Key words: sea water source heat pump
The so-called seawater source heat pump is a heat pump heating and cooling system and device designed and configured by using seawater as a heat exchange source, which is a different configuration form of the heat pump device but only the heat exchange source of different choice. The so-called special, only for different seawater using different materials (corrosion-resistant) heat exchanger (evaporator and condenser) and so on. According to the concept of "water source heat pump" which we all know at present, "sea water source heat pump" is one of water source heat pumps. Water source heat pump is a heat pump heating and cooling systems and devices designed and configured with different water temperatures as heat exchangers. Whether it is the use of seawater or any other water source, it is the same as long as it can guarantee non-freezing when the normal circulation heat exchangers are used. Can be normal heating or cooling cooling, can achieve high energy efficiency (compared with the air source heat pump); on the heat pump unit to adapt to and use of a water source is only the problem of equipment or system configuration, the use of different water sources and Heat pump technology itself has nothing to do, the choice and utilization of water does not belong to the heat pump heating and cooling conversion areas.
Although the use of heat pump heating has been decades of history, foreigners using heat pump heating although earlier than the domestic, or can be said that China's heat pump is learned from abroad, which may also be the tradition of many domestic users Concept. Therefore, since the history of refrigeration and air-conditioning equipment, only foreign or imported brands are more marketable in China. This is an indisputable fact but it will no longer be a permanent law of development.
The heat pump is a technology and device that converts and utilizes natural thermal energy. The natural world contains infinite heat energy, especially low-temperature (low-grade) heat (such as natural temperature, water temperature, soil temperature, industrial waste water and waste heat) These heats are very close to the building's thermal energy, heat pump is a new energy-saving technology, the use of heat pump technology and conversion devices can be used for heating and heating can be used for cooling.
Heat pump heating is a new artificial heating and cooling technology, heat pump technology innovation and development is the key to breakthroughs and improve the heat transfer efficiency and increase the heating temperature and at the same time achieve high energy efficiency. The selection of heat pump units can not only recognize the import of traditional brands or the oldest products, especially large or very large heat pump units, the current domestic breakthroughs in innovative technologies, large heat pump equipment for the development and development has provided a new idea has been So that large and large heat pump unit for the development of heating and supporting production accessibility.
"Stand-alone capacity is small, the overall efficiency is not high, but also unable to reach the district heating and cooling capacity," the argument and argument and prejudice, has not meet the current domestic existing innovative technologies and products of the status quo and facts is a traditional Follow, Chong Yang, the same set of "conservative concept of development, is to influence independent innovation and technological development ideas. Seawater source heat pump heating and cooling technology and products, especially the large seawater source heat pump heating and cooling device, I think: so far no more advanced technology and products, because regardless of foreign or domestic technology and products are in recent years It has been faster development and application, so foreign things can not be completely copied to the domestic market and users;
The new technology is constantly developing and improving, especially the large-scale water source heat pump technology and products. Only by continuing to innovate and develop can we be more advanced and perfect. So far, the traditional and foreign heat pump air conditioning technology can not completely replace the latest heat pump technology, the "old" old products, the old brand can not completely represent new technologies and new achievements; the introduction of mature technology of existing foreign products Redevelopment of products in the country is the simplest and most convenient way. Products that are developed at the expense of the economy or the market and are developed under the name of imported technology are easily accepted by domestic market users. However, imports from abroad are never the most important Advanced technology and products, do not belong to independent innovation technology and products.
To create invention is Chinese nature. At present, the technology of heat pump heating and cooling has reached a more advanced level in our country, and the innovative technologies and products with completely independent intellectual property rights have been developed relying entirely on their own innovative capabilities. Moreover, new technologies have broken through and solved many historic and difficult issues. At present, we have independently developed and successfully developed large-sized and super large-scale heat pump unit for heating and cooling equipment, which has the unique features of single unit power, high water utilization rate, high heating output temperature and wide range of heat source, which can maximize water supply Utilization and improve the heating output temperature, which can achieve the purpose of saving water resources and improve heating and heating effect, which is the current domestic heat pump technology innovation and development features.
Such as: "water source continuous heat pump air conditioner" and "secondary condensing heat pump air conditioner", is a design innovation, perfect performance, wide range of uses, high efficiency, high energy-saving large-scale high-temperature "seawater source" heat pump heating The air-conditioning device is suitable for seawater heat sources (or other water sources such as rivers, lakes, seawater, industrial waste heat, urban sewage, etc.) of different temperature and different water quality, and can be directly used for heating and cooling of large area and regional central heating, Cool down
A one-time beneficial recovery and utilization of heat can reach more than 95%, saving more than 35% of water, reducing the comprehensive investment of more than 10%; after conversion are clean source of heat and cold; suitable for a variety of different buildings Centralized heating and cooling air conditioning; also applies to different industrial and other environments. At the same time, the new device can also output and supply different users according to different calorific value staging and segmenting respectively, so as to realize the scientific configuration and management of high quality and favorable price of heat source, and is more suitable for the floor radiant heating which is widely used at present;
As we all know, heat pump is a kind of energy-efficient technology and conversion device; at present, China has new technologies and new products, the overall energy efficiency has reached or exceeded the current standards of similar technologies and products, and has a simple structure, stable performance, single power , To adapt to a wide range of installation and construction simple, high temperature heating. Series of large seawater source heat pump heating and cooling device can be widely suitable for a variety of domestic and foreign seawater heat resources.
China is rich in seawater resources. Sea water source heat pump is a kind of new technique and new product of water source heat pump. It should be widely adapted to any heat source of different quality (such as groundwater, seawater, urban sewage). At present, Innovative technologies and new products for all types of large-scale buildings supporting heating and cooling cooling, low investment, low cost, pollution-free, good management, both with modern high-tech achievements of the objective and objective economic significance, but also have long-term savings Significance of social development and progress.
