What to Consider When Choosing a New AC System

Air conditioning has many benefits but also several drawbacks. Air conditioning is great when the weather is hot, most of the time. When the air conditioners are cooling a large building, though, they can be very noisy and sometimes ruin the ambience of a building or business by making it feel stuffy. This is why there are some tips in choosing air conditioning units that should be followed.

It is recommended that you avoid ductless air conditioning units. Ductless units are cheaper to buy but can be loud and annoying. Also, a good air conditioning unit does not need to run all the time; therefore, you won’t have to waste energy cooling off your windows all the time. Finally, a good air conditioning unit will only require about 20 Btu per cubic foot whenever you plan on cooling down a room. So, if you intend on cooling a single 225 square feet room, you can get away with only a 2,500 Btu air conditioning unit in your window area.

However, when you plan on installing central air conditioning or a ductless unit inside your building, you should still calculate the space that will be cooled using this unit. This way, you will be able to get an idea of how much space you will need. The same goes when choosing an air conditioner unit for a small room like a bedroom. You should also consider the type of unit you want inside your home to avoid wasting money buying something that is not suitable for the room.

The first thing that you need to do when choosing fujitsu air conditioning is to check out the different available models. With the internet being one of your reliable resources, it won’t take you long to be flooded with many different models. Browse through these models and see what you think is suitable for your needs. It is also essential that you get an idea of the prices. Choose units that fall within your budget but make sure that they are efficient enough.

If you plan to install new air conditioning in your home, then your initial consideration should be energy efficiency. This is because most homeowners unit today comes with high energy efficiency features which help you save on energy costs. Therefore, as a homeowner, you must consider getting a unit with such features.

On top of choosing the best air conditioning unit for you, consider its climate control feature. Some models come equipped with automatic climate control. As a result, the unit will detect the temperature and change the AC settings accordingly. On the other hand, some models do not need any manual intervention from you. Instead, you can program its settings based on the weather forecast.

Another important consideration is energy efficiency. Remember that a good air conditioning unit does not consume too much energy. Therefore, get one that has the highest energy efficiency rating possible. This is critical, especially if you think of replacing your existing air conditioning or installing a new HVAC system. Therefore, you should choose an energy efficiency model even if it is more expensive.

In conclusion, when it comes to air conditioning units, you must choose durable, efficient units and offer reasonable climate control. As you consider these factors, remember to check out different models to make an informed decision. Get expert advice on how best to utilise your current system or what model to purchase. Then, get the best air conditioner for you!

The Convenience and Modernisation Brought By EnviroTemp

The most revolutionary innovation when it comes to improving the efficiency of heating and cooling units comes in the form of EnviroTemp. The idea behind this technology is to make your heating and cooling system in your home doubly effective, while likewise extending the life of the equipment.

Many Australians are captivated about Mannix Envirotemp because they’ve heard a lot about it, precisely the prospect of substantially decreasing maintenance expenses. However, the truth is that the most crucial advantage of it is that it minimises the carbon footprint of the appliances you are using in the house or at your office.

Air conditioning and refrigeration are indispensable components in any domestic, commercial, or industrial environment. In a residential setting, it is tough to think of how you can maintain comfort and convenience without your AC system as well as your heating equipment.

While you can use your appliances without the requirement of technological innovation like EnviroTemp, the fact is it wouldn’t harm if you utilise it. The truth is you can save up to 60% of the average energy you’re using every year, plus you get to enjoy the very same level of convenience all the way.

The idea behind EnviroTemp is to come up with something that will extend the life of your A/C, fridges, freezers, and other cooling equipment without jeopardising comfort. For most people, the concept of embracing efficiency is by adjusting the temperature level of the A/C system.

However, doing so suggests you probably will sacrifice convenience. What if the temperature outside is scorching hot? Can you still afford to change the temperature level inside?

EnviroTemp enables you to turn up the air conditioning system and other home appliances that promote a comfortable environment without the concern of having to pay for increased energy expenses. It is a highly concentrated premium oil-based material that works by forming an irreversible layer in the refrigeration circuit of your unit.

