- Can air source heat pumps be used for cooling?
Compared with other heating methods, the biggest advantage of air energy is that it can be used for both cooling and heating. It is used as a cooling source for air conditioning in summer and as a heat source for floor heating systems in winter. Users do not need to purchase additional cooling equipment, saving initial investment and completing home heating and cooling decoration with minimal cost.
This system was initially called “one source and two ends” by the HVAC industry. “One source” refers to the use of air energy cooling and heating units for cold and hot sources, and “two ends” refer to floor heating coils and fan coils. All indoor spaces use water as the heat exchange medium (fluorine machines use refrigerant for heat exchange). In winter, hot water is supplied, and hot water at about 45°C is directly provided from the outdoor unit for floor heating. In summer, cold water is supplied, and low-temperature water is directly sent to the fan coil for cooling.
This system is comfortable because the water temperature can be controlled, and the specific heat capacity of water is the largest. The temperature difference during the heat exchange process is only about 5°C. There is no noise or draft in the room during cooling or heating, and the comfort level is high. The air it blows is very gentle, like a spring breeze, which is very comfortable. Moreover, it does not take away the moisture in the indoor air during operation, keeping the air moist and making people feel warm and pleasant.
- How is the cooling effect of air source heat pump?
First of all, from the design point of view, air energy focuses on heating, and adopts the “heating + cooling” design, which can take into account both heating and cooling, while the air conditioner focuses on cooling, and heating is only an auxiliary function.
If we only talk about the cooling effect, the cooling effect of air conditioner will be better, but the user experience is not very good. When the air conditioner is cooling, the water blown out is dry wind, which makes the skin feel cold and stinging. The cooling of the air energy integrated mechanism belongs to the water source method. The cooling effect in summer is naturally cool, giving people a very cool and not cold comfort.
If it is heating, the air conditioner is used for heating by blowing hot air. Due to thermal expansion and contraction, the cold air in the room sinks, and the feet are often cold air. The hot air blown out by the air conditioner can only linger on the head and cannot reach the feet. Standing on the floor will make people feel less warm.
When air energy is used for heating, the temperature rises from the ground surface, which can maintain a constant temperature of up to 60 degrees, and will not evaporate the moisture in the air. Therefore, when you walk from the cold outdoors into a room with air energy floor heating, you will feel very comfortable. This comfort is not like traditional electric floor heating or radiators, which make people feel that the air is stuffy or dry.
In addition, the biggest feature of air energy integrated floor heating is concealed installation, which will not occupy the area of the room wall, and users no longer have to worry about a corner being occupied. Air energy integrated is comfortable and healthy, especially for families with children and the elderly, air energy air conditioning and floor heating integrated is definitely the most ideal choice.
