  • Patent number: 9810438
    Abstract: A hydronic distribution system includes self-regulating valves networked together and operable to share valve temperature and valve position information with a microprocessor or other type of controller. The microprocessor runs one or more algorithms that process the temperatures and positions of the valves and then computes a desired speed for one or more variable speed pumps within the system. Controlling the pumps to operate at the desired speed and still maintain the correct amount of process fluid flow needed by the system reduces the overall energy use of the hydronic distribution system, saves on the operational lives of the pumps, and increases system efficiency.

  • Patent number: 9796242
    Abstract: In an air conditioner for a vehicle, a flow speed of air flowing through a first ventilation part of an evaporator is faster than a flow speed of air flowing through a second ventilation part of the evaporator when an intensive air-conditioning operation for a driver seat is operated, with respect to a case where a normal air-conditioning operation is performed. In this case, a correct target evaporator temperature is calculated to be higher by a predetermined temperature than a target evaporator temperature, and a detected temperature detected by an evaporator sensor is approached to the correct target evaporator temperature. Therefore, it can restrict the second ventilation part from being frosted.
