MEXICOLDER REFRIGERATION RESULTS

Data collected on April 15th, in Mazatlan, Mexico, using a Xantrax Link 1000 Digital display, aboard Sailing Vessel “Pacific Raven”, Hunter model 40.5. Mexicolder evaporator installed in the freezer box, wall between freezer box and refrigerator box removed to allow cold air to circulate throughout. Other than the removal of the separating wall, the units are stock Hunter, 4” foam covered with a molded fibreglass surface. Note that gaskets on the sealing doors are due for replacement and are definitely leaking due to hardening. Upon replacement these recorded results should improve.

Day time: Recorded during the warmest part of the day, 1100-1600 Amp hours used during the 5 hours = 6.0 Average consumption during the period = 1.2 Amp hours per hour, or 15 Watt hours per hour Day-time average of 30 Amp hours per 24 hour day, or 360 Watt hours per 24 hour day Combined average is estimated at 27 Amp hours per 24 hour day, or 310 Watt hours per day

Night time:

Recording time 2200-

Hi Mike - the system appears to be working very well. Even though we are cooling a much larger area than before, the unit is running much less. I've attached some numbers that you may be interested in. Once the gaskets are replaced and also with the freezer boxes full of cold food I figure the numbers might even get a little better. The Nova Kool that was removed was using something in the order of 60 Amp hours per day, so the Mexicolder is consuming less than half. If this performance proves out during our cruising next winter we will be delighted. Thanks Mike

I'm heading back to Canada tomorrow, hope you have a good trip to the Sea, see you in October.
