The temperature and humidity of the home are suitable

In ancient times, feng shui masters attached great importance to the orientation and sunshine of the house, and often sought the Xiangyang Mansion, and asked people not to live in the shade of the house. If the temperature in the room is too high or too low, it will have undesirable effects.

The microclimate of the residence should be able to ensure the approximate balance of body temperature and heat of the occupants, and prevent the body temperature regulation function from being in a state of tension for a long time, and have a good warm feeling, normal work efficiency and rest and sleep. Maintaining thermal balance or normal body temperature regulation function refers to the body’s heat production, body temperature, skin temperature, skin sweating, heat dissipation, and warm feeling when people are dressed normally, and work quietly or moderately in the house. And the variation range of other related physiological indicators (respiration, pulse, etc.) does not exceed the normal limit. Therefore, the various factors of the residential microclimate must be kept within a certain range, and the relative stability in time and space must be maintained. Under normal circumstances, people spend more time in the living room than in the auxiliary room. Therefore, it is important to ensure that the micro-climate of the room is suitable, and the auxiliary room should be properly considered.

Through experiments and theoretical calculations, the most suitable indoor temperature range in summer is 24℃～26℃; in winter, the room temperature is 19℃～24℃, which is the most comfortable. If the temperature is 18℃～20℃ and the humidity is 60%, the room is also comfortable. This temperature is equivalent to that women will not feel cold when changing clothes indoors in winter. At present, the entire world climate has become warmer, and people’s residential temperature has begun to require high temperatures. For example, the living room and bedroom require 22°C to 23°C, and the restaurant requires 20°C to 22°C. Due to the heat source and activities in the kitchen, it is always desirable to keep the temperature around 20°C.

The indoor microclimate in summer is greatly affected by solar radiation, heat insulation performance of the enclosure structure and indoor ventilation. Therefore, the main purpose is to choose the appropriate internal design of the residence and the reasonable orientation of the main rooms to create a draught, strengthen the greening, shading, and heat insulation of the enclosure structure. When conditions permit, mechanical ventilation and air conditioning can be installed to ensure that the summer room is suitable. temperature. The indoor microclimate in winter is mainly affected by outdoor temperature, heat transfer performance of the enclosure structure, air leakage of doors and windows, and heating conditions. In order to ensure the indoor temperature, a thicker and better thermal insulation structure, closed doors and windows, and Heating equipment and air conditioning, etc.

To ensure the appropriate indoor temperature, the most basic and economical solution is to adopt a suitable building envelope. The building envelope refers to the outer walls, roofs, floors, doors and windows. In order to protect the house from cold and heat, the building materials of the enclosure structure should be as small as possible of the building materials with low thermal conductivity (building materials with thermal conductivity less than ?0.25? are insulation materials). The smaller the thermal conductivity of the building materials, the worse the thermal conductivity. , The greater the thermal resistance, the more conducive to the heat preservation and heat insulation of the building. However, these materials are often soft substances that cannot play the role of structural support, so they are often attached to the building envelope layer to form a thermal insulation structure construction method, which plays a dual role of load-bearing and thermal insulation. Generally speaking, when the thermal conductivity of this thermal insulation structure is less than 1.5, it is considered to meet the requirements. In hot areas in summer, empty bucket walls and roof overhead air layers are usually used to achieve the purpose of heat insulation. The air layer enclosed in the enclosure structure is a good thermal insulation layer, which can produce a certain degree of thermal insulation.

In addition to room temperature, the human body's tactile temperature of building materials cannot be ignored. In a cold day, if our skin touches the cold tiles in the bathroom, the body will feel shivering and shrinking. People's perception of heat and cold is largely influenced by the temperature of the skin. In a house, there are many places where the skin often comes into direct contact. What materials are used in these places will not make people feel uncomfortable when it is cold, so we must take it seriously. Someone actually measured the temperature drop between the sole of the foot and the floor decoration materials. When the ground temperature is 20°C, if it is a wooden floor, the temperature of the sole will drop by 1°C. Due to different materials, the degree of temperature drop is also different. From the experimental results and daily life experience, it is known that the ground is wooden floor, and the surface has a temperature of 17℃～18℃, which will make people feel comfortable. In other words, if the instantaneous drop temperature of the sole of the foot can be within 1 ℃, it is suitable for talents. Therefore, in residential areas where people's skin is often touched, materials with good body feel should be selected. Because of this, people still like to use wood to make furniture, floors, wall skirts, stairs, doors and windows, etc. in the modern era when all kinds of building materials flood the market.

Water is very important in Feng Shui, and there is a winding river or a pond in front of the house, which are considered to be auspicious houses. In addition to the benefits of irrigation, drinking, and sewage, the residences near the water can also maintain a stable humidity in the residential microclimate.

Generally speaking, high air humidity can increase the body's conduction and heat dissipation, causing body temperature to drop, and the functional activities of the nervous system and other systems will decrease, resulting in a series of pathologies. If you live in a cold and dirty environment for a long time, you are prone to catch colds, frostbite, rheumatism, etc. On the contrary, extremely dry air is not good for human health. From a medical point of view, there is a causal relationship between dryness and throat inflammation. The relative humidity in the room is generally required to be 30% to 65%.
