    Abstract: An energy efficient heat pump for a heating, ventilation, and air conditioning (HVAC) system includes a working fluid circuit and a first conduit of the working fluid circuit, where the first conduit extends between a first heat exchanger and a second heat exchanger of the working fluid circuit. The energy efficient heat pump also includes a compressor disposed along the working fluid circuit, where the compressor is configured to direct a working fluid along the working fluid circuit, and the compressor includes a suction port and an injection port. The energy efficient heat pump further includes an injection conduit extending from the first conduit to the injection port of the compressor, where the injection conduit includes an expansion device, and the injection conduit is configured to direct a portion of the working fluid from the working fluid circuit, through the expansion device, and to the injection port.

    Abstract: A thermostatic radiator valve supports a display that is configurable to display TRV information for a desired viewing direction to facilitate reading by a user, where the TRV comprises a configurable electronic display, a configuration circuit, and a processing device. The configuration circuit is capable of detecting when the TRV has been installed, determining a desired display orientation from a plurality of orientations with respect to a designated surface via a sensor in response to the detecting, and generating a display indicator indicative of the desired display orientation. The processing device is capable of receiving the display indicator and configuring the configurable electronic display to display the TRV information in the desired display orientation.

    Abstract: A process and apparatus for monitoring and/or controlling at least one air conditioning and/or heating plant (1) including a delivery line (3), a return line (4) and service lines (5) hydraulically interposed between the delivery line (3) and the return line (4), each service line (5) comprising at least one thermal exchange unit (7). The process detects a value (φ) of the flow rate of the carrier fluid traversing the thermal exchange unit (7), and determines a temperature difference (ΔT) between the temperature (Tt1) of the carrier fluid, at the first section (5a), detected at a first instant (t1), and the temperature (Tt2) of the carrier fluid, at the second section (5b), detected at a second instant (t2). The process determines a characteristic function which relates said temperature difference (ΔT) between the first and the second section to the carrier fluid flow rate (φ).

    Abstract: An air conditioner, a heating control method of an air conditioner, and a computer readable storage medium are provided. According to the method, a refrigerant passing through an evaporator is divided by a shunting module into two flows; one flow of the refrigerant is throttled and depressurized by an enhanced vapor injection electronic expansion valve. Based on a difference between an indoor pipe temperature and an exhaust temperature of a compressor of the air conditioner, an opening degree parameter of the enhanced vapor injection electronic expansion valve is controlled to control a refrigerant output amount by the enhanced vapor injection electronic expansion valve. Thus, the refrigerant amount of the flow of refrigerant, subject to throttling and depressurizing, for exchanging heat with the other flow of refrigerant can be controlled to implement an enhanced vapor injection function.

    Abstract: A heat exchanger for an air conditioner includes a plurality of flat heat transfer tubes through which a refrigerant flows; first and second headers disposed on opposite ends of the plurality of flat heat transfer tubes; at least one baffle disposed in at least one of the first and second headers and to partition an inner space of the at least one header; and a refrigerant flow control device disposed on the at least one baffle, to allow the refrigerant to selectively pass through the at least one baffle. The refrigerant flow control device is configured to prevent refrigerant from passing through the refrigerant flow control device when the refrigerant flows in one direction in the header, and to allow the refrigerant to pass through the refrigerant flow control device when the refrigerant flows in a direction opposite to the one direction in the header.
