Air source heat pumps are becoming more and more popular. Let's introduce three common air source heat pump heating systems.
1. Air source heat pump + fan coil heating system
Advantages
Fan coils are usually concealed in the ceiling, do not occupy the living area space, save space compared to exposed heat sinks, and the air output is relatively gentle, not as dry and uncomfortable as the hot air blown out by air conditioners or electric heaters. At the same time, the fan coil has high heat exchange efficiency, and the heating area will reach the set temperature in a shorter time. Because the outlet water temperature is around 40-45℃, the air source heat pump is very efficient. If a heating/cooling air source heat pump unit is used, it can also replace the central air conditioner to achieve summer cooling.
Applicable places
Applicable to users with non-continuous and intermittent heating needs. For example: supermarkets, restaurants, offices, weekend villas, etc.
2. Air source heat pump + underfloor heating system
Advantages
It is recognized as the most comfortable home heating method, with uniform heating temperature and warmth from the feet, which conforms to the theory of "cool head and warm feet" in traditional Chinese medicine. The hot water temperature required for floor heating is generally around 35-40℃. When the hot water temperature of the air source heat pump is around 40℃, the efficiency is higher.
Applicable places
It is suitable for places that require continuous heating and users who have high requirements for heating comfort. For example: hotels, villas, and families with elderly and children living at home.
3. Air source heat pump + radiator heating system
The hot water temperature required for the radiator is generally required to reach 50--55℃ or above. The higher the hot water temperature, the lower the efficiency of the air source heat pump, because the temperature in winter is originally low, which makes it more difficult for the air source heat pump to obtain heat in the air, the energy efficiency of the heat pump will be greatly reduced, and the energy consumption of the heat pump will increase significantly, and energy-saving heating cannot be achieved.
Advantages
The radiator is instantly heated and heats up quickly; it can be installed openly and is not affected by the floor.
Applicable places
It is suitable for users with low heating heat load, good indoor and outdoor insulation effect, and cannot install floor heating or fan disk after renovation or decoration of old houses.
The above three methods need to be determined according to the actual needs and use environment of the user. Sometimes, multiple methods can be combined for heating, such as installing floor heating in the bedroom and fan disk in the living room.
In addition, the air source heat pump heating system also needs to be equipped with a suitable buffer insulation water tank to achieve better energy saving and heating effects by using the daytime temperature difference and the valley electricity price, and extend the service life of the air source heat pump. In general, through the reasonable configuration of air source heat pump heating methods and standardized installation and other system construction, the air source heat pump heating system can achieve energy saving, environmental protection, intelligent heating, worry-free and money-saving effects.
