Refrigerator development History

Records show that as far back as 1,000 Bc the Chinese cut ice in the winter and stored it to use in warmer weather. This method has been used extensively with ice houses being built throughout the 18th century specifically for this purpose. It is also known that in 500 Bc Egyptians made use of ice by placing containers of water out on cold nights to ice and stored for later use. The ice houses built in the 18th century were for both market and incommunicable use with wealthy families having their own ice house. Ice formed simply in the winter was cut into blocks and wrapped in flannel and stored in these houses many of which were incommunicable until required in the summer. Many ice associates were formed which had large ice houses and charged businesses and homes for ice to be supplied to them. Many homes at this time had ice boxes which were insulated containers in which food and ice were stored together and as the ice melted more was purchased.

Refrigerators work on the principle of taking a extra type of gas that when it's compressed it turns into a liquid which absorbs heat. It took 100 years and results from four main inventors before a working refrigerator engine was invented and patented in 1834 by Jacob Perkins. The population who pioneered the way to this invention were in 1720 a Scotsman called Dr William Cullen who carried out experiments in evaporation. Next was Oliver Evans of Pennsylvania who designed a compression engine that was never built but his institute was used later. Michael Farady was the first to in fact furnish a expedient that cooled using ammonia in 1820. Jacob's engine which used ether for cooling failed commercially simply because everybody seemed happy with using natural ice supplied from ice houses so he moved into printing instead.

The rest of the 1800s concentrated on refrigeration on an market and market scale as household enterprise would not pick up until the 1900s. From 1937 James Harrison worked on perfecting a cooling engine to be used in countries like Australia where huge amounts of ice were not available to store for summer months. It took him till 1856 before he got it right and had a engine built in a large brewery to keep beer cool. This refrigeration engine for cooling beer was the first market cooler used in industry and adapted for use in discrete environments.

This soon resulted in ice development factories that competed with the ice houses that used natural ice with the ice development machines proving to be better. For in the warmer winters the natural ice stores would not have sufficient to supply ice all summer whereas the mechanical ice makers could work all year round. Gently from 1900 domestic refrigerators were introduced onto the store with tiny interest until normal electric introduced the Monitor Refrigerator in 1927 and that is when the group in fact started to take domestic refrigerators seriously. Today refrigerators can be found in 99.5% of homes around the world.
