Development of the Heat Pump Industry in China
Marketing of heat pump technology in China has been for almost 10 years, and it only makes 10 billion market shares. Heat pump industry with 10 years only made 10 billion market shares, so its market share still have a lot of room for improvement. The heat pump industry is the rise of new industries in the country before and after 2000. HVAC consulting "according to the media in the HVAC industry, from the year 1999 to 2002, is the demonstration phase of the heat pump market; from 2003 to 2005, the market share of heat pump technology is a yearly basis, many appliance manufacturers timely follow up, the heat pump manufacturer and vendors gradually increased throughout the industry entered a rapid growth; since 2006, due to the "11th Five-Year Plan" put forward the goal of 20% energy saving, improve the attention of the whole society of energy-saving technologies and energy-saving products, the mass of the heat pump technology is recognized and known, and marketing with a leap, and the solar heat pump also began to a rapid development.
Applications Range of Heat Pumps
Heat pump products in the best position to play its energy saving and environmental protection and economic efficiency requires both cooling and heating. Any kind of separate cooling or heating needs are not economic, and therefore it is in the south of the Yangtze River, especially in Guangdong and Guangxi the application is not much. With increasing comfort requirements are gradually extended the application of heat pump products geographical regions south of the Yangtze River, the market is constantly open. At the same time, the front of the heat pump products mostly for residential and commercial (building use), and has gradually expanded to the field of industrial applications. Air source heat pump cannot be used in cold places, the original only in temperatures above -5℃ After technical improvements, some air-source heat pumps have been in ultra-low temperature -20 ℃ under the conditions used. Such as sewage source heat pump and sea water source heat pump heat pump system, due to the more complex components of the sewage and seawater directly take advantage of possible corrosion unit, it needs further study.
Heat Pump Technology
The heat pump technology has matured in terms of reliability, the major technological breakthroughs and limitations are centralized at applications. The public awareness of energy conservation is to be improved. The principle of heat pump technology is the physics of the classic cycle - reverse Carnot cycle, the truth - "anti-extracting energy" is not difficult to understand, but how to control the energy extraction process, enabling it to be used for human beings, but generations of scientists developed after more than 100 years of research before. Therefore, the control technology is a core technology of heat pumps, and it must be stable and reliable.
