Description

Technical Field

[0001] This invention relates to the field of temperature control technology for air conditioning cabinets, specifically to an energy-saving integrated air conditioning cabinet with condensate self-evaporation function. Background Technology

[0002] During the cooling operation of a cabinet air conditioner, condensation will continuously form on the surface of the evaporator.

[0003] Traditional cabinet air conditioners typically rely on external drain pipes to discharge condensate directly to the outdoors or sewers. This external discharge method is limited by the routing of drain pipes in installation scenarios such as base stations, rooftops, and the outdoors, resulting in problems such as inconvenient installation, easy pipe blockage, freezing and cracking in winter, and long-term dripping water corrosion of equipment foundations.

[0004] Some existing technologies attempt to use the heat of the condenser to evaporate condensate, but most of them use simple drip trays for natural evaporation or fixed flow rate dripping, which has low evaporation efficiency and lacks intelligent control. Under high humidity load conditions, problems such as condensate overflow, water accumulation, and secondary evaporation leading to increased humidity inside the cabinet are very likely to occur.

[0005] This leads to technical problems such as limited condensate drainage, lack of intelligent control over self-evaporation, and easy overflow under high humidity conditions. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide an integrated fresh air cabinet air conditioner with condensate self-evaporation and recycling, intelligent water level monitoring and dehumidification linkage control.

[0007] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an energy-saving integrated cabinet fresh air conditioner with condensate self-evaporation function, including a cabinet and a refrigeration cycle system installed in the cabinet, the refrigeration cycle system including an evaporator and a condenser, and also including a condensate collection unit installed below the evaporator and a condensate lifting unit connected to the condensate collection unit. The cabinet also includes a condensate collection chamber, an evaporative water distribution unit, a dehumidification unit, and an intelligent control unit. The condensate collection chamber is connected to the outlet of the condensate lifting unit, and the evaporation distribution unit is connected to the condensate collection chamber to guide the condensate to the surface of the condenser for evaporation. The dehumidification unit is connected to the area where the condenser is located, and discharges the water vapor generated by evaporation to the outside. The intelligent control unit detects the water level signal of the condensate collection unit and controls the start / stop of the condensate lifting unit and the water supply status of the evaporation distribution unit based on the detection results.

[0008] Preferably, the condensate collection unit includes a condensate drip tray and a guide pipe assembly; The condensate collection tray is located directly below the evaporator, with an outlet at its bottom. One end of the guide pipe assembly is connected to the outlet, and the other end is connected to the inlet of the condensate lifting unit.

[0009] Preferably, the condensate lifting unit includes a miniature water pump and a lifting pipeline; The inlet of the micro water pump is connected to the condensate collection unit, and the outlet is connected to the condensate collection chamber via a lift pipe.

[0010] Preferably, the evaporation water distribution unit includes a water distribution assembly and a water distribution network; The water distribution assembly is located above the condenser, with the outlet of the water distribution network facing the surface of the condenser, guiding the condensate to the surface of the condenser fins for evaporation.

[0011] Preferably, the dehumidification unit includes a dehumidification fan and a dehumidification duct; One end of the dehumidification duct is connected to the area where the condenser is located, and the other end is connected to the outside of the cabinet. The dehumidification fan is located inside the dehumidification duct and drives the humid air through the dehumidification duct to the outside.

[0012] Preferably, the intelligent control unit includes a water level sensor and a controller; The water level sensor is installed in the condensate collection unit to detect the condensate water level signal and transmit it to the controller. The controller controls the start and stop of the condensate lifting unit according to the water level signal. The condensate lifting unit is started when the water level reaches the preset upper limit and stopped when the water level drops to the preset lower limit.

[0013] Preferably, the intelligent control unit further includes a humidity sensor, which is located in the area where the condenser is located, detects the humidity signal of the area and transmits it to the controller; The controller controls the speed of the dehumidification fan in the dehumidification unit according to the humidity signal; When the humidity in the area exceeds the preset threshold, the water supply of the evaporative water distribution unit is suspended.

[0014] Preferably, the condensate collection chamber is also provided with an overflow outlet, which is connected to the drain outlet at the bottom of the cabinet through an overflow pipe; When the water level in the condensate collection chamber exceeds the overflow outlet height, the excess condensate is discharged through the overflow pipe.

[0015] The advantages of this invention compared to the prior art are: By collecting, lifting and distributing condensate water to the surface of the condenser for evaporation, no external drain pipe is required, which solves the problem of limited drainage and dripping water in traditional cabinet air conditioners. The intelligent control unit automatically adjusts the water level and distribution based on the water level signal to avoid condensate overflow and excessive water accumulation. The dehumidification unit promptly discharges the evaporated water vapor to the outside to prevent the humidity inside the cabinet from rising. The humidity sensor is linked with the dehumidification and water distribution systems, automatically adjusting under high humidity conditions to ensure stable and reliable self-evaporation. It achieves zero external discharge and recycling of condensate, and is flexible in installation, easy to maintain, and water-saving and environmentally friendly. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1-2 As shown, an energy-saving integrated cabinet fresh air conditioner with condensate self-evaporation function includes a cabinet and a refrigeration cycle system installed in the cabinet. The refrigeration cycle system includes an evaporator and a condenser, and also includes a condensate collection unit installed below the evaporator and a condensate lifting unit connected to the condensate collection unit. The cabinet also houses a condensate collection chamber, an evaporative water distribution unit, a dehumidification unit, and an intelligent control unit. The condensate collection chamber is connected to the outlet of the condensate lifting unit, and the evaporative water distribution unit is connected to the condensate collection chamber, guiding the condensate to the surface of the condenser for evaporation. The dehumidification unit is connected to the area where the condenser is located, discharging the water vapor generated by evaporation to the outside. The intelligent control unit detects the water level signal of the condensate collection unit and controls the start and stop of the condensate lifting unit and the water supply status of the evaporative water distribution unit based on the detection results.

