HVAC

Winsen provides a comprehensive solution for air-conditioning enterprises. It not only has high-quality miniaturize integrated air quality detection modules, but also develops infrared temperature sensor to intelligently adjust the air volume and wind speed to guarantee the whole system running smoothly

Hot-selling air quality detection module:ZEHS01

▲ ZEHS01 air quality detection module

Winsen established a special R&D team to develop a high-end module designed for air quality detection and very suitable for ventilation systems: ZEHS01. It is a integrated sensor module of the electrocochemical formaldehyde sensor (or VOC sensor), PM2.5 dust sensor, infrared CO2 sensor and temperature and humidity sensor. This product is small in shape and has the characteristics of good consistency, stability, accuracy, multi-detection intelligence. It is very convenient to integrate into the purifier and fresh fan, which can intelligently sense the change of air quality. In real time, PM2.5, carbon dioxide, formaldehyde (or VOC), temperature and humidity are displayed in real time.(Formaldehyde sensors can be replaced with VOC sensors based on customer needs)

ZEHS01 all-in-one sensor module has developed a variety of external communication interface methods such as RS485, serial TTL, IIC, etc., and adopts isolated power supply and isolated 485 module to ensure stable operation of the module in complex scenes; The built-in standard MODBUS-RTU communication protocol realizes the master-slave control mode of bus communication,and the customer's host device can connect up to 256 modules as slave devices to realize distributed air quality detection and flexible sensor layout. The product is truly designed from the perspective of customer experience, and intelligent integration makes everything simple. For some customers who are not very proficient in sensors, it is also easy to use.

Farewell to the traditional winding style—infrared temperature sensor applies to air conditioning

When using traditional air conditioners, we will find that the air conditioner's output and position are fixed. The position near the air outlet is easy to be blown and cause a headache, and the position of the air outlet will not feel the cool wind. The fixed way of air conditioning cannot actually meet people's needs.

The new intelligent air conditioner detects changes in human activity in different directions in the room through infrared temperature sensing technology. It automatically adjusts the temperature and air volume through the AI intelligent algorithm, ensuring the comfort of the human body while achieving energy conservation and environmental protection.

Winsen Technology's MRTD-3011 is a fully integrated digital thermopile sensor with a separate circuit I2C, using advanced MEMS technology, is currently one of the best-selling models in air conditioning applications.

In practical applications, one or several sensors can also be used to achieve a wider range of measurement according to the situation. This kind of intelligent air conditioner does not need to repeatedly adjust the temperature, and automatically enters the energy-saving mode after reaching the set ideal temperature. And it can be adjusted according to changes in body temperature during sleep to ensure sleep quality. At the same time, if you encounter a sudden drop in temperature, you don't have to worry about being "frozen awake" in the middle of the night.

Pressure sensor—maintaining the detection area, improving the efficiency of the air-conditioning system

In the central air conditioner, the controller and end sensor are key components that ensure the smooth operation and keep the system be energy-saving. The filter is used to filter the dust impurities in the ventilation pipeline. The pressure sensor at the indoor ventilation port is used to monitor the pressure difference at both ends of the filter at the outlet. More dust on the filter is accumulated over time, which gradually affect the air circulation. When the air circulation is not smooth, the air pressure difference at both ends of the filter is increasing. When the pressure sensor feels changes in pressure, the upper machine receives a signal from the pressure sensor. When the signal value reaches the alarm point, the alarm will start to remind the cleaning staff to clean or replace the filter. In addition, the pressure sensor also participates in the controlling of the air supply offer.

Fresh air is needed to be flowing to ensure the comfort and health of indoor personnel, the air flow changes according to the function of the building and the number of residents. Sensors are often used to measure air flow and pressure to improve the efficiency of the air conditioning system. Among them, pressure sensors can ensure that a large amount of air is drawn back into the building, and through the evaluation and monitoring of air pressure, quality and ventilation, the breathing of indoor personnel can be guaranteed.

▲ WPAK63 pressure sensor

WPAK63 series is a pressure core packaged with high-precision diffused silicon pressure-sensitive chips and mature production processes. It is the core component of manufacturing pressure sensors and pressure transmitters. As a high-performance pressure-sensitive element. It can be easily amplified and assembled into a transmitter with standard signal output. With Φ19mm standard OEM pressure core, it is highly interchangeable with the same type of products in domestic and foreign markets. All stainless steel 316L package, anti-corrosion, the compensation plate is filled with glue for moisture-proof protection, very suitable for pressure detection of HVAC systems.
