Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a multi-effect condensing evaporative cooling industrial air conditioner. Background Technology

[0002] In the field of industrial air conditioning technology, the core working principle of traditional air conditioning systems is based on thermodynamic cycles. They primarily rely on the coordinated operation of four core components: the compressor, condenser, electronic expansion valve, and evaporator, to transfer and dissipate indoor heat, thereby regulating indoor temperature. Traditional air conditioning systems use air-cooled condensers that rely on airflow to remove heat. However, in high-temperature or poorly ventilated environments, the heat dissipation effect decreases significantly due to the already high air temperature. This forces the air conditioning system to consume more energy to maintain a stable indoor temperature, thus increasing electricity consumption. Therefore, it is necessary to improve existing technologies to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a multi-effect condensing evaporative cooling industrial air conditioner, which aims to solve the problem of low heat dissipation efficiency in traditional air conditioning systems in the prior art.

[0004] To achieve the above objectives, this utility model provides a multi-effect condensing evaporative cooling industrial air conditioner, including an indoor unit and an outdoor unit. The refrigerant circulates between the indoor and outdoor units through refrigerant pipes. In the direction of circulation, a condenser, a recooler, a recirculating cooler, an electronic expansion valve, an evaporator, and a compressor are arranged sequentially. The condenser and the recooler are both located in the outdoor unit, while the recirculating cooler, the electronic expansion valve, and the evaporator are all located in the indoor unit.

[0005] The outdoor unit is also equipped with a water tank and a condenser cooling fan. The recooler is immersed in the water tank. A wet curtain and a spray head connected to the water tank are installed above the water tank. The water in the water tank is pumped to the spray head by a water pump and sprayed onto the wet curtain. The water in the wet curtain falls back into the water tank. The condenser cooling fan is used to drive the outdoor air to flow through the wet curtain and then through the surface of the condenser. The air absorbs the heat of the condenser and is then discharged to the outside.

[0006] A condensate collection tank is installed below the evaporator to collect the condensate formed by the evaporator. The recooler is located at the condensate collection tank. The indoor unit is also equipped with an indoor fan to drive indoor air to flow over the surface of the evaporator and send the cooled air into the room.

[0007] Furthermore, the upper side of the condensate collection tank is connected to the water tank.

[0008] Furthermore, the recooler is a coil immersed in the bottom of the condensate collection tank.

[0009] Furthermore, a water supply pipe is connected to the upper side of the water tank, and a water filter is installed on the water supply pipe.

[0010] Furthermore, the water supply pipe is connected to a float switch, which is located on the upper inner side of the water tank.

[0011] Furthermore, a drain pipe is connected to the lower side of the water tank.

[0012] Furthermore, the drain pipe is connected to a drain valve switch.

[0013] Furthermore, the recooler is a coil immersed in a water tank.

[0014] Furthermore, the recooler is made of 316 stainless steel coils.

[0015] Furthermore, an air duct is formed inside the outdoor unit, and a wet curtain, condenser, and condenser cooling fan are arranged in sequence inside the air duct. An air filter is installed at the air inlet of the air duct.

[0016] This invention provides a multi-effect condensing evaporative cooling industrial air conditioner. Compared to existing technologies, the compressor delivers high-temperature, high-pressure gaseous refrigerant to the condenser. Under the action of the condensing cooling fan, outdoor air first passes through a wet curtain for cooling and humidification, then dissipates heat to the condenser. The refrigerant undergoes its first heat dissipation at the condenser, and the low-temperature, humid air facilitates sufficient heat dissipation. The recooler is immersed in a water tank, where the water temperature is lower than the refrigerant temperature, further absorbing heat from the refrigerant and forming a second heat dissipation. The recooler is located at the condensate collection tank, which collects condensate from the evaporator. The condensate temperature is even lower than the water temperature in the tank, further absorbing heat from the refrigerant and forming a third heat dissipation. Through this triple-effect condensing cooling mode, the overall system efficiency is improved, the refrigerant pressure and temperature are more effectively controlled, ensuring stable cooling output and avoiding insufficient cooling capacity due to high temperatures. Furthermore, the compressor can operate at lower power for the same cooling capacity requirement, thereby reducing compressor energy consumption. Attached Figure Description

[0022] The present invention will be described in detail below with reference to specific embodiments.

[0023] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0024] This utility model provides a multi-effect condensing evaporative cooling industrial air conditioner, such as... Figures 1 to 2 As shown, it includes an indoor unit 1 and an outdoor unit 2. Refrigerant circulates between the indoor unit 1 and the outdoor unit 2 through refrigerant pipes. In the direction of circulation, a condenser 21, a recooler 22, a recirculating cooler 11, an electronic expansion valve 12, an evaporator 13, and a compressor 14 are arranged sequentially. The condenser 21 and the recooler 22 are both located inside the outdoor unit 2, while the recooler 11, the electronic expansion valve 12, and the evaporator 13 are all located inside the indoor unit 1. The compressor 14 can be located in either the indoor unit 1 or the outdoor unit 2, depending on the situation. The outdoor unit 2 also includes a water tank 23 and a condenser cooling fan 24. The recooler 22 is immersed in the water tank 23. A wet curtain 25 is installed above the water tank 23 and connected to the water tank 23. Water from the water tank 23 is pumped to the spray head 26 by the water pump 27 and then sprayed onto the wet curtain 25. The water in the wet curtain 25 falls back into the water tank 23. The condenser fan 24 drives the outdoor air to flow through the wet curtain 25 and then through the surface of the condenser 21. The air absorbs the heat from the condenser 21 and is then discharged to the outside. A condensate collection tank 15 is provided below the evaporator 13 to collect the condensate formed by the evaporator 13. The recooler 11 is located at the condensate collection tank 15. The indoor unit 1 is also equipped with an indoor fan 16 to drive the indoor air to flow through the surface of the evaporator 13. The air is cooled and then sent into the room.

