A refrigerant management system is interchangeably connectable to a plurality of refrigeration systems and can manage one or more connected refrigeration systems. The refrigerant management system includes a portable system housing for securing various components in a self-contained unit. The refrigerant management system includes a work panel that can be arranged on the top of the system housing. The work panel includes various operational efficiency improvement devices that allow a user to use, store and organize various movable items that would otherwise be carried separately from the refrigerant management system.

A servicing device and method for operating a servicing device for vehicle air-conditioning systems in particular for the self-cleaning thereof, the servicing device is equipped with an emptying device and a filling device for the drawing off of the refrigerant/compressor oil mixture from the refrigerant circuit system of a vehicle air-conditioning system and for the refilling of the vehicle air-conditioning system with refrigerant and compressor oil. A vacuum pump is used for the residual emptying of the refrigerant circuit system of the vehicle air-conditioning system and/or of the servicing device. An at least partially evacuated flushing agent tank is connected directly or indirectly via a connecting line with at least one of the high pressure servicing connection connectors of the servicing device and/or the subsequent pressure hoses and/or the switchover valve block and that a fluidic further connection takes place to the refrigerant reservoir which is under increased refrigerant pressure.

A refrigerant recovery and recharge device and a method to recharge oil to refrigeration equipment is disclosed. The refrigerant recovery and recharge device comprises a valve block which is adapted to establish fluid communication between the device and refrigeration equipment and a recharge path adapted to recharge oil to the refrigeration equipment through an outlet in the valve block. The device further comprises at least a first oil container and a second oil container and the valve block comprises a valve with a first inlet and a second inlet. The first oil container is in fluid communication with the first inlet and the second oil container is in fluid communication with the second inlet to recharge oil to the refrigeration equipment. The method for recharging oil recharges oil either from the first oil container or the second oil container in dependence of the type of fuel used in the vehicle.

An apparatus for transferring a fluid from and/or to a system, e.g., an air conditioning system, includes a main compartment having at least one pumping device for pumping the fluid from/to the system, an interface module having at least one gauge which is configured for displaying the pressure of the fluid, and a fluid connection fluidly connecting the gauge to the main compartment. The fluid connection is formed in a double conduit design in order to prevent any leakage of the fluid from the fluid connection.

A charging device includes: a first inlet configured to receive a first refrigerant in vapor form; a second inlet configured to receive the first refrigerant in liquid form; a third inlet configured to receive a second refrigerant in liquid form, where the second refrigerant is a different type of refrigerant than the first refrigerant; an outlet configured to output the first and second refrigerants to a refrigeration system; a first valve fluidly connected between the first inlet and the outlet; a second valve fluidly connected between the second inlet and the outlet; a third valve fluidly connected between the third inlet and the outlet; and a control module configured to selectively open the first, second, and third valves and charge the refrigeration system with target amounts of the first and second refrigerants, respectively.

A system and method for delivering a refrigerant to a refrigerant system. The system includes a distribution system comprising a distribution vessel, a transfer line, at least one pump, a distribution line and a distribution line branch arranged and disposed to transfer refrigerant from the distribution vessel to the refrigerant system. The system additionally includes a monitoring system comprising one or more sensors arranged and disposed to measure at least one distribution parameter within the distribution system and a recovery system arranged and disposed to selectively receive refrigerant based upon the refrigerant suitability for use in the refrigerant system.
