Description

Technical Field

[0001] This utility model relates to an energy-saving air conditioner, specifically an air conditioning device that utilizes the complete vaporization of water for refrigeration, belonging to the fields of energy-saving technology and HVAC technology. Background Technology

[0002] During hot seasons, the main types of air conditioners used are compressor-based air conditioners and evaporative cooling systems. Compressor-based air conditioners offer better cooling and comfort but are more energy-intensive, while evaporative cooling systems consume less electricity but are less effective and do not provide the same level of comfort. In environments with poor sealing or requiring extensive ventilation, the high electricity cost of compressor-based air conditioners leads to the widespread adoption of evaporative cooling systems, particularly in large industrial plants.

[0003] Traditional water curtain air conditioners mostly use honeycomb paper (layered corrugated paper) for heat exchange. Water is sprayed onto the honeycomb paper to wet it, allowing air to pass through the gaps and cool the air. While the wet honeycomb paper evaporates moisture and absorbs heat from the air as air passes through, a relatively large airflow is needed to effectively evaporate enough moisture. This large airflow means the cooling capacity contributed by water evaporation is insufficient to meet the cooling demand of the large air volume. In other words, the low ratio of water evaporation to airflow is a major reason for the poor cooling effect of traditional water curtain air conditioners. Using non-frozen, room-temperature water for sensible heat exchange is also ineffective due to the small temperature difference between water and air. Furthermore, after the water pump circulates for a certain period, the water slowly absorbs heat from the airflow. This accumulated heat gradually raises the temperature of the sprayed water, further reducing the temperature difference between the sprayed water and the incoming air. Ultimately, sensible heat exchange decreases, leading to a further reduction in cooling performance.

[0004] Traditional water curtain air conditioners have extremely limited cooling effects due to the sensible heat exchange of water. Therefore, a large air volume is required to increase the evaporation of water and achieve the latent heat cooling effect. However, as mentioned above, a large air volume cannot significantly cool the air. Furthermore, an excessively large air volume is unsuitable in many situations. In factories, it can easily blow away or even scatter lightweight materials such as paper, film, cloth, yarn, and foam. It is also unsuitable for use in places with flour, cement powder, sawdust, etc., as these powdery and fine particulate matter will cause dust when exposed to strong winds. Even when used for cooling in restaurants, a large air volume blowing directly at customers can cause discomfort.

[0005] The honeycomb paper used in existing water curtain air conditioners is prone to mold and rot after a few years of use. After being out of use for a period of time, it will accumulate dust and easily become a breeding ground for bacteria and pests, which will affect the health of users when used again. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an energy-saving air conditioner that is smaller in size for the same cooling capacity, can be made into a thinner model, and has a longer service life.

[0007] The present invention can adopt the following technical solution:

[0008] An energy-saving air conditioner includes a housing, an air inlet, a sintered honeycomb structure, a sprayer, a water pump, an air outlet, and a fan. The air inlet is located at the upper or lower part of the housing, and the air outlet is located on the front surface of the housing. The sintered honeycomb structure, the sprayer, and the water pump are located inside the housing. The fan is located inside the air inlet of the housing, or the fan is an external fan located outside the housing, connected to the air inlet via an air duct. The sintered honeycomb structure is vertically installed in the air passage area between the air inlet and the air outlet, allowing air entering from the air inlet to pass through the honeycomb holes of the sintered honeycomb structure before flowing out from the air outlet. The sprayer is located on the windward side of the sintered honeycomb structure. The water inlet of the sprayer is connected to the water outlet of the water pump via a pipe.

[0009] The following improvements can be further implemented to solve the problem of this utility model:

[0010] Further improvements include: an inclined guide plate is provided in the air passage area, which is located in front of the windward side of the sintered honeycomb body. The guide plate and the windward side of the vertical sintered honeycomb body form a V-shaped air passage that is wider at the top and narrower at the bottom. The air inlet is connected to the upper opening of the V-shaped air passage.

[0011] Further improvements include: a gap 1 is left at the bottom of the V-shaped air duct to allow excess spray water to flow into the water storage area below; a gap 2 is left between the bottom of the air outlet surface of the sintered honeycomb body and the shell to allow water flowing down from the air outlet surface of the sintered honeycomb body to flow into the water storage area below.