[0025] Based on the above structural configuration, compressor 14 delivers high-temperature, high-pressure gaseous refrigerant to condenser 21. Under the action of condenser cooling fan 24, outdoor air first passes through wet curtain 25 for cooling and humidification, and then dissipates heat to condenser 21. The refrigerant forms the first heat dissipation at condenser 21, and the low-temperature, humid air is conducive to the condenser 21 dissipating heat fully. Recooler 22 is immersed in water tank 23. The temperature of the water in water tank 23 is lower than the temperature of the refrigerant in recooler 22, further absorbing the heat of the refrigerant in recooler 22, forming the second heat dissipation. Recooler 11 is set in condensate collection tank 1. At point 5, the condensate collection tank 15 collects the condensate generated on the evaporator 13. The temperature of the condensate is lower than that of the water in the water tank 23, further absorbing the heat of the refrigerant in the recooler 11, forming a third heat dissipation. Through the above-mentioned triple-effect condensation heat dissipation mode, the overall efficiency of the system is improved, the pressure and temperature of the refrigerant can be controlled more effectively, ensuring a stable output of cooling capacity, avoiding the problem of insufficient cooling capacity caused by high temperature, and enabling the compressor 14 to operate at a lower power under the same cooling capacity demand, thereby reducing the energy consumption of the compressor 14.

[0026] In this embodiment, the upper side of the condensate collection tank 15 is connected to the water tank 23. When there is too much condensate in the condensate collection tank 15, the condensate will flow into the water tank 23, realizing the recycling of condensate, saving water resources, and making full use of the low-temperature cold source of the condensate to dissipate heat for the recooler 22, which is beneficial to improving the heat dissipation effect of the recooler 22. Of course, the condensate collection tank 15 may not be connected to the water tank 23, and the condensate in the condensate collection tank 15 may be drained directly when there is too much condensate.

[0027] In this embodiment, the recooler 11 is a coil immersed in the bottom of the condensate collection tank 15. After the condensate generated on the evaporator 13 enters the condensate collection tank 15, the low-temperature condensate accumulates at the bottom of the condensate collection tank 15, making it easier to contact the recooler 11, ensuring the cooling effect and significantly improving the heat exchange efficiency.

[0028] In this embodiment, a water supply pipe 28 is connected to the upper side of the water tank 23, and a water filter is installed on the water supply pipe 28. After the cooling water in the water tank 23 is pumped into the wet curtain 25, the water temperature is lower than the outdoor air temperature. The porous structure of the wet curtain 25 allows the outdoor air to fully contact and exchange heat with the spray water. Part of the spray water absorbs heat and evaporates. The cooled air with high humidity flows continuously to the condenser 21 under the drive of the condenser cooling fan 24. Therefore, the cooling water in the water tank 23 needs to be replenished in time. When the cooling water in the water tank 23 is too low, water can be added through the water supply pipe 28 to ensure that the water in the water tank 23 can completely submerge the recooler 22. In many areas, the water quality is poor. The water filter can reduce the possibility of impurities in the water corroding the recooler 22 or scale forming, which may affect the heat exchange effect of the recooler 22.

[0029] In this embodiment, the water supply pipe 28 is connected to a float switch 281, which is located on the upper inner side of the water tank 23. When the water level drops to the set lower limit, the float switch 281 contacts close, initiating water supply; when the water level rises to the set upper limit, the float switch 281 contacts open, stopping water supply and achieving automatic water level control.

[0030] In this embodiment, a drain pipe 29 is connected to the lower side of the water tank 23. When there is too much cooling water in the water tank 23, or when the water tank 23 needs to be cleaned or repaired, the cooling water can be drained away in time through the drain pipe 29 to prevent the cooling water from overflowing out of the water tank 23.

[0031] In this embodiment, the drain pipe 29 is connected to a drain valve switch 291. The drain valve switch 291 allows the user to open or close the drain pipe 29 at any time as needed, enabling flexible control.

[0032] In this embodiment, the recooler 22 is a coil immersed in the water tank 23. The structure of the coil increases the contact area between the recooler 22 and the cooling water in the water tank 23, significantly improving heat exchange efficiency and achieving a more efficient cooling effect.

[0033] In this embodiment, the recooler 22 is a coil made of 316 stainless steel. The 316 stainless steel material gives the recooler 22 excellent corrosion resistance, making it less prone to rust and scaling, reducing the frequency of maintenance and replacement, and extending its service life.

[0034] In this embodiment, an air duct is formed inside the outdoor unit 2. Within the air duct, a wet curtain 25, a condenser 21, and a condensing fan 24 are sequentially arranged. An air filter is installed at the air inlet of the air duct. This air duct allows cooling air to pass more effectively through the condenser 21 and the condensing fan 24, while the air filter effectively filters dust, pollen, bacteria, and other particulate matter from the air, reducing airborne pollutants and decreasing the likelihood of impurities falling into the water tank 23 with the sprayed water and affecting the heat exchange efficiency of the recooler 22. It also prevents impurities from clogging the condenser 21.

[0035] In summary, this type of multi-effect condensing evaporative cooling industrial air conditioner can solve the problem of low heat dissipation efficiency in traditional air conditioning systems in the existing technology.

[0036] Where there is no conflict, the above embodiments and features can be combined with each other.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
