Description

Technical Field

[0001] This utility model relates to the field of evaporative cooling air conditioning technology, specifically to an evaporative cooling air conditioning refrigeration system. Background Technology

[0002] Evaporative cooling air conditioning technology is a technology that utilizes the heat absorption and cooling effect of water evaporation. Water has the ability to evaporate in the air. Under conditions without other heat sources, the heat and moisture exchange process between water and air involves the air transferring sensible heat to the water, causing the air temperature to drop. Due to water evaporation, the air's moisture content not only increases, but the water vapor entering the air also carries back some latent heat of vaporization. When these two types of heat are equal, the water temperature reaches the wet-bulb temperature of the air. As long as the air is not saturated, cooling can be achieved by directly spraying air with circulating water (or through a packing layer). When conditions permit, the cooled air can be used as supply air to lower the room temperature; this method of air treatment is called evaporative cooling air conditioning. Evaporative cooling air conditioning technology is classified into air-side evaporative cooling air conditioning technology and water-side evaporative cooling air conditioning technology according to the form of the output medium. This article mainly introduces air-side evaporative cooling air conditioning technology, which is an air conditioning technology that obtains cold air based on the principle of water evaporative cooling, using direct or indirect evaporative cooling methods or with mechanical refrigeration assistance. Water-side evaporative cooling is an air conditioning technology that obtains chilled water. Evaporative coolers with mechanical refrigeration assistance are also called "economizers." Air-side evaporative cooling air conditioning technology can be broadly categorized into two types: direct air-side evaporative cooling and indirect air-side evaporative cooling. Currently, direct air-side evaporative cooling technologies used in data centers primarily employ high-pressure micro-mist and packing materials, while indirect air-side evaporative cooling technologies mainly include tubular and dew-point systems. The advantages of direct air-side evaporative cooling include: large air volume, small enthalpy difference, high sensible heat cooling capacity, effective humidification in winter, and excellent dust filtration. The advantages of indirect air-side evaporative cooling include: no increase in air humidity, easy control of room cleanliness with full return air, and extended energy-saving operating time as an air heat exchanger. Considering the specific characteristics of data centers—high sensible heat, low latent heat, large air volume, small enthalpy difference, strict temperature and humidity requirements, high cleanliness requirements, and 365-day-a-year cooling—the advantages of air-side evaporative cooling technology largely align with the characteristics of data centers, thus meeting the requirements of data center applications.

[0003] The disadvantages of existing evaporative cooling air conditioners are: Existing evaporative cooling air conditioners are limited by the indoor air's heat and humidity, i.e., the enthalpy of the air, and generally operate above the wet-bulb temperature. Although indirect sensible heat evaporative cooling air conditioners have high cooling capacity, their cooling efficiency is low. Direct evaporative cooling, on the other hand, increases enthalpy and lowers temperature but cannot dehumidify; in fact, it may humidify. Furthermore, it has a relatively high thermal resistance, resulting in insufficient heat exchange and lower thermal efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an evaporative cooling air conditioning system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an evaporative cooling air conditioning system, comprising: a chassis body, wherein a fan, a condenser section, a filler material evaporative cooling channel, an air inlet, and an air outlet are respectively disposed within the chassis body, wherein the air inlet is disposed in the middle of the side wall of the chassis body, and the air outlet is disposed above the side wall of the chassis body away from the air inlet, the condenser section is respectively disposed at the top and bottom of the filler material evaporative cooling channel, the filler material evaporative cooling channel includes a first channel and a second channel, the first channel and the second channel are alternately distributed along the long side of the chassis body, the side wall of the first channel is composed of a cotton pad layer, polyurethane foam and silicone particles, the interior of the first channel is filled with a nano-aluminum ion solution and sealed by the polyurethane foam, and the second channel is formed by vacuuming and filling with superconducting liquid.

[0006] The fan draws outside air into the casing. In the dry channel, the air undergoes sensible heat exchange and cold radiation through heat pipes, then enters the room through the outlet. Dehumidification and cooling can reach sub-wet-bulb temperature. In the humid channel, the air's temperature and enthalpy increase, becoming high-temperature, saturated air before being discharged outdoors.

