  • System and method for HVAC interlocks
    Patent number: 9921591
    Abstract: An interlock function block system, method, and apparatus that reduces the necessity for a building automation programmer to program low-level instructions using a complex series of ANDs, ORs, and arithmetic functions to protect such devices is provided.
    Type: Grant
    Filed: March 14, 2013
    Date of Patent: March 20, 2018
    Assignee: Siemens Schweiz AG
    Inventors: Franz Renggli, Marcel Walti, William Thomas Pienta, Virgil Seribo, James J. Coogan
  • Method for regulating room comfort variables
    Patent number: 9285135
    Abstract: An appropriately treated flow of air is supplied to a room in an automatically executed pulsed operation, in which the air flow is alternately switched on and switched off. The air flow is switched off independently of the room usage state if the regulated room comfort variables lie within a respectively assigned comfort band. If at least one of the regulated room comfort variables lies outside the comfort band assigned to it, the flow of air minimized in respect of its volume is supplied to the room. This means that ventilators used for the exchange of air will be operated at the lowest possible speed, optimized in respect of time and thereby with high energy efficiency.
