[0031] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clear, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.

[0032] The principles and structures of the present application will be described in detail below in combination with the drawings and examples.

[0033] The existing regeneration air of the rotary dehumidifier is sucked from the regeneration air inlet by the action of the regeneration air fan, heated to a very high temperature after being heated by electricity, enters the treatment area of the rotary wheel, dehumidifies the rotary wheel, and finally is discharged to the outdoor from the regeneration air outlet. The direct heating of the regeneration air by electricity causes waste of electric energy source. In addition, the existing rotary dehumidifier sucks the room to be dehumidified from the treatment air inlet by the action of the treatment air fan, passes through the treatment area of the rotary dehumidifier, and has a relatively high temperature, which can cause a large increase in the indoor temperature.

[0034] As shown in Figure 1 , for this, the present application provides a duct structure for a rotary dehumidification air conditioner. The rotary dehumidification air conditioner mainly comprises: a compressor 1, an oil separator 2, a gas-liquid separator 3, a condenser 4, an evaporator 5, a throttling valve, a rotary dehumidifier 8 and other components (the specific connection is not the focus of the present application and will not be described in detail), wherein the rotary dehumidifier 8 has a regeneration air area, and the condenser 4 is a air-cooled condenser. The duct structure specifically comprises: a recovery air duct 6 communicating the condenser air outlet side with the regeneration air area of the rotary dehumidifier, an exhaust air duct 7 communicating the middle part of the recovery air duct with the outside, and a recovery air valve 61 provided at the end of the recovery air duct, and an exhaust air valve 71 provided at the exhaust air duct.

[0035] That is, by providing the recovery air duct, the heat generated by the air conditioner condenser can be used to supply hot air to the regeneration air area of the rotary dehumidifier. At the same time, by providing the exhaust air duct, the excess heat can be discharged to avoid the influence of the high indoor temperature on the overall working condition.

[0036] Specifically, a temperature sensor is provided at the inlet of the recovery air duct (i.e. communicating the condenser air outlet side), which is used to detect the air outlet temperature t 出 of the condenser air outlet side, a wind speed sensor is provided at the end of the recovery air duct to detect the wind speed, which is used to obtain the air volume w 收 , and a temperature sensor is provided at the end of the recovery air duct, which is used to detect the return air temperature t 回 of the end of the recovery air duct.

[0037] The application further provides a rotary dehumidification air conditioner, in particular a direct expansion rotary dehumidification air conditioner system, comprising the air duct structure.

[0038] The rotary dehumidification air conditioner adopts the air duct structure, which can effectively utilize the heat generated by the condenser and reasonably distribute the heat to avoid excessive heat affecting the overall working condition and maximize the energy consumption efficiency.

[0039] The design of the separation and recovery air duct and the exhaust air duct enables the system to flexibly control the direction of heat energy. In some working conditions, a part of hot air is appropriately discharged through the exhaust air duct to prevent excessive heat from flowing back to the system and avoid overheating of the system, while in other conditions, as much hot air as possible is recovered to improve the energy recovery efficiency.

[0040] As shown in Figure 2 , the application further provides a control method for a rotary dehumidification air conditioner, which uses the rotary dehumidification air conditioner and specifically comprises the following steps:

[0041] obtaining a set regeneration air power P 总 of the rotary dehumidifier, which corresponds to the actual dehumidification working condition requirement of the rotary dehumidifier;

[0042] calculating a total condenser hot air power P 热 generated by the condenser in the recovery air duct;

[0043] controlling the opening state of each air valve according to the comparison relationship or numerical size between the regeneration air power P 总 and the total condenser hot air power P 热 .

[0044] The set regeneration air power P 总 is always set based on the actual dehumidification working condition requirement of the air conditioning equipment and is directly related to the dehumidification efficiency and energy consumption level of the rotary dehumidifier. The more accurately the regeneration air power matches the working condition requirement, the better the effective operation of the equipment under different environmental conditions can be ensured, thereby improving the overall dehumidification effect and energy utilization efficiency. According to the comparison relationship between the regeneration air power and the condenser hot air power or the numerical size of the two, the opening state of each air valve is controlled to ensure that the system achieves the best dehumidification and temperature control effect under different working conditions. By dynamically adjusting the air valve opening degree, the system can adapt to the changing load demand during operation, thereby improving the flexibility and energy saving level of the overall operation.

[0045] As shown in Figure 3 , in a specific embodiment, after calculating the total condenser hot air power P 热 generated by the condenser in the recovery air duct, the hot air recovery power P 收 at the end of the recovery air duct is further calculated.It can accurately assess the portion of hot air actually recovered after passing through the recovery duct, in order to optimize the system's energy utilization.

[0046] The recovery duct is connected to the exhaust duct. When the exhaust duct is open, some hot air is discharged from the system through the exhaust duct, rather than being entirely captured by the recovery duct. Therefore, the hot air recovery power P at the end of the recovery duct needs to be calculated. 收 This can help clarify exactly how much heat energy is effectively recovered and how much heat energy is emitted from the system.

