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 recipe 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 commercial and inexpressive 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 inexpressive until required in the summer. Many ice companies were formed which had large ice houses and expensed 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 motor was invented and patented in 1834 by Jacob Perkins. The habitancy 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 motor that was never built but his found was used later. Michael Farady was the first to absolutely furnish a expedient that cooled using ammonia in 1820. Jacob's motor 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 commercial and commercial scale as household enterprise would not pick up until the 1900s. From 1937 James Harrison worked on perfecting a cooling motor to be used in countries like Australia where huge amounts of ice were not ready to store for summer months. It took him till 1856 before he got it right and had a motor built in a large brewery to keep beer cool. This refrigeration motor for cooling beer was the first commercial cooler used in manufactures and adapted for use in varied 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 enough to supply ice all summer whereas the mechanical ice makers could work all year round. Gradually from 1900 domestic refrigerators were introduced onto the store with tiny interest until general galvanic introduced the Monitor Refrigerator in 1927 and that is when the social absolutely started to take domestic refrigerators seriously. Today refrigerators can be found in 99.5% of homes nearby the world.
