Abstract
AN CONTROL ARRANGEMENT FOR A THERMAL STORAGE INSTALLATION INCLUDES VALVES 32, 34, 36 AND 38 WHICH CIRCULATE A LIQUID REFRIGERANT FROM A SURGE DRUM 14 EITHER VIA THERMAL STORAGE APPARATUS 10 AND/OR EVAPORATOR 12. ANY VAPOUR FORMED IN THIS CIRCUIT IS DRAWN OFF BY THE COMPRESSOR 16 AND RETURNED AS A LIQUID VIA CONDENSER 18, LIQUID RECEIVER 20 AND LIQUID CONTROL VALVE 14 TO THE SURGE DRUM 14.THERMAL STORAGE APPARATUS 10 IS CHARGED UNDER OFF-PEAK ELECTRICITY RATES TO ECONOMISE THE INSTALLATION. THE LEVEL OF THE REFRIGERANT LIQUID IS CONTROLLED BY THE SENSOR 26 OPERATING RETURN VALVE 24. IN ADDITION, THE CONDENSER 18 MAY BE CONNECTED WITH A FURTHER CIRCUIT UTILIZING THE SENSIBLE HEAT ANS STORING IT IN A HOT WATER STORAGE UNIT (SHOWN IN FIG. 2).THE THERMAL STORAGE APPARATUS 10 IS ALSO UTILISED IN A SEPARATE PHASE CHANGE MEDIUM CIRCUIT (SHOWN IN FIG. 3). IN AN ALTERNATIVE FORM, BOTH THE EVAPORATOR 12 AND THERMAL STORAGE APPARATUS 10 CAN BE OPERATED SEPARATELY IN PARALLEL, IN PARTICULAR IN AN OFF-PEAK MODE. THE ARRANGEMENT WHEN USING R22 AS PRIMARY REFRIGERANT OPERATES IN THE HEAD PRESSURE RANGE OF 1090-1590KPA (159-230PSI) AND A SUCTION PRESSURE RANGE OF 277-346KPA (40-50PSI) RESULTING IN SUBSTANTIAL ENERGY SAVINGS (20).
