Answer :
In air conditioners, a heat exchanger is typically used to transfer heat from one fluid to another, either from the air inside a building to the outdoor air, or from refrigerant to the air. The two most common types of heat exchangers used in air conditioners are the evaporator and the condenser.
What is Heat exchanger?
A heat exchanger is a device that is designed to transfer heat from one fluid or gas to another fluid or gas, without allowing them to mix. The two fluids are separated by a wall, or a series of walls, which allow heat to be transferred through conduction.
Heat exchangers are used in a wide range of applications, including power plants, chemical plants, refrigeration systems, HVAC systems, and various industrial processes. The design of heat exchangers can vary greatly depending on the specific application and the type of heat transfer that is required. Some common types of heat exchangers include shell and tube, plate and frame, and air-to-air heat exchangers.
In air conditioners, a heat exchanger is typically used to transfer heat from one fluid to another, either from the air inside a building to the outdoor air, or from refrigerant to the air. The two most common types of heat exchangers used in air conditioners are the evaporator and the condenser.
The evaporator is typically a coil filled with refrigerant, which absorbs heat from the indoor air as it evaporates. The condenser is also a coil, but filled with a different type of refrigerant, which releases heat to the outdoor air as it condenses.
Both the evaporator and condenser are typically made of metal, such as aluminum or copper, and are designed to maximize heat transfer and minimize resistance to fluid flow. The exact design of the heat exchanger depends on the specific requirements of the air conditioner, including the desired cooling capacity, the temperature and pressure of the refrigerant, and the ambient temperature and airflow around the unit.
