The optimum temperature of the ward is: 18-23℃ and the relative humidity is: 50%-60%?
Relative humidity is usually with the temperature, air pressure *** with the role of the human body. Modern medical meteorological research shows that the human body is more suitable for the relative humidity: summer room temperature of 25 ℃, the relative humidity control in 40% -50% more comfortable; winter room temperature of 20 ℃, the relative humidity control in 60% -70%.

Humidity measurement methods:
1, wet and dry bulb temperature table: a pair of side-by-side device, the exact same shape of the temperature table, a measure of air temperature, called dry bulb temperature table, another wrapped to keep the skim gauze soaked in distilled water, called wet bulb temperature table. The smaller the air humidity, the wet bulb surface water evaporation faster, the wet bulb temperature drops more, the greater the temperature difference between wet and dry bulb; Conversely, the greater the air humidity, the wet bulb surface water evaporation slower, the wet bulb temperature drops less, the temperature difference between wet and dry bulb is smaller. Dry and wet bulb temperature meter is the current main instrument for measuring humidity, but not for low temperature (-10 ℃ below) use.
2, hair humidity meter (meter): the use of degreased human hair with air humidity elongation, drying shortened characteristics, made of hair humidity meter or humidity self-marking instruments. Hair humidity meter is usually used in temperatures below -10 ℃.
3, resistive humidity piece: the use of moisture-absorbing diaphragm with the principle of humidity changes in its resistance value, commonly used carbon film moisture-sensitive resistors and lithium chloride humidity piece of two. This type of component moisture measurement accuracy is lower than the wet and dry table, mainly used in radio sounders and telemetry equipment.
4, film moisture-sensitive capacitors: polymer as a medium capacitor, due to absorption (or release) of water vapor and change the capacitance value. It is a delicate production, excellent performance, commonly used in soundings and telemetry.
5, can directly measure the dew point temperature of the instrument. Use must make the inhalation of sample air pipeline to keep clean, otherwise the impurities in the pipeline will absorb or release moisture caused by measurement errors.
