1.	It is quite evident that the incoming air for ventilation should be ________ in summer and ________ in winter before it enters the room.(a) cool, warm(b) warm, cool(c) humid, dry(d) dry, humidThis question was addressed to me in an online quiz.Enquiry is from Types of Ventilation topic in chapter Acoustics and Ventilation of Construction & Building Materials
Answer» CORRECT option is (a) cool, warm The best I can explain: The usual DIFFERENCE of temperature between INSIDE and outside is kept as about 8°C to 10°C. With regards to human comfort, the term effective temperature is used. It is an INDEX which COMBINES the effect of air movements, humidity and temperature.