[0047] The total power P of the hot air generated by the condenser 热 This represents the system's potential heat output during the condensation process. However, due to the opening of the exhaust duct causing some hot air to be directly discharged, the final usable heat energy of the system will be lower than P. 热 Therefore, P 收 This reflects the actual heat energy recovered, which is equal to Pheat minus the power of the hot air discharged through the exhaust duct. The power Pheat recovered from the hot air at the end of the recovery duct is calculated. 收 By performing calculations, the system can more accurately understand the efficiency of thermal energy utilization, and also identify energy losses in the exhaust duct during the exhaust process. This refined energy allocation and management helps improve the operating efficiency of the air conditioning system, reduce energy consumption, and thus achieve greater energy-saving effects.

[0048] In a specific embodiment, based on the regenerated wind power P 总 Total power of condenser hot air P The comparison relationship between heat sources controls the opening status of each air valve, specifically including the following operating steps:

[0049] When the total power of the condenser hot air P 热 Greater than the regenerated wind power P 总 At the same time, the system will open the air valves of the exhaust duct and the recovery duct simultaneously. By adjusting the opening of the air valves, the hot air is rationally distributed to ensure that the amount of hot air recovered meets the regeneration requirements, while excess hot air is effectively discharged through the exhaust duct to avoid heat overload in the system.

[0050] The system will be based on the total hot air power P of the condenser. 热 With regenerated wind power P 总 The opening of the exhaust duct damper is adjusted based on the difference in airflow. Specifically, by finely adjusting the opening of the exhaust duct damper, the power P of the hot air recovered through the recovery duct is adjusted. 收 Equal to the set regenerated air power P 总 When there is an oversupply of hot air, the opening of the exhaust duct damper will gradually increase to expel the excess heat, while the recovery duct will only capture the portion of heat that matches the regeneration conditions to achieve system balance.

[0051] This control method allows the system to effectively regulate airflow and achieve precise management of thermal energy. Under certain operating conditions, the condenser may generate excessive hot air. If this hot air is completely diverted into the recovery duct, it can lead to system overheating, energy waste, or operational instability. Therefore, opening the exhaust duct and adjusting its damper opening can release excess heat, preventing system malfunctions due to excess heat. Simultaneously, ensuring that the hot air recovery power Precovered equals the regeneration air power Ptotal also helps prevent excessive regeneration air energy consumption due to excess energy, thereby optimizing the overall energy efficiency of the equipment.

[0052] When the total power of the condenser hot air P 热 Greater than the regenerated wind power P 总 When necessary, the air valves of the exhaust and regeneration ducts are opened, and the opening degree of the exhaust duct valve is precisely adjusted to ensure that the power of the recovered hot air matches the demand for regeneration air. This dynamic adjustment method not only ensures the safe operation of the equipment but also maximizes energy efficiency, ensuring that the system can operate stably and efficiently under different operating conditions.

[0053] In a specific embodiment, based on the regenerated wind power P 总 Total power P of condenser hot air 热 The comparison relationship between them is used to control the opening status of each air valve, specifically including the following situations:

[0054] When the total power of the condenser hot air P 热 Less than or equal to the regenerated wind power P 总 When this happens, the system will close the exhaust duct valve and keep or open the recirculation duct valve.

[0055] Then calculate the set regenerated air power P 总 With hot air recovery power P 收 The difference P 差 Difference P 差 As the power source for the rotary dehumidifier.

[0056] In this case, the system aims to maximize the recovery of heat energy generated by the condenser to meet the power requirements of the regeneration air, thereby ensuring efficient operation of the equipment. The total power P of the hot air generated by the condenser... 热 It is no longer sufficient to fully meet the regenerated wind power P 总 The system will no longer exhaust heat through the exhaust duct, but will instead recover all hot air through the recovery duct. Therefore, closing the exhaust duct valve ensures maximum heat recovery, avoids heat waste, and ensures that as much heat as possible is obtained during the regeneration process, thereby improving energy utilization efficiency.

[0057] The difference Pdiff between the set regenerative air power Ptotal and the recovered hot air recovery power Prec at the end of the recovery air duct is calculated. This difference Pdiff reflects the gap between the current recovered heat energy and the regenerative air demand, directly determining the additional energy needed to provide the rotary dehumidifier.

[0058] Difference P 差 As the power supply for the rotary dehumidifier, the system will dynamically adjust the energy supply to the rotary dehumidifier according to the difference. This energy supply form can be realized through electric heating energy supply mode, ensuring that the dehumidification efficiency in the regeneration process is not affected. In the case of harsh working conditions or insufficient condenser hot air supply, the calculation of P 差 can provide reliable basis for system adjustment, ensuring that the power of regenerative air always matches the actual needs to maintain stable dehumidification effect.

