Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, specifically to a duplex energy-saving water-cooled air conditioner. Background Technology

[0002] An air conditioner, also known as an air conditioner, is a device that uses artificial means to regulate and control parameters such as temperature, humidity, cleanliness, and airflow within a building or structure. Air conditioners are divided into cooling-only air conditioners and cooling-heating air conditioners; their working principle is the same. Previously, most air conditioners used Freon as the refrigerant. Freon's characteristic is that it releases a large amount of heat when changing from a gaseous state to a liquid state, and absorbs a large amount of heat when changing from a liquid state to a gaseous state. Currently, air conditioners have become an indispensable household appliance.

[0003] However, the existing evaporative air conditioning system has insufficient cooling capacity, and its cooling range is limited to the temperature difference between the circulating water temperature and the ambient temperature. The effect is poor when the water temperature is high, and it cannot meet the special needs of high-temperature places. Among them, heat pump air conditioners, whether air-cooled or water-cooled, achieve the purpose of cooling by physically changing the form of the medium, and consume more energy during the cooling process. Therefore, the problem of meeting the special needs of high-temperature environments while achieving energy conservation and consumption reduction is an urgent issue to be solved in this field. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a duplex energy-saving water-cooled air conditioner, which solves the problems of insufficient cooling intensity, limited cooling range to the temperature difference between circulating water temperature and ambient temperature, poor effect at high water temperatures, inability to meet the special needs of high-temperature environments, and high energy consumption during the cooling process.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a duplex energy-saving water-cooled air conditioner, including an air conditioner housing, wherein the air conditioner housing has three cavities inside, and an energy-saving mechanism is installed inside the air conditioner housing; The energy-saving mechanism includes a compressor and a condenser fixedly connected to the inner wall of the cavity below the air conditioner housing. The compressor and the outer ring of the condenser are connected through a first pipe. A water evaporator and a self-circulating evaporator are fixedly connected to the inner walls of the middle and upper cavities of the air conditioner housing, respectively. A second pipe and a third pipe are connected below the water evaporator, and the lower part of the second pipe is connected to the inner ring of the condenser. The lower part of the self-circulating evaporator is connected to the outer ring of the condenser and the compressor through a fourth pipe and a fifth pipe, respectively. The condenser is a barrel-type condenser with two internal spaces. The first pipe is wound around the inner ring of the condenser for circulating refrigerant. The second and sixth pipes are connected to the outer ring of the condenser for circulating water in the water evaporator. The third pipe passes through the air conditioner housing and connects to the external structure to achieve water circulation.

[0006] Preferably, a sixth pipe is connected to the lower side wall of the condenser; the sixth pipe passes through the air conditioner housing and connects to the external structure.

[0007] Preferably, a fan is fixedly connected to the inner wall of the middle cavity of the air conditioner housing, and the air outlet pipe of the fan is connected to the upper cavity of the air conditioner housing. After the fan is started, the outside air enters the middle cavity of the air conditioner housing through the water evaporator side to achieve cooling, and is then blown into the upper cavity. After being cooled a second time by the self-circulating evaporator, it is discharged into the room from the air outlet of the air conditioner housing to achieve cooling of the indoor air.

[0008] Preferably, an expansion valve is installed on the fourth pipe.

[0009] Preferably, the outer side of the water evaporator is connected to the air inlet of the air conditioner housing; a filter structure can be provided at the air inlet of the air conditioner housing.

[0010] Preferably, the outer side of the self-circulating evaporator is connected to the air outlet of the air conditioner housing; a filter structure can be provided at the air outlet of the air conditioner housing. Beneficial effects

[0011] This invention provides a duplex energy-saving water-cooled air conditioner, which has the following beneficial effects: This dual-type energy-saving water-cooled air conditioner cools the water in the second pipe located on the outer ring of the condenser during the initial operation of the compressor. The water then flows into the water evaporator, thus pre-cooling the air before the air conditioner starts cooling. Once the cooling is fully activated, the water evaporator can further enhance the cooling effect, resulting in faster cooling. At the same time, when the air conditioner reaches the set temperature, the compressor stops working, but the fan continues to run, and the water evaporator continues to provide cooling, greatly delaying the time it takes for the compressor to restart due to rising ambient temperature. This reduces the compressor's operating time, thereby achieving greater energy savings. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1 The present invention provides a technical solution: a duplex energy-saving water-cooled air conditioner, including an air conditioner housing 1, the air conditioner housing 1 having three cavities inside, and an energy-saving mechanism installed inside the air conditioner housing 1; The energy-saving mechanism includes a compressor 2 and a condenser 3 fixedly connected to the inner wall of the cavity below the air conditioner housing 1. The compressor 2 and the outer ring of the condenser 3 are connected through a first pipe 4. A water evaporator 5 and a self-circulating evaporator 6 are fixedly connected to the inner walls of the middle and upper cavities of the air conditioner housing 1, respectively. A second pipe 9 and a third pipe 10 are connected below the water evaporator 5. The lower part of the second pipe 9 is connected to the inner ring of the condenser 3. The lower part of the self-circulating evaporator 6 is connected to the outer ring of the condenser 3 and the compressor 2, respectively, through a fourth pipe 7 and a fifth pipe 8. The condenser 3 is a barrel-type condenser with two internal spaces. The first pipe 4 is wound around the inner space of the condenser 3 for circulating Freon. The second pipe 9 and the sixth pipe 11 are connected to the outer space of the condenser 3 for circulating water in the water evaporator 5. The third pipe 10 passes through the air conditioner casing 1 and connects to the external structure to realize water circulation.

