What environment is used for performance testing of smoke exhaust fire dampers

Release time:

2021/07/21 10:55

There are two testing items for smoke exhaust fire damper products: closing reliability. In 10 closing operations, the fire damper shall be able to be flexibly and reliably closed from the position in the opening and closing operations. All parts shall be free from obvious deformation, wear and other damage affecting its sealing performance.

The quality of the fire damper actuator must be visible.

Fire dampers, electric fire dampers and fire dampers are installed on the air supply and return air pipelines of ventilation and air conditioning systems. They are usually open. When the smoke temperature in the pipeline reaches 70 degrees, they are closed and can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time. They play the role of smoke isolation and fire resistance. Fire dampers.

In hot summer and cold winter areas, the outdoor air temperature of low-temperature heat pump can reach -20 ℃ in winter, but the dry bulb temperature of winter heating capacity given on the existing air source heat pump unit sample (or nameplate) is 7 ℃ and the wet bulb temperature is 6 ℃. In winter, when the ambient temperature is lower than -10 ℃, in actual operation, the heating capacity of air source heat pump unit in winter is attenuated, there are two reasons for the attenuation of air source heat pump unit in winter operation

2021/07/21 10:42

First of all, according to the form of compression, the air source heat pump is similar to the refrigeration system according to the different forms of compression. It can be mainly divided into three forms: single-stage compression system, double-stage compression system and cascade system. In general, single-stage system is widely used, and double-stage and cascade systems are mostly used in cold areas, such as northern areas.
