We've been living aboard while the renovations are being done at our house. Our food has been stored in a large ice chest since our onboard refrigeration system has been out of commission. So, it's been a little more like camping than boating lately.
About the New Unit
Our new SeaFrost refrigeration unit is primarily an air-cooled 12-volt unit but it has the capability of using supplemental water cooling at some point in the future. The compressor is a Danfoss BD-50 with variable speed capability. (Most marine refrigeration systems use Danfoss compressors.)
I had to remove an AC receptacle from the galley area to make space for
the new electronic controls for the refrigerator. This proved to be interesting
since it was not controlled by a switch on the AC panel.
The Installation in Pictures
|With the condenser/compressor box simply sitting in place, the copper tubing |
was routed from the evaporator plate in the ice box to the
compressor. Six feet of tubing was required.
|With the copper tubing installed and insulated, the wiring was done. The white cable |
provides power while the blue cable is a data cable for the controls.
|The completed installation of the condenser/compressor in the forward area under |
the quarter berth. The big gray hose on the left is the cooling air discharge into the cabin.
|The refrigerator control panel is used to control the evaporator plate temperature |
as well as the ice box temperature and compressor speed.
|Within minutes of starting, the new evaporator plate begins to frost up, starting at the |
bottom. The new evaporator plate is a lot thinner than the old cold plate.
|Food chilling in the new refrigerator system. The cost of the new refrigerator |
system, including installation was about $2500.
