Why Choose VRF HVAC Technology for your new Air Conditioning

Variable refrigerant flow air conditioners (VRF) or variable refrigerant volumes (VRV) are highly energy efficient air conditioners for precise temperature control in commercial buildings. More often, rooms or areas in a building have to work at different temperatures. The cooling and heating requirements of these rooms inevitably change throughout the day, in large part due to changes in occupancy, heat-emitting office equipment and lighting, changes in outside temperatures and, in particular, the position of the sun. This combined effect of internal and external influences often means that some parts of the building must be cooled while other areas must be heated at the same time to maintain a constant and comfortable indoor climate.



A well-designed VRF/VRV system typically serves areas that are known to have opposing heating and cooling loads and can therefore redistribute excess heat from areas requiring cooling to areas requiring heating. The VRF/VRV heat recovery system offers the highest energy efficiency and achieves SCOP/SIER above 5.0.

In its simplest form, a single outdoor unit VRF/VRV supplies multiple indoor units connected to it by a copper piping system containing refrigerant. The VRF/VRV technology achieves extremely high efficiency by converting refrigerant flow into the indoor unit based on the exact requirements of each zone. This allows precise temperature control and thus the comfort is divided into zones.

VRF/VRV air conditioners also benefit from the flexibility and modularity of the design. Multiple outdoor units can be linked together to increase the total system capacity and thereby increase the possibility of heat recovery. Indoor units are available in a variety of types and sizes, making them suitable for most applications. These systems can also be designed to minimize or even eliminate the need for air ducts, making them less expensive to implement and easier to install in tight spaces.

Complex controls allow the system to be optimized and give users complete control over their local environment without affecting other areas of the same system. These controls can also be easily integrated into the BMS building management system if required.

Main advantages of AC VRF/VRV:

·       Very energy efficient

·       Precise temperature control

·       Simultaneous heating and cooling

·       Heat recovery

·       Zoning convenience

·       Flexible and modular design

·       Easier to install

·       Sophisticated and easy-to-use controls

These are some of the benefits of choosing VRF/VRV technology for your next air conditioner. If you are looking to an air conditioner VRF or VRV, then you consider buying from Hitachi Aircon, which offers the most advanced and energy-efficient air conditioners.

Ultimate AC Buying Guide: How to Choose the Air Conditioner

Image
Rising temperatures in India have made air conditioning (AC) more or less a necessity for every household. However, choosing the wrong air conditioner for your home can lead to high electricity bills or regret buying an air conditioner that is not very good to keep your room cool. It is very important to have the correct information before you go to the store and buy. This buying guide is designed to help you determine the factors you need to consider in order to buy the right air conditioner to avoid the summer heat. How do you choose the most energy efficient air conditioner based on your needs? One of the main reasons some people may choose not to buy an air conditioner is the cost of ownership. Air conditioning efficiency was previously known as EER (Energy Efficiency Factor), but as temperatures in India vary from season to season, a new standard has been introduced - ISEER (Indian Seasonal Energy Efficiency Factor). It is the ratio of the cooling capacity of the air conditioning

Important Guidelines for Installation of Split AC

Image
Installing an air conditioner is an important task. For this reason, it is best done by professionals who are trained to do so. Good installation of  i ndoor split air conditioner is important not only for the longevity of your air conditioner, but also for good performance. A properly installed air conditioning system ensures proper cooling and also increases service life. It also helps to perform service and maintenance under warranty. While a professional will install an air conditioner, it is important for you, the consumer, to understand some of the important aspects of installing a split air conditioner. 1. Installation site Determine the exact location of the indoor and outdoor units. You don't want to install the air conditioner where the cooling is inefficient or so cold that you feel like you're at the North Pole. 2. Wall thickness Make sure the wall that holds the AC indoor unit is strong enough. It should withstand the vibration of the device. 3. Dista
