I'm considering buying a new split unit air conditioner for myActually, this will be for a room that is planned as aI'm located in Bombay, India, now referred to as One question I am facing is whether an inverter or a regular air-conditioner is a better choice. I was told by one dealer that inverter air-conditioners can be problematic choices, especially in humid climates near the sea. This pretty much describes my home, which is less than a kilometer from the shores of the Arabian Sea. this out on the web a bit. While I did not find much information, I did find some supporting evidence. Daikin Inverter AC Unit Fail - Moisture / Salts Damage to PCB. Basically, the issue is that an inverter is rather more complex electronically than a regular air-conditioner, because it is doingThis manifests itself in more complex circuitry and more circuitThese are referred to here as PCBs (presumably Printed Circuit boards), Given salty damp air, these circuits corrode over time.

in an inverter, there are more of these circuits. cost more to repair. The bottom line, then, is that if you are near the sea, don't use an inverter, because you will have more frequent breakdowns and higher maintenance costs. What is puzzling is, if this is true, why isn't there more discussion about this on the net? And other dealers I asked disagreed about this. I'll also mention parenthetically that I have tentatively settled onwindow ac unit 15000 btu Mitsubishi Heavy Industries machines. sistem air handling unitThis is not directly relevant towindow ac units sideways this question, so I'll leave out the details of that - it is specific to my specific buying environment. One dealer I talked to said the

PCBs in MHI machines were silicone-coated, so it wasn't an issue. I'm in Michigan and we get harsh winters and salt our roads. Salty roads and ice get on our cars, and this combination is really harsh on our metal parts of our cars. Salty humidity is also very harsh on any metal parts, even galvanized steel. Now galvanized steel in the US has improved in the past 20 years, but it is not impervious to salt water. That said, you will need to have all important parts coated some how to prevent corrosion as salty humidity is super corrosive. There is a service in the US that coats cell phones with a nano coating. They don't even take apart the cell phone. After the phone is processed you can drop it in a pool and it will still work. The phone is guaranteed for life vs moisture and water. If the AC company has this service available they can coat their PCB boards and that should help a lot. Or they can use another coating on the PCB boards. The coating cannot conduct electricity or it will short out the boards.

Electrical appliances, be it air conditioner, television or some other; have become an important part of our lifestyles. Summers without air conditioner seem very difficult to even imagine and that's when we come in the picture.

Every home application differs when it comes to using AC system.Daikin and Mitsubishi are both high performing systems. I am using Daikin and pretty satisfied with the air conditioning and after sale service. However, I consulted Air & Water experts before buying Daikin.Also, must check and compare the specifications of the products.

Hope it will help you.Written Written Mitsubishi electric, Ogeneral & Trane are the best in class of split ac. I have personally experienced their cooling. Always buy ac with highest COOLING CAPACITY in same Tonnage.

These systems are no longer as rare as they were in the past and are now getting the attention they deserve together with increased market share. The most prominent manufactures of such Air-Conditioning systems are Japanese with companies like: Daikin, Mitsubishi Electric, Mitsubishi Heavy VRF, Fujitsu, Hitachi, Sanyo / Panasonic and Toshiba.

Daikin for instance, was the first company to introduce this technology, called ‘VRV’ (Variable Refrigerant Volume). All other HVAC manufacturers followed Daikin with their own version of the technology called ‘VRF’ (Variable Refrigerant Flow). Additional players outside of Japan producing VRF air- Conditioning systems are Koreans with companies like: LG and Samsung with other large players from China as Gree, Midea and Haier. VRV / VRF Air-Conditioning systems have been distributed and installed all over the globe for about 35 years. At the start their market penetration was slow but has increased dramatically in recent years once individuals and companies began to understand the significant energy savings of 30% and even higher, these systems may provide. Countries in Europe, Far- East and South East Asia, with China leading by far, have been world leaders on the number of systems installed and increasing market share compared to those in the U.S. The U.S. started embracing the technology within the last 5 - 7 years with a significant growth in usage every year.

Realizing the benefits of these systems, leading Air-Conditioning companies in N.A have started to use the technology by forming alliances with existing manufacturers from Japan and Korea. For instance, Johnson Control with Sanyo / Panasonic and Hitachi; Carrier has formed a joint operation in the States with Toshiba naming it: Carrier-Toshiba and Trane allied with Samsung to introduce their OEM VRF version. As the U.S. started its economic recovery following the crisis that hit the U.S. in 2008, it is now possible to notice the growing penetration of VRV/VRF Systems in the U.S market; a fact that was firmly confirmed by Will Scott a Sales Manager for Mitsubishi in the U.S. already in 2010: " VRF shipments have continued to enjoy double-digit growth throughout the economic downturn. And as more engineers and contractors have successfully applied VRF across a wider spectrum of market segments, we expect their comfort level with VRF to translate into accelerated growth as we begin our economic recovery,” (achrnews: Nov 22 2010)

VRV / VRF / Split Air-Conditioning control and Monitoring VRV and VRF Air-Conditioning systems along with Splits from the same manufacturers are more sophisticated in their control systems incorporating built-in communication means, unlike the traditional Central and Split Air- Conditioning systems that typically incorporate only a basic form of on/off control logic. The control and monitoring of VRV / VRF and their Split Air - Conditioning Systems is done with solutions provided by the HVAC companies who offer Central Controllers, Communication Gateway / Converters and thermostats to control and monitor outdoor / indoor units on issues like: On /Off Control, Cool, Heat, Fan, Dry Mode selection, Temperature set, Fan speed, Swing, Filter reset, Group operation, (all On all Off), Failure Codes etc.' Communication protocols of VRV / VRF Air-Conditioning are not published or disclosed by the manufacturers, and each maintains its own unique protocol. This situation limits the supply of control solutions only to those offered by the manufacturers preventing third party suppliers from competing and offer solutions with better design, functionality and pricing to accommodate today's modern house design and advanced communication means.

Integration of Control4, Crestron, Savant etc’ Controlers with VRV / VRF and Split Air-Conditioning Systems                                                                               Not an Easy Task! The world market for Smart Home Systems, also known as Home Automation, has grown dramatically in recent years to reach several billion dollars a year. H/W Systems and applications are designed and built to satisfy the increasing demands of the modern house in areas like electricity, lighting, shades, security (cameras, gates), climate, entertainment and more. Manufacturers and suppliers in Home Automation are divided according to their expertise where some focus and specialize in a particular area; others provide complete H/W and S/W solutions for control and monitoring of the entire home. Prominent players in this market are Crestron, Control4, Lutron, Vantage, Savant, AMX, RTI, HAI, ElAN and many others. The controller display unit, usually supplied with the Home Automation system, provides the home owner with the ability to centrally control and monitor almost every peripheral around the house without the need to abandon his couch.

This becomes even of a greater necessity when living in large luxury houses having many rooms and big distances to cover. Nevertheless, one major area that has been overlooked and not properly addressed by the home automation companies is the ability to centrally control and monitor the Air - Conditioning units especially VRV / VRF systems, thus totally ignore the increasing use of these A/C systems. In the absence of adequate control solutions, the home owner has no choice but to use the cumbersome and expensive control equipment as supplied by the HVAC companies. Integration - Not an Easy Task!
