Ground source heat pump air conditioning in this era of environmental protection as the main line of the market is undoubtedly very vast, but, as a new energy air conditioning, because the production process is not exactly the same, its installation process is also different. Consumers in the purchase of air conditioning, will put the environmental protection in the foreground, but, ground source heat pump air conditioning in the end how to install is standardized correct? Xiaobian next take you to understand the installation process and standards of ground source heat pump air conditioning, better help you correctly install ground source heat pump air conditioning, with peace of mind good air conditioning.
Ground source heat pump air conditioning is the use of energy-saving and environmentally friendly ground source heat pump system, its cooling and heating source using the installation of flexible, easy to control buried pipe soil source heat pump system, also known as soil coupled heat pump system. Specifically, it adopts the buried pipe method of vertical burial, using water as the carrier of cold and heat, and the water circulates between the heat exchanger pipe buried in the soil and the heat pump unit to realize the heat exchange between the unit and the earth soil.
One, drilling - drilling is also known as ground source heat pump drilling is the first process of ground source heat pump underground buried pipe. Before drilling should understand the buried pipe site has underground pipelines, underground structures and their exact location, pay attention to avoid, so as not to cause damage; the total length of the borehole according to the size of the area of the building, the amount of refrigeration required to determine the accurate calculations before drilling; drilling to ensure that the vertical drill rod to ensure the parallelism of each vertical holes, to prevent tampering with the holes.
Two, vertical down the pipe - down the pipe is one of the keys to the project, down the pipe must ensure that the depth of the pipe. There is a lot of water in the hole after drilling, due to the buoyancy effect of the water, it will cause some difficulties to release the pipe, and because the water contains a lot of sediment, sediment deposition will reduce the effective depth of the hole. For this reason, after each drilling hole, the U-shaped pipe should be put into in time and fixed measures should be taken to prevent floating.
Three, horizontal pipe laying, pipe coupling - horizontal pipe laying before the bottom of the trench has been excavated to lay fine sand equivalent to the thickness of the diameter of the pipe, the installation of the pipe should not be broken, kinked, there shall be no stones in the sand, the turn should be smooth, and have fixed measures. Then according to the drawings of the requirements of each sub-area of the pipeline connection into a system, and were led to the machine room host installation location, pipe heat fusion or electrofusion connection must be in accordance with the manufacturer's construction specifications standards.
Four,? Backfill - backfill including vertical downpipe and horizontal pipe laying two parts, regardless of the kind of backfill before the pressure test must be carried out to ensure that there is no leakage. Vertical down the pipe backfill vertical hole grouting material should be used bentonite and yarn mixed slurry or special materials, can also be used in the drilling process of mud sediment, to ensure that the drilling grout is dense, no cavity, otherwise it will reduce the effect of heat transfer, affecting the quality of the project; horizontal laying of the pipe backfill soil should be fine, loose, uniform and does not contain stones and clods of soil, backfill compaction process should be uniform, and shall not make the pipe overhead.
V. Room and end? Outdoor part of the installation is completed after the installation of the indoor part of the installation, the indoor part of the installation, including the host and indoor air conditioning end, heating end of the installation, the installation of the host, to carefully check the arrival of the equipment specifications, models and configuration program in line with the actual situation at the site to determine the installation location, and then installed.
Ground source heat pump installation is a systematic project, compared to ordinary central air conditioning, its complexity its and the difficulty is much higher. If you are unable to complete the installation process yourself, you should hire a professional installer to ensure that the installation is standardized and correct. If you install it yourself, please follow the above installation steps and standards strictly, and remember not to confuse it with the installation process of ordinary air conditioners. Ground source heat pump air conditioning installation process and its installation standards must be borne in mind, only in this way, consumers can use the ground source heat pump air conditioning, so that it better benefit your life.
