Heat pumps are used for this purpose. In heat pump dishwashers, the compressor is 5 A heat pump is formed using 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 tube with a hot surface. It is a bundle and is placed in the dishwasher washing water to heat the water. This is provided. The evaporator is a cold surface and is placed in contact with the ambient air. 10 The evaporator extracts heat from the environment, and this heat is transferred to the compressor and condenser. It enables the transmission of heat. In such heat pump systems, water heating is performed. The compressor is started, heating the water in the condenser, and the evaporator extracts heat from the environment. The compressor is designed to support the condenser that heats the water. It heats the circulating fluid. It sends the fluid to the condenser by pressurizing it. The circulating fluid passes through the condenser and 15 The fluid flows to the evaporator. After the evaporator, the refrigerant goes to the compressor. The fluid coming to the compressor is sent back to the condenser, thus recirculating the cycle. This completes the process of heating the washing water, unlike conventional heated dishwashers. It is carried out much more efficiently than other machines. However, the evaporator is in the environment. Because it involves direct heat exchange, heat pump systems can handle varying ambient temperatures. by changing working conditions, the energy and time spent on heating the water This has an effect.
