Abstract

The invention provides an apparatus and a method for recovering fluid refrigerant. An apparatus (2) for transferring a fluid from and / or to a system, in particular an air conditioning system, includes a main compartment (9) comprising at least one pumping device for pumping the fluid from / to the system, an interface module comprising at least one gauge (4a, 4b), which is configured for displaying the pressure of the fluid, and a fluid connection (13) fluidly connecting the gauge (4a, 4b) to the main compartment (9). The fluid connection (13) is formed in a double conduit design in order to prevent any leakage of the fluid from the fluid connection (13).

Description

technical field [0001] The present invention relates to apparatus and methods for safely transferring (eg, recovering, evacuating and / or filling) fluid refrigerant from / to a refrigeration system. Background technique [0002] From time to time, the refrigerant circulating in a refrigeration cycle, such as that of an air conditioning system, needs to be replaced and / or topped up in order to ensure proper operation of the refrigeration cycle. [0003] A device is known from US 2008 / 0276634 A1 for transferring (in particular recovering, emptying and / or filling) fluid from / to a system, in particular refrigerant from / to a refrigeration cycle. [0004] However, since the fluid may contain flammable substances, it needs to be ensured that the fluid does not escape into the environment, and in particular that it does not come into contact with the electrical equipment of the recovery device, which could ignite the flammable substances contained in the fluid.
