摘要： A method of sanitizing pipes, etc. In a hot water supply system includes the steps of normally heating water by driving water form a water storage tank, into a heat exchanger. Typically, a water pump is stopped once the water storage tank receives a particular percentage of hot water. However, when a sanitation mode is desired, the pump is not stopped, such that the water tank becomes all, or almost all, hot water. The hot water is then delivered to the pump, and from the pump to the heat exchanger, This hot water is thus operable to sanitize pipes and the pump.

摘要： A method of controlling a startup operation in a heat pump water heater system prevents inadvertent shutdowns and/or low operating efficiencies via closed loop control of the system. The method includes choosing an expansion valve opening at startup near an expected steady state value to ensure high system capacity as early as possible, setting a water pump signal to a high level to maximize cycle efficiency during warm-up, and applying closed loop control over the expansion valve and the water pump to increase the pressure in the system in a controlled manner until the system reaches a steady operating state. The method provides stable startup control even if a transcritical vapor compression system is used as the heat pump

摘要： An energy-efficient heat pump water heating system determines whether to energize a heat pump by interpreting readings from one or temperature sensors based on two thresholds. The heat pump is energized if the detected temperature falls below a first threshold and de-energized when the detected temperature rises above a second threshold. The thresholds may correspond to outputs of two or more sensors. Using multiple temperature thresholds improves the temperature sensing capabilities of the system, thereby improving energy efficiency by matching heat pump operation with hot water demand more closely than previously known systems.
摘要翻译：节能型热泵水加热系统通过基于两个阈值解读来自一个或温度传感器的读数来确定是否对热泵通电。如果检测到的温度低于第一阈值，则热泵被激活，并且当检测到的温度升高到高于第二阈值时，热泵被断电。阈值可以对应于两个或更多个传感器的输出。使用多个温度阈值提高了系统的温度感测能力，从而通过将热泵操作与热水需求相匹配来提高能源效率，比以前已知的系统更为紧密。

摘要： A control particularly useful for a hot water heating system, includes calculation of a desired leaving water temperature for water leaving a hot water heat exchanger, and a desired refrigerant condition for most efficiently achieving the desired leaving water temperature. A control looks at both desired variables and compares them to actual variables to determine an error for each. The control includes an error correction algorithm for each of the two variables that takes into account both of the errors, the integral of both of the errors, and the derivative of both of the errors. In this way, sensitivity in the error correction for one variable due to changes in the other variable is reduced, and the system functions more efficiently.

摘要： A PID control for a vapor compression system utilized to heat water identifies a particular range of error signals and derivative of the error signals that could be indicative of the cycle moving in an inefficient direction. If this determination is made, then a substitute for the error signal is utilized. In particular, the determination is made if both the error and the derivative of the error are negative. The substitute multiplies the error with its derivative to result in a positive product. This ensures the system will not move in the inefficient direction.
摘要翻译：用于加热水的蒸汽压缩系统的PID控制识别特定范围的误差信号和误差信号的导数，其可以指示周期在低效方向上移动。如果进行该确定，则使用错误信号的替换。特别地，如果误差和误差的导数均为负，则确定。替代品将误差与其导数相乘以产生积极的积分。这样可以确保系统不会以低效的方向移动。

摘要： A refrigerant cycle is provided with a control for an expansion device to achieve a desired compressor discharge pressure. The system operates transcritically, such that greater freedom over compressor discharge pressure is provided. The system's efficiency is optimized by selecting an optimum discharge pressure. The optimum discharge pressure is selected based upon sensed environmental conditions, and the expansion device is adjusted to achieve the desired compressor discharge pressure. A feedback loop may be provided to sense the actual compressor discharge pressure and adjust the actual compressor discharge pressure by further refining the expansion device. The system is disclosed providing heated water based upon a demand for a particular hot water temperature. Further, the optimum discharge pressures may be determined experimentally, with an offset added to the experimentally determined value to ensure that the actual pressure is higher than the desired, or optimum pressure for the particular refrigerant cycle. In one embodiment, a formula is utilized to determine the optimum discharge pressure.
