Abstract: A refrigeration system (10) for a motor vehicle with a mid or rear engine has an air-conditioning compressor (12) can be driven by the mid or rear engine for delivering a coolant. At least one evaporator (16) is provided for cooling a frontal part of the passenger compartment by evaporating the coolant. At least one condenser (22) condenses the coolant and a heat exchanger (20) cools the coolant flowing to the evaporator (16) with cold from the coolant coming from the evaporator (16). A control unit (26) limits a temperature of the coolant entering the air-conditioning compressor (12) to avoid a temperature that is damaging for the air-conditioning compressor (12), while also taking account of heating of the coolant along a particularly long flow path from the rear area (18) of the motor vehicle to the air-conditioning compressor (12) arranged at the mid or rear engine.

Abstract: The present invention is directed to a method for the determination of at least 3 analytes using specific binding partners. Combinations of detectable labels are coupled to the binding partners assuring that each binding partner molecule is coupled with only one detectable label. This allows the determination of more different analytes than different labels used by not limiting the range of useable labels. The present invention is also related to kits, composition of matters and their use.
