detailed description

1 is a schematic structural view of a non-condensing water air conditioning system of the present application.

The air conditioner 1 is disposed on the cabinet 3, and the condensate treatment device 2 is also disposed on the cabinet and located below the air conditioner 1. The cabinet 3 is provided with a vent for air exchange with the air conditioner 1.

As shown in FIG. 1 , the air conditioner 1 includes an outer circulation fan 11 and an inner circulation fan 12 . The inner circulation fan 12 promotes air flow inside the cabinet 3 , and brings heat in the cabinet 3 to the air conditioner 1 , and the outer circulation fan 11 takes heat away. The hot air is formed, and the condensed water on the surface of the evaporator 21 is taken away during the blowing of the hot air.

The condensate treatment device 2 includes a water receiving box 20 and an evaporator 21, and the evaporator 21 is disposed in the water receiving box 20 Above, wherein the water receiving box 20 is configured to store condensed water generated by the air conditioner; the evaporator 21 is configured to suck the condensed water in the water receiving box 20 to the surface of the evaporator 21, The condensed water is evaporated.

Specifically, condensed water is generated during the operation of the air conditioner 1, and the condensed water drops on the evaporator 21. When the condensed water is small, it spreads directly on the surface of the evaporator 21, and when the air conditioner 1 stops working, the condensed water naturally evaporates; when the air conditioner 1 is in the running state, when the hot air blows down through the evaporator 21 The condensed water is quickly evaporated into water vapor and taken out by the external circulation fan 11. When the condensed water is large, the condensed water that is too late to be evaporated by the evaporator 21 is stored in the water receiving box 20. When the air conditioner 1 stops working, the evaporator 21 sucks the condensed water so that the condensed water reaches the upper surface of the evaporator 21 and naturally evaporates; when the air conditioner 1 is in operation, the evaporator also sucks the condensed water, so that the condensed water reaches evaporation. On the upper surface of the vessel 21, when hot air passes through the evaporator 21, the condensed water is quickly evaporated into water vapor and taken out by the outer circulation fan 11.

The non-condensing water air conditioning system provided by the embodiment of the present application comprises a condensed water treatment device, an air conditioner and a cabinet, wherein the condensed water treatment device comprises a water receiving box and an evaporator disposed on the water receiving box, and the water receiving box is used for storing the air conditioner The condensed water is generated, and the evaporator is used to suck the condensed water in the water tank to the surface of the evaporator so that the condensed water naturally evaporates when the air conditioner is not operating or causes the condensed water to evaporate through the air conditioner during the operation of the air conditioner. In the non-condensing water air conditioning system, the condensed water is treated by the condensed water treatment device to realize the non-condensed water discharge of the air conditioner, and there is no need to install a drainage pipe, thereby reducing the difficulty of construction. Moreover, the condensate treatment device evaporates the condensed water by natural evaporation or evaporates the condensed water through the air conditioner, and the condensed water is evaporated without excessive additional energy consumption and low energy consumption.

Optionally, referring to FIG. 1 , in an embodiment of the present application, the non-condensing water air conditioning system further includes an air conditioner cover 13 for sealing the air conditioner 1 and the condensed water treatment device 2 . The air conditioner cover 13 is provided with a simple sealing plate for facilitating maintenance of the condensate treatment device.

Next, the condensed water treatment apparatus described in the embodiment of the present application will be described in detail.

Specifically, the water receiving box 20 is made of a metal material such as stainless steel; or it may be made of a plastic material, a foam material or the like. The evaporator 21 is made of a porous material, and the surface of the porous material is coated with a water absorbing material, and the condensed water in the water receiving box 20 can be sucked up along the surface of the porous material, so that the evaporation area of the condensed water is geometrically increased. The embodiment of the present application does not limit the material of the evaporator 21, and may be made of an aluminum foil material, a copper material, or an aluminum material.

