Working principle of fan coil unit
2025-07-19The unit continuously recirculates the air in the room or outdoors, cooling (heating) the air through a cold water (hot water) coil to maintain a constant room temperature. In cooling mode, cold water enters through the inlet and circulates through the coil. The electric motor drives the fan to operate, and air enters and exchanges heat with the cold water in the coil to cool it downMore + -
Performance characteristics of smoke exhaust fan box
2025-07-19High temperature resistance performance: High temperature resistant structural plates are used, and the motor and transmission components are installed at the outer end of the fan case, which can emit high-temperature smoke above 280 ℃ and can operate continuously for more than 100 minutes, meeting the requirements of fire smoke exhaust.More + -
Key points for selecting low-noise axial flow fans
2025-07-19Airflow and Wind Pressure: Based on factors such as the actual space size and ventilation requirements of the usage site, calculate the required airflow and wind pressure, and select the appropriate model of fan to ensure that the fan can meet the requirements of ventilation and air exchange.More + -
What are the requirements for setting fire dampers and smoke exhaust valves?
2025-07-19Fire dampers are used in the supply and return air ducts of ventilation and air conditioning systems. They are usually in an open state, and once a fire occurs, when the temperature of the gas in the duct reaches 70 ℃, they will automatically close and meet the requirements of fire resistance stability and integrity within a certain period of time, playing a role in smoke and fire prevention.More + -
The function of fire control valve
2025-07-19Fire control valves (made of materials such as cast iron, cast steel, stainless steel, etc.) do not require alarm linkage control, but must be equipped with a monitoring module to enable the valve to be monitored by the host. When the valve fuse is activated, the fire control valve outputs a signal to the monitoring module, which then outputs a signal to the alarm host. This allows the control center to monitor the condition of the fire control valve in the air conditioning system.More + -
Material and use of smoke and fire dampers
2025-07-19The material of smoke and fire dampers (used to control the flow of smoke in pipelines during a fire) generally includes carbon (C) material, galvanized steel plate (Zinc coated steel), suitable for installation on the supply and return air ducts of ventilation and air conditioning systems. They are usually in an open state and close when the temperature of smoke in the pipeline reaches 70 degrees Celsius during a fire, and can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time, playing a role in smoke isolation and fire prevention.More + -
How much specific information do you know about the selection of fire smoke exhaust fans?
2025-07-19Fire protection features: good high temperature resistance and high efficiency (Draught Fan) is a widely used fan product, and its ultra-high performance has been widely recognized by users. However, when choosing to purchase a fire smoke exhaust fan, it is necessary to understand some product information. How much do you know specifically about this information?More +
