Abstract: There is provided a gas replacement technique for an expander (14) of a cryocooler (10) for avoiding contact between electrical equipment in the expander (14) and a flammable gas. A gas replacement method for an expander (14) of a cryocooler (10) is provided. The expander (14) includes an expander cylinder (16), a pressure switching valve (42) that switches a pressure inside the expander cylinder (16), a connection flow path (20b) from the pressure switching valve (42) to the expander cylinder (16), and an expander motor (40) that drives the pressure switching valve (42). The method includes connecting a nonflammable gas source (60) to the connection flow path (20b) or the expander cylinder (16), and purging a residual gas in the expander cylinder (16) with a nonflammable gas from the nonflammable gas source (60) while the expander motor (40) is stopped.

Abstract: A method for assessing an efficiency of a chiller. The method includes: performing, using a processor of a computer system, an energy balance check on operational data of a chiller in a chiller group; selecting, using the processor and based on the energy balance check, a reference chiller from one or more other chillers in the chiller group, wherein an energy flow of the reference chiller has a best energy balance amongst the one or more other chillers; determining, using the processor and reference operational data from the reference chiller, the efficiency of the chiller; and performing, based on the determined efficiency of the chiller, an action with respect to a chiller plant containing the chiller. Other aspects are described and claimed.

Abstract: A heat pump system comprises: an outdoor unit (1), a plurality of indoor units (491, 492, 493, 494), one or more valve modules (31, 32), a plurality of sensors and a control device. The control device is connected to the plurality of sensors, and configured to execute a local cut-off step upon receiving a signal indicating refrigerant leakage in a corresponding indoor unit (1) sent from any sensor, the local cut-off step comprising: closing the indoor unit throttling element (404, 414) of the indoor unit (491, 492, 493, 494) with leakage; and closing the corresponding branch control valve (531, 533) in the valve module (31, 32) connected to the indoor unit (491, 492, 493, 494) with leakage. The heat pump system can effectively prevent continuous refrigerant leakage into the room, and have minimal impact on other indoor units (491, 492, 493, 494) of the heat pump system.
