Definitions

the invention relates to a method for controlling or controlling linear or non-linear dynamic systems of a heat pump system, in which the outputs of the system are estimated in advance and included in the scheme.
Heat pumps have long been state of the art.
a heat pump consists of a refrigerant circuit with an evaporator, a compressor, a heat sink, a condenser and a heat source.
a refrigerant having a low boiling point at a low temperature is vaporized with heat absorption and then compressed while remaining heated but gaseous.
the heated gas is then fed to a heater in which it gives off heat to the environment, usually the interior of a residential building, and condenses. Then it is relaxed, usually in an isenthalp throttle valve, cools down and is then returned to the heat source, this is usually soil or ambient air.
a maximum utilization of the heat pump can only be achieved by a meaningful integration of restriction sizes. For most concepts, these are not calculated accurately enough or integrated into the concept, which can lead to low or high pressure shutdowns of the heat pump. Furthermore, the heat exchanger often freezes, even in situations where freezing can be avoided using a model-based design.
Model-based predictive control concepts are ideally suited for regulating coupled multivariable systems. Due to the fact that the controller is based essentially on the essential dynamic properties of the input and output variables in the form of a model, a high degree of control quality can be achieved. This model is purely mathematical, it does not need to include ambient temperatures, weather forecasts and typical user behavior in the control concept, nor to implement a physical model.
the outputs y of the system can be predicted and included in the control for a certain prediction horizon.
the controller responds early to a changing reference variable and can ideally follow this, taking into account restrictions.
this rule has two objectives. On the one hand, you want to cover the heating demand via the temperature and the volumetric flow of the useful heat flow. On the other hand, the "coefficient of performance COP", which is a guiding principle for the efficiency of the heat pump, should be as high as possible, preferably between 3.1 and 5.1. In this case, the heat obtained is related to the electrical power consumption. In this COP, not only the temperatures and heat flows, but also the electrical power consumption of the heat pump, which thus also has an influence on the regulation of the electrical consumers. If you want to optimize this COP, the control of these coupled systems is complex, because the sum of the drive power of the machines must be minimized.
the US 2008/0000241 A1 describes a refrigeration system with a compressor and associated control. For this purpose, the future cooling demand is compared with the capacity of the compressor and weighted as a reference variable higher than the current refrigeration demand. A cost model will further optimize refrigeration.
the compressor is not operated as an inverter, but has only a start-stop control. And the estimate of the upcoming refrigeration needs is based on the environment of the operator, such as the opening hours of a supermarket. So the machine can not do it autonomously.
the US 2015/0253051 A1 describes pre-estimation methods that estimate the heat transfer of fluids under different environmental conditions. These fluids are the working fluid, the heat sink and the heat source. For this purpose, a function of the setpoint of a heating element is determined by changing the setpoint and correspondingly solving the function for intermediate values. Through a variety of such operations, the objective function for the setpoint is optimized. In this way, historical operating data for temperature control can be used.
the object of the invention is therefore to provide a suitable control method for the operation of a left-handed thermodynamic Clausius-Rankine cycle in a closed, hermetically sealed working fluid circulation by means of a working fluid.
a prediction horizon is formed for each variation of manipulated variables with influence on the electrical consumption variables caused by machines, the total minimum of the electrical energy consumption is subsequently determined for each of the control actions possible on account of the prediction horizons, and these settings for the Control intervention to be selected.
the desired value of the second reference variable COP value is set to the possible maximum value. In this way it is achieved that always the best COP value is sought, which is achievable at all.
soft limits are used to limit the reference variables. In practice, this is done in such a way that cost functions are designed in such a way that, whenever a reference variable comes close to a boundary, it calculates higher virtual costs, which means virtual costs in a regulatory sense.
the control system also has the advantage of being fast and stable.
Fig. 1 shows a simple air / water heat pump system, which from a control point of view is a MIMO (multi-input multi-output) system.
the heat pump system comprises in this example a refrigeration circuit 1 with a refrigeration compressor 2, a condenser 3, an expansion valve 4 and an evaporator 5.
compressed refrigerant 6 flows to the condenser 3, where it gives off its heat to the heat carrier flow 7, which is supplied by the circulation pump 8 is promoted as heat flow 9 to the consumer.
the thereby cooled and condensed refrigerant 10 reaches the expansion control valve 4, wherein it continues to cool and is passed as a cooling flow 11 in the evaporator 5.
the heated refrigerant 15 is again compressed by the refrigerant compressor 2, whereby the refrigeration cycle 1 is closed.
the refrigeration circuit shown here in simplified form may also include a plurality of heat exchangers at different temperature levels, a stepped pressure reduction, switching devices for heating operation in winter and cooling in summer, and a variety of sensors, the control principle is the same.
evaporator 5 and capacitor 3 are interchangeable in their operation or not shown switching devices in the refrigerant circuit can produce this functionality in the prior art, so that the heating circuit to the refrigeration cycle of an air conditioner and the heat source of the heating operation Heat sink in the air conditioning.
the refrigerant circuit 1 is thermodynamically on the sizes pressure, temperature and flow for the four streams compressed refrigerant 6, condensed refrigerant 10, refrigerant flow 11 and heated refrigerant 15, as well as the sizes volume flow and temperature of the four streams heat transfer stream 7, heat flow 9, ambient air 12 and cold air 14 certainly. It is possible to regulate the power consumption or rotational speeds of the circulation pump 8, that of the refrigeration compressor 2 and that of the fan 13, and also the position of the expansion valve 4.
