Abstract
A new method for defrosting a dehumidifier. The new method minimizes the formation of liquid 'slugs' which can occur during normal defrosting and which can damage the compressor, and also makes the operation of the dehumidifier more efficient. In the new method, defrosting takes place with the fan running to draw warm, room air over the condenser to warm the refrigerant passing through it in reverse, to thus minimize the formation of liquid 'slugs'. The warm air however is prevented by baffles from passing over the evaporator where it would undesirearably pick up moisture from the melting ice on the evaporator. An apparatus for carrying out the above method is also provided.
