What are the differences between chiller and fridge
Chiller and fridge are both cooling machine that can cool materials down. However, there are still several differences here. The differences are as follows:
- Differenceof temperature range. Chiller cools liquids only and in the temperature range of 7 to -1 degree celcius. Fridge extracts heat from the same as freezer but the range is only from 3 to 5 degree celcius.
- Different fields and materials. Fridge is more used at people’s kitchen, in order to keep food and beverage fresh and cold. So the using field of fridge is people’s home. Chiller is widely used in industrial field, chemical field, biological field and other fields. Therefore, chiller is used to cool chemical substances and materials.
- What’s more, chiller is more large-scale than fridge. As we all know, fridge is most used in home kitchens, while chiller is mainly used in industrial factories, chemical labs and other big places.
How can calculate chiller efficiency
There are three efficiency calculation approaches for chiller, including tons of refrigeration, efficiency formula EER = Btu/hr cooling/watts and dividing the 846,000 Btu/hr by the 69.06 kW-hr consumed to yield an EER of 12.25, and a COP of 3.59.
These three efficiency calculation approaches are quite precise, because they are not general estimations but precise formulas. Calculating precisely is very crucial to estimate a chiller is good or not, and also to choose a proper chiller.
