The working principle of the air source heat pump is to absorb the low temperature heat in the air. In the whole heating process, electricity is only auxiliary energy. It is 400% energy saving higher than the electric water heater. The air source heat pump is regarded as the new generation of environmental friendly energy saving equipment after the solar energy. It achieved great success in the "coal to electricity" project in the northern province, and was unanimously recognized by users.
The terminal devices of the air source heat pump mainly include floor heating, radiators, and fan coils. Which one is more advantageous among the three?
Floor heating
Floor heating is a kind of radiant heating. The air source heat pump unit heats the water to 35-45 ° C. Then it circulates through the pipes under the floor to heat the whole indoor space. The temperature of air reduces from bottom to top. Warm on the feet and cold on the head is in compliance with the principle of traditional Chinese medical health. Floor heating is the best way for room heating in winter. Compared with the traditional heating method, the floor heating is continuous, slow and evenly radiating to the room. The human body feels the warmth in all directions, and there is no hot wind directly blowing on the skin, therefore it will not take away the body's water, the body is more moist.
Radiator
The principle of heat radiator is that hot water flows inside of it, dissipating heat outside and raising the room temperature. Therefore, hot water temperature often needs to reach 60 °C. In order to provide high-temperature hot water, the air source heat pump needs to consume more electricity. Besides, the limitation of heating range is the biggest defect of the radiator heating application. The radiator can only provide heating for a part of but not the whole area of the room. Only certain area in the room can feel warm but it can not reach the constant temperature heating of the whole room space. If you walk in the room, there will be a feeling of sometimes cold and sometimes hot. However, the radiator also has its own unique advantages - generally installed in the corner, it is revealed mounting, easy to install. From the aspect of comfortability, the radiator is not as good as the floor heating.
Fan coil
The fan coil is rare in small residential houses. It is common in large factories and large villas. According to the different installation methods, the fan coil are divided into two categories, one is to wall hang type , and the other is to floor standing type. The fan coil receives the hot water sent by the heat pump, exchanges the heating in the water to the room air and thus raise the room temperature. In conjunction with the "water circulation" system of the air source heat pump, the outlet air is just right and not dry. Because of the active heat convection heating, the hot air temperature required by the fan coil is not high, and it is more energy efficient in combo with the heat pump. The disadvantage is that the wall hang installation is not easy, you need to punch holes, and also install sockets on the wall. Furthermore, the wind coming out from above the head makes people feel stuffy.
Power World air source heat pump predicts that the most comfort terminal device is floor heating, combining with the fan coil, winter heating gives users a totally different experience. while, the radiator will be gradually replaced.
