Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, and in particular to an energy-saving constant temperature and humidity air conditioning unit. Background Technology

[0002] Currently, in order to achieve and maintain constant temperature and humidity, air conditioning units are equipped with cooling and dehumidification and heating and humidification equipment. Especially in summer, constant temperature and humidity air conditioning units are used to dehumidify and dehumidify in order to solve the problem of excessive humidity during the summer rainy season.

[0003] However, most constant temperature and humidity air conditioning units on the market currently use fixed-speed compressors. When cooling and dehumidifying in summer, the constant temperature and humidity air conditioning units often have to operate under partial load and heating and humidification conditions, resulting in higher energy consumption of the fixed-speed units themselves. At the same time, after dehumidification, they need to be heated, which requires a lot of electricity, thus increasing energy consumption to a certain extent. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an energy-saving constant temperature and humidity air conditioning unit to solve the technical problems mentioned in the background.

The channel is provided with an air inlet section, a primary / medium efficiency filter section, a heating section, a pre-cooling section, a dehumidification section, a humidification section, a cooling section, an air outlet section, and a terminal filter section in sequence. The air conditioning unit is provided with a radiator and two evaporators. The radiator is located in the heating section, and the two evaporators are respectively located in the pre-cooling section and the cooling section.

[0006] Preferably, both the air inlet section and the air outlet section are equipped with fans.

[0007] Preferably, a rotary dehumidifier is installed in the dehumidification section.

[0009] Preferably, the outer port of the air inlet section is provided with an air inlet, and the outer port of the terminal filter section is provided with an air outlet.

[0010] Preferably, the primary / medium efficiency filter section is equipped with a fresh air inlet.

[0011] Preferably, both the radiator and the two evaporator sections adopt a finned tube structure.

[0012] By employing the above technical solution, this utility model provides an energy-saving constant temperature and humidity air conditioning unit, which has at least the following beneficial effects:

[0013] This invention relates to the air handling section of an air conditioning purification system. The air conditioning unit installs the evaporator of the refrigeration system within the pre-cooling and refrigeration sections of the air being processed. It utilizes the direct evaporation of refrigerant to cool the air. As the air flows over the outer surface of the evaporator, its moisture content decreases while it is being cooled.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Figure 1One embodiment of this utility model: An energy-saving constant temperature and humidity air conditioning unit includes a channel 1 for maintaining constant temperature and humidity and an air conditioning unit 2. The channel 1 is sequentially equipped with an air inlet section 3, a primary / medium efficiency filter section 4, a heating section 5, a pre-cooling section 6, a dehumidification section 7, a humidification section 8, a cooling section 9, an air outlet section 10, and a terminal filter section 11. Air is introduced through the air inlet section 3, and the primary / medium efficiency filter section 4 performs preliminary filtration of dust and impurities in the air. The heating section 5 heats the incoming air, reducing the need for steam heating. The pre-cooling section 6 utilizes the evaporators 13 distributed within it for heating. The refrigerant is directly evaporated to pre-cool the air. Dehumidification is achieved through the dehumidification section 7, and the air humidity is increased through the humidification section 8. The refrigerant applied by the evaporator 13 distributed inside the refrigeration section 9 is directly evaporated to cool the air, thereby reducing the moisture content. The air is blown outward through the air outlet section 10, and the final filtration of dust and impurities in the air transported in the channel 1 is completed through the terminal filter section 11. The air conditioning unit 2 is equipped with a radiator 12 and two evaporators 13. The radiator 12 is installed in the heating section 5, and the two evaporators 13 are installed in the pre-cooling section 6 and the refrigeration section 9, respectively.

[0020] Both the air inlet section 3 and the air outlet section 10 are equipped with fans to blow and induced air. The dehumidification section 7 is equipped with a rotary dehumidifier that periodically rotates a wheel made of moisture-absorbing material. Through the high hygroscopicity of the material, moisture in the air is adsorbed onto the wheel and then desorbed from the wheel by airflow, thus achieving dehumidification. The humidification section 8 is equipped with a humidifier that releases water vapor or mist into the air to humidify the air inside the channel 1. The outer port of the air inlet section 3 is equipped with an air inlet 14 for return air, and the outer port of the terminal filter section 11 is equipped with an air outlet 15 for supply air. The primary / secondary efficiency filter section 4 is equipped with a fresh air inlet 16, which introduces fresh air to maintain the freshness of the air inside the channel 1. The radiator 12 and the two evaporators 13 all adopt a finned tube structure. The fin design increases the surface area of ​​the radiator 12 and the evaporator 13, improving the heat transfer efficiency of the radiator 12 and the heat exchange efficiency of the evaporator 13.

[0021] The specific implementation process is as follows: During use, the fans inside the air inlet section 3 and the air outlet section 10 are turned on to allow air to circulate inside the channel 1. During the air circulation process, the evaporator 13 of the refrigeration system of the air conditioning unit 2 is installed in the pre-cooling section 6 and the refrigeration section 9 of the channel 1 where the air is being treated. The air is cooled by the direct evaporation of the refrigerant. When the air flows over the outer surface of the evaporator 13, it is cooled and the moisture content is reduced. With the cooperation of the rotary dehumidifier and humidifier installed in the dehumidification section 7 and the humidification section 8, constant humidity regulation is achieved in the channel 1. At the same time, the radiator 12 on the air conditioning unit 2 installed in the heating section 5 heats the air introduced into the air inlet section 3. In addition, the filters installed in the primary / medium efficiency filter section 4 and the terminal filter section 11 can effectively filter dust and impurities in the air and maintain the freshness of the air.

[0022] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
