Conditioning system for a vehicle and method of drying an evaporator of an air conditioning unit provided in such a conditioning system
A conditioning system for a vehicle comprises an evaporator, positioned in an air conducting channel means, of an air conditioning unit, by means of which evaporator heat and/or moisture can be removed from the air to be introduced into a vehicle interior, a heating means being provided at the evaporator for at least local heating of the same.
1. A conditioning system for a vehicle, comprising an evaporator ( 16 a ), positioned in an air conducting channel means ( 12 a ), of an air conditioning unit, by which evaporator ( 16 a ) heat or moisture is to be removed from the air to be introduced into a vehicle interior, a heat exchanger ( 24 a ) being provided in the air conducting channel ( 12 a ), by which heat is supplied to this circulating air, and wherein the air conducting channel ( 12 a ) is settable in a first air conducting state in which air flows first around the heat exchanger ( 24 a ) and thereafter the evaporator ( 16 a ) such that the heat exchanger ( 24 a ) is upstream of the evaporator ( 16 a ) in an air flow direction in an evaporator drying operation phase, and wherein the air conducting channel ( 12 a ) is settable in a second air conducting state, in which air first flows around the evaporator ( 16 a ) and then around the heat exchanger ( 24 a ), wherein an air forwarding fan ( 14 a ) is arranged in the air conducting channel means ( 12 a ) upstream of the evaporator ( 16 a ) and the heat exchanger ( 24 a ) in the first air conditioning state and the second air conditioning state.
2. The conditioning system according to claim 1 , wherein with the air conducting channel ( 12 a ) set in the first air conducting state, the air conducting channel means ( 12 a ) does not introduce air flowing around the evaporator ( 16 a ) into the vehicle interior.
3. The conditioning system according to claim 1 , wherein with the air conducting channel ( 12 a ) set in the first air conducting state, the air conducting channel means ( 12 a ) introduces the air flowing around the evaporator ( 16 a ) substantially into a region near a floor of a vehicle interior.
4. The conditioning system according to claim 1 , wherein the air conducting channel is settable in a third air conducting state, in which air flows around the evaporator without flowing around the heat exchanger.
5. The conditioning system according to claim 1 , wherein the air conducting channel is settable in a fourth air conducting state, in which the air flows neither around the heat exchanger nor the evaporator.
