[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0020] Example 1: like Figure 1 As shown, this utility model provides an air conditioning system based on solar-assisted heating, comprising: Solar heater 1, used to heat air using solar energy; The solar heater 1 is provided with a conveying channel 2 for conveying air; And main functional system 3, used for air handling and conveying; Accordingly, the conveying channel 2 is connected to the main functional system 3 to form an auxiliary heating branch connected in parallel to the main functional system 3.

[0021] The system delivers the processed air from the main functional system 3 to the target location, thereby controlling the temperature at that location. It is easy to understand that the solar-assisted heating-based air conditioning system uses air as the medium, and since air sources are widely available, there is no need to worry about environmental pollution.

[0022] The conveying channel 2 connects to the main functional system 3, allowing air from the main functional system 3 to be conveyed to the solar heater 1 via the exhaust fan 6 and the heat recovery pipe 4. The solar heater 1 uses solar energy to heat the air, without using electricity or gas, thus causing no environmental pollution. The heated air is then conveyed back to the main functional system 3 via the heat supply pipe 5 and the exhaust fan 7, and subsequently transported to the target location. This reduces the energy consumption of the main functional system 3.

[0023] Furthermore, the conveying channel 2 is connected in parallel with the main functional system 3, allowing users to choose whether to use the conveying channel 2 and the solar heater 1, making it flexible and better suited to user needs.

[0024] In the aforementioned air conditioning system based on solar-assisted heating, a solar heater 1 is used as an auxiliary heating device to replace the existing auxiliary heating method. While achieving heating, the solar heater 1 has the characteristics of energy saving, environmental protection, better safety, and better installation flexibility. It effectively solves the problems of high energy consumption and high carbon emissions of the existing auxiliary heating method and realizes the efficient utilization of green energy.

[0025] It is worth noting that, depending on the usage, the solar heater 1 provides auxiliary heating with different functions. For example, in summer or during high-temperature periods, the solar heater 1 heats the main functional system 3 to effectively increase the supply air temperature and reduce the reheat energy consumption of the main functional system 3. In winter or during low-temperature periods, the solar heater 1 heats the air to provide indoor heating, thereby reducing the energy consumption of the main functional system 3.

[0026] In one possible implementation, the conveying channel 2 includes a heat recovery pipe 4 and a heat delivery pipe 5, with the heat recovery pipe 4, the solar heater 1, and the heat delivery pipe 5 connected in sequence. The connection point between the heat recovery pipe 4 and the main functional system 3 is located upstream of the connection point between the heat delivery pipe 5 and the main functional system 3.

[0027] Based on the above design scheme, from the perspective of the main functional system 3, along the airflow direction, the heat return pipe 4 is located upstream of the heat delivery pipe 5 to ensure that the air heated by the solar heater 1 does not flow back into the delivery channel 2. It is easy to understand that the heat return pipe 4 and the heat delivery pipe 5 can be made of the same type of pipe to save economic costs.

[0028] In one possible implementation, the heat return pipe 4 is made of galvanized steel pipe or UPVC (unplasticized polyvinyl chloride), and the heat delivery pipe 5 is made of galvanized steel pipe or UPVC. Both the heat return pipe 4 and the heat delivery pipe 5 are wrapped with an insulation layer.

[0029] Based on the above design scheme, galvanized steel pipe has the advantages of excellent corrosion resistance, flexible customization, high pressure resistance, good economy and convenient maintenance, while UPVC has the advantages of strong corrosion resistance, low fluid resistance, high mechanical strength, hygiene and non-toxicity, light weight, convenient installation and good temperature adaptability. Both are suitable for the use environment of the solar-assisted heating air conditioning system, and staff can choose according to the actual situation.

[0030] In addition, by wrapping the heat insulation layer, the heat exchange between the conveying channel 2 and the outside world is further reduced, the heat loss of air when flowing through the conveying channel 2 is reduced, and the heating effect of the solar heater 1 is guaranteed.

[0031] In one possible implementation, an exhaust fan 6 is installed on the heat return pipe 4, and an exhaust fan 7 is installed on the heat supply pipe 5. Based on the above design, the exhaust fan 6 and the exhaust fan 7 provide power for airflow, and these two can be selected according to actual usage.

[0032] In one possible implementation, the solar heater 1 is a solar air heater. It is readily understood that the solar heater 1 can also be any other suitable solar heating device, and this invention does not impose any limitations on this.

[0033] In one possible implementation, the main functional system 3 includes an air handling unit 8, a first regulating valve 9, and a fan 10; The air handling unit 8 has at least two air inlets and at least one air outlet. The air handling unit 8 is provided with two openings located between the air inlets and the air outlet. The two openings are used to connect the heat recovery pipe 4 and the heat supply pipe 5 of the delivery channel 2, respectively. The first regulating valve 9 is provided in two parts and is respectively set on two openings; The fan 10 is located at the end of the air handling unit 8 and is used to transport air.

