How to identify qualified air source heat pump?

Air source heat pump has a very significant energy saving, environmental protection, safety and easy management features, by many schools, hotels, homes and other favored, is now widely used in schools, hotels, homes and other hot water and Heating supply system, and well received. How to identify qualified air source heat pump? And some heat pump hot water project gradually exposed in the course of a lot of problems, including the heat pump hot water unit itself, the installation of the project, the use of management, resulting in hot water supply is not Normal, excessive energy consumption, hot water costs and other consequences; a lesson, the car division, a heat pump procurement experts is actually very simple, you can, as long as the key to choose a good pump, everything is solved, heat pump products Good and bad absolutely can not escape your eyes. Select the key point of the heat pump unit 1, production license: Because air source heat pump is a technical product with strict requirements, the product you want to choose first look at whether it is issued by the State Administration of Quality Supervision, Inspection and Quarantine of the national industrial production permit (based on The number of certificates provided by manufacturers to check the authenticity of the Internet to prevent counterfeiting, the following types of certificates the same), non-certified enterprises can be regarded as illegal production, the product has not been tested by the state authority departments, quality and performance is difficult to be guaranteed, At the same time, manufacturers, distributors and consumers have to bear the relevant responsibilities, as consumers should be cautious; regard it as the first key point based on the following two points: A, the legal risk from 100% down Zero, do a non-legal risk of procurement; B, can be eliminated more than 95% of the heat pump products, only from 5% to choose what you want, effectively reduce the risk and workload, improve accuracy. 2, registered trademark certificate: According to the relevant laws and regulations of commodity circulation, heat pump as a commodity, the brand must be registered trademark of the Trademark Office to sell, to prevent some of the "three noes" manufacturers trouble; can be eliminated more than 20% of the unqualified Heat pump products to improve the reliability of the selection. 3, the performance test report: After testing the national authorities, the performance of the products meet the relevant standards is qualified, the higher the cop value detected to prove that the more energy-efficient use, good air-source heat pump than the average more than 10% , So sometimes can not be cheap at the time of purchase, a small loss, a good product will let you save more. 4, 3C certification: Heat pump hot water unit is a national compulsory certification products, must pass the China Quality Certification Center of testing and obtained by the China National Compulsory Certification (CCC certification) before sale. 5, the unit structure and weight: product weight difference caused by the three main areas: the evaporator, condensing heat exchanger and the shell; the same structure of the unit, the lighter unit has the suspense of cutting corners, material thin or short, the performance It is difficult to be guaranteed. 6, the type of compressor: Compressor is compared to the heart of the heat pump unit, its performance is very good or bad; currently commercial large heat pump unit to the United States Copeland compressor for the best, of course, to ensure that the original factory, In case some manufacturers shoddy, with the repair of the compressor. 7, electronic control technology: If the compressor is the heart of the heat pump, then the electronic control is the brain of the heat pump, an excellent electronic control board can effectively solve the complex problems of heat pump units, installation is more simple, more flexible control and reduce heat pump Glitches in the operation of the unit, the stability is guaranteed. 8, throttling technology: throttling technology is to optimize the performance of a heat pump unit a key, there are capillary throttling, thermal expansion valve throttling and electronic throttling throttling throttling technology to electronic expansion valve throttling technology For the most advanced and effective solution to heat pump frost in winter problems, access to higher energy efficiency, more stable and reliable performance. 9, the shell of the process: sleek appearance, sheet metal production well, the structure is solid and reliable is a good product standards, a product's shell technology level will reflect the positioning of their products and manufacturing concepts, the shell usually poor material, not beautiful , Not willing to spend the cost of the enterprise in the other components of the input will not be large, largely unwieldy. 10, production equipment: Only good production equipment to make a good heat pump products, at least have a professional performance testing room and test workshop, a product that has not been tested on the factory you dare? 11. System Matching Level: Whether a heat pump product can run stably under different air temperature and water temperature, the matching level of the system is the key, just like the car chassis control technology. High levels of heat pump products not only deal with the high temperature caused by the high pressure but also to solve the problem of low temperature frosting, low failure rate of the unit, the maintenance easier! This and a business technology has a great relationship. 12, the level of project installation: a good product also needs a good installation, find a professional, experienced installation team is the key to the success of a heat pump hot water project, because a good heat pump products installed in a muddle-headed project abound Yes, energy-saving projects have become energy-consuming projects, showing the importance of installation. 13, after-sales service: any product has the possibility of failure, timely and capable after-sales service is essential; the first to be timely, the second should have the ability (bad can repair, will repair, some manufacturers even own The product will not repair the broken, so troublesome), the third according to the provisions of the state warranty (mechanical and electrical products for 18 months).
