Ground Source Heat Pump (GSHP)--
|Soil source heat pump system is a heat exchange system made up of closed loop pipe buried underground, which is divided into horizon buried pipe and vertical buried pipe according to the pipeline embedding ways.|
|Investment for system is relatively more expensive, but it has higher operation efficiency with properties of long life service life and relevant policy support, small regional restriction.|
|Geothermal energy exchange system of underground water for heat exchange is known as underground water source heat pump system. It is divided into single well and many wells. It is mainly an open system. Its investment is low. It has high efficiency but policy and geographical restrictions.|
Many kinds and specifications of the pipes
The division level of raw materials is made by long-term hydrostatic strength, resistance to slow crack growth and fast cracking resistance properties. Polyethylene pipes are divided into PE80, PE100 and PE100-RC according to the grade of raw materials.
Heat resistant polyethylene (PE-RT) is a kind of non-crosslinked polyethylene which can be used for hot water pipe and in 70 ℃ hot water for long-term. It remains the good flexibility and inertia of PE, and at the same time it has good resistance to the low temperature (-20 C), superior performance, good impact resistance, better pressure resistance, non-toxic, tasteless, non- polluting, environment friendly and recyclable. PE-RT pipe can be connected by hot melt method, which makes it convenient for installation and maintenance. PE-RT is applied to constructive hot and cold water conveying, community heating pipe network system , solar energy special pipe, building heating system and the low-temperature floor heating system.

for indoor end pipeline system
|Polybutylene (PB) cold / hot water pipeline|
Polybutylene (PB) is a linear molecular structure of the semi crystalline thermoplastic polyolefin thermoplastic, with the characteristics of excellent resistance to high temperature and aging in the long term, which makes it is one of the world's top chemical materials. PB pipe has good resistance to high temperature creep and can be maintained at high temperature, which makes it possible to be used for long term at 80 ℃. PB pipe is light and has excellent flexibility. Therefore, it has been widely used in many countries in the world, which makes it has a good reputation of "plastic gold". PB is widely used in the hot and cold water piping system, heating system, central air conditioning system in our daily life.Production standard :GB/T19473.2-2004.
Polybutylene random copolymer (PB-R) floor heating pipeline
Basel company successfully developed the new materials with the random copolymerization technology. PB-R509 is a new member of the polybutylene family, and is the best choice for the ground radiation heating.PB-R is mainly used in the ground radiation heating system, snow removal , gardening, and other pipeline application field.Production standard:CJ/T372-2011.
Heat resistant polyethylene (PE-RT) is a kind of non-crosslinked polyethylene which can be used for hot water pipe and in 70 ℃ hot water for long-term. It remains the good flexibility and inertia of PE, and at the same time it has good resistance to the low temperature (-40 C), good impact resistance, better pressure resistance.
Polypropylene random copolymer (PP-R) cold / hot water pipe
PP-R, which is also called the polypropylene type Ⅲ, is the new plastic pipe material developed in the early 90s last century in Europe. It uses gas phase copolymerization process to enable about 5% of the PE monomer to no rules copolymerization in the molecular chains of PP and, in addition to the high strength, good temperature resistance, excellent resistance to chemical and the advantages of excellent corrosion resistance of the polypropylene material, it improves the anti-impact performance, increases flexibility and improves the processing performance. Compared with the steel pipe and copper pipe, PP-R has the advantages of sanitation, light weight, corrosion resistance, small resistance, heat insulation and heat preservation, convenient connection and reliable material recycling, etc. The service life of PP-R can reach more than 50 years.
