The temperature is measured and the temperature of the heat exchanger is set by the manufacturer at 5 When the value drops below this level, the condensate water in the tank flows onto the heat exchanger. This is directed towards the latent heat while the air conditioner is operating in cooling mode. The condensate water that is produced is used, and with less energy consumption. A frozen boundary layer is formed on the surface of the heat exchanger. Additionally, ice... the boundary layer forms faster and with less energy consumption 10 is provided. The invention's application involves the icing process on the surface of a heat exchanger. After completion, the air conditioner is operated in cooling mode to allow the heat exchanger to cool down. The ice that accumulates on its surface as it heats up, along with dust and dirt trapped in the boundary layer, forms a 15 They are dissolved together and discharged from the surface of the heat exchanger. Thus, dust and dirt are trapped in the ice boundary layer on the heat exchanger surface. The dissolved water is discharged from the heat exchanger surface. In this way... faster and with less energy consumption, the heat exchanger cleaning function It is being completed. 20 A cooling device, implemented to achieve the purpose of this invention, is shown in the attached figures. as shown, from these figures; Figure 1 – Flowchart of an air conditioning control method. 25 The air conditioning control system consists of an indoor unit, an outdoor unit, and at least one heating element located in the outdoor unit. a heat exchanger, a reservoir where condensed water collects, the condensed water that accumulates in the reservoir the level, parameters related to the cooling and heating modes of the air conditioner, heat exchanger This is for an air conditioner that includes a control unit that assesses the level of contamination on it, 30 When contamination is detected on the heat exchanger (101), the level of condensed water (102) checking the level of condensed water determined by the manufacturer. 4 at this level, operating the air conditioner in heating mode (103), condensation in the tank directing the water onto the heat exchanger (104), then cooling the air conditioner operation in mode (105) and contamination on the heat exchanger by the manufacturer If it is below the determined value, (106) heat exchanger cleaning function Completion includes (107) steps.
