Description

Technical Field

[0001] This utility model relates to the field of fresh air conditioning technology, and mainly to a fresh air conditioner with a condensate humidification structure. Background Technology

[0002] In modern building environments, air conditioning systems are widely used to regulate indoor temperature and air quality. Traditional air conditioners operate with a low evaporator surface temperature due to the temperature difference between indoors and outdoors. When warm, humid air flows over the evaporator, water vapor condenses into water droplets – this is called air conditioning condensate. Previously, the treatment of this condensate was rather rudimentary, typically involving a drip tray below the evaporator, from which the collected condensate was directly discharged outdoors through a drain pipe. However, the moisture in indoor air is essential for maintaining indoor humidity balance. This practice of discharging large amounts of condensate outdoors leads to significant moisture loss over time, resulting in lower indoor humidity, negatively impacting indoor comfort, and causing discomfort for both living and working environments. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a fresh air conditioner with a condensate humidification structure.

[0004] The specific technical solution is as follows:

[0005] A fresh air conditioner with a condensate humidification structure includes a body, one end of which is provided with a fresh air inlet and a return air inlet, and the other end is a supply air outlet; the body is provided with a filter assembly, a supply air fan and a cold water humidification device, and the supply air fan is located between the filter assembly and the cold water humidification device.

[0006] The filter assembly is located near the fresh air inlet and the return air inlet, and the two are used together; the cold water humidification device is located near the air supply outlet, and the two are used together.

[0007] The filter assembly includes a pre-filter, a medium-efficiency filter, and a high-efficiency filter. The pre-filter is installed near the fresh air inlet and the return air inlet, the high-efficiency filter is installed near the air supply fan, and the medium-efficiency filter is located between the pre-filter and the high-efficiency filter.

[0008] The cold water humidification device includes a first humidification component and a second humidification component. The first humidification component includes a first cold water tank and a first evaporator. The second humidification component includes a second cold water tank and a second evaporator. The first cold water tank is connected to the second cold water tank through a water tank connecting pipe.

[0009] Water-absorbing fibers are provided between the first cold shower tank and the second cold shower tank;

[0010] The first humidification component is located above the second humidification component, and the first evaporator and the second evaporator are arranged symmetrically about the first cold water tank as the axis of symmetry.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This patent describes a cold-spray humidification device for a fresh air conditioner with a condensate humidification structure. It can effectively utilize condensate to humidify the air. After the fresh air passes through a series of processes such as filtration, heat exchange, and cooling, it can fully absorb the condensate in the cold-spray tank when passing through the water-absorbing fibers, which significantly increases the air humidity and keeps the indoor environment at a relatively suitable humidity level. This effectively alleviates the dryness caused by prolonged operation of the air conditioner, creating a more comfortable and healthy indoor space for users. Whether living or working, users can feel more comfortable and reduce health problems such as respiratory discomfort caused by dry air.

[0013] 2. This patented fresh air conditioner with a condensate humidification structure utilizes a unique cold-spray humidification device design to recycle and reuse previously wasted air conditioning water. The first and second cold-spray water tanks are interconnected and work in conjunction with the evaporator, allowing the condensate water to be recycled during the humidification process. This not only reduces water waste but also lowers the risk of pipe blockages and leaks caused by frequent drainage, extending the lifespan of the air conditioner. From both environmental protection and equipment maintenance perspectives, this is significant, aligning with modern society's requirements for resource conservation and sustainable development. It also saves users the potential costs of repairing the air conditioner due to drainage issues.

[0014] 3. This patented fresh air conditioner with a condensate humidification structure utilizes primary, medium, and high-efficiency filters in its filter assembly to filter various pollutants such as dust, pollen, and bacteria from the air, effectively purifying the air entering the room and ensuring indoor air quality. Simultaneously, the cold water humidification device further cools the air during humidification due to the heat absorption characteristics of water evaporation, working in conjunction with the evaporator's cooling function to achieve more precise temperature and humidity regulation. This integrated design allows the air conditioner to comprehensively improve the indoor environment during operation, eliminating the need for users to purchase additional humidifiers or air purifiers. It simplifies the configuration of indoor environmental control equipment, providing users with a convenient and efficient indoor environment solution. Whether in the hot summer or the dry winter, it easily creates a fresh, comfortable, and temperature- and humidity-appropriate indoor environment. Attached Figure Description

The second humidification component 12 includes a second cold water tank 15 and a second evaporator 16.

[0026] Working principle:

[0027] Fresh air enters the unit through the fresh air inlet at the air intake port; it first passes through the pre-filter, which is mainly used to filter larger particles of impurities, such as dust and hair. If these large particles are not filtered out, they will affect the normal operation of subsequent equipment and reduce indoor air quality. Next, the air passes through the medium-efficiency filter, which can filter out medium-sized particles, such as some smaller dust particles and fibers, further purifying the air. Finally, the air passes through the high-efficiency filter, which can remove tiny particles, including bacteria, viruses and other microorganisms, as well as even smaller dust particles, ensuring that the air entering the heat exchange stage is relatively clean.

[0028] After filtration, the fresh air and return air undergo heat exchange. The return air is indoor air that has already been conditioned by air conditioning. The heat exchange process allows the temperature of the fresh air to approach the temperature of the indoor air, reducing the energy consumption of subsequent air conditioning temperature regulation. This process is achieved through a heat exchanger, which uses the temperature difference between the fresh air and return air to transfer heat from the side with a higher temperature to the side with a lower temperature. The air after heat exchange is then transported by a supply fan, which provides power to push the air to the next processing stage.

[0029] The air then undergoes a secondary cooling process through the evaporator, which is an important component of the refrigeration system. The refrigerant evaporates and absorbs heat in the evaporator, causing the temperature of the air flowing through it to decrease. This is based on the principle of the refrigeration cycle, where the refrigerant absorbs heat from the surrounding air and vaporizes under low pressure, thereby lowering the air temperature.

[0030] During the operation of the evaporator, as the air temperature decreases, the water vapor in the air will condense into water droplets. These water droplets are condensate. The condensate will collect in the first and second cold water tanks of the cold water humidification device. The first and second cold water tanks are connected by a water tank connecting pipe, so that the condensate can flow between the two tanks.

[0031] The absorbent fiber located between the two water tanks absorbs the condensation in the water tanks. When the air, after being cooled twice, flows through the absorbent fiber, the air carries away the moisture from the absorbent fiber, thus humidifying the air. The absorbent fiber acts like a sponge, storing moisture and releasing it into the air as it flows through.

[0032] After being humidified and cooled, the air is delivered into the room through the air outlet, thereby improving the indoor air humidity and temperature and providing a comfortable indoor environment.

[0033] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
