Refrigerators improve energy savings through heat exchange
Thread Content
After operating for a long time, a layer of oil film forms on the refrigerant side of a chiller, which can turn into carbon deposits that hinder heat exchange and thus reduce the efficiency of the unit. In all cases, energy savings for chillers are achieved through the use of variable frequency drives and the cleaning of the condenser, such as regular cleaning of the condenser using gel balls. So far, no products that offer energy savings on the refrigerant side have been released. In the United States, test experiments covering the entire lifecycle of refrigerators were conducted last century, and the use of refrigerant additives has since been widely adopted to solve this problem.
It’s a good idea; no corresponding products have been developed in China yet. Imported ones must be quite expensive, right? Are there any comparative data available? Is the ratio of energy savings to investment appropriate?
It’s not available in China, but it is available in the United States. The payback period for just this additive is two years; for older machines, it’s at most one year, as no further addition is needed after just one application
Give it some support – the questions raised by the teacher are great and really worth learning from*.