[0007] This air conditioning system utilizes heat pipe and solution absorption technologies for indirect evaporative cooling, resulting in energy savings and enhanced cooling efficiency. It also enables humidity control without requiring refrigerant phase change or the sensible heat exchange cycle of a compressor. It can lower the temperature and dehumidify to below 11.2 g / kg, meeting comfort air conditioning requirements. It reduces indoor latent heat load and operates at a supply air temperature lower than the indoor wet-bulb temperature (pressure wet-bulb temperature) for humidity control.

[0008] In one embodiment of this application, the condensation section includes an upper condenser pipe and a lower condenser pipe, which are connected by a coolant circulation pump.

[0009] In one embodiment of this application, the condensation section further includes a water inlet pipe and a drain pipe, wherein the water inlet pipe and the drain pipe are arranged parallel to each other on the side of the lower condenser pipe near the air inlet and extend from the side wall of the chassis body.

[0010] In one embodiment of this application, the air outlet may also be located on the top wall side of the chassis body away from the air inlet. Attached Figure Description

[0022] Please see Figures 1-4 An evaporative cooling air conditioning system includes: a chassis body 600, within which are respectively arranged a fan 100, a condensing section 400, a filler evaporative cooling channel 500, an air inlet 200, and an air outlet 300. The air inlet 200 is located in the middle of the side wall of the chassis body 600, and the air outlet 300 is located above the side wall of the chassis body 600 away from the air inlet 200. The condensing section 400 is located at the top and bottom of the filler evaporative cooling channel 500. The filler evaporative cooling channel 500 includes a first channel 501 and a second channel 502, which are staggered along the long side of the chassis body 600. The side wall of the first channel 501 is composed of a cotton pad layer, polyurethane foam, and silicone particles. The interior of the first channel 501 is filled with a nano-aluminum ion solution and sealed with polyurethane foam. The second channel 502 is formed by vacuuming and filling with superconducting liquid for sealing.

[0023] The first channel 501 (wet channel side) uses a cotton pad layer, polyurethane foam, and silicone granules. It is 5mm wide and 1m long, and can provide low-speed airflow: 0.2-1.6m / s (low-speed heat exchange is sufficient, thermal comfort is good, and energy saving is achieved).

[0024] The wet channel solution uses nano-aluminum ion solution to enhance heat conduction, heat exchange, and heat and mass transfer (enhancing refrigeration efficiency and cooling capacity). The concentration difference in the solution will enhance the convection and diffusion of heat and mass transfer according to Brownian motion law. However, the concentration should not be too high, as the increased viscous resistance will increase the flow resistance and increase the pump work.

[0025] The second channel 502 (dry channel side) is a heat pipe technology that involves evacuating and filling with superconducting liquid before sealing.

[0026] Working principle explanation:

[0027] Fan 100 draws outside air into the casing 600. The air undergoes sensible heat exchange and cold radiation through heat pipes in the dry channel, and enters the room through the air outlet 300. Dehumidification and cooling can reach sub-wet-bulb temperature. When the air temperature and enthalpy increase in the humid channel and it becomes high-temperature, humid, saturated air, it is discharged outdoors.

[0028] This air conditioning system utilizes heat pipe and solution absorption technologies for indirect evaporative cooling, resulting in energy savings and environmental friendliness. It enhances cooling efficiency and enables humidity control without requiring refrigerant phase change or the sensible heat exchange cycle of a compressor. It can lower the temperature and dehumidify to below 11.2 g / kg, meeting comfort air conditioning requirements. It reduces indoor latent heat load and operates at a supply air temperature lower than the indoor wet-bulb temperature (pressure wet-bulb temperature) for humidity control.

[0029] In some embodiments, the condensation section 400 includes an upper condenser pipe 401 and a lower condenser pipe 402, which are connected by a coolant circulation pump 403.

[0030] In some embodiments, the condenser section 400 further includes a water inlet pipe 404 and a drain pipe 405, wherein the water inlet pipe 404 and the drain pipe 405 are arranged in parallel on the side of the lower condenser pipe 402 near the air inlet 200 and extend from the side wall of the chassis body 600.

[0031] In some embodiments, the air outlet 300 may also be located on the top wall side of the chassis body 600 away from the air inlet 200.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
