Abstract: An air-conditioning system for a motor vehicle has a coolant circuit which comprises an electrically driven compressor, a condenser, an expansion valve and a latent cold holdover. Heat extracted from the latent cold holdover by the coolant circuit. This is referred to as charging the latent cold holdover. In addition, an air cooling mechanism is provided that extracts heat from the air and is fed to the latent cold holdover. The air-conditioning system can thus be particularly compact and effective as an air-conditioning system for operation in a stationary vehicle.

Abstract: The invention relates to a multi-chamber tube, produced from a flat sheet (2), welded along the longitudinal surfaces with two planar face surfaces (5, 6), two curved narrow sides (3, 7) and webs (8), folded from the flat strip (2) which divide adjacent (chambers (9, 10) and which are soldered to the opposing tube inner wall (6) and a method for production thereof. According to the invention, the flat strip (2) comprises inward projections (15) in the region of the soldering of the webs (8).

Abstract: A system for heating and cooling the interior of a motor vehicle, having a refrigerating circuit with a first climate control device (10) which is designed to heat or cool the front area of the interior, and with a second climate control device (12) which is designed to heat or cool the rear area of the interior. The first climate control device (10) has a first evaporator (14) and the second climate control device (12) has a second evaporator (16). The second climate control device (12) also has a first heat exchanger (18) which is connected via a heat transfer medium circuit (30) to a latent cold storage device (20) which can be charged with cold by a third evaporator (22) which can be connected to the refrigerating circuit.

Abstract: Procedure for equilibration of the delivery volumes of a multi-channel metering apparatus with an arrangement of independently controlled dispensing channels 1.1-1.n, delivering individual volumes of dispensing fluid to cavities 3.1.1-3.n.n, where measured values relevant to the individual delivery volumes are measured for the same control value and from which an adjustment value is specified with a tolerance band and the control value is adjusted for dispensing channels 1.1-1.n, the measured values of which lie outside the tolerance band. The invention also applies to an apparatus for implementing the procedure.
