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 a 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 adapted to receive said partially frozen solution from the heat sink and to separate the ice particles from the liquid phase refrigerant to form a porous ice bed and a substantially ice free liquid bath, and wherein the thermal storage heat exchanger is adapted to receive heated refrigerant and to discharge the heated refrigerant into said chamber such that it is placed in intimate contact with the ice bed in a manner such that it may pass through the pores of the porous ice bed prior to its return to the bath.
