The efficiency of air conditioning systems varies from one device to another. If periodic maintenance of the system is regular, the efficiency of the air conditioning is high, and the indications are that it can work at the maximum load conditions. This gives the system a maximum life span in addition to an optimum operation at the maximum thermal load conditions. Another factor that increases the efficiency of air conditioning is the cleanliness of air filter and fins of the evaporator. Dirty and dusty filters & fins lead to multiple failures, including frost along the whole length of the coil of the entire evaporator up to the compressor beside the fall of condensation water of the device and the weakness of the air flowing into the room. On the other hand, when the fins of the condenser located in the external unit are unclean and the fan capacity is very low, this leads to high pressure, which causes compressor damage due to high pressure, temperature and continuous work. Furthermore, when the current (watt) consumption is 15-30% less than the normal value of a system, this indicates that there is a blockage in the cooling circuit or that the cooling system quantity inside the system is less than the planned one.
2.3.3 External factors affecting the performance of the air conditioning system
2.3.3.1Atmosphere temperature
When the external temperature is higher than 40 °C, the difference between this temperature and the required degree inside (22 °C) is significant,
As I’ve progressed in life I’ve found that maturity has always been one tool that I’ve held over the majority of my peers. Turning eighteen and realizing that my cushiony life will soon turn turbulent due to the thunderstorm that is adulthood has made for extensive research in the career that I want to pursue. It’s difficult to assess the career that I want to hold in all phases of my life in eight pages, however, research and planning has alleviated headache for the future. The HVAC industry is a complex network of exciting positions that offer job security and healthy salaries. Due to the relatively expeditious schooling that is required to be qualified to work in HVAC and the apprenticeships available, the future will be fruitful. From
Freon is a gas that is added to the compressor of an air conditioning unit. It is then added to a closed loop system that ensures there is a constant recycling process that it goes through. The way it works from there is when you turn on your air conditioner the compressor compresses the Freon. This makes it become hot and then it travels through coils that are inside of your unit. As the Freon liquid flows through, it evaporates and becomes cold. The now cold gas will continue through the air conditioners coils to absorb heat and then push cooler air into the building or
Keeping your AC unit clean can keep it running proficiently and help it last longer. Ideally, it is a good idea to have a professional service to look at your system from time to time; however you can do your part in between appointments.
In passage Air-Conditioning Will Be the End of Us by Eric Klinenberg he builds an argument using persuasive elements such as fear tactics, facts and statistics, also word choice to support his claims and try to and persuade the readers that the amount of AC use should decrease
High outdoor temperatures are hard on cars, and operating the air conditioning adds to the stress on the cooling system, belts, hoses, and more. A properly operating air conditioner will not only provide for your comfort, but will cause less work and wear on the vehicle's systems.
Installation or fixing HVAC systems is not always a simple task given that there are certain methods that must be undertaken so as to guarantee right functioning of the said units. Except if a certified professional attends to the
Nothing can ruin your summer faster than a broken air conditioner. Ensure that your air conditioning unit is running smoothly this summer by getting it regularly serviced. Every three months, it is suggested that you:
The room temperature was measured throughout the lab and kept constant at 24°C (+/- 1°C), as the lab was conducted during the same time of

The heater or air conditioner unit has impacted my life this past week in a good way. It has impacted my life in a good way because these past few weeks it has been very cold and a storm has even came through this side of the country. We had a lot of ice and some snow which of course is really cold so because of my heating unit that is outside of my house I was warm the entire weekend. Even when the roads had cleared up it was still chilly outside, I was thankful that I had heat in my car as well to keep me warm as I drove to work the next day. Without a heater or air conditioning unit at my house and in my car it would have been as cold on the inside as it was outside making my weekend very uncomfortable. The air conditioner is also really
The Social Security system, the people’s retirement system, is running out of money and it is time for it to be privatized. Since being created in 1935 by President Franklin D. Roosevelt, people have grown more dependent on Social Security for their retirement and the system can only be sustained for so long. In a 2015 Gallup poll, 46% of those polled said they “personally worry about the Social Security system.” The same Gallup poll also found that 36% of retirees expected Social Security to be a “major source” of their income in retirement. People are worried with good reason. The current system cannot sustain itself.
I learned that H.H. Holmes was very, very good at murdering people and using creative ways to get away with it. In the process of researching I learned that our school has given us a lot of different databases to help with our projects and that finding primary sources are not as hard as I thought it would be. Working on this project I learned that by splitting up the steps of the process of writing an essay I can use my time more wisely. When I was writing this I had already had all of the foundation pieces there to help me. This made the physical writing of the essay gp much more quickly than past essays I have written. While looking for sources I found many that were not credible. I found out how to find correct sources that would
The Harry Potter novels by J.K. Rowling are a well known and highly celebrated series. In the first novel, Harry Potter and the Sorcerer’s Stone, the audience is introduced to the main character, Harry. Harry is an embodiment of many common themes and devices in literature. However, Rowling manages to employ these literary tropes while creating a story entirely different from any other. The novel Harry Potter and the Sorcerer’s Stone provides an example of how to effectively utilize common literary motifs and archetypes without being cliché.