In the embodiment of the present application, the evaporator 21 is fixed in the water receiving box 20, and the evaporator 21 can be completely parallel with the water receiving box 20 without an angle therebetween; or, the evaporator 21 and the water receiving box 20 have a clip therebetween. At the corner, the partial projection of the evaporator 21 may be exposed to the water tank 20 or may not be leaked to the water tank 20. For example, referring to FIG. 1, the small triangle shown in the figure is the water receiving box 20, and the rectangular shape placed obliquely on the water receiving box is the evaporator 21 fixed on the water receiving box 20. Since the partial projection of the evaporator 21 is exposed to the water receiving box 20, the hot air of the air conditioner can reach a part of the lower surface of the evaporator 21, increasing the contact area of the hot air with the evaporator 21, thereby accelerating the evaporation speed of the condensed water on the evaporator 21. .

Optionally, in an embodiment of the present application, the condensed water treatment device further includes an evaporator holder 22, and the evaporator 21 is fixed on the water receiving box 20 by the evaporator holder 22.

In the above embodiment, when the cabinet equipment in the cabinet 3 is in a suitable environment or in a short time, it is in a bad situation. In the working environment, the air conditioner 2 operates less condensed water, and the evaporator 21 diffuses the condensed water to the upper surface of the evaporator 21. If the air conditioner 2 is in operation, the outer circulation fan 11 accelerates the air flow and is carried away by heat exchange. The heat in the cabinet 3 reduces the ambient temperature of the cabinet equipment. The heat taken away forms hot air. When the hot air passes through the evaporator 21, the condensed water on the surface of the evaporator 21 is quickly evaporated and discharged, taking away the heat in the surrounding air, further reducing the ambient temperature of the cabinet equipment. When the air conditioner 1 is stopped, if the condensed water is still stored in the water tank 20, the evaporator 21 can continue to suck the condensed water and naturally evaporate the condensed water.

However, when the cabinet equipment in the cabinet 3 is in a bad working environment for a long time, such as when the temperature is higher than 45 ° C and the humidity is higher than 95% for a long time, the condensed water generated by the operation of the air conditioner 2 is excessive, and the condensation water is evaporated. The rate is less than the rate at which the condensate is produced, and the condensed water that is too late to evaporate may even overflow the water tank 20. In order to prevent the condensed water from overflowing from the water receiving box 20, in the embodiment of the present application, referring again to FIG. 2 and FIG. 3, the condensed water treatment device 2 further includes: a liquid level sensor 23 and a heater 24; Embedded in the evaporator 21; the liquid level sensor 23 is disposed on the water receiving box 20 for triggering the heater when detecting that the condensed water in the water receiving box 20 reaches the warning water level The evaporator 21 is heated; or, for detecting that the condensed water in the water tank 20 falls below the warning water level, the heater 24 is triggered to stop heating the evaporator 21. The liquid level sensor 23 is mounted in the water tank 20 through the liquid level sensor mounting bracket 25, and the heater 24 is embedded in the evaporator 21.

When the liquid level sensor 23 detects that the condensed water in the water receiving box 20 reaches the warning water level line, the control board that triggers the cabinet apparatus turns on the heater 24, so that the heater 24 heats the evaporator 21 to accelerate the evaporation of the condensed water. When the liquid level sensor 23 detects that the condensed water in the water receiving box 20 falls below the warning water level line, the trigger control panel turns off the heater 24, so that the heater 24 stops heating the evaporator 21, after which the condensed water naturally evaporates or Evaporate through the air conditioner. Then, when the liquid level sensor 23 detects again that the condensed water in the water receiving box 20 reaches the warning water level line, the control board that triggers the cabinet device turns on the heater 24, thus circulating. Specifically, referring to FIG. 4, FIG. 4 is a flowchart of processing condensed water of the condensed water treatment device of the present application, including:

101. Air conditioning operation produces condensed water.

106. Control the board to turn off the heater;

107. The condensed water is naturally evaporated or evaporated by the air conditioner and returned to 102.

In this embodiment, the heater is embedded in the evaporator, and the heater does not work under normal conditions. Only under extreme working conditions, when the condensed water reaches the warning water level line, the liquid level sensor triggers the heater to accelerate the evaporation of the condensed water. Moreover, the power of the heater is small.