Mannix Envirotemp provides security that traditional oil cannot give. By applying it to your system, you guarantee that refrigerant will travel through the system without issues.

Another remarkable feature of EnviroTemp is that the treatment process is convenient and quick to take effect. Any certified or experienced A/C service technician can do it; however, we do not recommend a do-it-yourself approach. If you have a typical small system in your home, you expect the results to appear in a matter of days, while larger systems will need to wait at least a week for the advantages of EnviroTemp to start surfacing.

Most homeowners do not realise that oil-based refrigerated systems are likely to lose about 25% of their efficiency after a couple of years. With the help of EnviroTemp, you increase the chance of not needing to replace your equipment for several years to come. That alone is something worthwhile of your attention.

Cinema Screens & Motorised Curtains: Screen Space – A scholarly discussion

How much may a technology develop from its own internal demands, how much may it be affected by the circumstance of its deployment? Until now, movie goers have given scant attention to the movie screen itself. Put simply, the screen has been invisible, although it is the most visible piece of film technology. The screen demands more attention because of its peculiar status: it is both the final link in the chain of film technology as well as an element of architecture, defining – and being defined by – the space it inhabits. We shall look at the differing ways the screen of the past was situated in architectural space, how these factors have affected our viewing of movies, and, finally, how they helped determine the development of film style.

“Where do you like to sit when you go to a movie?” The placement of the screen in architectural space is a key determinant in how we experience a movie image. 1995 marks the o­ne-hundredth anniversary of the first projection of motion picture film upon a screen, yet what exactly do we know about the motion picture screen itself? Oddly, this most visible piece of filmic illusion is the o­ne thing both film history and theory have most overlooked. As the key element in our experience of watching a movie, the most distinctive aspect of the screen from the first motion picture performance o­n is what has also remained most constant about it: the screen leads a double life! It is both the final link in the chain of film technology as well as an element of architecture, defining–and being defined by–the space it inhabits. If the screen has been overlooked in both its roles, this is because critical writing o­n both architecture and film technology has seen the screen as essentially passive.

A comparable sense of passivity has affected our view of the screen in its technological role. Most of the writing o­n the “technological apparatus” of movies has focused entirely o­n image creation (the camera, lenses, lighting, film stocks, etc.) and, to a lesser extent, image production (the projector). As a reflecting surface the screen apparently limits itself to giving back unchanged the images presented to it. For this reason the screen has found its place in film studies primarily as metaphor, its very passivity facilitating its transformation into other things. But in point of fact the motion picture screen has always played an active role, both as an element of architecture and an element of technology. And it has done so in a way that reflects back o­n other aspects of film technology.

Rather than attempt a complete history, I’d like to establish a critical way of thinking about the screen in its history. My starting assumption is that there are both constant and variable dimensions of the screen in its dual architectural and technological guises. If I can establish the constants, I can then chart a history of the screen by looking at the variables, which have generally centered o­n size in relation to theatrical space, shape, the placement of the screen in the auditorium, and reflectance. In doing this, I hope to demonstrate how the screen itself might have influenced the development of film style.

Architecturally, the o­ne constant is a seemingly simple o­ne: the screen always occupies a fixed point in architectural space. In this regard, the screen does place definite constraints o­n theater architectural space. From a simple condition of fixity, the screen establishes the possibility for fairly radical departures from traditional stage theater design. The screen might reflect a good deal of movement, but the audience’s attention is effectively always fixed o­n o­ne object, the screen itself. With stage theatre, o­n the other hand, audience attention may be selectively directed by movement along the whole width of the proscenium. For this reason, stage and screen theaters create a different spatial relationship between spectators and spectacle.

The positioning of the screen in architectural space might function as a constant, but the construction of the space around it is a variable. In a 1931 article in the Journal of the Society of Motion Picture Engineers, the proper relationship between movie theater space and the screen was defined by three conditions: 1) the minimum desirable width is o­ne-sixth the distance of the screen from the farthest seats, 2) the maximum desirable width is eight-tenths the distance of the screen from the front seats, and 3) the intensity of lamps is an important factor limiting screen size. To some degree, this formulation still treats the screen almost as an afterthought, since theatrical space here determines screen size.

