<p>This invention provides a combined heating and cooling apparatus utilising the heat pump to transfer exhaust heat from a cooling circuit and utilise this heat in the heating circuit. Control means may be provided such that when either the cooling circuit or heating circuit have achieved a suitable temperature, alternative heat exchangers can be brought into the circuit in alternative to the primary cooling or heating means. The distillation apparatus using such a combined heating and cooling apparatus is also provided.</p> |
