At present, there are many businesses that install ground source heat pumps, and what should be paid

Our family has just finished, this emerging thing is really good, how good is the money to spend, I really have experience.

The air outlet is different from the previous air conditioner, the comfort is very good, there is no cold feeling, it is all hidden and only the air outlet is seen.

are hidden, so we must choose a very sure business to do a good job, there is no room for overhaul after the decoration, so I choose the early stage of the investigation of more things, (overhaul is to destroy your decoration, the cost can not be calculated), but like the train, the design is good, the construction is no problem, this system is still more energy-saving and comfortable, it is recommended that friends actually inspect their construction site, especially under construction, decoration is a troublesome thing, the early stage can not be sloppy, I also inspected more than 6 heat pumps (the actual construction site) is now more satisfied, I chose Beijing Terui cold and warm, the overall feeling of this company, the construction is in order, the installation of the pipe to me to feel strong, formal approach.

At present, there is no problem with cold and heat, I recommend it to everyone, and there is another point, in winter, you can save 10% of electricity by turning on it less, and you can save 10% when the temperature is increased by one degree in summer.

Now there are not too many manufacturers of geopolitical heat pump tubes, Weixing, Jinde, Mingzhu's products can be regarded as other manufacturers, but they must be cautious, they must be suppressed before going down the well, otherwise they will burst after going down the well, and the well will be wasted, and the pipe will not be able to get up.

Brand, construction experience, degree of project subcontracting.

First, the main advantages of ground source heat pump:

Stay away from air conditioning sickness.

Ground source heat pump air conditioner, the air conditioning outlet in summer is softer than ordinary air conditioner, and the elderly and children are not easy to get sick and uncomfortable.

There are no health hazards indoors.

Ordinary fluorine system** air conditioning system, using R410A refrigerant to transfer refrigerant, high-pressure refrigerant, long-term slow leakage is unavoidable, affecting the indoor environment, endangering the health of family members. The ground source heat pump system uses water as the medium to transfer cooling and heat, and there are no health and safety hazards.

In extreme weather, the system runs more stably.

Ordinary ** air conditioner, such as in the summer of the high temperature of more than 40, or in the winter of the low temperature of less than 0, the cooling and heating effect will be worse. The ground source heat pump system relies on the underground soil for heat exchange, which is not affected by the ambient temperature, and the operation is more stable, and the cooling and heating are not affected, and the room is still comfortable and pleasant.

The energy-saving effect is better.

In summer, ground source heat pump air conditioner is about 30% more energy-saving than ordinary ** air conditioner; For heating in winter, ground source heat pump floor heating is about 40% more energy-efficient than gas boiler floor heating.

Green and environmentally friendly. Ground source heat pump air conditioning and floor heating do not require boilers, and there is no exhaust gas, waste residue and waste water discharge, which is conducive to environmental protection.

Less ambient noise.

Ordinary ** air conditioner outdoor unit is installed in the open air, and the environmental noise is large, especially when it is running at night; In the installation room of the ground source heat pump external unit, the ambient noise is relatively small.

The life of the external unit is longer and the maintenance is more convenient.

The life of the outdoor unit of the ordinary ** air conditioner is about 10 years, and the external unit of the fluorine air conditioner corresponds to the internal unit one by one, which cannot be replaced casually, and it is difficult to maintain; The main engine life of ground source heat pump is usually about 15 years, and it is easy to repair and replace.

Comprehensive cost-effective.

The installation cost of the ground source heat pump air conditioning floor heating system may be slightly higher than that of ordinary ** air conditioning and floor heating, but considering the reduction in the use cost brought about by energy saving, the higher part of the installation cost can be recovered by saving electricity costs within 2-3 years.

Second, the main disadvantages of ground source heat pumps:

Larger garden sites are required.

When the villa area is less than 300 square meters, the initial investment cost is much higher than that of the ordinary air conditioning and floor heating system.

The technical and experienced requirements for the installation company are relatively high.

As a new type of air conditioning system that uses renewable energy, ground source heat pump has attracted a lot of attention because it is more energy-efficient than traditional air conditioners. However, in recent years, a large number of brands have emerged in the market, and the quality of the products is uneven and not guaranteed.

