Description

Technical Field

[0001] This invention belongs to the field of dryer technology, and relates to a heat pump rotor dehumidification system for a fast dryer, its application and design method. Background Technology

[0002] In recent years, with the continuous improvement of living standards, quick drying of clothes has become an indispensable requirement in hot and humid climates. Quick drying of clothes can improve washing and drying efficiency, increase the softness and fluffiness of garments, and prevent wrinkles; it can also effectively prevent mold and odor problems caused by the growth of fungi on the surface of clothing.

[0003] Currently, most dryers use hot air drying technology to remove moisture from clothes, including electric heating and more energy-efficient heat pump drying methods. This type of technology primarily utilizes high temperatures to evaporate moisture from clothes, but due to the humid air in hot and humid climates like those in southern regions, drying efficiency and energy efficiency are significantly reduced. In recent years, drying technology combining heat pumps and molecular sieve dehumidification rotors has emerged, building upon high-temperature drying. This technology uses the molecular sieve dehumidification rotor to dry the air during drying, thereby improving drying efficiency. Although this technology can accelerate the drying rate, it still has core technical shortcomings, mainly in the following aspects:

[0004] 1. Molecular sieves typically require regeneration temperatures above 100℃ to achieve effective regeneration, resulting in high energy consumption in drying systems;

[0005] 2. When molecular sieves are regenerated at lower temperatures, their dehumidification capacity is small, making it difficult to further improve the drying rate of clothes. Summary of the Invention

Furthermore, the optimized design achieves comprehensive utilization of the system's heat and cold energy, improving the system's operational energy efficiency.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] This invention proposes a heat pump dehumidification system for a fast clothes dryer, comprising a first air inlet A, a makeup air inlet E, a first evaporator 1, a polymer dehumidification rotor 2, a first condenser 3, a first compressor 4, a first expansion valve 5, a supply fan 6, a second air inlet B, a third air inlet C, a second condenser 7, a second evaporator 8, a regeneration fan 9, a second compressor 10, a second expansion valve 11, a fourth air inlet D, a supply air temperature sensor 12, a regeneration temperature sensor 13, a first air inlet valve 14, and a makeup air inlet valve 15.

[0062] The first air inlet A is connected in sequence to the first evaporator 1, the dehumidification zone of the polymer dehumidification rotor 2, the first condenser 3, the air supply fan 6, and the second air inlet B via a first air duct; the makeup air inlet E is connected in sequence to the first evaporator 1, the dehumidification zone of the polymer dehumidification rotor 2, the first condenser 3, the air supply fan 6, and the second air inlet B via a second air duct; the third air inlet C is connected in sequence to the second condenser 7, the second compressor 10, the regeneration zone of the polymer dehumidification rotor 2, the second evaporator 8, the regeneration fan 9, and the fourth air inlet D via a third air duct.

[0063] The first evaporator 1 is also connected in sequence to the first compressor 4, the first condenser 3 and the first expansion valve 5 through the first condenser pipe; the second evaporator 8 is also connected in sequence to the second compressor 10, the second condenser 7 and the second expansion valve 11 through the second condenser pipe.

[0064] The air supply temperature sensor 12 is installed on the first air duct between the first condenser 3 and the air supply fan 6; the regeneration temperature sensor 13 is installed on the third air duct between the second compressor 10 and the regeneration zone of the polymer dehumidification rotor 2.

[0065] A first air interface valve 14 is provided on the first air interface A; a makeup air interface valve 15 is provided on the makeup air interface E.

[0066] The first air interface A is connected to the dryer's exhaust port; the second air interface B is connected to the dryer's air inlet; the third air interface C, the fourth air interface D, and the make-up air interface E are directly connected to the environment.

[0067] In the heat pump dehumidifier dryer of this invention, the dehumidification zone of the polymer dehumidifier rotor 2 is located in the dryer's air supply duct. During system operation, the first compressor 4 and the second compressor 10 operate at full load, as do the air supply fan 6 and the regeneration fan 9. Specifically, the mixed air from the dryer's return air and make-up air is first cooled by the first evaporator 1 to improve the dehumidification capacity of the polymer dehumidifier rotor 2. The cooled air then enters the dehumidification zone of the polymer dehumidifier rotor 2 for dehumidification; the dehumidified air then enters the first condenser 3 and is heated to the clothes drying temperature, typically 60°C (up to 65°C), before being delivered to the dryer by the air supply fan 6 for clothes drying. Simultaneously, another heat pump system regenerates the dehumidifier rotor; the room air is heated to 50-65°C after passing through the second condenser 7 and the second compressor 10 (to prevent high temperatures from causing rotor failure) before entering the regeneration zone of the polymer dehumidifier rotor 2. After desorption, the air humidity is high, and it needs to be condensed by the second evaporator 8 before being discharged into the room.

