Obviously there are a myriad of ways to improve efficiency of your cold store. However listed below are some simple common sense examples which most of the time could be considered as good house keeping. We will also touch on some more technical aspects.
Check your access systems
Doors that are left open longer than necessary will let in warm air and increase costs. Check your access systems to ensure doors close promptly. Also, are procedures in place that limit any unnecessary traffic entering and leaving.
Limit Heat Loads
Switch to lower wattage LED lighting with sensors. Not only will this save electricity at the front end, it will also reduce heat loads in the area. Sensors which turn off unnecessary lighting will also help.
Another piece of equipment that uses large amounts of electricity are evaporators (coolers). Because these run below freezing, they need electric heaters to periodically clear the ice that builds up on the cooler face.
This is called a defrost cycle, and optimal settings of the heater interval and defrost duration times will not only keep you coolers clear of ice, making operation more efficient, but will also save electricity costs.
Make Sure all your Plant is Clean and Tidy
Keeping your cooling equipment clean will improve its efficiency. Condenser coils that the plant uses to exchange the energy from the cold store to atmosphere need to be kept clean. Similarly, internal coolers should be kept clean to maximise efficiency.
Is Your Plant in Good Running Order?
In the same way that good housekeeping can improve your plants efficiency, regular servicing by a specialist can also help.
Typically refrigeration systems should be checked for correct operation, as well as refrigerant leaks that can be expensive in terms of replacement, damage or reduced efficiencies.
Further consequences of servicing neglect include breakdowns leading to loss which could be avoided.
