Apart from the size of these machines, there were other reasons why it was not practical to have one installed. The cost was astronomical and far beyond the reach of an average household. 

With the idea that preserving your food would save money on wastage it didn't make sense to make the investment.

 Really, only commercial enterprises that had them and they were used to store food before going to market.

It wasn't until 1927 that the use of the smaller units became popular. General Electric made a sulfur dioxide based refrigerator and actually produced over a million for the general public. 

With this model the public were finally able to practically refrigerate food in the house. 

There are still working models around but because of the danger that comes with sulfur dioxide it's illegal to refill them if they break down.

By the thirties, 60% of US Households had a home refrigeration unit but it was in the seventies before the same happened across Europe. 

Now this style of the American fridge freezers has been used around the world. The side by side design is instantly recognizable as many come with an ice dispenser at the front. 

It was in the forties that separate freezers were popularized but mass production was not immediate. It was after the end of world war two that they were in more and more households. 

The peoples uptake on the separate deep freeze system was helped by advances in defrosting which was now automatic.

These days, refrigerators are in every household and they come small enough to just chill a pack of beers. Some that are in development will even monitor walk in cooler what you take out and use and will create your shopping list. 

The list can then be activated and the food ordered and delivered from your local supermarket. 

All these things in the pipeline and new innovations becoming available every day so the next generation of refrigerators will be more that just cold food storage.

Depending on the needs of the customer, refrigeration models are varied from smaller under-counter types, builtin refrigerators and large American refrigerators with ice and water dispensers integrated to the door.

Today's modern refrigeration is all about convenience, practicality and size. Whether purchasing a space saving integrated refrigerator or a super-sized American style refrigerator, there is something available for all types of families- large or small. 

And, of course we want the refrigerator to look good, but mainly we want to be able to store a full week's worth of shopping in it and know that it is still going to run energy efficiently.
