Abstract

A system for heating and cooling the interior of a motor vehicle includes a first climate control device designed to heat or cool the front area of the interior, and a second climate control device designed to heat or cool the rear area of the interior. A first evaporator is connectable to a cooling circuit assigned to the first climate control device and a second evaporator is connectable to a second cooling circuit assigned to the second climate control device. The second evaporator is located in a latent storage in order to charge the latent storage with cold and the second climate control device contains a first heat exchanger designed to transfer the cold removed via the heat transfer medium circuit or the second cooling agent circuit from the latent storage for cooling of the rear area of the interior by an air flow.

Dependent claims

A system for heating and cooling the interior of a motor vehicle, comprising:

a first climate control device adapted to heat or cool a front area of the interior;
a first cooling agent circuit connected to said first climate control device;
a first evaporator connected to said first cooling agent circuit;
a second climate control device adapted to heat or cool a rear area of the interior and including a first heat exchanger;
a second cooling agent circuit connected to said second climate control device;
a heat transfer medium circuit connected to the first and second climate control devices;
and
a latent storage connected to said second cooling agent circuit and including a second evaporator adapted to charge said latent storage with cold;
wherein said first heat exchanger transfers cold from said latent storage, via said second cooling agent circuit to said second climate control device for cooling of said rear area of the interior.
