Since 2009, China's ground source heat pump has entered a period of rapid development. Under the call of China's “Twelfth Five-Year Plan†for energy saving and emission reduction, ground source heat pumps ushered in greater opportunities for development. Analysts in the machinery industry pointed out that the promotion of ground-source heat pump technology is one of the effective ways to adjust the structure of building energy use and effectively reduce building energy consumption. Ground-source heat pump has about 55% energy saving compared with other conventional heating technologies, does not emit any waste, and is relatively environmentally friendly. As a new industry, ground-source heat pump technology also encounters problems such as construction quality, difficulty in maintenance, and difficulty of standard compatibility. Three major problems with fewer problems.
The basis for the development of ground source heat pumps is the normative standard. Therefore, the outdoor heat exchange system, the water source heat pump unit and the indoor heating and air conditioning end system involve the docking and unification of standards in various fields and disciplines such as construction, machinery, electric energy, and hydropower.
Related departments should strongly support ground source heat pump projects. However, the ground source heat pump project is a systematic project. In the implementation process, it usually needs the cooperation of different departments such as hydrogeological survey, urban municipal administration, environmental protection, machinery, electric power, and construction environment and equipment. Therefore, the construction and operation of the heat pump system is urgently needed. Conduct unified planning and management.
On the whole, the market is not standardized, and lack of market access system and scientific evaluation system is the main reason that restricts the promotion of ground source heat pump technology in China. Disregard competition and the risk of mutual thermal interference between adjacent ground source heat pump projects should be taken seriously.
According to the “Competitive Situation Research Report on China's Ground Source Heat Pump Development Trends in 2010-2013†​​published by Champ Consulting, it shows that after years of development, the “Renewable Energy Law†and the “Renewable Energy Medium and Long Term Development Plan†and other laws The laws and regulations have been promulgated one after another. Ground-source heat pumps play a prominent role in building energy efficiency and renewable energy utilization. At present, the application of ground source heat pumps is concentrated in North America, Europe and China. In the spring of renewable energy development, our country's ground source heat pump will achieve rapid development.
Maximum Load:60-10,000kg
The state of the art VR type electric chain hoist is an indispensable item used in the light-duty lifting industries across the world, where the characteristic of reliability is designed into the hoist structure, safety features incorporated into the operating system, and advanced crafting techniques introduced into the modern design.
Made for less volume, lighter weight, and more operating safety and convenience, the chain hoist has the ability to adapt to various working environment, all available at a competitive price. Different models offer choices of lifting capacities ranging between 60kg and 7500kg to suit everyday light-duty lifting work. When used in combination with manually operated trolley, hand-pushed trolley, or motor-driven trolley, the hoist can be mounted on the mono-rail traveling Crane, Jib Crane, and Gantry Crane. This provides a maximum solution to solve your material handling applications.
