When cold weather in our daily life conditioned car heater become indispensable, especially the recent frequent activities of cold air, the southern region has been covered by rain and snow, the sky is difficult to clear up. Previously we focused on the use of air conditioning heater doubts were repeated testing, but how to use the heater for the air conditioning, and vehicle air conditioning works we have not introduced the relative system, and we want to talk about today's topic is the .
When it comes to how to use the air conditioner heater, I believe there will be some disdain many users think it is nothing to say, but a closer look will find that many owners was not very clear on the use of air conditioning in warm air, it appears that the basic operation or it is necessary to come to talk of.
In terms of vehicle air conditioning works, for most car owners knowledge or blind, little known about them, and today we hope that we can so as to facilitate their future life by understanding the car air conditioning works. Next, we start talking about a vehicle air-conditioning works.
● automotive air conditioning works
Automotive air conditioning system generally consists of a compressor, condenser, drier, expansion valve, evaporator box, air conditioning ducts, electric clutch and other components. One car air conditioning cooling medium, namely universal refrigerant for R134a, which continues to cycle through the various components of air conditioning, and use instant volume compression release its rapid expansion is necessary to absorb a lot of heat in the cooling principle.
Commonly used models on the market today non-independent air-conditioning, when we press A / C button, the electromagnetic clutch is energized by an electromagnetic coil magnetic engine belt with suction cups together, so as to drive the air conditioning compressor operation.
After the compressor work, from out of the low-temperature evaporation tank pressure gas refrigerant flows through the compressor into high temperature high pressure gas refrigerant, after cooling the condenser temperature high-pressure liquid pipe is formed, then after dehumidification drier dried, flows to the expansion valve when the air conditioning duct is widened due to the pressure subsequently decreases, the refrigerant temperature low-pressure liquid refrigerant and the low pressure environment, i.e., a case of evaporation, and to absorb a lot of heat. For air constantly flowing through the evaporation tank, inside temperature is decreased, the humidity drops. Liquid refrigerant flows into the evaporation tank again after the low-pressure gas, sucked into the compressor again for the next cycle of work.
Top automotive air conditioning works we introduced mainly for its refrigeration, and automotive air conditioning and heating and A / C does not matter, but by the heater tank (coolant) from the heat, the engine is in operation generated a lot of heat and cooling to the recycling compartment, so as to achieve the purpose of air conditioning and heating.
● automotive air conditioning heater use
Keys on the car air conditioner panel is not much, but exactly how to adjust them to make winter warmer inside, allowing occupants safer but implied tips, here we give you the use of air conditioning warm reminder.
Car to heat:
Principle of the above, we have said, the car air-conditioning and heating function is performed by the heat from the heater tank, so if you want air conditioning blowing warm air, the premise of the vehicle must be in normal temperature, which is the vehicle to be in hot car status. Otherwise, jump start with air conditioning, air conditioning will cool breeze blowing whistle.
Air-conditioning cycle mode:
According to our previous conclusions after the test, in the open early in the cycle air conditioning heater selection mode will bring better car warming effect, raise the temperature in the car to a certain extent, in order to ensure the flow of air inside the car, and we it is recommended that you switch the air conditioner in a timely manner to the outer loop mode. Of course, this also depends on your area's weather conditions may be.
Set the air temperature:
Maybe a lot of people think that the air temperature is set as high as possible, in fact Definitely not. The air temperature is too high, although the car will make rapid warming, but higher temperatures will slow driver reaction, car passengers will feel unwell, so in order to strike a balance between comfort and safety, we recommend that you set the air temperature preferably at about 22 ℃.
Set conditioned air volume:
Same as above mentioned setting air conditioning temperature, the excessive amount of warm air will affect the ride comfort of the passengers in the car, but also affect the driving safety of the driver, so we suggest that you use air conditioning in warm air when the air conditioning air flow transferred to the middle or lower gear.
Set the air conditioning airflow:
Air conditioning airflow generally be divided into the head, upper body, feet, etc., in the air conditioning panel will have the image of the icon to be noted. To be able to feel the warmth quickly, we can wind blowing straight transferred to the upper body, and if cold feet can be adjusted to the wind blowing foot.
Switch A / C:
A / C compressor switch that is, if the vehicle is equipped with automatic air conditioning will find press AUTO (auto) button, A / C will be opened at the same time. However, according to the principles of automotive air-conditioning, heating its compressor does not function, that the switching A / C cases have no effect for the heater.
As for the winter indoor and outdoor temperature, vehicle glass is easy to form fog phenomenon, the use of air-conditioning compressor can indeed achieve dehumidification function, but if you need to open A / C were based on different regions have different defogging humidity analysis of specific issues.
Windshield defogging functions:
Front of the vehicle, rear window demister has a separate function keys, they also have a rapid demisting function, but the manner and the site defogging differ Bale. And when you open the front windshield defogging function, A / C will be opened at the same time, to provide protection for demisting function. Of course, if you are in relatively dry area, manually shut down A / C defogging same effect can be achieved, but also save fuel.
