Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning condensers, and in particular to a heat and moisture exchange device and method for an evaporative cooling air-conditioning condenser. Background Art

[0002] The usual evaporative heat exchanger used as a condenser uses water to spray directly on the surface of the copper tube to absorb the heat released by the working fluid. Although its efficiency is higher than that of an air-cooled or water-cooled heat exchanger, the water cannot be evenly distributed on the surface of the copper tube. If there are water droplets or a large amount of water remaining on the surface of the copper tube, the evaporation effect will be greatly reduced, that is, the efficiency will be reduced.

[0003] In addition, the traditional spraying method usually uses a nozzle. Since the heat exchanger is used outdoors for a long time, the water outlet of the nozzle is easily blocked by impurities and affects normal use. In addition, the nozzle method cannot be evenly distributed on the surface of the copper tube, and a large amount of water will be stored in the channel of the copper tube, which not only affects the evaporation effect, but also increases the energy consumption of the fan, which is not conducive to energy saving and environmental protection. For this reason, we propose a heat and moisture exchange device and method for a cooling air conditioner condenser to solve the above-mentioned problems. Summary of the invention

[0034] Reference Figure 1-Figure 6 , provides an evaporative cooling air conditioner condenser heat and moisture exchange device, comprising:

[0035] The condenser structure 100 includes a condenser shell 101 and a plurality of heat exchanger pipes 102 arranged inside the condenser shell 101. A fan unit is arranged at the upper end of the condenser shell 101, and a water baffle 103 corresponding to the fan unit is arranged on the top wall of the condenser shell 101. Specifically, the fan unit includes an axial flow fan 104 arranged at the upper end of the condenser shell 101, and a protective cover is arranged on the outer side of the axial flow fan 104. The axial flow fan 104 is connected to the inside of the condenser shell 101, and the water baffle 103 is arranged correspondingly on the lower side of the axial flow fan 104.

[0036] The water distribution structure 200 includes a water storage chamber which is arranged at the lower side of the heat exchanger pipe 102 and has a water storage function. A water pump 201 is fixedly connected in the condenser shell 101 on one side of the water storage chamber. The input end of the water pump 201 is connected to the water storage chamber through the water inlet pipe 202, and the output end of the water pump 201 is fixedly connected to the water outlet pipe 203. The output end of the water outlet pipe 203 is horizontally arranged at the front side of the heat exchanger pipe 102, and a plurality of water outlet branches 204 perpendicular to the water outlet pipe 203 are evenly connected on the side wall of the water outlet pipe 203. The water outlet branch pipe 204 extends to the upper side of the heat exchanger pipe 102 and is connected to a water distribution unit. The water distribution unit can evenly scatter water droplets on the heat exchanger pipe 102 and avoid the heat exchanger pipe 102 There are water droplets between the lanes. Specifically, the water distribution unit includes a plurality of curved pipes 205 fixedly connected to the upper end of the water outlet branch pipe 204. The water outlet end of the curved pipe 205 is arranged downward. Rectangular frames 206 are fixedly connected to the inner walls of the condenser shell 101 on both sides of the water outlet branch pipe 204. The lower end of the rectangular frame 206 is provided with a plurality of water distribution holes 207 opposite to the water outlet end of the curved pipe. The water falling from the water outlet end of the curved pipe 205 will fall on the plurality of water distribution holes 207 and complete dripping. Compared with the traditional nozzle-type spraying method, the design of the curved pipe 205 can avoid the blockage of the nozzle outlet. Since the condenser shell is in outdoor work for a long time, the nozzle is exposed to the outside, which will allow external impurities to enter and affect the stable use of the nozzle.

[0037] Furthermore, multiple water distribution holes 207 are arranged in a rectangular shape, and the design of the elbow 205 prevents impurities from entering the water outlet end of the elbow 205 to ensure stable water outlet. Water dripping from the water distribution holes 207 will fall from the heat exchanger pipe 102, and there will be no water droplets between the lanes of the heat exchanger pipe 102. The water droplets can be fully scattered on the heat exchanger pipe 102 to reduce the energy consumption of the fan unit. The rectangular arrangement of water replenishment allows water droplets to accurately fall from the heat exchanger pipe 102 without falling into the lane, and the fan unit will not consume energy to process the water vapor in the lane, thereby reducing energy consumption and achieving energy saving and environmental protection.

[0038] Among them, a water replenishment unit is arranged in the water storage chamber, and the water replenishment unit includes a float 208 arranged in the water storage chamber, the float 208 is connected to a pressure relief valve through a connecting rod, and a water replenishment pipe is connected to the outside of the pressure relief valve. When the water level in the water storage chamber is low, the float 208 decreases with the water level, and the piston in the pressure relief valve is pulled outward through the connecting rod of the float 208, so that a gap is generated between the valve body and the piston of the pressure relief valve, so that tap water can enter the water storage chamber. Specifically, a sewage pipe connected to the outside is fixedly connected to the bottom wall of the water storage chamber, and a sewage valve is fixedly connected to the outer wall of the sewage pipe. A filter is connected to the side wall of the water inlet pipe 202 between the water storage chamber and the water pump 201, and the filter is used to separate impurities in the water inlet pipe 202. A control box 209 is arranged in the condenser shell 101, and a controller connected to the water pump 201, the pressure relief valve and the sewage valve is arranged in the control box 209.

[0039] The heat and moisture exchange method of the evaporative cooling air conditioner condenser comprises the following steps:

[0040] Step 1: The superheated refrigerant gas discharged from the compressor in the air-conditioning system enters the condenser housing 101, and the water in the water storage chamber is passed from the water outlet pipe 203 to the water outlet branch pipe 204 through the water pump 201;

[0041] Step 2: Water is uniformly dripped into the rectangular frame 206 through the multiple elbows 205 evenly arranged on the water outlet branch pipe 204, and the water falls from the multiple rectangularly arranged water distribution holes 207 and is fully scattered on the heat exchanger pipe 102, and there are no water drops between the lanes of the heat exchanger pipe 102, so as to reduce the energy consumption of the fan unit;

[0042] Step 3: When the water level in the water storage chamber is low, the float 208 drops with the water level, and the connecting rod of the float 208 drives the piston in the pressure relief valve to be pulled outward, so that a gap is generated between the valve body and the piston of the pressure relief valve, allowing tap water to enter the water storage chamber, playing a role in water replenishment and ensuring that the water pump can continue to work.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
