Water source heat pump is based on water temperature as heat exchanger design and configuration of a heat pump heating and cooling device, whether it is the use of sea water or any other water, are the same, as long as it is able to achieve normal circulation without freezing normal heating Or cooling cooling, can achieve high energy (as long as the use of new technologies without error); as for the water source heat pump unit is another matter, or only the different equipment or system configuration, the selection of different sources of heat and heat pump Heating technology itself has nothing to do, the selection and utilization of water does not belong to the heat pump technology. The use of heat pumps to achieve heating heating technology has decades of history, the use of foreign countries much earlier than the domestic, or can be directly said that China's heat pump is moved from abroad, so the development is always the most foreign Advanced, which may also be the traditional concept of many domestic users, so since the history of refrigeration and air conditioning technology and equipment only foreign or imported brands are more market users choose, which may no longer be a permanent law of development. Heat pump is a high energy-saving new technology, new technology is constantly developing and perfect, and only continue to innovate and develop in order to be more advanced and more perfect. The traditional heat pump air conditioning technology can not completely replace the latest heat pump technology, in the global mutation and development of human society, the "long history" of the old product can not completely represent the new heat pump technology and new achievements; If the heat pump heating and cooling technology with different sources of water (sea water or groundwater, etc.) mixed with a beach, that as long as foreign old and mature old technology and reliable products, or the so-called special seawater source heat pump technology and products, is a wrong Concept and idea, but also will directly affect the heat pump heating and cooling new technologies and new products to promote and application. Water source heat pump device to adapt to any different quality of water as a heat exchanger (such as groundwater, seawater, urban sewage, etc.). Water source heat pump air conditioning, especially sea water source heat pump system, so far no more advanced technology and products, because both abroad and domestic are faster development in recent years, especially in Western countries The configuration of the building structure can not be compared with the situation of most buildings in China, so foreign things can not be completely copied to the domestic market and users; Domestic heat pump technology has reached the current more advanced level, relying entirely on its own innovative strength, creative research and development with independent intellectual property rights of a number of inventions and new technologies and new products continue to emerge, and the new technology to solve many historic The main task, to maximize the utilization of water, so as to achieve the purpose of saving water resources, and can effectively improve the heating heating temperature, which is the current domestic heat pump heating technology development and status quo. Such as: water source continuous heat pump air conditioning unit, is a design innovation, perfect performance, wide range of uses, change efficiency, high energy-saving large-scale water source (sea water) heat pump air conditioning unit to adapt to a variety of different temperature, Such as rivers and lakes seawater, industrial waste heat, urban sewage heat, etc.), can be directly configured to use seawater as a heat source; one-time beneficial heat recovery and conversion efficiency can reach more than 95%, save water more than 35%, reduce the comprehensive investment of 10% ; After conversion are clean source of heat and cold; suitable for a variety of building central heating heating and cooling air conditioning; also applies to different industrial and other environments. The new device can also be achieved at the same time, according to the different heating value of the output of different stages of the supply of different users, to achieve high quality heat price of scientific configuration and management; more suitable for the currently widely used in the radiant floor heating heating, Non-corrosive, more comfortable and more energy-saving; it can also be used for efficient recovery and conversion of sewage heat sources in oilfield mines or other mining areas; The technology and products are important technologies and supporting equipment which are reasonable, efficient and comprehensive utilization of heat sources with different water temperatures and other heat sources. The new technology does not cause pollution and does not affect the reuse of primary water sources. As we all know, heat pump is an energy-efficient technology and conversion device; new technologies and new products have reached or exceeded the comprehensive energy efficiency of similar technologies at home and abroad and product standards, and has a simple structure, stable performance, stand-alone power, installation and construction Simple, heating temperature is high, easy to operate and management features. Adopting the current large-scale water source (seawater) heat pump heating and cooling device in China to provide heating, cooling and cooling for all kinds of large-scale buildings, with low investment, low cost, no pollution and good management, it not only has the objective and objective economic significance of modern high-tech achievements, More long-term development of human society significance.
