Peltier conductors are small, neat and compact so the dehumidifiers are much smaller than the other types, plus as they don’t use compressors or heating elements and only very small fans the electrical consumption of Peltier driers is a fraction of that used by refrigeration dehumidifiers.

It is important to realise that the release of moisture vapour pressure within a dwelling to avoid condensation does not require a specific ventilation rate. Not only would that increase the size of the unit to something totally unmanageable, it would also send the energy consumption through the roof. They are also more eco-friendly as they don’t require any refrigerants, which are integral to how compressor dehumidifiers work. An alternative design senses the impeded airflow and shuts off the cooling coils in a similar manner.The cold evaporator coil of the refrigeration device condenses the water, which is removed, and then the air is reheated by the condenser coil. If you are looking for a dehumidifier then you’d be better off making your decision based on the airflow rate, power consumption and extraction rates to identify the most suitable unit. The reason for the limited acceptance of desiccant dehumidification can be attributed to initial installation costs, the fact that operational benefits are not fully understood, lack of technology awareness, and company priorities, which are not focused on benefits of new technology.

Now, because those hygroscopic materials can only absorb so much moisture before they become saturated and ineffective, desiccant dehumidifiers use thermal energy to regenerate (dry out) the silica or lithium chloride. If you do come across this be warned that it isn’t an accurate way to compare to compare them to other types of dehumidifier. What makes them so good for these types of environments is the silent operation and low power consumption, so you can leave them running and just let them get on with things and whereas they’re not great for eliminating problem condensation in an entire house, they’ll easily help with the moisture in a pair of shoes that’s been worn all day (and therefore help limit the associated ‘aroma’). Because of the lack of compressor parts, desiccant dehumidifiers are often lighter and quieter than compressor dehumidifiers. Also, some air conditioner types spray any collected condensate onto the exterior condenser coils to cool it by evaporation, improving overall efficiency.The Passyfier Core 100 Vent is a through-the-wall Core Dehumidifier Vent capable of transmitting up to 1 Litre of water vapour per 24 hours.
