1. Green. When heating in winter, the soil-air/water ground source heat pump system does not need a boiler, and there is no emission of waste gas, waste residue and wastewater, which can greatly reduce the emission of greenhouse gases and protect the environment. It is an ideal green technology.
The second is household billing, which realizes independent billing of units and household metering, which is convenient for owners to manage the whole system.
3. Long service life: the design life of household air conditioner is 8 years, and the design life of gas boiler is 10 year; Ground-to-air ground-source heat pump unit has been used for 50 years, water circulation and air duct system for more than 60 years, and ground coupling pipeline system for 70 years, which is longer than all kinds of air conditioning systems and heating equipment.
Fourth, save building space. The control equipment is simple. Soil-air/water ground source heat pump system adopts the way of installing ground source heat pump units in various places (rooms, clubs, offices, etc.). ). Central control only needs waterway control, which saves the complicated link of centralized control of all parameters in general central air conditioners and reduces the control cost. In each decentralized installation unit (bedroom, clubhouse, office), different small terminal controllers can be set according to users' requirements, and the simple (start-stop, heating and cooling) to complex programmable intelligent control mode can be realized.
5. The system is highly reliable, and each unit can provide cooling or heating independently. The failure of individual units does not affect the operation of the whole system. The operating condition of the unit is stable, almost unaffected by the change of ambient temperature, and the heating capacity will not be attenuated even in cold winter, so there is no concern about frosting and defrosting.
Six, cooling and heating at the same time, the soil-air/water ground source heat pump system can realize the simultaneous cooling of some rooms or areas, and heating of some rooms or areas, which is particularly important for large commercial buildings. The traditional central air conditioning system needs to use an extremely expensive four-tube air conditioning system, while the soil-air ground source heat pump can be realized without adding any equipment.
7. Low maintenance cost. Soil-air/water ground source heat pump system has no outdoor installation equipment, cooling tower and roof ventilator, and there is no installation and maintenance cost of outdoor equipment. The compressor works stably, and the phenomenon that the refrigerant pressure in traditional equipment is too high or too low will not occur. Its maintenance cost is much lower than that of traditional central air conditioning.
8. Intelligent remote central control. Intelligent remote control software can use the central computer to control the whole system, and can automatically adjust the cooling or heating of ground source heat pump with the change of human flow, so as to save energy to the maximum extent and reduce the operating cost to the maximum extent. You can also set up display and printing equipment to store and analyze various economic and technical data such as heating, refrigeration and maintenance, so as to promote the optimization of system operation.
Nine, the application is flexible, safe, reliable and flexible. It can be used for new construction, expansion and reconstruction projects, and can be built step by step. The heat pump unit can be flexibly placed anywhere, saving space. There are no health and safety hazards such as coal storage and oil storage tanks.
Disadvantages of ground source heat pump
Compared with the traditional cooling and heating methods, ground source heat pump has obvious advantages, but as a new type of equipment with high technical content and complex system, ground source heat pump also has some shortcomings in its current application.
1, the initial investment of ground source heat pump is relatively high. The initial investment of small household ground source heat pump system is more than 100 thousand yuan, and the cost of large commercial ground source heat pump is higher. Although the later use cost is low, the initial investment of more than 100 thousand yuan still makes many ordinary families flinch. At present, the installation of household ground source heat pump is mostly concentrated in villa users.
2. The ground source heat pump system is complex and difficult to install. Ground source heat pump requires high design, construction and construction site management, and requires the participation of professional and technical personnel. At present, although there are many companies doing HVAC in China, there are not many companies that really have professional ground source heat pump installation and construction technology.
What are the advantages and disadvantages of ground source heat pump heating? Efficient and energy-saving, one thing for three purposes, make full use of ground energy. Generally, the energy consumption of ground source heat pump is 1 kW, and users can get more than 5KW of heat or 4KW of cold energy, which is 40-50% less than that of traditional central air conditioning.
Environmental protection underground energy is renewable energy, without heat pollution, noise pollution and harmful gas emission, which truly realizes energy saving and emission reduction.
Stable and reliable, not affected by external high temperature or cold, stable operation, no health and safety hazards such as boilers and oil storage tanks, the service life of the system can reach 20 years, and the service life of the underground heat exchanger can reach 50 years.
Saving water and land takes soil as the carrier, releasing or absorbing heat to it, without consuming water resources, saving supporting equipment such as cooling tower and boiler room, saving valuable space, generating additional economic benefits and improving the external image of the environment.
The control is simple, controlled by the whole system programmable intelligent remote central computer, and can automatically adjust the cooling or heating output of the ground source heat pump with the change of human flow, so as to save energy to the maximum and minimize the operating cost.
The ground source heat pump system with convenient maintenance has fewer moving parts than the conventional system, thus reducing maintenance. The system is installed indoors, protected from wind and rain, and protected from damage, thus reducing maintenance costs. Provided by Jinyun Shujia
Advantages and disadvantages of ground source heat pump What are the ground source heat pumps? They have good heating effect and energy saving in winter, but their installation is more complicated than air conditioning.
