Special heat pump compressor: open Shanghai Hitachi nine 0 of the future

Wei Deqing always help spokesman said that the current energy and environment is the serious challenges facing the world, the rising popularity of home appliance products bring the electric energy of consumption, as the necessities of life, the traditional water heater large energy consumption, high cost, serious pollution, the solar water heater and is conditioned by meteorological conditions, the air source heat pump is one of the world's most advanced energy products, energy saving, low pollution, minimum restricted conditions, both at home and abroad in recent years has maintained a rapid growth.

Due to the use of common air conditioning compressor, short product life, the motor is easy to burn out, using the environment is limited has been plagued by problems such as air source heat pump water heater industry, Shanghai Hitachi keenly capture the market opportunity, and in 2007 began work on the research of heat pump water heater dedicated compressor, deepening the market and customer on the line, to the more mature places such as Japan and Europe and the United States, the running characteristics of heat pump water heater, compressor and system matching of in-depth study, after three years of study and practice. Pioneered heat pump water heater dedicated compressor: xpowertm farce to 4.

New the early stages of the product market development difficulty is conceivable, but Shanghai Hitachi through the untiring efforts of the top-down, can this year farce 4 xpower special heat pump water heater has gradually won customer recognition. Ariston, Smith hangzhou, ningbo, Shanghai etc. Multiple vendors are now batch purchase Shanghai Hitachi special heat pump compressor, there are dozens of customers are matching or prepare bulk purchasing.

Farce to 4 xpower features: 4 times 4 times life, energy efficiency and efficient in four seasons

Heat pump water heater needs making hot water all the year round, it is necessary to meet the winter high pressure ratio (condensation temperature/evaporation temperature) and high load operation in summer. Shanghai Hitachi will be located in the water temperature of 55 ℃ above, because the water temperature reaches the national drainage standard temperature, can meet the requirements of kill legionella, and high temperature can make the tank miniaturization, reduce the installation space.

Whether it is necessary to use special heat pump compressor?

LeGong - minister for 55 ℃ temperature provides several technical schemes comparison:

Serial number

Technical solution

Plan to confirm

Plan 1

Common air conditioning compressor

Low temperature and high temperature load under the condition of motor coil temperature is beyond the scope permitted, burning motor, pump body force without checking, parts strength beyond range, bearing load increase, the abnormal abrasion, the motor features does not match with the pump body load, an exception occurs blocked.

Scheme 2

The injection compressor

Although it can decrease the temperature of exhaust, winter conditions can't guarantee anything, at the bottom of the compressor is too hot insufficient oil concentration will lead to the compressor pump body abrasion.

Plan 3

Common air conditioning compressor + electric heating

Can effect comparing is too low, national energy efficiency standards will be introduced, standard after such products will not have room for survival.

Plan 4

Mixed refrigerant

Purpose to reduce exhaust temperature use "mixed" refrigerant can cause instability and the performance of compressor locked-rotor, stall, damage to the parts, and other issues (Shanghai Hitachi special statement, brand to use rules of refrigerant, compressor can't give corresponding quality assurance).

Plan 5

Industrial compressor

Can't guarantee the winter high pressure than the operation of the case.

6

A dedicated compressor

Suitable for heat pump water heater running mode, all sorts of measures to ensure the heat pump compressor design life more than a decade, ambient temperature of 15 ℃ below zero performs the water temperature of 55 ℃.

By comparing the above six schemes, obviously choose special compressor is heat pump water heater of choice! To 4 xpower, namely 4 times 4 times life, energy efficiency and efficient in four seasons. With high water temperature, operation is stable and reliable, good environment is broad, long life and other characteristics.

Sights in the long run special pressure machine price is not high

From galanz, yangzi, Finland, Germany, Nick, ariston, chigo, hangzhou, ningbo, kt, Smith, kt, DE huake, jinjiang hundred waves, Europe etc more than ten heat pump more than 20 famous manufacturer marketing, technology and procurement management. In the second half of their meeting with the director of Liu Xiaodong, Wei Deqing always help, LeGong wins, business service JiChengChang ministers is special heat pump water heater products such as performance, application technology and marketing warmly on the hot issues such as communication and discussion. Customers the most concern or heat pump water heater dedicated compressor product prices, "compared to air conditioning compressor, heat pump water heater dedicated compressor market capacity is still very low, how to promote the market, please?" , "heat pump water heater and electric, gas than the purchase price is high, if use the special compressor, price difference is bigger, the future special heat pump compressor on price any long-term plans?" Although asked in different ways, but at one place.

For these problems, Shanghai Hitachi several leaders have expressed their views, and they said, now the domestic heat pump water heater manufacturer of hundreds of thousands of enterprises, good and evil people mixed up, like air conditioning enterprises more than a decade ago, "when we compressed factory money is all too late", but live to now has more than a dozen, look back only those who pay attention to product quality and technology manufacturers, to form a strong brand and survival; In addition from the perspective of consumer is very difficult to accept the electric equipment product that the quality is not reliable, even if broken can also let a person very unpleasant experience of maintenance, everyone can empathy, repair and replacement parts is a big spending, two ordinary compressor price is much higher than a dedicated compressor, and also easy to cause loss of other components, so buy a quality reliable heat pump water heater is not economic, still can let enterprise self-destruct brand! Shanghai Hitachi hope industries and companies to be able to take a more long-term, focusing on sustainable development. Now use a dedicated compressor price although higher heat pump water heater, but with a higher water temperature and product reliability, so consumers can accept. As markets mature, comprehensive cost will reduce gradually.

Hangzhou communion meeting after ningbo formulated

After the communion meeting and the early stage of our special application of R417A environmental protection refrigerant compressor configuration, we are more profoundly aware of special heat pump compressor not wrong choice, although compared with other compressor price is high, but standing in customer's point of view, it compared with other compressor brings to the customer is in the interests of the many times. So we insist to use the Hitachi special heat pump compressor with high price. Hangzhou and choose special compression, ningbo on heat pump water heater to choose other parts of the net is the best quality, the most appropriate.
