Abstract: A chiller system includes a mechanical-cooling circuit configured to circulate a refrigerant through an evaporator of the mechanical-cooling circuit, where the evaporator is configured to cool a conditioning fluid with the refrigerant. The chiller system also includes a free-cooling circuit configured to circulate the refrigerant through a heat exchanger of the free-cooling circuit, where the heat exchanger is configured to cool the conditioning fluid with the refrigerant. The chiller system also includes a distribution header having a first inlet configured to receive the refrigerant from the mechanical-cooling circuit, a second inlet configured to receive the refrigerant from the free-cooling circuit, and an internal volume fluidly coupled to the first inlet and the second inlet. A fan coil unit of the chiller system is configured to receive the refrigerant from the internal volume of the distribution header.

Abstract: The present disclosure relates to an oil flow switch, comprising a float device connected to a circulating oil passage and a floating liquid level switch element provided in the float device, wherein the float device comprises an oil inlet, an oil outlet, and a float chamber provided between the oil inlet and the oil outlet, the floating liquid level switch element is provided in the float chamber, and the float device is provided with a channel in communication with the float chamber. The oil flow switch according to the present disclosure may avoid a false alarm of the oil level switch and meanwhile mitigate disturbance to the float caused by liquid level fluctuation to reduce friction between the float and the sleeve rod. Further, a lubrication system with the above oil.
