    摘要: A system and method for controlling a building system includes a supply temperature sensor upstream of a thermal load, a return temperature sensor downstream of the thermal load, and a controller. The controller is configured to calculate an actual thermal energy difference from the supply and return temperature sensors. The controller is configured to control a flow rate of a pump such that the measured thermal energy difference is equal to a desired thermal energy difference for the system, and the measured thermal energy difference is constant for a time interval. A system and method for controlling a building system includes determining a desired thermal energy difference for a load, measuring a supply and return temperature of the load, and reducing the system flow rate such that a valve controlling the load flow rate is at an at partially open condition when the return temperature of the load is the desired return temperature.

    摘要: A system and method are provided for activating and deactivating heating or cooling stages of a heating, ventilating, and air conditioning (HVAC) unit, which includes activating a heating or cooling stage of the HVAC unit based on a determined need for heating or cooling. A monitored temperature is compared with a first temperature setpoint and a monitored on-time of the heating or cooling stage is compared with a first time period setpoint. The heating or cooling stage is deactivated based on the comparison of the monitored temperature with the first temperature setpoint, when the monitored on-time is greater than the first time period setpoint. The monitored temperature is then compared with a second temperature setpoint. The heating or cooling stage is reactivated based on a comparison of the monitored temperature with the second temperature setpoint, when a monitored off-time is greater than the second time period setpoint.

    摘要: A heat exchange method which uses a heat exchange unit for exchanging heat between first and second media to adjust a temperature of the first medium. The method includes (a) a detection step of detecting temperatures of the first and second media to enter the heat exchange unit, and (b) an adjustment step of adjusting a flow rate of the second medium based on the temperatures of the first and second media detected in the detection step. The adjustment step includes (i) a target heat quantity calculation step of calculating a target heat quantity based on a target temperature of the first medium and the temperature of the first medium detected in the detection step, (ii) a first temperature difference calculation step of calculating a first temperature difference based on the target temperature and the temperature of the second medium detected in the detection step, (iii) a setting step of setting a provisional target flow rate of the second medium, (iv) a second temperature difference calculation step of calculating a second temperature difference based on the target heat quantity, the provisional target flow rate, and the temperatures of the first and second media detected in the detection step, (v) an average temperature difference calculation step of calculating one of a logarithmic average temperature difference and an average temperature difference at the heat exchange unit based on the first and second temperature differences, (vi) a heat exchange quantity calculation step of calculating a heat exchange quantity at the heat exchange unit based on one of the logarithmic average temperature difference and the average temperature difference and a heat exchange gain of the heat exchange unit, and (vii) a determination step of determining a target flow rate of the second medium based on a result of a comparison between the heat exchange quantity and the target heat quantity.
