiation plate 61 and the second fluorine radiation plate 62 through the first collecting pipe 601.

[0056] In the air-conditioning system provided by the embodiment of the present disclosure, a first manifold 601 is respectively connected to the third connecting pipe 83, the first radiation plate inlet of the first fluorine radiation plate 61, and the second radiation plate inlet of the second fluorine radiation plate 62. In this way, refrigerant can be distributed to the first fluorine radiation plate 61 and the second fluorine radiation plate 62 respectively through the first manifold 601, thereby improving the accuracy of temperature regulation of the user's indoor space by different fluorine radiation panels.

[0057] Optionally, the radiant floor heating system further includes a first connecting branch pipe and a second connecting branch pipe. The first connecting branch pipe connects between the first manifold 601 and the first radiant plate inlet of the first fluorine radiant plate 61 and is provided with a first valve component 611 to regulate the amount of refrigerant flowing into the first fluorine radiant plate 61. The second connecting branch pipe connects between the first manifold 601 and the second radiant plate inlet of the second fluorine radiant plate 62 and is provided with a second valve component 621 to regulate the amount of refrigerant flowing into the second fluorine radiant plate 62.

[0058] The amount of refrigerant flowing from the first manifold 601 into the first fluorine radiant plate 61 can be adjusted by adjusting the opening of the first valve component 611. For example, when the air conditioning system is operating in heating mode and the user's set temperature differs significantly from the actual temperature of the first indoor space, the opening of the first valve component 611 can be increased to increase the amount of refrigerant flowing into the first fluorine radiant plate 61 and enhance the heating effect of the first fluorine radiant plate 61. Optionally, the first valve component 611 is a solenoid valve.

[0059] Similarly, the amount of refrigerant flowing from the first manifold 601 into the second fluorine radiant plate 62 can be adjusted by adjusting the opening of the second valve component 621. For example, when the air conditioning system is operating in heating mode and the user's set temperature differs significantly from the actual temperature of the second indoor space, the opening of the second valve component 621 can be increased to increase the amount of refrigerant flowing into the second fluorine radiant plate 62, thereby improving the heating effect of the second fluorine radiant plate 62. Optionally, the second valve component 621 is a solenoid valve.

[0060] It can be seen that the provision of the first valve component 611 and the second valve component 621 improves the accuracy of the first fluorine radiation plate 61 and the second fluorine radiation plate 62 in regulating the heating temperature of the first indoor space and the second indoor space respectively.

[0061] Optionally, the inner diameter of the first header 601 is greater than or equal to the inner diameter of the first connecting branch pipe; similarly, the inner diameter of the first header 601 is greater than or equal to the inner diameter of the second connecting branch pipe.

[0062] Optionally, the radiant floor heating group further includes a second header 602 , which is connected to the first radiation plate outlet of the first fluorine radiation plate 61 and the second radiation plate outlet of the second fluorine radiation plate 62 .

[0063] The refrigerant flowing out of the first fluorine radiation plate 61 and the second fluorine radiation plate 62 is combined by the second header 602 .

[0064] Optionally, the inner diameter of the second header 602 is the same as the inner diameter of the first header 601 .

[0065] Optionally, the first header 601 and the second header 602 are arranged in a steam separation and liquid collection pipe installation room.

[0066] Optionally, the air conditioning system further includes a fourth connecting line 84 and a fifth connecting line 85. The fourth connecting line 84 connects between the throttling element 4 and the indoor heat exchanger group; the fifth connecting line 85 connects between the fourth connecting line 84 and the second header 602. Furthermore, the fifth connecting line 85 is provided with a first conducting component 851 that conducts from the second header 602 to the fourth connecting line 84.

[0067] The fifth connecting pipe 85 is provided with a first conducting component 851. The first conducting component 851 is a unidirectional conducting component that conducts electricity from the second manifold 602 to the fourth connecting pipe 84. This ensures that the radiant floor heating system in the air conditioning system is only conducting when operating in heating mode, so that the radiant floor heating system only provides heating effect.

[0068] Optionally, the first conducting component 851 includes a one-way valve or a solenoid valve.

[0069] The first conducting component 851 with a one-way conducting function can be a one-way valve, or the first conducting component 851 can also be a solenoid valve, and controls the solenoid valve to conduct from the second manifold 602 to the fourth connecting pipe 84, and controls the solenoid valve to close from the fourth connecting pipe 84 to the second manifold 602.

[0070] Optionally, the first radiation pipeline includes a microchannel pipeline; and / or the second radiation pipeline includes a microchannel pipeline.

[0071] The microchannel radiation pipeline includes a clamping plate 642 and an upper shell 641. The clamping plate 642 is evenly distributed with multiple side-by-side metal strips 643. The upper shell 641 covers the metal strips 643 to form a sealed cavity. The upper shell 641 and the metal strips 643, the clamping plate 642 and the metal strips 643, and the metal strips 643 are tightly attached to form a continuous microchannel 100. It can be understood that the metal strips 643 are tightly attached to the clamping plate 642, and there is no gap between the metal strips 643 and the metal strips 643, and between the metal strips 643 and the clamping plate 642, so as to prevent the refrigerant from jumping through the gap or short-circuiting. Figure 8 shown.