1. Whether Lun Hongyu has a production license, registered trademark certificate and 3C certification: ground source heat pump is a professional product with strict technical requirements, first of all, it depends on whether it has obtained the national industrial product production license, registered trademark certificate and 3C certification issued by the state, as a consumer should be cautious!

2. Whether the performance test report is qualified: the higher the COP value detected by the national authority, the more power saving it will be, and a good ground source heat pump is more than 10% higher than the ordinary one, so it can not be cheap when purchasing.

3. Type of compressor: The compressor is the heart of the heat pump unit. At present, the commercial household heat pump unit is the best compressor produced in Italy and the United States, and it is necessary to ensure that it is the original factory, so as to prevent some manufacturers from shoddy and repaired compressors.

Ground source heat pump technology is a technology 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 electrical energy) into shallow terrestrial energy. The term "ground source heat pump" was first proposed by Swiss experts, but began in the United Kingdom and the United States, and is commonly used for heating and cooling.

Ground source heat pump technology has many advantages, renewable resources can be recycled, cost-effective and energy-efficient, and there is also low pollution. But its shortcomings are also indelible, and his determination determines that the use of ground source heat pumps will be limited to a certain extent. It is important to identify the determination of the source heat pump and arrange it according to local conditions.

Ground source heat pump disadvantage 1: site constraints

Ground source heat pump heat exchange is carried out underground, and heat transfer must be carried out by drilling wells, and the site is not large enough to complete the whole process. Therefore, energy exchange cannot be achieved without sufficient space. Therefore, the use of the site will be greatly limited, and some smaller houses cannot realize ground source heat pump heating and cooling.

Ground source heat pump disadvantage 2: high investment

The one-time investment in ground source heat pumps** is very high. There are often ground source heat pumps in high-grade goods, ground source heat pump air conditioning is much higher than the general air conditioning grade, its energy-saving efficiency can reach more than 40 percent, but the buried investment is just the opposite, more than 40 percent higher than the general air conditioner, the high investment part of the ground source heat pump is actually a high return investment, of course, this is under the premise that you have the ability to use the first air conditioner.

Ground source heat pump disadvantage 3: May pollute groundwater

This disadvantage is only available for some ground source heat pumps, especially those that use groundwater for heating and cooling. Due to the particularity of ground source heat pumps, groundwater pollution may be caused, and if the recharge is not good, it may even cause the foundation to subside.

Disadvantage 4: Soil thermal imbalance

This shortcoming is the biggest shortcoming and deficiency of the ground source heat pump at present, due to the large land area of our country, the climate of different regions is very different, the ground source heat pump is mainly used for cooling in the south, and is mainly used for heating in the north, so it has caused the excessive consumption of underground heat in the north, and the heat is over-injected into the ground in the south, and the heat is out of balance. Perennial will make the temperature of the soil liquid early soil unbalanced and destroy the ecology.

With the increase of economic income, the development of ground source heat pump technology and the support and promotion of the state in the ground source heat pump will make up for the shortcomings of the ground source heat pump one by one, and maximize its advantages, but no matter how it develops, the shortcomings of the ground source heat pump still exist objectively, the use of floor heating heat pump must be investigated by experts, draw relevant reasonable conclusions and plans for the installation of ground source heat pumps, and choose a professional installation company with technology and services, Only in this way can the contribution of ground source heat pumps to mankind be maximized.

1. Stable performance and high efficiency.

Ordinary ** air conditioner will affect the work efficiency when the weather is too hot and cold, and the geothermal energy used by the ground source heat pump is very stable, almost all year round constant at about 14 degrees, slightly higher than the average temperature on the surface, so that no matter what kind of extreme weather, cooling and heating are at the high point of efficiency.

2. Environmental protection and pollution-free.

The environmental protection effect of ground source heat pump ** air conditioner is significant, there is no pollution when used, there is no emission of harmful smoke and other wastes, it can be built in residential areas, and its emissions are equivalent to a reduction of more than 38% compared with air energy heat pumps, and energy conservation and emission reduction will be more obvious in combination with other energy-saving measures. Although there is also a refrigerant, it reduces the charging capacity by 25% compared to conventional air conditioning units; The ground source heat pump is a self-contained system, which can be fully sealed before leaving the factory, which greatly reduces the probability of refrigerant leakage. Moreover, the closed system is used to bring its own water circulation, and no groundwater resources are pumped, which truly realizes the effect of energy saving, emission reduction and environmental protection.

