How does it work?
Refrigeration and air conditioning is used to cool products or a building environment.
The refrigeration or air conditioning system (R) transfers heat from a cooler low-energy reservoir to a warmer high-energy reservoir
There are several heat transfer loops in a refrigeration system as shown in Figure 2. Thermal energy moves from left to right as it is extracted from the space and expelled into the outdoors through five loops of heat transfer:
Indoor air loop. In the left loop, indoor air is dr ....etc

How does it work?
Cooling and air conditioning used to cool products or construction environment.
Refrigeration system or air conditioning heat from a cold into a warm layer of low energy high energy reservoir
There are several heat transfer loop cooling system, as shown in Figure 2. Heat energy moves from left to right, which is derived from the area and expelled into the air through five loops of heat transfer:
Indoor air loop. In the left loop, the air is fresh air through the cooling coil, where it transfers its heat to chilled water. Then ....etc

A mechanism is a simplified model, usually in the form of a line diagram, which is used to reproduce the movement occurring in a machine. The purpose of this reproduction is to allow the nature of the machine. The purpose of this reproduction is to allow the nature of the movement to be investigated without the imposition of the various solid bodies forming the machine elements. The various parts of the mechanism are called links or elements. An arbitrary set of couplings forming a Closed which is capable of relative ....etc

Air conditioning (often referred to as AC, A.C., or A/C) is the process of altering the condition of air by removing heat and humidity to achieve a more comfortable interior environments, typically with the aim of distributing the conditioned air to an occupied space such as a building or a vehicle to improve thermal comfort and indoor air quality. In common use, an air conditioner is a device that removes heat from the air inside a building or vehicle, thus lowering the air temperature. The cooling is typically achieved through a refrigeration ....etc

An absorption refrigerator is a refrigerator that uses a heat source (e.g., solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems) to provide the energy needed to drive the cooling process.
Absorption refrigerators are often used for food storage in recreational vehicles. The principle can also be used to air-condition buildings using the waste heat from a gas turbine or water heater. Using waste heat from a gas turbine makes the turbine very efficient because it first produces electricity, then hot water, ....etc

The objective of this project is to detect any leakage of
LPG/CNG based cars, small scale factories or in home
appliances also. It will detect the leakage and will close the
knob of the system to stop the supply of the gas. Stepper
motor is there that could be attached with the knob and will
close the supply by rotating it. For assistance and LCD of
16x2 is also there. An alarm is there also the stop the alert the
user as soon as leakage is found.
Gas sensors are employed in a wide range of applications in
the fields of safety, health, ....etc
