All modern cars above the B-class are equipped with special equipment, which is designed to create an optimal climate in the car. These devices are called climate control. A modern system that creates optimal "weather conditions" in the cabin is an electronic complex, a climate control unit that controls the operation of the heater, fan, air conditioning system, as well as the distribution of air flows.
Until recently, and even now on budget cars, only a stove was installed, where you had to manually adjust the temperature regime and the force with which the air flow would be blown out. Yes, and the stove is operated more often than it is only in winter. In the summer, you can get by with an open window. But the development of technological progress has made the necessary contribution to the development of modern systems designed to provide comfort indriving process. Let's see what the climate control unit is, what such complexes can do and how they are controlled.
Device
Depending on the class and equipment of the car, the air conditioning system may vary significantly in functionality. But all of them are almost completely automated. The basis of the system is the control unit, which, through a huge number of sensors located in various places in the cabin, controls the operation of the actuators. This is an air conditioner, a stove, as well as filter elements.
Operation principle
The climate control unit receives data from sensors about the outside temperature. It also receives information about the levels of solar radiation. The device takes care of the he alth of the driver and passengers - the system changes the direction of air flow and ensures the most even distribution of warm or cold air around the entire perimeter of the cabin. This prevents the risk of diseases that may occur when using a conventional air conditioner.
What is the advantage of this complex complex? Unlike the archaic stove, the climate control unit does not immediately supply hot or cold air to the cabin. The air flows are first mixed in the air duct system, and only then the mixture is distributed throughout the cabin.
So, the system is able to maintain the set comfortable temperatures by regulating the flow of hot and cold air. Manufacturersclimate systems achieve this with the help of special air dampers. Changing their position leads to mixing of air of different temperatures. These shutters are controlled both manually and automatically using an electronic system.
Features of climate systems
The principle that underlies the operation of this system (namely, mixing hot and cold air streams) allows engineers to constantly increase the functionality of the systems to further increase comfort in the car. So, it was possible to create a completely autonomous system to ensure the microclimate, regardless of the weather.
Even a budget complex is able to quickly dry the air in the cabin in wet weather to prevent fogging of the glass. Also, the climate is able to remove dust and gases from the air - this is true for large cities. The system enables a person to gradually adapt to climatic conditions. Even the most budget-friendly solutions can function without the need for outdoor air intake.
Single-zone climate
The simplest climate control unit works on the principle of ensuring the same temperature at every point of the elephant. This scheme is single-zone. More complex systems may have other functions. So, they use different temperature settings in individual parts of the cabin. There are two-, three- and even four-zone climatic installations, where the system controls individual sections. We'll take a look at each one below.
Features of the two-zone system
Dual-zone climate control is a system that can provide and maintain different temperatures in different parts of the cabin. Such a complex is the most common among multi-zone ones. The unit allows you to set different temperatures near the driver's seat and at the location of the rear passengers.
A feature of this climatic complex is the presence of restrictions on the maximum temperature difference between two controlled zones. Often the difference is not high - no more than 6 degrees. If the driver has set their temperature to 26 degrees, then passengers in the back row on dual-zone climate control will not be able to adjust the temperature below 20 degrees.
Three-zone climate control
In such systems, you can adjust the temperature in the driver's area, near the front passenger, as well as in the back row.
Four-zone
Such complexes are installed only on premium cars, and even then not in every configuration. The system allows you to adjust the comfortable temperature near each seat. Considering that a private car is not often fully loaded, then setting the climate control to four zones is redundant. These systems have the same temperature restrictions between two adjacent zones.
Any multi-zone system for its full-fledged work requires a much larger number of air-conducting systems, a huge number of sensors and dampers. All this is managedseparate block.
Climatic system options
Many car owners who have moved from an old Zhiguli to a decent car do not know how to use climate control. Despite the constructive complexity of the system, it is as user-friendly as possible. All manipulations are carried out from a very simple and intuitive control panel. You don't even need to open the instruction manual to understand the meaning of the controls.
Distinguish between manual operation of the climate complex and automatic. In the first case, you need to thoroughly know all the subtleties of the climate. If, unknowingly, the system is incorrectly configured from the climate control panel, there is a risk of reducing the life of the entire complex.
In manual mode, by turning the knobs or pressing the buttons, the fan speed, the level of cooling or heating of the air is adjusted. The conditions for air entering the passenger compartment are adjusted. Manual mode is for when you need to heat or cool the air very quickly.
Auto mode is used for long trips. To activate this mode, you need to press the corresponding button and set the comfortable temperature. All actions for setting the dampers, air flows and their strength, the control unit will take over.
Car enthusiasts often don't use automatic modes (and not because they don't know how to use climate control). If this scheme is chosen, the fan is very annoying - itruns at high speeds, making noise. But this is only the initial stage of work - after a few minutes the fan will switch to normal mode and stop making noise. The system will only maintain the set temperature.
In conclusion
The installation of climate control made the car even more comfortable. In summer or winter, the temperature in the cabin will be the most optimal. And passengers will be able to adjust the temperature to their taste. This is a very useful feature.
