History of Air Conditioning

Since the early days of mankind, ice and snow were used for centuries for refrigeration and chilling. We moved from collecting ice and keeping it for use in summer time in the late 17th Century when mechanical ice making commenced. 

Early civilizations

The early civilizations created their own methods of cooling depending on their geographic location and available materials. The ancient Egyptians used wet reeds on windows which was perfect for its dry and arid climate. The Romans had aqueducts in their walls while the Persians used cisterns and built wind towers for cooling. 

The Chinese during the time of Han Dynasty around the 2nd Century invented the rotary fan which was at that time powered by prisoners. By the 8th Century, around the time of Tang Dynasty, this had evolved to cooling halls with water-powered fan wheels and jets of water from fountains. 

Mechanical cooling

Remember Benjamin Franklin? 

In 1758, Franklin along with a British chemistry professor named John Hadley of Cambridge University were the first to successfully establish that evaporation of volatile liquids could be used to lower temperatures. In 1820, Michael Faraday, the British inventor best known for his discoveries in electromagnetics, made a breakthrough in advent of compressor technology. He discovered that if ammonia was compressed, liquified and then allowed to evaporate, air surrounding the area of evaporation could be cooled. This paved way for various compression refrigeration systems which were used to cool air and make ice until the early 1900s when electrical air conditioning arrived.  

Electrical air conditioning

Have you seen Carrier brand of air conditioning units in the market or in TV ads? 

Well, the first modern electrical air conditioning unit was invented by Willis Carrier in 1902. It was built to actually regulate temperature and humidity in a lithographing process at a factory where Willis Carrier was employed. Carriers invention not only controlled the temperature, but also controlled the humidity by passing air over cold coils which were filled with cold water. 

Very soon Carrier’s technology was used in all types of workplaces to improve productivity and its rising demand led to the formation of The Carrier Air Conditioning Company of America. It wasn’t long before residential and automobile use cases for air conditioning became common. 

The last of the most significant inventions in the history of air conditioning came in 1945 when Robert Sherman invented the portable, in-window unit which carried out all the functions related to cooling, humidity and filtering.

With multiple functions being carried out by modern aircon units, the AC units in our homes today are highly complex. This gives rise to the need for regular AC servicing arises. Aircon maintenance is an easy task if done with the right service provider and at the right intervals. Available on iOS App Store and Android Play Store, Sendhelper is a platform which allows you to book necessary aircon maintenance services in Singapore at an affordable price and at your own convenience.

Clean homes lead to lower stress levels

The year just started! This often goes hand in hand with spring cleaning. Cleaning has spillover benefits into different parts of our lives. This 2019, consider the long-term impact and intrinsic motivators to cleaning your house. Here are some tips to help you persist through the process of cleaning.

Clearly define your needs and priorities

Some contend that the state of our house is the reflection of our inner beings. Research has found that physical clutter adds to your stress. However, this need not be the case.  When people clear their homes, they often jump straight into throwing things out based on what they feel. This works if what you’re cleaning happens to be in small amounts. However, quite a few of us are guilty of accumulating piles to the extent of hoarding and cluttering our homes.

Set the parameters straight

Define guidelines for yourself on how you should categorise your belongings first. Your priorities and goals should direct what you want in both your life and your homes. Many tend to give up on cleaning after feeling overwhelmed by the clutter. These questions, however, can mitigate these sources of anxiety when it comes to cleaning:

  1. What are quantifiable goals you would like to set for yourself and your family?
  2. What are your top 10 list of priorities as an individual and a family?
  3. How can your house be structured to meet these priorities and needs at all times?
  4. What are things in your house which don’t support these goals?

These may sound like very obvious questions. However, many of us have piles of items stored for years in our homes which may never be used at all. It is important to be able to define our needs and wants. This is not exclusive to just the aesthetics of our homes. It also improves our overall well-being too. 

Clean living room
Who doesn’t love a nice clean living room to come home to?

You don’t need most of it

The truth is, we probably don’t need most of the items we have. Remember the outfits bought during sale but never worn? Or the lamp bought a while back because it was fancy? These are just a few examples of many things we don’t need. Faced with the stress from work or school, spending money has become means of therapy. Unfortunately, this adds to the stress in the long term. It makes it difficult for cleaning tools to move around the house. This may make us feel that cleaning is a challenging process when it doesn’t have to be!

Another issue with clearing our old items is the nostalgia attached to it. Items which remind us of relationships which we once shared leaves us in a state of standstill. Decluttering can at times help us move on too.

Engage help to clear the clutter

Cluttered spaces are often hosting spaces for pests such as cockroaches and termites. The accumulated moisture in corners are also conducive for mould to fester in. You may want to hire professional cleaning services to help you clear this. This is because professional expertise in these matters would present a higher chance of your home being restored to its original state!

There are also several cleaning services which are available in Singapore to help you with clearing old items and with issues of pests and mould. With a variety of cleaning services ranging from specialised deep cleaning to regular home cleaning and part-time helpers who help you with simple cleaning tasks, Sendhelper caters to your budget and cleaning needs.
