Ground source heat pump advantages and disadvantages which?

The ground-source heat pump uses the tremendous thermal storage and storage capacity of the underground soil. In winter, the heat can be transferred from underground soil to the interior of the building. In the summer, the underground cold is transferred to the interior of the building. The difference is mainly reflected in the temperature. The advantages of ground source heat pumps are mainly reflected in good stability, long life and renewable. The disadvantages of ground source heat pump are mainly high initial investment, the system is more complicated, and the installation is more difficult. Ground source heat pump advantages and disadvantages which? The advantages of ground source heat pump 1, good stability: This ground temperature can be more constant temperature characteristics, making the heat pump will not be affected by the external climate, the group run more reliable and stable, there will be no ordinary air-conditioning heating, or even not Heating problem. 2, energy-efficient: ground source heat pump system uses a constant underground energy, supplemented by electricity, energy efficient. 3, long life: Ground source heat pump system is very reliable and durable, and its mechanical movement of parts is very small, all parts are not buried in the ground is installed in the room, the general outdoor heat exchange part of the life of 50 years, ground heat pump unit Life expectancy is 25 years. 4, a multi-purpose machine: ground source heat pump system can be heating, air conditioning and cooling, but also provide hot water, a multi-purpose machine, a system can replace the original heating boilers, refrigeration and air conditioning and hot water heating three sets of devices Or system, one-stop, efficient and convenient. 5, environmental renewable: ground source heat pump operation without any pollution, can be built in residential areas, in heating, no combustion, no smoke, no waste. Ground source heat pump shortcomings: 1, the initial investment of ground source heat pump is relatively high: a small home ground source heat pump system initially invested more than ten million, large commercial ground source heat pump cost is higher. 2, ground source heat pump system is complex, the installation is difficult: ground source heat pump on the design, construction, construction site management requirements are high, require professional and technical personnel involved. Ground source heat pump is one of the most emerging central air conditioning technology, its advantages and disadvantages coexist, good stability, a multi-purpose machine, environmental protection, energy saving and long service life so that it has been favored by many people, but in addition to investment, installation Complex and other shortcomings are also its practical application of the problem can not be avoided. Ground source heat pump for high technology, installation requirements are strict. But the prospects for such products is still worth the wait.

Double Cylinders are required with keys to open for coming in or out. Functionally divided into: 1) Management - Engineering key cylinder and Master key cylinders. Engineering key cylinders are being used during the project is under process. When the project is on the way, use the engineering key and When the project is finished, just use the own keys of the cylinders of themsevles.
2) Master key cylinders means that, one key can manage numbers of cylinders. From the secure function, it can be having Anti Drill, Anti Pick, Anti Pull cylinder, which are the basic functions.
Material: Brass, Zinc,etc