[0068] By coupling the dual heat pump system with the polymer dehumidifying rotor of this invention, and with the matching design of the polymer dehumidifying rotor, heat pump evaporator, and condenser, the moisture content of the inlet air of the dryer can be as low as 3.06 g / kg under indoor air conditioning / heating conditions, and the drying temperature can reach as high as 65℃. Compared with the current new molecular sieve washer-dryer combo (drying time is about 45 min-1 h), it can achieve rapid drying of clothes in about 30 minutes.

[0069] This invention also provides a design method for the preparation of the heat pump rotor dehumidification system for the quick-drying machine, which is described below with specific steps and parameters. The design method specifically includes the following steps: Step 1: Determine the design conditions, including: the design value of the moisture content of the clothes G = 1.8 (kg), the outlet air temperature of the first evaporator 1 =14 (°C), air temperature at the outlet of the first condenser 3 =60 (°C), circulating air volume L=250 (m³) 3 / h), ambient air temperature =26 (°C), ambient air humidity =12.6 (g / kg);

[0070] Step 2: The dehumidification zone and regeneration zone areas of the polymer dehumidification rotor are in a 1:1 ratio. Based on the installation space, the polymer dehumidification rotor thickness is 200 mm, and the selected polymer dehumidification rotor diameter is 350 mm. The face velocity is approximately 1.5 m / s. Assume the outlet air temperature of the second condenser 7 is... =65 (°C);

[0071] Step 3: Assume drying time t = 0.5 (h); Step 4: Calculate the dehumidified air outlet temperature using polymer dehumidification rotor calculation software. =36.6 (°C), Moisture content =3.06 (g / kg) and regenerated air outlet temperature =42.2 (°C), Moisture content =19.4 (g / kg). The outlet air temperature and moisture content of the dryer were calculated using the formula mentioned above, which were 29.4℃ and 15.06 g / kg, respectively. Referring to the enthalpy-humidity chart of humid air, the relative humidity at this point was 58.01% < 70%, thus this calculation meets the requirements.

[0072] Step 5: Assume that the proportion of the air volume from the make-up air interface in the first air duct to the total air supply volume is f=0;

[0073] Step 6: Calculate the cooling capacity of the first evaporator 1 according to the formula proposed above. =2.44 (kW), the heating capacity of the first condenser 3 =1.97 (kW), determine the relationship between the cooling capacity of the first evaporator 1 and the heating capacity of the first condenser 3. - If the value is greater than 0.1, it is necessary to return to step 5 and increase the make-up air ratio. Ultimately, calculations show that a make-up air ratio of 0.6 is optimal. =1.95 (kW), =1.98 (kW)| - If |=0.03<0.1, proceed to the next calculation.

[0074] Step 7: Calculate the heating capacity of the second condenser 7 according to the formula mentioned above. =3.35 (kW), and based on the aforementioned formula, the saturated moisture content at the outlet of the second evaporator 8 is calculated as the cooling capacity of the second evaporator 8 is equal to the heating capacity of the second condenser 7. =13.1 (g / kg). Determine the relationship between the saturated moisture content at the outlet of the second evaporator 8 and the ambient moisture content, satisfying... - =0.5<1, then the overall calculation meets the requirements, and the design parameters of the polymer dehumidification rotor (thickness 200 mm, diameter 350 mm) are completed. The cooling capacity of the first evaporator 1 is 1.94 kW, the heating capacity of the first condenser 3 is 1.98 kW, the cooling capacity of the second evaporator 8 is 3.36 kW, and the heating capacity of the second condenser 7 is 3.36 kW.

[0075] The design challenges of the heat pump rotary dehumidification system for a quick-drying machine provided by this invention are: 1) To achieve rapid drying, the system has strict requirements on the temperature and heating capacity of refrigeration and heating, and the refrigeration and heating capacities need to be matched when utilizing the heat pump's refrigeration and heating functions; 2) The energy in each part of the system is strongly coupled. For example, a decrease in the temperature on the regeneration side of the polymer dehumidification rotary wheel not only affects the performance and design requirements of the second condenser and the second evaporator, but also affects the outlet air temperature and humidity of the polymer dehumidification rotary wheel, as well as the performance and requirements of the first evaporator and the first condenser. To address these design challenges, this invention uses trial calculations and cyclical calculations in steps 3-7 to match the refrigeration and heating capacities of the two heat pump systems, enabling the system to maximize comprehensive energy utilization while meeting the requirements for rapid drying.

[0076] The embodiments described above are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be conceived by those skilled in the art within the scope of the technology disclosed in this application without creative effort should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of protection of the claims in this application.
