THERM AirCon Units - 12V | 24V | 230VAC model

AirCon Units - 12V | 24V | 230VAC models 

The 3 air-conditioning models

THERM2200 model (12V model and 24V models)   -  Cooling only, suitable for smaller vehicles, good value, good performance

THERM2800 model (12V model and 24V models) -  Cooling only

THERM33000 model (230VAC) - Cooling and heating using full reverse Heat pump technology giving very efficient.

PTC heating, this is a conventional resistive heater like a toaster or hair dryer, it’s great for occasional use but offers no energy saving efficiency.

Heat pump, this is how all fridges / air conditioning work, they do not make heat or cold by direct means but “pump thermal energy (heat)” from a cold to hot or hot to cold air. If you ever used an air compressor you will feel the heat generated on the compressor cylinder. This is due to compressing the air volume and so pushing the compressed air temperature up. Also, when the air is stored in the air tank when you pump up your tyre the discharge nozzle filling the tyre gets cold. This is due to the expanding airs density being reduced and as such the temperature drops. This means that the heat or cold produced is not a direct result of the energy put into the compressor motor drive but in the compression or decompression of the gas. A fridge or air condition system simply does this in a sealed environment using a refrigerant gas/liquid for efficiency purposes. The efficiency of this process is reflected in the term COP or Coefficient of Performance. This number is usually about 2.8 which in layman’s terms means for every unit of power you put in you get about 2.8 units out. So, 1 kW of power will give about 3kW of heat. This 300% efficiency is why reverse heat pump tends to refer to a system where the heating / cooling can be reversed. I.e. the air conditioners can be reversed and become a heater, this makes for a very efficient low cost heating system.
