A refrigerant recovery device comprising a pump; a heat rejecting heat exchanger disposed in fluid communication with the pump; a refrigerant storage container disposed in fluid communication with the heat rejecting heat exchanger and the pump; a fluid interface disposed in fluid communication with the pump and configured for fluidly connecting the refrigerant recovery device to a refrigerant containing device; and a plurality of valves disposed in fluid communication with at least one of the pump, the heat rejecting heat exchanger, the refrigerant storage container, or the fluid interface and configurable to establish a first fluid pathway fluidly connecting the refrigerant containing device to the refrigerant storage container, and a second fluid pathway fluidly connecting the heat rejecting heat exchanger to the refrigerant storage container.

A purge system for removing non-condensables from a chiller system includes a purge chamber, a plurality of carbon beds fluidly connected to the purge chamber into which a flow of refrigerant and non-condensables is selectably directed from the purge chamber to remove the non-condensables therefrom. A vent line is fluidly connected to the plurality of carbon beds to dispose of the collected non-condensables, and a heater is operably connected to the plurality of carbon beds to selectably heat one or more of the carbon beds of the plurality of carbon beds to release refrigerant therefrom and direct the released refrigerant to the purge chamber.

Efficiency in refrigerant charging work is addressed when a recovered refrigerant recovered from a first heat source unit is to be charged to a second heat source unit. A refrigerant charging method is a charging method used when a first heat source unit of an already installed refrigeration cycle apparatus in which a refrigeration cycle is to be performed by a refrigerant that circulates is to be replaced with a second heat source unit. The refrigerant charging method includes recovering a first refrigerant from an already installed refrigeration cycle apparatus and obtaining a recovered refrigerant and charging the recovered refrigerant and charging a second refrigerant whose composition differs from the composition of the recovered refrigerant to the refrigeration cycle apparatus after renewal that includes the second heat source unit.

Efficiency in refrigerant charging work is addressed when a refrigerant recovered from the first heat source unit is to be charged to a second heat source unit. In a refrigerant charging method in which a first heat source unit of an already installed refrigeration cycle apparatus in which a refrigeration cycle is to be performed by a refrigerant that circulates is replaced with a second heat source unit, transferring the refrigerant from the first heat source unit to the second heat source unit is included. In addition, the method includes measuring the weight of the refrigerant that is transferred from the first heat source unit to the second heat source unit.

A system attachable to a refrigeration circuit includes a recovery pump attachable to the refrigeration circuit to remove refrigerant. The recovery pump includes a pump, an electric motor, a battery pack, and a recovery pump controller for controlling the operation of the electric motor. The recovery pump controller has a first communication interface. The system further includes an accessory attachable to the refrigeration circuit concurrently with the recovery pump. The accessory includes a sensor for detecting a characteristic value of the refrigeration circuit, and an accessory controller electrically connected with the sensor to receive a signal corresponding with the characteristic value of the refrigeration circuit. The accessory controller has a second communication interface to communicate the signal to the recovery pump controller via the first and second wireless interfaces. The recovery pump controller controls the operation of the electric motor based upon the signal received from the accessory.