[0072] Optionally, the indoor heat exchanger group includes a first indoor heat exchanger 51 arranged in the first indoor space and a second indoor heat exchanger 52 arranged in the second indoor space, wherein the refrigerant inlet end or the refrigerant outlet end of the first indoor heat exchanger 51 is provided with a third valve component 511, and the refrigerant inlet end or the refrigerant outlet end of the second indoor heat exchanger 52 is provided with a fourth valve component 521.

[0073] In this manner, the first indoor space is provided with both the first indoor heat exchanger 51 and the first fluorine radiation panel 61. When the air conditioning system operates in heating mode, the first indoor space can be heated simultaneously by the first indoor heat exchanger 51 and the first fluorine radiation panel 61. Furthermore, a third valve component 511 is provided at the refrigerant inlet or outlet of the first indoor heat exchanger 51. The amount of refrigerant flowing through the first indoor heat exchanger 51 can be adjusted by adjusting the opening of the third valve component 511.

[0074] The second indoor space is equipped with both a second indoor heat exchanger 52 and a second fluorine radiation panel 62. When the air conditioning system is operating in heating mode, the second indoor space can be heated simultaneously by the second indoor heat exchanger 52 and the second fluorine radiation panel 62. Furthermore, a fourth valve component 521 is provided at the refrigerant inlet or outlet of the second indoor heat exchanger 52. The amount of refrigerant flowing through the second indoor heat exchanger 52 can be adjusted by adjusting the opening of the fourth valve component 521.

[0075] Optionally, the laying areas of the first fluorine radiation plate 61 and the second fluorine radiation plate 62 may be set according to the sizes of the first indoor space and the second indoor space, respectively.

[0076] Optionally, the air conditioning system can operate in a cooling mode with the indoor heat exchanger group alone.

[0077] The first three-way valve 7 is controlled to connect the first connecting line 81 with the second connecting line 82, and to close the third connecting line 83. The refrigerant flowing out of the compressor 1 flows through the outdoor heat exchanger 3, the throttling element 4, and the indoor heat exchanger group in sequence, thereby realizing the independent cooling of the indoor heat exchanger group of the air-conditioning system. The refrigerant flow path in this mode is as follows Figure 4 shown.

[0078] Optionally, the air conditioning system can operate in a separate heating mode with the indoor heat exchanger group.

[0079] The first three-way valve 7 is controlled to connect the first connecting line 81 with the second connecting line 82, and to close the third connecting line 83. The refrigerant flowing out of the compressor 1 flows through the indoor heat exchanger group, the throttling element 4, and the outdoor heat exchanger 3 in sequence, thereby realizing the independent heating of the indoor heat exchanger group of the air-conditioning system. The refrigerant flow path in this mode is as follows Figure 5 shown.

[0080] Optionally, the air conditioning system can operate in a separate heating mode for the radiant floor heating group.

[0081] The first three-way valve 7 is controlled to connect the first connecting line 81 with the third connecting line 83, and to close the second connecting line 82. The refrigerant flowing out of the compressor 1 flows through the radiant floor heating group, the throttling element 4, and the outdoor heat exchanger 3 in sequence, thereby realizing the independent heating of the radiant floor heating group of the air conditioning system. The refrigerant flow path in this mode is as follows Figure 6 shown.

[0082] Optionally, the air conditioning system can also operate the indoor heat exchanger group and the radiant floor heating group in a joint heating mode.

[0083] Control the first three-way valve 7 to connect the first connecting pipe 81 and the second connecting pipe 82, and at the same time connect the third connecting pipe 83. The refrigerant flowing out of the compressor 1 is diverted by the first three-way valve 7 and flows into the indoor heat exchanger group and the fluorine radiation floor heating group respectively. At this time, the first conduction component 851 is in the conduction state. After the indoor heat exchanger group and the fluorine radiation floor heating group complete heating, they flow through the throttling element 4 and the outdoor heat exchanger 3 in turn, and finally flow back to the compressor 1. The refrigerant flow path in this mode is as follows Figure 7 shown.

[0084] Optionally, the air conditioning system further includes a first control unit configured to adjust the openings of the first valve component 611 and the second valve component 621 according to a first preset temperature of the first indoor space and a second preset temperature of the second indoor space.

[0085] When the air conditioning system operates in the radiant floor heating unit's standalone heating mode, the openings of the first valve component 611 and the second valve component 621 can be adjusted based on the preset temperatures of different rooms. Alternatively, the openings of the corresponding valve components can be adjusted based on the difference between the set temperature and the current temperature of each room, thereby improving the accuracy of the radiant floor heating unit's indoor temperature regulation.

[0086] Optionally, the air conditioning system further includes a second control unit and a third control unit. The second control unit is configured to adjust the openings of the first valve component 611 and the third valve component 511 according to a first preset temperature of the first indoor space; and the third control unit is configured to adjust the openings of the second valve component 621 and the fourth valve component 521 according to a second preset temperature of the second indoor space.

[0087] Different rooms have different preset temperatures, and the indoor heat exchanger group and the radiant floor heating group heat the air differently. The openings of the first valve component 611 and the third valve component 511 can be adjusted simultaneously based on the first preset temperature of the first indoor space, allowing the first indoor heat exchanger 51 and the first fluorine radiation plate 61 to more accurately regulate the temperature at different heights of the user's first indoor space. Similarly, the openings of the second valve component 621 and the fourth valve component 521 can be adjusted simultaneously based on the second preset temperature of the second indoor space, allowing the second indoor heat exchanger 52 and the second fluorine radiation plate 62 to more accurately regulate the temperature at different heights of the user's second indoor space.
