Priora life hack: climate control - in a car with air conditioning

Comfort in the car is achieved through comfortable seats, a working stove, air conditioning and many other details. Air conditioning is not installed in all cars, underestimating its role. On the Priora, for example, this is a luxury package.

In summer, it helps combat the heat - with open windows and conventional climate control, it’s not always comfortable. But when a Lada Priora with air conditioning is stuck in a traffic jam, the driver and passengers will still not be hot - there is no wind outside, but a pleasant microclimate is created. Climate control on the stove is good, but it’s still not air conditioning.

The scale of the disaster can be assessed using a sensor that records the ambient temperature. It transmits the received data to the dashboard display. It is impossible to reduce the temperature without moving in a standing flow - and they are trying to fight this. in Priora it is quite an expensive pleasure, and experienced car enthusiasts install air conditioning after purchasing a car. The price depends on the brand Hull or Panasonic, the first starts from 30 thousand. Installation is also not cheap, starting from 8 thousand. You can sell a Priora with air conditioning at a higher price.

The air conditioner for the Priora car is produced by Russian and foreign companies. The price is indicated for a set with highways. The kit is so convenient and functional that you can view the air temperature on the display of the air conditioning control panel, which is mounted in the center console.

Tips for motorists

As an additional option, you can install air conditioning on the Lada Priora passenger car. They are supplied to the VAZ automobile plant by two foreign companies. The first company, Panasonic Taiwan Co. Ltd, is located in Taiwan, and the second is in South Korea (Halla Climate Contro). Here is one of the air conditioners from these companies that will be installed on your car. The designs of these air conditioners are not fundamentally different, but their components are not interchangeable.

An air conditioner malfunction associated with a failure of the electromagnetic clutch of the compressor drive can be determined by ear or by tachometer readings. Since with a working electromagnetic clutch, when the air conditioner is turned on, the crankshaft rotation speed decreases, which leads to a noticeable change in the tone of the running engine, and if at this moment you look at the tachometer, it will show that the crankshaft speed has decreased. And if, after pressing the air conditioning button, the crankshaft speed remains at the same level, it means that the electromagnetic clutch did not work.

We carry out comprehensive diagnostics

Not so easy. Even experienced motorists cannot cope with this task quickly. To avoid doing such a large amount of work in vain, it is better to first diagnose the heating system. You must proceed as follows:

We probe the channels through which the coolant flows to the heater. They should be warm when the stove is on. In addition, when pressing on the main rubber hoses, resistance should be felt. If resistance is not felt, the pump pump may be faulty. This mechanism is responsible for creating the pressure of fluid flows necessary for normal operation of the heater.
A little secret that may be useful to Lada Priora owners: does the stove blow cold air for a long time and does not warm up as quickly as we would like? Then you can try filling coolant to the bottom mark in the tank. In this case, the liquid will warm up faster. If you practice this method, you will need to constantly check the coolant level.
If it works, then we can talk about a problem in the bearing, which is located on the electric fan. This situation cannot be ignored, since in the future the fan may jam and repairs will take place on a much larger scale.
Is the stove not working? Perhaps the problem is hidden in fuse F9 with a rating of 25 A. Its function is to protect the power electrical lines of the heater. A blown fuse must be replaced. If such a situation occurs with enviable consistency, then it is necessary to check all electrical circuits of the heater, the insulation of the windings on the fan and the presence of an overload in the power circuit.

What does the air conditioning system in Priora consist of?

Regardless of the company, the air conditioner kit for Lada should contain the following elements:

Air conditioning compressor assembly;
Condenser with receiver assembly;
Evaporation block assembly;
Air conditioner radiator for Lada Priora;
Highways;
Cushion bracket;
Generator bracket;
Tensioner bracket;
Tensioner roller;
Compressor drive belt;
Rubber seal;
Installation kit;
Wire harnesses.

Device principle

Next, let’s look at the Panasonic air conditioner circuit, which consists of the following components:

The compressor is a single-pass rotary with three blades. This element builds up the required pressure and maintains the circulation of the refrigerant. The compressor is located under the generator.
A condenser is a heat exchanger that provides cooling to a gaseous refrigerant by turning it into a liquid state. This mechanism is located on the radiator frame.
The evaporator is also a heat exchanger; its purpose is to cool and dry the air before it enters the cabin. This device is located in the heater housing.
The receiver has the shape of a metal cylinder, which is connected to the capacitor. This mechanism ensures the accumulation of liquid refrigerant and separation of moisture and debris. There is a filter drier inside the receiver.
Pipelines.

This is the element that is added to the Priora stove with air conditioning. Now that you know the structure of the stove in the Lada Priora, troubleshooting will be much easier.

Operating mode of climate control and air conditioning on Lada Priora

The factory installs climate control on the Priora in all trim levels, and in all air conditioners it is turned on in the “Auto” position. In this mode, the electronic control unit, which is located behind the center console, receives data on the ambient air temperature and the interior air temperature. Based on this data, the ECU regulates the “force” that the “conder” produces to maintain the mark set by the person.

For example, if a person has set a constant temperature of +19 ֯С, the ECU will regulate the power of the air conditioner, constantly sending it commands. Working at this pace, the air temperature in the cabin will be maintained at +19 °C.

Air conditioner malfunction

A Conder can break down; the reason for this is not always the negligence of manufacturers towards their product. Most often, a small component fails, which can be easily replaced and then continue to use the Conder. If the air conditioner does not turn on, then:

There is damage in the wiring;
Thermostat is faulty;
The fuse has blown;
Lack of freon in the system;
Pressure sensor malfunction;
Excessive system pressure.

If the air conditioner does not work, then this is not a reason to throw it away. All the necessary spare parts for an air conditioner can be found in Lada, they will not cost much.

Does fuel consumption increase with air conditioning?

In order to drive air inside the device, cool it and release it outside, you need to take energy. What contributes to energy production? Of course the engine is running. The harder it works, the more devices can receive stable “recharge”, and, accordingly, the higher the engine consumption becomes.

Initially, Lada is not ready for the air conditioner to operate, so it has to use additional resources in the form of fuel. Consumption from 100 km increases by 1 liter. By the way, to be fair, we note that the dynamics of the car do not decrease.

Factory air conditioner, Halla and Panasonic - differences, articles

Most often, Conders from August, Panasonic and Halla are considered as an installation option. The Russian product is cheaper, but it has its disadvantages:

Short-lived compressor;
Lack of cabin air filter;
To charge coolant you will have to remove the radiator;
The evaporator housing is made of plastic and is easily deformed.

But there is good, healthy competition between the other two brands. If you look at and buy Halla or Panasonic, you need to take into account their differences:

Airflow speeds. Panasonic has 16, Halla has only 4;
Halla's engine radiator will house the engine cooling fan along with the air conditioning condenser;
Panasonic's control knobs are capable of turning on the glass blowing, directing all the power only to them. Halla does not have such buttons or handles;
Panasonic's upper line is flexible, while Hull's is aluminum.

The entire Halla air conditioner for Priora can be purchased for around 30 thousand rubles - slightly cheaper than a kit from Panasonic. Installation of a Panasonic air conditioner in a technical center costs approximately 8,500 rubles, and Halla is a little cheaper (some prices are the same). It will be easy to distinguish them by article number. Panasonic has 2170-8122020-01, Calla has 2170-8122020-11.
