Description

Technical Field

[0001] The invention relates to laboratory ventilation technology and equipment using the same, in particular to a dual-channel multifunctional air-conditioning box. Background Art

[0002] The air conditioners currently used in laboratories have the following shortcomings: single function, unable to convert multiple functions according to the indoor environment; unable to monitor indoor temperature, humidity, pressure and TVOC in real time; unable to convert functions according to demand when indoor temperature, humidity, pressure and TVOC are abnormal.

[0003] Therefore, it is necessary to provide a dual-channel multifunctional air-conditioning box to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a dual-channel multifunctional air-conditioning box.

[0005] The technical solution is as follows:

[0006] A dual-channel multifunctional air-conditioning box includes a box body, in which a drive fan module is provided. The drive fan module cooperates with an air supply duct and a return air duct to ventilate a laboratory. The drive fan module includes a high-speed fan and a slow-speed fan. The drive fan module is controlled by a control module, and the drive module is connected to an air data detection module in the laboratory via a control line to collect air data in the laboratory, and further controls the high-speed fan and / or the slow-speed fan to drive the laboratory for intelligent ventilation. The air data detection module includes a temperature and humidity probe, a TVOC probe, and a pressure probe.

[0007] The steps for intelligent ventilation in the laboratory are:

[0008] 1) Set a normal operating value A for a laboratory, an increased air intake value B for a laboratory, and an abnormal environment value C for a laboratory. Specifically:

[0009] A is a temperature of 20°C, a humidity of 50%, an air pressure of 1013 hPa, and a TVOC concentration of 0.6 mg / m 3 ;

[0010] B is a temperature of 25°C, a humidity of 55%, an air pressure of 1020 hPa, and a TVOC concentration of 0.65 mg / m 3 ;

[0011] C is a temperature of 30°C, a humidity of 65%, an air pressure of 1030 hPa, and a TVOC concentration of 0.8 mg / m 3 ;

[0012] If one of the operating values ​​is reached or exceeded, normal operation, increased air intake, or abnormal high-power air intake will be performed.

[0013] 2) Intelligent switching air intake:

[0014] 2-1) The air data in the laboratory, including temperature, humidity, air pressure, and TVOC concentration, are all lower than A. The slow-speed fan is running at a wind speed of 8-14m / s. At this time, the slow-speed fan is driven for 10 minutes every 15 minutes;

[0015] 2-2) Normal operation air intake program: When any of the air data in the laboratory, including temperature, humidity, air pressure, and TVOC concentration, reaches A, the slow-speed fan will start to ventilate at a speed of 8-14m / s. The slow-speed fan will continue to ventilate, and real-time feedback will be provided to see whether the laboratory data has dropped to a level where the temperature, humidity, air pressure, and TVOC concentration are all below A.

[0016] 2-3) Increased air intake program: When any of the laboratory air data, including temperature, humidity, air pressure, and TVOC concentration, reaches value B, the slow-speed fan stops and switches to the fast-speed fan, with ventilation at a speed of 16-22 m / s. The fast-speed fan continues to operate for ventilation, and real-time feedback is provided to determine whether the laboratory data has dropped to a level where the temperature, humidity, air pressure, and TVOC concentration are all below value A.

[0017] 2-4) Abnormal high-power air intake program: When any of the laboratory air data, including temperature, humidity, air pressure, and TVOC concentration, reaches C, the system switches to simultaneous operation of the slow and fast fans, with the slow fan providing ventilation at a speed of 16-22 m / s, and the fast fan providing ventilation at a speed of 16-22 m / s. Both the slow and fast fans continue to operate for ventilation, and real-time feedback is provided to determine whether the laboratory data has dropped to a level where the temperature, humidity, air pressure, and TVOC concentration are all below A.

[0018] 3) The air in the laboratory, including temperature, humidity, air pressure, and TVOC concentration, if the value is greater than C and lasts for more than 30 minutes, a laboratory abnormality alarm will be issued.

[0019] Furthermore, a return air valve and an exhaust air valve are provided on the box body, the return air duct is connected to the return air valve, and the exhaust air valve is connected to the exhaust air duct.

[0020] Furthermore, a fresh air valve and an air supply valve are provided on the box body, the fresh air valve is connected to the fresh air duct, and the air supply valve is connected to the air supply duct.

[0021] Furthermore, a return air bypass pipe module is provided in the box body corresponding to the return air valve, and a return air bypass valve is provided on the return air bypass pipe module.

[0022] Furthermore, an exhaust bypass pipe module is provided in the box body corresponding to the exhaust valve, and an exhaust bypass valve is provided on the exhaust bypass pipe module.

[0023] Compared with the existing technology, the present invention has two sets of fans with different functional laboratory ventilation treatments to meet the actual indoor needs; by setting temperature and humidity probes, TVOC probes, and pressure probes indoors, the indoor air quality can be monitored in real time; when the indoor temperature, humidity, pressure, and TVOC are abnormal, the controller can achieve smooth switching between different functions.
