Abstract: 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.

Abstract: A system and method for controlling a system that includes a variable speed compressor are described. The method can provide improved accuracy in the control of a system, for example, a heating, ventilating, and air condition (HVAC) system that includes a variable speed compressor, and can reduce a compressor cycling frequency of the compressor when a required capacity is below a minimum capacity of the compressor.

Abstract: A system and method for cooling power electronics using heat sinks, and including a heat pump. The heat pump includes a main refrigerant circuit having a compressor, an indoor heat exchanger, and an outdoor heat exchanger, and a reversing valve. A biflow expansion valve is configured to receive condensed liquid refrigerant and to expand the refrigerant. A cooling circuit in fluid communication with the main refrigerant line includes an expansion device configured to receive a portion of condensed liquid refrigerant from the main refrigerant circuit and to expand the portion of condensed liquid refrigerant. A heat sink is configured to receive the expanded portion of refrigerant from the expansion device. Power electronics are coupled to the heat sink such that the portion of expanded refrigerant from the expansion device passes through the heat sink and cools the power electronics.

Abstract: Method and system for controlling a compressor and a supply fan in a heating, ventilating and air conditioning (HVAC) system are disclosed. The system includes a compressor having a startup state and a running state, a supply fan, and a controller configured to control the compressor and the supply fan in the HVAC system. The compressor and the supply fan are controlled based on a dehumidification map and/or an efficiency map. The system also includes a cooling coil configured to receive a fluid in heat exchange relationship with refrigerant from an evaporator to cool air. The supply fan is configured to deliver the cooled air from the cooling coil to a conditioned space as supply air.
