Abstract
A combined heating and cooling system for a building is described. The system includes a heating circuit and a cooling circuit. The circuits are coupled to heat energy storage reservoirs. Each reservoir defines an elongate flow path along which water can flow in the form of a column. Using heat from the heating circuit, one or more of the reservoirs can be charged with hot water which is stored in the reservoir(s). The stored hot water is subsequently used to boost the temperature in the heating circuit. Similarly, water cooled by the cooling circuit can be stored in other reservoir(s) for subsequent use in boosting the cooling action of the cooling circuit. A heating system or a cooling system may also be provided.

In a building having a heating load and a cooling load, a heating and cooling system comprising:
- a cooling circuit for a cooling fluid;
- means in said circuit for cooling said fluid by removing heat energy therefrom;
- means for circulating said cooling fluid unidirectionally in said cooling circuit;
- the building cooling load being connectible in said cooling circuit downstream of said cooling means so that said cooling fluid can be passed through the building cooling load;
- a first heat energy storage reservoir containing a fluid, the reservoir comprising a tank having therein a plurality of upright baffles disposed in spaced, generally parallel positions, each baffle extending from the bottom of the tank to a position above the level of the fluid, and from an upright wall of the tank to a position spaced from an opposite upright wall so that the baffles together define an elongate fluid flow path of serpentine form along which the fluid can flow in the form of a column in a generally horizontal direction, the tank having an inlet connection communicating with one end of said path and an outlet connection communicating with the opposite end of said path;
- first heat exchange means coupled in said cooling circuit downstream of the building cooling load;
- means for coupling said first heat exchange means with said inlet and outlet connections of said first heat energy storage reservoir so that heat energy can be transferred between said fluid in the first heat energy storage reservoir and said cooling fluid;
- means for displacing said fluid in the first heat energy storage reservoir along said elongate flow path of the reservoir and through the heat exchange means;
- a heating circuit for a heating fluid;
- means in said heating circuit for retrieving said heat energy removed from the cooling liquid by said cooling means and for transferring said heat energy to the heating fluid;
- said building heating load being connectible in said heating circuit downstream of said heat retrieving means;
- means for circulating said heating fluid unidirectionally in said heating circuit;
- a second heat energy storage reservoir containing a fluid, the reservoir comprising a tank having therein a plurality of upright baffles disposed in spaced, generally parallel positions, each baffle extending from the bottom of the tank to a position above the level of the fluid, and from an upright wall of the tank to a position spaced from an opposite upright wall so that the baffles together define an elongate fluid flow path of serpentine form along which the fluid can flow in the form of a column in a generally horizontal direction, the tank having an inlet connection communicating with one end of said path and an outlet connection communicating with the opposite end of said path;
- second heat exchange means coupled in said heating circuit downstream of the building heating load;
- means for coupling said second heat exchange means with said inlet and outlet connections of said second heat energy storage reservoir so that heat energy can be transferred between said fluid in the second heat energy storage reservoir and said heating fluid;
- means for displacing said fluid in the second heat energy storage reservoir along said elongate flow path of the reservoir and through said second heat exchange means;
- whereby, with the building cooling load disconnected from said cooling circuit and said cooling means in operation, heat energy can be transferred from the fluid in said first heat energy storage reservoir to said cooling fluid and said first energy storage reservoir can be charged with cooled fluid, said fluid being stored in the first reservoir until the building cooling load is connected in said cooling circuit, whereupon the stored cooled fluid can be returned to the first heat exchange means to cool said cooling fluid in the cooling circuit and compensate at least in part for the increase in temperature of the fluid which occurs due to passage of the fluid through the building cooling load, operation of said cooling means serving to simultaneously heat said heating liquid in said heating circuit by way of said heat energy retrieving means, whereby with the heating load disconnected from said heating circuit, heat energy can be transferred from said heating fluid to the fluid in said second heat energy storage reservoir and said second heat energy storage reservoir can be charged with heated fluid, said fluid being stored in the said second reservoir until the building heating load is connected in said heating circuit, whereupon the stored heated fluid can be returned to said second heat exchange means to heat said heating fluid and compensate at least in part the reduction in temperature of the fluid which occurs due to passage of the fluid through the building heating load.
