ICEcold 1

Has anyone used the refrigerant additive ICE cold? I've received glowing sales brochures, but do not know anyone whom has tried it. Sales lit speaks of 20-28% increased efficiency.

here is a link;

it appears that the efficency is in heat transfere, which really doesn't change the energy input into the AC unit. It just allows your AC cool off faster with an equal amount of input energy.

I've read the links, just haven't found anyone who has used it, and knows what they are doing. Does dropping the boiling point of the refrigerant also drop capacity? Has there been any problem with coil freezing? Lots of people recommend products, but would not use it themselves. Just wondering if anyone has tested these claims. The lessening of transfer resistance seems it should have some impact on the control. I'm a doubtful thomas.

dropping the boiling of a refrigerent will change the characteristics of the compressor and evaporator along with the condensor. Thats why each refrigeration machine asks what refrigerant you want and what temperature in the evaporator you need.

energy is energy, snake oil cannot create it from nothing.

Let's look at it step by step.
Under static conditions, an increase in heat transfer rate will mean that the length of the flooded portion of the evaporator will be less. The length of the superheat section will be correspondingly greater. More super heat.
More super heat will tend to open the control valve to restore the superheat to the set point.
Possible result: Greater refrigerant flow, slightly higher back pressure, more BTUs of cooling, more load on the motor.
This may be a quick and economical way to slightly increase the capacity of a system if site conditions indicate that the motor is capable of taking more load. Consider not only normal load but cool down load also.
