摘要： An air pressure differential sensing system includes a conduit defining an air passage through which air flows upon application of an air pressure differential across different regions of the air passage, a flap pivotally connected to the conduit, and a sensing device mounted proximate to the air passage and separate from the flap. The flap is configured to move about a pivotal axis in response to the air flowing through the air passage. The sensing device is configured to sense an angular position of the flap about the pivotal axis, the angular position of the flap being a function of the air pressure differential.

摘要： Methods of controlling a cooling unit and embodiments of a cooling unit are disclosed. A method of improving efficiency of the cooling unit includes detecting a degree of opening of a hot gas bypass valve configured to divert a portion of coolant from a compressor to a heat exchanger of the cooling unit, and adjusting a condenser discharge pressure based on the detected degree of opening. Aspects may increase cooling efficiency at partial cooling requirements. Fluctuations in refrigerant pressure at low cooling capacities and condenser medium inlet temperature may be avoided. Minimum condenser water inlet temperature for a water-cooled cooling unit may also be reduced.