[0034] Based on the above design scheme, the air handling unit 8 is equipped with multiple air inlets to facilitate air inflow and mixing, which helps to accelerate the air renewal speed at the target location and improve air quality. The number and location of air outlets are set according to the number of target locations for which temperature control is required. It is easy to understand that one air outlet is generally set, but multiple air outlets can be set on the basis of ensuring the control effect.

[0035] The first regulating valve 9 is located at the connection between the air handling unit 8 and the delivery channel 2. By controlling the opening and closing of the first regulating valve 9 and its opening degree, the air volume is controlled, thereby realizing the control and regulation of the air supply temperature in the air handling unit 8.

[0036] The fan 10 is one of the core components of the main functional system 3. The fan 10 regulates the air speed in the air handling unit 8 and delivers the air to the target location. The fan 10 can regulate the temperature of the target location by controlling parameters such as air volume and air speed.

[0037] In one possible implementation, along the air flow direction, the air handling unit 8 includes an air inlet section 11, a filter section 12, an air handling section 13, an exhaust section 15, a second regulating valve 17, a make-up air section 16, and a fan section 14 connected in sequence. Accordingly, the air inlet is located on the air inlet section 11, the filter section 12 is provided with a filter screen, two openings are respectively provided on the exhaust section 15 and the make-up air section 16, and the fan 10 is provided on the fan section 14.

[0038] Based on the above design scheme, the air handling unit 8 is connected to each component to improve the integration of the solar-assisted heating air conditioning system, making the structure of the solar-assisted heating air conditioning system more compact, easier to install, and lower in maintenance cost, which helps to improve the stability and reliability of operation, so as to be used in different application scenarios.

[0039] Preferably, the various functional sections of the air handling unit 8 adopt a modular design to facilitate compact combined installation or decentralized discrete installation to adapt to different operating environments.

[0040] The filter screen is used to filter the air to improve air quality and protect the solar heater 1 and the fan 10.

[0041] When air flows through the exhaust section 15, if the first regulating valve 9 is opened, the air can flow into the heat recovery pipe 4 and through the solar heater 1, thereby heating the air through the solar heater 1. The heated air is then transported to the make-up air section through the heat supply pipe 5, and then flows into the fan section 14.

[0042] The air handling unit 8 is divided into zones by the second regulating valve 17. The second regulating valve 17 can both regulate and separate the zones, preventing the backflow of air heated by the solar heater 1.

[0043] Alternatively, the fan 10 may be a centrifugal fan, an axial flow fan, a mixed flow fan, or a crossflow fan. It is easy to understand that any suitable commercially available model can be selected for the fan 10.

[0044] Optionally, the air inlet section 11 has two staggered air inlets, and the fan section 14 has one air outlet facing the fan 10. Furthermore, the number of air inlets and outlets can be increased appropriately according to actual conditions, making it more flexible and convenient to use.

[0045] In one possible implementation, the solar-assisted heating-based air conditioning system further includes a control module for controlling its operation. This allows for automated and intelligent operation through the control module, reducing human intervention. It is easy to understand that any suitable existing model can be selected for the control module, offering a wide range of choices.

[0046] Example 2: This embodiment is based on embodiment 1, combined with Figure 1 The operating mode of the air conditioning system based on solar-assisted heating is described below: 1. Operation mode that fully utilizes solar-assisted heating The first regulating valve 9 is open, and the second regulating valve 17 is closed or has a small opening, forming a direct solar heating operation mode. After the air enters the air handling unit 8, some of the air in the exhaust section 15 is heated by the first regulating valve 9, the heat return pipe 4, and the solar heater 1, and then returns to the air handling unit 8 through the heat supply pipe 5 and the make-up air section 16, and is sent into the room through the fan section 14.

[0047] 2. Operation mode that partially utilizes solar-assisted heating When the opening of the first regulating valve 9 is reduced, the second regulating valve 17 is opened to a greater degree than the first regulating valve 9. A small portion of the air flowing into the air handling unit 8 flows into the auxiliary heating branch, while most of it flows along the air handling unit 8. Thus, solar energy is used to heat a portion of the air.

[0048] 3. No solar power operation mode The first regulating valve 9 is closed, and the second regulating valve 17 is fully open. The air flowing into the air handling unit 8 will not flow into the auxiliary heating branch, and the solar heater 1 will not participate in heating.

[0049] It is easy to understand that in the above operating mode, if the operating effect of the solar heater 1 cannot meet the usage requirements, any other suitable reheat function module can be added. This function module, together with the air conditioning air supply system based on solar-assisted heating, forms the air conditioning air supply system, thereby ensuring that the air supply temperature meets the standard.

[0050] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
