摘要： A heating system is configured to optimize the speed and accuracy of the system in achieving various ambient air temperature setpoints, by modulating the heated water supply water setpoint to optimize the slope of the system's response curve. Optimized response curves are automatically determined by analyzing differences between ambient air temperatures over time in response to modulated supply water temperatures as they are reset upward or downward to achieve response times prioritized for improved occupant comfort. The controller of the heating system calculates a temperature slope, and adjusts the supply water setpoint to increase/decrease the speed of ambient temperature rise to achieve a desired slope.

摘要： Setting and maintaining proper pre-charge air pressure in a diaphragm or bladder-type expansion tank of any fluid system is essential for safe and efficient operation of that system. In usual practice, pre-charge air pressure checks are done by emptying the system of fluid and connecting an analog air gauge to the air input of the expansion tank. In this invention a pressure sensor that is permanently coupled to the fluid volume of the expansion tank is used to also evaluate the pre-charge air pressure in the tank. By employing a single sensor for both fluid and pre-charge air pressure evaluation, the problem of inconsistent calibration between fluid sensing and air pre-charge measuring devices is eliminated. Using the same permanently installed sensor for every test or adjustment in a given system eliminates the problem of variations in calibration between different sensors or gauges used at different testing times.

摘要： The present invention relates to HVAC-systems operating under new ZERO-MIXING (ZM) water flow condition as innovative way to promote consistent highly energy efficient performance on SOURCE-heating/cooling thermal production and BUILDING's system distribution (FIG. 1). ZM technology is applicable; but not limited, to large-residential, commercial, institutional, and industrial facilities. Current state on HVAC technology, for system hydronics loop-flow, do not provide flows temperature segregation mechanisms between heating/chiller-plants hot/cold water supply and warmer water system returns. The result, a system that continuously operates at WATER MIXING conditions that impair equipment efficiency and output, and therefore, overall system energy performance.
