Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] In modern building and industrial environments, humidity control is a crucial factor in ensuring comfort and proper equipment operation. Traditional dehumidifiers typically rely on a single cold source for humidity regulation, which results in problems such as low energy efficiency and unstable dehumidification performance.

[0020] In existing technologies, common dehumidification equipment often fails to achieve rapid and uniform dehumidification when dealing with large spaces or high humidity environments, leading to increased energy consumption and excessive equipment load. In addition, traditional equipment also has limitations in temperature control, making it difficult to maintain constant temperature and humidity under different climatic conditions, which affects the performance and user experience.

[0021] To address the aforementioned issues, this embodiment discloses a dual-cold-source deep constant-temperature dehumidification unit, the connection diagram of which is shown below. Figure 1 As shown, the unit includes an air supply module 101, a compressor 102, a condensing heat exchanger 103, an evaporating heat exchanger 104, and a regenerating heat exchanger 105. The liquid outlet of the compressor 102 is connected to the liquid inlet of the condensing heat exchanger 103, the liquid outlet of the condensing heat exchanger 103 is connected to the liquid inlet of the evaporating heat exchanger 104, the liquid outlet of the evaporating heat exchanger 104 is connected to the liquid inlet of the regenerating heat exchanger 105, and the liquid outlet of the regenerating heat exchanger 105 is connected to the liquid inlet of the compressor 102. The air supply module 101 is used to generate airflow that is blown into the evaporating heat exchanger 104 and blown out of the regenerating heat exchanger 105.

[0022] Furthermore, an oil separator 106 is also connected between the compressor 102 and the condenser heat exchanger 103.

[0023] Furthermore, a dual-tube liquid reservoir 107, a drying filter 108, a liquid pipe solenoid valve 109, an evaporation pressure control valve 110, and an electronic expansion valve 111 are sequentially connected between the condenser heat exchanger 103 and the evaporator heat exchanger 104.

[0024] Furthermore, the dual-cold-source deep constant-temperature dehumidification unit also includes a liquid-injection solenoid valve 112. One end of the liquid-injection solenoid valve 112 is connected between the dual-tube liquid reservoir 107 and the dryer filter 108, and the other end of the liquid-injection solenoid valve 112 is connected between the liquid outlet of the regenerating heat exchanger 105 and the liquid inlet of the compressor 102.

[0025] Furthermore, a gas-liquid separator 113 is also connected between the regenerative heat exchanger 105 and the compressor 102.

[0026] Furthermore, the air supply module 101 includes a centrifugal fan and an electric motor for driving the centrifugal fan to rotate.

[0027] In one embodiment, for operating conditions of 23±3℃ or 35±5℃, the following approach is provided: a dual-cooling-source method is adopted. The first stage uses chilled water for cooling, and the second stage uses direct expansion refrigeration for deep cooling to reach the dew point of the environmental conditions, thereby removing the moisture content in the air. Then, the condensation heat is used to raise the temperature and reduce the relative humidity value to meet the environmental requirements. The unit of this embodiment has the following characteristics:

[0028] 1. Two compressors (102) are installed in parallel, serving as backups for each other. Each compressor's exhaust port is equipped with a check valve; upon startup, one compressor opens while the other remains on standby. This balanced operation of the two compressors improves system reliability.

[0029] 2. Set upper and lower limits for exhaust temperature. When the temperature exceeds 70 degrees Celsius, open the liquid injection solenoid valve. When the temperature is below 65 degrees Celsius, close the liquid injection solenoid valve 112 to ensure that the exhaust temperature of compressor 102 is normal.

[0030] 3. The liquid line solenoid valve 109 and the compressor 102 open and stop simultaneously.

[0031] 4. The regenerative heat exchanger 105 works in conjunction with the axial flow fan to dissipate heat, and the start and stop of the axial flow fan are controlled by the return air temperature.

[0032] 5. Add air pressure pipes to both sides of the evaporator heat exchanger 104, and measure the air resistance drop of the evaporator heat exchanger 104 to adjust the frequency of the axial flow fan inverter.

[0033] In summary, the dual-cold-source deep constant-temperature dehumidifier unit of this embodiment, through the dual-cold-source design, can optimize energy consumption under different operating conditions, significantly reduce operating costs, and can quickly respond to environmental changes, maintaining constant temperature and humidity, making it suitable for various climatic conditions and ensuring a comfortable experience for users in different environments; in addition, the design of the air supply module 101 enables the airflow to be evenly distributed on the evaporative heat exchanger 104, improving dehumidification efficiency and avoiding the local over-humidification or over-dryness phenomenon commonly found in traditional equipment.
