摘要： Methods and systems to manage refrigerant levels in a chiller system are provided. An evaporator of the chiller system may be configured to have a spill over port allowing oil containing refrigerant to spill over through the spill over port. The spill over port may be positioned at a place that corresponds to a desired refrigerant level in the evaporator. The spill over refrigerant may be directed into a heat exchanger that is configured to substantially vaporize refrigerant of the spill over refrigerant to a slightly superheat temperature. A method of maintaining a proper refrigerant level in the evaporator may include regulating a refrigerant flow to the evaporator so that the vaporized refrigerant of the spill over refrigerant is maintained at the slightly superheat temperature.

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： Controls for chillers with variable speed and variable geometry compressors are disclosed. In exemplary embodiments, a centrifugal compressor equipped with a variable frequency drive and variable inlet guide vanes may be utilized. A controller is operable to determine a chiller capacity command, a speed command, and a vane position command. The speed command and vane position command may maintain system operation at or near a surge control boundary over one or more capacity ranges to enhance efficiency and deviate from the surge control boundary over certain capacity ranges to improve controllability or avoid control aberrations.

摘要： A vibration isolation apparatus for an air conditioning system may include a flow passage, at least a portion of which has a convoluted structure. The flow passage may also be coupled to two stabilizing members. The vibration isolation apparatus may include a structural supporting member to retain the two stabilizing members. The rod may be isolated from the stabilizing members by vibration isolation members. The vibration isolation apparatus may be positioned in a refrigeration line between an outlet of a compressor and a refrigerant pipe. The stabilizing members, the convoluted flow passage and the vibration isolation members may attenuate the vibration generated by the compressor so as to reduce the vibration transmitted to the refrigerant pipe. The structural supporting member may enhance the structural strength of the vibration isolation apparatus to withstand the pressure of the compressed refrigerant.