[0012] Further improvements include: the fan is located inside the air inlet of the housing, the fan's suction port is connected to the air inlet of the housing, and the fan's outlet is connected to the upper opening of the V-shaped air duct.

[0013] Further improvements include: a water storage area is provided below the housing; the water pump's suction port is located at the bottom of the water storage area; the sprayer's inlet is connected to the water pump's outlet via a pipe; the water storage area is equipped with a water injection pipe, and the water level in the water storage area is controlled by a float valve on the water injection pipe.

[0014] Further improvements include: sintered honeycomb structures are made by sintering zeolite molecular sieve materials, carbon molecular sieve materials, or microporous ceramic materials. Molecular sieve materials have well-developed pore structures and large specific surface areas, as well as good water absorption and weather resistance.

[0015] A further improvement is that the sintered honeycomb structure is mounted on and fixed to a support frame. This ensures that the sintered honeycomb structure will not fall or be damaged during handling or tipping.

[0016] Further improvements include: the sprayer can be a flat spray nozzle or a multi-hole spray pipe, and the number of sprayers can be one or more, located above the windward side of the sintered honeycomb or distributed from top to bottom.

[0017] A further improvement is that the air outlet is equipped with louvers, which are mounted on the housing.

[0018] The above technical solution has the following technical effects:

[0019] 1. The air inlet of this utility model is located at the upper part of the housing, and the air outlet is located on the front face of the housing. This allows for the creation of a thinner structure, resulting in a smaller footprint.

[0020] 2. The heat exchange material of this utility model adopts sintered honeycomb, which has excellent weather resistance. The sintered honeycomb material is entirely inorganic or fixed carbon, which is not easy to breed bacteria and rot, and has a long service life.

[0021] 3. Compared with water curtain air conditioners, this utility model has a smaller size under the same cooling capacity and can be made into a thinner model, which takes up less space. In particular, it is more conducive to the layout of the space and is more aesthetically pleasing when placed against the wall. The thin structure brings a lot of convenience to product application development. It can be made into a small tabletop model or a huge wall structure, becoming a fixed or movable "cold air wall" for indoor or outdoor air cooling.

[0022] 4. Compared with water curtain air conditioners, the honeycomb molecular sieve material has a stronger capillary moisture diffusion function than honeycomb paper. In particular, the contact area between water and air increased by the huge specific surface area of ​​the former is several orders of magnitude higher than that of the latter. Under the same air volume, the rate of water evaporation can be greatly improved, and the transfer of a large amount of latent heat of water evaporation can greatly increase the cooling efficiency.

[0023] 5. The refrigeration process of this utility model does not require the compressor to work, thus saving energy. It does not use chemical refrigerants, which reduces environmental pollution.

[0024] 6. The heat exchange material of this utility model is in a sealed box, which will not accumulate dust and pests will have difficulty entering, ensuring that the air is not contaminated.

[0032] The present invention will now be described in detail with reference to specific embodiments.

[0033] Example 1: As Figure 1 and Figure 2 As shown, an energy-saving air conditioner includes a housing 1, an air inlet 2, a sintered honeycomb structure 7, a sprayer 10, a water pump 9, an air outlet 3, and a fan 6. The air inlet 2 is located at the upper part of the housing 1, and the air outlet 3 is located on the front of the housing 1. The sintered honeycomb structure 7, the sprayer 10, and the water pump 9 are located inside the housing 1. The fan 6 is located inside the air inlet 2 of the housing 1. The sintered honeycomb structure 7 is installed in a wall-like structure and stands upright in the air passage area between the air inlet 2 and the air outlet 3, allowing the air entering from the air inlet 2 to pass through the honeycomb holes of the sintered honeycomb structure 7 before flowing out from the air outlet 3. The sintered honeycomb structure 7 is a molecular sieve honeycomb block with good water absorption. The sprayer 10 is located on the windward side of the sintered honeycomb structure 7. The water inlet of the sprayer 10 is connected to the water outlet 91 of the water pump 9 through a pipe.

[0034] In this example, the housing 1 has a water storage area 8 at its bottom; the water inlet of the water pump 9 is located at the bottom of the water storage area 8; the water inlet of the sprayer 10 is connected to the water outlet 91 of the water pump 14 through a pipe; the water storage area 8 is provided with a water injection pipe 4, and the water level 81 of the water storage area is controlled by a float valve 41 on the water injection pipe 4.

