Description

Technical Field

[0001] This utility model relates to a heat exchange system for an air conditioning system, and more particularly to a zero-drainage air conditioning heat exchange system with water pumping, atomization and spraying, belonging to the field of air conditioning technology. Background Technology

[0002] With the improvement of people's living standards, kitchen air conditioners have become an indispensable appliance in modern homes. Traditional air conditioning systems mostly rely on fan coil units for cooling or heating, but they suffer from problems such as high energy consumption, low cooling efficiency, and easy condensation buildup. To solve these problems, air conditioning heat exchange systems that combine water pumping motors have emerged on the market. These systems can disperse the condensate flowing through the gaps between the condenser finned tubes into water mist, exchange heat with the condenser, and then be drawn into the fan and discharged outdoors.

[0003] For example, the patent technology entitled "Water Dispensing Device and Portable Air Conditioner" with publication number CN 217685810 U and application number CN202220770995.X discloses the following technical solution: The water dispensing device includes a base and a water dispensing module. The base forms a water receiving trough and a water dispensing trough. The water dispensing module includes a water dispensing motor and a water dispensing impeller connected to the output shaft of the water dispensing motor. The water dispensing impeller is used to spray the condensate in the water dispensing trough to the condenser at a preset angle.

[0004] However, in the aforementioned patented technology, if used in kitchen air conditioners, the condensate water is not purified, containing oil and solid particles, resulting in poor fluid quality and pollution of fresh air. The condenser's heat dissipation efficiency and condensate drainage efficiency both need improvement. Furthermore, the drip tray and base are installed separately, making leaks likely, and the manufacturing and installation process is complex, time-consuming, and material-intensive. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing air conditioning heat exchange systems, such as the presence of oil and solid particles in the condensate, which pollutes the fresh air, and the need to improve the heat dissipation effect of the condenser and the efficiency of condensate drainage; as well as the time-consuming and material-intensive installation of the drip tray. This invention provides a zero-drainage air conditioning heat exchange system with water pumping, atomization, and spraying functions. This system achieves the goals of purifying the condensate to remove oil and solid particles, improving the heat dissipation effect of the condenser, achieving zero condensate discharge, and integrating the drip tray and base.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a zero-drainage air conditioning heat exchange system with water pumping, atomization, and spraying, including a chassis, a condenser, a fan, an evaporator, and a control board. The condenser includes a condenser finned tube assembly, and the evaporator includes an evaporator finned tube assembly. The chassis includes a water collection tank on the right and a water receiving tray on the left. Several water guide channels are symmetrically arranged on the front and rear sides of the water collection tank, which receives the condensate generated by the evaporator. The water receiving tray includes a main body and a forward protrusion, and the water receiving tray is connected to the water collection tank. The condenser is fixedly installed above the main body of the water receiving tray, and the evaporator is fixedly installed above the water collection tank. The evaporator and condenser are arranged sequentially according to the water flow direction, and the fan is located behind the condenser. When external air enters the air conditioner and passes through the evaporator, condensate is generated on the outer surface of the evaporator finned tube assembly due to the temperature difference. The condensate drips downward under the action of gravity, flows through the water guide channels to the water collection tank, and then flows to the water receiving tray.

[0007] It also includes a zero-drainage assembly; the zero-drainage assembly includes an oil filter, a water-spraying mechanism, a spraying mechanism, an atomizer assembly, and a water level detection sensor; the oil filter is located in the middle of the chassis, between the water collection tank and the water receiving tray; the water-spraying mechanism is located above the water receiving tray and between the condenser finned tube assembly; the spraying mechanism is located on the water receiving tray and on the condenser; the atomizer assembly is located above the water receiving tray; and the water level detection sensor is located in the middle of the chassis;

[0008] The condensate produced by the evaporator flows into the water collection tank through the water guide channel and is filtered by the oil filter; the water spraying mechanism disperses the condensate into water mist; the spraying mechanism sprays the condensate evenly from top to bottom onto the condenser finned tube assembly, absorbing the heat released by the condenser and quickly evaporating it into water vapor; the atomizer assembly atomizes the water into water mist, and the water mist and water vapor undergo sufficient heat exchange with the condenser, and are then drawn into the fan and discharged outdoors;

[0009] The protruding part is provided with a water pumping motor base, and the water receiving tray is provided with a water pumping base, an atomizer base and a water pumping trough in the middle from left to right; the position of the water pumping trough corresponds to the position of the water pumping motor base.

