[0002] In the current market, common fresh air dehumidifiers are mainly used to treat indoor air, improving air quality by dehumidifying and temperature regulating. However, traditional fresh air dehumidifiers have some significant defects in practical applications. Especially when dealing with the process requirements of complex and special occasions, their performance and efficiency often fail to meet the requirements. The working principle of traditional fresh air dehumidifiers mainly relies on the refrigeration system. The refrigeration system cools the air below the dew point temperature for dehumidification, and then heats the air to achieve the required outlet air temperature and humidity. In summer, when the inlet air temperature is high, in order to cool the air to the required dew point temperature, the dehumidifier needs to consume a large amount of energy. This not only leads to a significant increase in the energy consumption of the dehumidifier, but also significantly increases the manufacturing and operating costs of the equipment. In addition, traditional dehumidifiers have poor flexibility in temperature and humidity regulation and are difficult to precisely meet the requirements of different processes for air treatment.

[0003] In view of this, research and improvement are carried out on the existing problems, and a PVT-assisted energy-saving fresh air air treatment equipment is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.

It should be noted that, without conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0017] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of this utility model.

[0018] The following describes a PVT-assisted energy-saving fresh air handling device provided by some embodiments of this utility model with reference to the drawings.

[0019] Combined with Figure 1 As shown, a PVT-assisted energy-saving fresh air handling device provided by this utility model includes: an energy storage cabinet, a refrigeration system, a air supply system, a PV / T solar photovoltaic panel, a heating system, an electric control system, a plate heat exchanger, a hot water storage tank and a heat pump system;

[0021] The air supply system includes a main air supply fan and an air volume control valve component for adjusting and conveying the processed air;

[0022] The PV / T solar photovoltaic panel integrates power generation and heat collection functions. The generated electric energy is used for the operation of the equipment, and the collected solar heat is used for the heating system;

[0023] A heating system, comprising a heat pump heating device, a PV / T solar heating and heat dissipation device, as well as a rear hot water coil and a regenerative hot water coil, for extracting thermal energy from a hot water storage tank through a heat pump to heat air when needed;

[0024] A heat pump system, connected to a refrigeration system through a plate heat exchanger, recovering waste heat during the refrigeration process and storing it in a hot water storage tank;

[0025] An electric control system, realizing intelligent control of the entire device through a human-machine interface, automatically adjusting the operating states of each component to ensure high efficiency and energy conservation;

[0026] A hot water storage tank, for storing the thermal energy generated by the heat pump system and the PV / T device, providing a heat source for the heating system;

[0027] A regeneration fan, for regenerating the moisture absorption wheel in the dehumidification system to ensure the dehumidification effect;

[0028] An overall framework, with each component tightly connected therein, improving energy efficiency and energy conservation effect.

[0029] In this embodiment, the heat pump system further includes an optimized control strategy to improve the waste heat recovery efficiency and the thermal energy storage efficiency of the hot water storage tank.

[0030] Specifically, the optimized control strategy can more precisely control the operating parameters of the heat pump system, such as the flow rate and temperature of the working medium, so as to more effectively recover the waste heat generated in the refrigeration system or other technological processes. This efficient recovery not only reduces energy waste but also improves the overall energy utilization efficiency of the system. By optimizing the thermal energy storage process of the hot water storage tank, such as using more efficient thermal insulation materials and optimizing the structural design of the tank, the loss of thermal energy during storage can be reduced, ensuring that the stored thermal energy can maintain a high temperature state for a longer time for subsequent use.

[0031] In this embodiment, the PV / T solar panel uses high-efficiency materials to improve the conversion efficiency of electric energy and thermal energy.

[0032] Specifically, the PV / T solar panel uses photovoltaic materials with high conversion efficiency, such as high-efficiency monocrystalline silicon, polycrystalline silicon, thin-film solar cells, etc. These materials have higher photoelectric conversion efficiency and can convert more solar energy into electric energy. On the back or integrated structure of the PV / T solar panel, materials with high thermal conductivity are used as the heat collection plate or heat pipe to effectively collect and conduct the heat generated by the photovoltaic cells. After using high-efficiency materials, the PV / T solar panel can simultaneously convert solar energy into electric energy and thermal energy efficiently, realizing the comprehensive utilization of solar energy. Compared with a single photovoltaic system or solar thermal system, the PV / T system has higher energy utilization efficiency.

[0033] In this embodiment, the air supply system further includes an air filtration device for purifying the treated air.

