Air conditioning in certain geographical locations would be advantageous. Unfortunately traditional air conditioning depends upon refrigeration systems for air cooling. To avoid the fuel costs and the complexity of refrigeration systems a dew point heat exchanger can be utilised. The heat exchanger comprises a number of thermally conductive layers to define dry paths and wet paths adjacent to each other. Inlet air flow into a dry path is cooled by heat exchange with adjacent wet paths through the thermally conductive layer. A proportion of the inlet air flow is diverted to the wet path such that evaporation through the latent heat of evaporation causes cooling of the air flow whilst the remainder of the inlet air flow is presented to a manifold for utilisation with regard to air conditioning. It will be understood that the relative humidity between the inlet air flow and the wet path is important. In such circumstances utilisation of a dehumidifier either independently or as part of an air conditioning arrangement will facilitate operation.
