1 TARIFF A dishwasher containing a heat pump. This invention relates to a dishwasher that incorporates a heat pump. To reduce energy consumption and improve drying performance in dishwashers. Heat pumps are used. In dishwashers with heat pumps, the compressor is 5 A heat pump is formed by condenser, throttling valve, and evaporator elements. The pump components are connected by a pipeline, and the loop is located within the pipeline. The heat pump operates thanks to the fluid. The condenser is a PBR tube with a hot surface. Demet Dr. and the dishwasher water are heated by being placed inside the water. This is provided. The evaporator is a cold surface and is positioned in such a way that it will be in contact with the ambient air. The evaporator extracts heat from the environment, and this heat is transferred to the compressor and condenser. This type of heat pump system uses a compressor for water heating. The system is operated by heating the water in the condenser and heating the water by absorbing heat from the evaporator. Condenser support is provided. The compressor pressurizes the circulating fluid. It sends the circulating fluid to the condenser. The circulating fluid passes through the condenser and goes to the evaporator. 15 The circulating fluid returns to the compressor after the evaporator. The fluid that enters the compressor is sent back to the condenser, completing the cycle. This Thanks to this, heating the washing water is much better than conventional dishwashers with heaters. It occurs in a more efficient manner. However, heat pump dishwasher systems involve many dynamics during the water heating process. It depends on the situation. If these situations are not brought under control, there will be inefficiencies in the system. This can occur. For example, in the chassis volume of a dishwasher with a heat pump system. Because of its location, the air is drawn from the lower chassis volume by fans and blown onto the evaporator. air temperature depends on the increasing temperatures of the components during the cycle. is increasing and thus the evaporation temperature increases by g. Y on the condenser side is 25 Since the same water is constantly being heated, the temperature of the heated water changes the condenser capacity. Since there is no dynamic control system on the system to respond to this situation, water As the system heats up, its efficiency decreases and the compressor's operating conditions become strained. 2 In the European patent document numbered EP3148392B1, which is included in the technical status...
