Definitions

• the invention relates to a method for controlling a heating, cooling and / or air conditioning system according to the preamble of claim 1.
• Generic systems consist of at least one heat and / or cooling device and at least one heating and / or cooling circuit with a flow line and a return line to a heat and / or refrigeration consumers.
• Heat pumps take over the function of heating and cooling in practice, since this is relatively easy to implement with cycle reversal. This makes it possible to use connected heating circuits also for cooling rooms or buildings.
• the design of the heating and / or cooling circuits takes place in these cases also after the existing heat transfer surfaces of the heat and / or cold consumers, such as underfloor heating and radiators. It is essential to avoid condensing in the working space. Just as with all pipes of heating and / or cooling circuits installed in a building.
• a control device which regulates a flow temperature setpoint in the cooling circuit is therefore connected in known systems with a humidity monitor in the cooling circuit and switches off the refrigeration device as soon as a condensation on the flow line of the cooling circuit is detected.
• These humidity monitors have a fixed cut-off value, which is usually set by a plumber when commissioning the system.
• Such a moisture monitor is as a standard component of the EP 0 676 375 A2 known. It serves to shut down an ozone generator, which should not be exposed to moist air.
• the invention is therefore based on the object to optimize the control of a heating, cooling and / or air conditioning system with at least one heat and / or cooling device mainly in cooling mode.
• the method for controlling a heating, cooling and / or air conditioning system is characterized in that the flow temperature setpoint in the cooling circuit is raised by a predeterminable amount each time the humidity switch is triggered.
• the increase of the flow temperature setpoint in the cooling circuit is in each case in steps of about two Kelvin, wherein this value is variably adjustable.
• the increase in the flow temperature setpoint in the cooling circuit is gradually and gradually lowered again in a predeterminable cycle. This takes place until the increase is canceled again and the flow temperature determined by the control device as a function of the operating state applies. It is preferably lowered in a cycle of about one Kelvin per hour, wherein the cycle starts with the first lowering step about one hour after the last increase of the flow temperature setpoint.
• the cooling circuit is temporarily switched off as soon as the desired flow temperature in the cooling circuit has reached a level by repeated lifting, in each case due to the triggering of the moisture guard, at which a cooling operation is no longer possible.
• This threshold is variable and is determined by the control device in a known manner, inter alia, from the desired room temperature and the current outside temperature.
• the invention is a simple method for controlling a heating, cooling and / or air conditioning system with at least one heat and / or cooling device, which mainly optimizes the cooling operation, in particular the operation of the refrigeration device. According to the invention thus caused by the triggering of the moisture monitor on the flow line of the cooling circuit switching cycles of the cooling circuit and the refrigeration device are reduced. This brings special For heat pumps very positive effects in terms of energy efficiency, because the required in such refrigeration units minimum running times are met.
• the heating, cooling and / or air conditioning system automatically and flexibly levels off to a current system operating state in cooling mode best suited flow temperature in the cooling circuit.
