1 TARIFF AN AIR CONDITIONING AND CONTROL METHOD This invention allows for the detection of contamination on the heat exchanger and the subsequent treatment of the heat exchanger. It relates to an air conditioning control method concerning cleaning. 5 Air conditioners perform functions such as heating, cooling, dehumidification, and air circulation. These are the devices that enable this. Household air conditioners consist of an indoor and an outdoor unit. It consists of two main interconnected parts: the indoor unit, the heat exchanger, and the crossmember. The airflow fan, fan motor and control unit, and the outdoor unit, control unit, heat exchanger, 10 throttling element, four-way valve, compressor, axial fan, and fan motor. It includes. Air conditioners operate according to the vapor compression refrigeration cycle. The pressurized refrigerant, in the form of superheated vapor, exits the compressor and flows to the outdoor unit. air enters the heat exchanger and passes through the heat exchanger with the help of a fan. During the process, the coolant's heat is released to the external environment. In the liquid state, the heat is 15. The coolant exiting the heat exchanger enters the throttling element. Throttling The refrigerant, whose pressure and temperature are reduced in the valve, is transferred to the indoor unit heat exchanger. It enters here by passing air through the heat exchanger with the help of a fan. Heat is extracted from the environment. It exits the heat exchanger in the form of superheated steam. The refrigerant enters the compressor and the refrigerant cycle continues in this way. 20 This is repeated. In cooling mode, the outdoor unit heat exchanger is the condenser, and the indoor unit... The heat exchanger acts as an evaporator. Heat extracted from the environment is transferred to the outside environment by passing air through a heat exchanger. Since air is expelled, airflow affects air conditioning performance. The air is 25... As the air flow rate decreases, the heat released into the environment also decreases. Furthermore, as the air flow rate decreases... Because the condensation pressure and temperature increase, the power drawn by the air conditioner also increases. This In this situation, the efficiency of the air conditioner decreases. The main reason for the decrease in the outdoor unit airflow is... A major factor is the fouling of the heat exchanger. The air conditioner's outdoor unit is exposed to the outside environment. Therefore, it is exposed to external factors such as dirt, dust, pollen, and the like. Temperature 30 Contamination of the heat exchanger creates additional resistance on the fins, thus hindering heat transfer. is decreasing. 2 In the current state of the art, heat exchanger fouling affects air conditioning performance and Its effect on air flow is quite significant.