[0034] Specifically, it improves air quality: The air filtration device can effectively remove harmful substances such as dust, bacteria, and viruses in the air, improving the cleanliness and quality of indoor air. It reduces impurities and particulate matter in the air entering the equipment, lowering the failure rate and maintenance cost of the equipment caused by dust accumulation. At the same time, it is of great significance for ensuring personnel health, improving production efficiency, and product quality.

[0035] In this embodiment, the electric control system has remote monitoring and fault diagnosis functions, and can monitor the equipment status in real time and provide solutions.

[0036] Specifically, the electric control system establishes a connection with a remote server through a built-in communication module (such as 4G / 5G, Wi-Fi, LoRa, etc.) to transmit the operation status data of the equipment in real time. These data include but are not limited to key parameters such as temperature, pressure, current, and voltage. The cloud platform uses intelligent algorithms to process and analyze the received data to identify possible faults or abnormal states of the equipment. These algorithms may include advanced technologies such as machine learning and deep learning, which can accurately judge the type and location of faults. The remote monitoring and fault diagnosis functions enable maintenance personnel to understand the operation status and fault conditions of the equipment without having to be on-site, greatly saving time and labor costs. At the same time, the quick response and timely handling of faults also improve the reliability and stability of the equipment.

[0037] In this embodiment, the hot water storage tank is provided with a heat insulation layer to reduce heat energy loss.

[0038] In this embodiment, the air supply system further includes a dehumidification system that works in cooperation with the regeneration fan and the moisture absorption rotor to achieve air dehumidification. The dehumidification system includes a humidity sensor for automatically adjusting the dehumidification state.

[0039] Specifically, the moisture absorption rotor is the core component of the dehumidification system and is usually made of materials with strong hygroscopicity, such as silica gel and lithium chloride. The rotor is divided into a moisture absorption area and a regeneration area, and continuously alternates the moisture absorption and regeneration processes through rotation. The regeneration fan is responsible for supplying high-temperature or low-humidity air to the regeneration area to remove the moisture adsorbed on the moisture absorption rotor and restore the moisture absorption capacity of the rotor. The dehumidification system effectively removes excess moisture in the air, reduces indoor humidity, prevents mold growth and odor generation, and improves the freshness and comfort of indoor air.

[0040] The working principle and usage process of the present utility model:

[0041] Initial settings: Through the man-machine interface, parameters such as the working mode, temperature, and humidity of the device are set, and the electric control system adjusts the initial working states of each component according to the set values. The electric control system monitors the working states of each component in real time through the man-machine interface and internal sensors, and automatically adjusts the operating parameters of each component to ensure the efficient and energy-saving operation of the device.

[0042] Power generation and heat collection: The PV / T solar photovoltaic panel starts to work, integrating power generation and heat collection functions simultaneously. The generated electric energy is directly supplied to the operation of the device, such as compressors, main supply fans, and regeneration fans; the collected solar heat is transported through pipelines to the heating system.

[0043] Refrigeration cycle: The compressor starts, inhaling low-temperature and low-pressure refrigerant gas, which becomes high-temperature and high-pressure gas after compression and enters the condenser to release heat and condense into a liquid. The condensed refrigerant passes through a throttling device to reduce pressure and temperature, enters the evaporator to absorb heat and evaporate, forming low-temperature and low-pressure steam, which is then inhaled by the compressor to complete the refrigeration cycle.

[0044] Waste heat recovery: The heat pump system is connected to the refrigeration system through a plate heat exchanger to recover the waste heat discharged from the evaporator. After being processed by the heat pump, the heat energy is stored in the hot water storage tank.

[0045] Heat pump heating: When air needs to be heated, the heat pump heating device extracts heat energy from the hot water storage tank and transfers the heat to the post-hot water coil through the heat pump cycle to heat the passing air.

[0046] PV / T solar auxiliary heating: If the heat energy in the hot water storage tank is insufficient or additional heating is required, the PV / T solar heating and heat dissipation device will directly use solar heat for supplementary heating.

[0047] Air treatment: The air that has undergone refrigeration or heating treatment is sent into the room through the main supply fan of the air supply system. The air volume control valve automatically adjusts the air supply volume according to the indoor demand.

[0048] Air purification: The air filtration device in the air supply system purifies the treated air, removing harmful substances such as dust and bacteria to ensure the air quality sent into the room.

[0049] Humidity detection: The humidity sensor in the dehumidification system monitors the indoor humidity in real time. When the humidity exceeds the set value, the dehumidification mode is automatically started.

[0050] Dehumidification cycle: The regeneration fan starts to regenerate the moisture absorption wheel in the dehumidification system, discharging the adsorbed moisture. At the same time, the moisture absorption wheel adsorbs the moisture in the air during rotation to achieve air dehumidification.