[0010] The oil filter is equipped with filter cotton. The oil filter removes oil, solid particles, and suspended matter from the condensate, thereby improving fluid quality and preventing pollution of fresh air during subsequent water spraying, atomization, and misting processes.

[0011] The water-spraying mechanism includes a water-spraying motor, a motor output shaft, and a water-spraying impeller. The water-spraying motor is mounted on a water-spraying motor base, the motor output shaft is located inside the water-spraying motor and extends inward, and the water-spraying impeller is located at the end of the output shaft above the water-spraying trough.

[0012] Driven by a water-pumping motor, the impeller rotates, dispersing the condensate flowing through the gaps between the condenser finned tubes into a mist. This mist allows for thorough heat exchange with the condenser finned tubes, before being drawn into the fan and discharged outdoors by the airflow. This achieves effective condensate drainage, efficient utilization of condensate, and high water conservation. The evaporation of the water mist absorbs a large amount of heat, improving the condenser's heat dissipation and heat conversion efficiency, thus enhancing the system's cooling efficiency. The dispersed water mist also reduces the accumulation of condensate on the finned tubes, preventing bacterial growth and improving indoor air quality.

[0013] The spraying mechanism includes a water pump, two spray heads, and a water pipe; the condenser includes a condenser support, the water pump is located in the middle left side of the condenser support, and the two spray heads are positioned downwards at the top of the condenser support; the water pump and the two spray heads are connected by a water pipe, the lower end of which is inserted into a water receiving tray.

[0014] After the water pump is started, the condensate is drawn through the water pipe to the spray head, and then sprayed evenly from top to bottom onto the condenser finned tube assembly. The condensate absorbs the heat released by the condenser finned tube assembly and quickly evaporates into water vapor, which is then discharged under the drive of the fan. This promotes rapid heat dissipation of the condenser, achieves a better condensate discharge effect, and improves the heat dissipation effect and heat conversion efficiency of the condenser.

[0015] The atomizer assembly includes two atomizers and two atomizer bases; the two atomizers are respectively mounted on the two atomizer bases.

[0016] The atomizer atomizes the condensate in the water pan. When the fan is working, the negative pressure automatically draws the water mist away. The water mist passes through the condenser and is discharged, promoting air circulation, carrying away some of the heat from the condenser, enhancing the heat exchange between the air and the condenser, improving the heat dissipation effect of the condenser, and thus further improving the condensate discharge efficiency.

[0017] The zero-drainage component allows water mist and vapor to fully exchange heat with the condenser before being drawn into the fan and discharged outdoors; this improves the heat dissipation effect of the condenser and the efficiency of condensate drainage, achieving zero drainage.

[0018] The water level detection sensor, water spraying mechanism, spraying mechanism, and atomizer assembly are all connected to the control board, which realizes the automated control of the water spraying mechanism, spraying mechanism, and atomizer assembly. The water level detection sensor can detect the water level in the water tank. When the water level detection sensor detects that the water level is low and no drainage is required, it sends a stop signal to the water spraying mechanism, spraying mechanism, and atomizer assembly. Upon receiving the stop signal, the water spraying mechanism, spraying mechanism, and atomizer assembly stop working.

[0019] The condenser has a protruding part at the lower end to increase the heat exchange area.

[0020] The water spraying mechanism, spraying mechanism, and atomizer assembly can work simultaneously or independently.

