An air conditioner is a great way to keep you and your family cool and relaxed during the summer. Buying an air conditioner, however, can be overwhelming. There are so many different types, models, and features, it can be difficult to know how to choose the one that’s right for you. Before settling on a unit, be sure to consider the space you need to cool and any optional features you may want. Once you do this, you’ll be able to find a unit perfectly suited for your cooling needs.

If there’s no wall or door separating the space you want to cool from an adjoining room, add the area of the adjoining room to your calculation because the air conditioner will have to cool that space as well.

An air conditioner with a cooling capacity of 5,000 BTUs, for example, can cool rooms that are between 100–150 square feet (9.3–13.9 m 2 ) in area. You’ll need an air conditioner with a cooling capacity of 6,000 BTUs to cool a room that’s 150–250 square feet (14–23 m 2 ) in area. For a comprehensive guide to what BTU rating most closely matches the size of your room, visit https://www. energystar. gov/products/heating_cooling/air_conditioning_room? qt-consumers_product_tab=3#qt-consumers_product_tab.

Buy a unit with 10 percent less capacity if the room you’ll be cooling is heavily shaded. Add another 4,000 BTU if you’ll be using the air conditioner to cool your kitchen. If more than 2 people will be regularly spending time in the room, increase the capacity of the air conditioner you buy by 600 BTUs per person.

Install window air conditioners in your window or in a designated space designed for a window air conditioner in your wall. Measure your window before selecting a window air conditioner. Window A/C units come in a variety of sizes. Measure the height and the width of your window and make sure these dimensions are slightly larger than the A/C unit you purchase. The height, width, and depth of an A/C unit will be printed on its box. [5] X Trustworthy Source Energy Star Program run by the U. S. Environmental Protection Agency and Department of Energy focused on educating consumers about energy efficiency Go to source

These units use more energy than comparably sized window units and aren’t as efficient at cooling. They are more convenient, however, because they are portable. Portable air conditioners are typically more expensive than window units, ranging in price from $300 — $700. Portable units also tend to be noisier than window units. You’ll need to place the portable unit near a window so that it can vent hot air through its hose to the outside.

This type of air conditioning is known as a «split» system because it is split between an inside unit and an outside unit. It is called «ductless» because it does not require the installation of any air ducts in your home. Instead, a small hose runs through your wall and connects the inside unit to the outside one. The inside unit is typically mounted high up on a wall near the ceiling and looks like a thin, long white box. Split ductless units are difficult to install, so you may want to call a professional to handle the installation.

On top of this, you’ll also have to spend money on a pre-installation evaluation of your home, any necessary modification or installation of ductwork, and the actual installation of the unit.

Call or visit a local trade organization for a list of qualified evaluators.

Ask potential contractors for a list of customer references who can testify to the quality of their work. Ask contractors for price estimates for the installation. Be sure to receive a written, itemized list of the price estimate before the contractor starts the installation. Try to schedule the installation of your central air system during the spring or fall. Since these periods are the off-seasons for HVAC contractors, you may be able to find a lower price.

If affordability is what’s most important to you, choose a simple model with mechanical controls and no LED display.

If you have an A/C unit with adjustable vents, you can change the direction of the A/C’s airflow both horizontally and vertically.

If you purchase a Wi-Fi-enabled A/C unit, you’ll be able to adjust settings on your A/C unit with an app on your smartphone or through a voice-activated smart device.

You can also use a home smart device to control a Wi-Fi-connected A/C unit.

Turn on any fans you have in your home and drink plenty of cool water. Open your windows early in the morning and after sunset. Take a cool shower before bed time and turn the dehumidifier on if you have one.

If you’re buying an A/C unit online, make sure you fully understand the online retailer’s return policy before making a purchase online, just in case you’re not 100 percent satisfied with your new unit.

Is There a Difference Between AC and HVAC

Is There a Difference Between AC and HVAC?

If you’ve spent any time researching air conditioners, chance are you saw the terms “AC” and “HVAC” thrown around. So, what does “HVAC” stand for? And is there really a difference between the two?

Put simply, “AC” stands for air conditioning (no-brainer, right?), while “HVAC” stands for heating, ventilation and air conditioning. Although the acronyms differ slightly, they’re ultimately one in the same and are often used interchangeably amongst industry professionals. While AC and HVAC are essentially the same, there are numerous types of heating and cooling products out there. Below is a quick rundown of the various AC and HVAC products offered:

What are my AC Options?

While the differences between AC and HVAC have been demystified, the two acronyms encompass an extensive list of heating and cooling products. Here are a few of the AC/HVAC mainstays on the market today:

Central Air Conditioning: Central air conditioning systems tend to be the most popular choice for heating and cooling. These HVAC systems work by combining an outdoor unit, indoor unit and a series of ducts to disperse cool and conditioned air evenly throughout the rooms of a home or business. Central AC touts lots of benefits like consistent cooling and quietness.

Split/Ductless Systems: These systems are similar to central air conditioning systems, just without the ductwork. Although these units are small, they can cool large spaces, unlike window units.

Window Units: Window units are typically used to cool a single room since they have limited cooling power. Window units essentially combine all parts of a central AC in a single, window-sized box. Although window units can provide comfort, they can be loud since they are housed indoors.

Japanese Giant Mitsubishi Heavy Industries Goes Into Central Air Conditioners for Home Use

Japanese Giant Mitsubishi Heavy Industries Goes Into Central Air Conditioners for Home Use

In recent years, it’s probably difficult for people to choose between central air conditioners and split air conditioners for home use. In fact the time that central air conditioners are used for home refurbishing is not long yet.

