AC technician refrigeration course in wah

In refrigeration, there is a transfer of thermal energy from a place at a cold temperature to a place at a higher temperature. In AC, thermal energy is taken away to keep the air at a cool temperature. The refrigeration parts include a compressor, condenser, and evaporator in one unit.
temperature and temperature measurement, pressure and pressure measurement as well as heat and heat transfer. You will also study heat transfer in the basic cycle, pressure temperature relationships, the refrigerant condition in the system components and the basic cycle components.
The vapor compression refrigeration cycle is a common method for transferring heat from a low temperature to a high temperature. The objective of a refrigerator is to remove heat (𝑄𝐿) from the cold medium; the objective of a heat pump is to supply heat (𝑄𝐻) to a warm medium.
Air-conditioning is that process used to create and maintain certain temperature, relative humidity and air purity conditions in indoor spaces. This process is typically applied to maintain a level of personal comfort.
Industrial refrigeration is a specialized field that deals with cooling and freezing large-scale industrial processes and equipment. It is essential in food and beverage, pharmaceuticals, and chemical manufacturing industries, where temperature control is critical to maintaining product quality and safety.
Perhaps the most popular application of industrial refrigeration systems is in the processing and production of food and beverage. Refrigeration is an essential element in food safety, avoiding food waste, and food preservation.
There are three primary functions to a room Air Conditioner. First is to cool a specific area, such as a room, not an entire home. The second is to dehumidify, to remove moisture out of the air, so you're not sitting in a cold, clammy environment. The third function is to filter the air within the home.
The compressor of an air-conditioning system is considered to be the engine of the unit. Thus, the compressor is the most important component of your AC unit. This functions together along with a substance known as working fluid. Together, they help to transform the gas into a liquid.23
