Chiller Efficiency

Hi, hoping someone can help please?

I am conducting some research into chiller efficiences and would really like some advice and answers to the following questions:...

In terms of running a shop keeper's chiller/fridge as efficient as possible..what are your recommendations to achieving this?

If a retailer was to turn their chiller off in the evening, does this save them money overall or will they use more power by switching it back on in the morning? Does it make a difference?

Is it more cost effective and energy efficient to have the chiller maintaining a constant temperature?

Maintenance: What conditions make a chiller break down? What are the best practices to maintaining a fridge/chiller to preserve it's lifecycle?

Many Thanks in anticipation.

By the term Chiller, do you mean water chiller or a fridge that keep food chilled?

Are you in the refrigeration industry in some way?

Hi, a fridge that keeps beer chilled. I work in the beer industry and I am researching the efficiencies of fridges and their ability to keep drink cold. Any help on my questions would be much appreciated.

Beer industry is very important one;)

I will be back later to help you.

Great thanks for your help..will hear back from you soon.

All these small units works usually up to 75% of the time.
In a shop when they are open and closed rapidly, they can run all opening hours.

Broken door seals allow warm humid air to enter and cause extra working hours.

Insulation in the walls and door plays a major factor as well, having heating element on the door's glass will draw more working time.

in general, efficiency the unit output in watt divided by the electricity dawn by the cooling unit in watt.

If the fridge and chiller are opened many times a day and warm bottles are entered, it is very difficult to check efficiency and at the bottom line it leaves you with the manufacturer state of efficiency.

Hope this helps you in your research.

supermarkets use a night set back or used to raising temp a couple of degres over night also night blinds and pulsing fans when on down time or shop closed if you increase yr insulation on cab can help as said an door open times help as well also putting in a cold product and keeping it full with cold product as well minimise air space in cab have seen bars load cabs with glasses this causes extra work when door open all the cold air falls out have watched units like this (yeah am a sad fridge man lol) an it causes extra work and extra breakdowns as for maintenance keep the condenser clean allow room for air flow round unit have seen loads rammed under bars that dont work cos no airflow pull them out they fine especially when ambient temp rises have seen bars use a glycol system seemed to work ok not convinced though cant beat a unit ya can drag out and replace or fix hope this helps sorry if i went on a bit lol :confused::D:rolleyes:

oh and as for turning unit off over night if u take a large glass door cocacola fridge and fill it full with warm cans at room temp takes 24hrs to chill them down beer might be same

doesnt hurt to turn fans and refrigeration off when loading with goods,this will lessen ingress of heat.
bottoms up
