1, room temperature: the suitable temperature range for central heating rooms is 16 ~ 20℃, for decentralized heating rooms is 13 ~ 17℃, and the indoor temperature in any area in winter shall not be lower than 65438+.

2. Vertical temperature difference: refers to the difference between the temperature at 0. 1 m above the ground and the temperature at 1.5 m above the ground. The vertical temperature difference is too large, the foot temperature drops, and the body temperature regulation is tense, which is not good for health. General vertical temperature difference should be less than 3℃.

3. Horizontal temperature difference: refers to the temperature difference between indoor points at1.5m.. Generally, it is easy to catch cold in doorways, windows, corridors and other places, and the indoor horizontal temperature difference is too large, so the horizontal temperature difference should not exceed 2 ~ 3℃.

Heating is the earliest developed building environment control technology. Since people know how to use fire, in order to resist the threat of cold to survival, they have invented heating methods such as kang, stove, fire wall and fire ground. This is the earliest heating equipment and system, and some of them are still in use today. Today, heating equipment and systems have made great progress in human comfort and hygiene, beautiful and dexterous equipment, automatic control of systems and equipment, diversified system forms, effective use of energy and so on.