[0020] In use, the condensate collection unit includes a condensate drip tray and a guide pipe assembly. The condensate drip tray is located directly below the evaporator and is funnel-shaped or shallow dish-shaped with an outlet at its bottom. One end of the guide pipe assembly is sealed to the outlet, and the other end is connected to the inlet of the condensate lifting unit. The condensate drip tray is used to collect the condensate dripping from the surface of the evaporator and guides the condensate to the condensate lifting unit through the guide pipe assembly. The condensate lifting unit includes a miniature water pump and a lifting pipeline; the inlet of the miniature water pump is connected to the guide pipe assembly, and the outlet is connected to the condensate collection chamber through the lifting pipeline. Among them, the miniature water pump is a low-head, small-flow submersible pump or diaphragm pump, which is installed at the bottom of the condensate drip tray or on the side wall of the cabinet to lift the condensate from a low position to the condensate collection chamber located above the condenser.

[0021] In one embodiment: The evaporation water distribution unit includes a water distribution component and a water distribution pipe network. The water distribution component is located above the condenser, and the outlet end of the water distribution pipe network faces the surface of the condenser. It guides the condensate in the condensate collection chamber to the surface of the condenser fins for evaporation. The water distribution pipe network can be a porous drip pipe or a microporous seepage pipe. The condensate evaporates rapidly into water vapor under the airflow generated by the condenser fan and the heating effect of the high temperature fins of the condenser. The dehumidification unit includes a dehumidification fan and a dehumidification duct. One end of the dehumidification duct is connected to the area where the condenser is located, and the other end is connected to the outside of the cabinet. The dehumidification fan is located in the dehumidification duct and drives the humid air through the dehumidification duct to the outside. The dehumidification duct is connected to the hot air area where the condenser is located to discharge the water vapor generated by the evaporation water distribution unit in a timely manner and avoid water vapor from circulating and accumulating in the cabinet.

[0022] In one embodiment: The intelligent control unit includes a water level sensor and a controller. The water level sensor is located inside the condensate collection unit, specifically on the side wall or bottom of the condensate drip tray, to detect the condensate water level signal and transmit it to the controller. The controller is a microcontroller or PLC controller, which controls the start and stop of the micro water pump according to the water level signal. When the water level reaches the preset upper limit, the micro water pump is started to lift the condensate to the condensate collection chamber. When the water level drops to the preset lower limit, the micro water pump is stopped to prevent the pump from running dry and condensate from overflowing. The intelligent control unit also includes a humidity sensor, which is located in the area where the condenser is located. The humidity sensor detects the humidity signal of the area and transmits it to the controller. The controller controls the speed of the dehumidification fan according to the humidity signal. When the humidity of the area increases, the speed of the dehumidification fan is increased to accelerate the dehumidification. When the humidity in the area exceeds the preset threshold, the controller will suspend the water supply of the evaporative water distribution unit, that is, close the water supply valve of the water distribution network or stop the micro water pump to prevent water vapor backflow caused by insufficient evaporation in high humidity environment.

[0023] For safety during use, in one embodiment: The condensate collection chamber is also equipped with an overflow outlet, which is located on the upper part of the side wall of the condensate collection chamber and connected to the drain outlet at the bottom of the cabinet through an overflow pipe. When the water level in the condensate collection chamber exceeds the height of the overflow outlet due to a malfunction of the evaporation water distribution unit or insufficient evaporation, the excess condensate is discharged from the cabinet through the overflow pipe as a safety precaution to prevent condensate from flowing back into the cabinet.

[0024] In a specific implementation of this invention, the cabinet air conditioner is in cooling operation, and the condensate generated on the surface of the evaporator drips into the condensate collection pan. The water level sensor detects the water level in real time. When the water level reaches the preset upper limit, the controller starts the micro water pump to pump the condensate to the condensate collection chamber through the lift pipeline. The condensate in the condensate collection chamber is evenly dripped onto the surface of the condenser fins through the water distribution network, and evaporates under the action of the condenser's heat dissipation airflow and high temperature. The dehumidification fan continuously exhausts humid air to the outside through the dehumidification duct; the humidity sensor monitors the humidity in the condenser area in real time, and when the humidity exceeds the threshold, the controller stops the water supply and increases the dehumidification; if the water level in the condensate collection chamber rises abnormally, the excess condensate is safely discharged through the overflow port and overflow pipe.
