Abstract: The invention relates to a compressor unit (200) for a refrigeration system using a refrigerant. The compressor (200) unit comprises a centrifugal compressor (201) for compressing the refrigerant, wherein the compressor (201) has a discharge outlet (204) for discharging the compressed refrigerant,anda check valve (1; 100; 301a). An inlet (83) of the check valve (1; 100; 301a) is in fluid connection with the discharge outlet (204) of the compressor (201). In order to provide a more reliable and more quite compressor unit (200), the check valve(1; 100; 301a) is a nozzle check valve including a damping mechanism (41, 50; 50, 141), wherein a closing parameter of the check valve (1; 100; 301a) is between 50 s/m² and 2000 s/m², wherein the closing parameter is a closing time of the check valve (1; 100; 301a) divided by a port area of the check valve (1; 100; 301a).

Abstract: A common unit (10) for a refrigerant gas handling system (1) is described, the common unit (10) comprising an accumulator (4), a check valve (11), and a reversing valve (3). The accumulator (4), the check valve (11), and the reversing valve (3) are integrated in the common unit (10). Such a system should facilitate mounting of a VRF or VRV system and should be easy to produce. To this end, the common unit (10) is accommodated in a shell, wherein the shell can withstand at least twice atmospheric pressure, wherein the shell comprises a housing (14) that houses the check valve (11) and the reversing valve (3), an accumulator shell, and a tube (13) connecting the housing (14) and the accumulator shell.

Abstract: The present invention relates to a valve arrangement (2) for an operation mode selector of an air conditioning system, the valve arrangement (2) comprising a tube element (3) which comprises a discharge port (4), a suction port (5) and an evaporator port (6), the valve arrangement (2) furthermore comprising two or more mode selecting valves (9, 10) being arranged for selectively establishing a fluid connection through either the discharge port (4) or the suction port (5). It is the object of the invention to provide a compact design while still allowing silent switching between operation modes. The object is solved by one or more of the mode selecting valves being two-step opening valves. The invention furthermore relates to a pipe arrangement (1) comprising one or more of those valve arrangements (2) and an air conditioning system comprising such a valve arrangement (2) or such a pipe arrangement (1).
