摘要： A heat-activated fluid pump heats and cools a building. For cooling, an evaporator, coupled to a solar heater or comprising multi-pane windows with solar radiation-absorbent areas thermally coupled to a fluid cavity, converts a working fluid into a vapor. A pressure control valve allows vaporized working fluid into a liquid-piston chamber whenever a target pressure in the evaporator is exceeded. The working fluid expands, displacing liquid from the liquid-piston chamber in a pump stage where it enters a condenser situated in a vertical hole or covered horizontal trench in the ground. Ground-temperature pumped fluid returning to the liquid-piston chamber in a suction stage passes along the way through coils in rooms of the building. Check valves allow replenishment of the evaporator with return working fluid and direct flow of pumped fluid into and out of the liquid-piston chamber. For heating, the evaporator is in the ground.

摘要： A heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a heating fluid circuit, a cooling fluid circuit, and a storage fluid circuit. A thermal system of the HVACR system absorbs energy from the storage fluid circuit and rejects it to the heating fluid circuit. The storage fluid circuit includes thermal storage tanks containing thermal storage material that can provide energy for heating or absorb energy for cooling depending on the state of the thermal storage material. Heating can be provided using the heating fluid circuit and the heat provided by the thermal system. Cooling can be provided using the cooling fluid circuit by absorbing energy from the conditioned space using a cooling fluid and rejecting energy from the cooling fluid to the storage fluid circuit. The thermal storage tanks can have heat added to them using an air source heat pump system to support heating operations.

摘要： Photovoltaics and an MPPT DC/DC converter powers a DC bus of a controller. It uses an electric heat pump to heat a mass like water, and also has a resistive heating element to heat the mass. A microcontroller controls a variable frequency (VFD) motor drive to power the electric heat pump when sufficient solar power is available to run the heat pump and uses the resistive element to heat the thermal mass when insufficient solar power exists for the heat pump or when excess solar power is available. A controller has an MPPT input for solar power and a VFD to provide power through an output to a heat pump-based water heater and an output to power a resistive water heating element. A microcontroller determines solar power available and runs the heat pump when possible and the resistive element when insufficient power is available or when excess power is available.