[0035] In this example, the sintered honeycomb 7 is made by sintering zeolite molecular sieve material. Molecular sieve material has a well-developed pore structure and a huge specific surface area, as well as good water absorption and weather resistance.

[0036] In this example, the sintered honeycomb 7 is mounted on and fixed on the support frame 71 to ensure that the sintered honeycomb 7 will not fall and be damaged during handling or tilting.

[0037] In this example, the sprayer 10 is a multi-layer flat spray nozzle, which is located on the windward side of the sintered honeycomb body 7 and distributed from top to bottom.

[0038] In this example, the air passage area is equipped with an inclined guide plate 11, which is located in front of the windward face of the sintered honeycomb body 7. The guide plate 11 and the windward face of the vertical sintered honeycomb body 7 form a V-shaped air passage 12 that is wider at the top and narrower at the bottom. Its function is to prevent the fan's air force from acting on the lower part of the vertical air passage, which would cause the air volume entering the sintered honeycomb body from the horizontal direction to be uneven from top to bottom. The V-shaped air passage, which is wider at the top and narrower at the bottom, can ensure that the airflow from the sintered honeycomb body is relatively uniform from top to bottom.

[0039] In this example, the bottom of the V-shaped air duct 12 has a gap 13, which allows excess spray water to flow into the water storage area 8 below; the bottom of the air outlet surface of the sintered honeycomb body 7 and the shell 1 have a gap 14, which allows water flowing down from the air outlet surface of the sintered honeycomb body 7 to flow into the water storage area 8 below.

[0040] In this example, the fan 6 is located inside the air inlet 2 of the housing 1. The air intake of the fan 6 is connected to the air inlet 2 of the housing 1, and the air outlet of the fan 6 is connected to the upper opening of the V-shaped air duct 12.

[0041] In this example, the air outlet 3 of the housing 1 is provided with louvers 31, which are installed on the housing 1.

[0042] Working principle:

[0043] Example 1 (with appendix) Figure 1 and 2 The working process of this utility model is as follows: the water inlet pipe is connected to the external tap water, the water inlet volume is controlled by the float valve, or water is added through the manual water inlet. The water level in the water storage area is always kept near the water level line (81). Then the fan and water pump are started, and the water sprayer sprays water onto the windward side of the zeolite molecular sieve sintered honeycomb body. The water will enter the interior of the sintered honeycomb body with the help of the wind and be absorbed. The excess water sprayed will flow back into the water storage area from the gap under the guide plate. Long-term spraying or intermittent spraying can be used. It is only necessary to keep the sintered honeycomb body moist. Driven by the fan, the external air enters from the air inlet and passes through the honeycomb holes of the zeolite molecular sieve sintered honeycomb body before being discharged, thus completing the cooling of the air flowing through.

[0044] The refrigeration principle of this invention is as follows: Air flowing through the honeycomb microchannels of zeolite molecular sieves desorbs moisture absorbed into the zeolite molecular sieve material. After desorption, the moisture forms water vapor and is carried out by the air. During the desorption process, the water vapor absorbs heat as it evaporates. Because the zeolite molecular sieve honeycomb has a large air passage area and the molecular sieve material has an extremely high specific surface area, coupled with the open microporous structure of the molecular sieve material, the dense capillaries formed from the inside out accelerate the permeation of internal moisture to the outside. The combined effect of these factors can significantly improve the vaporization efficiency of moisture in the molecular sieve. When the moisture in the zeolite molecular sieve comes into contact with air, it quickly desorbs and forms water vapor. Although the temperature of the water vapor after the phase change does not change, the latent heat required for the phase change of water vapor vaporization is obtained by absorbing the sensible heat in the moist sintered honeycomb body. In other words, when the desorbed water vapor leaves the surface of the zeolite molecular sieve, it has already left the cooling capacity to the sintered honeycomb body. The sintered honeycomb body is equivalent to the cooling function of the evaporator (surface cooler) of a refrigerator. The air that subsequently flows through is cooled by the cooled sintered honeycomb body.

[0045] In summary, the entire cooling process of this utility model is as follows: the sintered honeycomb absorbs water → air passes through to desorb the water from the sintered honeycomb → the desorbed water vapor cools the sintered honeycomb → the cooled sintered honeycomb undergoes a continuous process of subsequent air cooling.

