What is the difference between air source heat pump and ground source heat pump and which is better

Air source heat pump: To put it simply, the air source heat pump is to use a small amount of electric energy to process the outdoor air, and transport the comfortable temperature that meets our needs to the room, in this process, the air source heat pump consumes electrical energy to do two work, that is, to make the outdoor air temperature reach the required temperature, heat up or cool down, which is the work of outdoor air, and the other is to transport cold and hot energy to the room, which is the work of handling. The air source heat pump is affected by external natural factors, when the outdoor ambient temperature is very high, it is difficult to discharge the indoor hot air, the cooling effect in the room is poor, and when the outdoor temperature is very low in winter, there will be frost phenomenon in heating.

So natural factors have a great influence on air source heat pumps.

Ground source heat pump: The ground source heat pump uses renewable energy, consumes a small part of electrical energy through the underground soil, converts it with the energy contained in the soil, and transports it to the room through a heat exchanger and carrier, and plays a heating role in winter. In the summer, the indoor heat is transferred to the underground through the unit to play a cooling role.

In this process, the ground source heat pump only does the work of handling, which is the reason why the ground source heat pump air conditioner is more energy-efficient than the air source heat pump air conditioner, which can save 40-60 energy compared to the air source heat pump. The ground source heat pump air conditioning system works underground, which is completely unconstrained by external natural conditions, and operates stably, with multiple uses and low carbon and environmental protection.

1. The working principle is different

Air source heat pump air conditioning and ground source heat pump are energy-saving and environmentally friendly cooling and heating equipment systems, is the use of advanced heat pump technology for energy conversion system, ground source heat pump is the use of soil heat for energy conversion, air source heat pump is the use of continuous solar radiation heat in the air, the heat into the required energy, so as to achieve the process of cooling and heating.

2. The installation conditions are different

The premise of the installation is that the conditions for drilling wells are required, and the initial cost will be relatively high, suitable for villas, schools, factories, office buildings and other places. The air source heat pump air conditioner does not need to drill wells, only needs to have air, and the space is relatively small, and it is suitable for more buildings.

3. The difficulty of operation is different

The air source heat pump only has the main engine and the end, which is relatively simple to operate, while the ground source heat pump has the main engine, the end and the underground pipe system, and the system is relatively complex.

4. The initial investment cost is different

Air source heat pump air conditioner is relatively simple in terms of installation, does not require special equipment, from procurement, installation to the laying of floor heating is relatively easy, the initial investment cost is calculated according to the actual area.

The ground source heat pump needs to drill wells, and the cost of drilling is to see how deep the well needs to be drilled, and the deeper the cost, the higher the cost, plus the cost of equipment installation, etc., which will be slightly higher than the initial investment.

5. The degree of stability is not the same

The ground source heat pump is slightly more stable than the air source heat pump, the ground heat pump is the process of cooling and heating realized by using the principle of soil heat exchange, the soil temperature is constant, and the air source heat pump is the use of air for energy conversion, when the outdoor temperature is too high or too low, the stability is not as good as the ground source heat pump.

Air energy (source) heat pump, as a kind of heat pump technology, has the reputation of "the porter of natural energy", air energy (source) heat pump can not only heat in winter, but also cool in summer, with low cost, easy to operate, good heating effect, safe, clean and other multiple advantages. In fact, air source and air energy and air source are the same meaning, but there is a difference in the name of the north and south.

Of course, air source heat pumps are also divided into several categories, household air source hot water heat pumps, air source commercial hot water heat pumps, air source swimming pool special heat pumps, you can choose the type you need! From the perspective of environmental protection, energy saving and safety, Jinmu air source swimming pool special heat pump is now the first choice for swimming pool water heating equipment. Because it has a variety of unique advantages:

1) Low input and high efficiency, the air source heat pump absorbs the free energy in the air and converts it into swimming pool hot water by the heat pump principle, which solves the problem of high energy consumption in the traditional boiler heating process, and the heat pump unit directly exchanges heat, removing the intermediate links, which improves the work efficiency and reduces the system operation cost;

2) Full function, an air source heat pump unit with dehumidification cabinet can provide three functions of swimming pool constant temperature, heating and dehumidification at the same time, the system is simple to operate, and the protection function is complete;

3) Energy saving, using air source heat pump as swimming pool heating system, high operation efficiency, especially in the two modes of heating and dehumidification at the same time, the energy saving effect is more significant;

4) Environmental protection, the use of air energy heat pump to heat the swimming pool to maintain its constant temperature, water and electricity isolation during operation, compared with the gas heating system, the whole heating process has no combustion, no exhaust emissions, and truly realizes energy conservation and environmental protection.

Air source heat pump and air energy heat pump are actually the same product, but there is a slight difference in name. Why is it called differently? According to different heat sources, heat pumps are divided into air source heat pumps, ground source heat pumps, and water source heat pumps, and the air source is air.

It's just that the name is different, it's actually the same product.

Ground source heat pump and air source heat pump technology as a new energy technology gradually into people's lives, to our life has brought great changes and convenience, so how to choose between the two, what is the difference between the hidden source heat pump and air source heat pump technology, let's take a look.

In order to obtain the comfortable temperature we need, we use the heat pump to heat and cool the outdoor air, and transport the comfortable temperature that meets our needs to the room after processing, which is the principle and process of the air source heat pump air conditioner.

Ground source heat pump air conditioner only does one work, the earth is the largest solar carrier, the surface of the soil and groundwater below 6 meters of soil and groundwater temperature is constant all year round at 10 18. The ground source heat pump consumes a small part of the electrical energy to work through the heat exchanger and the carrier, and transports the energy contained in the temperature of 10 18 to the room through the heat pump unit, and plays a heating role in winter; In summer, the indoor heat is transported to the ground through the heat pump unit to play a cooling role, which is the principle and process of ground source heat pump air conditioning. In this process, the heat pump consumes electric energy and only does "one work", which is transportation, which is the reason why the ground source heat pump air conditioner is more energy-efficient than the air source heat pump air conditioner.

