1: There is already a ready-made exhaust heat and air-conditioning duct in my room, can I continue to connect with the ground-source heat pump system? A: Absolutely. Technicians may make minor changes to some exhaust systems to make the best emissions performance. 2: buried heat exchanger system efficiency how? A: Buried heat exchange system using the latest high-tech products, efficient heat transfer efficiency, smooth tube wall, everything is done perfect. 3: buried underground closed loop pipeline really effective? A: The energy collected through underground pipelines is the latest technological achievement in heat pump technology development. The theoretical idea of ​​this technology originated in the 1940s. However, until recent years, the design innovation of heat pump technology and the development of underground pipe material technology have made geothermal energy-based heat pump technology the best choice for commercial applications Claim. So far, ground-source heat pump technology has become a mature technology that exists both in the economy and in technology with traditional heating and cooling technologies and is applied in reality. 4: Ground source heat pump system is how to achieve environmental protection? A: First of all, ground source heat pump system does not directly consume coal or fuel, natural gas until there is no any direct emissions; Second, the ground source heat pump will be transferred to the underground soil heat storage, from the source to eliminate the urban heat island air-conditioning system Thirdly, a highly efficient ground source heat pump system uses a very strict control system to achieve a direct correspondence between energy output and building energy demand, reducing the residual energy loss. Fourthly, an efficient ground source heat pump system with the same output The amount of useful energy, only consume 30-60% of the electrical power, efficient primary energy utilization, is the most direct cause of environmental protection of ground-source heat pump system. 5: Permafrost will affect the ground source heat pump system? A: No. With only a small portion of our outdoor pipe section passing through the permafrost layer, the tundra does not have any negative impact on system operation through our reasonable design and installation. 6: In the extreme cold weather conditions, the need for a backup heat? A: In the usual comfort air-conditioning system, no need for a backup heat source. Ground-source heat pump systems provide the heat needed for construction even under very cold weather conditions. 7: Is the cost of this technology high? A: The initial installation cost is indeed higher than the traditional system, mainly laying the underground coil, the cost is expensive in the design and installation, and you save energy costs each year will soon offset higher than the traditional system installation costs, with With the passage of time, you can recover your investment quickly as you save on energy consumption. In the meantime, the system is nearly maintenance-free and repairs, saving you money and adding value to your home. 8: ground source heat pump central air conditioning system installation difficult? A; Most systems can be easily optimized design and installation, in the transformation project which can better reflect the real energy-saving and environmental effects. Ground source heat pump central air conditioning system and the end part of the traditional central air conditioning system is no big difference, we can also choose the fan coil plus fresh air or the whole air system, you can also use a small water ring arrangement and ground source heat pump system. 9: Will the system be affected when the pipe temperature is below zero? A: No. Antifreeze liquid in the pipe can still work normally at -20 ℃. 10: What is the real villa central air conditioning? A; The real home central air conditioning (residential central air conditioning) is a miniaturized central air conditioning system. The cooling / heating principle and structure of large central air conditioning with the same, from a host of cooling / heating, through the air duct or hot and cold water pipes connected to the multiple end of the air outlet, the cold and warm to different regions to achieve Indoor air conditioning purposes. Currently on the market the popular VRV (more than one trailer) "central air conditioning," is not the real central air conditioning, is the home split air conditioning, just put all the outside machine in an outer case only, so it's the machine Much larger than small split air conditioners. 11, ground source heat pump central air conditioning and general air conditioning comparison A. ground source heat pump central air conditioning: no outdoor unit, without defrosting, operating costs (mainly from the soil energy) is half the normal air conditioning. 12, ground source heat pump is a mature technology? A: Ground source heat pump technology originated in 1927 in Switzerland, a patent, has nearly a hundred years of history, is a very mature technology. This technology has been rapidly developed and widely used in the United States, Canada and some Europe. In the United States, for example, 400,000 units have been installed by 1997 and have been steadily growing at 10% annually. In Central and Northern Europe, France, Switzerland, Sweden, Austria, Denmark and other countries, in the shallow geothermal resource utilization (buried pipe way) is an international leader. Ground source heat pump central air conditioning basically universal. In an increasingly energy-intensive China, one of the major elements of the "Sino-U.S. Energy Efficiency and Renewable Cooperation Agreement" signed in November 1997 is "ground-source heat pump," a move that has promoted China's " Heat pump "technology promotion and application, the market is increasingly active. 13: Ground source heat pump central air conditioning will use groundwater? A: Do not use groundwater. The system underground pipeline is closed, inside the water and soil heat exchange, rather than direct extraction of groundwater. 14: ground source heat pump central air conditioning will affect the formation stability? A: No. The system only needs to drill a probe hole with a diameter of about 12 centimeters in the ground. After the hole is laid, a closed pipe will be immediately placed. 15: ground source heat pump central air conditioning need to apply for approval? A: No need. The use of groundwater is the need for relevant departments to apply for approval. Ground source heat pump system is not groundwater, is government support.