Advantages and disadvantages of ground source heat pump air conditioning
1. Ground source heat pump air conditioning is far away from air conditioning diseases. In summer, the air outlet of air conditioner is softer than ordinary air conditioner, and the elderly and children are not easy to get sick and uncomfortable.
2. There is no health hazard indoors. In the central air conditioning system of common fluorine system, R4 10A refrigerant is used to transfer the cooling capacity. Long-term slow leakage of high-pressure refrigerant is inevitable, which affects indoor environment and harms family health. Ground source heat pump system uses water as the medium to transfer cold and heat, and there is no health and safety hazard.
3. In extreme weather, the system runs more stably. For ordinary central air conditioning, if it encounters high temperature above 40℃ in summer and low temperature below 0℃ in winter, the cooling and heating effect will obviously deteriorate. The ground source heat pump system relies on the underground soil for heat exchange, which is not affected by the ambient temperature, runs more stably, has no influence on refrigeration and heating, and is still comfortable and pleasant indoors.
4. The energy-saving effect is more remarkable.
disadvantaged
1. Installation requires drilling wells and a large garden site.
2. When the villa area is less than 300 square meters, the initial investment cost is much higher than that of ordinary air-conditioning floor heating system.
The article comes from: the advantages and disadvantages of villa ground source heat pump, whether the ground source heat pump is good or not, and Shanghai New Energy.
What are the advantages and disadvantages of applying ground source heat pump in Shanghai when the country promotes ground source heat pump system? The country promotes the ground source heat pump system, and many cities also have project funds subsidies, so they are basically advantages and have no obvious disadvantages.
The advantages of ground source heat pump are: the energy efficiency of the unit is relatively high, energy can be stored in different seasons in winter and summer, the terminal of special air conditioner has the possibility of direct supply, it is clean and renewable energy, and there is no pollution in heating (basically no pollution in refrigeration, compared with ordinary boilers), and the maintenance cost is low.
Disadvantages. . . It is difficult to design, so it is necessary to calculate the annual cumulative load of the building and the heat balance of the underground heat exchanger in winter and summer. In short, there are many things to be simulated, which need professional companies to do with professional software.
Because it is necessary to drill wells underground, sometimes when the building volume ratio is large, it is afraid to drill wells under the floor, so it needs early cooperation and may not be suitable for the reconstruction of buildings.
How much is a household ground source heat pump air conditioner? Advantages and disadvantages of household ground source heat pump: energy saving 40-60%, comfortable and soft blowing. There is no gas freon leakage, one system enjoys two or three kinds, and one air conditioner heats hot water. Low maintenance cost
Disadvantages: The construction technology should be meticulous, the outdoor area should be several square meters, the garden area should be large, wells should be drilled, the initial investment is relatively high, and the later maintenance is less, so it should be cleaned regularly.
What are the advantages and disadvantages of ground source heat pump system and water source heat pump system? Water source heat pump wastes groundwater resources, and ground source heat pump has more advantages in this respect. Ground source heat pump needs to use heat medium to absorb underground geothermal resources. If the amount of heat medium is small and can't meet the requirements of the required heat, it is often necessary to drill dozens of wells and pipelines, so the water source has an advantage in capital investment!
What are the advantages and disadvantages of villa ground source heat pump air conditioning? The advantages are:
First, the villa ground source heat pump has remarkable energy-saving effect.
It uses shallow underground geothermal resources to realize efficient heating and cooling. 1998 is recognized as the most efficient and energy-saving air conditioning system by the US Environmental Protection Agency and the Department of Energy. According to the statistics of return visit, the villa ground source heat pump system designed and installed by Xinyineng has the leading energy-saving effect in the industry, with energy saving of more than 35% for refrigeration and air conditioning in summer and more than 45% for floor heating in winter.
Second, the villa ground source heat pump is healthy and environmentally friendly.
Using water as the medium to transfer cold and heat, there is no need to worry about the leakage of refrigerant in the central air conditioning of the common fluorine system, which will cause indoor air pollution and endanger health. Moreover, there is no waste gas emission like gas boilers, which is environmentally friendly and pollution-free.
Third, the villa ground source heat pump floor heating is comfortable and healthy.
Ordinary central air conditioning has poor heating effect and is uncomfortable in winter. The villa ground source heat pump can be connected to the indoor floor heating system, which has the advantages of no blowing sensation, bottom-up heating, hot feet and cold head, which conforms to the theory of TCM health preservation and protects the health of family members.
Disadvantages are:
1, the ground source heat pump drilling needs a large garden site.
2. When the villa area is less than 300 square meters, the initial investment cost is much higher than that of ordinary air-conditioning floor heating system.
3, the installation company's technology and experience requirements are relatively high.
These are all from a website called sinellon, which is very detailed. I recommend you to have a look.
Advantages and disadvantages of household ground source heat pump, how much is it to install a household ground source heat pump air conditioner?
