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 and atomization, 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 CN202220770995X 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 and atomization, which 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 and atomization, comprising 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 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 component, which includes an oil filter, a water spraying mechanism, an atomizing component, 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 atomizing component is located above the main body of the water receiving tray. The water level detection sensor is located in the middle of the water receiving tray.

[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. Under the action of the water spraying mechanism and the atomizing component, the condensate is dispersed into water mist. The water mist exchanges heat fully with the condenser and is then drawn into the fan and discharged outdoors.

[0009] The oil filter is filled 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 and atomization processes.

[0010] The protruding part is provided with a water pump motor base. The water receiving tray is provided with two atomizer bases 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 pump motor base. The atomizing component includes two atomizers, which are respectively set on two atomizer bases and electrically connected to the control board.

[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. The water-spraying impeller is located at the end of the output shaft and above the water-spraying trough. The water-spraying motor is electrically connected to the control board.

[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 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.

[0014] The zero-drainage component improves the heat dissipation of the condenser and the efficiency of condensate drainage, achieving zero drainage.

[0015] The water level detection sensor is electrically connected to the control board, which enables automated control of the water dispensing mechanism and the atomizing component. The water level detection sensor can detect the water level in the water dispensing 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 dispensing mechanism and the atomizing component. Upon receiving the stop signal, the water dispensing mechanism and the atomizing component stop working.

[0016] The condenser has a protruding part at the lower end to increase the heat exchange area.

[0017] The water-spraying mechanism and the atomizing component can work simultaneously or independently.

[0018] Compared with existing technologies, the beneficial effects of this utility model are as follows: It incorporates a zero-drainage component, including an oil filter, a water-spraying mechanism, an atomizing assembly, and a water level sensor. 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 and atomization, 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, the structure is compact, energy-efficient, and operates stably, 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.
