US Patent 12013152 Low-emissions heating, cooling and hot water system

The present disclosure provides a method for operating the hydronic system, which includes monitoring, by a control unit, a volume of hot water in a hot storage tank via a first set of flowmeters and a volume of chilled water in a cold storage tank via a set of second flowmeters. A first outlet temperature of the hot water is monitored by the control unit, via a first temperature sensor and a second outlet temperature of the chilled water via a second temperature sensor. A heat pump unit is operated by control unit, for recharging the hot water and the chilled water within the hot storage tank and the cold storage tank respectively. The heat pump unit is operated when a respective predetermined limit reaches for at least one of the volume of the hot water, the volume of the chilled water, the first outlet temperature and second outlet temperature.
