Latest Patents

One of Kraning's latest patents is an agricultural vehicle cab automatic temperature control system. This invention features an improved HVAC control system designed for combines. The frame of the combine supports an operator cab, a harvesting head, and other operational systems. The control system includes an operator control and a heat exchanger located in the cab. It also incorporates at least one sensor to monitor ambient air temperature, cab air temperature, and solar loading. The operator control generates a set-point signal for the desired cab air temperature. An interface circuit is electromagnetically coupled to the valve assembly, operator control, and sensors. This system produces a temperature differential based on the comparison of the set-point signal to the sensed signals, applying electrical control signals to the valve, compressor, and blower to achieve the desired cab air temperature.

Another patent by Kraning is the agricultural vehicle cab temperature control system, which also features an improved HVAC control system. This design includes an operator control located at the roof of the cab and a heat exchanger at the floor. The interface circuit is electrically coupled to the control circuit and heat exchanger valve, regulating the heat output. A cooling coil may also be present at the floor of the cab, with the control and interface circuit working together to manage the associated coolant compressor.