[0059] This control strategy not only maximizes the recovery of condenser heat energy, but also flexibly responds to the situation of insufficient hot air, ensuring that the system meets the regenerative air demand under the premise of low energy consumption. This difference control method not only improves energy utilization efficiency, but also enhances the adaptability of the system to different working conditions, thereby avoiding the decline of system operation efficiency due to insufficient heat supply.

[0060] In specific embodiments, according to the numerical size between the regenerative air power P 总 and the total condenser hot air power P 热 , the opening state of each air valve is controlled, which also includes the following cases: when the system does not use the rotary dehumidifier, the set regenerative air power P 总 is 0, at this time the demand for regenerative air does not exist, so the system does not need regenerative air to provide any energy. In this case, the system will automatically open the air valve of the exhaust air duct and close the air valve of the recovery air duct.

[0061] The excess hot air or other exhaust gas generated by the condenser is directly discharged from the system through the exhaust air duct, avoiding unnecessary heat recovery to the air conditioner interior. Because in the working condition without regenerative air demand, the recovery of heat energy not only has no practical significance, but also may cause heat accumulation in the system, affecting the temperature control effect of the air conditioning body. Therefore, closing the air valve of the recovery air duct can ensure that the hot air is not recovered, but directly discharged to the outdoor or other designated location through the exhaust air duct.

[0062] Opening the air valve of the exhaust air duct also plays the role of "heat dissipation channel" of the system at this time, which can effectively discharge the excess heat or exhaust gas generated during the operation of the air conditioning system, preventing overheating of the equipment or heat retention. This design not only helps to protect the stability of the system, but also improves the safety and operation efficiency of the equipment. Closing the air valve of the recovery air duct can also reduce the complexity of energy flow within the system, avoiding the increase of energy consumption caused by unnecessary air flow interference.

[0063] Specifically, calculate the total power P of the condensing hot air generated by the condenser. 热 Specifically, it includes:

[0064] Detect the speed of the air-cooled fan corresponding to the condenser, and obtain the airflow (w) of the air-cooled fan. 冷 And to detect the outlet air temperature t of the air-cooled fan. 出 By air volume w 冷 and outlet air temperature t 出 Calculate the total power P of the condensing hot air 热 .

[0065] Combined with air volume w 冷 and outlet air temperature t 出 The system can calculate the total power P of the condensing hot air. 热 Specifically, the total power P of the condensing hot air 热 The calculation formula is usually based on thermodynamic principles and can be expressed as:

[0066]

[0067] in:

[0068] ρ is the air density (usually a constant value, with appropriate corrections based on temperature and pressure);

[0069] c p This is the specific heat capacity of air (usually a constant, approximately 1.005 kJ / kg·°C).

[0070] w 冷 The air volume of the air-cooled fan is the mass flow rate of air passing through the condenser per unit time.

[0071] ΔT is the temperature difference, i.e., the outlet air temperature t of the air-cooled fan. 出 The difference between the temperature and the room temperature.

[0072] Total power of condensing hot air P 热 With air volume w 冷 Proportional to the temperature difference, by accurately measuring these two parameters, the total hot air power generated by the condenser under a given operating condition can be calculated precisely.

[0073] Using this method, the system can calculate and adjust the hot air power P generated by the condenser in real time. 热 This ensures that the system always operates under efficient thermal management conditions.

[0074] Specifically, calculate the heat recovery power P at the end of the recovery duct. 收 Specifically, it includes:

[0075] The wind speed is detected by a wind speed sensor at the end of the duct, and the air volume w is obtained.收 and detecting the return air temperature t at the end of the recovery air duct 回 , the air volume w 冷 and the return air temperature t 回 are calculated. 热 .

[0076] After obtaining the air volume w 收 and the return air temperature t 回 , the system can calculate the heat recovery power P 收 at the end of the recovery air duct by formula. The formula is similar to that for calculating the total condenser heat recovery power, and generally takes the following form:

[0077]

[0078] Wherein:

[0079] ρ is the air density, which is usually a constant;

[0080] cp is the specific heat capacity of air, which is usually a constant, about 1.005 kJ / kg·°C;

[0081] w 收 is the air volume passing through the recovery air duct, i.e. the air mass flow rate in the recovery air duct;

[0082] ΔT 收 is the temperature difference, which is the difference between the return air temperature t 回 at the end of the recovery air duct and the regeneration air temperature.

[0083] The method of directly obtaining the air volume and the temperature difference is simpler and does not require too many detection elements, so that the heat recovery power P 收 can be calculated in real time and adjusted after the air valve, ensuring that the system always operates in an efficient working condition.

[0084] In summary, the control method realizes the optimal allocation of the recovery air flow of the air conditioning system by accurately controlling the regeneration air power and the condenser heat recovery power. Not only can the system operating state be adjusted according to the actual working condition to improve the dehumidification efficiency, but also the system energy consumption can be reduced through energy recovery and air valve control, ensuring that the equipment is always in an efficient and energy-saving working state.
