ABSTRACT:
In a heat pump having a heat source, a heat sink and a thermal storage heat exchanger in which heat energy is cyclically accumulated and discharged by circulation of a secondary refrigerant therethrough, the improvement wherein: the secondary refrigerant is an aqueous solution having a concentration which is below its eutetic concentration, the heat sink is adapted to super cool the aqueous solution to partially freeze it to generate a partially frozen solution in which fine ice particles are retained in suspension, the thermal storage heat exchanger has a storage chamber, a first input communicating with said storage chamber for admitting said partially frozen solution from the heat sink to said storage chamber, a second input communicating with said storage chamber for admitting heated refrigerant from the heat source sink to said storage chamber, a first output communicating with said storage chamber for discharging liquid phase refrigerant from said storage chamber for circulation to said heat sink and/or said heat source.
