Mr. Xie : hangzhou hangzhou ningbo heat energy technology co., LTD. Has long been a positive response to the national policy of energy conservation and emissions reduction. Hangzhou in 2009, ningbo company cooperate with the international well-known brand, take the lead in the heat pump hot water industry developed using special heat pump hot water compressor of air can heat pump water heater. This series of products, to solve the long-standing low temperature air to heat pump industry, suitable environmental temperature narrow range, there is no guarantee that the service life of compressor.
Using special compressor hangzhou, ningbo air can water heater service life can reach more than ten years, and further raise the temperature of hot water, hot water temperature can reach 65 ℃, better meet user demand for the temperature of hot water; The system all adopt the environmental refrigerant R417A, not destroy the atmospheric ozone layer, compared with the conventional heat pump water heater using R22 refrigerant, environmental protection is obvious. Using dynamic heating mode, can effect comparing is higher, compared to the market generally used static heating mode, energy efficiency increased by more than 15%.
The machine is running, the environment of high temperature evaporation temperature control technology, avoid the evaporation temperature is too high, reduce the compressor load, ensures reliable operation at high temperature machine.
Also USES the unique regenerative technology, when the environment temperature is low, improve the compressor suction pressure, reduce the compressor exhaust pressure, thus reduce the compression ratio of the compressor, at the same time cooperate with expansion valve throttling technology according to the change of the load automatically adjust the refrigerant circulation flow, make below 0 ℃ low temperature environment of the system not only heat and coefficient of performance (COP) increased by more than 10%, at the same time, effectively prevent compressor liquid impact damage, high temperature burning, such as lack of oil burning, ensure the unit in 15 ℃ environment can be normal and reliable operation, the applicable scope of the product from southern China to the north of the Yellow River.
HangNing air source water heater will also living hot water and floor heating combined, not only meet the needs of the domestic hot water in the winter, automatic constant temperature control of heating room temperature at the same time. And with the combination of solar control function, the automatic conversion of heat pump and solar energy heating mode, to maximize the use of solar energy.
In order to solve the user in using hot water, draining water pipe in cold water and will wait for hot water, HangNing air can water heater designed a key backwater and function of automatic return, implementation in the need to use hot water, let the water pipes filled with hot water, leading a open, hot water namely.
Hc360: a few days ago, your company and Hitachi, the development situation and special compressor in heat pump water heater is in promotion is discussed and the problems in the analysis, would you please introduce what are the harvest this exchange can be used for reference in the industry?
Mr. Xie : Honny with Hitachi is mainly for the development of heat pump water heater is discussed and analyzed, the heat pump water heater in China after years of development, have their own market, but is still in primary stage. Standardize the market, to tell people what kind of products are qualified products seem to be very important. In the process of heat pump water heater industry rapid development, some manufacturers and dealers to exaggerate the effect of heat pump water heater from the realities, are to the healthy development of the industry. In the face of such a mess, the market needs to mature technology, the strong voice to good quality products.
Industry development needs makers and parts, especially the core component manufacturers to promote, the compressor is the heart of the heat pump products, compressor technology mature and widely used, to illustrate the development of the industry to a mature stage.
From Shanghai Hitachi compressor r&d, HangNingCong machine application research on mutual cooperation, promote the progress of product technology, the special compressor, mainly in 1 HP and 1.5 HP, 2 HP, Shanghai Hitachi will further accelerate the speed of 1 HP, 3 HP in a small, 5 HP compressor development, HangNing will also take a special compressor of more products to the market.
Hc360: in recent years, heat pump water heater as hvac engineering technology of a specific energy-saving measures, in the domestic vigorously the development of the market to its acceptance? As a company how to enhance the consciousness of the masses.
Mr. Xie: Honny heat pump water heater sales object is mainly villas and apartments of consumer groups, the user for comfort living hot water: in the first place, what they need most is stable and reliable, high quality products with quality guarantee.
At present, heat pump water heater industry in the face of energy-saving, environmental protection and family comfort hot water demand trends, appear very impetuous, poor quality, poor products flooding the market, false or blindly boasting about product performance, in order to obtain short-term interests at the expense of consumers, serious damage to the healthy development of the industry.