Consider, also, the relationship of screen size to the depth of the auditorium. First of all, the screens are doubly framed, a smallish rectangle of light set in black masking that is then framed by a fairly large proscenium. Masking had the odd effect of making a small image seem even smaller and at a great remove from the audience. Second, small screens in very large halls made it difficult to see details in any shot further back than medium distance and the black masking exacerbated the problem by reducing visual acuity.

Given the size of the image, the double framing of black masking and proscenium, and problems in visual acuity, the basic style of the standard Hollywood film, with its emphasis o­n telling close-ups to direct audience attention, might be a function of the conditions of reception.

Can we assume that there is a correlation between film style and architectural space? It is worth noticing that the advent of shallow focus as a dominant style follows the large theater expansion of the 1910s and 1920s. Though Andre Bazin assumed that shallow focus resulted from editing procedures intended to focus audience attention, it is just as likely that both editing and shallow focus are in part determined by another external constraint: theater space.

One concrete piece of evidence that might clarify the extent to which filmmakers were thinking about the screen in relation to architecture as a stylistic constraint: the early attempts at wide gauge filming in 1930-31. Because there was no way of reducing the wide gauge image o­nto conventional 35 mm film as CinemaScope would eventually allow, filmmakers had to shoot two different versions, o­ne in wide gauge and o­ne in 35 mm. The wide gauge film powerfully changed the existing relationship between image and theatrical space in a manner that had consequences for conventional stylistic practices. For example, the 35 mm camera is clearly more emphatic in directing viewer attention, moving viewer’s eyes to the foreground center by blocking off background activity. This neutralizing of background cannot simply be a function of the lesser width, but rather, is a consequence of the overall smallness of the image in relation to the vastness of the auditorium space.

Turning briefly to screen technology, I feel I have to emphasize that there is technology here. It’s easy enough to think of the screen as little more than a fancy bed sheet hung o­n a wall, but movie screens are not simply built, they are also engineered. This was made most evident to audiences with the Cinerama screen, which was promoted as an engineering marvel. Cinerama could play o­n depth perception not just by extending the width of the screen, but moving into areas of peripheral vision, which necessitated a deeply curved screen. The deep curve, however, created a light problem, and to ensure even illumination across the image, Cinerama engineers devised a screen made up of a series of strips, with the angle of each strip adjusted according to its position o­n the screen. The Cinerama screen itself presented the illusion of a single, continuous surface that was not in fact there.

With sound film, speakers were placed in back of the screen, and the screen had to be shot full of tiny holes to allow for sound transmission. This perforated screen remains a standard for theaters to this day.

From these two examples of the louvered and perforated screen it should be evident that the screen as an element of technology does not simply receive an image. In fact it would be not accurate to say that no image exists until the screen acts upon it, reflecting light back toward the audience in a way that allows interpretation of a coherent image even if the screen actually fragments that image.

This leads us to recognize the o­ne constant of screen technology: it must always offer sufficient light reflectivity to produce an image that is clearly discernible to the entire audience. No format other than Cinerama demanded such a radical reworking of screen design, but through much of the screen’s history its activity as a reflector was the central concern for screen engineers. With the sound screen, for example, could you have perforations sufficiently large to transmit sound yet sufficiently small to remain imperceptible to the audience? While the holes do not interfere with the illusion of the image for most seats, they do nevertheless always affect reflectance. Screen reflectance, then, is no simple matter.

The limitations of the technological screen had consequences for film style similar to those created by the constraints of architectural space. For o­ne thing, problems in fulfilling the demands of the screen’s o­ne technological constant of sufficient reflectance were as conducive to a close-up style with shallow focus as the problems created by architectural space. Furthermore, at low illumination levels shallow focus helps an object stand out against background more forcefully than it would in a sharply defined image which gives all objects equal value.
