摘要： Methods, systems and apparatuses are directed to a capacity modulating assembly configured to distribute two-phase refrigerant mixture to an evaporator of a HVAC system, such as a micro-channel heat exchanger (MCHEX) evaporator. The capacity modulating assembly may include a plurality of expansion devices. During capacity modulation, at least one of the plurality of expansion devices can be closed so that a refrigerant flow rate through the remaining expansion devices can be maintained. The capacity modulating assembly can include a refrigerant outflow port, which may help direct refrigerant out of the heat exchanger. The capacity modulating assembly can be connected with the MCHEX. The plurality of expansion devices can be configured to extend inside a header of the MCHEX to help distribute refrigerant to the micro-channel tubes of the MCHEX.

摘要： A condensate drain device includes an elongate base having a first end, a second end and side edges extending between the first and second ends; a plurality of teeth extending away from a side edge of the base; and a lip formed on the side edge of the base opposite from the teeth. Each tooth includes a free end and two side edges. The condensate drain device is configured to be attached to a microchannel coil to collect condensate including a plurality of tubes and a plurality of fins coupled to the tubes, with each tooth being received in a space formed between two adjacent fins.

摘要： Embodiments of a refrigerant distributor for a micro-channel heat exchanger (MCHEX) are described. The refrigerant distributor may be configured to have orifices and/or a flow valve that are inside a header of the MCHEX. The MCHEX can be used as an evaporator in a cooling cycle, where refrigerant is distributed into the header(s) through the orifices and the flow valve may be generally in a closed state that generally prevents a refrigerant flow through the flow valve. In a heating cycle, the flow valve of the refrigerant distributor may be configured to be in an open state that allows the refrigerant to flow into the refrigerant distributor and to be directed out of the MCHEX through the refrigerant distributor. In some embodiments, the refrigerant distributor may be configured to receive liquid refrigerant, so as to eliminate the need of an expansion valve in a HVAC system.

摘要： Heat pump systems and methods for providing chilled/hot liquid for air-conditioning and domestic hot-water, are provided. The heat pump systems include a first heat exchanger, a second heat exchanger and a third heat exchanger (e.g., a hot-water heat exchanger) that share at least one expansion valve disposed at a downstream position of the hot-water heat exchanger. The at least one expansion valve is disposed between the hot-water heat exchanger and the first and second heat exchangers. The heat pump systems can provide six operation modes, including a cooling mode, a heating mode, a water-heating mode, a heat-recovery mode, a simultaneous heating and water heating mode, and a defrost mode.
