reverse cycle air conditioning

Any time Johny. It will be interesting experience to me too. The good thing about re designing the portable A/C is the system will be of a sealed type. No connectors no rubber hoses. It will be specifically designed for the vehicle so any possibility of gas escaping the system will be eliminated as ...

!5 even 20% more power to the motor?! You beauty! Having in mind that I will most likely go for Direct Drive and lighter by 20 kg than the originally planned for the conversion motor what is some 20-30 kilos in inductors and capacitors? We must admit that 35% of the weight of the inverter in additio...