3. Long service life.

Normally, the design service life of the unit system of the ground source heat pump is about 25 years, and the underground pipe system is about 50 years, which is longer than the life of ordinary air conditioning systems and heating equipment.

The state is now slowly restricting this again.

Because of its poor comprehensive effect, the key is that it will cause pollution and destruction to geothermal heat and groundwater.

The main benefits are: a multi-purpose machine (refrigeration, heating, and hot water can be taken into account, and there is no need to install hot water equipment separately).

2. Because the ground source heat pump is heat exchange with geothermal heat, it is very energy-saving, saving more than 30% compared with the traditional air conditioner.

3. It does not produce exhaust gas or other harmful substances, which is very environmentally friendly.

Advantages of ground source heat pumps:

1. Ground source heat pump technology is a renewable energy utilization technology.

Ground source heat pump is a heating and air-conditioning system that uses shallow geothermal resources (usually less than 400 meters deep) on the earth's surface as a cold and heat source for energy conversion. Shallow geothermal resources can be called earthenergy, which refers to the low-temperature thermal energy stored in surface soil, groundwater, rivers and lakes to absorb solar energy and geothermal energy. The shallow surface is a giant solar collector that collects 47% of the sun's energy, more than 500 times the amount of energy humans use each year.

It is not limited by geography and resources, and is truly large in quantity and wide in scope and ubiquitous. This near-infinite amount of renewable energy stored in the shallow layers of the earth's surface makes geoenergy also a form of clean renewable energy.

2. Ground source heat pump is an economical and effective energy-saving technology.

The temperature of geoenergy or superficial geothermal resources is relatively stable throughout the year, higher than the ambient air temperature in winter, and lower than the ambient air temperature in summer, which is a good heat pump heat source and air conditioning cold source, and this temperature characteristic makes the ground source heat pump 40% higher than the operation efficiency of the traditional air conditioning system, so it is necessary to save energy and save about 40% of operating costs. In addition, the characteristics of constant geoenergy temperature make the operation of the heat pump unit more reliable and stable, and also ensure the efficiency and economy of the system.

According to EPA estimates, a well-designed and well-installed ground source heat pump can save users 30 to 40% of the operating costs of heating, cooling and air conditioning on average.

3. The environmental benefits of ground source heat pumps are significant.

Compared with air source heat pumps, the pollutant emissions of ground source heat pumps are equivalent to a reduction of more than 40%, and compared with electric heating, they are equivalent to a reduction of more than 70%, and if they are combined with other energy-saving measures, energy conservation and emission reduction will be more obvious. Although refrigerant is also used, the filling capacity is reduced by 25% compared with conventional air conditioning units; It is a self-contained system, which means that the unit can be fully sealed in advance on the factory floor, so the chance of refrigerant leakage is greatly reduced. The plant operates without any pollution, can be built in a residential area, has no combustion, no smoke exhaust, no waste, no need to pile up fuel waste, and does not need to transport heat over long distances.

4. One ground source heat pump is multi-purpose.

Wide range of applications: ground source heat pump system can be used for heating, air conditioning, and domestic hot water, one machine is multi-purpose, and one system can replace the original boiler and air conditioning two sets of devices or systems; It can be applied to hotels, shopping malls, office buildings, schools and other buildings, and is more suitable for heating and air conditioning of villa residences.

5. The maintenance cost of ground source heat pump air conditioning system is low.

All things considered, buildings with ground source heat pump systems can reduce maintenance costs. The ground source heat pump is very durable, its mechanical moving parts are very few, all the parts are either buried in the ground or installed indoors, so as to avoid the harsh climate outside, the underground part can be guaranteed for 50 years, and the aboveground part can be guaranteed for 30 years, so the ground source heat pump is a maintenance-free air conditioner, saving maintenance costs, so that the user's investment can be recovered in about 3 years.

In addition, the service life of the unit is long, all of which are more than 15 years; The unit is compact and space-saving; High degree of automatic control, unattended.
