CARAVAN AND MOTORHOME ELECTRICAL POWER USAGE COSTS?
I have installed an Energy meter in my caravan. Only skilled electrical people should do this.
This meter measures: W, Kwh, A, V, PF, Htz, and can be zeroed .
When there is a power cut it remembers the readings when power is restored. I therefore know exactly what my electrical usage is.
Ironically, campervans can come with compressor fridges which are:
1. Far cheaper than 3-way
2. Can maintain their set temperature in even the most extreme ambient temperatures. My 65 litre portable is designed to cope with Australian temperatures and for the beach as it runs of 240V and 12V. AND it can maintain -22oC in the freezer section! Yes, that is a minus in front!!!
3. Far cheaper to run as they are more efficient.
4. The noise level is low and can be suppressed. If they are ok for campervans…….
5. 3-way fridges struggle and are only capable of keeping the temperature some 20oC or so below ambient, so watch out for food spoiling. Compressor fridges do not suffer this problem because of how they work.
ANSWER
Manufacturers should and could fit 12v compressor fridges because:
a. Saves on energy/running costs and the planet……
b. The cost saving using compressor fridges could allow:
a. More solar panels to be fitted.
b. Lithium batteries to be installed. They are now becoming financially attractive.
c. The above would then allow off-grid running of the fridge on 12v electricity even in transit.
d. Ambient temperatures are rising significantly.
QUESTION?
Why have manufacturers not addressed this, especially as more sites are charging for electricity at silly rates????
They could start by doing this initially on top of the range models.
Then demand would force them to introduce it to all models.
QED (For the mathematicians) out there.