Fig. 2 shows a basic course of a prediction system.
the output quantities y, 16 are predicted via a prediction horizon 17 and included in the regulation.
the controller responds early to a changing reference variable, the setpoint curve w, 18, and can follow this, taking into account restrictions, ideally by the manipulated variable u, 19.
the reference trajectories r, 20 and the setting horizon 21 are also shown.
the values y, w and u are to be understood as vectorial values.
the flow temperature in the heating circuit is adjusted by controlling the four essential input variables of the compressor, the expansion valve, the fan and the circulating pump in parallel, while maintaining the operating limits for high pressure and evaporating temperature.
Fig. 3 shows in seven measurement diagrams the operation of this regulatory procedure. In all diagrams, the time axis is identical, it is the same control process. In the uppermost diagram, the measured flow temperature 22 of the heat flow 9 and the target temperature 23 is shown.
the target temperature 22 was raised as a model, the heat pump was led to its load limit. Subsequently, the setpoint temperature was lowered sharply and slowly increased to an intermediate level.
the diagram below shows the pressure 24 in the high-pressure section 6 or 10 of the refrigeration circuit 1. This pressure curve results in response to the flow temperature 22 in the condenser 3 from the temperature to which the refrigerant cools when condensing, ie to the equilibrium temperature. He may not exceed a maximum pressure 25.
a control intervention in the compressor and in the expansion valve has been required.
the evaporator temperature 26 is shown, which is proportional to the low-pressure section 11 and 15, respectively.
the temperature in the evaporator was lowered accordingly, so that the temperature difference to the air of the environment is greater and a higher heat flux of the ambient air can be withdrawn.
this lower limit is shown by minimum evaporator temperature 27.
the input of the speed 28 of the refrigerant compressor 2 is shown. This speed must be between the limits of the minimum speed 29 and the maximum speed 30. It can be seen that the regulation initially wants to satisfy the increased heat requirement by means of a higher rotational speed, which causes a higher compression of the refrigerant, but at the same time reaches its upper limit.
This expansion valve 4 opens when the heat demand can not be achieved by a further increase in the speed of the refrigerant compressor 2. Through this opening, the mass flow through this valve increases, in parallel to the compressed by the refrigerant compressor mass flow, which leads due to the compressor line to a corresponding pressure drop in the high pressure section. Also with respect to the opening of the expansion valve 4, a maximum opening 32 and a minimum opening 33 is predetermined as a limit.
the diagram below shows the input variable of the fan speed 34.
the fan speed increases to promote more ambient air to the evaporator surface to remove this heat.
a maximum speed 35 and a minimum speed 36 is set. In the present case, reaching the maximum speed 36 is not sufficient to bring the flow temperature closer to the setpoint.
the diagram below shows the input quantity of the rotational speed 37 of the circulating pump 8.
the circulation pump reduces its speed, but only up to the minimum speed 38, which is not achieved in the present example, since the target value of the flow temperature 23 has previously been lowered.
the circulation pump is limited by a maximum speed 39.
Fig. 4 shows a control method, which builds on the example shown above.
the measurement diagram shows one tenth of the time course compared to Fig. 3 .
the COP should be used as a further output variable.
the flow temperature 22 is replaced by a setpoint temperature 23, but also an upper flow temperature limit 40 and a lower flow temperature limit 41.
the COP is from the heat flow, which is the difference between the flow temperature and the return temperature of the heating circuit, multiplied by the mass flow, funded by the circulation pump 8 is compared with the sum of all electrical consumers of the heat pump.
the target COP 42 is set as high as possible, while the actual COP 43 the target COP is approximated by the regulation of refrigerant compressor, fan and circulation pump takes place so that the total electrical energy consumption decreases, while the flow temperature is kept within narrow limits.
This COP which is as high as possible within the specified conditions, ideally achieves constant maximization of the COP.
the set target temperature 23 is at the beginning of the observation interval 24.5 degrees Celsius, this also corresponds to the starting temperature of the flow temperature 22.
the COP increases from 3.57 to 3.62, while the flow temperature remains the same.
the setpoint temperature 23 is lowered to the value of 24.1 degrees Celsius. This initially causes a short increase in the COP due to the heat storage capacity of the system. As the flow temperature approaches the new setpoint temperature, the COP remains at approximately the level that it had reached before the setpoint temperature change, namely approximately 3.62.
the transient temperature of the flow temperature is over after about 2100 seconds, the COP from then 3.62 further upwards, at the end of the observation interval it is 3.63. In this way, a continuous optimization process is carried out.
