EXPANSION MODULE FOR A COOLANT

摘要

The invention relates to an expansion module (10) for a coolant, in particular an expansion module (10) for the controlled expansion of a coolant on the high pressure side of a refrigeration system or air conditioning system (12) to achieve a low pressure level, by means of at least one expansion valve (14). According to the invention, the expansion valve (14) of the expansion module (10) is configured as a type of sliding seat valve (16), the sliding seat (24) that acts as the valve plunger (22) being controlled by at least one pressure that prevails on the valve. The invention also relates to a coolant circuit, in particular a coolant circuit of an air conditioning system, comprising at least one expansion module of this type.