To many people, central air conditioner is an integrated indoor temperature control solution. Compared with the traditional split air conditioner, it has higher efficiency, lower energy consumption, and at the same time, it can save indoor space and maintain the integrity of the interior decoration.

Regarding its installation, central air conditioner is installed in hidden places in the room, mostly attached to the ceiling, which is much more beautiful than cabinet type or split hanging type air conditioner.

However, central air conditioner also has disadvantages of higher price, higher maintenance costs, and other requirements for home decoration. So home users, you should choose central air conditioner according to the actual structural conditions at home.

How Central Air Conditioner Works
Here’s how a central air conditioner for home use works.

In the refrigeration process, the outdoor units absorb the refrigerant vapor from the indoor units and transmit the liquid refrigerant to each indoor unit after compression and condensation.
The energy regulation of the units is designed to be controlled by a microcomputer, and the variable speed compressor of the outdoor units will automatically adjust the working status according to the change of indoor cooling and heating load to meet the requirements of indoor cooling and heating load.

When it’s used for heating, the outdoor units absorb the refrigerant vapor from the condenser and then transmit the vapor refrigerant to each indoor unit after compression. Indoor units are installed on the ceiling. The air is sucked in through the air return outlet and sent to the room after heat exchange, and then the heated warm air is sent back to the room through the air return outlet in the way of local return air.

The Mitsubishi Brand
While you have understood the work principle of central air conditioner, it is also necessary to know the brand. You may have this question, if Mitsubishi Heavy Industries, Mitsubishi Heavy — Haier, Mitsubishi Electric are the same?

Actually, they are three different brands. In the past, the Mitsubishi Shipbuilding Company mainly focused on shipbuilding. With the development and adjustment of business, the company has integrated the internal combustion engine and aerospace industry and established Mitsubishi Heavy Industries, which is engaged in high-tech products and precision manufacturing.

After the separation of mechanical and electrical business, Mitsubishi Electric was born. Mitsubishi Heavy — Haier has no relationship with Mitsubishi Heavy Industries, Mitsubishi Electric and Mitsubishi Heavy Industries used to belong to the same company, but they are also different. Mitsubishi Electric pays more attention to appearance, function, and internal motor, while Mitsubishi Heavy Industries is famous for air compressors.

Mitsubishi Heavy Industries is a well-known Japanese enterprise, which has the same title as General Electric of the United States and Siemens of Germany.

In this article, we will take you to further understand the central air conditioner made by Mitsubishi Heavy Industries.

Award Winning Refrigeration Compressor
When you enter an air conditioner dealer shop and want to buy one, usually the sales staff will introduce the compressor of the air conditioner. In a refrigeration system, the compressor is the heart of the whole system. A compressor is responsible for increasing the pressure and the suction pressure to the discharge pressure. It means that the quality of the compressor directly affects the quality of the air conditioner.

For instance, the compressor of the central air conditioner of Mitsubishi Heavy Industries is imported from Japan, which adopts the most advanced 3D scroll DC frequency conversion technology.

The multi-point exhaust compression technology can also improve the seasonal energy efficiency ratio and the service life of the compressor. Designed and manufactured according to European quality standards, and with the most advanced frequency conversion control technology at present, Mitsubishi’s vector control technology can achieve the best energy-saving performance.

The outdoor fan blade of central air conditioners of Mitsubishi Heavy Industries is a three-piece design. Driven by a DC frequency conversion motor, the blade adopts a sickle shape design, and the outside adopts serration treatment, which can reduce the noise of the fan when cutting wind. It is helpful to realize more efficient heat exchange efficiency and improve the cooling heat rate by air agitation technology.

Mitsubishi Heavy Industries air conditioner adopts a 3D-shaped heat exchanger, which can exchange heat efficiently in a short time, whether it is in summer or winter to quickly make the indoor environment temperature comfortable.

Mitsubishi’s 3D scroll DC frequency converter compressor with this technology has won the 2006 technical award of Japan Refrigeration and Air Conditioner Society, and the professional evaluation of «small lightweight, high compression ratio, high efficiency and ultra-low noise under the same capacity.”

Quality Indoor Units
As the tail equipment of the whole central air conditioner system, indoor units are also important. The structural design and material selection of the indoor units affect the durability of the whole air conditioner system, as well as the comfort of using.

Mitsubishi Heavy Industries is famous for solid workmanship in the market, especially the structural design and material selection of indoor units. Compared with general brands, Mitsubishi Heavy Industries performs better in anti compression. The design of high strength helps to reduce the noise of the product and avoid deformation due to years of use. In addition, the indoor units with nanosilver mildew-proof antibacterial device can avoid the long-term accumulation of mold in condensate water, which will cause the secondary pollution of indoor air.

Hi-Tech Electrical System
Central air conditioner owes high efficiency to the allocation of the central circuit control system. Mitsubishi Heavy Industries adopts high-end intelligent temperature control technology, in which central air conditioner can achieve ± 0.5 ℃ of regulation.

As is known in HVAC industries, accurate indoor temperature control makes it more favorable for creating a constant temperature environment. Besides, it benefits the elderly, children, and people with a sensitive physique.

What’s more, the electrical system is added with a black box. When there are faults and the device stops, the black box will automatically save the data 30 minutes before the shutdown, which will help the maintenance personnel to analyze the reasons.

Besides, the electrical system applies the advanced communication mode Suoer Link II that can increase the signal transmission speed to 4 times the original, making the control of the system more accurate and faster.

This article takes us to look at the advantage of central air conditioner for home use. Also, you can know about choosing a central air conditioner. Based on the advanced technologies and the official energy consumption data, you will find that Mitsubishi Heavy Industries’ central air conditioner could be the best choice.
