We also refer to the globe-thermometer probe when measuring radiant heat. The room radiation temperature sensor determines the proportion of the radiation that has a real effect or an effective radiant heat on the measurement location. The measurement is based on the technology of the black bulb sensors (black bulb spherical sensors (standard ISO7726)). This equipment allows to detect and eliminate cold spots, so to improve the comfort and the consumption, especially in large premises. When talking about heating of industrial and commercial premises there are metrology devices whose objective is the measurement of radiating component according to the positions of the heat emitter in the premise. The apparent temperature in the middle of the room will be 19.5☌ ((17☌+22☌)/2). How do we calculate the apparent temperature perceived by humans?Įmpirically, inside of a room, the apparent temperature perceived by a human body (or resultant temperature) is the average between the air temperature and the average wall temperature of the room (average radiant temperature). For example: Temperature of all walls (wall, floor, ceiling) = average T of all walls = 17☌ and Temperature of air Tair = 22☌. In a dwelling, you should prefer a radiant heating by far infrared – of quality – specifically designed to generate infrared radiation with a range of up to 4-5 meters. The second key point is the optimal positioning of the heater so that its radiation can reach the opposite walls, the floor, the ceiling, and thus to limit the influence of cold walls.
