We all attach a utility with every object we buy. One of the basic things we expect from an air conditioner is that it should give good cooling. Faster or slower, but it should cool well in order to get the temperatures down to comfortable levels. When it does not do so, we do not derive utility from the product and want to replace it. But these questions arise in several minds: “Why is it that my AC which was cooling well till a few months back is not cooling well now?”, “I bought a new AC but why is it not cooling well?” or “This AC used to work really well a few years back but is ineffective now”. There can be several reasons for the same, some of which can be technical faults as well. But here we would try to explain some of the reasons, which may not be fault in the AC itself. One of the common complaints from people living in northern part of India during peak summers is that the AC is not cooling effectively or the compressor is not working. Unknowingly while installation of the AC, people do not realize that the outdoor unit (in case of split AC) or the outer part of the AC (in case of window AC) is directly facing the sun.

All ACs have an optimum operating temperature (ambient or surrounding temperature) at which they can work most effectively. If the temperature increases beyond the optimum temperature, the efficiency of the air conditioner goes down and it can also reach a stage where the compressor stops working completely. At lower efficiency, it can also consume more electricity than that mentioned on the BEE label. ac unit overflowingTypically numbers on BEE label are in test conditions.1 ton split ac compressor price: This happens because the job of AC is to take heat from inside the room and throw it outside. air handling unit ituBut if the heat outside itself is quite high, then it is not able to do its job properly. Air Conditioners are designed to work at a certain optimum ambient temperature and beyond that they stop working.

How much is optimum temperature? For most ACs it is about 46-48 degrees. Beyond which they can become less effective or may even stop working. These days some brands have models that can handle up to 52 or 54 degrees. Solution: The best thing that you can do is to avoid installing an AC in such a way that it faces direct sun or is in a place where there is lot of heat. And it is not necessary that heat can happen only in a city where the temperature goes high. It can happen anywhere if the ODU is in closed hot place. Also one can even use an AC with optimum temperature of 46 in a place where the temperature goes high. It would just need a place where the surrounding temperature is low. This can be achieved by placing plants around the AC or by pouring some water on it occasionally (although it can be cumbersome), or by any other creative idea. One of the common mistakes people make is that they buy AC just based on their budget and not based on the requirement of the room.

A small AC in a huge room will always find hard to cool the room in peak summers. Thumb rules for sizing ACs do not work always and one has to look at several parameters while sizing air conditioners. Certain cities are hotter in summers, which mean they require more cooling for the same size room as compared to cities where temperature is less. Some cities are more humid than hot and so the cooling requirement is less, but what is more important is humidity removal. Thumb rule of 1 ton for 100 sq ft (most commonly used thumb rule) does not work always and one should make sure that proper sizing is done before buying AC so that there are no regrets after the purchase. Yes aging not only impacts humans, but appliances too. With time efficiencies of most appliances come down. Cooling of an air conditioner reduces with time, or I must say with time it takes more electricity to give the same amount of cooling. As per ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) an air conditioner reduces its efficiency by 7% in the first year, 5% in the second year, 2% every year in the following years, and this reduction peaks somewhere between 20-30% depending on how well the air conditioner is built.

If the AC is 20 yrs or older, it can go down up to 40%. (Source: “A Survey of Refrigerant Heat Transfer and Pressure Drop Emphasizing Oil Effects and In-Tube Augmentation;” ASHRAE Winter Symposium of 1987; Schlager, Pate, and Bergles.). This means that the older the AC, lesser is the efficiency. So it is not only the improvements in energy ratings by BEE (Bureau of Energy Efficiency) that leads to lowering of star rating for your AC, but also the de-rating factor which can lead to more electricity consumption than mentioned on the BEE label. Some manufacturers have models that have reduced de-rating, but no one has been able to completely eliminate it. It is not always a technical fault that may lead to less cooling or an ineffective AC. One should make sure that the sizing is done properly and the AC (ODU/external part) is not placed in a very hot environment, as it reduces its efficiency and leads to improper cooling., , , ,   »  Shinco – 10K BTU : Portable Air Conditioner Review