[0046] The molecular sieve material and honeycomb paper material, which play a crucial role in refrigeration in this invention and traditional water curtain air conditioners, have significantly different structural characteristics. These differences include three key factors that greatly affect the water vaporization rate:

[0047] 1. Water absorption rate (water absorption per unit volume of heat exchange material): The water absorption rate depends on the porosity of the material. The higher the porosity, the higher the water absorption rate. Without a good water absorption rate, the material cannot store enough water, thus failing to provide sufficient water supply for subsequent water vaporization. In terms of water absorption rate, both molecular sieve materials and honeycomb paper materials have a porosity of around 50%, so the difference in their water absorption rates is not significant.

[0048] 2. Permeability: The water permeation rate depends on the density of capillaries formed by the pores in the material. The function of capillaries is twofold: firstly, to allow the sprayed water that comes into contact with the local surface to penetrate inward and to the surrounding area until the material is fully saturated; secondly, to diffuse deep water to the surface. The finer and denser the capillaries, the higher the rate of water diffusion inward and outward. If the rate of water diffusion outward is low, even heat exchange materials that are saturated with water will experience a "surface dryness" phenomenon, and the heat exchange function will be lost. In this respect, the nanoscale pore structure of molecular sieve materials is far superior to that of honeycomb paper materials.

[0049] 3. Evaporation area: This is equivalent to the contact area between water and air. The larger the evaporation area, the higher the evaporation rate. Molecular sieve materials have an unparalleled specific surface area, several orders of magnitude higher than that of honeycomb paper materials; the two are not even in the same league.

[0050] Molecular sieve materials exhibit excellent performance in all three aspects mentioned above, while honeycomb paper materials lag far behind in the two key indicators of permeability and evaporation area.

[0051] Because the structure and performance of molecular sieve materials far exceed those of honeycomb paper materials, this invention can evaporate more water and obtain more latent heat of vaporization heat exchange capacity under the same air inlet temperature and air volume compared to water curtain air conditioners. This is the main factor that makes the cooling efficiency and outlet air temperature of this invention far superior to those of water curtain air conditioners. Therefore, this invention is smaller in size under the same cooling capacity.

[0052] The inclined guide plate installed inside the shell of this utility model is designed to prevent the fan's air force from acting on the lower part of the vertical air duct, which would cause the air volume entering the sintered honeycomb body from the horizontal direction to be uneven. The V-shaped air duct, which is wider at the top and narrower at the bottom, can ensure that the airflow from the sintered honeycomb body is relatively uniform from top to bottom.

[0053] In this utility model, the air inlet can be equipped with a filter screen to filter incoming dust, and the air outlet is equipped with louvers. The louvers can be set horizontally or horizontally and vertically, and the angle of the louvers can be adjusted manually or electrically.

[0054] This utility model can be equipped with air inlets in different directions, such as top, front, side and rear. One or two air inlets can be selected for air intake. Outdoor fresh air can be introduced through air inlets on the top, back or side of the air conditioner. Alternatively, the air inlets on the front or side can be opened into the room to obtain various effects such as 100% fresh air, fresh air + internal circulation air or all internal circulation air.

[0055] The water injection method of this utility model includes a water injection pipe 4 that can be connected to a tap water pipe and a flip-top manual water injection port 5. The former is suitable for use in a fixed position, while the latter is suitable for use when moving.

[0056] Example 2: As Figure 3 and Figure 4As shown, an energy-saving air conditioner includes a housing 1, an air inlet 2, a sintered honeycomb structure 7, a sprayer 10, a water pump 9, and an air outlet 3. The air inlet 2 is located at the upper part of the housing 1, and the air outlet 3 is located on the front of the housing 1.

The sintered honeycomb structure 7 is a molecular sieve honeycomb block with good water absorption. The sprayer 10 is located on the windward side of the sintered honeycomb structure 7.

[0064] In this example, the air outlet 3 of the housing 1 is provided with louvers 31, which are installed on the housing 1.

[0065] Example 2 is applicable to large-scale models. The fan is located on the outside, so a high-power fan can be used. On the one hand, it does not occupy the limited space inside the casing, and on the other hand, it isolates the strong noise of the high-power fan.
