frostles heat pump

[US Iceman]

Air-source heat pumps were being sold in very large quantities many years ago. After the first full year almost everyone I knew who had one complained of cold air blowing during the winter.

I suspect one of the problems is the limited coil surface used on the outside coil. Smaller coils would require lower evaporating temperatures. The lower evaporating temperatures increase the potential for frost formation, which is dependent on the air dewpoint temperature.

If the heat pump was operating at -22C, then this is not that much different than a refrigeration system that is used for a walk-in freezer.

LC, who was the manufacturer of this heat pump?

I'm one of them.
