The control unit is climate control. Dual-zone climate control: manual

All modern cars above the B-class have inspecial equipment, which is designed to create the optimum climate in the car salon. 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, and air distribution.

Until recently, and now on a budget car,Only the stove was installed where it was necessary to manually adjust the temperature regime and the force with which the air flow would be blown. And the stove is operated more often only in the winter. In the summer, you can do without an open window. But the development of technical progress has made a necessary contribution to the development of modern systems designed to provide comfort in the process of driving. Let's see what the climate control control unit is that they know how to handle such complexes and how they are managed.

Device

Depending on the class and equipmentcar, air conditioning can vary significantly in functionality. But they are almost completely automated. The basis of the system is the control unit, which, through a huge number of sensors located at various locations in the cabin, controls the operation of the actuators. This is an air conditioner, a stove, as well as filter elements.

Operating principle

The climate control control unit receives datafrom sensors about the outside temperature. It also receives information on the levels of solar radiation. The device takes care of the health of the driver and passengers - the system changes the direction of the air flow and provides the most uniform distribution of warm or cold air around the perimeter of the cabin. Thus, the risk of diseases that can occur when using a conventional conditioner is prevented.

What is the advantage of this complex complex? Unlike the archaic stove, the climate control unit does not immediately deliver hot or cold air to the salon. Air flows are first mixed in the duct system, and only then the mixture is distributed throughout the cabin.

So, the system can support customizedComfort temperatures due to the regulation of hot and cold air flows. Manufacturers of climate control systems achieve this with the help of special air dampers. Change of their position leads to mixing of air of different temperature. These valves are controlled either manually or automatically by means of an electronic system.

Features of the work of climate systems

The principle that underlies thissystems (namely the mixing of hot and cold air currents), enables engineers to continually increase the functionality of systems to further enhance comfort in the car. Thus, it was possible to create a completely autonomous system to ensure the microclimate, regardless of the weather.

Even a budget complex can quickly drainair in the cabin in wet weather to prevent fogging the glass. Also, the climate is able to remove dust and gases from the air - this is important for large cities. The system allows a person to adapt to climatic conditions gradually. Even the most budgetary solutions can function without the need for air intake from the street.

Single-zone climate

The simplest climate control unit works onthe principle of ensuring equal temperatures at each point of the elephant. This scheme is single-band. More complex systems can have other functions. So, they use different temperature settings in individual parts of the cabin. There are two-, three-, and even four-zone climatic systems, where the system monitors individual sites. Below we will consider each of them.

Features of the two-zone system

Dual-zone climate control is a system,capable of providing and maintaining a different temperature in different parts of the cabin. Such a complex is the most widespread among multi-zone ones. The unit makes it possible to set different temperatures around the driver's seat and at the location of the rear passengers.

The peculiarity of this climatic complex inthere are restrictions on the maximum temperature difference between the two monitored zones. Often the difference is not high - no more than 6 degrees. If the driver has set a temperature of 26 degrees, the passengers in the back row on the two-zone climate control can not adjust the temperature regime below 20 degrees.

Three-zone air conditioner

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 the carpremium, and even then not in every configuration. The system allows you to adjust the comfort temperature near each chair. If you consider that a personal car is not often loaded completely, the installation of climate control in four zones is redundant. In these systems, there are the same restrictions on the temperature regime between two neighboring zones.

Any multi-zone system for its full operation requires a much larger number of air-conducting systems, a huge number of sensors and dampers. All this is controlled by a separate unit.

Variants of operation of the climate system

Many car owners who moved withold "Zhiguli" for a decent car, do not know how to use climate control. Despite the constructive complexity of the system, for the user it is maximally friendly. All manipulations are carried out with a very simple and intuitive control panel. To understand the importance of controls, you do not even need to open the operating instructions.

There are manual operation of climaticcomplex and automatic. In the first case, one must thoroughly know all the subtleties of the climate work. If ignorance is incorrect to adjust the system from the climate control panel, there is a risk of reducing the life of the entire complex.

In manual mode by turning the knobs orPressing the buttons adjusts the fan speed, cooling or heating level. The conditions for getting air into the cabin are adjusted. Manual mode is intended for those cases when it is necessary to warm up or cool the air very quickly.

Automatic mode is applied in the conditionlong trips. To activate this mode, you need to press the appropriate button and adjust the comfort temperature. All actions for setting the dampers, air flows and their power, the control unit will take over.

Motorists often do not use automaticregimes (and not because they do not know how to use climate control). Given the choice of this scheme, the fan is very annoying - it operates at high speeds, creating noise. But this is only the initial stage of the work - in a few minutes the fan will go into normal mode and will cease to make noise. The system will only maintain the set temperature.

Finally

Installation of climate control has made the car moremore comfortable. Summer or winter temperatures in the cabin will be the most optimal. And passengers will be able to adjust the temperature regime to your taste. This is a very useful feature.
