Description

Technical Field

[0001] The invention relates to the technical field of dehumidification, and in particular to a high-efficiency dehumidification system. Background Art

[0002] At present, the dehumidifiers on the market are mainly divided into household type, industrial type and other professional type. However, no matter which type of dehumidifier, the market share of the refrigeration principle type dehumidifier is absolutely large. The key components of the refrigeration principle type dehumidifier are two devices, namely the evaporator and the condenser. However, the two devices of the refrigeration type dehumidifiers on the market now have poor operating effects in low temperature environments, because the humid gas in the low temperature environment will frost more seriously on the surface of the evaporator. The thick frost layer will affect the air volume and heat exchange efficiency of the gas, and the compressor needs to be frequently shut down for defrosting, which seriously affects the dehumidification efficiency and has high energy consumption. In addition, the defrosting of conventional dehumidifiers is natural defrosting, which makes it difficult to melt the frost on the evaporator and fails to achieve the purpose of rapid dehumidification.

[0003] The natural defrosting process of the evaporator with a single temperature will suspend the overall dehumidification process, resulting in poor dehumidification effect. If a defrosting mechanism is added, the cost and energy consumption will increase.

[0004] The existing patent document with patent application number CN202111131435.6 discloses a dehumidification system, including: a first heat exchanger, a surface of which is provided with a water-absorbing material; a second heat exchanger, a surface of which is provided with a water-absorbing material, and one of the first heat exchanger and the second heat exchanger selectively acts with a cold source to reduce the temperature of the first heat exchanger or the second heat exchanger; a first air duct, and the first heat exchanger is located in the first air duct; a second air duct, and the second heat exchanger is located in the second air duct, and the air inlet of one of the first air duct and the second air duct is connected to the external hot air source, and the air inlet of the other is connected to the outside air, and the first heat exchanger or the second heat exchanger in the other one acts with the cold source.

[0005] Although the above structure also uses two heat exchangers, which are equivalent to evaporators, they are arranged in parallel, that is, they are arranged in the inlet and outlet pipes respectively and operate independently. The dehumidification effect is increased by doubling the investment in material costs. Moreover, the newly added equipment has the same power and doubles the energy consumption, but the heat exchange efficiency is low, and the medium injection volume is large, and the overall cost is high.

[0006] In order to improve dehumidification efficiency, maintain uninterrupted dehumidification function, reduce overall equipment cost, reduce overall energy consumption, and improve the energy saving of the system, the present invention designs a new high-efficiency dehumidification system, which is described and implemented through the following technical scheme.

DETAILED DESCRIPTION

[0034] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0035] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0036] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] The objects of the present invention are:

[0038] Improve the performance of the dehumidification system. By optimizing the layout of the evaporator and condenser, the heat exchange efficiency can be improved while reducing energy consumption, thereby improving the overall performance of the dehumidification system;

[0039] Reduce equipment costs by researching and developing new high-efficiency dehumidifiers, and reduce usage costs while maintaining dehumidification quality and heat exchange efficiency.

[0040] Specific embodiments, the specific implementation methods of the present invention are as follows: Figures 1 to 6 As shown, the present invention provides a high-efficiency dehumidification system.

[0041] like Figure 1-2 As shown, in embodiment 1 of the present invention, which is the most basic real-time method of the present invention, a high-efficiency dehumidification system includes: a compressor 1, a condenser assembly 2, an evaporator assembly 3 and a dehumidification pipeline 4, the compressor 1 includes a compressor outlet end 11 and a compressor air collecting end 12, the compressor outlet end 11 is connected to the condenser assembly 2, and the compressor air collecting end 12 is connected to the evaporator assembly 3;

[0042] The dehumidification pipeline 4 includes an air inlet end 41 and an air outlet end 42, the evaporator assembly 3 is arranged in a tube near the air inlet end 41 in the dehumidification pipeline 4, the condenser assembly 2 is arranged in a tube near the air outlet end 42 in the dehumidification pipeline 4, and a throttling device 5 is arranged between the evaporator assembly 3 and the condenser assembly 2;

[0043] The evaporator assembly 3 includes at least two evaporator devices, each of which is arranged in sequence in the dehumidification pipe 4, and the temperature of each evaporator device decreases gradually. The condenser assembly 2 includes at least two condenser devices, each of which is arranged in sequence in the dehumidification pipe 4, and the temperature of each condenser device increases gradually.

[0044] like Figure 2As shown, the condenser assembly 2 includes a high-temperature condenser 21 and a low-temperature condenser 22, and the condensation temperature of the high-temperature condenser 21 is higher than the condensation temperature of the low-temperature condenser 22;

[0045] The evaporator assembly 3 includes a high-temperature evaporator 31 and a low-temperature evaporator 32, wherein the evaporation temperature of the high-temperature evaporator 31 is higher than the evaporation temperature of the low-temperature evaporator 32;

[0046] In the dehumidification duct 4 , air passes through the high-temperature evaporator 31 , the low-temperature evaporator 32 , the low-temperature condenser 22 , and the high-temperature condenser 21 in sequence.

