Differences in heat transfer mechanisms
Air source heat pump: achieved through refrigerant, we use water in the heat pump for heat transfer in the final stage, while the air conditioner uses refrigerant as the medium. One is the water cycle, and the other is the fluorine cycle.
In the water cycle, even if the heat pump is off, the water flow will remain in the pipes and keep emitting temperature. This is equivalent to adding a heat buffering process. And if the fan coil or air floor heating machine as the end, the overall humidity is more in line with human physiological habits, and will not cause dry mouth and tongue and other "air conditioning disease."
Air conditioner: The air conditioner adopts "fluorine cycle" to realize heat conduction. The air conditioning outlet discharges a large amount of hot air, but this kind of intense active heat convection program will greatly increase the evaporation of water on the surface of human skin, resulting in dry air, dry mouth and poor comfort.
Differences in operation methods
First: although the air source heat pump is energized throughout the day, when the heating is completed, the unit will stop working to automatically keep warm. Domestic machines generally do not work more than 2 hours a day, so air source heat pumps save more electricity than air conditioning.
Second: air conditioners are used frequently in the summer, but air source heat pump unit, heating and cooling as one, with longer running hours in winter. Under the condition of running the same time, the compressor in the air source heat pump is subjected to a higher integrated load than the compressor in the air conditioner.
