For example, power supply at the shed may be limited, or a solar power installation may be planned, in which case an ice bank storage system could be the best solution. In detailed consultation with Dairycool, farmers are presented with tailored options based on the current farm compliance level, future goals and budgetary requirements.” Refrigerant load and type is another key consideration but can be di cult to understand. “In basic terms, think of the refrigerant in your milk cooling system as being like oil owing through a tractor engine. As long as the ‘oil’ stays within the system, everything is good. Regular maintenance is key here. In an under sized or poorly maintained older unit with high hours, leakage becomes more likely. Total loss can be catastrophic to the system. In addition, older systems are more costly to run due to their lower Energy E ciency Ratio (EER).” This older ‘oil’ (HFC refrigerant such as R404a) is damaging to the environment and heavily taxed, so the cost to keep topping it up and repairing leaks becomes prohibitive. This is where a decision needs to be made: • Change the ‘oil’ to a less damaging HFC gas that can reduce potential emissions from leaks by up to 50%. For a correctly sized system in good condition this may be a viable medium-term solution. • Or upgrade the ‘tractor’ to a modern system, achieving higher EERs, have added features such as heat recovery and remote monitoring, and run on new generation refrigerants with an 80%+ reduction in emission potential and less prone to leakage.
