<p>A heat pump using a zeotropic refrigerant includes a main circuit for a refrigeration cycle, which is connected with a closed circuit consisting of a rectification distillation apparatus, a cooling apparatus and a reservoir connected through switch valves. The switch valves are controlled according to the detected magnitude of the load, and the refrigerant composition for the main circuit is appropriately adjusted according to the state of the load, thus controlling the performance of the heat pump.</p> |
