Ground source heat pump and air source heat pump how to choose? What's the difference?

Ground source heat pump and air source heat pump popularity, but also so many users in the choice of entangled, do not know which one is good? Do not know how to choose?

Both ground source heat pump and air source heat pump are energy saving and environmental protection heating and cooling equipment systems, which are all systems that utilize advanced heat pump technology for energy conversion. However, their conversion methods are not the same: ground source heat pump is the use of soil heat for energy conversion , While the air source heat pump is the use of air source heat pump technology for energy conversion, but there are some differences between the two.

1. Ground source heat pump more energy efficient, but need to dig wells, the installation needs to have the conditions of drilling, the initial cost will be higher, suitable for villas, schools and other places.
2. Air source heat pump does not require drilling, just need air on it, covers an area of space is relatively small, suitable for high-rise buildings.
3. Ground source heat pump host, end and underground buried pipe systems, and air-source heat pump only the host and the end, the relative operation is relatively simple.
4. Ground source heat pump than the air source heat pump temperature stability, ground source heat pump is the use of soil heat transfer method, the soil temperature is relatively constant throughout the year, and the air source heat pump is the use of air.

Both ground-source heat pump and air-source heat pump are energy-saving and environment-friendly energy systems, each with its own advantages. Users should choose suitable and suitable ones according to their actual conditions to achieve the maximum effect.

What are the two installations or trigeneration of air source heat pump

Air source heat pump technology from Europe, which has been widely applied in developed regions such as Europe, the United States and Janpan. Air source heat pump technology is mature, there are many kinds products. But the development of air source heat pump in China but also more than 10 years of time, nearly two years with governance environment pollution, promote clean energy use, air source heat pump products slowly into the public eye, in 2016, the north of China coal to electricity, greatly promoted the popularization of air source heat pump heating.  

Air source heat pump in China has experienced the hot water, heating, cooling, drying and so on several stages, the specific representative of products for, air source water heater, air source two installations, air source trigeneration, air source drying equipment etc. Air source water heater and air source drying equipment from the literal can understand what product, what effect, but what exactly are the two installations and trigeneration ?

We all know the working principle of air source heat pump is refrigerant obsorption of low temperature heat in the air, through the compressor compressed into high-temperature heat, hot water, high temperature heat can be converted to again so it is the application of air source heat pump is the most primary air source water heater, direct and simple technical requirements is low. Air source heat pump technology to demand higher belongs to heating, cooling and drying field. In order to realize heating of the air source, in the end usually use floor heating system. To achieve refrigeration, air source in the end usually use central air conditioning system. 

So two installations is the use of a set of air source heat pump system, provide hot water, heating or provide heating, cooling, two functions, so the air source two installations are collectively, floor heating and air conditioning or , floor heating and hot water machine. The trgeneration is air conditioning+floor heating + hot water machine. Then many people will ask that why can’t two installations are refrigeration +hot water? This is from the design concept for the air source heat pump, at the beginning of the design but with the development of air source heat pump technology, comprehensive user’s demand to the refrigeration, the consolidation of refrigeration in the air source heat pump system, the function of the refrigeration is belong to the second and third. It’s like at the beginning of the air conditioning design is used fro cooling,k with the air conditioning technology development, can also provide heating, air conditioning refrigeration powerfull effect not only.
