This idea works like magic. If you put the compressor inside the drying airspace, it will add its heat to the process. The clothes will absorb this heat and dry faster. As a general rule, the refrigeration process gets more efficient as temperature rises, due to the higher system pressures. The ambient air also holds more water per cubic foot.

Another idea to consider, especially if utilizing solar heat, is desiccant dehumidification. In an arid or hot climate, this idea has been proven to work well. There have been a number of model homes built that use a "desiccant waterfall" to dehumidify the entire living space.
