Description
Added fresh water cooling option must be order at time of original system configuration.
Fresh Water Cooling Option:
Uses a different cooling coil than the standard coil-must be designated at time of system configuration, can not be added to the standard system after it has been configured.
OzeFridge approaches the use of water cooling of the refrigerant gas condenser differently than other systems on the market, which contributes to the industry leading technical design and efficiency. First, it’s important to note that the water cooling on OzeFridge units is done by Fresh Water from your ships water tank rather than dealing with the corrosive nature of sea water! Right away, the No 1 maintenance issue with a water cooled refrigerant condenser goes away, and that is fouling and scaling of the raw water heat exchanger.
Using the ships fresh water tank for condenser cooling raises two common questions:
1) Will it make my tank water hot?
2) Is there a risk of contaminating my tank water?
1- To address warming your tank water, the BTUs of heat being transferred to your tank water are minimal and in tanks over 10Gallons, you won’t even notice a warming of the fresh water.
2- In terms of the risk of Fresh Water Contamination, the configuration of the fresh water cooling loop on the condenser eliminates the risk of Refrigerant Gas to Water contamination. The Water Loop on the condenser is also high quality and food safe.
A second important feature of the OzeFridge fresh water cooling feature is it’s control.
On systems equipped with Fresh Water Cooling, it only turns on when the Condensing unit reaches 110 degs F or higher.
So energy is not used when it’s not needed.
Concerning Energy, the ultra low amp draw micro-pump, only uses 0.5 Amp-Hours or power to the overall daily power usage, but that is off-set by the 1.0Amp-Hours of overall energy savings of the compressor. So adding the fresh water cooling option, can actually use Less Daily Power when the compressor unit is operating in Hot or Enclosed spaces without good dissipation of condenser heat.
Lastly and something to consider first, would be to understand why and when the Ozefridge system would benefit from adding fresh water cooling. Which is, when the compressor unit is going to be mounted in an enclosed space without the ability to have adequate exchange of the space air.
