A multi -function heating and cooling device, comprising components for an ambient air-coupled sorption heat pump cycle and vapor compression cooling cycle integrated together inside a single enclosure is proposed. The sorption heat pump portion is configured to provide very high heating efficiency, while the vapor compression portion is configured to provide high cooling efficiency. The evaporator coil for the sorption cycle and the condenser coil for the vapor compression cycle are configured to share a common ambient-air fan, saving space and cost. By combining the two heating-cooling systems into a single enclosure with shared components, the total installed cost and outdoor space required is reduced compared to installing separate heating and cooling systems.

An electronic expansion valve (EEV) is operated by a motor controlling a variable restriction valve in which a liquid refrigerant enters at a high pressure and exits at a reduced pressure. The motor controls the depth of a tapered needle which, as extended, penetrates multiple fixed orifices, aligned in series. Additional fixed orifices, downstream of the fully extended needle, provide further restriction and management of refrigerant flashing. Depending on the desired operating range, the following elements may be controlled: needle length, diameter, and taper; diameter, thickness, and relative elevation of each orifice; response and maximum torque provided by the motor; and geometry of the valve enclosed volume.

A method operates an absorption heat pump system, specifically the flow of hydronic cooling fluid through the condenser during system start-ups, or when the cooling fluid temperature is low. To minimize the time for an absorption heat pump to reach full cooling or heating capacity, it is desirable for the high side pressure to increase as fast as possible, and the low side pressure to decrease as fast as possible. Since the high side pressure is a function of the temperature of the refrigerant exiting the condenser, if the condenser cooling fluid temperature is low, the corresponding high side pressure will be low, which may not permit adequate working fluid flow rates from the high pressure side of the system to the low pressure side.