[0047] The principle of the present invention is: similar to the function of a heat pipe, but the heat pipe is an independent system and has nothing to do with the refrigerant in the compressor refrigeration system. The present invention uses multiple changes in the flow state of the refrigerant in the compressor refrigeration system to achieve the heat pipe function; the liquid refrigerant coming out of the high-temperature condenser 21 becomes a gas-liquid mixed state after passing through the throttling device 5, enters the high-temperature evaporator 31 (equivalent to the front-end heat exchanger of the heat pipe), absorbs heat and evaporates into a gaseous state in the high-temperature evaporator 31, thereby achieving the cooling and dehumidification of the inlet air in the dehumidification pipe 4; after the vaporized refrigerant comes out of the high-temperature evaporator 31, it enters the low-temperature condenser 22 (equivalent to the rear-end heat exchanger of the heat pipe) for condensation, and the refrigerant changes from a gaseous state to a liquid state. The reason why it can be condensed is that the inhaled air is cooled by the low-temperature evaporator and the temperature is lower than that of the low-temperature condenser, so the refrigerant in the low-temperature condenser will be condensed into a liquid state, and then throttled again by the throttling device 5, enters the low-temperature evaporator to absorb heat and evaporate, and finally returns to the compressor gas collecting end 12. What comes out of the low-temperature evaporator is a gaseous state, which prevents the compressor from liquid compression.

[0048] The existing dehumidification system only has a low-temperature evaporator and a high-temperature condenser, but not a high-temperature evaporator and a low-temperature condenser. The present invention now adds a high-temperature evaporator and a low-temperature condenser. During the dehumidification cycle, the refrigerant medium is allowed to circulate again, which adds one more treatment of the air, utilizes the waste heat, and improves the dehumidification capacity, which is equivalent to adding an additional dehumidification system.

[0049] The system of the present invention is more effective than a heat pipe, which flows naturally through phase changes. Some designs will add additional power devices to increase the flow rate of the medium in the heat pipe, but on the other hand, it also increases energy consumption, and at present, this type of power pump is easy to break, which also increases procurement and maintenance costs.

[0050] The present invention realizes multiple evaporation temperatures by arranging multiple evaporators. The wind passes through the high-temperature evaporator in sequence, so that the high-temperature and high-humidity initial intake air is first cooled and its humidity is increased to become low-temperature humidity saturated air. After passing through the low-temperature evaporator, the low-temperature humidity saturated air is further cooled and directly and quickly condensed and liquefied into water. The evaporation temperature of the low-temperature evaporator is higher than the evaporation temperature of a conventional single evaporator.

[0051] The gradually lowering temperature evaporator method adopted in the present invention not only improves the overall dehumidification effect, but also avoids the need for a lower cooling medium temperature when using a single evaporator. The evaporation temperature of the low-temperature evaporator 32 is slightly higher than that of the traditional single evaporator, which avoids the situation where the temperature is too low when water vapor condenses, forming an ice layer covering the surface of the evaporator, and requiring shutdown for natural temperature rise for defrosting, which pauses the dehumidification process and greatly reduces the dehumidification effect. At the same time, the evaporation temperature increases, which reduces the power consumption of the refrigeration system and makes the refrigeration system energy-efficient.

[0052] Multiple condenser devices are used at the same time to achieve multi-stage condensation and reduce the maximum temperature of the condenser; the condensation temperature is reduced, which reduces the output power consumption of the overall compressor, making the overall more energy-efficient.

[0053] The specific connection method is as follows Figure 2 As shown, the high-temperature condenser 21 is provided with a high-temperature condenser air inlet pipe 211 and a high-temperature condenser liquid outlet pipe 212, the high-temperature evaporator 31 is provided with a high-temperature evaporator liquid inlet pipe 311 and a high-temperature evaporator air outlet pipe 312, the low-temperature condenser 22 is provided with a low-temperature condenser air inlet pipe 221 and a low-temperature condenser liquid outlet pipe 222, and the low-temperature evaporator 32 is provided with a low-temperature evaporator liquid inlet pipe 321 and a low-temperature evaporator air outlet pipe 322.

[0054] The high-temperature condenser air inlet pipe 211 is connected to the compressor air outlet 11 , and the throttling device 5 includes a first throttling device 51 , which is located between the high-temperature condenser liquid outlet pipe 212 and the high-temperature evaporator liquid inlet pipe 311 .

[0055] The high-temperature evaporator air outlet pipe 312 is connected to the low-temperature condenser air inlet pipe 221 , the low-temperature condenser liquid outlet pipe 222 is connected to the low-temperature evaporator liquid inlet pipe 321 , and the low-temperature evaporator air outlet pipe 322 is connected to the compressor air collecting end 12 .

[0056] The present invention adopts a condenser method of gradually increasing the temperature. The low-temperature condenser condenses the gas from the high-temperature evaporator into liquid so that it has the ability to evaporate again after throttling, and is recycled again to heat the low-temperature air after the water is cooled and condensed by the low-temperature evaporator, perform heat exchange, and perform preliminary heating of the low-temperature air. The heat for this heating comes from the initial incoming air. The conventional dehumidification system directly recycles the cooling medium for cyclic heating, which wastes this part of the heat.