[0021] Compared with existing technologies, the beneficial effects of this utility model are as follows: It combines an oil filter, a water spraying mechanism, a spraying mechanism, an atomizer assembly, and a water level sensor to form a zero-drainage component. This ensures that the condensate is purified, free of oil and solid particles, thereby improving fluid quality and ensuring that fresh air is not contaminated. Through water spraying, atomization, and misting, the heat dissipation effect of the condenser and the condensate drainage efficiency are further improved, achieving zero condensate discharge and guaranteeing the cooling efficiency, water-saving performance, and operational stability of the air conditioning system. Furthermore, it features a compact structure, high energy efficiency, and stable operation, improving the overall performance of the air conditioning system. The drip tray and base are integrated, preventing leaks and facilitating installation. Utilizing condensate for cooling saves energy, reduces power consumption, eliminates the need for a drain pump, lowers the risk of leakage, and responds to energy conservation and emission reduction initiatives.

The condenser 2 includes a condenser finned tube assembly 201, and the evaporator 3 includes an evaporator finned tube assembly 301. The chassis 1 includes a water collection tank 6 on the right and a water receiving tray 7 on the left. The water collection tank 6 has several water guide channels 601 symmetrically arranged on its front and rear sides, and receives the condensate produced by the evaporator 3. The water receiving tray 7 includes a tray body 701 and a forward protrusion 702. The water receiving tray 7 and... The water collection tank 6 is connected; the condenser 2 is fixedly installed above the water receiving tray 701, and the evaporator 3 is fixedly installed above the water collection tank 6. The evaporator 3 and the condenser 2 are arranged in sequence according to the water flow direction. The fan (not shown in the figure) is located behind the condenser 2. After the outside air enters the air conditioner and passes through the evaporator 3, condensate is generated on the outer surface of the evaporator finned tube assembly 301 due to the temperature difference. The condensate drips down under the action of gravity, flows through the water guide 601 to the water collection tank 6, and then flows to the water receiving tray 7.

[0032] like Figure 5 As shown, it also includes a zero-drainage assembly; the zero-drainage assembly includes an oil filter 8, a water-spraying mechanism 9, a spraying mechanism 10, an atomizer assembly 11, and a water level detection sensor 5; the oil filter 8 is located in the middle of the chassis 1, between the water collection tank 6 and the water receiving tray 7; the water-spraying mechanism 9 is located above the water receiving tray 7 and between the condenser finned tube assembly 201; the spraying mechanism 10 is located on the water receiving tray body 701 and the condenser 2; the atomizer assembly 11 is located above the water receiving tray body 701; the water level detection sensor 5 is located in the middle of the chassis;

[0035] like Figures 3 to 7 As shown, the oil filter 8 is filled with filter cotton. The oil filter 8 removes oil, solid particles, and suspended matter from the condensate, thereby improving fluid quality and preventing pollution of fresh air during subsequent water spraying, atomization, and misting processes.

[0036] like Figures 3 to 7 As shown, the water-spraying mechanism 9 includes a water-spraying motor 901, a motor output shaft 902, and a water-spraying impeller 903. The water-spraying motor 901 is mounted on the water-spraying motor base 904. The motor output shaft 902 is located inside the water-spraying motor 901 and extends inward. The water-spraying impeller 903 is located at the end of the output shaft and above the water-spraying trough 905.

[0037] Driven by the water-pumping motor 901, the impeller 903 rotates, dispersing the condensate flowing through the gaps in the condenser finned tube assembly 201 into water mist. This water mist then undergoes thorough heat exchange with the finned tube assembly of the condenser 2, before being drawn into the fan and discharged outdoors by the airflow. This achieves a good condensate drainage effect, realizing effective utilization of condensate and high-efficiency water saving. The evaporation of the water mist absorbs a large amount of heat, improving the heat dissipation effect and heat conversion efficiency of the condenser 2, and enhancing the cooling efficiency of the system. The dispersed water mist reduces the accumulation of condensate on the finned tubes, preventing bacterial growth and improving indoor air quality.

The condensate absorbs the heat released from the condenser finned tube assembly 201 and quickly evaporates into water vapor, which is discharged under the drive of the fan. This promotes the rapid heat dissipation of the condenser 2, achieves a better condensate discharge effect, and improves the heat dissipation effect and heat conversion efficiency of the condenser 2.

[0040] like Figures 3 to 7 As shown, the atomizer assembly 11 includes two atomizers 1101; the two atomizers 1101 are respectively disposed on two atomizer bases 1102;
