CAR AIR CONDITIONERS GAS LEAKS.

Automobile manufacturers are shown in the drawing according to the most important gas leaks.
The compressor shaft manufacturers in the annual maximum of 10-30 grams of gas loss is considered to be inevitable. (4 pieces "!" is shown with.)
Hose system, about 10-20 grams, 2-3 grams each, including an O-ring from 42-83 grams of total annual gas leak and a "normal" is considered.
The newly developed air-conditioning systems, desiccant-condenser, expansion valve-evaporator is manufactured with the reduced number of connections and the gas leakage is reduced accordingly. (annual total of 52 g leakage)

STUDY OF AIR-CONDITIONING SYSTEM.

Compressor, air-conditioning condenser compresses the gas. Increasing air pressure and temperature of gas, condensed into a liquid passes into the average temperature of 60 °. Condenser, while in the car cruising in parks or in congested traffic with the outside air cools the condenser fan. High pressure gas in liquid form, air conditioning, expansion valfından, passes through a large volume and pressure drops.
In the form of liquid refrigerant, evaporator evaporates in the heat around the balls. Evaporator surface and the surrounding area "to -10 ° C" and "-18 ° C until it cools down. Cooling is provided as a result of the evaporator fan is controlled by the driver of this coolness is blown into the car. In this case, the liquid refrigerant into steam by the conversion of state of repeated again.

Automobile Air Conditioning Service Nitrogen (N) use.                                                      

Air-conditioning system provides excellent results while working on the nitrogen gas. Nitrogen is a dry and inert gas. At the same time can be obtained cheaper and easier. Pressure is required to control the pressure regulator. Appropriate equipment can be found in places that sell welding equipment. However, converting existing records is also required for air conditioning manifoldunuza connection.

Nitrogen gas is useful in finding air leaks.

Basınç altında kaçak arama yapılırken basınçlı hava kullanılmamalıdır. Basınçlı hava nem içerdiği için klima sistemine zarar vermektedir.

Air conditioning system shortens the duration of dry and vacuum.

Nitrogen gas before filling out the washing, drying and air-conditioning system in terms of review is a good practice. For this, the tip of one of the system is left open to the atmosphere. Nitrogen and air conditioning service manifold tube is connected to the other end and sent to the compressed gas air conditioning system. In this way, as a result of service or for other reasons to stay open longer during the air conditioning system is cleaned transmitted moisture. Another benefit of using nitrogen levels in the bottom stands for the duration of vacuum creation.