SummaryDescription of the 10K BTUTechnical SpecsProsConsUsers’ feedbackConclusion One of the most important factors to consider when choosing an air conditioner for your room is the rated cooling capacity. Air conditioners with high cooling capacities are suitable for large rooms and vice versa. This portable unit is designed to offer a cooling capacity of 10,000 BTU. At this capacity, this sleek unit is ideal for cooling a space of 300 square feet. The system is specially designed to spread the air evenly across the room. In case you are looking for a powerful system for your house, then this unit is designed to transform your space into a comfortable place with cool, clean, and fresh air. In addition, this unit employs a self-evaporative mechanism to eliminate the need for regular emptying of the tank. If your room meets the size specification given by the manufacturer, then this maybe the ideal system for your cooling needs. To begin with, this system is designed to provide the user with cool and fresh air.

With a cooling capacity of 10K BTU, this system cools a room within a short time. According to the manufacturer, this portable unit is suitable for rooms that are as big as 300 sq. ft. It is also important to have in mind, however, that the size may be influenced by the design of your house, and the conditions in which it is tested (temperature, humidity, isolation). In our case, with a room around this size and average ambient conditions, this system was able to provide a comfortable environment in a few hours. The overall performance of an air conditioner is significantly influenced by how it is designed to blow air. This unit is capable of blowing air in four directions to ensure that your entire room is cooled and has a comfortable environment. This is very unique, and works well for its 2-speed cooling. This system spreads cool air throughout the room quickly and effectively.This unit is designed for easy mobility to enable users to move it from one place to another in a stress-free manner.

It features wheels and you can therefore wheel it from one position to another without the need to carry it. Furthermore, the system has side handles that enable users to carry it up the stairs easily and comfortably. This unit only weighs 54 pounds and it is therefore lighter than most air conditioners of same cooling capacity. This is a big plus. Everybody likes controlling their devices and systems from anywhere within the room. The Shinco 10K comes with a remote control to enable you to adjust your room environment without walking to where you have positioned it. Moreover, it features a user-friendly interface that is made up of digital controls. With this interface, you can adjust the conditions of your room with ease and convenience. Lastly, manual emptying of an air conditioner’s tank can be tiresome especially when it becomes a routine task. This air conditioner is designed to provide you maximum comfort and does not require regular emptying of the condensate. It utilizes a self-evaporative mechanism that prevents accumulation of the condensate.

The system is designed to work effectively and does not come with a water tank. Instead of allowing the condensate to accumulate in a tank, the unit recycles the water and uses it for cooling.Remember we are dealing with AC units, there is no such thing as quietness! However, this unit is pretty non-noisy, which we liked. The manufacturer indicates 52-55 dB, we are more inclined to think it ranges within the 58-60 dB according to our measurement. I have lived in my apartment for close to 8 years now and just suffered through hot days without A/C. It can get up to the high 80s-low 90s on really warm days inside. While it is great for keeping the heat in during the winter, there were stretches I literally couldn’t even stay in my house. With giant sliding windows, I couldn’t just get a decently priced window A/C. With the first hot day this year, I logged on and ended up buying this unit. I have been using it for over a week now and couldn’t be more pleased. I have it in bedroom which is about 14X15.

The included window unit was easy to use. The bracket has some holes with a screw so I could adjust for my vertical window which is about 4 feet tall. I had the unit up and running in about 15 minutes. It can cool down my room very quickly. Within 20 minutes, it is comfortable. I think sound is subjective. I have a large industrial fan that I had used for years that is just as loud. I am use to a lot of noise so this doesn’t bother me. When it transitions between the compressor and the fan though, there isn’t a giant jolt of sound so it hasn’t woken me up. This is my first Portable Air Conditioner. Very easy to assemble in sliding windows. The two-piece window kit will fit up to 52 inches length. My window is wider than 52 inches so I needed to buy some weatherstrips at homedepot to fill the space. This air conditioner works great and fast. Could be a bit noisy for some people if you would like to use this unit in TV room or bed room.On the User manual: This product has a self-evaporative system.