Compared with air source heat pump air conditioner, ground source heat pump air conditioner saves 40-60% energy by ground source heat pump.

Air source heat pump air conditioner is limited by natural conditions, and when the outdoor ambient temperature is very high in summer, it is difficult to discharge indoor hot air to the outside, and the room cooling effect is very poor; When the outdoor ambient temperature is very low in winter, there will be frost in the heating, and the effect of the heating fiber hall is also very poor. The ground source heat pump air conditioner is not restricted by natural conditions, the ground source heat pump air conditioner is completely not affected by the ambient temperature, the working condition is stable, and the ground source heat pump will not cause Gaozai environmental pollution and urban heat island effect, which is the most energy-saving "three-purpose" heat pump air conditioning unit.

The above is a summary of the differences between ground source heat pump and air source heat pump, I hope it will help you in the process of choosing an energy system.

1. The working principle is different.

The air source heat pump is an energy-saving device that can make the heat flow from the air of the low heat source to the high heat source with a high position. It is a form of heat pump. Heat pumps, like pumps, can convert low-level heat energy that cannot be directly used (such as the heat contained in air, soil, and water) into high-level heat energy that can be used, so as to achieve the purpose of saving part of the high-level energy (such as coal, gas, oil, electricity, etc.).

Ground source heat pump is a device that realizes the transfer of low-grade thermal energy from low-grade thermal energy to high-grade thermal energy by inputting a small amount of high-grade energy (such as electric energy) into the shallow energy of land. Usually the ground source heat pump consumes 1kWh of energy, and the user can get more heat or cooling.

2. Consumption is different.

The air source heat pump system has no cooling water system, no cooling water consumption, and no cooling water system power consumption. In addition, there have been many reports of Legionella infections caused by cooling water pollution, and from the perspective of safety and hygiene, there are also obvious advantages to considering air source heat pumps.

Ground source heat pumps are a cost-effective energy-saving technology. The COP value of its ground source heat pump reaches more than 4, which means that the user can get more than 4kWh of heat or cold for 1kWh of energy consumption.

3. The application is different.

Air source heat pump water heater is a kind of heat pump water heater that uses air as a low-temperature heat source to produce domestic hot water, which is mainly composed of two parts: air source heat pump circulation system and water storage tank. An air source heat pump water heater is a device that transfers the heat in the air to the water to produce hot water by consuming part of the electrical energy.

The ground source heat pump system can be used for heating, air conditioning and cooling, and can also provide domestic hot water, one machine is multi-purpose, and one system can replace two sets of devices or systems for the original boiler and air conditioning, especially for buildings with heating and cooling requirements at the same time. Ground source heat pumps have obvious advantages.

Not only saves a lot of energy, but also with a set of equipment can be seen to meet the requirements of heating, cooling, domestic water at the same time, reducing the initial investment of equipment, ground source heat pump can be used in hotels, residential quarters, apartments, factories, shopping malls, office buildings, schools and other buildings, small ground source heat pumps are more suitable for the heating and air conditioning of villa residences.

Summary. To put it simply, an air energy heat pump uses a small amount of electrical energy to drive the whole system to exchange heat with air to heat hot water and release a certain amount of cold air. Hot water is used for domestic use and underfloor heating, and in the summer it is cooled by air conditioning.

Is it better to have a ground source heat pump or an air energy heat pump?

To put it simply, an air energy heat pump uses a small amount of electrical energy to drive the whole system to exchange heat with air to heat hot water and release a certain amount of cold air. Hot water is used for domestic use and underfloor heating, and in the summer it is cooled by air conditioning.

Air energy heat pump system and ground source heat pump system, one uses the energy in the air, the other uses the energy of the earth, is less affected by the weather, both stability and energy saving are better than solar heat pumps, but also better than other similar traditional equipment.

Do you have any other questions?

Advantages: Advantage 1: Its application field is universal.

The air source heat pump can run all year round without being limited by the temperature, constantly heating, without full-time personnel to take care of, and the temperature range that can generally run smoothly is minus 7 to 40, while the air source heat pump of Wofu air energy water heater manufacturer is technically solid, and it can operate normally at an ultra-low temperature of minus 29.

Advantage 2: Low cost of operation. The actual effect of environmental protection and energy saving is very prominent, compared with many electric water heaters, the annual operation cost is low, and the project investment can be recovered in a short time.

Advantage 3: Air energy heat pump air conditioner is an energy-saving product. There is no air pollutant discharge in the whole process of operation, and it will not cause harm to the body, which has excellent social and economic benefits.

Advantage 4: Stable characteristics, not easy to be harmed by the natural environment, complete the 24-hour boiling water supply throughout the year.

Advantage 5: Convenient. Air source heat pumps can be installed in casual indoor spaces without occupying any area.

Having talked about so many advantages, is the air source heat pump also a disadvantage? Let's also talk about the disadvantages of air source heat pumps.

Disadvantage 1: The high efficiency is not high, and it is limited by the region. The air source heat pump digests and absorbs pyrogen gases in a dispersed type, and the heating rate is not very fast, and there is also a point that it is very easy to frost and suffer from regional limitations.

The air source heat pump from Wofu can operate normally in a natural environment of minus 29, so this problem is not to be worried.

Disadvantage 2: The refrigeration compressor is very easy to burn out. At present, the air source heat pump on the market is widely used in the circulating heating system software, which is very easy to embrittle in the natural environment of ultra-high pressure, and if the actual effect of the system software is not very good, it is very easy to cause the refrigeration compressor to be burned.
