Abstract:
In a switch cabinet or enclosure with an air-conditioning unit that contains a cooling circuit system with an evaporator and a condenser, wherein the evaporator has an integral air circuit spatially connected to an interior of the switch cabinet and through which air of the switch cabinet interior is conveyed by a blower, and wherein the evaporator is connected to remaining components of the cooling circuit by refrigerant lines, the improvement comprising: the evaporator (13) and a dedicated blower (14) integrated into an evaporator unit (11) arranged on the switch cabinet (10), the condenser (33) and a dedicated blower (36) integrated into a condenser unit (30), the condenser unit (30) arranged spatially separate from the evaporator unit (11) and spatially separate from the switch cabinet (10), the evaporator unit (11) connected to the condenser unit (30) by an incoming refrigerant line (21) and an outgoing refrigerant line (22) that bridge a free space between the evaporator unit (11) and the condenser unit (30), couplings (23) having two coupling elements installed into the incoming and the outgoing refrigerant lines (21, 22), each said coupling element connected to an end of one of the incoming and the outgoing refrigerant lines (21, 22) in a pressure-tight manner, and the two coupling elements of one of the couplings (23) one of connected and separated by a rapid-action closure;wherein the evaporator unit (11) has a housing that accommodates the evaporator (13) and is one of attached to the switch cabinet (10) and positioned in the switch cabinet, the housing has a central air inlet opening (19) through which the air of the switch cabinet interior is conveyed into the housing, air outlet openings (18) through which the cooled air is conveyed from the housing into the switch cabinet interior are arranged laterally of the air inlet opening (19), and the air outlet openings (18) have an adjustable air flow control that varies at least one of an air flow direction and a quantity of air conveyed.
