Heating and air-conditioning system for a motor vehicle

Abstract

A heating and air-conditioning system for a motor vehicle, having at least one running-state system having a heat exchanger and a blower to supply an air flow across the heat exchanger; and a stop-state system having a heat carrier loop connected to the running-state heat exchanger, wherein coolant within the heat carrier loop can stream through the running-state heating heat exchanger. The system can include a housing having a stop-state coolant heater or cooler, a pump to move a coolant through the heat carrier loop, a controller to control the pump and the running-state blower (including the use of a temperature sensor), a power supply, which is available in a stopped state, and a blower to supply an air flow across the running-state heat exchanger. The housing can have a connection interface corresponding to running-state air ducts, whereby retroactive installation of the system is facilitated.

1 . A heating and air-conditioning system for a motor vehicle, comprising:
 at least one running-state system having a heat exchanger and a blower to supply an air flow across the heat exchanger; and   a stop-state system having a heat carrier loop connected to the running-state heat exchanger, wherein coolant within the heat carrier loop can stream through the running-state heating heat exchanger.   
   
   
       2 . The system of  claim 1 , wherein the running-state system has a heat carrier loop connected to the heat exchanger. 
   
   
       3 . The system of  claim 1 , wherein the stop-state system heat carrier loop has a coolant heater, a pump to move a coolant through the heat carrier loop, a controller to control the pump and the running-state blower, and a power supply, which is available in a stopped state. 
   
   
       4 . The system of  claim 1 , wherein the stop-state system heat carrier loop has a coolant heater and a coolant cooler, a pump to move a coolant through the heat carrier loop, a controller to control the pump and the running-state blower, and a power supply, which is available in a stopped state. 
   
   
       5 . The system of  claim 3 , wherein the stop-state coolant heater and pump are contained within a housing located in a rear region of the vehicle cabin interior. 
   
   
       6 . The system of  claim 3 , wherein the stop-state coolant heater and pump and a stop-state blower to supply an air flow across the running-state heat exchanger are contained within a housing located in a rear region of the vehicle cabin interior. 
   
   
       7 . The system of  claim 3 , further comprising a temperature sensor connected to the controller. 
   
   
       8 . The system of  claim 6 , wherein the running-state system further comprises ducts to direct the flow of air across a running-state heat exchanger and into a vehicle cabin interior. 
   
   
       9 . The system of  claim 8 , further comprising an air vent at the distal end of the ducts. 
   
   
       10 . The system of  claim 8 , wherein the housing has a connection interface corresponding to the configuration of running-state ducts, whereby retroactive installation of the system is facilitated. 
   
   
       11 . A heating and air-conditioning system for a motor vehicle, comprising:
 at least one running-state system having a blower to supply an air flow across at least the running-state heat exchanger and through at least one air duct terminating in a vehicle cabin;   a stop-state system having a heating loop with water heater to provide heat to heat cooling water streaming into a second heating heat exchanger; and   the running-state blower further supplying a flow of air across the second heat exchanger.   
   
   
       12 . The system of  claim 11 , wherein the stop state system can further comprise a module to house the heating loop. 
   
   
       13 . The system of  claim 12 , wherein the module is suitable for mounting inside the rear of a vehicle cabin. 
   
   
       14 . The system of  claim 11 , further comprising a running-state blower to supply a flow of air across the second heat exchanger and through at least one air duct terminating in a vehicle cabin.
