What is a common consequence of having a blocked filter in the refrigeration system?

Having a blocked filter in a refrigeration system leads to increased energy consumption due to the added strain on the system. When the filter is obstructed, it restricts airflow and limits the circulation of refrigerant. As a result, the compressor has to work harder to maintain the desired temperature, leading to higher energy usage. This heightened demand results in the compressor running longer and possibly more frequently, which significantly contributes to increased operational costs and energy consumption.

In contrast, a blocked filter would not improve cooling efficiency, as the restricted flow would hinder the system's ability to effectively transfer heat. Additionally, it could potentially alter evaporating pressure, but typically it leads to lower pressure rather than an increase. Faster compressor cycling is also a consequence of an inefficient system, but primarily because of increased load rather than the specific impact of a blocked filter itself. Therefore, the most immediate and evident consequence is the increase in energy consumption.