[0057] The present invention does not require the addition of a heating and defrosting device. The refrigerant that has initially absorbed heat and vaporized enters the condenser for circulation heating, thereby increasing the temperature of the air entering the high-temperature condenser, achieving a better effect of heating the air, reducing the total heating capacity of the compressor in the system, and further reducing the overall energy consumption. The present invention achieves energy-saving effects in both evaporation and condensation, while avoiding the risk of frost and reducing the time of downtime for defrosting.

[0058] Embodiment 2, as Figure 3 As shown, including all the technical features of Example 1, on the basis of Example 1, the throttling device 5 of the present invention also includes a second throttling device 52, and the second throttling device 52 is arranged between the low-temperature condenser liquid outlet pipe 222 and the low-temperature evaporator liquid inlet pipe 321.

[0059] In order to improve the dehumidification effect, a second throttling device 52 can be added. The second throttling device 52 is used for expansion refrigeration to reduce the surface temperature of the middle low-temperature evaporator 32, so that the low-temperature humidity saturated air can be quickly cooled and condensed and flowed out.

[0060] The first throttling device 51 and the second throttling device 52 are one of a capillary tube, a thermal expansion valve, an electronic expansion valve, an orifice plate throttling or any combination thereof. In the present invention, the first throttling device 51 and the second throttling device 52 are both electronic expansion valves.

[0061] Embodiment 3, as Figure 4 As shown: including all the technical features of Example 1, on the basis of Example 1, the condenser assembly 2 includes a high-temperature condenser 21 and a low-temperature condenser 22, and the condensation temperature of the high-temperature condenser 21 is higher than the condensation temperature of the low-temperature condenser 22.

[0062] In order to further lower the temperature of the high-temperature condenser 21 and reduce the energy consumption of the compressor 1, a condenser is added. The high-temperature and high-pressure cooling medium flowing out of the high-temperature condenser 21, whose temperature is still higher than the room temperature, can exchange heat with the air again. At the same time, it is arranged in front of the high-temperature condenser 21 to heat the air treated by the low-temperature evaporator 22, and utilize the remaining heat to improve the heat utilization efficiency and reduce the energy consumption of the compressor 1.

[0063] Specifically, the condenser assembly 2 also includes a medium-temperature condenser 23 , which is located between the high-temperature condenser 21 and the low-temperature condenser 22 , and the temperature of the medium-temperature condenser 23 is lower than the temperature of the high-temperature condenser 21 and higher than the temperature of the low-temperature condenser 22 .

[0064] The medium-temperature condenser 23 is provided with a medium-temperature condenser air inlet pipe 231 and a medium-temperature condenser liquid outlet pipe 232 . The medium-temperature condenser air inlet pipe 231 is connected to the high-temperature condenser liquid outlet pipe 212 , and the medium-temperature condenser liquid outlet pipe 232 is connected to the first throttling device 51 .

[0065] Embodiment 4, as Figure 5 As shown, all the technical features of Example 1 are included. On the basis of Example 1, a second throttling device 52 and a medium-temperature condenser 23 are additionally provided. Although the cost of the equipment is increased, the refrigeration and dehumidification effect is further enhanced, the dehumidification speed is accelerated, and the dehumidification effect is enhanced. At the same time, the medium-temperature condenser 23 is utilized to reduce the power consumption of the compressor 1, thereby achieving comprehensive optimization as a whole.

[0066] Embodiment 5, as Figure 6 As shown, including all the technical features of Example 1, on the basis of Example 1, the positions of the high-temperature evaporator 31, the low-temperature evaporator 32 and the low-temperature condenser 22 are optimized and arranged. Specifically, the high-temperature evaporator 31, the low-temperature evaporator 32 and the low-temperature condenser 22 are arranged in sequence in the dehumidification pipe 4 to form a heat exchanger structure.

[0067] This can increase the overall heat exchange efficiency and improve the dehumidification effect.

[0068] In summary, the present invention sets up a double evaporator, and the inhaled air passes through a design combining high evaporation temperature and low evaporation temperature in sequence, and then passes the air through multiple condensers in sequence, adopts a multi-condensation temperature design, and adopts a two-stage throttling cooling design. Through the above design, the energy saving of the system is highly improved; the inhaled air passes through high evaporation temperature and low evaporation temperature evaporators in sequence, and the high evaporation temperature evaporator processes the high-temperature and high-humidity initial intake air, and then the low-evaporation temperature evaporator processes the low-temperature and low-humidity saturated air treated with the high evaporation temperature. The saturated air improves the dehumidification capacity of the low evaporation temperature evaporator, and has greater latent heat and less sensible heat. The present invention eliminates the flash device, and the system is simpler. At the same time, a primary condenser is used to condense the gas after the primary evaporation, and then throttles through a throttling device.

[0069] The throttling loss of the system is greatly reduced, thereby reducing the system energy consumption.

[0070] The technical features of the above-mentioned embodiments can be combined arbitrarily, and the execution order of each method step is not limited. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