[0016] In this embodiment, a sixth pipe 11 is connected to the lower side wall of the condenser 3; The sixth pipe 11 passes through the air conditioner casing 1 and connects to the external structure.

[0017] In this embodiment, the air conditioner housing 1 is further configured such that a fan 12 is fixedly connected to the inner wall of the middle cavity of the air conditioner housing 1, and the air outlet pipe of the fan 12 is connected to the upper cavity of the air conditioner housing 1. After the fan 12 is started, outside air enters the middle cavity of the air conditioner housing 1 through the water evaporator 5, achieving cooling. It is then blown into the upper cavity, and after being cooled a second time by the self-circulating evaporator 6, it is discharged into the room through the air outlet of the air conditioner housing 1, thus achieving cooling of the indoor air.

[0018] In this embodiment, an expansion valve 13 is further configured to be installed on the fourth pipe 7.

[0019] In this embodiment, the outer side of the water evaporator 5 is connected to the air inlet of the air conditioner housing 1; A filter structure can be installed at the air inlet of the air conditioner housing 1.

[0020] In this embodiment, the outer side of the self-circulating evaporator 6 is connected to the air outlet of the air conditioner housing 1; A filter structure can be installed at the air outlet of the air conditioner housing 1.

[0021] In this system, the air is pre-cooled by the water evaporator 5 and then transported by the fan to the evaporator 6 for forced cooling, thereby enhancing the cooling effect. When the cooling system stops working, the water evaporator continues to pre-cool, thus achieving energy saving. In other words, a water evaporator is added to the water-cooled air conditioner. The water pipe of the water evaporator is connected to the condenser of the water-cooled air conditioner. The original evaporator is installed at the air outlet of the air conditioner. The advantage of this layout is that it reduces wind resistance and facilitates the cleaning and maintenance of the evaporator. Through this reasonable layout, it has both evaporative air cooler and water-cooled air conditioner modes.

[0022] It is worth noting that all standard parts used in this invention can be purchased commercially, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The models of electrical structures and equipment involved can be selected according to the user's needs, as long as they meet the requirements of this application. Furthermore, the circuit connections adopt conventional connection methods in the prior art. The supporting electrical structures for control, current detection, position feedback, predicted voltage synchronization, and parameter adjustment of the electrical equipment are all existing technologies, such as PLC controllers and module structures, and therefore will not be described in detail here. All content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example: When this device is needed, assemble the components according to the diagram, ensuring bolts are tightened and welds are secure. Then connect the circuit and control devices, check all interfaces for errors, and power on for testing to ensure current detection, position feedback, and other functions are normal. Install the control devices in appropriate positions, then turn on the air conditioner. The compressor 2 starts working, compressing the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then transported to the condenser 3 through the first pipe 4. Since the condenser 3 uses a barrel-type refrigerant, the first pipe 4 is wound around the inner ring of the condenser 3 for circulating Freon. The second pipe 9 and the sixth pipe 11 are connected to the outer ring of the condenser 3 for circulating water in the water evaporator 5. Thus, when the high-temperature, high-pressure gaseous refrigerant exchanges heat with the outside air and gradually condenses into a high-temperature, high-pressure liquid refrigerant, the liquid refrigerant located on the outer ring of the condenser 3... The water in the second pipe 9 is cooled and then flows into the water evaporator 5, thus cooling the air in advance before the air conditioner starts cooling. At the same time, the high-temperature and high-pressure liquid refrigerant flows through the fourth pipe 7 to the expansion valve 13. The expansion valve 13 throttles and reduces the pressure of the liquid refrigerant, turning it into low-temperature and low-pressure wet vapor. The wet vapor then enters the self-circulating evaporator 6. In the self-circulating evaporator 6, the wet vapor absorbs heat from the air and further evaporates into low-temperature and low-pressure gaseous refrigerant, lowering the air temperature. The low-temperature and low-pressure gaseous refrigerant then flows back to the compressor 2 through the fifth pipe 8, completing a complete refrigeration cycle. At the same time, the fan 12 starts working, and the outside air enters the middle cavity of the air conditioner casing 1 through one side of the water evaporator 5, achieving cooling. It is then blown into the upper cavity, and after being cooled a second time by the self-circulating evaporator 6, it is discharged into the room from the air outlet of the air conditioner casing 1, achieving cooling of the indoor air. Meanwhile, once the cooling system is fully activated, the water evaporator 5 can assist in improving the cooling effect, thus cooling down faster. When the air conditioner reaches the set temperature, the compressor 2 stops working, but the fan 12 continues to run, and the water evaporator 5 continues to play a role in cooling down. This greatly delays the time it takes for the compressor 2 to restart due to the rise in ambient temperature, thereby reducing the working time of the compressor 2 and achieving a more energy-efficient result.
