Single-cooled air conditioners have a much higher COP (heat efficiency) than heating/air conditioning systems. In summer, when the high temperature is above 35 degrees, the energy consumption is low; when the heating is performed in winter, the ambient temperature is too low to achieve an effect, and the lower the outdoor temperature is, the less the air-conditioning host is started. Even if it was started, the cold wind that began to blow out was hard to come by, and the hot air went up. The places where hands could not reach were hot. The place where people were active was cold. In particular, the legs and feet were still cold.
Therefore, heating air conditioners in winter is not the best choice. If you use floor heating, you can consider its cooling performance when choosing air conditioners.

Health and comfort
Floor heating is currently recognized as the most comfortable heating method. Its operating principle is the same as that of the refrigerator—intermittent heating, that is, the room temperature reaches the preset temperature and is automatically kept in a warm state, stops running, and more effective energy saving.
To warm to meet the Chinese medicine "warm foot and cool top" human body supply and demand, gives a good feeling of foot warm and cool head, improve blood circulation, promote metabolism, control of cardiovascular disease, arthritis, old cold leg patients, for the elderly People and children are particularly suitable, which is not comparable to air conditioning.
In addition, there is no air to the floor and the flu does not cause convection of dirty air. The interior is very clean. Air-conditioning heating is through the tuyere blowing hot air, heat transfer, there is a certain heating effect. However, strong air convection can easily cause dust on the ground. At the same time, if the tuyere is not clean, it can spread viruses and bacteria, making the human body vulnerable to dust and viruses.
At the same time, the use of uneven temperature distribution of air conditioners, there is a blind corner of the heating, the air inside the room is hot and cold, it is easy to cause the phenomenon of hot head and cold feet, comfort is not high.

Visually beautiful
The warmth and concealment are high, and the system is mainly buried under the floor, occupying only the floor height of 3.5cm-7cm, and does not occupy other indoor space. Its installation does not destroy the interior decoration and integrates with the decoration. The space saved can make the interior arrangement more flexible and beautiful.
Compared with floor heating, air conditioners occupy more space in the house. If the internal cabinets or on-hook machines not only occupy the interior space, they are also difficult to integrate into the decoration style and have poor aesthetics. For example, the use of central air-conditioning is highly concealed and relatively beautiful.

Cost comparison
100 square meters of floor heating is generally more than 20,000 yuan in the initial installation fee, air conditioning is generally more than 10,000, relatively speaking, air conditioning is much cheaper (if it is central air conditioning, it is more expensive than warm to about 2 times). However, the service life of the floor heating pipe is 70 years, and the service life of the air conditioning is about 10 years. At least 7 air-conditioners must be installed for 70 years. For a long time, the installation cost of air-conditioning is higher than that of floor heating.
When it is used, the heat conversion rate of floor heating is as high as 98%, and when the air conditioning electric energy is converted into heat energy, the heat loss is large. In the specific use, since the floor heating is normally open for 24 hours, the usage fee is generally higher than the air conditioning.

Many friends around me use air-conditioning to warm up, and I don’t understand why I would like to warm it again. Based on the above considerations, I summarize the defects of air-conditioning heating:
Defect 1: air-conditioning heating is easy to get air-conditioning disease, air-drying, more dust, bacteria and more, for a long time there will be feeling hot and dizzy, uncomfortable;
Defect 2: air conditioning heating noise, will affect the night life and rest, uncomfortable;
Defect 3: Air conditioning heating is difficult to start at low temperatures, especially when the temperature is below zero, frequent defrosting, poor heating effect, and uncomfortable;
Defect 4: The energy consumption cost is higher when the air-conditioning is heating, because the energy consumption of the compressor during heating is greatly increased compared with the cooling, and uncomfortable;
Defect 5: air conditioning heating outlet is high, temperature stratification, uneven heat and cold, poor comfort, easy to make people feel thirsty, unable to solve the "cold from the feet from the" health problems, uncomfortable;
Defect 6: Air conditioning heating is fast, cold is fast and uncomfortable.
Why air conditioning is safe and warm?
The invention of air-conditioning is to solve the problem of refrigeration, and heating is its deterrent, that is, there are few air-conditioning systems for cooling and heating in foreign countries. Because in the eyes of foreigners, the addition of these two items is actually a waste of energy.
