In air conditioning systems, what is the machine dew point temperature? We welcome active participation in discussions; the system offers generous rewards for answering questions from VIP members! ! !
The dew point is originally a temperature value, so why is it used to represent humidity? This is because when the water vapor in the air reaches saturation, the temperature is equal to the dew point ； When the water vapor is not saturated, the air temperature must be higher than the dew point temperature. Therefore, the difference between the dew point and air temperature can indicate the degree to which the water vapor in the air is close to saturation. At 100% relative humidity, the temperature of the surrounding environment is the dew point. The lower the dew point compared to the temperature of the surrounding environment, the less likely condensation will occur; this means that the air is drier. The dew point is not affected by temperature, but rather by pressure. It is mainly used for ventilation and dehumidification in air conditioners.

In air conditioning technology, as air passes through coolers or spray chambers, a portion of it comes into direct contact with the tube walls or chilled water and becomes saturated, resulting in the formation of dew. However, a significant amount of the air does not come into direct contact with the cold source; although it still loses heat through heat exchange, its relative humidity remains around 90–95%. The temperature in this state is referred to as the machine dew point temperature.
