| 20080229721 | AIR FILTER AND FAN DEVICE FOR VEHICLE VENTILATION SYSTEMS - An air filter and fan device for a vehicle ventilation system is disclosed that, in direction of air flow, includes an air filter, an impeller, and a flow-off channel. A casing is provided that accommodates the impeller and the flow-off channel in an enclosing manner such that the impeller is established with double-suction, receiving air from the air filter from both a first side and a second side or the impeller. | 09-25-2008 |
| 20080230204 | AIR CONDITIONING UNIT FOR VEHICLES - The invention relates to an air conditioning unit provided with means for cooling and heating air, including a casing with a plurality of air outlets. At least one heating heat exchanger is provided that in its vertical extension has at least one cold air passage whereby, the one cold air passage is disposed between two heating paths. An evaporator is provided, downstream of which in direction of the air flow the heating heat exchanger is disposed, such that after the heating heat exchanger there is a temperature-layered air flow, the layers of which are wholly or partly assigned directly to the air outlets. | 09-25-2008 |
| 20100006258 | VEHICLE AIR CONDITIONER - A vehicle air conditioner is disclosed having means to cool and heat air with three air paths, of which, two outer air paths have a common first temperature and an inner air path has a second temperature, wherein a means for controlling the air volume flow through the outer air paths and the inner air path is provided by two control elements which are configured jointly to be able to move in opposing directions. | 01-14-2010 |
| 20110174000 | METHOD FOR OPERATION OF AN HVAC SYSTEM - A method for operating an HVAC system includes the steps of adjusting a heating temperature of a heat exchanger disposed in a first flow passage, directing a first partial air mass flow through the first flow passage, directing a second partial air mass flow through a second flow passage, and directing the first partial air mass flow and the second partial air mass flow downstream of the first flow passage and the second flow passage, wherein the heating temperature of the heat exchanger required to at least one of achieve and maintain a desired climate in the passenger compartment of the vehicle is set as a maximum heating temperature for the heat exchanger, and wherein only an amount of energy required to at least one of achieve and maintain a desired climate in the passenger compartment of the vehicle is added to the HVAC system. | 07-21-2011 |
| 20120003910 | HVAC SYSTEM FOR VEHICLES WITH BATTERY COOLING - An HVAC system for a vehicle including a battery casing having a battery disposed therein, an air conditioning device in fluid communication with a passenger compartment of the vehicle, and an air distribution system including an outflow channel and a return channel. The outflow channel fluidly connects the battery casing with an ambience of the vehicle and the return channel fluidly connects the battery casing with the passenger compartment. The air conditioning device includes an ambient air channel for receiving an air mass flow from the vehicle ambience, a recirculating air channel for receiving an air mass flow from the passenger compartment, and a battery cooling channel to fluidly connect the air conditioning device and the battery casing. The conditioned air mass flow from the air conditioning device is directed into the passenger compartment and/or the battery casing to maintain a desired temperature of the passenger compartment and/or the battery. | 01-05-2012 |
