<p>The air conditioning system is especially for small flats or bungalows and by allowing heat from the expelled air to warm cold, fresh incoming air the energy consumption of the system is reduced. Pairs of adjacent inlet and outlet ducts are attached to a large volume heat exchanger chamber, the pair communicating with the external air motor driven fans. The heat exchanger chamber contains a pair of perforated metal plates held parallel with a spacing of about five millimeters by spacer blocks. Thd perforations allow a large air flow.</p> |
