Definition of Heat Ventilation and Air Conditioning System

Heat ventilation and air conditioning is an air conditioning system with three major functions of heating, ventilation and air conditioning. It is also called HVAC (heating, ventilating and air conditioning). The most basic The purpose is to complete the monitoring of the surrounding conditions, humidity and temperatureRwanda SugarThe degree of regulation is to meet people’s comfort level with the surrounding environment and someRwanda Sugar Daddy Craftsmanship request. The components of the heat ventilation and air conditioning system include air treatment devices, duct systems, diffusers, HEPA filters, return air, and control and monitoring systems.

Classification (according to the purpose of use)

Comfort air conditioning system

Requires a suitable temperature and a comfortable surrounding environment. It is measured by human feelings. There are no strict requirements for humidity adjustment accuracy, and it is used in housing, offices, shopping malls, movie theaters, museums, gymnasiums, etc.;

The process air conditioning system

is measured based on the temperature and humidity range required by the process. There are certain requirements for adjustment accuracy, and there are also higher requirements for air cleanliness. Used in electronic device manufacturing workshops, precision instrument manufacturing workshops, pharmaceutical manufacturing workshops, etc.

Temperature and humidity monitoring in HVAC system

Comfort air conditioning system

The application areas of comfort air conditioning are offices and residences. This type of general application is standard heating ventilation and air conditioning, and the main purpose is to control Air conditioning equipment that makes the human body feel comfortable and creates a comfortable working or living environment is an important part of building automation. The temperature and humidity range of this type of HVAC system is mainly based on human comfort: the winter temperature is 20 to 25°C, and the relative humidity is 30% to 60%; the summer temperature is 23 to 28°C, and the relative humidity is 40% to 65%. . However, the specific temperature and humidity control range must be determined based on the actual location. In some locations, in addition to considering people’s feelings, the appropriate storage items must also be considered Rwandans EscortTemperature and humidity, such as archives, art galleries, museums, etc.

Technical air-conditioning system

Technical air-conditioning is mainly aimed at industrial childbirth and requires strict air conditioning to better cooperate with childbirthRwanda Sugar Daddy needs to ensure the quality and processing accuracy of product tools, and has higher design requirements for HVAC systems. The focus of the childbirth workshop design is the HVAC system of the clean room, which is the most complex and important system in the clean room facility for RW EscortsRW EscortsQuality control of air tools (air changes per hour, humidity and temperature). The control accuracy of clean room HVAC system for temperature and humidity is higher than that of building automation, especially for electronics and pharmaceuticals.Clean room HVAC systems in industries such as , precision machinery and other industries have very high accuracy requirements for temperature and humidity transmitters. The range of temperature and humidity that needs to be controlled should be determined based on the characteristics of the processed products and processes. For example, the temperature requirement of the clean room of a pharmaceutical delivery workshop is generally 20-24℃, and the relative humidity is generally 45-60%; Semiconductor clean roomRwanda Sugar DaddyThe general temperature is controlled at 20-25℃, and the humidityRwandans EscortThe temperature is controlled at 50-60%RH.

Selection of temperature and humidity transmitters in HVAC systems

When selecting temperature and humidity transmitters for HVAC systems, in addition to considering the measurement range (the temperature and humidity range of HVAC is relatively common and can be covered by ordinary instruments), The following reasons also need to be considered.

Accuracy

Measurement accuracy is an important indicator of temperature and humidity transmission. Every percentage point improvement is a different level for the temperature and humidity transmitterRwanda Sugar DaddyRequested. The accuracy is different, the manufacturing cost is different, and the required expenditure is also different. Different reasons must be considered when comparing. Although the accuracy requirements for building automated HVAC are relatively low, some special places, such as museums and archives, still require relatively accurate temperature and humidity transmitters to ensure the quality of stored items. In addition, from the perspective of energy saving, the stability and accuracy of measurement are also important. In places with strict requirements on temperature and humidity, accuracy is an important consideration for choosing a temperature and humidity transmitter for the HVARwandans SugardaddyC system. Especially for cleanroom HVAC systems, accurate measurement is important to ensure product quality. Taking the temperature of a semiconductor clean room as an example, due to the rigor of the production process, the accuracy of temperature and humidity measurement is very high. A temperature error of 1°C can cause a 0.24um linear expansion of a 100um diameter silicon wafer. Therefore, the temperature is generally required to be accurate to 0.2℃, and some even require it to be 0.1℃.

Drift

As time goes by, due to the influence of external factors and the structural parameters of the transmitter, a certain drift will occur. However, the process and quality of transmitters of different brands are different, and the time when drift occurs There will be a difference in amplitude. If the transmitter will drift in a short period of time and the amplitude is large, it will have adverse effects on the child and increase the cost of use.Therefore, when selecting a temperature and humidity transmitter, you must also consider this parameter and choose a product with a small annual drift.

On-site display

According to different budgets, application objectives and occasions, you can choose a transmitter with or without display. Transmitters with local display capabilities make it easy to check subsequent temperature and humidity readings directly.

Input electronic signals

Temperature and humidity transmitters generally transmit in voltage or current electronic signals through humidity and heat-sensitive elements through a certain circuit. Which electronic signal to choose depends on the temperature and humidity transmission. Which method is supported by the PLC connected to the device?

Installation Method

Some of the temperature and humidity monitoring points of the HVAC system are distributed in the pipes, and some are distributed indoors. Rwanda Sugar must choose an air duct transmitter in the pipeline; a wall-mounted transmitter must be selected indoors. The size of the installation and the difficulty of the Rwanda Sugar Daddy method are also reasons to consider.
