Automobile air conditioner evaporators are roughly divided into two types, one is the evaporator that cools the liquid refrigerant, and the other is the evaporator that cools the air to absorb the heat in the car. So do you know the difference between the evaporator and the condenser of the car air conditioner? Next, I will introduce the difference between the evaporator and the condenser of the car air conditioner.
The difference between evaporation and condenser of auto air conditioner: Difference Introduction
1. Different Installation Positions: the condenser is installed in front of the water tank, outside the car, and the evaporator is installed under the dashboard and in the car;
2. Different functional characteristics: the condenser cools the high-temperature and high-pressure gas, and the evaporator exchanges heat between the low-temperature and low-pressure liquid and the air in the car to take away the heat in the car!
Difference between evaporation and condenser in car air conditioning: Purpose
An air conditioner evaporator is a type of evaporator. The function of the air conditioner evaporator is to use the liquid low-temperature refrigerant to evaporate easily under low pressure, convert it into vapor and absorb the heat of the cooled medium to achieve the purpose of refrigeration.
It relies on the fan to force the air in the warehouse to flow through the cooling pipes in the box for heat exchange, so as to cool the air, so as to achieve the purpose of reducing the temperature of the warehouse. Among them, the refrigerant or carrier refrigerant flows in the exhaust pipe, and the air outside the pipe is cooled by the pipe wall is called a dry air cooler; the sprayed refrigerant liquid directly exchanges heat with the air, which is called a wet air cooler; In addition to the cooling exhaust pipe, the hybrid air cooler also has a spray device for the refrigerant. Dry air coolers commonly used in cold storage can be divided into two types: ceiling type and floor type according to their installation positions.
The difference between evaporation and condenser of auto air conditioner: Function
The basic requirements of the evaporator are the same as those of the condenser. Because it is placed in the car, its anti-corrosion performance is not as high as that of the condenser, but the space inside the car is limited, so it puts forward more stringent requirements for its volume.
The function of the evaporator is to evaporate the low-pressure refrigerant from the expansion valve and absorb the heat of the air in the car, so as to achieve the purpose of cooling the car. Evaporators only need to have tube and fin type. Tube and strip and stacked. At present, all-aluminum laminated and tube-belt evaporators are mainly used on cars in my country, copper-tube aluminum-sheet evaporators are mainly used on large passenger cars, and there are several forms on medium-sized buses, mainly tube-belt type. For example, the air conditioners of Audi A6, Baolai, Honda, Buick, Sail, Shanghai Passat and other cars all use stacked evaporators, and the air conditioners of Santana 2000 sedan use tube-band evaporators.
Different types of evaporators have different cooling media. Some are cooled by water, brine or ethylene glycol aqueous solution, and the other is cooled by air. Today I will introduce you here, so do you know the difference between the evaporation and the condenser of the car air conditioner.
