[0002] A fresh air system is an independent air handling system consisting of both a supply and exhaust system. It comes in two types: ducted and ductless. A ducted fresh air system consists of a fresh air blower and ducting accessories. The blower purifies outdoor air, introduces it into the room, and exhausts it through ducts. A ductless fresh air system also uses a fresh air blower, which purifies outdoor air and introduces it into the room. Ducted fresh air systems are more suitable for industrial or large office areas due to their large engineering requirements, while ductless systems are more suitable for home use due to their ease of installation.

[0015] The working method of the water system partition five-constant full air system includes the following specific steps:

[0016] S1. Start the main air supply fan through the touch screen. The outdoor fresh air and indoor return air are filtered by the main air supply fan in sequence through the primary filter, medium efficiency filter and high efficiency filter;

[0017] S2. The filtered air passes through the surface cooler, evaporator, condenser, and wet film, and is sent to different areas under the action of the zoned air supply fan;

[0018] S3. The water supply and return pipes are connected to the surface cooler, and low-temperature water circulates inside. The air passing through this surface cooler is cooled and dehumidified.

The main air supply fan with adjustable pressurization function is to adapt to the wind pressure of different numbers of partition air supply fans, to prevent the wind pressure from being too high when one partition air supply fan is working, or the wind pressure from being too low after the dispersed wind pressure is caused by the simultaneous operation of multiple partition air supply fans, and to ensure the stability of air supply.

[0023] Fourth, the return air vent of the present invention is used to receive complex indoor wind. Due to the existence of indoor wind in a small room and human activities, the concentration of volatile substances, particulate matter, carbon dioxide content and other objects will be significantly different from the external wind. In order to effectively monitor such substances and effectively treat them, two groups of five-in-one sensors are set at the return air vent to monitor the PM content, TVOC content, carbon dioxide content and temperature and humidity of the incoming wind, and transmit them to the touch screen display panel to display each measurement information and display it on the touch screen display panel by taking the average value. Such a setting will further improve the measurement accuracy of the equipment, and in the event that one five-in-one sensor is damaged, it can ensure that the other five-in-one sensor can also work normally, thereby ensuring that the equipment can operate normally and is safer.

[0024] Fifth, the present invention sets two groups of temperature and humidity sensors in the fresh air inlet and several partitioned air supply outlets in order to measure the temperature and humidity of the fresh air and clean air through the two groups of temperature and humidity sensors, and display them on the dew point control panel by taking the average value. Such a setting will further improve the measurement accuracy of the equipment, and in the event that one temperature and humidity sensor is damaged, it is guaranteed that the other temperature and humidity sensor can also work normally, thereby ensuring that the equipment can operate normally and is safer.

[0035] Two sets of temperature and humidity sensors 13 are installed at the fresh air inlet 2 and the plurality of partition air supply outlets 4.

[0036] The fresh air inlet 2 is a channel for inhaling outdoor air into the room, and the partition air supply outlet 4 is a channel for transporting the clean air processed by the partitioned equipment to the spaces in each sub-chamber. Two groups of temperature and humidity sensors 13 are set in the fresh air inlet 2 and several partition air supply outlets 4. The purpose is to measure the temperature and humidity of the fresh air and the clean air through the two groups of temperature and humidity sensors 13, and display them on the dew point control panel by taking the average value. Such a setting will further improve the measurement accuracy of the equipment, and in the event that one temperature and humidity sensor 13 is damaged, it can ensure that the other temperature and humidity sensor 13 can also work normally, so that the equipment can be guaranteed to operate normally and be safer.

[0037] The fresh air temperature and humidity sensor 13 transmits the temperature and humidity of the fresh air inlet to the control unit of the touch screen for data reading.

[0044] The air supply assembly includes a main air supply fan 19 fixedly connected to the support plate 5, and a partition air supply fan 20 installed at the bottom of several partition air supply ports 4. The partition air supply fan 20 is equipped with a partition air valve 21 in the partition air supply port 4.

[0045] Each partition air valve 21 corresponds to a partition air supply fan 20. Each partition air supply fan 20 and partition air valve 21 are individually controlled by a dew point control panel. When the dew point control panel controls one or more partition air supply fans 20 to stop working, the corresponding partition air valve 21 on each partition air supply fan 20 is automatically closed to prevent backflow. The main air supply fan 19 is set at the bottom center position of several partition air supply fans 20 and provides pressurized air supply function for several partition air supply fans 20.

[0046] This equipment solution adopts a setting scheme of six partition air supply ports 4. Therefore, six partition air supply fans 20 and six partition air valves 21 are set accordingly, and are independently controlled by six independent dew point controllers.

[0047] The purpose of setting up the corresponding partition air valve 21 on each partition air supply fan 20 is to better control the opening and closing of each partition distribution port 4, to prevent the return air problem from affecting the working partition air supply fan 20 after one or more partition air supply fans 20 stop working, and to avoid secondary pollution. The main air supply fan 19 with adjustable pressurization function is to adapt to the wind pressure of different numbers of partition air supply fans 20, to prevent the wind pressure from being too high when one partition air supply fan 20 is working, or the wind pressure from being too low after the dispersed wind pressure is caused by multiple partition air supply fans 20 working at the same time, and to ensure the stability of distribution.
