May 21 - Melco Releases CO2 H/P Water Heaters with 4.9 COP

Mitsubishi Electric Corp. (Melco) commenced the successive release of 9 new models of Mitsubishi ECO CUTE natural refrigerant (CO2) heat pump water heaters ffrom June 15. They feature the industry's top COP of 4.9 (during the rated mode of operation) and also the improved versatility.
All the new models have attained the an industry?s top high COP of 4.9 (during the rated mode of operation) thanks to the adoption of an efficient rotary compressor which has been favorably incorporated well into the companys heat pump units, and the companys own high-efficiency Poki Poki (joint lap) motor with high winding density. While improving the energy efficiency, the new units have realized the industrys top-class quietness lowest operating noise level; of 38 dB for a type whosewith a tank capacity is of 370 liters. Water is efficiently heated by adopting the newly developed Twist & Spiral Gas Cooler with improved efficiency through a widened enlarged heat transfer area of ain the heat exchanger for water heating in the tank unit.
The hot water storage tank is coated with new heat insulator (EPS material), thus realizing about a 15% improvement in tank's temperature retaining performance. Since heat escapes less from the tank, the frequency of hot water reheating frequency can beis reduced.
Servicing can be made without removing the front panel. The hot water storage tank unit's piping connection is made through an external joint structure. Also, the inclusion of a small window for power source?on the lower front part of the hot water storage tank for assists in power source installation has been secured on the lower front part of the hot water storage tank. Since the piping connecting position is by about 200 mm higher than conventional models, it is easier to perform resin piping connections.

May 14 - The Vector: An Evolutionary New Compressor from Tecumseh

Tecumseh Products Company, a full line, independent global manufacturer, has developed a new series of compressor: The Vector and introduced it at AHR Expo 2001 in Atlanta, USA. The Vector Series represents a new evolution of the reciprocating compressor. The technology that's been tested, trusted, and steadily improved over the past 25 years and is now in a new form, with dramatically new specs, and a price that will significantly lower customers' applied unit cost ? particularly where they are now using scroll technology. According to Tecumseh CEO Todd Herrick, the new compressor was designed to fit most existing scroll applications. "Years ago our customers began asking us for a way to get the same kind of performance, sound, and dependability as a scroll ? for less money," Herrick explains. "That was a tough question. Because scroll technology is inherently expensive, we knew we had only one option: to design a new kind of compressor that would compete with the scroll or anything else on the market in terms of sound, size, efficiency, dependability, and quality, at a price that would lower our customers' applied cost." Jim Hammond, Director of Marketing, recalls the initial breakthrough. "Since the scroll was our main target, we made the decision to work our recip technology to fit into a scroll-type housing, and do whatever it took to make the specs. Of course it wasn't as simple as dropping a recip into a steel barrel. But that was the first step. We had to design special innovative mufflers to lower the sound level and improve the sound overall. Vibration was an enemy, of course. Significant structural changes had to be made to accommodate the round shape. Prototypes were designed, built, tested, and re-designed." Compared to a scroll there's really nothing unusual about its size, shape, or appearance. And compared to a scroll, there's nothing earthshaking about its performance, either. But that's the earthshaking thing about it. With a sound level of 73 dB and an efficiency rating of 11+/18+ EER, it does just about anything a scroll will do. The beauty is, of course, it's reciprocating technology. Even though it's a brand new product. Tecumseh has already privately shown it to a few customers in the industry, to get their reaction, and to see if they could suggest changes that might make it more appealing.

May 9 - Matsushita to Establish Sales Headquarters in Middle East

Matsushita Electric Industrial Co., Ltd., best known worldwide for its Panasonic and national brand names, recently announced that it will establish a wholly owned sales headquarters in Dubai, United Arab Emirates. The new company, Panasonic Marketing Middle East FZE (PMM), is set to begin operation on April 1, 2001, with a capital of 4 million dirhams (approx. 1 million US dollars) and total employment of 36 people. The functions of the existing Middle East Office in Dubai, which include being in charge of administrating representative offices in the Middle East region, will be absorbed by this new sales headquarters. Moreover, the existing sales company in the region, Panasonic Gulf FZE (PGF), will become a part of PMM and continue its operation of re-exporting products to neighboring countries where there are no sales agents. This will enable PMM to consolidate its marketing activities out in Japan, which include sales, order procurement, payment, collection, advertising, and customer service, will be transferred to PMM by April 2003. The establishment of PMM facilitates one of the policies expressed in Matsushita's "Value Creation 21" plan, that of transferring the functions of Corporate Overseas Management Divisions in Japan to the different regions worldwide. This will enable the Company to make faster, more immediate decisions, further cultivate the market, reduce distribution costs, and provide more timely management advice to its distributors in the region.

May 5 - Nippon Mitsubishi Oil Develops New Lubricant for HFC Compressors

The Nippon Mitsubishi Oil Corp., Tokyo, has developed Ze-GLES WR, a new series of ester-based refrigeration oils for use in refrigerating and air conditioning equipment that employ HFC refrigerants. Formulated with an innovative chemical structure in place of the conventional polyol ester (POE), ze-GLES WR has outstanding miscibility with HFC refrigerants. In durability tests conducted by several compressor manufacturers in Japan and other countries, Ze-GLES WR has been shown to perform better than conventional POE oils in terms of both wear prevention in compressors and capillary flow rate stability, a factor that affects the reliability of refrigeration systems. Ze-GLES WR's greatest advantage is that it is about 20% less expensive to manufacture than POE oils, thus helping to reduce the compressor costs. The new oil was announced at the Purdue Conference in 2000, and patent applications have been submitted for it (international publication numbers: W001/02519, etc.). The switchover from CFCs to HFCs required many improvements to refrigeration oils and systems, but switching from POE oils to Ze-GLEX WR requires no special modifications. It can be used with the same organic materials, metals, and refrigeration technologies that have been used in or proposed for conventional POE oil systems. Ze-GLES WR is now available in four viscosity grades from 10 to 20 based on the kinematic viscosity at 40^oC.
