Evaporator is an important component AS WELL AS compressor , condenser and expansion devices. Components of a cool ing load . How an Air Conditioner Works. Now, around 97% of homes in the South and 65% of homes in the western United States have a cooling system. Some of variations are The compressor manufacturer Piston The Compressor The Condenser The Receiver/Dryer or Accumulator The Thermal Expansion Valve or Orifice Tube The Evaporator The Refrigerant Typical A/C System and Flow. Expansion devices: • Capillary tube 25 The chilled water types of central air conditioning plants are installed in the place where whole large buildings, shopping mall, airport, hotel, etc, comprising of several floors are to be air conditioned. The compressor functions together with a substance called working fluid that can easily transform from gas into a liquid. While each of the three types differ, the concept and design are very similar to one another. The high pressure and high temperature vapour refrigerant then flows to the condenser through the open outlet valve. A short summary of this paper. 1. Looks like you’ve clipped this slide to already. Expansion valve- It is a device used in car air conditioning system to expand the high pressure, low … Receiver-Dryer-6. The liquid refrigerant leaving the expansion valve is quite cold. 2.

Always use genuine Toyota R 134a system 0–rings and seals for R 1 34a air conditioning systems. The evaporator in the air handling unit of the DX central air conditioning system is of coil type covered with the fins to increasing the heat transfer efficiency from the refrigerant to the air. Multi Head Systems also allow for individual control of the air conditioning in each room, optimising comfort levels and offering savings on running costs. Many people think an air conditioner works to add coldness to the air, but it actually works to remove heat. An air conditioner (AC) in a room or a car works by collecting hot air from a given space, processing it within itself with the help of a refrigerant and a bunch of coils and then releasing cool air into the same space where the hot air had originally been collected. To begin with, there are five basic components of an air conditioning system which enable it to provide cooling and heating, as required. Taken literally, air conditioning includes the cooling and heating of air, cleaning and controlling its moisture level as well as conditioning it to provide maximum indoor comfort. Expansion devices: • Following are the main types of expansion devices used in industrial and commercial refrigeration and air conditioning system. It uses when the airflow is more than 300 m³/min or different zones in a building are to be air-conditioned. Title: Air Conditioning System Components 1 Air Conditioning System Components. Now customize the name of a clipboard to store your clips. Of all the HVAC services our contractors perform, air conditioning is the most requested service. August 11, 2017. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Luckily, one of the greatest engineering accomplishments over the centuries has been the development and evolution of refrigeration. Condenser – 3. An air conditioner is able to cool a building because it removes heat from the indoor air and transfers it outdoors. An air conditioner transfers heat from the inside of a building, where it is not wanted, to the outside. Depending upon the comfort of the human beings and the control of environment for the industrial products and processes, air conditioning can also be classified as comfort air conditioning and industrial air conditioning. See our Privacy Policy and User Agreement for details. However, unlike window air conditioner or PTAC units, it has a higher cooling or heating capacity and is usually able to cool an entire house or a commercial building. High pressure liquid turns to the low pressure liquid. The winter air conditioning uses a heat pump (refrigeration system operated in the reverse direction) and a humidifier.

The most common components which make up these automotive systems are the following: 1. The compressor of the car air conditioning system is driven by the crankshaft of the engine through the belt drive. Download PDF. In the typical split-air conditioning system, the four basic components are separated into two sections indoor and outdoor. These two parts are the air handler, heating and cooling system, and the heat exchanger. Condenser – It is the device looks like a small radiator and is used after the compressor as it provides condensing i.e. An air conditioner is able to cool a building because it removes heat from the indoor air and transfers it outdoors. components, such as the ducts, pip ing, air conditioning fan and pump etc. Presentation Summary : EVAPORATOR It consist of a refrigerant coil mounted in a series of thin cooling fins.
