Is it better to use a water source heat pump or an air energy heat pump?

Water source heat pump refers to the absorption of heat from the water and then through the heat exchanger to heat the tap water, air energy heat pump refers to the absorption of heat in the air, heating tap water in the heat exchanger, the principle of both is the use of heat pump principle, the difference is that the heat source obtained is different, one is water, one is air, if in the south, the two are not much different, if in the north, the air can be a little better, because the water is frozen, it is more troublesome.

All are very good, each has its own pros and cons, and you can choose according to the actual situation.

It's good whichever you like.

The way of working is much the same, depending on your needs.

The water source heat pump should be more stable and reliable, but the relative cost will be a little higher.

An air energy heat pump is an air source heat pump.

Both air-source heat pumps and water-source heat pumps can cool down and produce hot water.

Air source heat pumps are suitable for use where air is available, but with current technology, they can be used in areas above -25. And it's working very well, and there's already a project running and feedback.

Water source heat pump is suitable for areas with sufficient water resources, such as water sources such as urban domestic sewage, industrial wastewater, mine wastewater, oilfield wastewater and thermal power plant cooling water that are discharged after artificial use, and it is best not to choose natural water resources.

There are three main heat pump technologies used in China, air source heat pump, ground source heat pump and water source heat pump. Heat pumps can be used to heat or cool. During heating, the heat released by the condenser is sent to the shed for heating by using the hot end of the refrigeration circulation system; When cooling, the working principle is similar to that of a general air conditioner.

The operation process of the heat pump is like pumping the energy from the low end to the high temperature section, so it is called a heat pump. The evaporator of the heat pump is placed in the outdoor air, which is called an air source heat pump; The evaporator is buried in the water through a pipe, which is the water source heat pump.

Advantages of water source heat pump:

It belongs to the utilization of renewable energy technology, green and environmental protection; One machine is multi-purpose, with a wide range of applications; Low operating and maintenance costs; High efficiency and energy saving (the cooling and heating methods with the highest energy efficiency ratio in the current air-conditioning system); The temperature fluctuation of groundwater throughout the year is small, and the machine runs stably.

Apply restrictions. Limited by water source conditions, it is required to meet a certain temperature, water volume and cleanliness; Considering that pumping and recharging requires the use of the geological structure of the site; The return on investment, in general, the water source heat pump has high operating efficiency and low cost, but the investment economy of the water source heat pump will be different under the condition of different needs in different regions.

Air Source Heat Pump Advantages:

Wide range of application (-7 to 40); It can be used all day of the year, and there is no need to be on duty; Fully automatic operation; The operating cost is lower than that of gas and electric boilers; Environmentally-friendly products, pollution-free; Long service life and low maintenance costs.

Apply restrictions. The regional characteristics are obvious, dependent on the external ambient temperature, the normal working environment is between -5 and 40, suitable for the central and southern regions, and the area where the external ambient temperature is too low has frost problems, resulting in a decrease in the energy efficiency ratio; Air energy is a decentralized energy source, and the heating rate is slower than that of water source heat pumps, and the thermal efficiency is lower.

According to the information you provided, I found that ground source heat pump and air source heat pump are specific types of heat pump technology, heat pump technology is an energy technology in the 21st century, with the main performance of environmental protection and energy saving. Among them, ground source heat pump technology is a new type of energy utilization technology, which mainly uses ground energy to realize the role of air conditioning technology for heating and cooling, and the current ground source heat pump system is also widely used in life. The air source heat pump technology is based on the principle of reverse Carnot cycle and establishes an energy-saving and environmentally friendly heating technology, the air source heat pump water heater is mainly used for heating or hot water, and it is also a good way to choose equipment.

However, I recommend the ground source heat pump, which has the advantages of high efficiency, energy saving and environmental protection, and is an ideal "green air conditioner". Among them, the ground source heat pump air conditioning system is more and more favored by consumers, and people are keen on its specific purchase. The air source heat pump has the specific advantages of low energy consumption, high efficiency, fast speed, good safety and strong environmental protection.

Under normal circumstances, the energy efficiency ratio of water source heat pump is higher than that of air source heat pump, and the operating cost is low, but it is necessary to have a special machine room to place the unit, and two wells need to be drilled or there is stable surface water nearby, and the initial investment is slightly higher. Air source heat pumps have a low energy efficiency ratio, are obviously affected by air temperature (especially in winter when the outdoor temperature is low, auxiliary heating may be required), and the operating cost is high. However, there is no need for a machine room, and the unit can be placed on the outdoor floor or roof, and the initial investment is slightly lower.

Each has its own characteristics, and can be selected according to your own requirements and nearby resource conditions.

An air energy heat pump is an air source heat pump.

Both air-source heat pumps and water-source heat pumps can cool down and produce hot water.

They all have their own merits, and nothing is better than the other. I can only say that that one is more suitable for you. This depends on the on-site environment.

As for power saving, the water source heat pump is more power-saving than the air energy heat pump, and the water energy heat pump used in Zhengzhou is OK.

Recommendation: If geology can. Ground source heat pumps can be considered.

than solar + air source heat pumps. The effect is more significant.
