There are five main components to the whole auto air conditioning system, namely the Compressor, Condenser, Receiver-dryer, Expansion valve, and the Evaporator. Hard tubing and flexible hoses connect all the actual components of the air conditioning in the car. The fluid that passes around the whole system is the refrigerant. Earlier, R-12 was the refrigerant used in almost all cars. But due to its environmental damaging properties, the refrigerant was discontinued (Banned) . Today, a HCFC called R-134A is widely used. It is harmless to the environment.

Copper occurs naturally in the Earth̢۪s crust in a variety of forms. With its unique combination of properties, copper has myriad uses. It is one of the most recycled of all metals and it is 100% recyclable without any loss of quality. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.

Storage at low temperatures prolongs the shelf life of many foods. In general, low temperatures reduce the growth rates of microorganisms and slow many of the physical and chemical reactions that occur in foods. Freezing and frozen storage provide an excellent means of preserving the nutritional quality of foods. At subfreezing temperatures the nutrient loss is extremely slow. Cold room allows precise regulation of temperature and humidity and maintenance of constant conditions by use of a refrigeration and ventilation system. The life of many foods may be increased by storage at temperatures below 4° C (40° F). Commonly refrigerated foods include fresh fruits and vegetables, eggs, dairy products, and meats. Extreme temperatures can have a big effect on both prescription and over-the-counter drugs. Many medicines require storage between 2°C and 8°C. Some products can be irreversibly degraded even by brief periods at sub-zero temperatures, and so monitoring of storage temperature is vital. For vaccines and refrigerated medicines to remain effective it is important they are stored within the recommended range of +2º and +8 ºC, to ensure potency Hence cold rooms are extremely vital in the field of medicine and chemical manufacturingprocessing.

Air conditioning can refer to any form of technology that modifies the condition of air (heating, cooling, de-humidification, cleaning, ventilation, or air movement). However, in construction, such a complete system of heating, ventilation, and air conditioning is referred to as HVAC The major parts of an air conditioner are – Evaporator – Receives the liquid refrigerant Condenser – Facilitates heat transfer Expansion valve – Regulates refrigerant flow into the evaporator Compressor – A pump that pressurizes the refrigerant
